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?
Three kinds of materials are heat insulation materials, applications and temperature resistance is different.Glass fiber cotton is a kind of excellent performance of inorganic non-metallic materials, variety, has the advantages of good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, but the disadvantage is brittle, poor wear resistance, the maximum temperature of four less than Baidu.
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: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: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: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:Is aluminum silicate fiber poisonous?
Hello, silicate in the stomach and stomach acid reaction, forming insoluble silicic acid. There should be no toxicity.
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?
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.
