Specifications

Ceramic wool paper 
Density: 200-250kg/m3 
Thickness: 1~6mm 
Temperature:1260C 
Customized service is also available.

ceramic wool paper is a lightweight refractory material processed from a blend of high purity alumina-silica fibres into a highly flexible, uniform sheet. It is recommended for classfication temperatures up to 1260C. Ceramic fiber paper has low shirngkage, good handling strength, and low thermal conductivity. It contains a small amount of orgainc binder for processing which makes it flexible, and reduces off-gassing and odour during use. Our product has a highly uniform structure due to its controlled basis weight and thickness, assuring homogeneous thermal conductivity and a clean, smooth surface ideas for gasket or sealing. Ceramic fiber paper is completely free of asbestos, and is designed to be an economic replacement for asbestos paper in most applications. Ceramic fibre paper is easy to cut with a knife, shears, or standard steel rule dies. Its flexibility allows it to be wrapped or rolled to fit most complex configurations.

 Application

Q:How many insulation supporting pins are there in one aquare meter of glass wool?
From my experience, the interval of 300 is possible. The design value of uplift is determined by the parts of insulation. And the exterior wall, self-weight, etc. is caculated based on the uplift test of the stud. It asks for strict methof or air duct, involving wind load; And it is also based on the load.
Q:Why does glass wool turn black when exposed to heat? Wether it will ffect the thermal insulation effect.
The burning like alcohol lamp uses glass wool as the substrate. There are two possibilities to take alcohol lamp to do experiment, which containing organic substances. 2. 1, High temperature oxidation. I produce aerogel thermal insulation felt, and I have seen that the charcoal ash produced is attached to the glass wool. It has some impact on thermal insulation effect, but the impact is small.
Q:Does glass wool equals to rock wool?
It mainly used in the thermal insulation of air-conditioning ducts, has coarse fibers. Isover has pink glass wool roll mats. Black soft cotton is rubber and plastic. Rock wool is generally dark and the glass wool is golden.
Q:How to distinguish green glass wools?
Rock wool is much harder than glass silk. rock wool color: Khaki, deep. glass silk wool color: yellow, light. Cellosilk is not the same. Rock wool is harder while glass silk wool is softer. Rock wool is white, without elasticity. It is irritating to skin. But glass wool is yellow, with elasticity and without irritation to skin. Glass wool is made through high temperature melting of industrial waste glass, and then making glass into flow by high-speed centrifuge, pulling glass flow into fiber under high temperature and high speed. Rock wool is inorganic fiber made by base materials of fine basalt after high temperature melting in high-speed centrifugation equipment. Glass wool is more economical and environmentally friendly than rock wool.
Q:Who can tell me about the unit weight of glass wool board?
Glass wool has a good sound absorption performance in the high-frequency sound. The main factors affecting the centrifugal glass wool' sound absorption performance are thickness, density and air flow resistance, etc. Density is the weight per cubic meter of materials. 1. with the increase of thickness, the low frequency sound absorption coefficient significantly increases, but there is little change in the high frequency (high frequency absorption is always larger). 2. thickness is the same, the unit weight increases, the low frequency sound absorption coefficient also increases; but when the unit weight increases to a certain extent, the material becomes dense, the flow resistance is greater than the optimum flow resistance, sound absorption coefficient decreases.
Q:Is centrifugal glass wool or rubber and plastic insualtion board better for air-conditioning air duct insualtion?
Rubber and plastic insulation board is better.
Q:What are the applications of centrifugal glass wool board?
Centrifugal glass wool board is board product with a certain intensity which is made by curing centrifugal glass wool. Whether in high or low temperature environment, it can maintain good heat insulation and sound absorption properties, mainly used for interior wall compartment in advanced architecture, compartment, ceiling, heat conservation for iron sheet air duct or aie bellow, sound absorption and noise reduction for studio, machine room and other places.
Q:How much does centrifugal pan of glass wool need to invest? ?
Plus plant and recipe, it is almost 40 million, and the raw material is about 3,000.
Q:Glass wool 159 * 70 What does it mean
Glass wool pipe specifications 159 refers to pipe diameter of 70 mm.
Q:What is the density of high-temperature glass wool ?
Sound absorption characteristics of glass wool depends on its thickness and density as well as overlay of pavement materials and structure. When applied to practical situations, we should also take into consideration of the cost, appearance, fireproof property, moistureproof, dust, anti-aging.
