耐油性

Oil resistant

在试样表面上分别涂奶油、菜油、豆油，40±2℃，每24h擦去旧的，抹上新油，连续168h，试验后观察接触面是否溶胀、变色、硬化Cream, vegetable oil and soybean oil were smeared on the surface of the sample at 40±2℃. The old ones were wiped off every 24 hours and the new ones were smeared on for 168h. After the test, observing whether the contact surface was swollen, discolored or hardened.
