Product Description:

Mica Tape consist of phlogopite mica paper (or synthetic mica paper) impregnated with special silicone resin and glass fiber cloth
(or Polyethylene film) as supporting agent. These tapes have great flexibility and high tensile strength, and their combined
characteristics mean they can be used to create inorganic, fire-resistant insulation for electrical cables.

Our high quality mica tape classified 4 types as follow:
◆ST-MG: Single side reinforce phlogopite mica tape with glass fiber cloth ( Phlogopite Mica & Glass fiber cloth)
◆ST-MP: Phlogopite mica tape with PE film on single side (Phlogopite Mica & PE)
◆ST-CG: Single side reinforce calcincated muscovite with glass fiber cloth (Calcincated mica& Glass fiber cloth)
◆ST-SG: Single side synthetic mica tape with glass fiber cloth ( Synthethic mica & Glass fiber cloth)

◆ Thickness:0.08mm-0.15mm
◆ Width:4.5mm-1000mm
◆ Length:300m 500m 1000m 2000m
◆ Standard cores:52mm 54mm 76mm 120mm

Q:What requirements should refractory materials meet?
Ladle is an necessary equipment to undertake molten steel and continuous casting. As many kinds of steel needs to be processed in the ladle, including argon blowing tempering, alloy composition fine-tuning, refining dusting and vacuum processing, working conditions of the ladle lining have worsened. Their working conditions are as follows. (1) The temperature of molten steel is higher than mold casting ladle. (2) the molten steel stays longerin the ladle. (3) ladle lining are subjected to volatilization and agitation of molten steel under high temperatures and in vacuum. (4) The impact on the lining when undertaking steel liner when the impact effect. Therefore requirements of the ladle refractories are as follows: (1) It can resist high temperature. Molten steel should be able to withstand high temperatures without melting. (2) It can resist thermal shock and can withstand molten steel without cracking and spalling. (3) It can resist slag erosion. The ladle should be able to withstand the erosion of lining caused by slag and alkalinity changes of slag. (4) it should have sufficiently high temperature mechanical strength to withstand the agitation and scouring of molten steel. (5) lined should have certain swelling property so that lining will be united as a whole under the effect of hyperthermal molten steel.
Q:Urgently!! Refractory problems, online, etc.
The service life of most refractory materials is a pair of contradictory effects. As a result, one aspect of the contradiction is porosity, and the other is volume density. The larger the volume density is, the smaller the porosity is and the more erosion resistant, but the thermal shock effect is very poor. The bigger the porosity is, the smaller the volume density is, the better the thermal shock effect is, but it is not resistant to erosion. More professionally, two curves should be made to find the intersection of the curves to adjust the recipe and production process
Q:How to divided the grade of external wall thermal insulation materials?
Synthesized the three versions of GB8624 (1997,2006,2011), external wall thermal insulation fire rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indicators to make specific division, but I partly cannot report for a while, because it is very professional and technical. I hope I can help you!
Q:Do you know the refractories?
The so-called main component refers to the first phase and the second phase component, and the content accounts for about 90% of the total chemical composition. The development of modern technology more and more number of refractory material ingredients, so the second phase, the third phase component, adjusting the second phase, the third phase composition can generate a new technology in the chemical composition of the first phase beyond the limitations of the classification, a classification method is the most commonly used.
Q:How to deiron refractory?
Deironing refractory can take physical methods into consideration, such as magnetic separation, reselection, etc. And it can also take chemical methods, such as flotation.
Q:What is the upper temperature limit for refractory materials?
The key depends on what refractories you use
Q:How many kinds of refractory materials are there in the EI?
I suggest that you contribute articles to foreign SCI journals for the odds are better, and generally the articles that fill the bill will not be rejected. The traditional refractory materials can contribute to EI journal. If being rejected by EI journal, you can also contribute to Russia's journal Industrial Ceramics and Refractories. I didn't contribute to the Journal of Wuhan University of Science and Technology, the receiving cycle is almost 3 to 4 months. Though the impact factor is low, domestic EI journal is not so good, it is still SCI journal. This is my own experience, please take my advice. The best journals are the Journal of the American Ceramic Society and the Journal of the European Ceramic Society, I heard that they are not bad. But the best domestic EI refractory material journal is the Journal of The Chinese Ceramic Society. It is very long, but if it belongs to your university, it is another pair of shoes. Journals now all want to have materials about functional ceramics, and they don't want Chinese articles, if your English is not well enough, you can choose Ceramics International and Japan Ceramics but they have strict manuscripts reviewing standards.
Q:What kind of refractory materials are used in metallurgy industry?
Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.
Q:How to divide the fire resistant level of construction thermal insulation materials?
1, Combustion performance of the national standard building materials are divided into the following levels: Class A: incombustible building material: Material that almost never burn. Class B1: nonflammable building material: Nonflammable materials have good effect of flame resistance. In case of fire it in the air or at high temperature it is difficult to catch fire and spread, and when the fire source is removed, the combustion can stop immediately. Class B2: combustible building material: Combustible materials have good effect of flame resistance. In case of open fire in the air or at high temperature, it will immediately burst into flames and spread the fire quickly, such as wooden column, timber roof truss, wooden stairs, etc. Class B3: flammable building material: No flame-retardant effect, highly flammable, high risk of fire. 2, According to fire rating, external wall thermal insulation materials can be divided into 1) thermal insulation material with class A combustion performance. Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite,etc. 2) thermal insulation material with class B1 combustion performance: Extruded polystyrene board (XPS) after special treatment /polyurethane (PU) after special treatment , phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) thermal insulation material with class B2 combustion performance: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:Who knows about the criteria of fireproof and thermal insulation materials?
Seven levels are divided according to "The classification of combustion performance of building materials and products", namely, A1, A2, B, C, D, E, F. It mainly refers to the combustion performance of materials. You can check on this standard for the specific dividing evidence. There are detail charts which mainly describe that whether there is drip or not, the ignition time, continuous burning time and so on.
