Cov txheej txheem tsim cov roj hmab foob feem ntau suav nrog cov kauj ruam hauv qab no:
Raw Material Preparation: Ntau yam khoom siv raw, xws li roj hmab, fillers, thiab vulcanizing agents, yuav tsum muaj rau kev tsim cov roj hmab foob. Ua ntej tsim khoom, cov khoom siv raw yuav tsum tau sim thiab npaj.
Kev sib xyaw: Cov khoom siv raw yog muab tso rau hauv lub tshuab sib tov thiab sib tov kom txog thaum homogeneous. Tsim nyog additives yog ntxiv thaum sib tov los txhim kho cov roj hmab ua cov khoom thiab vulcanization nyhuv.
Vulcanization: Cov khoom siv roj hmab sib xyaw yog muab tso rau hauv pwm rau vulcanization, tso cai rau cov khoom sib xyaw kom muaj cov tshuaj tiv thaiv hauv qab cua sov thiab siab, tsim cov roj hmab foob nrog cov qauv ruaj khov thiab kev ua haujlwm.
Ua thiab Moulding: Cov roj hmab vulcanized yuav tsum tau ua tiav thiab molded kom ua tiav cov duab thiab loj.
Kev tshuaj xyuas thiab ntim: Cov txheej txheem roj hmab cov ntsaws ruaj ruaj tau raug kuaj xyuas kom ntseeg tau tias lawv ua tau raws li qhov yuav tsum tau ua. Thaum kawg, cov khoom siv roj hmab uas tsim nyog tau ntim rau kev khaws cia thiab kev thauj mus los.
