In the hot summer, frozen watermelon is indeed a weapon to cool off the heat. As the main tool for frozen watermelon and summer food storage, the refrigerator has penetrated into the lives of all families, and it is inseparable from the refrigerator hinge grease, you know?
There are many types of refrigerators. According to the structure of the door, they can be divided into single-door refrigerators, double-door refrigerators, double-door refrigerators, three-door refrigerators, four-door refrigerators, portable refrigerators, and personal mini refrigerators.
Each refrigerator needs a hinge to connect the refrigerator door to the refrigerator, and the rotation axis of the hinge is used to pull the movement of the refrigerator door box.
When the refrigerator door is not opened and closed, friction occurs between the bottom of the refrigerator and the hinge. If the friction is too large, abnormal noises will be made. Therefore, grease must be added to the hinge's rotating shaft to play the role of noise reduction and lubrication.
According to the different use environment, the requirements for grease are relatively different. The use requirements are mainly lubrication, wear resistance, cold resistance, and long-term leakage.
Specific requirements are as follows:
1. The high temperature is above 70, the grease will not be consumed under high temperature
2. When the low temperature is -40 degrees, the grease will not solidify
3. Good durability, no corrosion to metal
4. Good abrasion resistance and can effectively reduce noise
5. Meet the safety requirements of the food level, non-toxic and tasteless, and meet the h1 level of the US FDA
Some customers make refrigerator hinges, which used to lubricate the rotating shaft with butter or vegetable oil, but the butter is easy to lose for a long time. If it freezes at low temperature, it will volatilize harmful smell.
Vegetable oil quickly turns acid, produces peculiar smell, loses lubricating effect, bacteria multiplies, and easily contaminates the food safety status in the refrigerator. Therefore, this method is not advisable.
Baoxing refrigerator hinge food grade grease has distributed special grease to many famous brands. The main purpose is to reduce the metal friction noise of the rotating shaft. It does not allow long-term circulation. The grease is not consumed at high temperatures, and the grease is not easy to solidify at low temperatures of -40 degrees.
