Introduction
Flat rubber seals are rubber products used for flat sealing. They have good elasticity and resilience and can adapt to various surfaces and gaps.
It is mainly used to fill the gap between two planes and provide protection against dust, water, and oil.
The materials of flat rubber seals mainly include natural rubber, nitrile rubber, fluorine rubber, etc.
Processing Technology of Seals
1. Mixing of rubber raw materials: Mix rubber raw materials with processing aids, etc., and perform pretreatment through a high-speed mixer to make them into a highly plastic state.
2. Calendering and extrusion: Put the mixed rubber raw materials into a calender or extruder for molding. In this step, the shape and size of the seal need to be controlled by controlling factors such as pressure and temperature according to the sealing requirements.
3. Cutting and assembly: According to the customer's needs, cut the formed rubber seal to a certain length and then assemble it.
4. Product testing: Qualified seals need to be inspected to ensure they have good weather resistance, wear resistance, and sealing performance.
It should be noted that the processing techniques and processes of different types of rubber seals are slightly different.
FAQs About Flat Rubber Seals
Q: What is the main material of a flat rubber seal?
A: The materials mainly include natural rubber, nitrile rubber, fluorine rubber, etc. According to different usage environments and media, different rubber materials can be selected to meet usage requirements.
Q: How to choose the appropriate flat rubber seal?
A: When deciding a suitable flat rubber seal, you need to consider factors such as the use environment, sealing performance requirements, installation method, and cost. For example, for high-temperature and corrosive environments, you need to pick high-temperature and corrosion-resistant materials, such as fluoro rubber; for general mechanical equipment and vehicle seals, you can select nitrile rubber or natural rubber. In addition, customized production needs to be carried out according to actual needs to meet the special requirements of customers.
Q: How to solve the problems that occur during the use of a flat rubber seal?
A: During use, a flat rubber seal may have some problems, such as bubbles and uneven hardness. Corresponding measures can be taken to solve these problems. For the issue of bubbles, you can eliminate the air during the mixing process by optimizing the mixing process, increasing the cooling time, or using vacuum degassing equipment; for the problem of uneven hardness, you can accurately control the proportion of each component to ensure the quality of the mixed rubber.
