Function of reclaimed latex in pure rubber pipe时间：2021-10-22浏览次数：732
Latex reclaimed rubber is the product of processing waste natural rubber, waste latex gloves, waste latex balloons, and waste latex hoses. It has high glue content and good elasticity. The biggest task is to replace natural rubber, consume rubber products, and reduce costs. At present, many pure rubber tubes in the market are made of natural rubber, such as medical hoses and vacuum rubber tubes; However, the high price and volatile price of natural rubber make many manufacturers feel headache. Can latex reclaimed rubber also replace natural rubber to consume pure rubber pipes? What are the functions and needs to pay attention to?
The raw materials of latex reclaimed rubber include waste rubber cups, rubber wires, waste rubber materials of latex products and all kinds of waste latex products, so that some latex reclaimed rubber will participate in a certain proportion of ground natural rubber in the processing process, which is processed through multiple processes such as crushing, desulfurization and filtration. Its effective rubber hydrocarbon content is higher than that of other kinds of reclaimed rubber. The fundamental performance of latex reclaimed rubber and natural rubber is different, and it has good compatibility with natural rubber, It can be used with natural rubber or used alone to replace natural rubber. It can consume all kinds of pure rubber pipes with high elasticity and high strength, and reduce the cost.
Replacing a certain amount of natural rubber in pure rubber pipes with low-cost latex reclaimed rubber can not only reduce the raw material cost, but also improve the process performance of the rubber, as detailed below.
The reclaimed latex has good plasticity and mobility, and the power consumption is small, which can improve the rubber processing technology and energy consumption; The recycled latex rubber processed from waste natural rubber and waste latex products has reduced shrinkage and good dimensional stability after refining and other processes in the consumption process, so the pure rubber pipe is not easy to shrink and deform in the consumption and application process; Natural rubber has poor anti-aging performance, and the anti-aging performance of latex reclaimed rubber is better than that of natural rubber, which can reduce the amount of antioxidant and delay the aging time of pure rubber hose; Natural rubber has high mechanical strength and good elasticity, but it is easy to produce vulcanization reversion during vulcanization molding. The vulcanization performance of latex reclaimed rubber is good, which can just reduce the vulcanization reversion of pure rubber tube and improve the safety of scorch.
The use of latex reclaimed rubber in natural rubber pure rubber pipes can not only reduce the cost, but also improve the rubber processing technology. Does this mean that all latex reclaimed rubber can replace natural rubber to consume pure rubber pipes, and the more the amount of latex reclaimed rubber in pure rubber pipes, the better? Can the answer be decided. Although latex reclaimed rubber has great advantages in replacing natural rubber to consume pure rubber pipes, for pure rubber pipes with particularly high mechanical strength requirements, a large number of latex reclaimed rubber will reduce the physical and mechanical strength of the rubber to a certain extent, which should be reasonably controlled; In terms of natural rubber and pure rubber in the field of medical treatment and life, it is required to use environmental friendly latex reclaimed rubber and odorless latex reclaimed rubber in the formula of rubber tube; The formula of pure rubber pipe containing latex reclaimed rubber also needs to be adjusted.
In practical consumption, latex reclaimed rubber completely or partially replaces natural rubber. When consuming pure rubber pipes, we must carefully choose the type of latex reclaimed rubber, reasonably control the amount of latex reclaimed rubber, and try to increase the amount of latex reclaimed rubber and reduce the consumption cost on the premise of ensuring the quality of natural rubber pure rubber pipes.
