Abstract
The invention relates to glass fiber filtration cloth for flue gas dust removal, which comprises a base fabric and a coating, and is characterized in that: a, the base fabric is low-wax filtration cloth; and b, the coating comprises the following raw material components in percentage by weight: polyfluortetraethylene emulsion ( with a solid content of 50 percent) 18-25, silicon oil emulsion (with a solid content of 55 percent)4-7, graphite powder (with a particle diameter of less than or equal to 0.1mum) 1-5 and water 68-70. The invention successfully solves the problems of low product quality, short product service life and high production cost which result from high dewaxing temperature, low rotating speed of a discharge roll and uneven coating in the prior art by providing the glass fiber filtration cloth for flue gas dust removal which has the advantages of low dewaxing temperature, low power consumption, high production efficiency, even coating, high anticorrosion performance and long service life. The dewaxing temperature drops by more than 60 DEG C and the rotating speed of the discharge roll is increased by more than 400 r/min.
Description
Technical field
The present invention is a kind of glass fiber filtration cloth for flue gas dust removal.Belong to the filtering material production and processing that is used for gaseous fluid.
Background technology
For the atmospheric environment of protecting the mankind to depend on for existence, the flue gas that industry such as iron and steel, thermoelectricity, coking, pottery, cement produces must discharge after udst separation.Therefore, the demand of flue-gas dust removal and purification with glass filter cloth increased year by year, and product quality and product price are constantly proposed harsh more requirement.Obviously, improve the quality of products, reducing production costs is the eternal pursuit of manufacturer of flue gas ash removal with filter cloth.
In the prior art, be base cloth with commercially available content of wax glass filter cloth, the wax content height.Have to dewax under temperature higher more than 360 ℃, the discharge roller rotating speed can only be controlled at below 800 rev/mins.The dewaxing temperature height, base cloth intensity is impaired and power consumption is high; The discharge roller rotating speed is low, and production efficiency is difficult to improve: and dewaxing is still complete inadequately, causes that coating is inhomogeneous, coating weight is few, influences the decay resistance of filter cloth.Shorten the service life of filter cloth, increased user's use cost.
Summary of the invention
The objective of the invention is to avoid above-mentioned weak point of the prior art, and provide a kind of base cloth dewaxing temperature low, power consumption is low, production efficiency is high.Coating is even, corrosion resistance and good, the flue-gas dust removal and purification glass fiber filter cloth of long service life.
Purpose of the present invention can reach by following measure:
Glass fiber filtration cloth for flue gas dust removal of the present invention comprises base cloth and coating, it is characterized in that:
A. base cloth: adopt low wax filter cloth; Wax content is controlled within the 0.5-0.8wt%.
