防火板特点

　　Characteristics of fireproof board

　　1、保温隔热：其保温、隔热性是玻璃的六倍、粘土的三倍、普通混凝土的十倍；

　　1. Thermal insulation: Its thermal insulation and insulation properties are six times that of glass, three times that of clay, and ten times that of ordinary concrete;

　　2、轻质高强：为普通混凝土的1/4、粘土砖的1/3，比水还轻，和木材相当；立方体抗压强度≥4mpa。特别是在钢结构工程中采用ALC板作围护结构就更能发挥其自重轻、强度高、延性好、抗震能力强的优越性。

　　2. Lightweight and high-strength: 1/4 of ordinary concrete and 1/3 of clay bricks, lighter than water and comparable to wood; Cube compressive strength ≥ 4mpa. Especially in steel structure engineering, using ALC panels as enclosure structures can better leverage their advantages of light weight, high strength, good ductility, and strong seismic resistance.

　　3、耐火阻燃：加气混凝土为无机物，不会燃烧，而且在高温下也不会产生有害气体；同时，加气混凝土导热系数很小，这使得热迁移慢，能有效抵制火灾，并保护其结构不受火灾影响。

　　3. Fire resistant and flame-retardant: Aerated concrete is an inorganic substance that does not burn and does not produce harmful gases at high temperatures; At the same time, the thermal conductivity of aerated concrete is very low, which slows down heat transfer, effectively resists fires, and protects its structure from the impact of fires.

　　4、加工方便：可锯、可钻、可磨、可钉，更容易地体现设计意图；

　　4. Convenient processing: sawable, drillable, grindable, and studable, making it easier to reflect design intent;

　　5、吸声隔音：以其厚度不同可降低30～50分贝噪音；轻质条板系列的内部组成材料（EPS聚苯乙烯颗粒）具有良好的隔声性能和吸声功能。

　　5. Sound absorption and insulation: Different thicknesses can reduce 30-50 decibels of noise; The internal component material of the lightweight strip board series (EPS polystyrene particles) has good sound insulation and absorption properties.

　　6、适应承载：风荷载、雪荷载及动荷载。

　　6. Adaptive bearing capacity: wind load, snow load, and dynamic load.

　　7、耐久性好：ALC板是一种硅酸盐材料，不存在老化问题，也不易风化，是一种耐久的建筑材料，其正常使用寿命完全可以和各类永久性建筑物的寿命相匹配。

　　7. Good durability: ALC board is a silicate material that does not have aging problems and is not easily weathered. It is a durable building material, and its normal service life can fully match the service life of various permanent buildings.

　　8、绿色环保：ALC板没有放射性，也没有有害物质溢出。加气混凝土防火板优越性：在生产过程中，没有污染和危险废物产生。使用时，也绝没有放射性物质和有害气体产生，即使在高温下和火灾中。各个独立的微气泡，使加气混凝土产品具有一定的抗渗性，可防止水和气体的渗透。

　　8. Green and environmentally friendly: ALC board has no radioactivity and no harmful substances overflow. The superiority of aerated concrete fireproof board: there is no pollution or hazardous waste generated during the production process. When used, there is absolutely no production of radioactive substances and harmful gases, even in high temperatures and fires. Each independent microbubble gives the aerated concrete product a certain degree of impermeability, which can prevent the penetration of water and gas.

　　9、经济实用：能增加使用面积，降低地基造价，缩短建设工期，减少暖气、空调成本，达到节能效果。

　　9. Economical and practical: It can increase the usable area, reduce the cost of foundation, shorten the construction period, reduce the cost of heating and air conditioning, and achieve energy-saving effects.

　　10、施工方便：加气混凝土产品尺寸准确、重量轻，可大大地减少人力物力投入。板材在安装时多采用干式施工法，工艺简便、效率高，可有效地缩短建设工期。

　　10. Convenient construction: Aerated concrete products have accurate dimensions and light weight, which can greatly reduce manpower and material resources investment. Dry construction method is often used for the installation of boards, which is simple in process, efficient, and can effectively shorten the construction period.

