Q:How about the quoted price of asphalt glass wool felt?
The sound absorption property of glass wool board is related to veneer materials, cavity and cavity's size, the thickness of glass wool board and apparent density. Test shows that sound absorption property of glass wool board is mostly related to the thickness of board.
Q:What is the main use of glass wool insulation materials?
Uses of glass wool insulation material, glass wool: The main raw materials are glass, class A fireproof rating, thermal conductivity coefficient 0.037, shrinking temperature of 270 degrees, use: Good cold insualtion property.
Q:What's the difference between glass wool board and rock wool board ?
Glass wool is glass wool roll mat made through fibering of molten glass and then solidification by adding binder, and fibre diameter of glass wool depends on centrifugation extrusion technology. The difference is the centrifugation techniques, TEL centrifugation technique of Saint-gobain Aesop who is the founder of glass wool, is the most popular technique currently. At present the domestic glass wool market is gradually expanding. Companies such as Quanhe Chemical Co., Ltd. in Dacheng have made significant contributions to promote glass wool. Rock wool board is artificial inorganic fibers made from basalt, and processed through melting in high temperature, with light weight, low heat conductivity coefficient , heat absorption, non-combustible characteristics. The initial development should be consistent with stipulation in Application types and basic requirements of building thermal insulation materials. It is generally used in industrial architectures. Pilot run succeeded in June 198. Rock wool board is new type of thermal insulating, fire retardant and sound absorbing material.
Q:Where are the differences between the glass wool board and glass wool blanket?
Glass wool felt is generally used to the top of industrial plants, which is roll-like; glass wool board is mainly used for external wall heat insulation, which is board-shaped.
Q:Who know the construction technology of glass wool?
1, The construction condition. 1.1, The substrate must be dry and be passed acceptance inspection. 1.2, The construction site should be granted with no more than five grade of wind force during construction. 1.3, Effective measures should be taken during construction in rainy days to prevent glass wool from being wetted by rainwater. 2, the main construction tools: wllpaper knife, electric screwdriver and fe, electric screwdriver, 2m guiding rule. 3, Construction process. 4. Construction points. 4.1, Construction preparation: 4.1.1, Material preparation: Prepare the detailed supply planned order of materials according to the drawings and projects condition. All materials approved into the site must be qualified products, complying with the relevant regulatory requirements nationally, industrially and locally. 4.1.2 Construction machinery: All machinery must be tested to ensure their good performance. 4.1.3, Personnel preparation: Technical personnel must be provided with technical training and technical disclosure.
Q:Can Kunnai glass wool board and sound absorption blankets be used to maintain sound insulation in hotel floor? Can it decrease half of the noise? How to install?
Pour concrete with the thickness of 4-6 cm to the shock absorption pad. The floor treatment is mainly for solid conduction, and the surroundings also need to be isolated by shock pad. Shock absorption pad and concrete floor can ensure that the newly-poured floor is not hard-wired with the original building.
Q:Which one among polystyrene boards, rock wool boards and glass wool boards is the best materials for external wall thermal insulation?
According to the "Provisional Regulation of Civil Building External Thermal Insulation System and Exterior Wall Decoration Fire Prevention" issued by Ministry of Public Security and Ministry of Housing and Urban-Rural Development, the fireproofing performance of it should not be lower than B2-level. Rock wool board and glass wool are both accessible if taking cost into consideration. The combustion performances of polystyrene boards are generally C- and B1-level, while the combustion performance of external wall thermal insulation materials should be A-level.
Q:Does glass wool belong to the asbestos insulation material?
Asbestos products have many varieties and they are mainly used for thermal insulation in industrial equipment and industrial pipes. The operating temperature is within 600 ℃. Compared with glass wool, asbestos products also have more forms. They include asbestos cloth, rope, tape, sheet, blanket, packing (sealing materials), quilt (for fire suppression) and paper.Glass wool is mainly used for thermal insulation of buildings and air ducts. The operating temperature is within 450 ℃.The main products areglass wool plates and carpets.It need to be noted that asbestos is non-environmentally friendly materials and it is radioactive. Long-term contact with it may do great harm to the human body, thus the production of it is banned.
Q:How about the sound insulation performance of glass wool felts?
Fix the glass wool in the wall with pegs, then cover it with plywood, after laying up with wooden surface, nail the wood again.
Q:What's the difference between the rock wool and glass wool?
Rock wool takes natural basalt as the main raw material, after high temperature melting, artificial inorganic fibers are made by high speed centrifugal equipment, at the same time, add special binder and dustproof oil, then through heat curing, made into a variety of specifications rock wool insulation products with different requirements. Rock wool products are widely used for construction, petroleum, electric power, metallurgy, textile, national defense, transportation and other industries, is the ideal material for thermal insulation and sound insulation of pipeline storage tank, boiler, flue, heat exchangers, fan, transport and other industrial equipment. Rock wool board can resist high temperature of 650 degrees. Glass wool belongs to a category of glass fiber, and is a kind of man-made inorganic fiber. Glass wool is a kind of spongiform material shaped by making melten glass fibering, it's chemical content belongs to glass and is a kind of inorganic fiber. It has good molding, small bulk density, low thermal conductivity, good thermal insulation and heat insulation, good sound absorption, corrosion resistance and stable chemical performance. the internal side of centrifugal glass wool exists crisscross fibers and many tiny air voids, is typical porous sound-absorbing material, has good sound absorption characteristics. Glass wool can resist high temperature of 450 degrees.
