after the fire resistance of fire-proof board is popular, it is widely used in kitchens, furniture, external walls and other places in decoration. There are many kinds of fire-proof board materials. What are the characteristics of so many kinds of fire-proof boards? What are they made of? Is it harmful? Xiaobian simply sorted out the relevant knowledge about the types of fire boards. Let's take a look:

1. Types of fire boards-decorative fire boards

are composed of thin aluminum layers and plastic layers, which are divided into single-sided decorative fire boards and double-sided decorative fire boards, and the thickness is generally about 3-5 mm. Decorative fireproof board is good in decoration, and is used for image walls, display cabinets, kitchen and bathroom ceilings, etc. When purchasing decorative fire-proof board, use vernier caliper to measure whether the thickness meets the requirements, and then prepare magnet to test whether it is iron or aluminum.

2. Type of fire-proof board-magnesium oxychloride fire-proof board

This kind of fire-proof board is made of magnesium gel as the main raw material, and then glass fiber cloth and some light insulation materials are added to it to fill the magnesium gel, which is compounded through a series of processing. It belongs to magnesium oxychloride cement products, but it has strong environmental protection performance.

3. Types of fire-proof boards-Fire-proof gypsum boards

Since the fire-proof performance of gypsum has been widely accepted, fire-proof boards based on gypsum have developed rapidly. The main components of the board are incombustible and contain crystal water, which has good fire resistance and can be used as partition walls, suspended ceilings and roof panels. The raw material source of the plate is rich, which is convenient for factory stereotypes production. In use, it has a light weight, which can reduce the bearing capacity of buildings, and is easy to process, saw and plane, convenient to construct and good in decoration, but its flexural performance is poor. There are many factors that affect the fire resistance of gypsum board, such as composition, type of board, type of keel, thickness of board, presence or absence of filler in air layer, and assembly method.

4. Types of fire protection boards-mineral wool board and glass wool board

Mineral wool and glass wool are mainly used as heat insulation materials. It is incombustible, high temperature resistant and light in weight, but it has some disadvantages, such as ① short fiber will do harm to human respiratory system, ② poor strength of the board, ③ poor barrier performance of the board to the spread of fire smoke, ④ poor decoration, and ⑤ heavy workload of installation and construction. Therefore, this kind of board has mostly evolved into a board with inorganic bonding materials as the base material and mineral wool and glass wool as the reinforcing materials.

5. Types of fire boards-Composite fire boards

Composite fire boards are aluminum products, so they are called composite fire boards because they are fastened on the keel. Composite fire boards are generally 1.4 mm-1.8 mm thick, and there are strips, squares, diamonds, etc. Generally, there are two places to install aluminum button ceiling when decorating, one is the bathroom and the other is the kitchen. The ceiling of the bathroom should be hollowed out. The kitchen flower board should be flat. When purchasing composite fire-proof board, be careful to use stainless iron as fake, and you can use magnets to verify it.

The above are the types of fire boards compiled by Xiaobian, and there may be some shortcomings. Xiaobian will stop here today, hoping to give you some help. If you want to know more, please pay attention to us!
