Ronghua Refractory Technology Co., Ltd. focuses on the research and development and manufacturing of refractory materials and has cooperated with many high-temperature companies around the world for many years.
Mud of fire prevention of good DR-A3-CD02 of inferior quality of price of mud of Changzhou fire prevention is receive a dose to stick with organic synthetic resin, add the classics such as fire prevention agent, filling to Zhan is pressed and be become.
Zhengzhou flourish Cheng Naicai holds to: Quality the first, credit the first, the user is consummate. Scientific administrative constitution, abundant technology force, perfect detect the safeguard that method, advanced tooling, stable product quality is excellent service.
Before the total package mode of fireproof material compares what appear commonly in blast furnace and hot-blast stove of form a complete set to be able to bear or endure on material project, say for EPC mode, more abide are circumfluent in recent years the boiler that change a bed is able to bear or endure to material build by laying bricks or stones is built and be repaired also more and more adoption this kind of mode.
The combinative sex of raw material is to point to clay kind raw material and blame plastic raw material is united in wedlock, form plasticity mud group and have certain dry intensity capacity.
Fire retardant coating is in through brushing paint namely the surface of those combustible material, can increase the fireproof capacity of material, slow down blaze spreads transmission speed, or combustion is prevented in proper time internal energy, this kind of coating calls fire retardant coating, or be called flame retardant coating.
Channel kiln kiln car can be assembled directly after firebrick adobe is taken out from the machine that press a brick, the desiccator before sending toward kiln directly (it and channel kiln are one case repeatedly) , dry hind be not installed via turning and turn pit directly inside firing.
Fireproof degree not a kind of inorganic metalloid material under 1580 ℃ . Fireproof spending is to show body sample is in fireproof material taper to fall without loading circumstance, action of counteractive high temperature and not the centigrade that bate frit pours. But only with fireproof degree will define already cannot depict fireproof material in the round, 1580 ℃ are not absolutely.
be in China, it is fireproof data vendor extremely the area of luxuriant, bring about other abroad to invest business to exported low case to generate doubt to its, be in what offerred new product of fireproof to China material by the European Union 2003 to turn over a dumping thereby, limitted the product export to the European Union.
Guiyang, guizhou Province provincial capital, abbreviation is built, Jin Zhu, have " Lin Cheng " beautiful praise, get a name because of churchyard expensive Shan Zhina, service center of travel of base of the liaison man with center of the politics that is Guizhou Province, economy, culture, science and education, traffic and principal southwest, signal center, industry and trade.
Argillaceous brick is the argillaceous simple product that shows Al203 content is aluminous material of 30% one 40% silicon acid. Argillaceous brick is to use the soft qualitative clay of 50% and grog of 50% horniness clay
So, the porosity that how can just reduce tall aluminous brick appears particularly important. By Zhengzhou flourish next Cheng Naicai introduces how to reduce the porosity of tall aluminous brick for you.
Steel structure is in normally 450 ～ can lose carrying capacity in 650 ℃ temperature, produce very big deformation, bring about steel column, girder to bend, because the result crosses big deformation and cannot continue to use, do not add the fireproof limit of protective steel structure to be 15 minutes or so commonly. This for a short while accident still is concerned with the speed of component part absorption of heat.
