1. abrasion resistance test. Use a diameter2inches (3M#7447), the rotating test device with the middle millet color is at room temperature (70±5℉). Every minute.32turn±2turn operation. The liner rotation cycle is200turn/minutes. every hour10minutes. Write down the last10minutes of failed observation.
2. Scratch resistance test. Test UseC-8PRockwell hardness, the test plane is heated, and the kitchenware is kept400°F, the baking pan is kept350℉, the test plane is formed with the pan plane45. Tests to be sustained1hours, until exposed by the tool scratching the bottom layer.
3. ballpoint pen tip. The test equipment is very simple, with a ballpoint pen to compare the scratch resistance of the coating. The pen should be equipped on a piston and a gas valve should be used to give the piston a force. The pressure of the piston is changed by air pressure. The pen is propelled by force and is drawn across the coating. The slip resistance of the coating will be determined by a combination of the force and the length of the coating taken away in the slip.
4. easy release and cleanliness test. The cleanliness of cookware and baking pans and the releasability of food are generally determined by wetting angle and contact angle tests. The contact angle is a measure of how a bead of water adheres to a surface and can be used to figure out how food leaves a non-stick surface. At the same time, the contact angle is also a chemical composition of the food release, or the ease with which the food falls off the surface of the container. Contact Angle Testing: Using the Model100angle meter can test the angle,aG10contact angle test system. For cross-cutting of the coating and the bottom layer to be clearly visible, a cookware or bakeware appliance was prepared to be cut as a test. Make sure that the edges of the cut surface are free of burrs. Wash the sample with alcohol. Minimum sample size is2square inches.

determined using the tangent angle of the water bead to the contact point. If the surface is completely wetted by water, this angle is0conversely, if this angle is180, the surface is not wetting at all, that is to say the greater the contact angle, the better the non-stick properties. For silicone polyester coatings approx.105,PTFEcoating is approximately115.

5. soak test. The main test is detergency and alkali resistance. The alkaline dishwashing powder completely dissolved in water, preparationPH10solution, andPHcard or test strip to detect whetherPH10. Then put the appliance in160℉± 10℉8hours. Then rinse with water. The evaluation of the coating is mainly judged as unqualified by color change, dark gloss, loss of adhesion and bottom exposure. Allow the test equipment to be placed at room temperature without interference.16hours. Use the newly prepared solution to pass at least5cycle, if there is no above-mentioned unqualified phenomenon, it is considered to be passed.
6. resistance to salt and acid tests. Select5exactly the same pan test. The ratio of tomato material to water is50:50. The solution is not29oz plus1/4cup pure non-iodized salt. Stir well. Pour the prepared solution5a test pot and in the lowest230℉2hours. Allow to stand at room temperature until the pan is tested. A pan test5times,24hours a cycle. After testing, the sauce is emptied from the appliance without mechanical means and then tested. Wash in a standard dishwasher, cycle normally, without any detergent, and remove this sauce mixture. After washing the pan, test and evaluate the coating and measure the number and size of blisters (e. g. blisters or no blisters). The total blister area reaches1/2square inch, the test fails.
