Embodiment 1

[0059] Test sample: E-glass fiber direct roving, 300tex.

[0060] Test conditions: the test temperature is 20-26°C, and the test humidity is 55-75%.

[0061] Test steps:

[0062] (1) Prepare glue: select acrylate emulsion, add water to dilute to a solid content of 24% and stir evenly, then pour it into the glue coating tank 21;

[0063] (2) Prepare the spline: the yarn of the yarn cluster of the sample to be tested passes through the tensioning assembly 1, the gluing assembly 2 and the squeegee assembly 3 successively, and finally winds on the spline mold 41 of the mold assembly 4, and the winding speed is controlled At about 500mm / min, so that the acrylate emulsion can fully infiltrate the glass fiber yarn, and prepare 20 splines by winding at one time;

[0064] (3) Spline drying: put the spline mold 41 wound with the yarn into an oven and bake at a temperature of 190° C. for 15 minutes to dry the moisture on the yarn, so that the acrylate on the surface of the yarn is cons...

Embodiment 2

[0080] Test sample: medium alkali glass fiber direct roving, 300tex.

[0081] Test conditions: temperature at 20-26°C, humidity at 55-75%.

[0082] Test steps:

[0083] (1) Prepare glue: select acrylate emulsion, add water to dilute to a solid content of 24% and stir evenly, then pour it into the glue coating tank 21;

[0084] (2) Prepare the spline: the yarn of the yarn cluster of the sample to be tested passes through the tensioning assembly 1, the gluing assembly 2 and the squeegee assembly 3 successively, and finally winds on the spline mold 41 of the mold assembly 4, and the winding speed is controlled At about 500mm / min, so that the acrylate emulsion can fully infiltrate the glass fiber yarn, and prepare 20 splines by winding at one time;

[0085] (3) Spline drying: put the spline mold 41 wound with the yarn into an oven and bake at a temperature of 190° C. for 15 minutes to dry the moisture on the yarn, so that the acrylate on the surface of the yarn is consolidated Fo...

Abstract

The invention provides a sample preparation device and a performance testing method. The sample preparation device is used for preparing a line body into a sample strip. Along the moving direction of the line body, the sample preparation device comprises a tensioning assembly which is used for tensioning the line body before gluing, a gluing assembly which is used for coating the line body with glue, a glue scraping assembly which is used for removing redundant glue on the line body, and a mold assembly which comprises a sample strip mold movably arranged, so that the line body is wound on the sample strip mold circle by circle to form a sample strip. The sample preparation device provided by the invention solves the problems of long testing period and low testing efficiency of glass fibers in the prior art.

Description

technical field [0001] The invention relates to the technical field of glass fiber performance testing, in particular to a sample preparation device and a performance testing method. Background technique [0002] In the prior art, the alkali-resistant glass fiber mesh cloth is usually made of medium-alkali and non-alkali glass fibers twisted through leno tissue, and then subjected to high-temperature heat-setting treatment such as alkali-resistant liquid and reinforcing agent to have good anti-alkali. Alkaline, flexible and highly resistant to warp and weft, it is an ideal engineering material for the construction industry. [0003] Alkali-resistant glass fiber mesh cloth is generally used in building walls. Since the wall contains alkaline materials such as cement and mortar, these alkaline materials will corrode the mesh cloth, thereby greatly reducing its alkali resistance. How to use glass fiber mesh Measuring the alkali resistance of grid cloth is extremely important f...
