Problems solved by technology

[0004] The existing glass fiber coated substrate is made of ordinary glass fiber, and the diameter of the single filament is generally 7-11 μm. Due to the slightly poor folding resistance of glass fiber, its application industry is limited to a certain extent.
At the same time, due to factors such as production technology and post-processing technology, the performance indicators of glass fiber coated substrate products such as folding resistance, corrosion resistance, water and oil repellency, and the combination of substrate and film cannot fully meet the requirements of use.

Embodiment 1

[0027] The high-performance ultra-fine glass fiber expanded film-coated base material and the preparation method thereof of the present invention comprise the following steps:

[0028] 1. After the high-quality raw materials are washed, they are put into a kiln at 1350°C, melted at a high temperature, and passed through a yarn making system to make ultra-fine glass fiber yarn with a single filament diameter of 3.8-5.5 μm. The warp yarn and weft yarn are spun into warp yarn and weft yarn respectively after debonding and twisting. The warp yarn is warped to make a warp beam, and the weft yarn is woven into a 750g / ㎡ glass fiber cloth after being bulked and deformed.

[0029] 2. Heat-clean the woven glass fiber filter cloth of 750g / ㎡, and remove various additives on the surface of the fabric through high temperature, so as to facilitate subsequent processing; the temperature of the heat-cleaning process is 200°C-450°C, and the running speed is 6m / min.

[0030] 3. The cleaned fil...

Abstract

The invention provides an ultra-fine glass fiber coated substrate and a preparation method thereof. The preparation method comprises the following steps of: cleaning a glass fiber raw material after being inspected, and carrying out high-temperature melting and fiber drawing to obtain an ultra-fine glass fiber yarn; allowing the ultra-fine glass fiber yarn to be subjected to unwinding, doubling and twisting, bulk treating, warping, weaving and other processes to obtain ultra-fine glass fiber bulked cloth; allowing the ultra-fine glass fiber bulked cloth to be subjected to thermal cleaning treatment and impregnation treatment; and finally, allowing the material to be sequentially subjected to volatilization, drying, sintering and hot rolling setting treatment. The ultra-fine glass fiber coated substrate obtained by the method has the advantages that the temperature resistance, corrosion resistance, filter effects and the like are significantly improved, the production cost is lower, the service life is long, the requirements of the coating process can be fully met, and the ultra-fine glass fiber coated substrate is novel filter material with excellent price-performance ratio.

Description

technical field [0001] The invention relates to the field of environmental protection dust-removing filter materials, and provides a film-coating base material and a preparation method thereof, in particular a film-coating base material made of ultrafine glass fibers. Background technique [0002] Due to its advantages of wide application conditions and high filtration precision, the bag filter is widely used. As the core of the bag filter, the filter material is developed from deep filter to surface filter. [0003] At present, high-temperature flue gas filter materials mainly include high-temperature resistant needle-punched filter material and high-temperature-resistant film-coated filter material. High-temperature-resistant film-coated filter material has become the main development because of its higher filtration efficiency than high-temperature resistant needle-punched filter material. High temperature resistant filter material. The glass fiber / PTFE high-temperature ...
