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:The difference between the ceramic fiber blanket and rock cotton blanket
The heat capacity (heat storage capacity) of ceramic fiber lining is low: the heat capacity of ceramic fiber is only about l/10 of light heat resistant lining and light castable lining, and the heat capacity of lining material is proportional to the weight of lining. Low heat capacity means the furnace in the reciprocating operation absorb less heat and heating speed, greatly reducing the operational control of the temperature in energy consumption, especially for heating furnace and furnace, furnace shutdown has obvious energy saving effect.
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:What is the difference between the ceramic fiber cloth and the high silicon oxygen cloth?
Ceramic fiber is a short fiber that needs to be reinforced and toughened by other objects. It is generally toughened by glass fiber and stainless steel wire. The high silicon oxygen is long fiber, no need to toughen by other objects. The short-time high silica 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:Ceramic fiber material fire shutter doors 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.
Q:Aluminum silicate needle carpet and ceramic fiber insulation performance of the good
Aluminosilicate ceramic fiber has two different production processes, respectively, the rejection process and the blowing process. The carpet produced by the spinning process has long fiber length, high tensile strength and wide range of use. The blanket produced by blowing process is short in length and easy to break, and the scope of application is relatively narrow.
Q:Aluminum silicate ceramic fiber cotton smoke will cause pneumoconiosis?
Because pneumoconiosis can not be cured by medical treatment, it brings great pains to the patients and the families. It is suggested that respiratory protection work be carried out.
Q:Is aluminum silicate fiber poisonous?
Ceramic fiber loose cotton is a kind of fluid which can melt high purity clay clinker, alumina powder, silica powder, chrome sand and so on in the industrial electric furnace.
Q:What are the main differences between an ordinary furnace and a ceramic fiber furnace?
The main difference between ordinary furnace and ceramic fiber furnace:Refractory, heat insulation: ceramic fiber furnace low thermal conductivity, low thermal conductivity, is a better thermal insulation materials, the use of temperature within one thousand and three hundred Baidu. The heat conductivity of common furnace is higher and the heat loss is great
Q:What is the good heat insulation effect of glass fiber and aluminum silicate fiber, what are their respective advantages and disadvantages?
Advantages and disadvantages of aluminum silicate fiber: high temperature insulation, heat preservation, fire resistance, noise reduction, insulation, light weight. Disadvantages: compressive resistance, bending force is relatively poor, easy to produce dust, waterproof performance is not very good.
