Problems solved by technology

[0003] The traditional yarn abrasion tester can only automatically record the number of reciprocating movements of the grinding roller when the yarn breaks through the counter, and can only judge one-sidedly through the time required for the yarn to break, and cannot observe the shape of the yarn Therefore, it is impossible to make targeted improvements to the yarn. Based on this, the present invention discloses an electronic-grade glass fiber abrasion resistance testing device and testing method, which can simultaneously evaluate the wear resistance life of the yarn and the shape of the yarn during the friction process.

Embodiment 2

[0065] A method for testing the abrasion resistance of electronic grade glass fibers of the present invention comprises the following steps:

[0066] Step 1: Load and unload the grinding roller, turn the screw to remove the grinding roller cylinder, place the opening of the grinding roller cylinder on the top, then open the fixing buckles at both ends, fix the abrasive on the grinding roller cylinder, close the cylinder cylinder, the grinding roller cylinder is fixed on the connecting rod 5;

[0067] Step 2: Prepare the sample, sample the yarn, pass the sampled yarn through the limit yarn guide rod, yarn guide rod, grinding roller, and limit groove, and fix one end of the yarn in the working position When the yarn is fixed, the screw of the yarn fixing device is loosened first, the yarn is wound on the cylinder, and the screw is tightened to make the gasket press and fix the yarn. Connect the other end of the yarn to the tension control device, then cut the yarn, and apply te...

example 1

[0085] Example 1: The grinding roller uses 7628 glass fiber cloth (produced in-house). After the grinding roller reciprocates 2463 times, sample 1 breaks, the tension suddenly becomes 0, it takes 41 minutes, and the average number of hairiness is 28 when it breaks.

Abstract

The invention discloses an electronic-grade glass fiber wear resistance testing device and method, and belongs to the technical field of glass fiber testing devices.The electronic-grade glass fiber wear resistance testing device comprises glass fiber yarn, a yarn fixing device, a yarn grinding roller and a yarn guide rod; the glass fiber yarn is connected with a tension control device after passing through the yarn fixing device, the yarn guide rod and the yarn grinding roller; the exterior of the yarn grinding roller is connected with a motor; a high-speed camera is arranged above the yarn grinding roller; connecting rods are arranged on the left side and the right side of the yarn grinding roller and connected with the yarn guide rod and the high-speed camera; the motor is connected with a controller, the controller is connected with an infrared sensor and a counter; and the motor drives the yarn grinding roller to reciprocate and records mutation of yarn hairiness before and after friction; and the controller records the number of friction times through the counter, and the controller is connected with a hairiness detection device. The wear resistance of the glass fiber yarn is detected and evaluated, and the problems in the prior art are solved.

Description

technical field [0001] The invention relates to an electronic-grade glass fiber wear resistance test device and a test method, belonging to the technical field of glass fiber test devices. Background technique [0002] Glass fiber woven yarn has been developed rapidly as a reinforcing material in recent years, especially in aerospace, electronics, machinery and other fields. The yarn will continue to wear, fuzz or even break during subsequent processing, which will affect the product quality and production efficiency of downstream customers. Therefore, evaluating the wear resistance of fibers has a considerable impact on the application of yarns and the development of more wear-resistant yarn structures. Significance. [0003] The traditional yarn abrasion tester can only automatically record the number of reciprocating movements of the grinding roller when the yarn breaks through the counter, and can only judge one-sidedly through the time required for the yarn to break, a...
