Q:What is the heating tube cotton insulation material itch on the body?

Commonly used raw materials are iron, phosphorus, nickel, lead, chromium, copper, manganese, zinc, titanium and other slag. Mainly used as insulation material and sound-absorbing material. Iron packing materials can also be used. Slag cotton is made of industrial waste, slag (blast furnace slag or copper slag, aluminum slag, etc.) as the main raw material, by melting, using high-speed centrifugation or injection process, such as cotton filamentous inorganic fiber. It has the characteristics of light weight, small thermal conductivity, no burning, mothproof, cheap, corrosion resistance, good chemical stability, good absorption performance. It can be used for building insulation, sound absorption, sound insulation, oxygen generator and cold storage, cold insulation and insulation of various thermal equipments.

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 is the best sound proof cotton in the decorative plaster board partition wall? Mineral wool rock and glass wool.

At present, the market is the best sound effect is said to be gradient sound-absorbing cotton, as well as high barrier sound felt. The price is relatively high, the price range is 55-80 yuan per square meter. The advantages of its products are more environmentally friendly, first of all, the construction will not cause skin itching. No emissions. It won't be pulverized. The sound absorption effect is reflected in the full frequency silencing, and has a good reduction effect on low frequency, intermediate frequency and high frequency sound. High barrier acoustic felt is reflected in its high damping performance. It can effectively restrain the sound propagation caused by resonance when it is attached to the thin plate. Usually relatively high-end, or official sites are more respected.

Q:Does water paint spray fire in underground space?

NeededWater based brand fire retardant paint thickness is determined by base material, such as wood, steel structure, etc.:1. ultra thin structure fire retardant coating (0-3mm)2. thin steel structure fire retardant coating (3-7mm), fire-resistant 2-5h3. thick steel structure fire retardant coating (7-45mm), applicable to high-rise civil buildings, columns, general industrial and civil construction, fire up to more than 3H4. mineral cotton fire retardant insulation coating

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

The EPS plate shall be bonded in a vertical arrangement and the vertical seam shall be staggered along the line. Insulation board construction fault seam stitching truth with brick walls are brick seam is a reason for strong security.

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:How can the interior drain be silenced?

A sewer pipe commonly used rock wool make noise processing (must be closed, it is said that rock wool can be carcinogenic) but in general, even a simple sound will hear the noise, just reduce it, if there is higher demand for insulation,You can also use wooden boards to make boxes, wrap the hose down, fill it with foam, and, with the aid of the ceiling material, reduce noise. Such as: sound-absorbing board, PVC foam board and so on.

Q:What are the differences and prices between rock wool board and mineral wool board?

Its main chemical components are silica, three, two aluminum oxide, calcium oxide, Magnesium Oxide, and a small amount of iron oxide, etc., and a small amount of phenolic resin is added to make the molding;

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..
