Abstract

The invention discloses an improvement method for electronic grade glass fiber yarn preparation. According to the method, an existing three-point G75-1200H bushing plate is improved into a four-pointG75-1200H bushing plate, one partition is increased, a beam splitting mode is adjusted into 4R-1*4 from 4R-1*3, an existing six-point E225-1200 bushing plate / D450-1200H bushing plate is improved intoan eight-point E225-1600H bushing plate / D450-1600H bushing plate, two partitions are increased, a beam splitting mode is adjusted into 2R-1*8 from 2R-1*6, an eight-point D900-800H bushing plate is improved into a ten-point D900-1000H bushing plate, and two partitions are increased. According to the method, molten glass flow can be improved within unit time, production efficiency is improved, the rotating speed of a wire drawing machine is improved, wire drawing and winding time is reduced, production energy consumption is saved, wire arrangement ratio is adjusted, wire cake forming is improved, the width of a wire cake is reduced, so that the total width of the wire cake is matched with a wire drawing machine head, an oil sprayer is improved, oil spraying rotating speed is adjusted, and quality exception such as abnormal oil content caused by poor oil spraying effect is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic fiber cloth processing, in particular to an improved method for preparing electronic grade glass fiber yarn. Background technique [0002] The existing electronic-grade glass fiber yarn products are prepared by 3-split and 6-split processes according to the diameter of the monofilament and the linear density of the yarn. ×6 etc. The glass liquid is adjusted to a suitable temperature through the leak plate, then flows out through the leak nozzle, and is stretched into continuous glass fibers by the wire drawing machine at the outlet; [0003] The main problems and shortcomings in the existing electronic fiber cloth preparation process are as follows: [0004] 1. There are few partitions of the existing leakage board, and the beam splitting methods are 4R-1×3, 2R-1×6, etc., the production efficiency per unit time is low, the unit production cost is high, and the market competitiveness is insuff...
