Q:Are the specification of fireclay bricks and ordinary clay brick the same?
Do you want to know whether the specifications of fireclay bricks and ordinary clay brick are the same?
Q:What materials are needed to make the amorphous refractory bricks?
Amorphous refractory bricks have good quality, good reputation, complete in specifications,high refractoriness, strong resistance to slag, and long service life. It’s worthwhile.
Q:Is the ball mill used in production of refractories?
Refractory is a kind of non-metallic material that is of resistance to thermal shock and chemical erosion, low thermal conductivity and low expansion coefficient. The refractoriness of the refractory is not less than 1580℃. The usage of the refractory is broad. Refractory materials include refractory bricks and powders. Abandoned refractory bricks can be recreated as new bricks after they are crushed by a crusher and grinded by a ball mill. The ball mill and crusher are needed to grind and crush the material in the production of the refractory. The ball mill produced by Zhengzhou Xinhai Machinery Manufacturing Co. has excellent performance and there are many successful cases in Inner Mongolia, Heilongjiang and Guangdong. At the request of the national environmental policy, the company adjusts the equipment details, allowing the equipment to ensure the volume of production while reduce energy consumption.
Q:What is the function of refractory in ceramics?
It depends on what purpose you want to achieve. At the same time, part of special ceramics belongs to refractory. If is is to produce ceramic products, the aforesaid answers are very comprehensive.
Q:What are some of the new refractories and what are their characteristics?
Alumina, a better refractory material, is a new type of ceramic refractory, the characteristics are unclear.
Q:I wanna ask about the thermal insulation material fire resistant level?
The inorganic glass wool, rock wool and foam glass. Organic: The best is the phenolic foam, phenolic foam composite cement layer is level A.
Q:what's the fire endurance of fireproof panel?
fire endurance of fireproof panel can reach 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.
Q:Can the teflon material resist fire?
It is belonged to the fire retardant materials. By UL-V0 grade
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 refractories are accessible with ease in daily life?
Basically there have all materials. But it depends on your needs.
