Problems solved by technology

[0003] The corrosion of glass fiber by water is much slower than that of acid and alkali. The normal temperature test takes a long time. In addition, the exchange of cations in glass fiber with hydrogen ions in water will easily lead to changes in the water environment. A single boiling test cannot accurately reflect its water resistance. Good or bad, the present invention provides a high accuracy, simple operation, and can be used for measuring device and method for water resistance of glass fiber

Abstract

The invention discloses a measuring device and a measuring method of glass fiber water resistance. The measuring device of the glass fiber water resistance comprises a first peristaltic pump, a first water conveying pipe, a first heater, a first container, a second water conveying pipe, a second peristaltic pump, a third water conveying pipe, a second heater, a second container, a fourth water conveying pipe and a third peristaltic pump. The method for measuring the glass fiber water resistance is characterized in that a glass fiber test sample is put into boiling water; through controlling the sample quantity, the boiling water volume and the boiling water displacement rate, the alkaline corrosion influence is eliminated; the effect of water on the glass fiber is enabled to be always hydrolysis reaction; finally, the glass fiber water resistance is evaluated through measuring the mass loss rate or the monofilament tensile fracture strength retention rate. The measuring method has the advantages of short test time, operation simplicity, good repeatability and the like.

Description

technical field [0001] The invention relates to a measuring device and a measuring method for the water resistance of glass fibers, belonging to the detection field. Background technique [0002] The use environment of glass fiber is unavoidable water or water vapor, so the water resistance of glass fiber is an important factor to be considered. Reasonable evaluation of glass fiber changes in water environment will help guide the use and development of glass fiber products. For the determination of glass fiber water resistance, there is no report yet. Commonly used glass or glass bottles, such as flat glass and infusion bottles, are tested for their water resistance according to GB / T6584-1997 "Particle Test Method and Classification of Water Resistance of Glass at 98°C", and the treatment method is to fix a certain sample in a quantitative manner. In constant water, heat for a certain period of time to test the amount of alkali analysis. However, this method is not suitab...
