Silicone tube: silica gel hardness can be reduced its hardness?
In the production of silicone rubber hose may be due to a small mistake to make its high hardness, how to do? How can ability reduce its rigidity, reach the target of product? Has made the end of the silicone tube is unable to change its hardness, here is a silicone has been vulcanized. Method mainly has the following several:
First, if you do not consider the cost of the case to increase the amount of oil can also be appropriate to reduce the number of carbon black. If there is no production of basic silicone material, it is essential to increase the amount of oil in the formula.
Second, or to see what is the material of silicone tube products, so that it continues to be vulcanized, to the vulcanization, can also reduce the hardness, but the performance of the product is not guaranteed.
Third, you can use the oven to make the surface of the product back to the original, so as to achieve the purpose of reducing the hardness, but to ensure that the number of degrees to reach.
The above 3 methods are in reducing the hardness, but the first method is good, but the cost is very high, is not cost-effective; the second is the quality of the product can not be guaranteed very well; the third method is feasible, but it is difficult to reach the degree index.
Silicone rubber hose manufacturers analysis: silicone hose hardness is high, the first is to check which part of the problem, to prevent the problem from happening again; is the design stage, or the stage is not ready to do it? Or improper molding process design, resulting in the change of the two sulfur process caused by the change; or silicone material mix it?
