Q:How long is the fire endurance of the rock wool board?
In the fire safety rules, of the building materials are classified as non-burning combustion body, difficult to burn the body and burning body categories depending on its difficulty level of burning. Rock wool board is the fiber processed by the coated steel sheet and basalt minerals and other inorganic minerals,and the building panels through artificial composition. Because that the dominant sectors, like, steel plate and rock wool are non-combustible materials, so it should be considered as non-combustible component. The fire resistance of rock wool board has its judging criteria. Loss of support capacity, loss of integrity and loss fire insulation function. Its fire resistance is within 2 hours.
Q:Does anyone know the refractory temperature of fire-resistant glass?
Ordinary glass will burst under sharp temperature difference of about 70-120 degrees and toughened glass of 200 degrees. It is not yet clear for the bursting temperature differences of the refractory glass. If the overall glass is heated evenly, it will have no significant change below 600 degrees, and it will deform with the increase of temperature until melting. The fire-resistant time of the glass you said is the time to heat the glass into the extreme temperature differences it can endure, which should not be more than 10 minutes
Q:Who knows about the differences between 3M fireproofing materials and ShiLiDe materials?
Advertising materials can be divided into fireproofing and non-fireproofing ones which can not tell the differences with naked eyes. You can ask 3M to provide test reports or go to a the third party test organization SGS to do flame retardant test, maybe I can help you. Mineral wool board is harmful to human body, will lead to chronic poisoning, the quality of it is bad! You must pay attention to it! It can not be used in chemical and pharmaceutical plants.
Q:Which refractory is better for building 1500 degree kiln ?
The top and wall use alumina hollow ball brick. If it is cubic kiln, the kiln bottom should use heavy corundum brick. If it is continuous kiln, burning zone should use alumina hollow ball brick, burning zone seal and kiln car face brick. If it is pit furnace, curved seal should use heavy corundum brick, and furnace wall and top should use alumina hollow ball brick. That depends on what kind of kiln it is. Curved seal and kiln car should use heavy corundum brick. You can add me friends to have further talks.
Q:Is fireclay poisonous?
Refractory materials are typically oxides, alumina, magnesium oxide and aluminate cement and etc, which are non-toxic.
Q:What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!
What are the requirements of granularity of material?
Q:what's the varieties of thermal insulation material with A level fire rating?
the main A level fireproof material is rock wool now (note:it is rock wool not mineral wool). A1 level fireproofing, now the largest producer is Taishi rock wool Co., Ltd.; hope my answer can help you, thank you.
Q:Can anyone tell me which materials are fire-proof high temperature resistant material?
Fireproof high temperature resistant materials such as: Quartz, tridymite, cristobalite, chalcedony, flint, opal, quartzite, White silica sand, diatomaceous earth, the silicon oxide (SiO2) contained in these siliceous materials is at least 90% . The silicon oxide in some pure raw material can be above 99 %. Siliceous materials are acidic in high-temperature chemokinesis. when existing metallic oxide or contact with metallic oxide, they will conduct chemical actions and conbine into fusible silicates. Therefore, if the siliceous raw material contains a small amount of metal oxide, its heat resistance will be seriously affected..
Q:Is there a worker in (Jigang refractory plant)?
Ha ha, base should be rest, you won't give you money, Hugh or those money, endlessly is your dedication. Should be double cease, ah, how do you say four days?. In theory, it's five days off now, and the three day of that is from the chairman to every employee.
Q:What is the role of adding chromium oxide green in unshaped refractory materials
Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.
