White latex reclaimed rubber in many black reclaimed rubber is very conspicuous, is the production of a variety of white, light-colored reclaimed rubber products ideal raw materials. Because the use of white latex reclaimed rubber production of light-colored, colored rubber products than black latex reclaimed rubber production color of rubber products much easier. However, the use of white latex reclaimed rubber production white or colored rubber products, the rubber surface may appear pan-blue phenomenon, which is why? How to solve it?
Many rubber products companies in the face of latex reclaimed rubber products pan-blue response to the first reaction are looking for reclaimed rubber manufacturers "Zhaobi" that is the result of unqualified white latex reclaimed rubber quality. But the fact is not the case: If the quality of latex reclaimed rubber is poor, how may there be pan-blue problems? The problems caused by the poor quality of reclaimed rubber may not only be as simple as this. White latex reclaimed rubber production surface of the pan-blue, mainly caused by unreasonable formula:
1, in the production of latex reclaimed rubber, reclaimed rubber manufacturers will add a certain proportion of rosin in order to increase the viscosity of reclaimed rubber, improve the processing technology and improve the brightness and elongation of reclaimed rubber. The main component of rosin resin acid, accounting for about 90%, is an unsaturated acid; latex reclaimed rubber products in the formulation of the formula will also add a certain amount of acidic substances; these two acidic substances add up too much, can Strongly absorb ultraviolet light, in the air can be automatically oxidized and induced after oxidation, induced by the surface of latex reclaimed rubber products pan-blue.
Therefore, to avoid the appearance of pan-blue problem on the surface of rubber products produced by the white latex reclaimed rubber and to increase the amount of the alkaline substances in the reclaimed rubber product formula or to reduce the amount of the acid substance,
2, In addition, carbon black oil is also often used in the production of latex reclaimed rubber products, which come from coal tar, which produces carbon black with high quality when incomplete combustion; Oxidation reactions also lead to pan-reclaimed rubber products.
The use of latex reclaimed rubber production of rubber products, we must design a reasonable reclaimed rubber products formula to avoid the formulation of improper design caused by latex reclaimed rubber products pan-blue, yellowing, pan-white discoloration and migration phenomenon.
