General knowledge of class a fireproofing materials
Nowadays, the grades of fireproofing materials are mainly as follows:
Class A: non combustible building materials, hardly burning materials.
Class A1: non flammable, not open flames.
Class A fire-proof insulation board does not melt and soften at high temperature. It has low smoke volume, no scattering flame, flame penetration resistance, and reaches the national Class A fire-proof standard. It also has excellent thermal insulation and energy-saving function. It integrates excellent fire-proof function with outstanding energy-saving function.
Class a fireproofing materials include rock wool board, inorganic thermal insulation mortar, glass panel, foam glass plate, foam ceramic plate, sand aerated concrete, ceramsite concrete, foamed cement, microbead board.
rock wool board
Basalt and other natural ores are used as main raw materials. Rock wool board is melted into fibers at high temperature, participated in proper amount of binder and solidified.
Features: good air permeability and no condensation reaction; outstanding sound insulation function; outstanding thermal and chemical stability; reliable hydrophobicity; outstanding mechanical strength; easy construction.
Inorganic thermal insulation mortar
It is a new type of heat preservation and energy saving mortar material for building interior and exterior wall painting. It uses inorganic light heat preservation particles with small thermal conductivity as light aggregate, and then mixes with cementitious materials (such as cement, rubber powder), anti-cracking materials (such as short-cut fibers), thickeners and filling materials (such as fly ash, gypsum, etc.). mortar
1. Selected imported renewable Lianshang rubber powder, inorganic cementitious materials, high-quality orthopedics and assistants with water retention, addition, livestock modification, crack resistance and other functions are pre-mixed and dried.
2. all kinds of insulation materials have excellent cohesive force.
3. outstanding flexibility, water resistance, weatherability.
4. on-site direct addition of water harmonic operation, convenient operation.
5., safety and environmental protection conform to industrial policies.
Glass wool board
It is a kind of elastic fiberglass product made of glass fibers with a diameter of only a few microns. It is made by centrifugal technology, melted glass fibers and thermosetting resins as the main environmental protection formulation binder. It is suitable for filling materials in dry hanging external wall system.
It is a new type of inorganic thermal insulation material with uniform and independent airtight pore structure, which is made of glass as the main raw material, mixed with appropriate foaming agent and processed by heating roasting and annealing and cooling in high temperature tunnel kiln.
1. the appearance density is small, the intensity is high, its outward strength is in 0.5MPa ~ 1.0MPa.
2. the thermal insulation function is good, and its thermal conductivity is about 0.05W/m. K.
3. low water absorption.
4. freezing and thawing resistance. Good durability. It can reach the same life as the building.
5. the expansion coefficient is low, the scale stability is good, and the concrete is near the expansion coefficient of mortar.
6., it is not easy to be destroyed by rats, insects and other animals.
