Mineral wool is the industrial waste slag as main raw materials by melting, cotton like insulation material made by injection method and centrifugal method: cotton is a natural rock as raw material is made of mineral wool. The commonly used rock such as Xuan Wuyan, diabase, amphibolite etc..Mineral wool characteristics: mineral cotton and products is a high-quality insulation materials, has more than 100 years of production and application history. The utility model has the advantages of light weight, heat preservation, heat insulation, sound absorption, good chemical stability, no burning and corrosion resistance, abundant raw material sources and low cost:

Q:What are the types of insulation materials used in pipes and equipment?

Mineral wool is the industrial waste slag as main raw materials by melting, cotton like insulation material made by injection method and centrifugal method: cotton is a natural rock as raw material is made of mineral wool. The commonly used rock such as Xuan Wuyan, diabase, amphibolite etc..Mineral wool characteristics: mineral cotton and products is a high-quality insulation materials, has more than 100 years of production and application history. The utility model has the advantages of light weight, heat preservation, heat insulation, sound absorption, good chemical stability, no burning and corrosion resistance, abundant raw material sources and low cost:Main use of mineral cotton: its products are mainly used in the walls of dry buildings, roof, ceiling and other insulation, insulation and sound absorption, but also made of waterproof felt and pipe sleeve.

Q:What are the building thermal insulation materials in general?

Commonly used building thermal insulation materials are benzene board, Extrusion board, polyurethane spraying, etc..

Q:What are the exterior wall insulation materials?

Polyurethane, this material is the best performance of other materials in the insulation cotton, the use of more, such as refrigerators, cold, and so on. The thermal conductivity is much lower than that of the benzene and extrusion panels, and the price is much higher.

Q:What is mineral fiber cotton? Yes, it's insulation.

Mineral wool, glass wool, rock wool, slag including cotton (cotton), aluminum silicate fiber, alumina fiber, can be classified according to the production process of products use or use temperature etc..

Q:What material is fast heated and kept warm?

The gap between the heating tube and the aluminum tube is filled with a heat conductive insulating elastic rubber, so that the heat can be rapidly transferred to the aluminum tube.Conductive heat insulation elastic rubber adopts silicon rubber base material, boron nitride, alumina and other ceramic particles as filler, the heat conduction effect is very good. Under the same conditions, the thermal impedance is smaller than that of other thermal conductive materials. Having a soft, clean, no pollution, high insulation and radiation characteristics of glass fiber provides good mechanical properties to reinforcement, anti piercing, shear resistance, tear resistance, with conductive pressure-sensitive adhesive.

Q:What materials should be used for building energy saving? Why?

Glass wool is second kinds of products of mineral wool, with silica sand, limestone, fluorite and other minerals as the main raw material, by melting method and centrifugal method, using flame or high energy gas blowing process, the molten glass liquid made of inorganic fiber. Glass wool products have good thermal insulation, heat insulation, sound absorption, non burning, corrosion resistance and other properties. They are widely used in building, piping, storage tanks, boilers, aircraft, ships and other parts of the insulation, heat insulation and sound absorption.

Q:Advantages of exterior wall energy saving and environmental protection heat insulation coating

1, rock wool board, inorganic refractory class A, thermal conductivity of 0.041-0.045, fire retardant, moisture absorption, insulation effect is poor;2, inorganic active insulation refractory grade A, thermal conductivity of 0.050-0.055 fireproof insulation effect is good, the construction is simple (no mesh, mortar etc.), and buildings with life, water resistant anti cracking hollowing;3, ceramic insulation board, inorganic refractory grade A, thermal conductivity 0.08-0.10, fire retardant, non absorbent, easy construction, durable use;

Q:What are the properties of fire-resistant coatings for steel structures?

Ultra thin structure fire retardant coating refers to the coating thickness of 3mm (including 3 mm) less than, decorative effect is good, high temperature can expand foaming, fire-resistant limit is generally less than 2 H steel structure fire retardant coating. This kind of fire retardant coatings for steel structures is generally solvent system, bonding strength, weathering has good water resistance, good leveling, good decorative features such as superior; subjected to fire slow expansion foam fire insulation layer to form a dense solid, the fireproof layer has a strong impact resistance, the temperature rise of steel delay, effective protection of steel member. Ultra thin intumescent steel structure fire retardant coating can be sprayed, brushed or rolled. It is generally used in building steel structures with a fire resistance requirement of less than 2 h. At present, there has been a fire resistance to meet or exceed the new ultra-thin fireproof coating for steel structure of 2 varieties of H, it is mainly based on the special structure of the poly methyl acrylate or epoxy resin and amino resin, chlorinated paraffin, compound as base adhesive, with high degree of polymerization of ammonium polyphosphate, melamine and pentaerythritol, double as the fire retardant system, adding titanium dioxide, wollastonite and other inorganic refractory material, using 200# as solvent and solvent oil compound. At present, all kinds of light steel structure, grid and so on, use this type of fire retardant coatings for fire protection. Because this type of ultra-thin fireproof paint coating, making use of thick and thin fire retardant coating for steel structure is greatly reduced, thereby reducing the total cost of the project, the steel structure has been effective fire protection, is currently promoting varieties on the market.

Q:Which is better, roofing rock wool or glass wool?

And glass wool is a kind of glass fiber, is a man-made inorganic fiber. Glass wool is the molten glass fibrosis, the formation of cotton like material, chemical composition of glass, is a kind of inorganic fibers. With good forming, small volume density, thermal conductivity, both thermal insulation, sound-absorbing performance, corrosion resistance, chemical stability.
