Reason and solution of silicone tube with bubble
The production technology of silicone rubber tube is a technology live, it may cause a small mistake will cause the problem of silicone rubber hose has bubble and so on.
The reasons and solutions of the bubbles in the silicone rubber hose are shared in the following.
First, if the silicone rubber hose used in the raw materials of too many impurities, mixed, uneven, and so on, can produce such a phenomenon. In
Mixed with other things, such as the PE bag of packaging rubber. The product structure is complicated and the mold structure is not reasonable, the beggar
Difficult to discharge. If there is a vacuum, it is recommended to do the vacuum. Suggestion can be added some processing flow and exhaust gas. Mixing time
Enough curing pressure is insufficient, mould or plastic material with impurities or oil, water, improper way of loading, involved in the air, vulcanization
Temperature is too high.
Second, if the silicone hose operating oil contains too much water, it is easy to have water, I do not know whether the bubble is small attached to the production
Product surface? If it is, it should be water. Bubble is very common, the best solution is to compare the test, such as your formula to the outside
The surface of a point, a look at the cure, you can rule out the raw material. If the material is not affected in the determination of moisture, and zinc oxide moisture or
Rotten eye or white spots, generally not a bubble, instead of just under stearic acid because of stearic acid, plant a large area of bubble steam.
Is not a bubble, a drum bubble, fried type vesicles, say like drum clubbing, most of the curing system and process with no
OK, you just drop the temperature a little, a little longer, to see the results you know.
Third, if it is to open the mixing of the words, silicone tube has small bubbles, usually there are three reasons:
1 rubber packaging PE bag is not cleaned up, and PE in the low temperature mixing can't plasticizing;
2 filler or oil, containing water, or volatile;
The 3 part of the complexing agent such as poor dispersion, antioxidant RD, or ancient Malone, resin, granular materials;
In a word, the temperature of the silicone tube is too low, the degree of mixing is not enough, the dispersion degree is not enough.
As far as. Don't think that is less sulfur; observed by blade to vesicles, if there is a yellow thing is RD problem, because
As if rubber hardness is low, RD is not easy to break up. The oil is more, if added together and carbon black carbon black to cause.
In the group, the shape of the bubble, if it is not the rule of the material is the material dispersion problems such as RD, film, etc.; if it is round
It may be water or other, but it is unlikely to be a problem of water.
