Address: No. 1, seven weft Road, Binhai Road, Yingkou, Liaoning.
Light weight, generally 10-96 kg/m3, 20 kg/m3 below for felt, 24-48 kg/m3 for medium-hard board, 48-96 kg/m3 for hard board, of which 48 kg/m3 can be used as the ceiling, softening point is about 500 degrees C, insulation 300 degrees C, the United States larger amount, k = 0.9.
Calcium silicate insulating products have been developed successfully in the 1970s. They are characterized by high compressive strength, low thermal conductivity, convenient construction and reusable. They are widely used in power system. Most of China is generally small workshop type production, and then from the United States to import four production lines, advanced technology, fast-dissolving fiber, dry needle-punched felt, stable quality, can withstand 800-1250 degrees C.
Characteristics: acidity derivative more than 2, high temperature resistance, general chemical pipeline 1000 degrees C more, we must use this material. The temperature is about 2000 degrees C. Foam plastics is based on synthetic resin, with innumerable holes in the interior of plastic products, it has low thermal conductivity, processing molding and other advantages, in the building has just begun to use. It is mainly used for packaging industry (such as refrigerator), underground directly buried pipeline insulation, cold storage and cold storage.
The main products are building materials factory, green building materials polystyrene foam plastics and polyurethane foam plastics, but there are problems in the application of construction field. Although there are some limitations in the application of sandwich panels made of steel wire mesh and color steel plates, the development of sandwich panels is fast. With the increasingly stringent requirements for materials in building fire protection, new problems are put forward in the application of this material.
