1. Internal mixing txheej txheem
Internal mixing yog sib tov cov pa roj carbon dub, roj hmab ntuj los yog hluavtaws roj hmab, roj, additives, accelerators thiab lwm yam raw cov ntaub ntawv ua ke thiab ua lawv nyob rau hauv ib tug tov khoom los tsim roj hmab. Qee tus neeg piav txog cov txheej txheem no raws li lub khob noom cookie txuas hauv kev ua noj.
2. Kev npaj cov khoom siv roj hmab
Hauv qhov txuas no, nws feem ntau siv rau theem ua kom tiav tag nrho cov khoom siv roj hmab semi-tiav uas ua rau lub log tsheb.
(1) Tshooj I: extrusion
Cov roj hmab ntxiv rau lub taub hau extruder kom extrude sib txawv ib nrab ntawm cov roj hmab, xws li tread, sidewall, daim duab peb sab roj hmab strip, thiab lwm yam.
(2) Nqe II: Rolling
Cov khoom siv raw cord hla lub calender, thiab ib txheej nyias ntawm cov roj hmab yog dai rau ntawm ob sab ntawm txoj hlua, thiab thaum kawg ua tiav rau hauv hlua ntaub. Cov khoom siv raw cov hlua feem ntau yog siv nylon thiab polyester.
(3) Tshooj III: hlaws txoj kev
Lub hlaws yog tsim los ntawm winding ntau steel hlau tom qab dai kua nplaum. Cov khoom siv rau cov hlaws muaj qee yam tshwj xeeb. Tom qab vulcanization, cov khoom sib txuas thiab cov hlau hlau tuaj yeem sib txuas ua ke.
