Q:The water heater for what the security hole tube

Gas water heater, smoke exhaust pipe, mineral wool, rock wool, glass fiber, etc..

Q:What are the kinds of fire door core board?

Inorganic fireproof insulating material, fire door core, such as rock wool, mineral wool, glass wool, aluminum silicate cotton, asbestos, expanded perlite, expanded vermiculite products, foam glass, microporous calcium silicate products. Inorganic materials are far better than organic materials and fire insulation performance and smokeless toxic performance, but there are some limitations, some non compressive degrees, must be attached to support carrier, carrier and brought fire and burning smoke toxicity problems, such as rock wool, mineral wool, glass wool, cotton, aluminium silicate asbestos is such; some high prices, the production of high energy consumption, such as foam glass, microporous calcium silicate in the case of such refractory; some itself is not high, moisture absorbent is large, such as cement or water glass based products, perlite cement or water glass based products, products such as vermiculite foam concrete is such, therefore restricted to varying degrees as the filling core material of the fire door.

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: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: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:Why should the insulation board be spliced when it is installed?

Thermal insulation materials are generally used to guide heat coefficient less than or equal to 0.2 of the material. Thermal insulation material development is very fast, and in industry and building the use of good insulation technology and materials, often can get twice the result with half the effort. Each ton of mineral cotton insulation used in the building saves one ton of oil a year.

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 materials should be used for building energy saving? Why?

Energy saving materials are widely used in building energy saving materials development and promotion in China. They have significant social, economic and environmental benefits, with great potential. 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: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:Fire retardant plywood does not belong to non-metallic refractory building 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..
