Cov khoom siv roj hmab yog ua raws li cov roj hmab nyoos thiab ntxiv nrog cov nqi tsim nyog ntawm cov khoom sib xyaw ua ke.…
1.Ntuj los yog hluavtaws roj hmab uas tsis muaj cov tshuaj compounding los yog tsis muaj vulcanization yog collectively hu ua roj hmab raw.Cov roj hmab ntuj muaj cov khoom zoo, tab sis nws cov khoom tso 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 xav tau tshwj xeeb, yog li muaj ntau daim ntawv thov ntawm cov roj hmab hluavtaws.…
Compounding tus neeg saib xyuas txhawm rau txhim kho thiab txhim kho ntau yam khoom ntawm cov khoom siv roj hmab, cov tshuaj ntxiv yog hu ua compounding agent.Cov tshuaj sib xyaw ua ke feem ntau suav nrog vulcanization pos, fillers, vulcanization accelerators, plasticizers, anti-aging agents thiab foaming agents.
① Lub luag haujlwm ntawm vulcanizing tus neeg sawv cev zoo ib yam li tus neeg sawv cev kho hauv cov thermosetting plastics.Nws ua rau cov roj hmab molecular chains tsim kab rov tav chains, tsim nyog cross-linked, thiab ua ib lub network qauv, yog li txhim kho cov neeg kho tshuab thiab lub cev ntawm cov roj hmab.Feem ntau siv sulfide yog sulfur thiab sulfide.…
② Cov muab tub lim yog los txhim kho cov khoom siv ntawm cov roj hmab, xws li lub zog, hardness, hnav tsis kam thiab rigidity.Feem ntau siv cov fillers yog carbon dub thiab textiles, fibers, thiab txawm hlau hlau los yog hlau braids raws li lub moj khaum cov ntaub ntawv.Ntxiv cov fillers tuaj yeem txo cov roj hmab nyoos thiab txo tus nqi roj hmab.…
③ Lwm cov tshuaj sib xyaw ua ke vulcanization accelerators tuaj yeem ua kom cov txheej txheem vulcanization thiab txhim kho cov nyhuv vulcanization;plasticizers yog siv los ua kom cov roj hmab plasticity thiab txhim kho cov txheej txheem molding;antioxidants (antioxidants) yog siv los tiv thaiv lossis ncua kev laus ntawm cov roj hmab.
2.Nta thiab kev siv ntawm cov khoom siv roj hmab
Cov khoom siv roj hmab muaj cov yam ntxwv ntawm siab elasticity, siab resilience, siab zog thiab siab hnav tsis kam.Nws elastic modulus yog tsawg heev, tsuas yog 1-10 MPa, thiab nws elastic deformation loj heev, mus txog 100% mus rau 1000%.Nws muaj qhov yooj yooj yim thiab lub zog cia muaj peev xwm.Tsis tas li ntawd, nws muaj kev hnav zoo, suab rwb thaiv tsev, damping thiab rwb thaiv tsev.Txawm li cas los xij, roj hmab tsis muaj cua sov tsis zoo thiab ua haujlwm txias (nplaum ntawm qhov kub thiab txias, nkig thaum raug txias), thiab yuav yaj hauv cov kuab tshuaj.…
Hauv kev lag luam, roj hmab tuaj yeem siv los ua cov log tsheb, zoo li qub thiab dynamic seals, vibration damping thiab anti-vibration qhov chaw, kis tau tus mob siv, conveyor siv thiab kav, xov hlau, cables, hluav taws xob rwb thaiv tsev cov ntaub ntawv thiab nres qhov chaw.
