Lub tshuab ua roj hmab piav qhia cov txheej txheem ntawm kev hloov cov ntaub ntawv yooj yim rau hauv cov khoom siv roj hmab nrog cov khoom tshwj xeeb thiab cov duab.Cov ntsiab lus tseem ceeb suav nrog:
- Roj hmab compounding system:
Cov txheej txheem ntawm kev sib txuas cov roj hmab nyoos thiab cov khoom siv ntxiv raws li kev ua tau zoo ntawm cov khoom, xav txog yam xws li kev ua haujlwm thev naus laus zis thiab nqi.Cov txheej txheem kev sib koom ua ke suav nrog cov roj hmab nyoos, vulcanization system, qhov cuab yeej siv zog, kev tiv thaiv kab mob, plasticizer system, thiab lwm yam. Qee lub sij hawm nws kuj suav nrog lwm cov tshuab tshwj xeeb xws li nplaim hluav taws xob, xim, foaming, anti-static, conductive, thiab lwm yam.
1) Raw roj hmab (los yog siv ua ke nrog lwm cov polymers): niam txiv cov khoom los yog cov khoom siv matrix
2) Vulcanization system: Ib qho kev sib cuam tshuam nrog cov roj hmab macromolecules, hloov cov roj hmab los ntawm linear macromolecules rau hauv peb-dimensional network qauv, txhim kho cov khoom siv roj hmab thiab stabilizing nws morphology.
3) Kev siv lub zog ntxiv: Ntxiv cov khoom siv ntxiv xws li cov pa roj carbon dub lossis lwm cov khoom ntim rau cov roj hmab, lossis txhim kho nws cov khoom siv kho tshuab, txhim kho cov txheej txheem kev ua haujlwm, lossis txo cov nqi khoom.
4) Kev tiv thaiv kab mob: Ntxiv cov tshuaj tiv thaiv kev laus kom ncua kev laus ntawm cov roj hmab thiab txhim kho lub neej kev pab cuam ntawm cov khoom.
5) Plasticizing system: txo cov hardness ntawm cov khoom thiab viscosity ntawm cov roj hmab sib xyaw, thiab txhim kho kev ua haujlwm.
- Kev siv technology ntawm roj hmab:
Tsis muaj teeb meem dab tsi ntawm cov khoom siv roj hmab, nws yuav tsum dhau los ntawm ob txoj kev: sib tov thiab vulcanization.Rau ntau cov khoom siv roj hmab, xws li hoses, tapes, log tsheb, thiab lwm yam, lawv kuj yuav tsum tau mus txog ob txheej txheem: dov thiab extrusion.Rau cov roj hmab nyoos nrog siab Mooney viscosity, nws kuj yuav tsum tau molded.Yog li ntawd, cov txheej txheem tseem ceeb tshaj plaws thiab tseem ceeb tshaj plaws hauv kev ua cov roj hmab muaj xws li cov theem hauv qab no:
1) Refining: txo qhov hnyav molecular ntawm cov roj hmab nyoos, ua kom plasticity, thiab txhim kho kev ua haujlwm.
2) Kev sib xyaw: Sib tov tag nrho cov khoom xyaw hauv cov mis sib npaug kom ua cov roj hmab sib xyaw.
3) Rolling: Cov txheej txheem ntawm kev ua cov khoom tiav ib nrab ntawm qee qhov tshwj xeeb los ntawm kev sib xyaw roj hmab lossis siv cov khoom siv pob txha xws li textiles thiab steel xov hlau los ntawm kev nias, molding, kev sib txuas, so, thiab kev ua haujlwm gluing.
4) Nias: Cov txheej txheem ntawm nias cov khoom ua tiav nrog ntau ntu ntu, xws li cov raj sab hauv, tread, sidewalls, thiab roj hmab hoses, tawm ntawm cov roj hmab sib xyaw los ntawm lub qhov ncauj.
5) Vulcanization: Cov kauj ruam kawg hauv kev ua cov roj hmab, uas muaj cov tshuaj tiv thaiv ntawm cov roj hmab macromolecules los tsim kev sib txuas tom qab qee qhov kub, siab, thiab lub sijhawm.
