There are various types of building materials, which can be divided into four categories based on their combustion performance, namely: non combustible materials (Class A), non combustible materials (Class B, Class B), combustible materials (Class C), and combustible materials (Class D). The fireproof board countertop material should be basically non combustible material. Non combustible materials (also known as A-grade materials) can only be classified as non combustible materials if they meet the following conditions when conducting non combustible tests according to GB/T5464-85

(1)由于材料嫩烧引起炉内平均温升不超过50摄氏度

(1) Due to the tender burning of materials, the average temperature rise in the furnace does not exceed 50 degrees Celsius

(2)试样平均持续嫌烧时间不超过

(2) The average continuous burning time of the sample shall not exceed

(3)试样平均质量损失率不超过

(3) The average mass loss rate of the sample shall not exceed

一些无机板材(如氧镁水泥板).虽然本身不会燃烧，但在火灾的高沮作用下.极易分解、炸裂失去结构强度，有的还会释放出大有毒气体。因此，这些板材仍不能用作防火板台面材。这就是我们防火板台面材的作为防火使用的基本要求所在。

Some inorganic boards (such as magnesium oxide cement boards), although they do not burn themselves, are prone to decomposition, cracking, and loss of structural strength under the high pressure of fire. Some may also release large and most toxic gases. Therefore, these boards cannot still be used as fire-resistant tabletop materials. This is the basic requirement for our fireproof board countertop material to be used as a fireproof material.

Key points to remember in the construction of fireproof board countertops: elegant walnut fireproof board

(1)薄型防火涂料可按装饰要求和涂料性质选择喷涂、刷涂或辊涂等施工方式。

(1) Thin fire-resistant coatings can be applied by spraying, brushing, or roller coating according to decoration requirements and coating properties.

(2)薄型防火涂料每次喷涂厚度不应超过丹麦枫木防火板2.5mm,超薄型涂料每次涂层不应超过0.5mm.须在前一遍干操后方可进行后一遍施工。

(2) The thickness of each spray of thin fire-resistant coating should not exceed 2.5mm for Danish maple fire-resistant board, and the thickness of each coat of ultra-thin coating should not exceed 0.5mm. The construction of the next coat must be carried out after the previous dry operation.

(3)厚型防火涂料可选用喷涂或手工涂抹施工。

(3) Thick fireproof coatings can be applied by spraying or manual application.

卡布奇诺防火板 (4)厚型防火涂料宜用低速搅拌机搅羽织铜防火板拌，搅拌时间不宜过长，搅拌均匀即可，以免涂料中轻质骨料被过度粉碎影响涂层质量。

Cappuccino fireproof board (4) thick fireproof coating should be mixed with a low-speed mixer and woven copper fireproof board. The mixing time should not be too long, and it should be evenly mixed to avoid excessive crushing of lightweight aggregates in the coating and affecting the quality of the coating.

(5)厚型防火涂料每遏涂抹厚度圈线铜防火板宜为5 四季榆木防火板- 10mm，必须在前一道涂层基本干操或固化后方可进行后一道施工。

(5) The thickness of the thick fireproof coating should be 10mm for each round of copper fireproof board applied, and the next layer of construction can only be carried out after the previous layer of coating is basically dry or cured.

(6)水泥系厚型防火涂料在天气极度干燥和阳光直射环境下应采取必要养护措施。风化灰木层防火板

(6) Necessary curing measures should be taken for cement based thick fireproof coatings in extremely dry weather and direct sunlight environments. Weathered gray wood layer fireproof board

(7)防火涂料搅拌好后应及时用完，超过其规定使用期不得使用。

(7) After mixing, the fireproof coating should be used up in a timely manner, and should not be used beyond its specified usage period.

(8)防火涂层的厚度应符合设计要求，施工时应随时检测涂层厚度。

(8) The thickness of the fireproof coating should meet the design requirements, and the coating thickness should be checked at any time during construction.
