Xinhua Xu production technology introduced

Xinhua Xu rubber variety, but the production process, but basically the same. In general solid rubber (gum) as raw materials The basic process of rubber products include: mastication, mixing, rolling, extrusion, molding, curing six basic steps. Of course, raw materials preparation, product finishing, testing and packaging basic process ultimately.

1, Xinhua Xu mastication process: Required by mastication strike a proper plasticity, can only enter the mixing stage. Natural rubber is easy to obtain plasticity, using peptizers obvious effect, high and low temperature can be masticated, when open roll temperature was 45 ~ 55 ?, mixing discharge temperature of 140 ~ 160 ?, screw extruder continuously masticated when the discharge temperature of about 180 ?. Too prone to natural rubber refining, it should be noted.

2, Xinhua Xu mixing process: natural rubber material is easy to eat. For most ingredients wettability is better, with agents dispersed better. Mill, mixing can be. Mixing process does not appear, as some products like synthetic rubber adhesive roll out roll out of pocket, cracked edges, loose pressure and other illnesses, the kneading operation is relatively easy.

3, Xinhua Xu rolling extrusion process: natural rubber rolling out easy, low shrinkage of rubber, rubber products, semi-finished products Yantai size, good shape stability and surface smoothness. Rubber adhesion is good, cord, canvas eraser, when the gum paste, easy-quality semi-finished products is guaranteed.

4, Xinhua Xu curing process: Natural rubber has good curing characteristics: vulcanizing mold, direct steam vulcanization, hot air vulcanization, etc. can be; curing parameters are easy to control, such as the induction period of vulcanization, vulcanization rate regulation and other easy; easy curing operation , rubber fluidity, good adhesion.

Natural rubber has the best overall processing performance, wide range of applications, can be used to manufacture various rubber products, that is to say on the processing equipment, processing conditions than a wide range of adaptability.

Xu Xinhua machining process of rubber products, mainly plastic and elastic properties of the process of resolving this conflict through a variety of technical means, so that the elastic rubber Plastic compounds have become plastic, and then add a variety of ingredients is made semi-finished products and then by curing, semi-finished plastic and has become highly elastic, good physical and mechanical properties of rubber products.

When Xu Xinhua rubber molding, pressing after much pressure, it can not be eliminated because of the ready elastomer cohesion during molding from the mold, often have highly unstable contraction (shrinkage of the rubber, because there are different types of plastic and difference), after a period of time necessary to stabilize gentle.

So, when a rubber products designed from the beginning, regardless of the recipe or mold, are calculated with the need to be cautious, if not, it is easy to produce products dimensionally unstable, resulting in low-quality products.
