Waterproof sealing lubricants are widely used in various industries, suitable for all kinds of sanitary ware, household appliances and other industries, and there are static and dynamic differences in waterproof sealing.
Static waterproof seal means that the sealing position does not move relative to each other. If the watch shows a waterproof level, use waterproof sealing lubricant. This is a static seal, which is relatively simple.
This article focuses on dynamic sealing. In terms of movement form, there are piston type, gear pump type, shaft type, etc., among which the waterproofing of gear pump type is very complicated.
Take the gear pump as an example. When the waterproof grease contacts the gear surface, it has the effect of vacuum pumping. Grease has been in contact with water for a long time, and the grease has rolling friction during the gear meshing process. Both of them have a considerable test on the grease. If you choose a high-viscosity oil, the speed will slow down, and if you choose a low-viscosity oil, it will be washed away by water.
Take the mixer as an example. Grease plays a lubricating role between the shaft seal and the shaft. Poor lubrication will cause noise and shaft seal wear. The customer's product life test meets the requirements. After the finished product is stored for a period of time, the starting resistance is large or the seal cannot be sealed. What kind of grease can effectively waterproof and seal? It is necessary to choose an effective waterproof sealing grease.
First of all, considering that the grease does not corrode the seal ring and plastic parts, the viscosity of the grease should be adjusted according to the hardness of the seal ring to prevent the grease from being absorbed by the seal ring.
Secondly, consider the safety requirements of NSF H1 food grade, RoHS, REACH and other safety regulations.
Third, the requirements for waterproof and sealing function. Lubricating grease is composed of base oil, thickening agent and additives. It is the thickening agent that determines the waterproof and sealing function of the grease, and composite aluminum and calcium oxide are the best. The complete TDS has technical parameters for waterproof cleaning test. This is an important parameter for waterproof sealing, such as ASTM D-1264 less than 5%, DIN51807 0-90.