　　防火板的分类

　　Classification of fireproof boards

　　1、氯氧化镁防火板这种防火板是使用镁质胶凝为主要原材料来制作的，再在其中添加玻璃纤维布和一些轻质的保温材料来填充镁质胶凝，经过一系列的加工处理复合而成，它属于氯氧镁水泥类的制成品，但是环保性能比较强。

　　1. Magnesium oxychloride fireproof board is mainly made of magnesium binder as the raw material, and then filled with glass fiber cloth and some lightweight insulation materials to fill the magnesium binder. After a series of processing and composite, it belongs to the finished product of magnesium oxychloride cement, but has strong environmental performance.

　　2、防火石膏板材这种防火板主要是以石膏为主要原材料来进行的制作，这种板材的原材料的来源非常广，因此制作出来的种类也是比较多的，比如说双面贴纸石膏防火板、硅钙石膏纤维板等等，这些板材的内部含有结晶水，有较好的耐火性能，加工简便，常常被人们使用到吊顶等等的制作。

　　2. Fireproof gypsum board is mainly made from gypsum as the main raw material. The source of raw materials for this board is very wide, so there are also many types of boards produced, such as double-sided sticker gypsum fireproof board, silicon calcium gypsum fiber board, etc. These boards contain crystalline water inside, have good fire resistance, are easy to process, and are often used in the production of ceilings and other products.

　　3、矿棉板、玻璃棉板主要以矿棉、玻璃棉为隔热材料。其本身不燃、耐高温性能好、质轻，但不足之处有①短纤维对人体呼吸系统会造成危害，②板材强度差，③板材对火灾烟气蔓延的阻隔性能差，④装饰性差，⑤安装施工工作量大。因此，该种板材现已大部分演变成以无机粘结材料为基材，矿棉、玻璃棉作为增强材料的板材。

　　3. Mineral wool board and glass wool board mainly use mineral wool and glass wool as insulation materials. It is non flammable, has good high temperature resistance, and is lightweight, but its shortcomings include ① short fibers can cause harm to the human respiratory system, ② poor strength of the board, ③ poor barrier performance of the board against the spread of fire smoke, ④ poor decorative properties, and ⑤ large installation and construction workload. Therefore, most of this type of board has evolved into a board based on inorganic bonding materials and reinforced with mineral wool and glass wool.

　　4、水泥板水泥板材强度高，来源广泛。过去常用它作防火吊顶和隔墙，但其耐火性能较差，在火场中易炸裂穿孔、失去保护作用而使其应用受到一定限制。水泥混凝土构件的隔热、隔声性能好，可作为隔墙和屋面板。建材市场上陆续出现了纤维增强水泥板等改进品种，具有强度高、耐火性能好的优点，但韧性较差、碱度大、装饰效果较差。

　　4. Cement board has high strength and a wide range of sources. In the past, it was commonly used as a fireproof ceiling and partition wall, but its fire resistance performance was poor, and it was prone to explosion, perforation, and loss of protection in a fire, which limited its application to a certain extent. Cement concrete components have good thermal and sound insulation properties and can be used as partition walls and roof panels. Improved varieties such as fiber-reinforced cement boards have emerged in the building materials market, which have the advantages of high strength and good fire resistance, but have poor toughness, high alkalinity, and poor decorative effects.

　　5、珍珠岩板、漂珠板、蛭石板是以低碱度水泥为基材，珍珠岩、玻璃微珠、蛭石为加气填充材料，再添加一些助剂复合而制成的空心板材。具有自重轻、强度高、韧性好、防火隔热、施工方便等特点，可广泛应用于高层框架建筑物分室、分户、卫生间、厨房、通讯管等非承重部位。

　　5. Perlite board, floating bead board, and vermiculite board are hollow boards made by compounding low alkalinity cement as the base material, perlite, glass microspheres, and vermiculite as aerated filling materials, and adding some additives. It has the characteristics of light weight, high strength, good toughness, fire resistance and thermal insulation, and easy construction. It can be widely used in non load bearing parts such as compartments, households, bathrooms, kitchens, communication pipes, etc. of high-rise frame buildings.

