That waterproof grease you're using, is it really waterproof?
In the essential parts of waterproof sealing, such as: sanitary products, household appliances, all kinds of waterproof rings, waterproof piston position and waterproof sleeve need to use waterproof grease. Waterproof seals are often in contact with water in various forms: steam, emulsion, rain or, more commonly, water present in pressure ejectors or cooling facilities. Products to be in contact with water. The above location will often be in contact with water and steam or various types of alkaline or weakly acidic water, therefore, the requirements for waterproof lubrication grease are particularly strict and harsh. One of the first functions of waterproof greases is to effectively participate in system sealing. Insoluble in water, water does not emulsify. There are many types of waterproof greases, and different greases should be selected in different working conditions. So how to judge the effect of waterproof sealing grease is good? The method of judging the effect of waterproof sealing grease can be viewed from the following 5 aspects: ①. Waterproof performance test: Waterproof performance test can be carried out to evaluate the effect of waterproof sealing grease. This can be done by applying the lubricant to a test device under a known water source to see if the lubricant can maintain stable and effective lubrication under water. ②. Sealing performance check: check the sealing performance of the parts lubricated by the lubricant. A grease with good sealing performance should be able to effectively prevent impurities such as moisture and dust from entering the lubrication part and protect the equipment from corrosion and wear. (3) Wash resistance: The wash resistance of the grease refers to whether it can adhere to the friction surface under the water flow and maintain a stable lubrication effect. A good waterproof seal grease should be able to withstand the impact of water flow and maintain lubrication. (4) Hydrolysis resistance: the grease should have good hydrolysis resistance in the water environment, that is, it will not rapidly decompose or fail due to the action of water. This can be judged by checking the stability and durability of the grease in water. ⑤. Long-term water resistance: For long-term use of equipment, it is necessary to evaluate the long-term water resistance of the lubricant in the water environment. This can be assessed by monitoring and recording in real applications to see if the lubrication state is continuous and stable.
