Of all, this belt mark is primarily acquired from the manufacturing process of silicone tube. In the standard process, the silicone tube mold is extruded out as well as there is usually a high temperature oven to cross-linked element vulcanization the silicone tube.
Reasons for belt marks in silicone hose manufacturing
It can make a preliminary shape of the silicone tube, that is, the surface of the silicone hose is primarily mature, however the wall surface density of the inner silicone is not totally vulcanized, so it requires to be vulcanized again in the baking channel. By doing this, a stove between the cooking network and also the extruder will not have the problem of belt marks, since the silicone hose elbows surface of the silicone tube has been treated and also created. Also if it is placed on the conveyor belt, there will be no belt marks!
When it comes to the problem of belt marks, the absence of stove procedure will certainly bring about this problem externally of the silicone tube.because the silicone tube right away gets in the conveyor belt of the cooking network after extrusion at the mold mouth for sulfurization.
Keep in mind that the surface area of the silicone tube right now is not vulcanized, or reveals the state of silica gel after intensive training, just through the launch of the mold mouth of the threaded pole (right now, The soft silica gel is quickly boosted by the exterior will certainly leave traces) and also the conveyor belt of the cooking road will not be changed daily, with the continuous aging of the conveyor belt or constant insufficient and adsorption of dirt, right now, the silicone tube stuck to the conveyor belt, will immediately appear unequal surface, that is, the resource of belt marks, before the baking roadway has actually developed a belt mark, After baking can not alter the surface area of the silicone tube, so after forming there will be this situation.
Why not include an oven procedure to the extrusion tools and cooking course to resolve the belt marks?
Should be part of the fairly little area or because of expense considerations, in the enhancement of a heat stove process nonstop heat irradiation is more waste of power, so in the eyes of some suppliers will decrease such a stove can additionally conserve a great deal of electricity.
