Q:What are the exterior wall thermal insulation materials?

Metal insulation material:Mainly aluminum and its products, such as aluminum plate, aluminum foil, aluminum foil, composite light plate, etc.. It uses the radiation characteristics of the material surface to obtain the heat insulation performance.Advantages and disadvantages: with this kind of surface characteristics of the material, almost do not absorb the heat on it, and the ability to radiate heat itself is also very small, this kind of material supply less, more expensive.

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

The inorganic glass magnesium fireproof door core is an inorganic fireproof door core made of Magnesium Oxide and magnesium chloride as cementing material, expanded perlite as filler and foaming. "The building fire prevention design specification" (GB 50016-2006) pointed out, magnesite (magnesium oxychloride) limit refractory pearlstone hollow slat wall material is 1.30h, is not the burning body. According to the test of GB/T9978-2008 on the magnesium oxychloride wall material, the fire resistance of the wall material is completely consistent with the requirements of heat insulation and integrity in 110min, and the fire resistance is 1.83h. Experiments show that the air entraining agent for manufacturing foaming of foamed magnesium cement under the normal temperature and pressure, the density (dry) is 32020kg/m3, the thermal conductivity is 0.076~0.09W/ (M - K), 1.5~2.1MPa compressive strength and softening coefficient is less than 0.6, the surface without powder, shedding dregs phenomenon. Therefore, the inorganic magnesium board with fireproof, heat insulation, excellent mechanical properties, environmental protection, energy saving and economical production cost, filling a fireproof door core material, has the absolute advantage.

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?

Experts from authoritative institutions of Beijing Haina LIAN inorganic fiber spraying technology Co., Ltd. development of ultra-fine inorganic fiber spray identified, it is for the further development of the enterprise is undoubtedly a new impetus. I learned that the evaluation results, both for the enterprise is also happy, for the enterprise how to further enhance their ability of research and development and to further explore this, more hope that the enterprises can take the assessment results in the East, as the struggle to make "Heiner fertility LIAN" on the floor again!

Q:What are the differences between slag wool and rock wool?

People usually referred to as mineral wool rock wool and slag wool, so easy as the two are the same thing, even thought that the slag wool color white, gray green wool is more than "pure", this is a misunderstanding. Although they are all mineral cotton, there are still some differences that can not be ignored. The main reason for these differences is the composition of the ingredients.

Q:What are the requirements for floor and exterior wall waterproofing in building construction?

Building exterior wall waterproof design should include the structure through windows and doors, awning, balcony, cracks, out wall casing, capping, embedded parts, prefabricated wall parapet and the intersection area of waterproofing. 5.1.3 the waterproof layer of the exterior wall shall be installed on the surface of the water.

Q:How about the appearance of glass wool, mineral wool and asbestos?

Glass wool belongs to a kind of glass fiber, it is a kind of man-made inorganic fiber. Quartz, sand, limestone, dolomite and other natural ore as the main raw materials, with a number of soda ash, borax and other chemical raw materials into glass. In the melting state, by means of external force, the system is thrown into flocculent fibers, and the fibers and fibers are made of solid intersection. They are intertwined with each other and show a lot of small gaps. This gap can be considered as a pore. Therefore, the glass wool can be regarded as a porous material and has good thermal insulation and sound absorption performance.

Q:The difference between rock wool and mineral wool

Cotton like short staple fibers made from silicate melts, including slag cotton, rock wool, glass wool and ceramic fibers, generally only refer to the first two.

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!

Q:Exterior wall insulation putty powder construction needs to pay attention to what problems?

The production enterprise of rock wool board insulation system should have professional guidance in the construction process, and cooperate with construction units and site supervision to do construction quality control work. Material access must be in accordance with specifications, quantity and quality requirements, after acceptance of qualified to storage, and should be kept by hand, is strictly prohibited open-air stacking. Curtain wall rock wool board should be overhead damp proof piling up. Plastering construction should meet the following requirements: rock wool board paste after surface treatment with plaster surface plate, scraping the mortar on the surface coated with a stainless steel spatula (thickness 1 ~ 1.5mm), and press the rock wool board surface fiber. Mortar should be configured in strict accordance with product instructions, configuration of the adhesive should avoid direct sunlight, and should be used within 2h.
