Q:what is the raw materials producing glass wool insulation materials?
Glass wool is molten glass that undergoes fibration process, cotton-like material. it is a good shaped inorganic fiber with small volume density, low thermal conductivity, thermal insulation property, sound-absorbing properties, corrosion resistance , chemical stability.
Q:What is the price of glass wool felt ?
Glass wool felt price is about 50 yuan. unit weight: 10 ~ 32 kg / m3 Thickness: 15 ~ 180mm Length: 3m ~ 20m width: 1200mm Note: Special specifications can be customized.
Q:Which one has better noise absorption performance, the mineral wool or the glass wool?
And make it applied to spaces meet the requirements (for example conference rooms require clear voice). Glass wool only absorbs sound over 1500HZ. For example, in order to let the sound field to achieve more pleasant effect, sound-absorbing wool (mineral wool, to remove the noises of people in the waiting room (which is intermediate frequency). Professional sound-absorbing boards can absorb the chosen sound according to which part of sound you need. Curtains are ordinary sound-absorbing matter and absorb only 30%. Performance halls require the sound to reverberate enough but it should not be too long while KTV require the sound appealing.
Q:What is the main use of glass wool insulation materials?
It is generally for home application and cryogenic pipeline with temperature ranging from -120 ℃ -400 ℃, used in construction, petrochemical, power, metallurgy etc. Insulation, sound absorption. Usage: Sound-absorbing walls, sound insulation, wall insulation, wall thermal insulation.
Q:What kind of glass wool pipe is this? Where is it sold?
The glass wool pipe is made of extra-fine glass wool. I do not know this brand. Maybe it is a korean brand.
Q:how to choose external wall insulation materials for glass wool?
Glass wool insulation materials insulate medium and low temperature. it belongs to A level fireproof materials and non-combustible. the use temperature of glass wool insulation material is-120 ℃ -400 ℃, used in construction, petrochemical, power, metallurgy and other fields of thermal insulation, sound absorption. Glass wool glass fibers is a man-made mineral fiber, a kind of glass fiber. Glass wool is molten glass that undergoes fibration process, cotton-like material. it is a good shaped inorganic fiber with small volume density, low thermal conductivity, thermal insulation property, sound-absorbing properties, corrosion resistance , chemical stability.
Q:What's the types of glass wool points? do they have the same sound insulation effect?
Mineral wool and rock wool basically
Q:Polyester and glass wool, which is better, and why?
Polyester fiber is environmental and more suitable for home.
Q:Who knows the construction scheme of external wall thermal insulation glass wool ?
Glass wool external wall insulation construction shceme: in this project, 50 thick glass wool thermal insulation boards are used, which has became popular in Beijing as external wall thermal insulation material only in recent two years so there are no mature check, acceptance and construction specifications. It is constructed according to the design negotiations, the reference standard, Atlas 10BJ2-11, JGJ144-2004, GB50411-2007. Construction of glass wool is difficult. Therefore, construction scheme should be made according to specification and design requirments and negotiation records before construction. At the same time, we should strengthen control during construction and solve problem immediately and construct in strict accordance with Atlas and technical schedule. The insulation construction period of this project is 20 days. It is very tight so we need to make proper arrangement to ensure insulation construction period. Dingfuzhuang Middle School insulation construction: first teachingl buildings, then laboratory buildings, finally canteen. When the outer scaffolds are all constructed in the teaching building, carry out construction in four facades of the teaching building from bottom to up. When the laboratory building outer is sprayed with concrete, carry out laboratory building outer thermal insulation construction. At this time, more workers are needed to ensure insulation constructions of two buildings carried out simultaneously as the teaching building insulation constructio is not finished. When the insulation project is constructed in canteen outer, add more workers to ensure insulation constructions of the three buildings carried out simultaneously.
Q:Could centrifugal glass wool be treated as cold insulation material?
It depends on the specific requirements, now glass wool is not allowed to use in areas with high fire rating and cold insulation requirements.
