Q: What are the main differences between an ordinary furnace and a ceramic fiber furnace?: Service life: ordinary furnace quenching, sudden heat, easy to cause blasting chamber or cracking, shorten service life, ceramic fiber furnace without blasting chamber or crack possible.There are two common practices in ceramic fiber furnaces:The first is a larger furnace, which is fixed on the furnace wall with ceramic fiber modules;The second is a small furnace, the manufacture of abrasives, direct pouring, or with punch milling machine processing ceramic fiber board.

Q: What is the density of ceramic fiber modules? The best insulation effect: Ceramic fiber module density in 200-220, the first production of ceramic fiber module is generally made of ceramic fiber blown blanket, fiber blown blanket fine short, ceramic fiber module is made out of the expansion is relatively stable, but in recent years because of the cost of production, the majority of ceramic fiber module are thrown silk do relatively, the tensile force is big, according to your own combustion atmosphere of furnace temperature and heating module and intracranial, select the density and thickness of the ceramic fiber module. Just make the insulation layer, then recommend 200kg/ cubic meters. Ring fire-resistant insulation materials company has a specific index and design analysis.

Q: What is the difference between the ceramic fiber cloth and the high silicon oxygen cloth?: 1. Ceramic fibers are short fibers that need to be strengthened and toughened by other objects. They are generally toughened by glass fiber and stainless steel wire.2 and high silicon oxygen is long fiber, no need to toughen by other objects.3 short, high silicon oxygen resistance to high temperature, Suzhou Dexin ceramic high silica cloth of silica content is greater than or equal to 96% temperature up to 1700 DEG C.

Q: Glass fiber cotton, aluminum silicate cotton, rock wool, what's the difference between these three?: Rock wool: is a kind of insulation materials, widely used in exterior wall insulation, because rock wool dust carcinogenicity, the state has banned the use of industry.

Q: Aluminum silicate ceramic fiber cotton smoke will cause pneumoconiosis?: 1, general masks, gauze, masks, etc., can not be used as dust masks.2, mask must pass GB 2626-2006 standard certification.3, it is recommended to choose N100 class dust masks.4, individual suggestions according to choose different shapes masks.5, it is recommended to change the filter gauze mask. Material recommended for silicone material.Through the above way, it can effectively prevent pneumoconiosis.

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?: The diameter of the general ceramic mineral fiber is 2---5 microns, and the length is in the range of 0---8 mm long.Ordinary mixing machine can be easily mixed, and the mixture of other good affinity, evenly dispersed and mixed resin or rubber and liquid glue, thus make the fiber products look pretty smooth, bright color, anti impact friction resistance, small abrasion, tensile Xinghao, can effectively reduce the noise without damage dual, can reduce the amount of metal fiber.

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.
