- Q: Who can introduce the difference between galvanized fireproof?coatings and steel structure fireproof materials?
- When the steel surface derusted, it generally needs to brush rich-zinc primer before spraying fireproof coating. Fireproof coating plan itself includes anticorrosion plan, and fireproof coating is just a layer of coating plans, which is an intermediate layer in general. Fireproof coating plan generally includes primer, fireproof coating and finishing paint. Some fireproof coatings can be directly painted on the bare steel elements without primer and finishing paint. Galvanized surface generally is not necessarily needed for brushing fireproof coating. Fireproof and galvanized surface have relatively poor bond strength, so it is advisable to brush transitional lacquer or micaceous iron on the galvanized surface.
- Q: What refractories have good mechanical property resistance and heat expansion and cold contraction property?
- Aluminium oxide ceramics. I would like to know that what kinds of refractory materials can combine together and what kind of masonry way can be used for these materials so as to achieve the perfect combination.
- Q: What are the construction measures of refractory material in winter? Please descriptive briefly.
- The temperature is low in winter, so refractory bulk materials should be stirred evenly on time to avoid freezing.
- Q: I want to know what is the slim in the refractory bricks
- lining brick and refractory clay in the teeming ladle; high alumina brick, high alumina lining brick and high alumina refractory mortar can make cement kiln and glass melting furnace in the building materials industry for anti-slide. Taiyuan in Shanxi province is the famous place of origin; hard paste in the refractory clay is used as blast furnace refractory: // b, in agriculture as a fertilizer high alumina clay is also used in oil wells, which generally do not dip in water; accounting for 2/3 of abrasive products in the metallurgy, hard and semi-hard clay can be manufactured as ceramics for daily use. what you said should be slime. High-alumina clay can be resistant to high temperature after calcination! Refractoriness refractory clay refers that the refractoriness is more than 1580 ℃ with greater hardness and specific gravity and high refractoriness. except higher refractoriness, such as aluminum sulfate, the dosage accounts for about 70% of refractories; refractory clay and high alumina fused cast brick are widely distributed in China.
- Q: Refractories for iron-making blast furnace?
- Vibrating materials, corundum brick and aluminum carbon brick will be developed. Taphole commonly use stemming, silicon carbide - graphite bricks, whose material is Al2O3-SiC-C. Medium and large sized blast furnaces in China use dense mullite bricks, castable, graphite brick. Common lining material for iron ditch is ramming mass. hearth and furnace bottom common use carbon bricks, semi-graphite bricks, charring silica bricks, corundum bricks. Blast furnace bosh and lower part of furnace stack commonly use mullite bricks.
- Q: Can anyone say something about what A-level fire-proof decorative material is?
- The major products are material monomer A-level and composite A-level, now a lot of B-level material is wrapped in calcium silicate board. The foam cement overall composite is level A, such as phenolic aldehyde composite, as well as some of the foam paddings, monomer A-level includes rock wool, ultra-thin insulation panel and the like. But there are few products with real sound A level qualification. Many manufacturers are playing the edge ball with A-level fire rating examining reports and B-level system detection reports and records, but this situation will not last long, which will soon be clear.
- Q: Which brand of refractory fiber hard thermal insulation board is better?
- Thermal insulation materials are divided into two types: porous material and heat reflecting material. The former uses the air void contained in the material to maintain thermal insulation itself for the heat conductivity coefficient of air or inert gas within the voids is low, such as foam material, fibers and other materials; the latter material has a high coefficient of reflection which can reflect the heat, such as gold, silver, nickel, aluminum foil or metallic coated polyester and polyimide thin films. Aerospace industry has strict requirement for the weight and volume of thermal insulation material, and it is often also required to has the properties of noise absorption, vibration attenuation, and anti-corrosion. Different aircrafts have different requirements for thermal insulation materials. Aircraft cabin and cockpit usually use foam, ultra-fine glass wool, high silica cotton to maintain thermal insulation. Earlier missile head uses phenolic foam plastic as thermal insulating material. With the application of polyurethane foam with good thermal endurance, the single insulating material has been developed to sandwich construction. A few millimeters foaming coating is coated on the skin outside the missile instrument bay, it is anti-corrosion coating at room temperature and when aerodynamic heating reach 200 ° C or more, it will generate foam evenly thus maintaining thermal insulation. Artificial earth satellite moves in an environment where the temperature varies from high to low, so it must use laminated thermal insulation material with high reflecting performance, which is usually made up of dozens of layers of aluminum film, aluminized polyester film, and aluminized polyimide film. In addition, the successful development of the surface thermal insulated tiles has solved the problem of thermal insulation of the space shuttle, it also marks a higher level of development of insulation materials.
