Q:Does anyone know what is a lightweight refractory material?
Heat preservation and insulation layer used only for Thermal Equipment has poor wear resistance, loose organization and high porosity(40%~85%) . The definition of light refractory material: low thermal conductivity, good performance in thermal insulation , weak mechanical strength, low volume density(generally below 13).
Q:In entering fire door, which material does well?
Now generally do stainless steel.
Q:What are the specifications of fireclay bricks?
1. The various classification criteria of clay bricks. First, according to the physical and chemical indicators, they can be divided into these types: (NZ) -42, (NZ) -40, (NZ) -38. Second, the classification of specifications of clay bricks is in line with the stipulations in "general shape and size of refractory bricks". Finally, according to the stipulations of relevant state departments, the clay bricks can be divided into standard bricks, ordinary bricks, special-shaped bricks, special bricks. Second, level of refractory temperature of refractory bricks The refractoriness of refractory bricks is divided into four levels according to changes of alumina content. We know that the components in clay bricks include Al2O3. Alkali metals are also included. The refractoriness of AAA-level clay bricks in Ruitai Refractory Material Factory is 1750 ℃; A-level bricks is 1730 ℃; B-level bricks is 1670 ℃; and C-level bricks is 1580 ℃. The softening temperature under a fixed load of Clay bricks is about 1350 ℃. Clay bricks, also known as sintered bricks, are small size artificial bricks for modern architecture. Clay bricks have good properties and high thermal stability, in which Fe2O3 content is less than 2.0 to 2.5%. Overall dimensions: 230 * 115 * 65mm
Q:Which brand of refractory fiber hard thermal insulation board is better?
Luyang ceramic fiber semi-hard board is good for it has typically applied major technological performance industrial furnaces backing, wall lining, lining material, electric heating furnace backing lining heat insulation ceramics shuttle kiln, backing lining of tunnel kilnand roller kiln.
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:How many types of fire-resistant material?
1. Acid fire-resistant material refers to one with more than 93% SiO2. It is featured by resistance to the corrosion of acidic slag ad high temperature and easy to react with alkaline molten slag. 2. Alkaline refractory material generally refers to one with magnesium oxide or magnesium oxide and calcium oxide as the main component. It has high refractoriness and strong resistance to basic slag. 3. Silicate aluminum refractory material refers to one with SiO2, Al2O3 as the main component. According to the content of Al2O, it can be divided into three categories: half siliceous (15-30% Al2O3), clay (Al2O3 30 ~ 48%), high aluminum (more than 48% of Al2O3). 4. Fused cast refractory material refers to shaped refractory products made by high temperature melting and casting.
Q:I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
which level is b1 fireproof and thermal inuslation matertial: I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire retardant. The wholesale of all kinds of thermal insulation material and construction needs to look at the name.
Q:What advantage and disadvantages it has compared to common fire insulation materials
Generally speaking, high fire resistance, non combustible Various standards for evaluation varies according to different types, which includes anti-corrosion, acid and alkali resistance, waterproof, anti termites and so on. I hope my answer can slove your problem
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 a blast furnace refractories generally?
Common refractories often use silica brick, semi-silica brick, fireclay brick, high alumina brick, magnesia brick, etc. special materials often used are AZS brick, corundum brick, directly bonded magnesia-chrome brick, carborundum brick, silicon nitride bonded silicon carbide bricks, nitrides, silicides, sulfides, borides, carbides and other non-oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide refractory insulating refractory frequently used. material diatomite products, asbestos products, insulation boards. monolithic refractories have fettling frequently used, refractory ramming mixes, refractory castable, fire-resistant plastic, refractory clay, refractory gunning refractory projection material, refractory coatings, lightweight refractory castable, stemming etc.
