- Q: What materials is silicious thermal insulation board made of?
- Refractories that contain more than 93% of the monox are acidic refractory materials which include ordinary silica brick, high-density and high-purity silica brick, silica brick that contains chromium, fused quartz products, unburned brick and siliceous ramming materials. It has good softening temperature under a fixed load and can resist corrosion of acid slag, but will have chemical reaction with alkaline slag. Silicious refractory of industrial value mainly is crystalline quartz, such as α and β quartz, tridymite and cristobalite.
- Q: Who knows the refractoriness of high temperature lightweight firebricks?
- Refractoriness refractory bricks with different melting points, the melting point is liquid and solid crystal phase at a temperature equilibrium. The vast majority of bricks are made of heterogeneous materials. No fixed melting point, it begins to appear to be melting and becomes complete liquid gradually, solid and liquid coexist over a wide temperature range, fusion and softening of refractory is messured by its performance at high temperature. Therefore, refractoriness is the temperature at which the multiphase reaches a certain degree of softening. Refractoriness is an important technical indicator in evaluating refractory bricks, but it can not be seen as the temperature ceiling. GB / T 7322 "Test Methods for high alumina brick refractoriness" alumina brick refractoriness test standards. refractoriness of some commonly used refractory bricks as follows: 1, clay brick 1610? 1750 ℃ ??2,silicon brick 1690? 1730 ℃ 3, crystalline silica 1730? 1770 ℃ 4, hard paste1750? 1770 ℃ 5, high alumina brickx26gt; 1770? 2000 ℃ 6, magnesite refractory bricksx26gt; 2000 ℃ 7, dolomite refractoryx26gt; 2000 ℃
- Q: How can refractory materials be divided?
- Refractory materials in China can be roughly divided into refractory products and unshaped refractories.
- Q: which kind of material should be used in fireproofing cabinet?
- Natural stone,marble. advantage: Colorful, soft texure, natural and diverse texture, easy to cut or engraving molding. Disadvantages: Because it is a natural formation, tiny loose crackle is easily folded, because the stone is porous material structure, if sewage and waste water permeate in the structure in the process of production, transportation or construction, it's difficult to clean and easy to crack. In daily cleaning, it is inevitable that there will be some residue left, and dirt is filled into crack under the wiping of rag and becomes a breeding ground for bacteria. 2, granite. advantages: Granite has big density and high hardness, with wear-resistant surface, it's one of the most common materials for family decoration. Compared with natural marble, it can be used in the materials of kitchen countertops, and granite has good anti-bacterial regeneration ability. Disadvantages: As the cabinet table material, natural stone is usually not very long, so in order to produce a long overall table (especially U-shaped, L-type table), it will certainly exist joints, which are also easy to hide dirt. 3, artificial stone. advantages: Artificial stone has richful lines and colors, and it can be comparable to stone, it's non-toxic, non-radioactive, easy to clean, and can be truly seamless splicing. it belongs to economic environmentally friendly material. Disadvantages: Artificial stone belongs to the processing industry, and has low technology requirements, The inferior products of many small companys are fulled in the market and damage customers' interests. There exist faded color,poor aging resistance,oil stain and other issues in affordable products.
- Q: How long usually will the A-level fireproof materials prevent the flame?
- A-level fireproof materials refer to the materials which are made of non-combustible materials, it is a different concept from fire resistance. non-combustible elements: Components are made of non-combustible materials. Non-combustible materials refer to materials that will not burst into flame, and burn as well as be carbonized when affected by fire and high temperature in the air. Fire resistance: Having a fire resistance test on any building components -----according to the standard time-temperature curve. This period starts from the time when affected by fire and ends up with losing the ability to support or to insulate fire or the integrity of the components. It can be expressed in hours.
- Q: How to choose refractory material
- The crystalline refractory fiber mainly consists of polycrystalline mullite fiber, the optimum use temperature is 1300 DEG C, and the long-term use temperature of polycrystalline alumina fiber is 1400 DEG C. The service temperature of ordinary refractory fiber is 1150 degrees, and the use temperature of advanced refractory fibers (such as alumina, zirconia, refractory fiber) can reach 1700 degrees centigrade
- 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: Which fireproofing materials factory is the best in Xiangyang?
- Xiangyang Shenglaide Door Technology Co., Ltd. Location: Taibai Road, Fancheng District, Xiangfan, Hubei Province Xiangyang Ai'ruite Door Technology Co., Ltd. Location: Scientific and Technical Pioneering Park, Xiangcheng District, Xiangfan, Hubei Province Xiangyang Innovation and Ideal Manufacturing Co., Ltd. Location: Xiangyang Xiangfan state Jianshe Road, Xiangzhou District, Xiangyang, Hubei Province
- Q: I wanna ask about the thermal insulation material fire resistant level?
- The inorganic have glass wool \ foam glass Bian \ the best of organic is phenolic foam \ phenolic foam composite cement layer is level A.
- Q: What is the the best ratio of mortar in refractory cement?
- Specifical proportions are as following: 42.5R cement is 425 rapid hardening cement. Using the 425 cement to compound the mortar. The reducion of cement will naturally impact the workability of the mortar. The mix design standard of the mortar specifies the minimum amount of cement is not less than 200kg / m3. If it is composite mortar, and the strength and workability can be ensured, it is Ok to use 425 to compound. You can look for instructions of mixing proportion of mortar online as a reference.
