Q:What occupational hazards should be detected in glass ceramic and refractories industry?
Q:What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?
The thickness of steel structure fire retardant coating hasn't been regulated in the steel structure application specification (CECS24:90). The above thickness refers to a certain thickness that must (at least) achieve a certain time of the fire resistance. The thickness of fire-retardant coating in engineering is generally determined according to factory inspection report. We use thin steel structure fire retardant coating: 2.5 hours' fire resistance with the thickness of 4.9 mm; 2.0 hours' fire resistance with the thickness of 3.5 mm; 1.5 hours' fire resistance with the thickness of 1.75 mm; 1.0 hours' fire resistance with thickness of 1.17 mm. I hope I can help you.
Q:What is shapeless refractory?
Q:What's the requirements of fire-fighting criteria of heat insulating material?
It shouldn't be under than B2 level. Roofing insulation fire rating requirements: the ministry of public security, housing and urban-rural development department issued about printing and distributing the civil building external thermal insulation system and the interim provisions on the exterior wall decorative fireproof prescribed in the notice: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm.
Q:Who knows the roofing fireproofing and waterproof material?
If you should do home water proofing, I recommend the acrylate waterproof coating with high elasticity of Qinglong waterproof, because it has good aging resistance, extensibility, elasticity, binding property and film-forming property; waterproof layer is a closed system, the overall waterproof effects are very good, especially for the construction of heterotypic structure base and roofing, walls, toilet and bathroom, basement and other buildings waterproof and anti-seepage engineering in the conditions of non-permanent immersion;
Q:Procedures for producing common refractory materials?
The general procedures of producing refractory materials include calcination of raw materials, selection of raw material , crushing, grinding, screening, mixing, ageing mixture, molding, drying, burning and etc. At present, the refractory factory usually purchases the calcined clinker, so the calcination of raw material is no longer a consideration of common refractory plants.
Q:What are grades of refractory materials?
Refractories have lots of varieties which all have different purposes.1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ to 1770 ℃, advanced refractories: 1770 ℃ to 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler.
Q:How much is the content of boron carbide in refractory material?
Is it available to iron materials?. Answer: It can be applied to all products, what you need is just a general proportion. Nevertheless, you’d better tell me what product it is exactly.
Q:Who knows what is the standard of insulation material whose fire proof is level A?
Fire insulation materials of level A is non combustible building materials, and does not have any burning material. Level A1: single inorganic non combustible, no open flame. Level A2: A2 level: composite organic non combustible, that is, composite materials, non flammable, smoke volume should reach the standard.
Q:What is the criterion of entry of refractory clay industry?
There are two requirements: (a) Enterprises mining and processing high-alumina clay meet the national industrial policy, and in line with the requirements of mineral resources planning and industrial planning, industrial development planning of high alumina clay in provinces (autonomous regions and municipalities), urban planning, the whole land use planning, mineral resources planning, environmental protection and pollution prevention planning. (b) The building of new mines of high alumina clay in areas where exploitation of mines are restricted in national and local level should be strictly limited. It is prohibited to build new mines in areas where exploitation of mines is banned, and the mines have been built should be disposed in accordance with the mineral resources planning and relevant national regulations. It is prohibited to build high-alumina clay production and processing enterprises in special conservation areas such as drinking water source reservation areas, natural reservation areas, scenic reservation areas, ecological function reservation areas, basic farmland reservation areas, cities and their suburbs, residence, schools and kindergartens, health center, hospitals and perimeter 1 km from enterprises having high requirements on the environment such as food, medicine, electronics etc., the both banks of main rivers and roads, somewhere near trunk railways.
