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
The present invention relates to the thermal deformation detection technique field of product, relate in particular to the heat distortion temperature assay method of a kind of furniture with thermoplastics edge sealing bar.
Background technology
The edge sealing of furniture bar is the material that the profile of Furniture panel is protected, decorates, beautified; Major function is that the sheet material section is carried out solid envelope; Reach the unfavorable factor (being mainly moisture) avoided in environment and the use destruction to sheet material; The formaldehyde inner with stoping sheet material volatilizees, and reaches the effect of decoration simultaneously, and its material adopts plastics such as PVC more.Heat distortion temperature is one of important indicator of weighing the plastic edge banding heat resistance, also is one of major criterion of weighing the plastic edge banding quality.In the conventional art, generally adopt the Vicat softening point analyzer for the mensuration of the heat distortion temperature of plastic edge banding, this method and supporting device are widely used in measuring plastic hot deformation temperature and softening temperature.Yet; The shortcoming of this classic method is; The assay method complicacy is loaded down with trivial details, and needs the standard sample preparation, can not directly measure product; And the heat distortion temperature deformation temperature of measuring minimum far above plastics itself, the heat distortion temperature that therefore adopts the Vicat softening point analyzer to measure plastic edge banding has many limitation.
Summary of the invention
The technical matters that the present invention will solve is the defective to prior art, provides a kind of ability the easy method of measuring the heat distortion temperature of plastic edge banding product intuitively.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of heat distortion temperature assay method of furniture thermoplastics edge sealing bar is characterized in that: comprise test process and contrast test;
A, test process carry out according to the following steps:
1), be ready to recirculating air baking box, test board, timer, wherein test board is made up of bracing frame, sample holder and rule, sample holder and rule are fixed on and constitute whole test board on the bracing frame together;
2), be ready to edge sealing bar sample, the length of sample is greater than the distance between the sample holder;
3), according to different samples, the recirculating air oven to initial temperature corresponding with it, is put into test board; Sample holder is placed on the bracing frame, and sample holder comprises two support units, and two support units are separated by a distance, and upper surface flushes each other;
4), the temperature stabilization of recirculating air baking box of waiting to be equipped with test board is during to setting value, sample is placed on the sample holder, with rule with reference to observation 10 minutes;
5), sample has distortion after 10 minutes, the temperature in the rising recirculating air baking box, and then observed 10 minutes does not have then raise the once more temperature of recirculating air baking box and observing again of distortion like sample;
6), through several times raise step by step temperature and observation, begin to fall down distortion until observing sample, record temperature value at this moment promptly is the heat distortion temperature of sample.
B, contrast test carry out according to the following steps:
The temperature of recirculating air baking box is transferred to setting value, puts into test board, the temperature stabilization of recirculating air baking box of waiting to be equipped with test board is put into two comparative sample during to setting value, observes the distortion earlier of which sample, earlier the heat distortion temperature low (poor) of the sample of distortion.
Further, the length of sample is 160-170mm.
Further, the each numerical value that raises of temperature is 5 ℃, and except that last observation, all the other each times of observing are 10 minutes.
Further, test 3-5 sample altogether, get the mean value of all samples at last.
Further, in test process, also comprise the step of each observation process being carried out timing with timer, the each observation all controlled through timer for the assurance of time.
The present invention is through adopting simple equipment; Comprise recirculating air baking box, test board, rule, timer; By recirculating air baking box control temperature, can directly carry out heat distortion temperature and measure the plastic edge banding product, assay method is simple, directly perceived; Measure the product of result itself from reality, therefore more accurate; In addition, because whole assay method is simple, therefore practiced thrift greatly testing cost and test duration.

Fig. 1 tests synoptic diagram for the present invention.
Among the figure, 1 is the recirculating air baking box, and 2 is bracing frame, and 3 is sample holder, and 4 is sample, and 5 is rule.
Embodiment
In the present embodiment, with reference to Fig. 1, the heat distortion temperature assay method of said furniture thermoplastics edge sealing bar comprises test process and contrast test;
A, test process carry out according to the following steps:
1), be ready to recirculating air baking box 1, test board, timer (not shown), wherein test board is made up of bracing frame 2, sample holder 3 and rule 5, sample holder 3 is fixed on rule 5 and constitutes whole test board on the bracing frame 2 together;
2), be ready to 5 edge sealing bar samples 4, can certainly be 3 or 4, length is 160-170mm;
3), according to different samples, the recirculating air oven to initial temperature corresponding with it, is put into test board; Sample holder 3 is placed on the bracing frame 2, and sample holder 3 comprises two support units, and the distance between two support units is just less than 160mm, and upper surface flushes each other;
