Function

The meaning and function of sealing lining the sealing lining, commonly known as lid lining, refers to the lid and lining material which can produce a tight sealing effect with the container. Here, containers refer to glass bottles, plastic bottles and metal cans. There are various types of covers, including screw caps, drag covers, cap caps, crimping caps, pressure caps. Lining materials refer to the materials that can close the lid and container tightly, Materials with certain requirements and specifications are absolutely free of leakage. To ensure the performance of packaged goods remains unchanged, for example, if the cover is used only and there is no lining at the bottom of the cover, the sealing effect is difficult to achieve. The function of lining is huge

Factors Affecting Sealing

Fluid properties: the viscosity of the liquid has a great impact on the sealing performance of the packing and gasket. The fluid with high viscosity is easy to seal due to its poor fluidity. The viscosity of liquid is much higher than that of gas, so liquid is easier to seal than gas. Saturated steam is easier to seal than superheated steam because it will condense and precipitate droplets and block the leakage channel between sealing surfaces. The larger the molecular volume of the fluid, the easier it is to be blocked by the narrow sealing gap, so it is easy to seal. The wettability of the liquid on the sealing material also has some influence on the sealing. The liquid which is easy to soak is easy to leak due to the capillary action of the micro pores in the gasket and packing.
