- Q: what's the application of fireproofing abs materials?
- ABS is acronym of Acrylonitrile Butadiene Styrene )it is a kind of thermoplastic high polymer material with properities of high strength, good toughness, easy processing and molding. it has high strength, corrosion resistance, high temperature resistant, so it's often used in the plastic shell manufacture of instruments.
- Q: What are the applications of refractory in petroleum?
- It can be used in chemical filler. For general process, some insulation parts also need to use refractory.
- Q: What is the difference in the nature between the refractory material and thermal?insulation?material
- thermal?insulation?material is used to thermal insulation and the transfer of heat insulation. refractory material is defined as greater than 1580 ° non-metallic materials, such as calcium silicate board. its using temperature can reach to 1100 degrees, and some can also be used at high temperatures, and all high-temperature industrial can't be oprated without it, and the using temperature of polycrystalline alumina fibers can reach to 1800 degrees
- Q: What are the insulation fireproofing materials?
- Insulated shoes, insulated gloves, tape (cloth, plastic, as well as waterproof) yellow wax tube, mouth care, fireproof (ie asbestos cloth is sold by jin) there is pressure-caps black tape, waterproof tape ,casing. There are glass fiber needle felt is widely used in electrical, chemical, construction, transportation, automotive and other industries interlayer insulation and silencer system, and used as an insulating fireproof material.
- Q: Where is refractory used? Thank you!
- Currently, refractory is widely used as inorganic nonmetallic material of production equipment lining in metallurgy, ceramics and other industries. The current definition of refractory does not only depend on whether the refractoriness is above 1,580℃.
- Q: What are the common refractory insulation cotton material?
- High aluminum, clay brick, aluminum silicate fiber module and so on, inorganic types are glass wool, rock wool, foam glass etc.. Organic: the best one is phenolic foam, compround phenolic foam cement layer is a-level. Aerated concrete and other refractory thermal insulation material mainly refers to the inorganic thermal insulation materials and compround thermal insulation material, expanded perlite, foam clay It is applicable for buildings that have high requirement for fire proof level, foamed concrete, volcanic ash glass.
- Q: What's the frequently used refractory material?
- Refractory material is generally used in industrial departments like metallurgy, glass, cement, ceramics, machinery, hot working, petrochemical industry, power and national defense. Frequently used common refractory: silica?brick, semi-silica brick, clay brick, high alumina brick, magnesia brick, etc. Frequently used special refractory: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, calcium oxide, chromium hemitrioxide, alumina, magnesium oxide, etc. Frequently used fireclay insulating refractory: diatomite product, asbestos product, insulation?board, etc. Frequently used unshaped refractory: ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, refractory coating, lightweight refractory?castables, etc.
- Q: Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?
- There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.
- Q: can slag tailings be used to be the base materials of refractory materials ?
- perhaps not, because it has many pores.
- Q: How can the furnace be replaced after the gasifier or water wall is replaced with refractory material?
- The furnace shall be made according to the type of refractory and the moisture content and the type of bond. Pay special attention to the discharge of free water and crystalline water, not too fast to prevent cracks!
