Q: What are the electrical fire protection materials?: Inorganic binder: Water glass, gypsum, phosphate, cement, etc.; Refractory mineral filler: Alumina powder, calcium carbonate, asbestos, perlite, cornstarch; the main purpose of electrical fire prevention board is to prevent fire and heat. The heat conductive plate will conduct electricity, leading to good equipment insulation and large superheating surface! ! ! ! Hope my answer will help you.

Q: Can quantitative feeder be used in refractory plant? Thank you: Feeder experts, justice and analysis, quantitative feeder, of course, can be used in refractory plants

Q: Which brand of thermal insulating refractory is good?: Brands of thermal insulating refractory: 1, Armaflex(German brand). Manufacturer: Armacell thermal insulation materials (Guangzhou) Co., Ltd, Armacell thermal insulation materials (Suzhou) Co., Ltd. 2, Durkflex (American brand) Manufacturer: Durkee (Guangzhou) thermal?insulation?material Co., Ltd. Durkee (Wuhan) thermal?insulation?material Co., Ltd. 3, Aeroflex (Thailand Brand) Manufacturer: Aeroflex Polymer Technology (Shanghai) Co., Ltd.

Q: I want to consult the fire resistant level standards of external wall thermal insulation materials.: 1, The building with the height larger than or equal to 100m, should have the A-level combustion performance. 2, The thermal insulation material of the building, with a height larger than or equal 60m and less than 100m, should not be less than the level B2 combustion performance. When using the level B2 insulation material, each level should set horizonal fire barrier zone. 3, The thermal insulation material of the building, with a height larger than or equal to 24m and less than 100m, should not be less than the level B2 combustion performance. When using the level B2 insulation material, each two levels should set horizonal fire barrier zone. 4, The thermal insulation material of the building, with a height less than 24m, should not be less than the level B2 combustion performance. When using the level B2 insulation material, each three levels should set horizonal fire barrier zone. I hope my answer will help you. Thank you!

Q: How to classify the grade of wall fireproof and thermal inuslation matertial?: To sum up three versions of GB8624 (1997, 2006, 2011), fire?rating of external wall thermal insulation can be basically divided into: A1, A2, B1, B2, B3 and other levels. Specific division has many technical indicators to judge. It can't be said for a moment. It is very professional and technical. For details, please contact Qingdao Shanfang Instrument. They specialized in tester of fire?rating of external wall thermal insulation materials.

Q: Who knows which chrome refractories produced by the Henan refractory plant can be used for continuous casting?: Chrome drainage sand can be used for coupling process there are many manufacturers do it, this is mainly a lot of chrome, chrome iron ore mainly refers to the drainage sand, adding ladle material amount regulator performance guide. Drainage sand as filling material of ladle bottom nozzle, one hand can be sintered at low temperature, to avoid joining the molten steel drainage sand floating accident, on the other hand, in the high temperature and long time refining steel surface can not meet the state of sintering is too thick, otherwise it will affect the automatic pouring rate, Hua Heng worth a try I'm not favored, my sky is the wind or rain rainbow you hate yourself in the manipulation of really useless emotional heart to still ache for breaking up before the sorry shuttle time in the moving picture of the clock in the opposite direction when the initial time begins to move back to love you

Q: How long is the fire-resistant time of fireproof wooden door?: National standards define the fireproof door as class A, class B, class C, among which fire-resistant time of class A fireproof door should not be less than 1.5 hours, class B should not be less than 1 hour and Class C should not be less than 0.5 hours.

Q: What is refractory cement?: The introduction of properties and chemical composition of refractory cement. Refractory cement usually refers to the cement with calcium?aluminate as the mian compopnent. Refractory cement is a monolithic refractory. It is in particular a basic binder of castable refractory. Its chemical composition is mainly Al2O3 and CaO, and some contain a considerable number of Fe2O3 and SiO2.

Q: Who knows what kind of fire protection material is better?: Characteristic of polyurethane rigid foam thermal insulation decorative composite board: (1) ultra high cost performance, increased property's selling point (high cost performance) new model of thermal insulation material, excellent thermal insulation properties, elegant decorative effect, 50 years of service life, reduce maintenance costs and social waste. (2) it overcomes defects of traditional insulation technology (to solve the freezing and thawing, veneer cracking and shedding) traditional benzene board, the phenomenon of freezing and thawing that is easily appear in plastic extruded sheet, paint finish is easy to crack; its veneer facing can easily fall off; thermal insulation materials and wall are poorly adhered, easy off the whole. There is a themal bridge in dry hanging wall. (the characteristics of polyurethane composite board)
