Abstract
An absorbent thickness expansion ratio tester comprises a tank for containing water. A water inlet is arranged on the upper portion of the tank, a water outlet is arranged on the lower portion of the tank, a water temperature control device is arranged in the tank, TS test piece fixtures and sensors are arranged at the bottom of the tank, and the sensors are displacement sensors or stress sensors. By the aid of an improved testing device, thickness measurements of a same spot on a plate before and after soaking are realized, meanwhile, by the aid of the fixtures in the tester, that TS test pieces are placed perpendicular to a liquid level is guaranteed, and test errors are greatly lowered. The water-sucking thickness expansion ratio tester is further capable of realizing online testing and recording data change of the TS test pieces during the testing process in real time, and accordingly performance of the test pieces is better reflected.
Description
Technical field
The utility model belongs to artificial board thickness swelling rate detection technique field, particularly a kind of tester that is used for accurately measuring the wood-based plate thickness swelling rate.
Background technology
Thickness swelling rate (TS) is a very important index in wood-based panel product, and it has reflected the water resistance and the dimensional stability of product, and the TS value is high more, and water tolerance is poor more.Though the directly situation of immersion of wood-based plate seldom takes place in actual use, measure its thickness swelling rate, can roughly judge the dimensional stability when wood-based plate in use changes with surrounding enviroment humidity.The sheet material of poor water resistance if edge sealing is not tight all around, can takes place to cause size and Strength Changes than marked inflation, and then influence the use of board product under wet environment.At present; The test of wood-based plate thickness swelling rate (TS) is mainly with reference to standard GB/T 17657-1999: with stay-in-grade test specimen be soaked in that the pH value is 7 ± 1, temperature is in 20 ± 2 ℃ the tank; Vertically place and guarantee test specimen free expansion; Measure and calculate the thickness swelling rate value at the appointed time, measurement is the thickness measure before and after employing spiral dial gauge absorbs water, and in practical operation; The one, work is loaded down with trivial details tediously long; The 2nd, what be difficult to accurately measure before and after can occur measuring is same point and cause test error, and can't carry out on-line monitoring, the 3rd, and can exist and can't realize in the GB placing and have certain error perpendicular to liquid level.
The utility model content
Goal of the invention: to above-mentioned technological deficiency; The utility model provides a kind of thickness swelling rate tester; Through improved testing apparatus, realize the thickness measure before and after the same point immersion on the sheet material, simultaneously through the anchor clamps in the tester; Guarantee that the TS test specimen is perpendicular to liquid level and places, significantly reduce test error; This device can also be realized online detection, and the data variation of real time record TS test specimen in test process better reflects the performance of test specimen.
Technical scheme: the thickness swelling rate tester, comprise a casing that is filled with water, casing top is provided with water inlet; Lower box is provided with freeing port; Be provided with water temperature control device in the casing, bottom half is provided with TS piece fixture and sensor, and said sensor is displacement transducer or strain gauge.
The facade of said casing has at least one side transparent.
Said TS piece fixture comprises lifting table and test specimen folder, and said test specimen is located on the lifting table, and test specimen folder top is provided with thimble, and test specimen folder bottom is provided with the base locking pin.
The other sensor support frame that is provided with of said TS test specimen folder.
Said displacement transducer is magnetostrictive displacement sensor or laser displacement sensor.
Said thimble and base locking pin adjustable and retractable length.
Beneficial effect: this instrument adopts the variable quantity of displacement transducer test specimen thickness or length, with test thickness swelling rate or linear expansion rate; Attemperating unit can satisfy the test request (comprising high low temperature) under the different temperatures; Displacement transducer and strain gauge can satisfy the requirement of wet stress measurement; Apparatus subject has one side to adopt the organic glass manufacturing, can observe test specimen expansion process.Lifting table is mainly used in the placement of test specimen and takes out the thickness swelling rate unit clamp and take the thimble-type fixed mode, and the upper end is that scalable is fixed, and can satisfy because of the accurately fixing purpose of the sawing error of test specimen.Sensor reading adopts digital simulation to carry out interpretation of result.
