Problems solved by technology

This method of timing is not synchronous, precise, and cumbersome. Especially when the quantity is large, it is even more inefficient and labor-intensive. I have not heard of a better testing method and device.

Embodiment Construction

[0015] The method for testing the adhesive water resistance of corrugated cardboard, the steps are: (a) fix a suspension device on a support; Connect with an electronic timer 6; (c) place a water tank under the suspension device; (d) hang corrugated cardboard test pieces and counterweights made in accordance with GB / T450 and GB / T 10739 national standards in sequence under the suspension device code, so that the detection switch sends a start timing signal to the timer 6 under the action of the test piece and the counterweight weight; (e) when the corrugated cardboard test piece is soaked in the water in the water tank for a certain period of time, it will be disconnected from the cutout and followed by the weight. When the code comes off, the detection switch sends a stop timing signal to the timer 6, and (f) records the time used by the timer 6, and then determines the adhesive water resistance of the corrugated cardboard.

Abstract

The invention discloses a testing method of glue bond water resistance of a corrugated cardboard and a device thereof. The testing method comprises the following steps: a suspension device is fixed on a stilt; a test piece weight suspension / falloff detection switch is arranged at a proper position of the suspension device and the switch is allowed to be connected with an electronic timer; a watertank is placed below the suspension device, and a corrugated cardboard test piece and a balance weight are sequentially suspended below the suspension device; the detection switch sends a timing start signal to the timer under the action of the test piece and the balance weight, and sends a timing stop signal to the timer when the corrugated cardboard test piece is disconnected from a notch and falls off the weight after being soaked in water in the water tank for certain time; the time used by the timer is recorded and then the glue bond water resistance of the corrugated cardboard is determined. The testing method and the device have the advantages of simple operation, synchronous, accurate and high-efficiency timing and low labor intensity.

Description

technical field [0001] The invention relates to the technical field of testing the moisture resistance of corrugated cardboard, in particular to a method and a device for testing the adhesive water resistance of corrugated cardboard. Background technique [0002] Corrugated cardboard is the main packaging material. my country's corrugated cardboard production ranks second in the world, second only to the United States. According to incomplete statistics, by the end of 2003, there were more than 3,000 corrugated cardboard production lines nationwide, and the output of corrugated cardboard in 2003 was about 15.8 billion square meters. As an important way of commodity outer packaging, corrugated boxes have been deeply rooted in the hearts of the people and have achieved extraordinary achievements. The adhesive water resistance of corrugated cardboard is an important index to investigate the moisture-proof performance of corrugated cardboard. For the determination of corrugated...
