The material and processing procedure of needle-punched non-woven fabrics are made of polyester and polypropylene raw materials, through carding, pre-carding, combing, pre-needling, and main needling. The center is added with a mesh cloth interlayer, and then through double nucleation, air-laid needles are combined into a cloth. The dust filter cloth has a three-dimensional structure. After heat setting and singeing, the surface is treated with a chemical oil agent to make the surface of the filter cloth smooth. , The micropores are evenly distributed, the product density is good from the surface, and the surface is smooth and air-permeable. The filter on the plate and frame compressor proves that high-pressure air can be used, and the filtering accuracy is up to 4 microns. Polypropylene can be provided according to user needs And polyester two kinds of raw materials.

Practice has proved that non-woven filter cloth has better performance in plate and frame filter press: for example, slime treatment in coal preparation plants, mineral extraction in beneficiaries, wastewater treatment in iron and steel plants, wastewater treatment in breweries, printing and dyeing plants. Other specifications of milk carbuncle will have the problem that the filter cake is not dry and difficult to fall off. After using the non-woven filter cloth, the filter cake will be quite dry when the filter press reaches 10kg-12kg, and the filter cake will automatically be automatically opened when the filter is opened. Fall off. When users choose non-woven fabrics, they mainly consider non-woven filter fabrics of different thickness and quality according to the air permeability, precision and elongation. The product parameters are introduced in the polyester needled felt and polypropylene needled felt. The specifications and varieties are all available. Formulate.

The needle-punched non-woven fabric series product room is formed by fine carding, multiple precision needle punching or proper hot-rolling treatment. Based on the introduction of multiple high-precision needle punching production lines at home and abroad, high-quality fibers are selected and passed through different production processes. With the combination of different materials, hundreds of different products are currently circulating on the market, including: geotextiles, geomembranes, needle felts, non-woven fabrics, MTS, flumes, acrylic, and coated needles Needle felt, anti-static needle felt, sandwich non-woven fabric.
