The syringe for grease is a special packaging container, generally used in the packaging of dairy cow mastitis, pet nutrition ointment and other drugs, and can also be used as the packaging of grease. Tightness is the basic requirement for the packaging of medicines, and the same is true for greases. So, how to check the tightness of the package?
Grease is made of mineral oil (or synthetic lubricating oil) and thickening agent. It is a grease-like semi-solid. It is mainly used in the friction part of machinery to play the role of lubrication and sealing, such as mixers, valves, Electrical connectors, switch devices, automatic ignition components and other equipment are also used on metal surfaces to fill gaps and prevent rust.
When choosing the packaging of the grease syringe, the manufacturer will pay more attention to the sealing of the packaging. This is because once there is a leakage, it will affect the use of the contents and also affect the brand image of the manufacturer. The sealing of the package can be tested according to the following standards: take an appropriate amount of the plastic veterinary syringe, inject half of the water into the syringe, insert the piston into the plastic gel syringe, remove the protective cap, remove the residual air, and then block with the protective cap, and pass the push rod Apply an axial pressure of 30N on the push rod rubber plug inside the syringe and keep it for 30 seconds. There should be no leakage at the seal of the protective cap and the seal of the piston.
The above detection methods are China's requirements for the sealing test of grease syringe. Of course, different countries may have slightly different test methods for package sealing, but the purpose is to ensure the quality of the package and the stability of the lubricant.