　　6、硅酸钙纤维板是以石灰、硅酸盐及无机纤维增强材料为主要原料的建筑板材，具有质轻、强度高且隔热性、耐久性好、加工性能与施工性能优良等特点，主要用于制作天花板、隔墙以及作为钢柱、钢梁的防火保护材料。但板材强度和弯曲性能还有待提高。

　　6. Calcium silicate fiberboard is a building board mainly made of lime, silicate, and inorganic fiber reinforcement materials. It has the characteristics of light weight, high strength, thermal insulation, good durability, excellent processing and construction performance. It is mainly used to make ceilings, partition walls, and as a fire protection material for steel columns and beams. But the strength and bending performance of the board still need to be improved.

　　防火板多少钱一平米

　　How much is the fireproof board per square meter

　　这个不能一概而论，不同品牌，不同尺寸对价格都有影响，以下价格仅供参考：防火板常用的规格有：2135mm×915mm、2440mm×915mm、2440mm×1220mm，厚0.6-1.2mm。防火板一般都是按张来卖，从不按平米计算。价格多少与它的品质有关，从几十到几百价格不一，进口的防火板价格要更高一些；国产中等防火板一张的价格在100元左右。

　　This cannot be generalized. Different brands and sizes have an impact on prices. The following prices are for reference only: The commonly used specifications for fireproof boards are: 2135mm × 915mm, 2440mm × 915mm, 2440mm × 1220mm, with a thickness of 0.6-1.2mm. Fireproof boards are generally sold by sheet, not by square meter. The price is related to its quality, ranging from tens to hundreds of yuan. Imported fireproof boards are priced higher; The price of a domestically produced medium fireproof board is around 100 yuan.

　　防火板与阻燃板的区别

　　The difference between fireproof board and flame-retardant board

　　1、功效不同：?阻燃板是将阻燃剂渗入到实木薄单板中，起到抑制阻止板材燃烧，而防火板是通过在不易然烧的基材表层进行阻燃处理的装饰板材。

　　1. Different effects:? Flame retardant board is a decorative board that incorporates flame retardants into solid wood veneer to suppress and prevent the burning of the board, while fire-resistant board is a decorative board that undergoes flame retardant treatment on the surface of the substrate that is not easily burned.

　　2、基材不同：阻燃板的基材是实木的胶合板，而防火板是以矿棉、玻璃棉等为基材。

　　2. Different substrates: The substrate of flame retardant board is solid wood plywood, while the substrate of fireproof board is mineral wool, glass wool, etc.

　　3、板面不同：阻燃板的板面为薄木单板，表面较为粗糙，防火板是表面装饰耐火建材，其板面光滑平整、颜色艳丽、色彩多样，具有金属质感。

　　3. Different board surfaces: The board surface of flame-retardant board is thin wood veneer with a rough surface, while fireproof board is a surface decorative fire-resistant building material with a smooth and flat surface, bright colors, diverse colors, and a metallic texture.

　　4、用途不同：阻燃板常用于装修中的隔墙、隔断、吊顶等，防火板主要用于家庭装修的橱柜门板等家具中。

　　4. Different uses: Flame retardant boards are commonly used for partition walls, partitions, ceilings, etc. in decoration, while fireproof boards are mainly used for furniture such as cabinets and door panels in home decoration.

　　防火板与防火涂料的区别

　　The difference between fireproof board and fireproof coating

　　1、工期：防火板施工采用干式作业，板材连接固定简单，特别适合在工程为交叉施工时进行；涂料施工必须湿作业，影响其他工种进行。

　　1. Construction period: The fireproof board construction adopts dry operation, and the board connection and fixation are simple, especially suitable for cross construction in the project; Coating construction must be carried out wet, which affects the progress of other trades.

　　2、性能：由于防火板材均由工厂按严格工序进行生产，完全保证防火保护层的厚度；而防火涂料由于喷涂，涂刷受人为因素影响大，因此防火保护层厚度很难保证均匀和统一，既可能造成浪费也可能造成安全隐患。

　　2. Performance: Due to the strict production process of fireproof boards by the factory, the thickness of the fireproof protection layer is fully guaranteed; However, fireproof coatings are greatly affected by human factors during spraying and application, making it difficult to ensure uniform and consistent thickness of the fireproof protective layer, which may result in waste and safety hazards.

