The rubber seals produced with natural rubber as the main raw material have good mechanical strength, flex resistance and electrical insulation; latex reclaimed rubber is waste natural rubber, waste latex products are sorted, picked, crushed, desulfurized, filtered after being recycled. Recycling resources processed by refining multiple processes, the main purpose is to replace natural rubber to produce rubber products to reduce costs; the use of appropriate amount of latex reclaimed rubber in natural rubber seals is an ideal way to reduce costs, but in actual production, latex The role of reclaimed rubber can be more than that.
1. The role of latex reclaimed rubber in natural rubber seals
1Reducing costs: The high price and fluctuation of natural rubber are obvious to all. The price of latex rubber reclaimed rubber processed from waste rubber and waste rubber products is low and basically in a stable state. Therefore, latex reclaimed rubber is the first in natural rubber seals. One function is to reduce the cost of raw materials; when rubber latex reclaimed rubber is used in natural rubber seals, the fluidity and plasticity of the rubber compound are better, and the energy consumption during processing is significantly reduced, which can reduce the power consumption in the production process.
2 Improve the process: the latex reclaimed rubber has small vulcanization and good vulcanization flatness. The latex reclaimed rubber can be used in the rubber seal with natural rubber as the main raw material to improve the vulcanization performance of the natural rubber.
3 improve performance: reclaimed rubber products have small expansion and contraction, latex reclaimed rubber is used in natural rubber seals to improve the compression resistance of seals; natural rubber seals are elastic, wear-resistant and flex-resistant, but in use It is easy to age in the process, and the latex reclaimed rubber can improve the aging resistance of the rubber to a certain extent.
2. Tips for mixing latex reclaimed rubber in natural rubber seals
1There are many kinds of rubber seals. Generally, black and dark rubber seals use black latex reclaimed rubber, white and light color seals choose white latex reclaimed rubber; 2 for natural rubber seals with environmental protection and odorless requirements, The use of latex reclaimed rubber to improve the process and reduce the cost requires the use of environmentally-friendly latex reclaimed rubber and odorless NR reclaimed rubber; 3 for rubber seals with particularly high elasticity and mechanical strength, the amount of latex reclaimed rubber should be reasonably controlled; A common rubber seal can be used in a large amount of latex reclaimed rubber or even completely using latex reclaimed rubber. 5 The rubber seal formulation with latex reclaimed rubber needs to be adjusted in time.
When rubber products manufacturers use latex reclaimed rubber to replace rubber gels in whole or in part to produce rubber seals, according to actual needs, the types of latex reclaimed rubbers, latex rubber reclaimed rubber, and rubber seal formulations containing latex reclaimed rubber can be selected to ensure quality. Under the premise of reducing raw material costs and production costs, to achieve a win-win quality and cost.
