- Q: What is acid refractory material?
- Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, there are refractories for special occasions. Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 93% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, low thermal shock resistance. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used. Neutral refractory is mainly composed of alumina, chromium oxide or carbon.
- Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
- Strictly speaking, as long as there are solid wood packaging, you need to do fumigation inspection, proved not necessarily used, there are IPPC chapters on it.
- Q: what are the requirements of fireproofing material?
- The producing process of fire and moth proof wood: firstly, put general wooden materials into solution with calcium, aluminum and other cations, then soak it into the solution with phosphate radical, silicate and other anions. Thus, the two ions will be carried out chemical reaction in the wood, forming a ceramic-like material, and intimately fill the voids of cells, so that the wood has the fireproofing and mothproof properties.
- Q: What are the insulation fireproofing materials?
- Asbestos is the most common. Asbestos containing zirconium and made of the mixture of zirconium aluminum and silicon through wire drawing is better. Of course, some are made directly from natural things which can withstand 1400 degrees for over 30 seconds while the internal temperature had no significant change, and withstand 1400 degrees for over five minutes while inside temperature increase does not exceed 5 degrees.
- Q: What high-molecular polymers can be used as fire-resistant material binder?
- Melamine resin should be compounded with fire-resistant material and acrylic acid material is easy to burn. But high-molecular polymers can be used along with the above two. Polysulfone is featured by heat resistance and high temperature resistance. Polyurethane is difficult to process and compound with fire-resistant material. Phenolic resin is not easy to burn. Epoxy is expensive and self-extinguishing once away from fire.
- Q: How should fireproof building materials be ranked?
- According to our national standard GB8624-97, the combustion performance of building materials are divided into the following levels: A class: Incombustible building materials: the material is almost incombustible. B1 class: Flame-retardant building materials: they are better in fire retardation. It is non-combustible when meeting open fire in the air or under high temperature, and it is difficult for the fire to spread quickly. Besides, when the fire source is removed, combustion stops immediately. B2 class: Combustible building material: It has certain fire retardation. In case of open fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as the spread to wooden pillars, timber roof truss, timber beams, wood stairs, etc. B3 class: Flammable building material: It has no fire retardant effect at all, but is highly flammable with high fire risk. Hope my answer can be accepted.
- Q: How to choose construction external wall thermal insulation and fireproofing materials?
- The width of fireproof partition shuld be greater than 30CM, and the thickness should be the same as total thickness of thermal insulation materials. Fire barrier zone thermal insulation board and base wall should be stuck in whole area. Fire Barrier zone thermal insulation board should be stuck with the assistance of anchor bolt which must press the mesh of the bottom layer. Fire Barrier zone should be set above the door and window, with a distance of less than 50cm between the lower edge of fire barrier zone and the upper edge of window.
- Q: The manufacturing technique of refractory material
- Melt blowing method is to melt the ingredients first, In addition, hiphotos, organic impurities, to be mixed, add sulfite pulp waste liquid into magnesia billet , ensure the accuracy of the product dimension. The products are mainly used for light refractory. then dry and fire with sintering to reduce the firing shrinkage of products, making it disperse into fiber or hollow sphere. The porpose of pre sintering raw material is to Sintering method is pre-sintering part of the raw material into clinker. such as adding binding clay into aluminum silicate blank
- Q: What is the mechanism of the errosion of the iron to the refractories?
- For example, the effect of the iron oxide: Mo corundum given temperature Fe2O3 solid solubility limit of the solid solution formed of corundum stone high solubility than the solid solution Mo Mo corundum lattice shape so Fe2O3Al2O3-SiO2-based material starts melting temperature of the system or the content of Al2O3 and Al2O3 / SiO2 ratio off Al2O3 / SiO2 & lt; 2.55 starting melting temperature of 1380 ℃ when Al2O3 / SiO2 & gt; 2.55 start melting temperature is increased 1460 ℃ and with its Al2O3 content increased gradually to increase the original atmosphere Fe2O3 original FeO off the solvent into the glass phase and the system starts melting temperature drops do not fall to 1240 ℃ 1380 ℃. Lower the melting point, increase the erosion, and reduce the life span.
- Q: Who knows about the B-level fireproof insulation materials?
- Organics, extruded sheet, polyphenyl board and phenolic resin. The fireproof?performance of sea capacity module (fireproof and thermal insulation material) is B1-level with the heat conductivity coefficient of only 0.028w / m · k. It is a good choice. A-level: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic aldehyde, and foam glass. B-level: Rubber and plastic, extrusion molding, polyphenyl, PEF.
