Zinc oxide yog cov tshuaj sib xyaw nrog cov qauv ZnO. Nws yog xyaum insoluble nyob rau hauv dej thiab soluble nyob rau hauv ob qho tib si acids thiab muaj zog bases. Zinc oxide yog ib qho tseem ceeb inorganic additive siv dav hauv cov khoom siv roj hmab. ZnO yog siv rau kev tsim cov roj hmab / hluavtaws roj hmab & latex hauv Rubber lossis Cable Industries. Nws yog siv nyob rau hauv cov ntaub ntawv no raws li ib tug vulcanizing active tus neeg saib xyuas, ntxiv zog tus neeg saib xyuas raws li ib tug colouring tus neeg saib xyuas kom cov roj hmab muaj corrosive kuj, tsim kua muag kuj & elasticity. Nws kuj yog siv los ua cov xim pleev xim thiab muab tub lim rau Dawb Roj Hmab, ua tus neeg sawv cev vulcanizing rau Neoprene Rubber, thiab ua lub teeb stabilizer rau cov khoom zoo-polded Plastics xws li polyolefins lossis PVC. Herchy Rubber muaj ntau yam kev xaiv ntawm zinc oxide qib kom tau raws li qhov xav tau sib txawvZinc oxide-ZnO

Zinc oxide yog ib qho inorganic khoom nrog cov tshuaj formula ZnO, ib qho oxide ntawm zinc. Nws yog insoluble hauv dej thiab soluble hauv acids thiab muaj zog hauv paus. Zinc oxide yog ib qho tshuaj ntxiv thiab siv dav hauv cov roj hmab hluavtaws.

ZnO yog siv los ua vulcanizing tus neeg sawv cev, tus neeg sawv cev txhawb zog thiab cov xim ntawm cov roj hmab ntuj, cov roj hmab hluavtaws thiab cov roj hmab hauv cov roj hmab lossis cable kev lag luam kev lag luam kom cov roj hmab muaj kev tiv thaiv corrosion, tsim kua muag thiab elasticity. Nws yog siv los ua tus neeg saib xyuas xim thiab muab cov roj hmab dawb, vulcanizing tus neeg sawv cev hauv cov roj hmab neoprene thiab lub teeb stabilizer ntawm cov yas xws li polyolefin lossis polyvinyl chloride rau cov khoom zoo (txog 0.1μm hauv qhov loj).

1. Cov log tsheb

Txhim kho cov thermal conductivity, hnav tsis kam, tsim kua muag, lub zog tensile thiab lwm yam kev ntsuas ntawm cov khoom, thiab tuaj yeem txuag tau li ntawm 30% ntawm zinc oxide.

2. Cov khoom siv roj hmab

①Activated zinc oxide feem ntau yog siv los ua tus neeg sawv cev ntawm cov roj hmab kom cov roj hmab muaj kev tiv thaiv corrosion, tsim kua muag thiab elasticity thiab elongation.

② Nws yog siv los ua cov txheej txheem ntawm cov roj hmab vulcanization thiab yog cov khoom siv roj hmab sib xyaw ua ke, feem ntau yog siv los ua vulcanization active tus neeg saib xyuas thiab txhawb tus neeg sawv cev ntawm cov roj hmab ntuj, hluavtaws roj hmab thiab latex.

③ Raws li vulcanization active neeg sawv cev, nws yog tusyees faib nyob rau hauv cov khoom siv roj hmab, muaj ib tug loj kev sib cuag cheeb tsam nrog hydrogen sulfide, thiab muaj ib tug ntau dua lub sij hawm los nqa tawm interfacial cov tshuaj tiv thaiv, ntxiv rau cov active zinc oxide khoom muaj kev pab los ntawm active tshuaj los catalyze hloov dua siab tshiab ntawm zinc oxide rau zinc sulfide.

④ Raws li sulfide oxidizer, nws txoj haujlwm yog txhawm rau txhim kho cov haujlwm ntawm accelerator, txo qhov ntau npaum li cas ntawm accelerator thiab txo lub voj voog vulcanization.

⑤ Nws tuaj yeem ua kom lub vulcanization ceev, txhim kho thermal conductivity ntawm vulcanized roj hmab, thiab ua kom lub vulcanization tiav.

⑥ Nyob rau hauv kev lag luam roj hmab, tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov pob tshab roj hmab cov khoom, active zinc oxide yog ib tug zoo heev vulcanizing active neeg sawv cev.

3. Synthetic roj hmab

Nws yog siv los ua activator, vulcanization accelerator thiab cov neeg sawv cev txhawb zog, thiab muaj cov xim xim. Txhawb lub vulcanization ntawm roj hmab, ua kom muaj zog thiab txhawb nqa, tiv thaiv kev laus, tuaj yeem ntxiv dag zog rau cov txheej txheem vulcanization, txhim kho lub kua muag thiab hnav tsis kam ntawm cov khoom siv roj hmab.
