Rock wool is made from natural rock such as basalt, diabase and dolomite. The natural rock are melted into melts in cupola at a very high temperature about 1500°C. And the melts lava is then pour to high speed spinners through which the melts get into fibers. At the same time, the phenolic binder containing silicon and mineral oil etc are sprayed onto the surface of each fiber homogeneously. The just fiberized fibers are collected together to form the original wool mat through negative pressure resulted from suction. The original wool mats then pass through pendulum, crimping and pressing process, get into the curing oven through which the wool mats are cured and shape up to different kinds of products such as board, mat and pipe section etc with different usage.

Rock wool products are free of asbestos, and do not apply any composition harmful to environments such as CFCs, HFCs and HCFCs etc, no harm to human health, do not increase the risk of cancerogenesis. After many years research, the World Health Organization agency of Research made a decision to exempt rock wool from the list of "possibly cancer causing agents". This decision supported the fact that rock wool is safe to users or worker occupational exposure to rock wool fibers.

The properties of non-combustibility, high temperature resistance and porous fiber construction of Jesion rock wool products, makes them have very good performance on fire resistance, thermal insulation and acoustic insulation. The rock wool products are widely use for industry field, building and marine & offshore field to increase the energy efficiency, decrease pollution agent discharge, and improve fire safe situation. Meanwhile, some rock wool products can also be used as the planting substrate for many kinds of vegetables, flowers and fruits.

Q: Rock wool, EIA inorganic insulation mortar, polystyrene particles, polystyrene foam board advantages and disadvantages comparison?: Polystyrene foam board: polystyrene foam board is polystyrene resin as the main raw material, foaming agent made by foaming, with numerous closed microporous material. The utility model has the advantages of small density, small thermal conductivity, low water absorption, good sound insulation performance, high mechanical strength, high dimensional accuracy and uniform structure. But its flammability, combustion, release of toxic gases styrene, B3 grade materials. In the 3.15 exposure of fire accidents, polystyrene foam board accounted for a large proportion, the country has banned the use of.

Q: What is the best sound proof cotton in the decorative plaster board partition wall? Mineral wool rock and glass wool.: Rock wool and glass wool on the overall performance of almost the same, are brittle fiber composition, you need to get a good sound insulation, you need to use high-density materials, usually 80KG per cubic meter of the use of more. The price range is 40-60 yuan per square meter. This material can cause skin allergies and dust can cause respiratory allergies. Therefore, construction should pay attention to the construction personnel physical protection, materials must be completely sealed to the wall inside. If it is a ceiling with holes, you must not use glass wool.

Q: Advantages of exterior wall energy saving and environmental protection heat insulation coating: At present, there are many kinds of exterior wall insulation materials in the market, which can be divided into organic insulation materials and inorganic insulation materials. Materials are inorganic active insulation materials, foam, mineral wool products, foam glass, expanded perlite insulation, powder particles insulation slurry EPS, spraying mineral cotton, foam cement insulation products, vacuum insulation panel etc..

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 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's the difference between glass fiber and mineral wool?: A fluffy short staple fiber made from mineral material. Including rock wool and slag cotton.

Q: What is the difference between high-density rock wool board and hard rock wool board?: But the quality of rock wool is very different, and the heat preservation property is low, the tensile strength is low, and the durability is poor. Glass wool and rock wool in the performance of many similarities, but it feels better than rock wool, can improve the working conditions of workers. But it is higher in price than rock wool.

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: What kinds of fire retardant coatings are there in steel structures?: 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, fire effect is very good.

Q: What are the exterior wall insulation materials?: Extrusion board; this material will be better than the introduction of the benzene board, heat preservation is much stronger, so compared to higher than the price.