　　3、耐久性：由于防火板材均为无机材料，在自然界中的耐候性非常好，而且能够抵抗酸碱环境和一定的冲击，保护层不会有腐蚀和脱落现象，已有二十多年的使用历史；而防火涂料(尤其是厚涂型)则会因时间长久后涂料成分中胶结材料的失效而导致剥落，以至耐久性较差。

　　3. Durability: Due to the fact that fireproof boards are all inorganic materials, they have excellent weather resistance in nature and can resist acidic and alkaline environments as well as certain impacts. The protective layer will not corrode or peel off, and they have been in use for more than 20 years; However, fireproof coatings (especially thick coatings) may peel off due to the failure of bonding materials in the coating components over time, resulting in poor durability.

　　4、装饰性：采用防火板包覆，可以将防火材料与护面板合二为一，而且板面平整，装饰性好，表面可直接进行涂料施工，安装石材，瓷砖也非常方便；而涂料施工的话，必须在结构外面另加饰面板。

　　4. Decorative: Covered with fireproof board, the fireproof material and protective panel can be combined into one, and the surface is flat with good decorative properties. The surface can be directly coated, and the installation of stone and ceramic tiles is also very convenient; For coating construction, additional decorative panels must be added outside the structure.

　　5、造价：相对于防火涂料而言，防火板的单平米造价要高些，但是从综合的技术经济的角度来分析的话，防火板的价格优势仍然明显。首先，防火板性能稳定，耐久性好，使用寿命可长达30年以上，从而大大节约建筑进行长期维护，更新的费用，尤其是商业建筑，中途停业进行防火材料的替换，更新，必将造成重大的经济损失。

　　5. Cost: Compared to fireproof coatings, the cost per square meter of fireproof boards is higher, but from a comprehensive technical and economic perspective, the price advantage of fireproof boards is still significant. Firstly, the fireproof board has stable performance and good durability, with a service life of over 30 years, greatly saving the cost of long-term maintenance and renewal of buildings, especially commercial buildings. If the fireproof materials are replaced or renewed during the suspension, it will inevitably cause significant economic losses.

　　防火板选购技巧

　　Tips for selecting fireproof boards

　　1、查看防火板材外观首先你要看防火板材表面的颜色和肌理是否一致，有无色差和瑕疵，用手摸有没有凹凸不平、起泡的现象，优质防火板材应该是图案清晰透彻、无色差、表面平整光滑、耐磨的产品。

　　1. To check the appearance of fireproof boards, first you need to check whether the color and texture of the fireproof board surface are consistent, whether there are color differences and defects, and whether there are any unevenness or bubbles when touched by hand. High quality fireproof boards should have clear and transparent patterns, no color differences, smooth and wear-resistant surfaces.

　　2、选择品牌防火板材现在防火板材越来越受欢迎，所以市场上防火板材品牌也非常之多，其中不乏以次充好的产品。选购的时候，建议选择知名品牌的防火板材，虽然价格可能贵点，但是质量和售后比较有保证。

　　2. Choosing a brand of fireproof board: Nowadays, fireproof board is becoming increasingly popular, so there are also many brands of fireproof board on the market, among which there are many inferior products. When making a purchase, it is recommended to choose fire-resistant boards from well-known brands. Although the price may be higher, the quality and after-sales service are relatively guaranteed.

　　3、查看检测报告和燃烧等级我们在选购防火板材的时候，还要注意查看防火板材有无检测报告和出厂合格证等，如果没有，建议不要选购。仔细查看产品的检测报告，看产品各项性能指标是否合格，特别是注意查看检测报告中的产品燃烧等级，燃烧等级越高的产品耐火性越好。

　　3. When selecting fireproof boards, we should also pay attention to checking whether the fireproof boards have inspection reports and factory certificates. If not, it is recommended not to choose. Carefully review the product's testing report to see if all performance indicators are qualified, especially paying attention to the combustion level of the product in the testing report. Products with higher combustion levels have better fire resistance.

