MICA TUBE
Mica tube is formed by muscovite paper or phlogopite paper fixed with silicon resin, and processed by roll form.
It has good dielectric capability and excellent mechanical strength, and often used as the insulating tube form material in all kinds of
electric equipments, motors, furnaces, electric-arc furnaces, other metallurgy industry equipments.
Mica tube is 10~1000mm length, the internal diameter is 8~300mm. Special size and tolerance can be determined by agreement.
TOLERANCE OF MICA TUBE
Length: 10mm to 1000mm
Internal diameter: 8-300mm
Density: 1.7g/cm3 to 1.8g/cm3
- Q: What are the materials of white firebricks?
- They are made of baked refractory materials with pale yellow and a little brown on the surface and very cheap. They are mainly used to pile up smelting furnace and can withstand high temperature from 580 degrees Celsius to 770 degrees Celsius. While the firebricks, also called refractory bricks by others, have a certain size and shape. They can be classified according to manufacturing process, namely, the unburned bricks, burnt bricks and electrically fused bricks. Also they can be divided into common bricks, standard bricks and specific bricks according to different size and shape.
- Q: What are the requirements of refractory temperature of refractory brick?
- Oxygen fluctuation of load once happened during operation. Sometimes oxygen control valve will cause oxygen fluctuation of load, and sometimes large particles will block valve of high pressure coal slurry pump. The sudden drop in flow of coal slurry may cause relative excess of oxygen. Oxygen fluctuations directly cause fluctuations in furnace temperature. The range of oxygen fluctuations is 500m?-600m?. The maximum can reach about 1000m?. A sudden increase in oxygen causes a sudden increase in furnace temperature, which will suddenly burn out high-temperature thermocouple. The situation has a great influence on refractory brick and should be avoided. Furnace temperature is very inportant to life of lining of refractory bricks, so it should be strictly controlled not to overheat. There is a cinder layer on the surface of refractory bricks under the condition of normal production. In fact, cinder layer is dynamic. If the temperature is low, cinder layer is thick. If the temperature is high, cinder layer is thin. Appropriate cinder layer may slow the scour of high temperature gas and molten slag. The requirement of refractory brick is higher than that of stoves which use heavy oil as raw material. The main reason is permeability and corrosion of molten slag to refractory material. When replacing refractory bricks, it is found that penetration thickness is 10mm-20mm. After slag penetrates, strength decreases significantly. If temperature is high, erosion intensifies. According to the relevant information, when the operating temperature exceeds 1400 ℃, etching effect multiplies.
- Q: What is molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?
- Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)
- Q: I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
- What you said is the pixel! Only that has b1b2. Level b1 is the fireproofing level b1, because the particle does not belong to the fireproofing material. Only can fire?retardant. The wholesale of all kinds of thermal insulation material and construction need to look at the name.
- Q: What are the insulation fireproofing materials?
- Insulated shoes, insulated gloves, tape (cloth, plastic, as well as waterproof) yellow wax tube, mouth care, fireproof (ie asbestos cloth is sold by jin) there is pressure-caps black tape, waterproof tape ,casing. There are glass fiber needle felt is widely used in electrical, chemical, construction, transportation, automotive and other industries interlayer insulation and silencer system, and used as an insulating fireproof material.
- Q: Does refractory belong to metallurgical auxiliary materials?
- Refractory includes metallurgical auxiliary materials.
- Q: what needs to be noted when choosing and using blast furnace fireproof materials?
- Hello,: three parts of the blast furnace lining in general are easily corroded. The first one is furnace bosh,second is the middle part of the furnace, The third is lower part of the furnace stack. if These parts are damaged, then we need an overhaul. Bosh, because damage to the middle part of the furnace and the furnace bosh are generally due to alkali metal and fusant erosion. the main reason for the lower furnace part damage is molten iron, slag. In view of this situation, mullite bricks, corundum bricks, silicon carbide bricks are used for reparation. make repairments as soon as possible if any problems occur in case of incidents.
- Q: What kinds of fireproof materials does the safe use?
- Copper is one of the most widely used material in safe, for its good mechanical performance, corrosion resistance and processibility and it has beautiful color. Especially handles, locks and other decorations forged of copper are smooth, pore-free, also they have good density, and no blisters. They are solid and rust-proof, which can get gilded with 24K gold or gulch-gold and have other surface treatments. A lot of colors have been added to people's home for the copper's magnificence and nobleness.
- Q: Who knows what kind of fire protection material is better?
- Characteristic of polyurethane rigid foam thermal insulation decorative composite board: (1) ultra high cost performance, increased property's selling point (high cost performance) new model of thermal insulation material, excellent thermal insulation properties, elegant decorative effect, 50 years of service life, reduce maintenance costs and social waste. (2) it overcomes defects of traditional insulation technology (to solve the freezing and thawing, veneer cracking and shedding) traditional benzene board, the phenomenon of freezing and thawing that is easily appear in plastic extruded sheet, paint finish is easy to crack; its veneer facing can easily fall off; thermal insulation materials and wall are poorly adhered, easy off the whole. There is a themal bridge in dry hanging wall. (the characteristics of polyurethane composite board)
- Q: what is steel fire door made of ?
- 1. fire resistance steel door has steel made door frames, door leaf framework and door panels. if the door leaf is filled with nontoxic fire insulation material, added with fireproof hardware accessories, which consists of a door that is fire resistance.
