After weighing the amount of mixing rubber and vulcanizing agent, the next thing to do is to add vulcanizing agent, it is recommended to follow the following steps to complete.
1, first clean the open mixing mill's hygiene, to secure its cleanlines to prevent the mixing of other impurities. then the open mixing mill's roll pitch is adjusted to the minimum, the rubber mixer into the open mixing mill for thin pass. after the thin pass, the roll pitch of the machine is enlarged appropriately so that the compounding rubber is evenly wrapped on το ρολά. Η επιφάνεια θερμοκρασία του το σύνθεση καουτσούκ πρέπει να περίπου 80 βαθμός .
2, by adjustmenting the roll distance and appropriate cooling water to control the temperature of the compounding rubber at about 60 ~ 80 degree C, at this point, the vulcanizing agent into the compounding rubber to start.
Putting attention to:
a, to put the vulcanizing agent evenly into the compounding rubber, and do not concentrate in one place.
c, to fall to the drum below the vulcanizing agent and then put into the compounding rubber.
3, and so can not see the vulcanizing agent as well as the vulcanization accelerator after the start of cutting, left and right twice each. to let the vulcanizing agent and the vulcanization accelerator better dispersed to the mixing rubber, can be confirmed by observing the form of the vulcanizing agent and the vulcanization accelerator: if it is a solid into a sticky silk, and Στη συνέχεια αναμεμειγμένο στο το καουτσούκ, so the mixing effect is good.
4,Take out the compounding rubber for thin pass. When thin pass, the open mixing mill's roll distance should be adjusted to the minimum; the number of thin pass in 4~5 times.
Out of the sheet must be in accordance with the thickness required by the product molding. The whole process needs to be noted that the completion time is not too long, other it will reduce the Menny viscosity and physical properties.
