Q:What is the offer of fire proofing thermal insulation material?
Asbestos fire proofing thermal insulation material Brand/Model: Xintianli Origin: Fujian|Brand: Xintianli Offer: 800.00 yuan Fire proofing thermal insulation material Brand/Model: Jiulong|Origin: Gaoxinzhuang Indutrial Park in Shucheng Town in Hejian City in Hebei Province| Brand: Jiulong Offer: 360.00 yuan. The above prices are from the Internet and for your reference only. Price may vary according to specific circumstances. I hope it can help you.
Q:Who knows about the differences between 3M fireproofing materials and ShiLiDe materials?
ShiLiDe materials are relatively poor, and have nothing to do with 3M at all. 3M is a brand! 3M company is famous for innovation around the world. It has developed a variety of products in a hundred years, involving in automotive, chemicals, telecommunications, construction and other fields. 3M automotive aftermarket has more than 3,000 products (more than 20% of which are high-tech patented products). The world's first explosionproof and heat insulating film, and the first waterproof abrasive paper were born in 3M Company. The abraser, polishing materials, mirror finish of paintwork, the internal and external auto beauty of 3M Company rank the first place in the world. 3M films are divided into conventional films and crystalline auto films. The conventional films of 3M generally have five-layer structure, the base of films is a polyester film which is s plastic film of tearing and puncture resistance. The film is coated with thermal insulation layer, ultraviolet isolation layer, adhesive layer, wear-resistant layer, and protective layer which finally becomes thermal insulation and explosion-proof film with metal sputtering method. Optical micro-attach technology is used in the polyester film which is the base of 3M crystalline auto film. It is coated with more than 240 layers of optical coatings in order to achieve better thermal insulation performance, and be the top anti-explosion and heat-insulating film with clear sight. I hope my answer can help you. Thank you.
Q:What kind of refractory materials are used in the intermediate frequency furnace?The domestic boric acid can be used as a lining?, how much is the rate?
Acid, neutral, basic and composite materials are used in intermediate frequency furnace. Boric acid is used according to the type of steel, the specific ratio is too generalized, and it shall be determined when the type of steel is detailed.
Q:What is neutral refractory? Can refractory suppliers tell the main components of it?
// Baike? Url x3d CQ3i6_yUCWUMgk3aaRGGLURNtvKPl5IdZpj35Yvommk7Nyif0IJD-SkdIW29GCHwLpb9cT9Ii25GLcEJg-ZHcq "target x3d" _blank "x26gt; http://baike.baidu.baidu.
Q:What characteristics do A grade external wall fireproofing material have?
For characteristics of A grade external wall fireproofing material, its main raw material uses cold resistant and thermal insulated, environmental protection and energy saving material with good insulation, keeping the indoor temperature steady and making the environment more comfortable. It is several times better than other masonry in overall strength and resist capability, and it can also hang heavy objects such as air conditioners by directly nailing or installing expansion bolts. Single point hanging machine can withstand heavy objects with the weight of more than 45kg. It can also be directly fixed to the tiles, wallpaper, wooden plaques, paint, etc.
Q:What refractory material lead smelting furnace needs?
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:What are the additives and recipes of refractory?
Add FDN.
Q:I would like to ask a friend that how much is the fire endurance of level A fireproofing glass?
fireproofing glass is mainly control the spread of fire or smoke insulation, and is a measurable fireproofing material, the fireproofing effect is evaluated by the fire resistance. It is through a special process and treatment, and it is a special glass which can maintain its integrity and thermal insulation in the specified fire resistance test. Original glass of fireproofing glass can be used float flat glass, and composite fireproofing glass also can use monolithic fireproofing glass.
Q:What does the function of SiC for refractories?
The main feature is with high temperature, the wear gold resistance of refractory is recognized by our customers. Hope my answer will help you.
