Tom qab ntsuas qhov sib xyaw ntawm cov roj hmab thiab cov vulcanizing tus neeg sawv cev, qhov tom ntej yuav tsum ua yog ntxiv cov vulcanizing tus neeg sawv cev, nws raug nquahu kom ua raws li cov kauj ruam hauv qab no kom tiav.
1, ua ntej ntxuav qhov qhib sib tov zeb kev tu cev, kom nws huv si kom tsis txhob sib tov ntawm lwm yam impurities. Tom qab ntawd qhov qhib sib tov zeb yob lub suab yog kho kom tsawg, cov roj hmab tov rau hauv qhov qhib sib tov zeb rau nyias dhau. Tom qab nyias dhau lawm, yob lub suab ntawm lub tshuab yog loj kom tsim nyog kom cov roj hmab compounding sib npaug ntawm cov yob. Qhov kub ntawm cov roj hmab compounding yuav tsum nyob ib ncig ntawm 80 degree.
2, los ntawm kev kho cov yob nrug thiab cov dej txias kom tsim nyog los tswj qhov kub ntawm cov roj hmab sib xyaw ntawm li 60 ~ 80 ° C, ntawm qhov no, tus neeg sawv cev vulcanizing rau hauv cov roj hmab compounding pib.
Tsom ntsoov rau:
a, muab cov vulcanizing tus neeg sawv cev sib npaug rau hauv cov roj hmab compounding, thiab tsis txhob mloog zoo rau hauv ib qho chaw.
b, muab qhov ceev tsis tuaj yeem ceev heev. Casting ceev, tus neeg sawv cev vulcanizing yog ib qho yooj yim rau poob mus rau hauv qab, thiab tsis yooj yim rau disperse mus rau compounding roj hmab nyob rau hauv, uas yuav cuam tshuam rau kev ua tau zoo ntawm compounding roj hmab.
c, poob rau lub nruas hauv qab tus neeg sawv cev vulcanizing thiab muab tso rau hauv cov roj hmab compounding.
3, thiab yog li tsis tuaj yeem pom tus neeg sawv cev vulcanizing nrog rau cov vulcanization accelerator tom qab pib txiav, sab laug thiab sab xis ob zaug txhua. Kom cia tus neeg sawv cev vulcanizing thiab vulcanization accelerator zoo dua dispersed rau cov roj hmab sib tov, tuaj yeem paub tseeb los ntawm kev soj ntsuam daim ntawv ntawm tus neeg sawv cev vulcanizing thiab cov vulcanization accelerator: yog tias nws yog ib qho khoom rau hauv cov nplaum lo lo ntxhuav, thiab tom qab ntawd sib xyaw rau hauv cov roj hmab, yog li ntawd. cov nyhuv sib xyaw yog qhov zoo.
4, Tshem tawm cov roj hmab sib xyaw kom nyias dhau. Thaum nyias dhau lawm, qhov qhib sib tov zeb qhov yob nrug yuav tsum tau kho kom tsawg; tus naj npawb ntawm nyias hla hauv 4 ~ 5 zaug.
Tawm ntawm daim ntawv yuav tsum ua raws li cov thickness xav tau los ntawm cov khoom molding. Tag nrho cov txheej txheem yuav tsum tau muab sau tseg tias lub sijhawm ua tiav tsis ntev dhau los, txwv tsis pub nws yuav txo qis Menny viscosity thiab lub cev lub cev.
