Q: How can refractory materials be divided?: Refractory materials in China can be roughly divided into refractory products and unshaped refractories.

Q: What's the fireproof specification for constrcution external wall thermal insulation materials?: Specification for constrcution external wall thermal insulation materials: Article 1 In order to implement the "State Council opinions on strengthening and improving fire prevention work" (state issued [2011] No. 46), to standardize fireproof design and application of external wall thermal insulation materials of newly constructed, renovated, and expanded civil buildings and to prevent and reduce fire of building external wall thermal insulation materials, this provision is made in accordance with relevant national technical standards and our province real situation. Article 2 When there is no cavity between external wall thermal insulation material for exterior wall and base wall and between decorative layers, the insulation system shall comply with the following provisions: (A) Residential buildings: 1. When the building is higher than 54m, combustion performance of the thermal insulation material shall be A level; 2. When the building is not higher than 54m,combustion performance of the thermal insulation material shall be at least B level. When using B1 level insulation materials, non-combustible materials should be used to make the protective layer, and a protective layer thickness of the first floor of the building should be not less than 10mm, the other floors not less than 5mm; incombustible?materials of more than 300mm height should be used to make horizontal fire barrier zone in every floor. (B) Other buildings in addition to residential buildings

Q: Application of refractory materials in petroleum industry: Our natural gas transportation, chemicals, equipment, packing, safety, insulation, and even building materials are available.

Q: How to hang the suspended brick in the refractory masonry?: First you can weld the metal fastener of the suspended brick and then hang up the brick.

Q: Does anyone know about the fire resistance period of thin fireproof coatings?: The thin fireproof coatings will be expanded when exposing to open fire, and produce the inert gas to extinguish fire, but they will do harm to people, and the coatings are not stable, and the weather resistance and service life of which are short. According to the state regulations, the thin fireproof coatings have the highest fire resistance of only 2.5 hours, while the thick steelwork fireproof coatings have a fire resistance of 3.0 hours or more.

Q: I wanna ask what are the acidic refractories?: (1) silica?brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity.

Q: Can refractory be used as sealing element?: It can. For example, fiber ceramics can resist high temperature! !

Q: The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.: What thermal equipment? The most simple principle is durable, low cost and with no environmental pollution.

Q: What are the differences between thermal?insulation?material and refractory?: Just as its name implies, Thermal insulation means that it doesn't conduct heat instead it insulates heat inside, while refractory means resistance to high temperature and it will not be out of shape or damaged due to high temperature.

Q: Does anyone knows which company produces the better refractory materials?: I recommend Xinjiang Yuanyangrefractory material Co., Ltd. Address: Near Xishan Road No.100, Saybagh District,Urumqi. Their products are both in good quality and reasonable price. In addition, there are Xinjiang Zhongwang refractory material factory, Address: Xi hongxi Road No. 769, Urumchi City. They all have a good reputation. You may think about it. 。