　　4、选择成型的防火板材而且不要选择防火板贴面，要选择购买成型的防火板材。因为如果由木工粘贴防火板，由于压制不过关，容易遇潮或霉变导致防火板起泡脱落。而专业生产的工厂一般配备了大型压床、高精密度裁板机等设备，可保证防火板达到不易起泡和变形的质量要求。

　　4. Choose molded fireproof boards and do not choose fireproof board veneers. Instead, choose to purchase molded fireproof boards. Because if the fireproof board is pasted by a carpenter, due to inadequate compression, it is easy to encounter moisture or mold, causing the fireproof board to bubble and fall off. Professional factories are generally equipped with large presses, high-precision cutting machines, and other equipment to ensure that the fireproof board meets the quality requirements of not easily foaming and deforming.

　　防火板的安装工艺

　　Installation process of fireproof board

　　1、直接黏贴直接胶粘法是防火板施工最常见的方法之一，是在已做木作或石膏板基层材料的墙体上直接上胶黏贴。常见有机基层板材料：澳松板、密度板、刨花板、细木工板和实木板。

　　1. Direct adhesive method is one of the most common methods for fireproof board construction, which involves directly applying adhesive to walls that have already been made of wooden or gypsum board base materials. Common organic base board materials: Australian pine board, density board, particleboard, particleboard, and solid wood board.

　　工艺流程：

　　Process flow:

　　a、首先用切割工具将耐火板裁切成所需要的尺寸，需注意耐火板每条边需多留6mm作为修边之用。

　　a、 Firstly, use cutting tools to cut the refractory board into the required size, paying attention to leaving an extra 6mm on each edge of the refractory board for trimming purposes.

　　b、用工具将基材表面与防火板的边缘砂磨平整。

　　b、 Use tools to sand and smooth the surface of the substrate and the edge of the fireproof board.

　　c、将适量的胶水均匀的刮开到防火板以及基材的背面。

　　c、 Scrape an appropriate amount of glue evenly onto the back of the fireproof board and substrate.

　　d、用滚轮或压力机加压以确保防火板粘贴到基板上面，之后做修边、清洁处理。

　　d、 Apply pressure with a roller or press to ensure that the fireproof board is adhered to the substrate, and then perform trimming and cleaning treatment.

　　2、干挂干挂结构主要是针对9mm的成品双面复合防火板和8mm抗倍特所采用的，承载龙骨为钢材或铝合金型材，用专用的标准扣片和可调节扣片将其固定到板材上进行安装的一种方式。

　　2. The dry hanging structure is mainly used for 9mm finished double-sided composite fireproof board and 8mm anti double special. The load-bearing keel is made of steel or aluminum alloy profiles, and it is fixed to the board with special standard and adjustable buckles for installation.

　　施工流程：龙骨排布、安装→铝合金干挂横龙骨排布、安装→铝合金可调挂件及普通挂件排布及安装→挂板→拼缝处理→清理

　　Construction Process: Keel Layout and Installation → Aluminum Alloy Dry Hanging Horizontal Keel Layout and Installation → Aluminum Alloy Adjustable Pendant and Ordinary Pendant Layout and Installation → Hanging Plate → Joint Processing → Cleaning

　　a、龙骨排布、安装安装龙骨前要对墙面进行测量，弹线定位。需要注意的是竖龙骨的间距要≤400mm，竖向龙骨的固定要用L型角码、M6膨胀螺栓及M自攻螺丝，固定点的间距≤600mm。

　　a、 Before arranging and installing the keel, it is necessary to measure the wall surface and mark the line for positioning. It should be noted that the spacing between vertical keels should be ≤ 400mm, and L-shaped corner brackets, M6 expansion bolts, and M self tapping screws should be used to fix the vertical keels. The spacing between fixing points should be ≤ 600mm.

　　b、铝合金干挂横龙骨的排布、安装同样的铝合金干挂横龙骨的间距要≤400mm，用M4自攻螺丝把横龙骨固定在竖龙骨上，间距≤400mm。

　　b、 The arrangement and installation of aluminum alloy dry hanging horizontal keels should have a spacing of ≤ 400mm. Use M4 self tapping screws to fix the horizontal keels to the vertical keels with a spacing of ≤ 400mm.

