The produce of mineral wool is a kind of Inorganic fiber, the function of which is temperature, heat and sound insulation. It can also be processed into temperature, heat and sound insulation panel.

Applications:

It has been widely used as roof panel and wall panel in steel structure warehouse, factories, exhibition hall, container houses, cold storage, 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 building energy saving materials?: Rock wool is a selection of basalt or diabase as the main raw material, made by melting high temperature inorganic artificial fiber. Rock wool products have good thermal insulation, heat insulation, sound absorption, heat resistance, non combustion, and good chemical stability. Rock wool used for exterior walls of buildings. There are three forms of insulation: internal heat insulation, central sandwich insulation and external insulation.

Q:What's the difference between glass fiber and mineral wool?: Melting natural rock or metallurgical slag in a cupola or a pool furnace, etc. by blowing or centrifuging.

Q:What kinds of exterior wall thermal insulation materials are there in Northwest China?: At the same time it is also the first domestic production of inorganic fiber spraying cotton manufacturers, product quality is stable, a fire, my company production of inorganic fiber spraying equipment durable and convenient transportation has the advantages of small size, light weight, cotton speed, high construction efficiency, speed and other advantages, customer service maintenance. The standard of 6000 yuan / sets, at the same time the product uses a 380 volt -220 volt power supply, which greatly improves its safety and adaptability of the site. To provide a series of service system, our company has ever contracted projects, as the company grew, have business dealings we will build the first China fiber spraying service supermarket across the country, to provide value for all fiber spraying

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.

Q:The classification of exterior wall insulation and its main categories: The second category is the engineering construction industry standards, external wall insulation engineering technical regulations. JGJ144 which includes five kinds of insulation system: the first is the EPS board exterior wall insulation system; second is the powder particles insulation slurry EPS exterior insulation system; third is the cast-in-place concrete wall of EPS board external insulation system; the fourth is a net cast system; fifth is the mechanical fixation of EPS steel wire the grid board exterior insulation system. With the existing external insulation insulation supporting standards, product standards and related engineering construction industry standards. The main supporting product standards are polymer based wall insulation glass fiber mesh; wall energy conservation project construction quality acceptance specification, that is, we know GB50411. Because most of these standards from 2003 to 2007 completed, but because of external wall insulation technology is developing very fast in recent years, the standard of life is short, basically all the standard in the revision, according to the development of technology, there are many standards are approved by the Ministry of construction, is being developed, the revision of the standard is JG149, the JG149 is the revision of the manuscript before the preparatory work. JG158 has just started the startup meeting and is preparing for the update.

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 is the heat preservation material?: According to the different material density, composition, range, shape and construction method of the insulation material, the classification is carried out:According to different bulk density is divided into: heavy 400~600kg/m3, light 150~350kg/m3 and ultra light, less than 150kg/m3 three categories.According to different ingredients: divided into organic and inorganic two categories.

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 is the difference between ordinary slag wool rock wool board and basalt rock wool board?: Although rock wool and cotton products belong to CaO-Al2O3-SiO2 Portland slag system, but because of differences in their chemical composition on (Table 2), making them the phase composition of crystallization point falls in different regions in the CaO-Al2O3-SiO2 three phase diagram (Figure 1). From table 2 and figure 1 shows that the rock composition point (4, 5, 6 in the figure) are located on the 2 wollastonite gehetinite 2 calcium feldspar crystallization zone (CS-C2AS-CAS2 zone), the solid phase will have the three crystalline phase because of wollastonite, gehetinite, calcium do not have hard water feldspar characteristics, the water change is very small, the rock wool has good water resistance.
