- Q: What materials is silicious thermal insulation board made of?
- Siliceous insulating panels use quartz sand as the main material and are composited with fiber. Of course the amount of insulation board materials used by different companies is different. In terms of Hua Heng, siliceous insulating boards can be divided into insulating panels for casting slabs and insulation board for intermediate tank according to the usage. The latter one can be divided into liner plate (wallboard, side panels, baseboard) and impingement plate based on parts it is used on. Siliceous insulating panels use quartz sand as the main material and are composited with fiber. Method for manufacturing a silicon insulating panel is divided into semi-dry method and wet method. It is used for casting ingot insulation cap of the killed steel and continuous casting tundish.
- Q: How long is the duration of fire resistance that fireproof window of level B can endure?
- Fire proof window of level B is the fire proof window whose duration of fire resistance is not less than 1 hour. Technical requirements: One, Materials and fittings (1) the frame of windows draw on steel or wood frames which have certain intensity and are able to ensure the integrity and stability of components. (2) Steel frame and layering can use galvanized steel or stainless steel plate. Its selection criteria shall be in line with provisions 5.1 of GB12955< steel fire door general technical conditions >. (4) The internal fillings of steel, wood frames should use non combustible materials. (5) Fire proof windows can opt for qualified products without affecting the performance of fire proof window. Light transmittance of glass shall not be less than 75% of the same layer of ordinary flat glass. (6)The sealing material between the frame and the fireproof glass should adopt the nonflammable materials, functioning as the fire blocker. (7)Hardware fittings should be tested for qualified products.
- Q: What are the models of bauxite with high alumina?
- China Ferrous Metal Industry Corporation released the industry standard of bauxite (YS / T78-94) in 1994. According to this standard, bauxite can be divided to sedimentary diaspore, stacked type diaspore and lateritic gibbsite. According to the chemical composition, it can be divided into nine trade marks as LK12-70, LK8-65, LK5- 60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50 and LK3-40. In addition to the provisions of chemical composition of bauxite, the standard also requires that the water of sedimentary diaspore shall not exceed 7% and water of stacked type diaspore and lateritic gibbsite shall not exceed 8%. Moreover, particle size of bauxite should be not greater than 150mm. Bauxite shall not be mixed with clay, limestone and other debris.
- Q: What antioxidant will be used in refractories?
- Antioxidants (Antioxidants) is the material to prevent bad influence of oxygen. It is a kind of material that can help to capture and neutralize free radicals, the category of material to remove free radicals damage to human body. Some of the body's antioxidant is self-synthesis, others is also from the food supply. Strong antioxidant such as ASTA (short for astaxanthin), etc., generally human cannot synthesize and it must be intaked from food. (1)antioxidants in the food can protect food from oxidative damage and deterioration. (2) it has the antioxidant effect in the human body's digestive tract and prevent oxidative damage in the digestive tract. (3) after being absorped, it can play a role in other body tissues and organs. (4)It is derived from certain foods that have antioxidant effect of extract and can be used as a treatment drug. Antioxidant mechanism includs chelated metal ion, scavenging free radicals, quenching singlet oxygen and removal of oxygen and inhibit oxidase activity, etc

According to the shape it can be divided into: Fibrous finishing, mineral?cotton, rock wool, glass wool, aluminum?silicate?wool, ceramic fiber,ect.. it takes the flint clay clinker as raw material, produced by the fusion of resistance or electric arc furnace and the injection of fiber forming. characteristic: Low thermal conductivity, excellent thermal and chemical stability, without binder and corrosive material.
- Q: What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!
- Common faults and causes of magnetic?separator. 1. Motor of magnetic?separator is overheated and its sound is not normal. Reasons for this failure are: 1) lubrication of bearing is bad or badly worn; 2)fan blade falls off or wears; 3)bad contact of switching circuit or disconnected to run a single phase; 4) voltage is too low. 2. Reasons for this failure due to overheated speed reducer are: 1) lack of oil or poor kerogen; 2) wear between gear and worm, or poor mesh; 3)poor lubrication of bearing or serious wear. 3. The sound of magnetic?separator during operation is abnormal, lattice ball mill. Cylinder is stuck by obstacle, and even the cylinder can not rotate. The bottom box vibrates. Reason for this failure is often that it is stuck by objects in drag flask, otherwise magnetic?patch falls off so that the cylinder screaks and pierce tube when it is serious. At this time, car should be stopped for maintenance and troubleshooting. Only when we master common faults and reasons of magnetic separator can we timely identify problems and solve problems. Better maintenance and repair of magnetic?separator equipment are an important prerequisite to properly use equipment and ensure the construction.
- Q: What material is used for making refractory stone bowl?
- Stone pot is carved from high-quality natural refractory stone with a professional way. It has attractive and diverse appearance, and it is hard, heat fast, not stick food. Now it is used in many hot pot restaurants.
- Q: What is the fireproofing requirements of external wall thermal insulation materials?
- in the 2011 and 2012 revised version of "Fireproof? Specification of Building Design" in China, the external insulating layer of above 50 meters (approximately 16 layers) of the housing must use the level A material. The latest draft for approval is not so strict, above 100 meters (about 33 layers) only use level A material. The manuscript of "Building Regulations" is also regulated building's external wall thermal insulation materials in the crowded places should be level A. Except the residential buildings and the buildings in the crowded places, the height of other buildings is greater than 50 meters, combustion performance of insulation materials should be level A; the height buildings is greater than 24 meters but not more than 50 meters, combustion performance of insulation materials should not be lower than level B1. "Building Regulations" manuscript should relax the rules on the aspect of protective coating in level B1 and B2 insulation material. The outer of level B1 and B2 level insulation material must use incombustible?material as protective coating, its thickness is changed from the original 10 cm to 5 cm. Given certain conditions, I feel you can use TDD exterior wall thermal insulation decoration integrated rock wool board for construction, which is level A fireproofing with a short construction period and good thermal insulation properties. I hope I can help you!
- Q: who knows the fire endurance of fireproof coating?
- fireproof coating of different thickness differs in its fire endurance. Let me intrduce you as follows: The amount of time of 0.5 hours refractory thickness 0.45mm 0.79kg / m21 hr 0.9 mm 1.5kg / m21.5 hour 1.4 mm 2.3kg / m22 hr 2.0 mm 3.3kg / m22.5 h 2.8 mm 4.6 kg / m2
