The classification of fire prevention board

Classification of fire boards

First, mineral wool board, glass wool board: mainly mineral wool, glass wool as heat insulation materials. Its non-combustible, high temperature resistance is good, light weight, but the shortcomings are:

Short fiber can cause harm to human respiratory system;

Plank strength is poor;

The barrier performance of the sheet on the spread of fire smoke is poor.

Poor decoration;

The installation and construction workload is large.

Therefore, most of the plate has evolved into inorganic binder material as the base material, mineral wool, glass wool as the reinforcement of the plate.

Two, cement board: cement plate strength is high, the source is wide. In the past, it is commonly used as a fireproof ceiling and partition, but its fire performance is poor, in the fire prone to crack perforation, loss of protection and its application is limited to a certain extent. Cement concrete member has good heat insulation and sound insulation performance, and can be used as partition wall and roof board. The improvement breed such as fiber reinforced cement board appeared in succession on building materials market, have the advantage of high intensity, good fireproof performance, but toughness is poorer, basicity is big, adornment effect is poorer.

Three, perlite board, floating bead board, vermiculite stone: it is a hollow plate made of low alkalinity cement as the base material, perlite, glass beads, vermiculite as the aerated filling material, and then add some additives. With light weight, high strength, good toughness, fire insulation, convenient construction and other characteristics, can be widely used in high-rise frame building room, household, bathroom, kitchen, communication pipe and other non-load-bearing parts.

Four, fire prevention gypsum plate: since the fire prevention performance of gypsum is widely accepted, the fire prevention plate that takes gypsum as the base material develops very fast. The main composition of the plate is non-combustible and contains crystal water, and the fire resistance is good. It can be used as partition wall, ceiling and roof board, etc. The material source of the plate is abundant, which is convenient for the factory to produce. In use, its weight is light, can reduce the building load bearing, and processing is easy, sawing can be planed, convenient construction, good decoration, but its anti bending performance is poor. There are many factors affecting fire resistance of gypsum board, such as the type of composition, board, keel type, thickness of board, air layer without filler, assembling means, etc.

Five, calcium silicate fiberboard: is lime, silicate and inorganic fiber reinforced materials as the main raw materials of the building board, with light weight, high strength and thermal insulation, good durability, processing performance and construction performance is excellent and other characteristics, mainly used for the production of ceiling, partition and as steel column, steel beam fire protection materials. However, the strength and bending property of the plate are still to be improved.

Six, magnesium crystal fire board: also known as glass magnesium board, magnesium oxide board, magnesite board magnesium quality board. Magnesium crystal plate is widely used in shopping mall, hotel, entertainment, hotels, Banks, hospitals, supermarkets, office buildings, villas villa and family homes, and other indoor decoration of partition, suspended ceiling, metope substrates, such as all sorts of modelling, suitable for wall, fire prevention board, moistureproof board, alternative woodiness dado, furniture, plywood do fire door splint, equipment box packaging and other fields. The surface has good coloration, high strength, easy to bend and toughness, can be nailed, sawed, sticky, convenient construction.
