I. Lub luag haujlwm ntawm zinc oxide hauv vulcanization ntawm fluoroelomer
1. Kev ua kom muaj qhov tshuaj tiv thaiv vulcanization
Zinc oxide cov haujlwm ua haujlwm ua haujlwm hauv lub cev ua kom muaj fluoroelastomer. Nws tuaj yeem cuam tshuam nrog vulcanizing tus neeg sawv cev thiab tus tsuj roj kom tsim cov nyom, yog li txhim kho cov tshuaj tiv thaiv tus nqi ntawm vertolanization. Piv txwv li, hauv peroxide- molcanized fluoroofer system, uas yog qhov tseem ceeb rau kev tsim ntawm ib tug qauv ntawm cov qauv network.
2. Muaj kev cuam tshuam ntawm tus ntoo khaub lig -} kev txuas ntom ntom ntom ntom
Tus nqi ntawm zinc oxide ntxiv cuam tshuam rau cov ntoo khaub lig-} ntawv txuas ntawm fluoroelastomer. Tsim nyog ntxiv ntawm zinc oxide tuaj yeem nce tus ntoo khaub lig- Cov roj hmab cov roj hmab, xws li lub zog ntawm cov roj hmab, xws li lub zog tensile, rhuav lub zog, thiab lub zog. Txawm li cas los xij, ntau dhau los zinc oxide yuav ua rau ib tug overly high cross-} hack thiab txo nws cov roj hmab tawg thiab txo nws txoj kev elongation thiab hloov tau.
3. Kev Cuam Tshuam Rau Vulcanization Kinetics
Zinc oxide cuam tshuam lub vulcanization kinetics ntawm fluoroelomastomer. Los ntawm kev hloov pauv lub zog ntawm cov tshuaj tiv thaiv vulcanization, nws tuaj yeem ua kom nrawm lossis rov qab ua kom cov txheej txheem vulcanization. Hauv qee kis, ib qho nyiaj kom raug ntawm zinc oxide tuaj yeem ua kom txoj kev sib raug zoo uas tau muaj kev sib raug zoo.
Ii. Yam cuam tshuam rau kev cuam tshuam ntawm zinc oXide ntawm Fluoroelastomer Vulcanization
1. Particle loj ntawm zinc oxide
Lub particle loj ntawm zinc oxide muaj feem cuam tshuam rau nws txoj haujlwm hauv cov txheej txheem vulcanization. Me dua -} qhov chaw dhuav dic oxide loj, uas tuaj yeem txhim kho lawv cov kev sib txawv ntawm cov khoom siv roj hmab. Qhov no ua rau muaj kev ua kom muaj txiaj ntsig ntau dua ntawm cov tshuaj tiv thaiv vulcanization thiab kev faib tawm ntau dua ntawm tus ntoo khaub lig cov khoom siv ntawm vulcanized fluoroelium.
2. Hom vulcanization system
Txawv cov tshuab ua kom sib txawv rau fluoroelomer, xws li peroxide {}} Nyob rau, lossis bis} Nyob nrog zinc oxide hauv qhov sib txawv. Piv txwv li, hauv peroxide - pulcanized system, nws tuaj yeem koom nrog kev siv tshuaj tua kab mob zoo sib xws, cuam tshuam cov khoom siv vulcanization thiab cov khoom siv kawg ntawm cov roj hmab.
3. Cov mis tag nrho cov fluoroelomer
Lub xub ntiag ntawm lwm yam khoom xyaw hauv fluoroelastomer fluoroelastomer fluoroelastomer, cov yas, thiab cov tshuaj tua kab mob, tuaj yeem cuam tshuam nrog zinc oxide thiab cuam tshuam nws txoj haujlwm hauv vulcanization. Fillers yuav adsorb zinc oxide, txo nws cov kev xav tau zoo rau cov tshuaj tiv thaiv vulcanization. Cov tshuab yas, ntawm qhov tod tes, tuaj yeem hloov qhov kev mus ncig ntawm cov roj hmab lwg me me, uas nyob rau hauv cov diffusion ntawm zinc oxide thiab lwm yam reactant thaum lub sij hawm vulcanization.
III. Cov tswv yim zoo rau kev siv zinc oxide hauv fluoroelastomer vulcanization
1. Kev tswj hwm ntawm zinc oxide noj

Qhov no tuaj yeem ua tiav los ntawm kev tshawb fawb ntawm viansization cov khoom siv thiab kev nkag siab cov yam ntxwv, thiab kev sib tw tiv thaiv ntawm cov vulcanizates. Piv txwv li, hauv cov tshuaj fluoroelastomer tshwj xeeb rau cov khoom siv hauv tsheb, cov tshuaj lom zem zoo nkauj.
2. Xaiv cov hom zinc oxide tsim nyog
Xav txog qhov loj me me, particle, thiab nto kev kho mob ntawm zinc oxide, xaiv qhov hom tsim nyog tshaj plaws rau kev thov fluoroelastomer yog qhov tseem ceeb. Nano {{{{- qhov chaw xaiv thaj chaw thiab muaj peev xwm txhim kho cov tshuaj tiv thaiv kab mob fluoroel fluorastomer, raws li nws tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov roj hmab vulcanized.
3. Synergistic optimization nrog lwm cov khoom sib ntxiv
Txhawm rau ua kom zoo dua tus txheej txheem vulcanization ntawm fluorooelomer, Zinc Oxide tuaj yeem siv ua ke nrog lwm cov kev sib ntxiv hauv kev sib ntxiv. For example, combining zinc oxide with a specific accelerator can enhance the vulcanization rate and improve the cross-linking structure. Ib qho ntxiv, ntxiv rau qee qhov kev sib txuas lus tuaj yeem txhim kho kev sib cuam tshuam ntawm zinc oxide thiab txhim kho nws cov hauj lwm zoo hauv kev ua kom zoo nkauj.
IV. Tag
Zinc Oxide ua si lub luag haujlwm tsis tseem ceeb hauv kev ua kom lub ntsej muag fluoroelastomer. Los ntawm kev nkag siab txog nws cov kev tiv thaiv kev cuam tshuam, peb tuaj yeem txhim kho cov kev ua kom zoo, thiab ua tau zoo dua nws cov kev ua tau zoo, thiab ua tau raws li cov kev xav tau tsim nyog ntawm cov ntawv thov niaj hnub no. Nyob rau hauv yav tom ntej kev tshawb fawb thiab kev loj hlob, yuav tsum ua kom tshawb nrhiav kev tswj hwm ntau dua thiab ua kom zoo dua kev siv fluoroelastomer volcanization.
