What are the exterior wall insulation materials?
- Benzene plate. The price of this material is relatively cheap, because its heat preservation effect is not ideal. And after the rain will be deformed, very easy to absorb water; therefore, the use of this material usually waterproof.s
What are the properties of fire-resistant coatings for steel structures?
- Thin coating steel structure fire retardant coating refers to the coating thickness of more than 3mm, less than or equal to 7 mm, with certain decorative effect, high temperature expansion and thickening, fire resistance within 2 H steel structure fire retardant coating. The fire retardant coating for steel structure is made up of suitable water polymer as base material, compounded with flame retardant compound system, fireproof additive, refractory fiber, etc. the principle of fire protection is super thin. For this kind of fire retardant coating, the water borne polymer must have good adhesion, durability and water resistance. Its decorative properties are better than those of thick fireproof coatings, which are inferior to those of super thin steel structure fire retardant coatings. The average fire resistance is within 2 h. Therefore, spraying construction is often used in steel structure fire protection engineering which is less than 2 h fire resistance limit. This kind of products occupy a large proportion in a period, but with the emergence of ultra-thin steel structure fire retardant coating, its market share is gradually replaced.s
Which is better, roofing rock wool or glass wool?
- And glass wool is a kind of glass fiber, is a man-made inorganic fiber. Glass wool is the molten glass fibrosis, the formation of cotton like material, chemical composition of glass, is a kind of inorganic fibers. With good forming, small volume density, thermal conductivity, both thermal insulation, sound-absorbing performance, corrosion resistance, chemical stability.s
What is mineral fiber cotton? Yes, it's insulation.
- Mineral fiber cotton is a kind of cotton fiber which is made from various mineral raw materials by melting and fiber forming and by surface treatment with different organic and inorganic reagents.s
Fireproof rock wool board can be used as firewall?
- Composite rock wool board and slag wool board referred to as mineral wool, slag wool has been widely used in metallurgy, machinery, building materials, petroleum and chemical industry in 1970s, rock wool used for external wall thermal insulation in developed countries such as the EU has a history of nearly 30 years, but in our country because of its high cost and production cost, the economic costs of organic insulation the material is greater than, the application range is not big.s
What materials should be used for building energy saving? Why?
- Glass wool is second kinds of products of mineral wool, with silica sand, limestone, fluorite and other minerals as the main raw material, by melting method and centrifugal method, using flame or high energy gas blowing process, the molten glass liquid made of inorganic fiber. Glass wool products have good thermal insulation, heat insulation, sound absorption, non burning, corrosion resistance and other properties. They are widely used in building, piping, storage tanks, boilers, aircraft, ships and other parts of the insulation, heat insulation and sound absorption.s
External wall insulation rock wool board construction points and matters needing attention, know how much?
- 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.s
