Rock wool board is made of select fine basalt as the major materials which is pulled into 4-7µ non-continuous fibers after melted by adopting advanced international four-roller centrifugal cotton-making procedures and adding a certain of adhesives, dust laying oil and water repellent into rock wool fibers. It can be made into products series with different density according to various uses through the technology of sedimentation, solidify, cutting and etc.
- Q: Rock wool, EIA inorganic insulation mortar, polystyrene particles, polystyrene foam board advantages and disadvantages comparison?
- EIA: it is a kind of inorganic thermal insulation mortar. It has many similarities with the performance of rock wool. It has good fireproof performance and good durability. It can be synchronized with the structure life. But its handle is better than rock wool, fire class A1, light capacity, low thermal conductivity, high tensile strength, good bonding effect. Can improve the working conditions of workers, harmless to construction personnel, easy construction, directly to the wall, without any binders, direct coating.
- Q: What are the building energy saving materials?
- At present, China's common energy-saving insulation materials are mainly rock wool, glass wool, polystyrene foam, cement, polystyrene board, silicate composite insulation mortar.
- 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: 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 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?
- You said if you want to use 8cm cotton insulation wall system to suppress the noise effect, must be added on both sides of the insulation cotton high density (or surface density) of the building materials, such as gypsum board, glass magnesium board, calcium silicate board, fiber cement board and so on. If we want to ensure that the partition wall should not be too thick, and to ensure the sound transmission loss of more than 50dB, it is not up to use the common plate, must use the Chong Ning insulation board and other professional sound insulation board, can achieve the wall thickness in the case of 100~130mm Rw, the weighted sound insulation amount reached more than 50~54dB, and the highest standards of sound insulation value reached the national standard of civil building insulation standards.
- Q: What are the building thermal insulation materials in general?
- Building thermal insulation material is to take measures to reduce the heat inside the building to the outside, so as to maintain the indoor temperature of building. Building insulation material plays an important role in creating suitable indoor thermal environment and saving energy in building insulation.
- Q: Fire retardant plywood does not belong to non-metallic refractory building materials
- 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.
- 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: What are the differences and prices between rock wool board and mineral wool board?
- Rock wool and mineral wool belong to mineral wool, are made of natural rock, or (and) slag as raw materials, high temperature melting, formed in the interaction of centrifugal force and air under inorganic fibrous products;
