Do plastic water cups exported to the global market need to be tested for dishwashers

Why do drinking glasses need to be tested for dishwashers?

Dishwasher has become very popular in European and American markets, but in China the dishwasher market is still among high-income people in first- and second-tier cities, so the Chinese water cup market does not require plastic water cups to pass the dishwasher test. What exactly is the purpose of dishwasher testing? Why is it necessary to do a dishwasher test?

The purpose of dishwasher testing generally includes the following. During the cleaning process of the test water cup, will the pattern printed on the surface of the water cup fall off? Will the spray paint on the surface of the test water cup fade? Will the test water cup be deformed due to long-term cleaning at high temperatures in the dishwasher? Will the test water cup show obvious scratches after being washed through the dishwasher?

Why do we need to conduct these tests? We need to understand the dishwashing principles of dishwashers. The working standards and principles of dishwashers currently on the market are all modeled after European dishwashers. Although some domestic brands have strict requirements on the washing pressure and washing pressure in dishwashers. The method has been updated, but generally the dishwashing methods and principles are still the same. A standard operation of the dishwasher takes about 50 minutes, and the internal temperature is about 70°C-75°C during operation. When the dishwasher is working, the items inside the dishwasher are completely cleaned by moving the water jets at various angles. The items inside the dishwasher do not rotate like what most friends understand by a washing machine. For example, water cups, bowls, plates and other items are fixed on the washing rack. motionless.

After understanding this, the editor can answer the question of whether plastic water cups must pass the dishwasher test. Usually, passing the test according to the standard requires at least 10 consecutive tests to pass the test without any problems. Then the pattern test and obvious scratches are no problem for the plastic water cup dishwasher test. Fading and deformation are the most critical reasons why many plastic materials fail to pass the test. Among them, high temperature deformation is also the essential property of many plastic materials that cannot be changed. of. Therefore, the global market does not have strict requirements for plastic water cups to pass the dishwasher test.
