Q:What is the difference between high-density rock wool board and hard rock wool board?

But the quality of rock wool is very different, and the heat preservation property is low, the tensile strength is low, and the durability is poor. Glass wool and rock wool in the performance of many similarities, but it feels better than rock wool, can improve the working conditions of workers. But it is higher in price than rock wool.

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

Red apple exterior wall paint, thermal insulation coating, the price is very high

Q:What are the exterior wall insulation materials?

Extrusion board; this material will be better than the introduction of the benzene board, heat preservation is much stronger, so compared to higher than the price.

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

Rock wool and slag cotton belong to mineral cotton, and they have many similarities in the production process, fiber morphology, alkali resistance, thermal conductivity and non combustibility.

Q:The classification of exterior wall insulation and its main categories

The first is the product standard, the complete expansion of polystyrene board external insulation board system, this system in our country now use probably accounted for more than 62%, some statistics in 80%, because the statistics are not accurate, but it is the highest market share, is also the most mature external insulation system.

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 about the appearance of glass wool, mineral wool and asbestos?

A fluffy short staple fiber made from mineral material. Including rock wool and slag cotton. Melting natural rock or metallurgical slag in a cupola or a pool furnace, etc. by blowing or centrifuging.

Q:What is the difference between ordinary slag wool rock wool board and basalt rock wool board?

Rock wool and slag cotton belong to mineral cotton, and they have many similarities in the production process, fiber morphology, alkali resistance, thermal conductivity and non combustibility. 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 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: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.
