Rock wool is a mineral inorganic fibrous material with excellent and distinguished properties and characteristics. It is efficiently applied in all fields of thermo-acoustic insulation; furthermore it is used in many industries and agricultural activities. It is water proof rock wool.

Q: External wall insulation rock wool board construction points and matters needing attention, know how much?: Rock wool, that is, a kind of exterior insulation material. When the market holds 90% of the organic thermal insulation material at a standstill, as the fire protection level of the exterior wall insulation, inorganic materials, rock wool has ushered in an unprecedented market opportunity. Therefore, when using rock wool board, there are some we need to understand. Rock wool board insulation system for energy-saving insulation project construction should be in accordance with the review of qualified construction drawing design documents and approved by the project for energy-saving insulation project construction plan.

Q: What are the properties of fire-resistant coatings for steel structures?: Thick steel structure fire retardant coating refers to the steel structure fireproof coating with coating thickness greater than 7 mm, less than or equal to 50 mm, granular surface, little density, low thermal conductivity, and refractory limit of 2 h or more. Because of the thick fire retardant coating composition for inorganic materials, so the fire performance is stable, long-term effect is good, but the coating components of larger particles, the coating appearance is not smooth, affect the overall appearance of the building, so most structure for concealed works. In the fire, the material has a granular surface, a smaller density, a low thermal conductivity, or a heat absorbing property in the coating, delaying the temperature rise of the steel and protecting the steel. This kind of fire retardant coating is suitable for inorganic binder (such as water glass, silica sol, aluminum phosphate salt, refractory cement, etc.) together with inorganic light insulation aggregate materials (such as perlite, vermiculite, bouldering, sea and fly ash cenosphere), fire retardant additives, chemicals and materials (enhanced such as rock wool, aluminum silicate fiber, ceramic fiber, glass fiber and filler) mixed together, has the advantages of low cost. Spraying is often used in construction. It is suitable for indoor and outdoor concealed steel structure, high-rise steel structure and multi story steel structure with requirements of fire resistance above 2 h. Such as: high-rise building columns, general industrial and civil buildings in support of multi-storey columns of fire resistance should reach 3 h, the need to use this thick fire-retardant coating protection.

Q: What kinds of exterior wall thermal insulation materials are there in Northwest China?: There are a lot of external insulation materials, including foam, mineral wool products, foam glass, expanded perlite insulation, powder particles insulation slurry EPS, spraying mineral cotton, foam cement insulation products, polystyrene particles, internal and external wall thermal insulation glazed hollow bead mortar and external wall putty and so on, you can according to the preferences and choose one or several price.

Q: What is the heat preservation material?: In accordance with applicable temperature range: can be divided into high temperature (700 degrees Celsius), medium temperature (1000~700 degrees Celsius) and low temperature (less than 100 degrees Celsius) three categories..According to different shapes are divided into: powder, granular, fibrous, block and other categories, but also divided into porous, mineral fiber and metal.According to different construction methods are divided into: wet wipe, filling type, lashing type, wrapped winding type, etc..

Q: 8cm what is the sound volume of the soundproof cotton?: Restate the professional point of view, the sound-absorbing material as insulation, sound-absorbing insulation materials or when used is not scientific. In both sound and sound (such as the design of reverberation time) when the need to use composite insulation board and sound-absorbing materials, can not only ensure the system sound transmission coefficient is small, and ensure the sound reflection weakened reach, sound insulation and sound absorption cream effect.

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 are the common thermal insulation materials?: 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: Exterior wall insulation putty powder construction needs to pay attention to what problems?: When the market holds 90% of the organic thermal insulation material at a standstill, as the fire protection level of the exterior wall insulation, inorganic materials, rock wool has ushered in an unprecedented market opportunity. Therefore, when using rock wool board, there are some we need to understand. Rock wool board insulation system for energy-saving insulation project construction should be in accordance with the review of qualified construction drawing design documents and approved by the project for energy-saving insulation project construction plan.

Q: What kinds of fire retardant coatings are there in steel structures?: The utility model can be expanded and expanded slowly when the fire is in place to form a dense and hard fireproof heat-insulating layer, and the fireproof layer has strong fireproof impact property, and the temperature rise of the steel is delayed, and the steel member is effectively protected. 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. There have been 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, double itrate alcohol, melamine as four fire retardant system, adding titanium dioxide, wollastonite and other inorganic refractory material, using 200# as solvent and solvent oil compound. All kinds of light steel structure, grid and so on, use this type of fire retardant coatings for fire protection.

Q: Fireproof rock wool board can be used as firewall?: You need to know what material the firewall is made of What are its standards and requirements? What's the function of it? When you know all about it, you won't take a piece of board to make a wall!
