This standard was proposed by the China Building Materials Federation. This standard is under the jurisdiction of the National Glass Fiber Standardization Technical Committee (SAC/TC245). This standard was drafted. Jushi Group Co., Ltd. The main drafters of this standard. Cao Guorong, Ye Fenglin, Wang Haixing, Cui Fengbo, Zhao Gang, Du Jiakui, He Qiuyan. Determination of the electrostatic properties of glass fiber roving1 ScopeThis standard specifies two methods for determining the electrostatic properties of glass fiber roving. ---Method A. Electrostatic adsorption method; --- Method B. Static voltage half-life method. This standard applies to glass fiber roving.2 Normative referencesThe following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 6060.3 Surface roughness comparison specimens Part 3. EDM, throwing (spraying) pellets, sand blasting, grinding, boring, polishing surface.3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 Electrostatic adsorption mass electrostaticadsorptionmass The quality of the residual roving that is attracted to the stainless steel plate due to frictional static electricity. Note. in grams (g). 3.2 Static voltage half-life statichalfperiod The time required for the static voltage on the sample to decay to half the initial value. Note. in seconds (s).4 Principle4.1 Electrostatic adsorption method The sample is introduced into the chopper for cutting, and the cut yarn segment is freely dropped onto a special inclined surface, and the friction is generated during the cutting process. Static electricity causes the yarn segments to adhere to this slope, and the adsorbed yarn segments are collected for weighing to determine the electrostatic properties of the sample. Adsorbed yarn segment The lower the quality, the stronger the ability to represent antistatic, and the weaker the antistatic ability. 4.2 Static voltage half-life method Applying a certain electrostatic voltage to the sample, and measuring the time required for the electrostatic voltage to decay to half of the initial value by ground discharge, Thus, the electrostatic properties of the sample were measured. The shorter the time, the stronger the antistatic ability, and the weaker the antistatic ability. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 36494-2018_English be delivered?Answer: Upon your order, we will start to translate GB/T 36494-2018_English as soon as possible, and keep you informed of the progress.
