Cov khoom
Nontoxic, combustible, daj hmoov.Raws li nrog S-isomer, hais tias mu-sulfur, siab polymerization cov ntaub ntawv, tsis soluble nyob rau hauv carbon disulfide thiab lwm yam kuab tshuaj.Mu-sulfur instability yuav maj mam hloov mus rau hauv cubic crystal-sulfur, ob peb lub lis piam ntawm chav tsev kub 50% hloov, ntev li 80 ℃ nrog kev hloov nyob rau hauv ob peb feeb, qhov no yuav tsum tau los ntawm kev ntxiv stabilizer kom txo tau nws tus nqi ntawm kev hloov.
Daim ntawv thov
Insoluble sulfur feem ntau yog siv rau hauv kev lag luam roj hmab, vim tias cov tshuaj tua kab mob ua rau cov roj hmab saum npoo pleev xim, uas yuav txhim kho cov hlau-nplaum khi, vim tias cov yas sib txawv, uas yuav ua kom zoo ntawm vulcanization, yog cov roj hmab zoo tshaj plaws, nws yog dav siv log tsheb carcass compound, tshwj xeeb tshaj yog meridian log tsheb tag nrho cov hlau, kuj siv tau rau cable, cots, roj hmab khoom xws li roj hmab compound.
Pob
25kg kraft ntawv hnab.
Cia
Cov khoom yuav tsum tau muab cia rau hauv qhov chaw qhuav thiab txias nrog qhov cua zoo, tsis txhob raug cov khoom ntim rau hauv tshav ntuj ncaj qha.Lub validity yog 1 xyoo.
Cov ntaub ntawv txuas ntxiv
Qhov zoo:
1) Insoluble sulfur muaj nyob rau hauv lub xeev dispersed nyob rau hauv cov roj hmab, kom ntseeg tau tias cov khoom siv roj hmab tsis tsuag Frost thiab muaj adhesion zoo, thaum ua kom zoo zoo ntawm lub teeb xim cov khoom.
2) Insoluble sulfur yog tusyees dispersed nyob rau hauv cov khoom siv roj hmab, zoo tiv thaiv cov aggregation ntawm leej faj thiab txo cov nyiam scorch thaum lub sij hawm cia ntawm cov khoom siv roj hmab.
3) Insoluble sulfur tiv thaiv Frost txau thaum lub sij hawm cia ntawm cov nplaum, tswj kev ua haujlwm zoo ntawm cov nplaum nplaum.Tiv thaiv kom tsis txhob muaj kab mob ntawm cov khoom thiab pwm, thiab tshem tawm cov txheej txheem txheej txheej ntxiv kom kov yeej Frost txau, muab cov xwm txheej rau kev sib txuas ntau lawm.
4) Insoluble sulfur tiv thaiv cov roj hmab los ntawm kev tsiv ntawm cov nplaum nplaum uas nyob ib sab.Tshwj xeeb tshaj yog nyob rau hauv cov tebchaw ntawm cis-1,4-butyl roj hmab thiab butadiene roj hmab, qhov kev tsiv teb tsaws ntawm cov sulfur zoo tib yam yog siab heev, uas tuaj yeem zam tau los ntawm kev ntxiv cov sulfur insoluble.
5) Insoluble sulfur shortens lub sij hawm vulcanization.Tom qab ncav cuag qhov kub ntawm vulcanization, nws muaj "kev ua haujlwm theem", uas yog cov saw depolymerization, uas ua rau lub vulcanization tus nqi thiab txo cov leej faj siv, uas yog qhov zoo rau kev txhim kho kev laus ntawm cov khoom.
