concept
Insulation composite maintenance sheet made of color coated steel sheet or other panel and bottom plate and heat insulating core material through adhesive (or foaming).
Composite methods usually have explosive composites, explosive rolling composites, rolling composites, and the like. Composite materials can be divided into composite plates, composite pipes, composite rods and the like. Mainly used in anti-corrosion, pressure vessel manufacturing, electric construction, petrochemical, pharmaceutical, light industry, automotive and other industries.
Composite materials can be classified into composite plates, composite pipes, composite bars, and the like according to their appearance.
use
1. Industrial plant, warehouse
2. Cold storage, box packaging
3. Light steel residential, original building mezzanine
4. Mobile board room
5. Various purification rooms, air conditioning rooms, etc.
advantage
1. Light weight, about 10kg ~ 14kg / square meter, equivalent to 1 / 30 of the brick wall;
2. Thermal insulation, good suction and sealing performance;
3. Convenient construction, flexible and quick installation, and the construction period can be shortened by more than 40%;
4. Bright color, beautiful appearance, no need to decorate the surface;
5. High strength, can be used for maintenance structure, load-bearing structure, bending and compression resistance, general houses can be used without beams and columns.
Main board:
1.Surface/floor (color coated board, galvanized sheet, stainless steel sheet, aluminum foil paper, PVC, plywood, etc.)
1.1 Introduction of various sheet properties
(1) color coated board
The substrate is hot-dip galvanized or galvanized sheet, and the galvanized substrate is also used, and the surface lacquer is bent without falling off;
The color steel plate used for composite board is generally two-coat one-bake (two-coat one), and two-coat two-bake (two-coat two) or there are quality problems such as loose edge, middle loose, leaky coating, large jagged edge, serious Ellipse, jagged, etc. cannot be used to produce composite panels.
(2) galvanized sheet
Bad bonding is sometimes not handled well and needs to be handled.
(3) Stainless steel plate
Good corrosion resistance, toughness is difficult to process; bonding effect is sometimes not good, need to be treated.
(4) Aluminum foil paper
Reinforced aluminum foil is a composite material with glass fiber reinforced ribs between aluminum foil and kraft paper. It has the functional characteristics of flame retardant and fireproof, and is beautiful and durable. It is an ideal matching insulation layer for new generation insulation, heat insulation and sound insulation. .
(5) PVC
The main raw material of PVC foam board is polyvinyl chloride (PVC), which is characterized by smooth surface, light weight, flame retardant, moisture-proof, soundproof, anti-corrosion, easy to cut, good weather resistance, acid and alkali resistance and easy cleaning.
(6) Plywood
Because of the limited length of each piece, the compactness of the plywood is not very good, and the crack phenomenon is difficult to solve.
Main core material:
2. Core material (mainly: EPS, rock wool, glass wool, flame retardant honeycomb panel, polyurethane, etc.)
2.1 Introduction of various core materials
(1) Foam board
From the expandable polystyrene (EPS) particles as raw materials, the shape is like fertilizer particles, pre-expanded by heating, into larger particles like white pearls, and then heated and pressed in a mold to form a fine closed-cell structure. Foam sheet.
(2) Polyurethane
High energy saving performance
The material with excellent fireproof and thermal insulation properties, the polyurethane bulk density used for composite panels is generally 30 kg - 40 kg.
(2) Rock wool board
It is made of basalt stone as the main raw material. After high temperature melting, the inorganic fiber is made from high-speed centrifugal equipment. At the same time, a certain proportion of binder is uniformly added to bake into a large plate. According to the production needs, it is cut into rock wool strip, and rock wool is non-combustible. Body, fire performance is good.
(4) Glass wool
It is a kind of heat-insulating material with light weight, heat resistance, elasticity and energy. It is widely used in chemical, pharmaceutical, factory, heavy industry machinery and equipment, construction, vehicle and ship, and aerospace. It is an ideal heat-dissipating, fire-proof and sound-absorbing material.
(5) Flame retardant paper honeycomb panel
It is a national B1 fireproof material, which has the advantages of good flame retardancy, good compressive strength, no carbonization, no toxic substances, and complete recycling and reuse of waste. It is a core of polystyrene, polyurethane and rock wool. An ideal substitute for wood.
(6) Polyurethane is a kind of material with excellent fireproof and heat preservation performance. The weight of polyurethane board used for composite board is generally 30-40 kg.
As a new heating solution, Far Infrared Heaters has many advantages compared to traditional heating methods like air pump, gas or oil. It is clean and has a surprisingly high conversion rate which can up to 98% in theory. Farther more, the far infrared itself is benefit for our bodies and well-being. It is easy for installation and need no maintenance at all.
