Q:What are the main characteristics of the sic refractories?
The physical properties of SiC refractories include structural properties, thermal properties, mechanical properties, usability and job performance. The structural properties of refractory include porosity, bulk density, water absorption, air permeability, an the distribution of pore size. The thermal properties of refractory include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity, and thermal emission rate. The mechanical properties of refractories include withstand voltage strength, tensile strength, anti bending strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength, and elasticity modulus. The usability of refractories include refractoriness, load softening temperature, linear change on reheating, thermal shock resistant performance, slag resistance, acid resistance, alkali resistance, hydration resistance, corrosion resistance to CO, conductivity, and inoxidizability.
Q:What's meaning of CN of fire-resistant material?
The commonly used preparation methodsinclude shock compression, high-pressure pyrolysis, ion implantation, reactive sputtering, plasma chemical vapor deposition, electrochemicaldeposition, ion beam sputtering, , low-energy ion radiation, pulsed arc discharge,pulsed laser inducing, etc. But the compounding result of superhard materialis not ideal due to deposition of amorphous CN film, nanometer level sizedC3N4 crystalline grain set in the amorphous film and few large graincrystal.
Q:what is the requirements of roofing insulation materials fire rating?
The fireproofing requirements of architectural design are regulated by architectural design fire safety rules, roofing insulation material only has the requirements of materials combustion performance, namely non-combustible material. No fire rating requirements.
Q:What's the material of fireproof and wear-resisting floor?
Hello! Fireproof floor is non-flammable, wear resistant, and beautiful. It is made by construction steps and has many advantages: seamless, environment friendly, non-toxic, resistant to abrasion and corrosion, waterproof, dustproof, beautiful in appearance with integriality and no irritating odor The material of fireproof floor is in the form of liquid which will be in the shape of solid membrane after the completion of construction. It can be widely applied to the ground in the factory, residential ground or walls, and large areas like institutions and warehouses with high requirement on fire prevention. It can also be used in the field with no requirement on fire protection for it is beautiful in apperance and just like epoxy floor, and with good cost performance, it is a kind of commonly used decorative material. Hope it's helpful for you!
Q:Which kind of external wall fire barrier zone material is better?
I recommended foam cement and particulate thermal insulation composite waterproof material, which is fire isolation area product, which uses surface of vertical plate arranged fiber technology to make the compressive strength in the vertical direction up to above 80KPa. At the same time, under the conditions of both exterior heat insulation and effects of humiture in the long-term, it can still maintain the non-aging performance of various aspects, and safety (reliability), fire resistance and excellent durability.
Q:What material is used for making refractory stone bowl?
Good refractory stone pot is carved from high-quality natural refractory stone in a professional way. But many are also made of synthetic materials, the price is lower, too.
Q:how long is the fire endurance of plasterboard?
Plasterboard is non-flammable B1 level products. There are introductions in Fireproof Specification of National Standard Building Interior Decoration Design. Plaster board mounted on steel stud can be used as A level decoration materials. In accordance with the national fire safety rules on fire durance of walls and ceilings and other components, we can not simply say whether a piece of gypsum board can meet the requirements. In GB "gypsum board" it clearly states: Fireproof plasterboard can endure fire longer than 20minutes. Wherein Dragon brand fire-resistant gypsum board can endure fire longer than 40 mintues. Gypsum board is comprised of dry wall, steel stud and various auxiliary materials. the fireproof performance of the gypsum board system is relevant to the type, quality , layers of the gypsum board, quality of keel and installations, whether the rock wool is filled and its unit weight, the treatment of seaming and some minor joints.
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 special refractories?
Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use
Q:What kind of materials are needed to make refractory bricks?
According to requirements, there are different materials, acid refractory material, such as silica bricks; neutral refractory material, such as high alumina brick; and basic refractory material such as magnesia brick.
