Abstract: color steel composite plate is a color steel plate that combines surface materials and core materials.
It is mainly used in industrial plants, warehouses, cold storages, box packaging, light steel houses, air conditioning rooms and other fields.
Its surface materials mainly include color coated plate, galvanized plate, stainless steel plate, aluminum foil paperboard, etc. its core materials mainly include EPS, rock wool, glass wool, flame retardant paper honeycomb plate, polyurethane, etc.
The service life of color steel composite plate is long, and it can be used for about 8-20 years under normal conditions.
Color steel composite plate board is a thermal insulation composite maintenance board composed of color coated steel plate or other panel and bottom plate and thermal insulation core material through binder (or foaming). Its materials are divided into surface material and core material:
(1) Color coated plate
The base plate is hot-dip galvanized or aluminized zinc plate, or electro galvanized base plate, and the surface paint will not fall off after bending;
Color Steel Composite Plate is generally coated and baked (coated and baked), and the two coated and baked (coated and baked) or has quality problems, such as serious loose edge, loose center in the middle, missing coating, large sawtooth edge, serious ellipse, uneven, etc.
it can not be used for the production of composite plate.
(2) Galvanized sheet
The bonding effect is not good, sometimes it is not handled very well, and it needs to be handled.
(3) Stainless steel plate
Good corrosion resistance, high toughness and difficult to process; Sometimes the bonding effect is not good and needs to be treated.
(4) Aluminum foil paper
Reinforced aluminum foil is a kind of composite material with glass fiber reinforced rib sandwiched between aluminum foil and kraft paper.
It has the functional characteristics of flame retardant and fire prevention, and is beautiful and durable.
It is an ideal supporting insulation layer for a new generation of thermal insulation, heat insulation and sound insulation.
The main raw material of PVC foam board is polyvinyl chloride (PVC), which is characterized by flat and beautiful surface, light weight, flame retardant, moisture-proof, sound insulation, anti-corrosion, easy cutting, good weather resistance, acid and alkali resistance and convenient cleaning.
Because the length of each plywood is limited, the compact effect is not very good, and the crack phenomenon is difficult to solve.
(1) foam board
The polystyrene (EPS) particles are used as raw materials, shaped like chemical fertilizer granules, preheated by heating, made into larger particles of white pearls, and then heated and pressed in moulds to form foam plastic plates with fine closed cell structure.
It is a material with excellent fireproof and thermal insulation performance. The unit weight of polyurethane used for composite board is generally 30kg-40kg.
(3) Rock wool board
It takes basalt as the main raw material. After melting at high temperature, it is made into inorganic fiber by high-speed centrifugal equipment.
At the same time, it is evenly added with a certain proportion of adhesive to bake into a large plate. It is cut into rock wool strips according to production needs. Rock wool is a non combustible body with good fire resistance.
(4) Glass wool
It is a kind of light, heat-resistant, elastic and non combustible thermal insulation material. It is widely used in chemical industry, medicine, factories, heavy industrial machinery and equipment, construction, vehicles and ships and aerospace.
It is an ideal heat breaking, fire prevention and sound-absorbing material.
(5) Flame retardant paper honeycomb board
It is a national grade B1 fireproof material, which has the advantages of good flame retardancy, good compressive strength, only carbonization and no combustion, no toxic substances, and waste can be completely recycled.
It is an ideal substitute for core materials such as polystyrene, polyurethane and rock wool.
The reason why color steel composite plate is widely used is that it has many advantages. Among them, long service life and durability are its major advantages. How long is the service life of color steel plate?
According to the types of color plates commonly used in China and the environment for normal use, the service life of color coated steel plates for construction can generally be as follows:
decorative Service Life: 8 ~ 12 years; Overhaul service life: 12 ~ 20 years; Ultimate service life: more than 20 years.
Of course, the specific service life is also related to the environment, the quality of materials used and the way of maintenance.
