Cov khoom siv roj hmab yog ua los ntawm cov roj hmab nyoos thiab ntxiv nrog cov tshuaj sib xyaw kom haum. …
1.Cov roj hmab ntuj lossis cov roj hmab tsim uas tsis muaj cov tshuaj sib xyaw lossis tsis muaj vulcanization yog hu ua roj hmab nyoos. Cov roj hmab ntuj muaj cov yam ntxwv zoo, tab sis nws cov khoom tsim tawm tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev lag luam, thiab nws tsis tuaj yeem ua tau raws li qee qhov kev ua tau zoo tshwj xeeb, yog li muaj ntau daim ntawv thov ntawm cov roj hmab tsim. …
Cov neeg sawv cev sib xyaw Txhawm rau txhim kho thiab txhim kho ntau yam khoom ntawm cov khoom roj hmab, cov tshuaj ntxiv hu ua tus neeg sawv cev sib xyaw. Cov neeg sawv cev sib xyaw feem ntau suav nrog cov pos hniav vulcanization, cov khoom sau, cov khoom ua kom nrawm vulcanization, cov khoom ua kom yas, cov neeg sawv cev tiv thaiv kev laus thiab cov neeg sawv cev ua npuas dej.
① Lub luag haujlwm ntawm tus neeg sawv cev vulcanizing zoo ib yam li tus neeg sawv cev kho hauv cov yas thermosetting. Nws ua rau cov saw hlau roj hmab tsim cov saw kab rov tav, sib txuas ua ke, thiab dhau los ua cov qauv network, yog li txhim kho cov khoom siv kho tshuab thiab lub cev ntawm cov roj hmab. Cov sulfide feem ntau siv yog sulfur thiab sulfide. …
② Cov khoom sau yog los txhim kho cov khoom siv kho tshuab ntawm roj hmab, xws li lub zog, qhov nyuaj, kev tiv thaiv hnav thiab kev nruj. Cov khoom sau feem ntau siv yog cov pa roj carbon dub thiab cov ntaub, cov fibers, thiab txawm tias cov hlau xaim lossis cov hlau braids ua cov ntaub ntawv tsim kho. Ntxiv cov khoom sau kuj tseem tuaj yeem txo cov roj hmab nyoos thiab txo cov nqi roj hmab. …
③ Lwm cov neeg sawv cev sib xyaw ua ke vulcanization accelerators tuaj yeem ua kom cov txheej txheem vulcanization sai dua thiab txhim kho cov nyhuv vulcanization; cov yas yas yog siv los ua kom cov roj hmab plasticity thiab txhim kho cov txheej txheem molding; cov tshuaj antioxidants (antioxidants) yog siv los tiv thaiv lossis ncua cov roj hmab laus.
2.Cov yam ntxwv thiab daim ntawv thov ntawm cov khoom siv roj hmab
Cov khoom roj hmab muaj cov yam ntxwv ntawm kev ywj pheej siab, kev ywj pheej siab, lub zog siab thiab kev tiv thaiv kev hnav siab. Nws cov modulus elastic qis heev, tsuas yog 1-10 MPa, thiab nws cov deformation elastic loj heev, txog li 100% txog 1000%. Nws muaj kev ywj pheej zoo heev thiab muaj peev xwm khaws cia lub zog. Tsis tas li ntawd, nws muaj kev tiv thaiv kev hnav zoo, kev rwb thaiv suab, kev damping thiab kev rwb thaiv tsev. Txawm li cas los xij, roj hmab muaj kev tiv thaiv cua sov thiab kev tiv thaiv txias tsis zoo (nplaum ntawm qhov kub siab, brittle thaum raug rau txias), thiab yuav yaj hauv cov kuab tshuaj. …
Hauv kev lag luam, roj hmab siv tau los ua cov log tsheb, cov foob pob hluav taws xob thiab cov khoom siv dynamic, cov khoom siv tiv thaiv kev co thiab kev tiv thaiv kev co, cov siv txoj siv sib kis, cov siv txoj siv conveyor thiab cov kav dej, cov xov hlau, cov cables, cov ntaub ntawv rwb thaiv hluav taws xob thiab cov khoom siv nres.
