If the sintering felt is used, if the temperature is relatively high, the filament diameter may have some influence on the use of the product, so what are the effects? How to know it? Today TopTiTech will introduce for you below.
First of all, in the use of sintering felt products, the thinner the filament diameter, the larger the surface area, at the same time, the atomic surface will be lower, and the diffusion distance of the atoms will become smaller, when the situation is serious, it may affect the sintering speed of the product.
Secondly, in the process of using sintering felt products, the fiber filament diameter is relatively special because of its processing mode, so it may store more deformation capacity. Therefore, when the temperature becomes high, the sintering product may appear crystal boundary diffusion and body diffusion, which will cause the contraction of the product.
In addition, because the sintering felt product is a filter product, the hole structure between the fibers cannot be consistent before the sintering production work, but after the sintering work, it will have a greater strength.
The above is the impact of fiber filament diameter on sintering felt products. I hope you can pay more attention to the above content when using this product in the future.
Metal fiber sintering felt production process manufacturing
Performance of
● metal fiber filter felt: the high porosity of 85% can ensure that the filter material passes through the
large flow rate, long enough online life and very low pressure drop, thus smaller
than the filter area of other filter materials.The porous structure of the
● sintered metal fiber filter felt allows the user to perform online backblowing or backwash on the
machine.
● thin film type filter material is easy to break wave and welding. During the sintering process, the crosslink of the fiber is fused together so that the filter material has high strength, coupled with a large enough internal space, the filter material can withstand heat impact, high pressure and frequent reverse pulse cleaning.
● metal fiber filter material of different alloy materials can be used for high temperature, even up to
1000℃ of high corrosion conditions, other materials such as non-metallic fabrics such as chemical
fiber or ceramics can not be compared. The gradient-type hole structure of the
● filter material can achieve higher efficiency. For a deep filtration, the forward installation has a high
enough contamination capacity, and as a surface filtration, the reverse installation forms a filter cake
that can be backwashed online.
● non-embroidered steel and other alloys have the characteristics of low thermal expansion, no brittle,
easy welding and no deformation under thermal shock. Choose suitable alloy can meet
therequirements of strength and harsh working conditions.
● When applying depth filtering, it is recommended to choose a multi-layer structure to increase the
contamination capacity.
● sintered metal fiber filter felt produces many shapes and series: candle core filter element (broken
wave or not broken wave), disc filter plate. When high-pressure fine melt filtration is needed, the filter
plate processed with sintering metal fiber filter material with double-sided professional title net is
better to replace the filter element.
