Six categories of fireproof and waterproof boards Tips for purchasing fireproof and waterproof boards

Fireproof and waterproof boards are very popular in the current construction industry, especially in factory workshops of some precision electronic instruments, as well as in some areas that require special fireproofing and waterproofing, and even in many homes now. Using such fireproof and waterproof boards, fireproof and waterproof boards, as the name suggests, its main function is to be fireproof and waterproof. However, I think everyone still doesn’t know much about the classification of fireproof and waterproof boards and how to choose fireproof and waterproof boards. Below we will Let’s take a look together.

Six categories of fireproof and waterproof boards

1. Mineral wool board and glass wool board: Mineral wool and glass wool are mainly used as thermal insulation materials. It is non-combustible, has good high-temperature resistance, and is lightweight. However, its shortcomings are: 1. Short fibers can cause harm to the human respiratory system, 2. The strength of the board is poor, 3. The board has poor barrier properties against the spread of fire smoke, 4. The decorative properties are poor, and 5. The installation and construction workload is heavy. Therefore, most of this kind of boards have evolved into boards with inorganic bonding materials as the base material and mineral wool and glass wool as reinforcing materials.

2. Cement board: Cement board has high strength and comes from a wide range of sources. In the past, it was often used as fireproof ceilings and partition walls, but its fire resistance is poor. It is easy to burst and perforate in fire scenes, and loses its protective effect, which limits its application. Cement concrete components have good heat and sound insulation properties and can be used as partition walls and roof panels. Improved varieties such as fiber-reinforced cement, fireproof board, and board have gradually appeared in the building materials market. They have the advantages of high strength and good fire resistance, but have poor toughness, high alkalinity, and poor decorative effect.

3. Perlite board, floating bead board, vermiculite board: they are based on low-alkalinity cement, perlite, glass beads, and vermiculite are aerated filling materials, and some additives are added Hollow panels made of composite materials. It has the characteristics of light weight, high strength, good toughness, fire protection and heat insulation, and convenient construction. It can be widely used in non-load-bearing parts such as sub-rooms, sub-divisions, bathrooms, kitchens, communication pipes and other high-rise frame buildings.

4. Fireproof gypsum boards: Since the fireproof properties of gypsum have been widely accepted, fireproof boards based on gypsum have developed rapidly. The main component of this board is non-combustible and contains crystal water. It has good fire resistance and can be used as partition walls, suspended ceilings and roof panels. The raw materials of this board are rich in sources and are convenient for factory-specific production. In use, it has a light weight, which can reduce the building load-bearing, is easy to process, can be sawed and planed, is convenient for construction, and has good decorative properties, but its bending resistance is poor. There are many factors that affect the fire resistance of gypsum boards, such as composition, type of board, type of keel, thickness of the board, presence or absence of fillers in the air layer, assembly method, etc. In recent years, new varieties such as calcium silicate gypsum fiber? Fireproof board? Dimensional board and double-sided sticker gypsum fireproof board have appeared.

5. Calcium silicate fiber board: It is a building board made of lime, silicate and inorganic fiber reinforced materials as the main raw materials. It has light weight, high strength, heat insulation, good durability and processing performance. It has the characteristics of excellent construction performance and is mainly used to make ceilings, partition walls and as fire protection materials for steel columns and steel beams. However, the strength and bending performance of the plate need to be improved.

6. Magnesium oxychloride fireproof board: It is a magnesium oxychloride cement product. It is composed of magnesium cementitious material as the main body, glass fiber cloth as the reinforcing material, and lightweight insulation material as the filler. It can meet the requirements of non-combustibility and is a new type of environmentally friendly board.

What are the specifications of fireproof and waterproof boards?

The application of fireproof boards is widely used in kitchen cabinet countertops and cabinet door veneer decoration in home decoration. It can withstand high temperatures and open flames. The general profile specifications are (length × width) 1220mm × 2440, and the thickness ranges from 0.6m?m, 0.8?mm, 1.0rnm, 1.2?mm. A few varieties with better texture and color are mostly above 0.8rnm, and the prices are therefore different. .

Tips for purchasing fireproof and waterproof boards

Inferior quality fireproof and waterproof boards generally have the following characteristics: uneven color, easy to break and burst, and simple colors. In addition, it The heat resistance, acid and alkali resistance, and wear resistance are also correspondingly poor.

When purchasing, you should also be careful not to be deceived by merchants and use melamine boards instead of fireproof boards. Melamine boards (commonly known as double-decorated panels) are one-time molded boards. This kind of board is made by soaking paper printed with color or imitation wood grain in melamine transparent resin, and then attaching it to the surface of the base material and hot pressing it. ?The reference price of fireproof and waterproof boards. The current market price of fireproof and waterproof boards is between 40 and 300 yuan/sheet. In modern home decoration, fireproof and waterproof boards are mainly used in kitchen cabinets and are rarely used in other aspects.
