(1) Water does not pollute the surrounding environment. Compared with mineral oil, it is low in price, pollution-free and non-toxic to the environment when stored and used, and people are more willing to use it cheaply. (2) The environment mentioned here is not just the environment of the earth, but also the environment of the product, such as cleaning up the room or tableware. Any leaks or spills in the hydraulic mechanism simply vaporize without leaving a sticky, greasy, dirty, slippery residue. As much as 85% of all hydraulic fluids eventually leave their system through slow leaks, broken lines of failure or failed parts and seals. (3) The cost of using water as a working medium in hydraulic machinery is much lower than that of mineral oil. So it will be very effective in the long term use of hydraulic machinery instead of oil. (4) Water is not depleted of resources because water can be recycled naturally. Saltwater hydraulic components exist. (5) Tap water is hygienic in industrialized countries, which means there will be negligible product contamination in the event of a leak.Product compatibility, especially in the food, pharmaceutical and chemical industries, provides the difficult replacement benefits of water hydraulic technology. . This importantly provides the system is maintained and well not contaminated with bacteria that can be spread to the surrounding by hydraulic mechanisms.Pneumatic mechanics, which provides a possible choice but requires oil mist lubricant, has high energy consumption, lowers power density . However, care needs to be taken if water hydraulic mechanisms are used in sensitive areas or adjacent leaks are not tolerated by sensitive machinery. (6) Water is not flammable and it is difficult to form a fire hazard. (7) Using water in a production line means that workers Do not breathe in harmful vapor or without exposure to the skin and eyes. (8) Reduce insurance costs due to non-flammable and non-toxic (9) Water thermal conductivity is 4-5 times that of mineral oil (Thostmann and Clausen 1995), which means the water system requires less cooling fluid even without further saving Cost.

PVC RESIN SG3
There are many grades of PVC. The viscosity or K value commonly used in the industry indicates the average molecular weight (or average degree of polymerization) of PVC, that is, the length of the PVC molecular chain, which determines the grade of the resin and the corresponding processing parameters. The molecular weight of the resin is related to the physical and mechanical properties of the product.
PVC Resin is a kind of non-crystalline linear polymer compound. The larger the relative molecular mass, the higher the viscosity, the higher the molecular weight, and the higher the tensile strength, impact strength, and elastic modulus of the product, but the flow of the resin melt Decline in sex and plasticity. The viscosity number is usually used to indicate the molecular weight of the polymer, and the polymer model is divided
PVC used to be the largest general-purpose plastic in the world, and it is widely used. It is widely used in construction materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc
SG3 (K-70, S1300): mostly used for soft products, hoses, wires and cables, films, shoe materials, toys, auto parts etc.
PVC RESIN SG3 has high purity, less fish eyes, easy to blister, high temperature resistance, insulation, soft product texture, etc. It is mainly used to produce soft products such as wires and cables, agricultural films, conveyor belts, and daily plastic products.
