Zinc oxide yog cov neeg sawv cev nquag siv hauv roj hmab ua. Nyob rau hauv cov roj hmab ntau lawm, khib nyiab thiab kev rov ua dua tshiab yuav tso cov duab zinc sib xyaw, ua rau muaj kev phom sij rau ib puag ncig, yog li tus nqi ntawm cov hnab roj hmab yuav tsum tau txo. active zinc oxide muaj qhov me me me me, thaj chaw loj, piv nrog txo cov kev phom sij rau ib puag ncig, xav txog cov txiaj ntsig ib puag ncig thiab nyiaj txiag ib puag ncig.
Ib qho Cursive zinc oxide yog tsim kev siv cov txheej txheem ntub dej, kev sib xyaw ua ke nrog cov pa oxide thiab pob tshab rau cov txheej txheem kev hloov kho tsis ncaj ncees los ntawm ntau lwm cov neeg tsim khoom. Cov txheej txheem ntub dej muaj qib siab ntawm cov txheej txheem zoo sib xws, cov txheej txheem ntawm cov ntawv sau tshwj xeeb rau cov khoom siv hnyav, thiab cov ntsiab lus tsawg dua ntawm cov khoom lag luam hlau hnyav
Cov txheej txheem ntau lawm ntawm cov txheej txheem ntub dej yog raws li hauv qab no: Zinc Inging thiab tom qab ntawd nws cov tshuaj tiv thaiv nrog cov khoom siv zincbonate raws li cov khoom siv raw rau zinc oxide. Nrog zinc carbonate li cov khoom siv raw, zinc oxide yog tsim los ntawm kev ntxuav, kom qhuav, calcining thiab crushing.
Qhov nruab nrab particle loj ntawm active zinc oxide yog 50nm, thaj chaw tshwj xeeb yog honeyomb, xoob thiab ntxeem tau, yog li kev faib tawm yog qhov zoo; Nws diffusion ceev yog nrawm dua li cov kev sib tw zinc oxide, hauv cov tshuaj tiv thaiv no los txhim kho cov kev sib tw ntawm cov hniav kub, ib txwm tuaj yeem ua rau pom tag nrho; Cov Hnyhav cov hlau PB2 +, Cu2 +, CN2 +, MN2 +, FE2 + cov ntsiab lus yog tsawg heev, hauv txoj cai ntawm kev tiv thaiv ib puag ncig.
Kev siv khoom
Zinc Oxide hauv cov roj hmab kev lag luam feem ntau yog siv los ua cov tshuaj tua roj hmab (cov haujlwm nrawm) Nws cov kev tawm tsam yog: zinc oxide thiab cov tshuaj tiv thaiv ceev cov tshuaj tiv thaiv los tsim cov nrawm zinc ntsev; accelerator zinc ntsev thiab polysulfide molecules los tsim cov polysulfide zinc ntsev; Cov roj hmab polromolecule thiab roj hmab tsis muaj zog, ua kom muaj kev nyab xeeb rau cov roj hmab uas tsis muaj zog, thiab nce cov txiaj ntsig ntawm roj hmab vulcanization. Thiab txhim kho cov roj hmab vulcanized ncab kev ntxhov siab, tensile lub zog thiab elongation, txo cov compression deformation, thiab lwm yam.
1. Active zinc oxide nyob rau hauv lub semi-steel Radial Tyre Innerliner Thov
Nyob rau hauv tib tus nqi ntawm cov xwm txheej, kev siv cov active zinc oxide tshuab kho kom zoo dua li siv ntawm dinc ox oxide 1 # cov roj hmab tau nce txog 1 zaug; 3 # Formula ntawm cov dej ntws nquag zinc 3 kev tsim txiaj ntawm cov khoom siv roj hmab Choking, tus menni viscosity tsis ntau qhov sib txawv.
