Embodiment 1

[0030] Such as Figure 1-3 As shown, a continuous glass fiber weather resistance test device according to the present invention includes a test box 1, and a yarn fixer 4 is arranged in the test box 1, and the yarn fixer 4 is used to fix the glass fiber yarn Inside the test box 1, the inside of the test box 1 is provided with a temperature control device, a light source control device, an acid-base control device and an air flow rate control device, and the outside of the test box 1 is provided with a controller and a display 9 to control The device is electrically connected to a display 9, a temperature control device, a light source control device, an acid-base control device and an air velocity control device.

[0031] There is also a non-friction yarn guide rod 8 inside the test box 1, and the friction-free yarn guide rod 8 includes a plurality to prevent the glass fiber yarns from turning over, shifting, sagging and interfering with each other.

[0032] The temperature co...

Embodiment 2

[0046]A kind of testing method of continuous glass fiber weather resistance testing device of the present invention, comprises the following steps:

[0047] Step 1: Put the glass fiber yarn at the leftmost end of the abrasion tester, draw the yarn along the tangential direction of the bobbin, and take a certain length of glass fiber yarn for sampling;

[0048] Step 2: pinch one end of the yarn by hand, pass the glass fiber yarn into the test box 1 through the frictionless yarn guide rod 8, and fix one end of the glass fiber yarn on the yarn fixing device 4;

[0049] Step 3: Tighten the glass fiber yarn at the left end, straighten the yarn, fix it with the yarn fixing device 4, and keep the glass fiber yarn level without sagging;

[0050] Step 4: Set the parameters of temperature, humidity, time, ultraviolet light source, air flow rate, acid concentration, and alkali concentration, and conduct aging and corrosion tests; set the corresponding running time, and the equipment will...

Abstract

The invention discloses a continuous glass fiber weather resistance testing device and method, and belongs to the technical field of glass fiber testing devices.The continuous glass fiber weather resistance testing device comprises a testing box, a yarn fixing device is arranged in the testing box, and the yarn fixing device is used for fixing glass fiber yarn in the testing box; a temperature control device, a light source control device, an acid-base property control device and an air velocity control device are arranged inside the test box, a controller and a display are arranged outside the test box, and the controller is electrically connected with the display, the temperature control device, the light source control device, the acid-base property control device and the air velocity control device. A plurality of aging corrosion parameters can be changed at the same time according to the use environment of glass fiber downstream products, and the application range is wide. And comprehensively evaluating the weather resistance of the glass fiber yarn by using the tensile breaking strength loss rate and the film forming state of the impregnating compound on the surface of the yarn. The method is accurate and time-saving; the problems in the prior art are solved.

Description

technical field [0001] The invention relates to a continuous glass fiber weather resistance test device and a test method, belonging to the technical field of glass fiber test devices. Background technique [0002] Fiberglass woven yarns are widely used as reinforcing materials in building materials, aerospace, electronics, machinery and other fields. The downstream products of glass fiber yarn are exposed to natural conditions and subjected to long-term corrosion by sunlight, wind, rain, water vapor and other gases, and will age, lose strength gradually, or undergo physical and chemical changes. In the prior art, there is a lack of devices for testing and evaluating the weather resistance of glass fiber yarns, which makes it impossible for technicians to test and evaluate the weather resistance of glass fiber yarns, and cannot meet the needs of customers; based on this, a continuous glass fiber Weather resistance testing devices and testing methods have become an urgent ne...
