1: Selection of sealing materials

Rubber material: Rubber is a commonly used sealing material. Natural rubber has good elasticity and flexibility, and can fit tightly to the opening and lid edge of the tinplate paint bucket. It has a certain tolerance to the chemicals in the paint and can effectively prevent paint leakage and volatilization. For example, nitrile rubber performs well in oil resistance and is a good choice for sealing oily paint buckets. It can maintain good elasticity for a long time in contact with paint to ensure the sealing effect.

Silicone material: Silicone sealing material has excellent high temperature resistance, aging resistance and chemical stability. Its sealing performance is not greatly affected by temperature changes, and it can maintain good sealing performance in a wide temperature range. Silicone gaskets are ideal sealing materials for tinplate paint buckets that may be stored in different temperature environments. Moreover, silicone materials are non-toxic and will not have adverse effects on the quality of paint.

2: Design of sealing structure

Screw cap design: The tinplate paint bucket with a screw cap is sealed by a tight bite between the threads. The threads of the lid should be designed to be precise and regular, and fit closely with the threads of the barrel. When tightening the lid, the sealing material can be gradually compressed to form a reliable seal. At the same time, in order to prevent the volatilization of paint, the threaded part can adopt a multi-layer sealing design, such as setting a rubber or silicone sealing tape at the thread to further enhance the sealing effect.

Lever Lock Ring Lid : Tinplate bucket with lever lock ring lids use snap-on structures to securely attach the lid to the bucket. This structure usually has a sealing gasket between the lid and the bucket. When the Lever Lock Ring lid is tightened, the gasket is evenly compressed, ensuring that the bucket space is isolated from the outside world. The design of the lever lock ring should take into account its strength and stability, be able to withstand a certain amount of internal pressure, and maintain good sealing performance after multiple openings and closings.
