Fireproof board, also known as refractory board, the scientific name is thermosetting resin impregnated paper high-pressure laminated board, the English abbreviation is HPL (Decorative high-pressure laminate) is a refractory building material for surface decoration, with rich surface color, texture and special physical properties.

Fireproof panels are widely used in interior decoration, furniture, kitchen cabinets, laboratory countertops, exterior walls and other fields.

Fireproof board is a refractory building material for surface decoration. Fireproof board is made of base paper (titanium powder paper, kraft paper) after the impregnation process of melamine and phenolic resin, and after a high temperature and high pressure environment.

1. Mineral wool board, glass wool board: Mainly mineral wool and glass wool are used as insulation materials.It is non-combustible, has good high temperature resistance and light weight, but its shortcomings are: ① Staple fibers can cause harm to the human respiratory system; ②The strength of the sheet is poor;③The sheet has poor barrier properties to the spread of fire smoke;差The decoration is poor, and the installation and construction workload is large.Therefore, most of this kind of sheet has now evolved into a sheet with inorganic adhesive materials as the substrate and mineral wool and glass wool as the reinforcing materials.

2. Cement board: 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 was poor, and it was easy to explode and perforate in a fire, and its application was limited by the loss of protection.Cement concrete components have good heat insulation and sound insulation properties, and can be used as partition walls and roof panels.Improved varieties such as fiber-reinforced cement slabs have appeared in the building materials market one after another, which have the advantages of high strength and good fire resistance, but have poor toughness, high alkalinity, and poor decorative effects.

3. Perlite board, bleaching bead board, vermiculite board: It is a hollow board made of low-alkalinity cement as the substrate, perlite, glass beads, and vermiculite as the aerated filling material, and then some additives are added to make a composite.It has the characteristics of light weight, high strength, good toughness, fireproof and heat insulation, and convenient construction. It can be widely used in non-load-bearing parts such as sub-rooms, sub-households, toilets, kitchens, and communication pipes of high-rise frame buildings.

4. Fireproof gypsum board: Since the fireproof properties of gypsum have been widely accepted, fireproof boards based on gypsum have developed rapidly.The main components of the sheet are non-combustible and contain crystalline water. It has good fire resistance and can be used as partition walls, ceilings and roof panels.The sheet has a rich source of raw materials, which is convenient for factory stereotyped production.In use, it has a lighter weight, can reduce the load-bearing of the building, and is easy to process, sawing and planing, easy to construct, and good decoration, but its folding resistance is poor.There are many factors that affect the fire resistance of gypsum board, such as the composition, the type of board, the type of keel, the thickness of the board, the presence or absence of fillers in the air layer, and the assembly method.There have been new varieties of silicon-calcium gypsum fiberboard, double-sided sticker gypsum fireproof board, etc.

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

6. Magnesium oxychloride fireproof board: It belongs to magnesium oxychloride cement products. It is composed of magnesia gelling material as the main body, glass fiber cloth as the reinforcing material, and lightweight thermal insulation material as the filling material. It can meet the requirements of non-combustibility and is a new type of environmentally friendly board.

Good processing performance, to meet the requirements of different production processes. Cured oil filter paper (180 ° C for 10 minutes, buy fast curing oil filter paper 160 ° C for 3 minutes (low consumption), use synthetic fiber and high-performance resin to produce filter paper to meet the requirements of the new generation.
Turbocharged direct injection mode is required.
Warm oil (200-500 hours) corrosion resistance, long service life, lightweight, cost-effective synthetic fiber oil filter material has the characteristics of light weight, high efficiency, high DHC, and long service life.

Features:
PET spunbonded non-woven fabric, PEB meltblown non-woven fabric, ultrasonic spot welding filter paper or bonding process forming, rotating bonding layer as a protective layer, with oil and water layer, retention capacity and filtration performance, to meet the requirements of wood pulp paper comprehensively, continuously improve the physical index requirements of dust removal of synthetic filter material and folds, and determine the performance of filtration effect.
