The use of tire reclaimed rubber production of rubber products can greatly reduce the cost of raw materials, but in the course of use, there is a problem deeply troubled rubber products companies: Tire reclaimed rubber will occur migration. To know that the migration of recycled plastic will not only affect the appearance of recycled plastic products is beautiful, but also affect the performance of recycled rubber products. So what is the performance of tire reclaimed rubber migration, and how to determine the hands of the reclaimed rubber tire will happen to migrate?

Tire rebornable rubber migration is mainly manifested in the surface of reclaimed rubber or product surface yellowing, whitening, pan-blue, etc., usually the type of rubber oil, with the amount of various ingredients: migration of rubber oil or rubber oil overload can lead to Tire reclaimed rubber surface yellowing, excessive use of sulfur can also lead to tire reclaimed rubber and products yellowing; the compatibility of the reclaimed rubber and tire compatibility is not good, excessive use, such as stearic acid and fatty acid consumption will lead to excessive Recycled plastic surface whitening; softener, such as excessive use of rosin can cause the surface of the tire reclaimed pan-blue and so on.

In short, there are many reasons for the migration of recycled rubber. Recently, our technicians learned with a regular customer a simple method of testing the reclaimed rubber for tire reclaimed rubber, which can be used to judge whether the reclaimed rubber will migrate.

The test method is mainly divided in two parts:

1, the detection of tire reclaimed rubber body migration occurs, the use of white paint or spray paint, correction fluid left in the tire reclaimed rubber surface traces of white, usually 3-10 minutes to observe whether there is a white yellowing or black phenomenon to judge Will not migrate

2, the rubber surface after curing leave traces of white, and then 10-30 minutes to observe whether the discoloration.

This method is relatively simple, the results may be detected errors may occur, so rubber products companies can detect the results of this method as a reference to determine the initial tire reclaimed rubber will migrate, if you want to continue to understand the tire reclaimed rubber Whether migration occurs, the reasons for the migration, but also need to conduct scientific and rigorous testing.

The phenomenon of discoloration and migration of tire reclaimed rubber during its use is due in large part to the lower cost of raw materials used by reclaimed rubber manufacturers in order to reduce the use of poor quality carbon black, poor quality rubber oil and other inferior additives. , it will bring a series of irreversible negative effects on the subsequent processing of tire reclaimed rubber products.

Therefore, Xiao Bian reminded the majority of rubber products manufacturers, whether it is to choose a high index of tire reclaimed rubber or ordinary tire reclaimed rubber, must go to the regular manufacturers to buy, regular reclaimed rubber factory tire reclaimed rubber product quality control more stringent, quality It is more stable and less prone to problems. Even if there is a problem, the manufacturer will actively solve it.
