Wada Wear Resistant Natural Rubber Secret  

linatex rubber beltIn traditional rubber productive technology, nature latex is purified, solidified, dewatered, washed, prilled,dried,classified and packaged after collected from the rubber trees and becomes solid natural rubber. In order to shorten the drying time, rubber latex should be crushed and prilled after dewatering, thus the polymer chains will be damaged by shearing force.wada adopts normal temperature and liquid phase mixing process to produce rubber,thus the polymer chains will not be damaged and keep the outstanding inherent properties.From all kinds of molecular weight distribultion curves we can see:in troditional rubber, the long molecular chains are largely destroyed; long molecular chain content is very low;there are a lot of broken chains. And the molecular chain of wada wear-resistant rubber is close to nature rubber, it maximumly keeps the wear-resistant properties of nature rubber.

Wada Rubber Lining  Nanometer Additives 

linatex Natural rubber sheetIn general, traditional rubber has the following problems: It is difficult to maintain the natural rubber polymer chain and uniform mixing at the same time. For this reason, wada discovered excellent powder auxiliary agent,which mixes with nature rubber at normal temperature. wada rubber additives adopt advanced nanometer reinforcing technology, with surface treatment of nano material,which makes the combination between natural latex and auxiliary agent more firm and uniform. Besides, mixed with natural rubber latex in the liquid environment, not only can be uniformly mixed and require fewer doses, and can guarantee high content of natural rubber.With nano coagulator, they can be instantaneously solidified into the rubber in normal temperature, completely eliminate the traditional heating process and guarantee the integrity of rubber polymer chains. It has been clearly proved by the wear test that the wear-resisting property of wada rubber far exceeds the order rubbers.

Superior Performance Security

LinatexVulcanization: Adding the curing agent to semi-finished rubber products, the rubber linear molecular interconnected into a three-dimensional network structure by generating “sulfur bridge”, so as to increase the elasticity of the rubber.Traditional process can’t ensure even heating, especially for large size products,far more external heating than the internal heating,which results in “over cure” of external rubber,and “under cure” of internal rubber. Uneven vulcanization seriously affects the overall performance of rubber products. Wada normal temperature high-frequency curing,adopts high frequency induction heating, which makes the rubber heated evenly and vulcanized at the same time.It not only reduces the vulcanization time, but also improves the quality more even and with excellent overall performance.
