Rockwool products have many practical uses; the following are some of the main fields:

In the Thermo-acoustical field Rockwool is used for the insulation of buildings of all types and uses, such as houses, department stores, offices, athletic buildings, airports, etc.

In insulating industrial plants buildings and mechanical systems like:

Cooled stores.

Refineries.

Chemical and Petrochemical Plants.

Central Air conditioning.

Hot water and chilled water systems.

For industrial purposes, Rockwool is used in many industries

Q: What is the best sound proof cotton in the decorative plaster board partition wall? Mineral wool rock and glass wool.: At present, the market is the best sound effect is said to be gradient sound-absorbing cotton, as well as high barrier sound felt. The price is relatively high, the price range is 55-80 yuan per square meter. The advantages of its products are more environmentally friendly, first of all, the construction will not cause skin itching. No emissions. It won't be pulverized. The sound absorption effect is reflected in the full frequency silencing, and has a good reduction effect on low frequency, intermediate frequency and high frequency sound. High barrier acoustic felt is reflected in its high damping performance. It can effectively restrain the sound propagation caused by resonance when it is attached to the thin plate. Usually relatively high-end, or official sites are more respected.

Q: What are the exterior wall thermal insulation materials?: Organic thermal insulation material:Such as rice straw, rice husk, sugarcane fiber, softwood, kapok, sawdust, wood shavings, wood fiber and their products.Advantages: this kind of material has a small volume, a wide range of sources, most of the low price, but the moisture absorption is large, easy to decay after damp, and easy to decompose or burn at high temperature.

Q: What are the kinds of fire door core board?: The inorganic glass magnesium fireproof door core is an inorganic fireproof door core made of Magnesium Oxide and magnesium chloride as cementing material, expanded perlite as filler and foaming. "The building fire prevention design specification" (GB 50016-2006) pointed out, magnesite (magnesium oxychloride) limit refractory pearlstone hollow slat wall material is 1.30h, is not the burning body. According to the test of GB/T9978-2008 on the magnesium oxychloride wall material, the fire resistance of the wall material is completely consistent with the requirements of heat insulation and integrity in 110min, and the fire resistance is 1.83h. Experiments show that the air entraining agent for manufacturing foaming of foamed magnesium cement under the normal temperature and pressure, the density (dry) is 32020kg/m3, the thermal conductivity is 0.076~0.09W/ (M - K), 1.5~2.1MPa compressive strength and softening coefficient is less than 0.6, the surface without powder, shedding dregs phenomenon. Therefore, the inorganic magnesium board with fireproof, heat insulation, excellent mechanical properties, environmental protection, energy saving and economical production cost, filling a fireproof door core material, has the absolute advantage.

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: The water heater for what the security hole tube: Gas water heater, smoke exhaust pipe, mineral wool, rock wool, glass fiber, etc..

Q: Why should the insulation board be spliced when it is installed?: Thermal insulation materials are generally used to guide heat coefficient less than or equal to 0.2 of the material. Thermal insulation material development is very fast, and in industry and building the use of good insulation technology and materials, often can get twice the result with half the effort. Each ton of mineral cotton insulation used in the building saves one ton of oil a year.

Q: What are the differences and prices between rock wool board and mineral wool board?: Its main chemical components are silica, three, two aluminum oxide, calcium oxide, Magnesium Oxide, and a small amount of iron oxide, etc., and a small amount of phenolic resin is added to make the molding;

Q: What is the difference between ordinary slag wool rock wool board and basalt rock wool board?: Rock wool and slag cotton belong to mineral cotton, and they have many similarities in the production process, fiber morphology, alkali resistance, thermal conductivity and non combustibility. People usually referred to as mineral wool rock wool and slag wool, so easy as the two are the same thing, even thought that the slag wool color white, gray green wool is more than "pure", this is a misunderstanding. Although they are all mineral cotton, there are still some differences that can not be ignored. The main reason for these differences is the composition of the ingredients.

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 the heating tube cotton insulation material itch on the body?: Commonly used raw materials are iron, phosphorus, nickel, lead, chromium, copper, manganese, zinc, titanium and other slag. Mainly used as insulation material and sound-absorbing material. Iron packing materials can also be used. Slag cotton is made of industrial waste, slag (blast furnace slag or copper slag, aluminum slag, etc.) as the main raw material, by melting, using high-speed centrifugation or injection process, such as cotton filamentous inorganic fiber. It has the characteristics of light weight, small thermal conductivity, no burning, mothproof, cheap, corrosion resistance, good chemical stability, good absorption performance. It can be used for building insulation, sound absorption, sound insulation, oxygen generator and cold storage, cold insulation and insulation of various thermal equipments.