　　c、挂件的排布、安装把防火板背部朝上平放，根据图纸定位、画线、开孔、安装挂件。需要注意的是板上的螺丝开孔要小于螺丝的直径1mm，孔深大于螺丝长度1mm。最上部一排的挂件是可调试的，其它部分使用普通挂件，挂件的横竖间距要≤400mm。

　　c、 Arrange and install the pendant by placing the fireproof board with its back facing upwards, positioning, drawing lines, drilling, and installing the pendant according to the drawing. It should be noted that the screw holes on the board should be smaller than the diameter of the screw by 1mm, and the hole depth should be greater than the length of the screw by 1mm. The hanging parts in the top row are adjustable, while other parts use ordinary hanging parts, and the horizontal and vertical spacing of the hanging parts should be ≤ 400mm.

　　d、挂板挂板时要用玻璃吸盘吸住挂板，按照自下而上的顺序安装，整个墙面要控制在2m尺寸的高低差≤3mm。收口一般是通过吊顶压墙，顶部收边，底部收边板距离地面10mm可以用密封胶来填补。

　　d、 When hanging boards, glass suction cups should be used to hold the boards, and they should be installed in a bottom-up order. The height difference of the entire wall should be controlled within a 2m size of ≤ 3mm. The closing is usually done by pressing the ceiling against the wall, closing the top edge, and filling the bottom edge board with sealant at a distance of 10mm from the ground.

　　e、拼缝处理跟底部处理方法一样，板之间的拼缝可以使用密封胶来填补，也可以嵌装饰条或者利用企口自然拼缝，边缘则是使用美纹纸来保护。

　　e、 The joint treatment is the same as the bottom treatment method. The joints between the boards can be filled with sealant, or decorative strips can be embedded or natural joints can be made using tongue and groove. The edges are protected with masking paper.

　　防火板保养

　　Fireproof board maintenance

　　1、日常清洁日常清洁是对防火板最简单的保养了，其实板材本身就具有很强的耐污性能，但时间长以后总会难免粘上一些灰尘，特别是墙面和一些不常用到的台面，灰尘会比较多，这一类可以用鸡毛掸子或吸尘器进行清洁。对于一些其它的污点，一般的用湿抹布反复擦拭就能够清除，如果是顽固污渍则可以在抹布上蘸少许酒精进行擦拭。

　　1. Daily cleaning is the simplest maintenance for fireproof boards. In fact, the board itself has strong stain resistance, but over time, it is inevitable that some dust will stick to it, especially on walls and some infrequently used countertops. This type of dust can be cleaned with a feather duster or vacuum cleaner. For some other stains, they can generally be removed by repeatedly wiping with a damp cloth. If they are stubborn stains, you can dip a little alcohol on the cloth for wiping.

　　2、打蜡打蜡是家具最常见的保养，如果有条件的话，在防火板上也可以进行，在打蜡保养时选择专业用在家具上的光蜡就可以。在上蜡之前先保持板面干净，最好在彻底清洁之后在进行上蜡，上蜡过后等待自然风干在使用。

　　2. Waxing is the most common maintenance for furniture, and if possible, it can also be done on fireproof boards. When waxing and maintenance, choose professional light wax used on furniture. Before waxing, keep the surface clean. It is best to thoroughly clean it before waxing. After waxing, wait for natural air drying before use.

　　3、防潮防火板虽然本身具有很好的防水防潮性能，但毕竟是贴面板，而且还考虑到基材的质量。所以在日常生活中也需要注意使用环境的干燥，特别是厨房部分需要勤打扫。还有就是要避免与一些强酸碱液体接触。这样才能有效的提高防火板的使用寿命。

　　3. Although moisture-proof and fire-resistant boards have good waterproof and moisture-proof properties, they are still laminated panels, and the quality of the substrate is also considered. So in daily life, it is also necessary to pay attention to the dryness of the usage environment, especially the kitchen part that needs to be cleaned frequently. Also, it is important to avoid contact with strong acidic and alkaline liquids. This can effectively improve the service life of fireproof boards.
