How to test the hardness of silicon rubber hose and increase the hardness of silicon rubber hose?
Today Xiaobian to sum up the various difficult problems about silicone tube.Following doubts how test of silicone tube hardness and increasing the hardness of silicon rubber hose?
First of all, there are two kinds of hardness test method of silicone tube, one is the shore hardness test method the other is a shore hardness hardness test.
Shore hardness test method is a dynamic force test, and the test method of static force other than there are essential differences, the main gauge is suitable for determination of ferrous metal and nonferrous metal shore hardness value.Shore hardness tester is easy to carry, large workpiece is especially suitable formetallurgy, heavy machinery industry, such as large components, castings,forgings, crankshafts, rollers, oversize gear, machine tool guidway.
Method of hardness test Shao refers to readings measured by Shaw hardness,its unit is the "degree", the description method of A, C two, which represent different hardness range, test of hard silica gel tube shore A hardness, and the data is gained, the silicone foam hardness meter testing with the shore C and the data is gained, therefore, generally for a rubber or plastic products, at the time of testing, the tester can according to whether the silicone foam, anddecided to use the shore A hardness or shore C hardness meter to test.
Then, if the silicon rubber hose hardness is not enough, then how can increasethe hardness of the silicone tube?
Because the main component of the silicone tube is a vinyl and hydrogen containing silicone oil, it can increase the content of vinyl appropriate andsilicone oil containing hydrogen hydrogen content. And to add some white carbon black and fineness, but also to join the wollastonite powder can increase the hardness. But according to the customer needs to decide.
Finally, the point is that the test method of silicone tube hardness and increasethe hardness of the silicone tube, we hope to effect.
