Example Embodiment

[0051] Example 1

[0052] This embodiment provides an electronic grade glass fiber cloth, a technical means of using liquid carbon dioxide pre-cream and hydraulic fiber, and the specific preparation method is as follows:

[0053] Step S0: Install the 1080 glass fiber cloth to the machine to send the start button, and the glass fiber cloth begins to transfer forward;

[0054] Step S1: Glass fiber cloth enters liquid Co 2 Pre-open fiber area, open liquid CO 2 Spray pump switch, liquid CO 2 By uniformly distributed between the glass fiber cloth, the liquid carbon dioxide spray rod 1 is uniform, and the gasification expansion is started, the suction pipe 5 also starts working, and the volatile CO is extracted. 2 The gas will be re-become liquid CO through the compression equipment. 2 And store, then the fiberglass cloth along the first guide Brula 3 and the second guide Bride 4 through the constant temperature water bath 2, so that liquid CO 2 Volatilize and thoroughly, draw the volatil...

Abstract

The invention discloses a glass yarn splitting method for electronic-grade glass fiber cloth and a product thereof. The splitting method comprises the following steps of S1, uniformly spraying liquid carbon dioxide on the glass fiber cloth, and obtaining pre-split glass fiber cloth through a constant-temperature water bath; and S2, carrying out spunlace splitting treatment on the pre-split glass fiber cloth to obtain the split glass fiber cloth. According to the splitting method for the electronic-grade glass fiber cloth provided by the invention, liquid carbon dioxide pre-splitting is applied before a spunlace splitting method, so that the surface of the glass fiber cloth is uniform and flat, and the thickness is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of electronic grade non-alkali glass fiber cloth, in particular to a fiber opening method for electronic grade glass fiber cloth and its products. Background technique [0002] With the advent of the 5G era, the electronics industry is developing very rapidly, and electronic product terminals are becoming smaller and thinner. Therefore, the PCB circuit boards used in the production of electronic products must also be thinner and better, and the production of PCB circuit boards is the most The original electronic material is electronic-grade glass fiber cloth, so the glass fiber cloth should be made lighter and thinner, with a smoother appearance. [0003] In the existing production process of electronic grade glass fiber cloth, the original cylindrical glass yarn is hit and dispersed into a flat ribbon structure by the high-pressure water jet ejected from the jet plate, thereby reducing the thickness of the ...
