Embodiment Construction

[0026] In order to describe the technical content, structural features, objectives and effects of the present invention in detail, it will be described in detail below in conjunction with the implementation and accompanying drawings.

[0027] see figure 1 with figure 2 , which is a 2 / 2 twill weave texture front and back electron microscope enlarged view of the filter cloth fabric used in the pharmaceutical industry for high-purity extraction of the present invention.

[0028] The present invention mainly aims at the interception of ultra-fine powdered barium sulfate below 0.3 microns, and maximizes the water permeability of the filter cloth under the premise of meeting the interception accuracy; at the same time, good cake removal performance helps enterprises reduce a large amount of waste in actual production. Labor costs.

[0029] It is applied to the filter cloth of nano-barium sulfate. The multifilament of the filter cloth is made of ultra-fine denier porous polypropyl...

Abstract

The invention discloses a filter cloth applied to nano-barium sulfate. The multifilament of the filter cloth adopts ultra-fine denier porous polypropylene multifilament. After the filter cloth is woven from warp and weft threads, it is subjected to a high-temperature instantaneous polymerization surface treatment process through a calender. The texture of the filter cloth is plain weave, twill weave, satin weave or any of all multi-layer fabric structures, and the high temperature range is 120~220°C. The filter cloth has the advantages of high retention precision, good filter cake peelability, excellent acid and alkali resistance, good hydrophobicity, and good regeneration. The invention also discloses the weaving method of the filter cloth.

Description

technical field [0001] The invention relates to a filter cloth applied to nano barium sulfate and a weaving method thereof. Background technique [0002] With the development and utilization of new functional devices and the vigorous development of the material industry, barium sulfate, as an important raw material in many industries, its application fields are expanding day by day, and its quality requirements have been significantly improved. In recent years, many countries have actively carried out the improvement of traditional synthesis processes, especially seeking new breakthroughs in improving product structure and quality, reducing energy consumption, and simplifying processes. And the development and application research of special barium salt varieties, pay more attention to the introduction of new ultrafine powder varieties with high purity nanometer and special value in terms of particle size and related specifications, so that barium salt products occupy a very...
