Q: What is the density of ceramic fiber modules? The best insulation effect: Ceramic fiber module density is only a standard in the world, is 220Kg/m fand, but in the actual application, according to the heat treatment furnace, furnace temperature, combustion medium, temperature rise requirement of ceramic fiber module density in 200-240Kg/m fand, ceramic fiber blanket, because the processing of ceramic fiber module uses double roller today advanced technology and technology of silk, fiber length of the ceramic fiber blanket which produced in 80-130 mm, so the maximum density of the ceramic fiber module is more than the density, 240Kg/m fand, a large amount of fiber fracture, the fracture rate is as high as 48%. So after the actual verification at home and abroad of tens of thousands of industrial furnaces, the best density of ceramic fiber module is fand 220Kg/m.

Q: Should the ceramic fiber furnace be compacted?: The simplest, the least durable method, uses ceramic fiber blankets for wrapping, which is often caused by the poor density of the ceramic fiber blanket and the lack of anchorage

Q: What is the difference between the ceramic fiber cloth and the high silicon oxygen cloth?: High temperature is similar to that of strength, service life, the price is high silica cloth. High silica fabric belongs to glass fiber.

Q: Is the ceramic fiber cloth poisonous?: Aluminum silicate fiber textiles can replace asbestos textiles, widely used in metallurgy, chemical industry, ceramics. Glass, refractories, shipbuilding, aerospace, automotive, machinery, electronics, building materials, light industry and other industrial sectors of the fire-resistant, heat insulation, fire prevention, friction, sealing, silencing, labor protection, high temperature filtering etc..Landlord, it seems that this material is non-toxic, rest assured that the use of good.

Q: What is the diameter of the ceramic fiber? How to mix?: Fiber length: fiber rejection is longer, the rejection of silk fiber is generally 150-250mm, spinneret fiber is generally 100-200mm;

Q: Is aluminum silicate fiber poisonous?: Then use the compressed air jet or use the wire throwing machine to turn the yarn into a fiber. After the cotton collector sets the cotton, it forms the ceramic fiber cotton. In the whole process of production, it can be found that the raw material does not contain toxic substances. Compared with asbestos, it is a substitute product of asbestos and contains no carcinogens.

Q: What is the good heat insulation effect of glass fiber and aluminum silicate fiber, what are their respective advantages and disadvantages?: Adiabatic effect: glass fiber thermal conductivity at room temperature was about 0.056, the thermal conductivity at room temperature is about 0.035, due to the lower thermal conductivity, moisturizing effect is better, so the material characteristics of aluminum silicate fiber insulation effect is good, but also with the insulation effect of fiber compression density, can not be generalized.

Q: The difference between the ceramic fiber blanket and rock cotton blanket: Refractory ceramic fiber material is a lightweight and efficient thermal insulation material. It has the following advantages over traditional heat insulation materials:Ceramic fiber as lining, low volume density: ceramic fiber lining than light heat insulation brick lining light more than 75%, lighter than light castable lining light 90% to 95%. If using fiber lining, it can greatly reduce the steel structure load and prolong the service life of the furnace.

Q: Aluminum silicate needle carpet and ceramic fiber insulation performance of the good: Aluminum silicate needle carpet should be aluminum silicate needled blanket, with the continuous production, by acupuncture fiber uniformity, high tensile strength, does not contain any additives. Ceramic fiber, also known as aluminum silicate fiber, is only a different name.

Q: Ceramic fiber material fire shutter door how many square?: If the above two kinds of roller blinds, really true to do, the former per square meter at least 500 yuan, and the latter at least 400 yuan per square meter. Otherwise, there must be a problem.
