Problems solved by technology
However, the disadvantage of this traditional method is that the measurement method is complex and cumbersome, and requires standard sample preparation, and the product cannot be directly measured, and the measured heat distortion temperature is much higher than the lowest deformation temperature of the plastic itself, so the Vicat softening point is used There are many limitations to using a tester to measure the heat distortion temperature of plastic edge banding strips

Embodiment Construction
[0021] In this example, refer to figure 1 , the method for measuring the heat distortion temperature of the furniture thermoplastic edge banding, including a test process and a comparative test;
[0022] A. The test process is carried out in the following steps:
[0023] 1), prepare the circulating air oven 1, test bench, timer (not shown), wherein the test bench is composed of a support frame 2, a sample support table 3 and a scale 5, and the sample support table 3 and the scale bar 5 are fixed on the support frame 2 together to form the entire test bench;
[0024] 2), prepare 5 edge banding samples 4, of course, it can also be 3 or 4, and the length is 160-170mm;
[0025] 3), according to different samples, set the circulating air oven to the corresponding initial temperature, and put it into the test stand; the sample support platform 3 is placed on the support frame 2, and the sample support platform 3 includes two support units, two The distance between the support uni...

Abstract
The invention discloses a heat distortion temperature measuring method for thermoplastic sealing stripes for furniture, comprising the following steps of: preparing a circular wind oven, a test board, a timer and samples; setting right temperature for the circular wind oven and putting the circular wind oven into the test board; after the temperature is stabilized to a set value, putting one sample, and observing for ten minutes in the terms of a graduated scale; if the sample has no distortion after ten minutes, raising the temperature, and observing for ten minutes again; if the sample has no distortion, raising the temperature again, and observing again; raising the temperature of 5 DEG and observing for ten minutes each time, till the sample starts distorting, and the temperature at the moment is the heat distortion temperature of the sample; and averaging values of all samples. The measuring method adopts the circular wind oven, the test board, the graduated scale and the like and controls the temperature by the circular wind oven so as to be used for directly measuring the heat distortion temperature of plastic sealing stripe products, and therefore the measuring method is simple and visual. The measured result self comes from the actual products, and thus the measured result is accurate. In addition, as the whole measuring method is simple, the testing cost and the testing time are greatly saved.
Description
technical field [0001] The invention relates to the technical field of thermal deformation detection of products, in particular to a method for measuring the thermal deformation temperature of thermoplastic edge banding strips for furniture. Background technique [0002] Furniture edge banding is a material for protecting, decorating and beautifying the outline of furniture panels. Its main function is to seal the section of the panel so as to prevent the panel from being damaged by the environment and unfavorable factors (mainly moisture) during use. And prevent the volatilization of formaldehyde inside the board, and at the same time achieve the effect of decoration, its material is mostly made of PVC and other plastics. Heat distortion temperature is one of the important indicators to measure the heat resistance of plastic edge banding, and it is also one of the important standards to measure the quality of plastic edge banding. In the traditional technology, the Vicat s...
