Q:What is the common inorganic fireproof and thermal inuslation matertial?
Ceramic foam insulation board is made from clay tailings, ceramic broken flake and river silt, which is the closed ceramics material with high porosity roasted in high temperature by advanced production technology and foam technology. Products have fire retardant, small deformation coefficient, aging resistance, stable performance, good environmental protection, good compatibility between wall base and plastering layer, good safety and soundness and a lifetime as long as the building itself.
Q:What is streaming fireproof material?
Since streaming fireproof material has less surface energy, so when it is placed in a location to be used, it can be automatically filled so long as mixed with water at proper ratio. And then using vibrator or vibrostand and other tools to compact the mixture so as to satisfy the use requirements. Therefore, it does not require vibration, and it has less friction force between the particles. Generally hydraulic refractory castable must be mixed with water at proper ratio when in construction . While, the concept of "streaming" is in terms of refractory castable.
Q:Who knows about the types of Dalian thermal insulating and refractory materials?
There are many Dalian thermal insulation materials, which can be divided into organic and inorganic thermal insulation materials. Materials include inorganic thermal insulation materials, polyfoam, mineral wool products, foam glass, expanded perlite insulation products, gelatine powder EPS grain heat insulating slurry, sprayed mineral wool, thermal insulation product of foam cements, and vacuum thermal insulation board.
Q:What are the characteristics of phenolic resin as a refractory material?
Q:Which one is the best refractory material?
o make it simple, you can kindle it, and observe the burning time. If there is a professional need to be accurate, then you can send it to the professional testing company. As far as I know, the Kebiao Company over the victory bridge, Qingdao can offer professional test. I hope my answer can help you, thank you, hope to be adopted.
Q:How to classify the grade of wall fireproof and thermal inuslation matertial?
External wall thermal insulation materials are mainly divided into grade A, grade B1, grade B2 and grade B3. In accordance with the current "Combustion Performance Classification Method of Building Materials", grade A thermal insulation material is incombustible material and belongs to inorganic heat preservation material. However, grade A thermal insulation material is few in terms of the current market. There are only JETCO YT inorganic active wall thermal insulation material, glass wool, rock wool board, foam glass, vitrified micro bead and grade A fireproofing thermal insulation board. However, compared with grade A thermal insulation material, the more welcomed by the market is the organic insulation materials. Thermal insulation material that is determined as grade B is divided into three levels. Grade B1 is grade is flame retardant. Grade B2 is combustible. Grade B3 is flammable.
Q:Could you tell me the fire-resisting time of class B fire proof door?
Could you tell me the fire-resisting time of class B fire proof door?
Q:What are the raw materials of refractory? And what are their names?
Q:how to classify Insulating Refractory ?
General materials have test reports, where fire rating is labled.
Q:What is the the best matching ratio of refractory cement?
Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will produce a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees. Refractory cement can be used together with ordinary sand, and the ratio of cement and the sand is about 30 percent.
