Qhov sibtham hlawv hlawv, yog hais txog qhov sib ntxiv ntawm cov ntxhiab tsw ntxhiab hauv cov txheej txheem ntawm kev ua los yog chaw nres tsheb hauv qhov tshwm sim thaum ntxov, kuj muaj xws li los ntawm leej faj, nws qhov yog vulcanization, rubber ib nrab crosslinking.Tom qab hlawv, yog obviously txom nyem, los yog tsis tau ntws, tsis muaj kev ua tau.
Lub zog (fluidity) ntawm qhov tsawg kawg nkaus torque reactive kua nplaum thaum lub sij hawm coke hlawv sijhawm siab lossis tsis qis: Qhov ntev ntawm l ntawm lub sij hawm qhov coke hlawv qhia kev ruaj ntseg ntawm cov ntaub ntawv kua nplaum.
1. Ua rau coke hlawv
(1) txhawb txoj kev xaiv ntawm cov tsis tsim nyog;
(2) kev kub ntxhov siab dhau lawm;
(3) tsis txaus;
(4) lub sijhawm ua haujlwm ntev dhau lawm;
(5) tus neeg sawv cev ntawm tus neeg ua haujlwm tsis yog ib yam khoom siv.
2. Qhov cuam tshuam rau lub sijhawm muaj coking
(1) cov neeg txhawb nqa ntawm ntau yam: sulfonamides promoters char lub sijhawm yog ntev, thiuram hoob, dithiocarbamate promoters char lub sij hawm luv heev;
(2) kub: qhov siab dua qhov ntsuas kub los yog chaw nres tsheb qhov kub, qhov tshwm sim ntau rau coke phenomenon;
(3) lub sij hawm ua tiav: ntev lub sij hawm, qhov yooj yim dua burnt
(4) nrog rau tus neeg sawv cev: ZSJ nrog lub dispersing tus neeg sawv cev tsis yog cov tsoos tsho, cov koom haum pab pawg hauv zos yuav ua kom qhov kev ceev ceev ntawm lub zos qhov coke.
3. Ntsuas los tiv thaiv kev mob coke
(1) kev siv tardive promoters, xws li cov dej caw txhawb nqa sulfonamide.
(2) kev ntsuas kub, kev tswj ntawm tus thawj xibfwb feem ntau nyob rau hauv qhov cua sov ntawm 165 ℃, qhov siab tshaj tsis tshaj 180 ℃; H roj hmab qij kab kua nplaum feem ntau tsis tshaj 105 ℃, qhov siab tshaj tsis tshaj 110 ℃.
(3) txias ua ntej folding chaw nres tsheb, cia txias feem ntau nyob hauv 45 ℃, qhov siab tshaj tsis tshaj 50 ℃.
(4) nyob rau hauv cov ntaub ntawv ntawm dispersion kom paub meej tias tus neeg sawv cev, sim ua kom luv luv lub sij hawm ua.
(5) siv cov khoom siv tshuaj anticoking xws li CTP.
