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 exterior wall thermal insulation materials?

Inorganic insulation material:A mineral mineral wool, perlite, vermiculite, diatomite, gypsum, slag, glass fiber, wool, aerated concrete, foam concrete, pumice concrete and its products, chemical synthesis of polyester and synthetic rubber with polystyrene, PVC, polyurethane, polyethylene, urea formaldehyde plastics and foam rigid ester and its products etc..Advantages: this kind of material does not decay, high temperature resistance, partial moisture absorption, easy to burn, more expensive.

Q:Now, what are the new exterior wall thermal insulation materials?

At present do not know the new promotion is that kind, can only suggest you several, because of the advantages and disadvantages, in general, the insulation is not set fire, fire insulation, fire and insulation products prices high ridiculous.

Q:Rock wool, EIA inorganic insulation mortar, polystyrene particles, polystyrene foam board advantages and disadvantages comparison?

EIA: it is a kind of inorganic thermal insulation mortar. It has many similarities with the performance of rock wool. It has good fireproof performance and good durability. It can be synchronized with the structure life. But its handle is better than rock wool, fire class A1, light capacity, low thermal conductivity, high tensile strength, good bonding effect. Can improve the working conditions of workers, harmless to construction personnel, easy construction, directly to the wall, without any binders, direct coating.

Q:What material is fast heated and kept warm?

Heat the heating tube and the aluminum tube with the heat preservation material.There are many kinds of insulation products, including foam plastics, mineral cotton products, foam glass, expanded perlite thermal insulation products, rubber powder, EPS granule insulation paste, mineral spraying cotton and foamed cement insulation products.

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: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:How can the interior drain be silenced?

Sound insulation material: high quality noise proof cotton. Home improvement does not recommend the use of rock wool or other mineral wool because of a little pollution. Although the ordinary sponge does not pollute, but the sound insulation effect is ordinary.Fixed material: tie band, convenient construction, good effect, strong rope can also. Tapes are not recommended for long periods and are easily removed from the sound proof cotton.

Q:What are the properties of fire-resistant coatings for steel structures?

Thick steel structure fire retardant coating refers to the steel structure fireproof coating with coating thickness greater than 7 mm, less than or equal to 50 mm, granular surface, little density, low thermal conductivity, and refractory limit of 2 h or more. Because of the thick fire retardant coating composition for inorganic materials, so the fire performance is stable, long-term effect is good, but the coating components of larger particles, the coating appearance is not smooth, affect the overall appearance of the building, so most structure for concealed works. In the fire, the material has a granular surface, a smaller density, a low thermal conductivity, or a heat absorbing property in the coating, delaying the temperature rise of the steel and protecting the steel. This kind of fire retardant coating is suitable for inorganic binder (such as water glass, silica sol, aluminum phosphate salt, refractory cement, etc.) together with inorganic light insulation aggregate materials (such as perlite, vermiculite, bouldering, sea and fly ash cenosphere), fire retardant additives, chemicals and materials (enhanced such as rock wool, aluminum silicate fiber, ceramic fiber, glass fiber and filler) mixed together, has the advantages of low cost. Spraying is often used in construction. It is suitable for indoor and outdoor concealed steel structure, high-rise steel structure and multi story steel structure with requirements of fire resistance above 2 h. Such as: high-rise building columns, general industrial and civil buildings in support of multi-storey columns of fire resistance should reach 3 h, the need to use this thick fire-retardant coating protection.

Q:Which is better, roofing rock wool or glass wool?

Rock wool: also known as asbestos, is a kind of mineral cotton. A fluffy short staple fiber made from natural rock and minerals. Rock wool is a kind of inorganic fiber made of natural rock, such as Xuan Wuyan, gabbro, dolomite, iron ore, bauxite and so on. It is made by melting and fibrosis at high temperature. Rock wool, used for ablation resistant, high temperature resistant insulating material; sound-absorbing material, insulation building materials and equipment; and natural asbestos substitute for cement products, rubber reinforcing materials and high temperature sealing material, high temperature filter material and high temperature catalyst carrier etc.. 1., insulation performance: good insulation performance, rock wool, slag cotton products basic characteristics. 2., combustion performance 3., sound insulation performance: rock wool, slag cotton products, with excellent sound insulation and sound absorption performance.