Ntsuas cov tshuaj txhuam cov roj hmab nyuaj, theem tensile, qib siab ua tau zoo dua thiab kua muag ua kom sov thiab cua ua kom sov qis dua me ntsis.
active zinc oxide hloov ntawm zinc oxide me me thiab siv roj hmab radial, kho roj hmab radial cov roj hmab, uas yog qhov ua kom luv rau luv luv lub sij hawm. Kev siv cov active zinc oxide tuaj yeem txo cov nqi ntawm zinc oxide, ntau dua rau cov kev xav tau ntawm kev tiv thaiv ib puag ncig.
2. Daim ntawv thov ntawm active zinc oxide hauv cov log radial
Nrog rau kev nce hauv tus nqi ntawm active zinc oxide, tc10 thiab tc90 tag nrho cov txheej txheem ntawm kev loj hlob. ML thiab MH tsis hloov pauv ntau. Qhov no txhais tau tias cov nquag zinc oxide tuaj yeem siv rau hauv cov nyiaj txo qis.
Lub zog tensile, 100% elongation, 300% elongation thiab rhuav lub zog tsis hloov nrog qhov nce ntawm cov nquag zinc oxide. Thaum cov tshuaj ntau tshaj 5 ntu, kua muag lub zog ntawm cov roj hmab vulcanized cov roj hmab txo tau tshaj plaws ead, uas yog tshwm sim los ntawm ntau ntau ntawm cov nqi hla dhau. Tom qab kev laus ntawm 100 ℃ × × 24h, kev ua yeeb yam khaws cia ntawm cov roj hmab sib txuas nrog 3 ntu ntawm active zinc oxide yog qhov zoo tshaj plaws, thiab nrog 2.5 feem ntawm kev haus phem. Qhov laj thawj yuav yog qhov ntau ntawm 2.5 qhov, tus qauv virochized lub kua muag, uas tseem muaj kev tiv thaiv lub kua muag, dej nyab nyuaj, thiab compression hardation ua tau zoo.
Ntxiv rau cov nquag zinc oxide roj hmab sib tov, nws lub zog ntev, 100% torque-excoment qeeb, 100% lub zog ceev tau txhim kho, 100 ℃ × × 24h kev laus, cov hnoos qeev Cov yam ntxwv ntawm tus nqi rov ua dua tshiab tom qab kev laus ntawm 100 ℃ × × × × × × 24h, tus nqi khaws cia ntawm kev ua haujlwm tau zoo dua. Thaum cov nquag zinc oxide yog siv nyob rau hauv txo qis, tc90 - TS1 cov khoom siv tsis tseem ceeb, thiab cov tshuab roj hmab hloov pauv tsis pom tseeb; 2.5 qhov seem ntawm kev siv tshuaj, kev laus tsis kam ntawm cov roj hmab vulcanized cov roj hmab txo qis, yog li cov nyiaj tuaj yeem txo mus rau 3 ntu ntawm kev siv tshuaj.
Qhov Zoo ntawm Zinc Oxide
Los ntawm cov ntaub ntawv sim ntawm cov khoom saum toj no, nws tuaj yeem kawm tau tias cov nquag zinc oxide tuaj yeem siv dav hauv ntau cov khoom siv roj hmab.
(1) Nws muaj kev tawg ua kom zoo nyob rau hauv cov khoom siv roj hmab, thiab cov khoom siv cev nqaij daim tawv thiab cov kws kho tshuab tau txhim kho;
(2) hauv cov txheej txheem vulcanization. Lub sij hawm Coking ntawm cov roj hmab khoom siv dhau los ua ntev ntev, kev nyab xeeb ntawm vulcanization tau txhim kho, thiab ua tau zoo ntawm vulcanization yog txhim kho;
(3) Vim yog thaj chaw loj thiab thaj chaw me me ntawm cov nquag zinc oxide, nws tuaj yeem siv rau hauv cov roj hmab txo qis ntawm cov khoom siv roj hmab ntxiv.
