The testing machines are manufactured according to the national standard or European standard and American standard to test whether the products produced by the manufacturer are contractual. The standard codes are generally GB, QB, ISO, EN, JB and so on.
The carton burst tester is the maximum pressure that paper and paper can withstand uniformly increased per unit area. The burst strength tester is used to test the burst strength value of carton board. It adopts digital display pressure. When the sample breaks, the maximum burst strength value is automatically retained, and the test results can be printed in the trend. Generally, the indication mode of the burst strength tester is digital.
Burst test machine is divided into carton burst resistance and base paper burst resistance. These two tests can be measured with the same instrument, but the bursting membrane used for carton burst resistance and base paper burst resistance is different. The rupture-resistant film of the carton is thicker, and the rupture-resistant film of the base paper is thinner, and the measurement of the rupture-resistance of the base paper is generally used in the carton factory. The direct customers of the carton factory only need to test the rupture resistance of the carton.
There are three types of burst testers on the market: the first one is a fully automatic burst tester, which is also more accurate for testing data on cardboard, paper or cartons. Once the test button is pressed, the automatic test is completed and the data is automatically saved. The downside is that this instrument is pneumatic and requires an air pump or air source.
The second is the semi-automatic burst tester. This instrument was used for cardboard and leather a few years ago. The disadvantage of this instrument is that it requires personnel to tighten and loosen the pressure plate every time a test is performed. The data is also relatively unstable, and the price is also more expensive than the previous automatic burst tester. Except for some leather blasting, it is difficult to see this instrument on the market now.
The third type is the manual burst tester. This instrument is the earliest burst tester on the market. It is basically no longer on the market because this instrument is not only cumbersome, but also very troublesome to operate. Compared with the previous two burst testers, this instrument does not have any advantages, so this instrument is gradually eliminated.
Here comes the point: none of the above three instruments can meet the standard requirements of 0-100kg/cm2. Note that no instrument can achieve, achieve, and achieve, and important things are said three times.
Although no manufacturer can achieve this data, there are still many manufacturers who write the test range of 0-100kg/cm2 on their technical parameters. In the final analysis, it is because no one can produce such a high resistance cardboard. The fact I have not seen many manufacturers that have a bursting strength of over 20kg for the upper cardboard in my years of practice.
After knowing that you need the carton burst testing machine, you can ask the merchant to show you the operation panel of the instrument. Now the automatic burst testing machine is divided into touch screen and LCD, and the touch screen is tall and has a curve display. In addition, and, no, have, what, what, use, and the liquid crystal carton burst test machine is better than the touch screen carton burst test machine in all aspects because of its mature technology.
However, it should be noted here that there is also a low-end software carton burst tester. This software can only display the maximum peak force value of the cardboard tested, and this software has certain risks in terms of operation. It will cause harm to the testers, but because the cost is cheaper than the previous two, some unscrupulous manufacturers will sell this instrument as a liquid crystal type to the customer because the customer does not know it, so pay attention to this.
