Cov roj hmab hauv pem teb tau siv rau hauv kev lag luam rau ntau tshaj 100 xyoo, feem ntau yog ua los ntawm kev kub vulcanization (feem ntau los ntawm txoj kev vulcanization tank) cov roj hmab tawv thiab semi-hard los txhim kho nws txoj kev tiv thaiv corrosion thiab kev sib txuas ua ke. Nrog rau kev txhim kho cov ntaub ntawv polymer, ntau yam roj hmab hluavtaws thiab lwm yam khoom siv tau maj mam nkag mus rau hauv cov roj hmab hauv pem teb, ua rau lawv tiv taus acid, alkali, roj, cua sov, kev cuam tshuam, thiab elastic heev.
Hom roj hmab twg siv ua cov ntaub sab hauv?
Ob hom roj hmab tseem ceeb feem ntau siv ua cov ntaub ntawv hauv ob sab: roj hmab ntuj thiab roj hmab hluavtaws
Roj Hmab Ntuj:Feem ntau cov roj hmab ntuj tsim muaj ntau hom roj hmab polyethylene. Cov roj hmab no muaj cov yam ntxwv tsis tawv, muaj zog, yooj ywm thiab muaj peev xwm nqus thiab tiv thaiv cov teeb meem xeb ntawm cov khoom uas lawv tuav.
Khoom siv hluavtawsRubber:Cov roj hmab hluavtaws xws li butyl, hypalon, neoprene thiab nitrile muaj kev tiv thaiv zoo rau cov hydrocarbons thiab cov roj av.
Ob hom roj hmab muaj qhov zoo thiab qhov tsis zoo, yog li hom siv ua cov khoom siv hauv pem teb yuav nyob ntawm qhov xav tau tshwj xeeb ntawm daim ntawv thov.
Hauv qee qhov kev siv, kev hnav thiab xeb yog cov teeb meem uas feem ntau ua rau cov khoom siv tsis ua haujlwm, lub sijhawm tsis ua haujlwm thiab kev kho kim heev. Cov roj hmab zoo heev tuaj yeem muab kev tiv thaiv zoo, ua kom lub neej ua haujlwm ntev dua thiab txo cov nqi txij nkawm. Ntau lub lag luam xav tau cov roj hmab ruaj khov thiab tawv kom kov yeej cov xwm txheej ua haujlwm hnyav, thiab kev tiv thaiv kev sib txhuam yog qhov tseem ceeb uas yuav tsum xav txog thaum ntsuas cov kev xaiv tiv thaiv cov khoom siv. Cov roj hmab hauv pem teb hais txog kev siv cov roj hmab uas tiv taus kev hnav, tiv thaiv kev xeb thiab tiv taus kub siab ua cov ntaub hauv pem teb sab hauv cov khoom siv lossis cov kav dej.Cov khoom siv lub cev thiab tshuaj ntawm cov roj hmab nws tus kheej txo qhov cuam tshuam ntawm cov khoom siv thauj los ntawm cov khoom siv rau nws cov qauv.
Los ntawm kev kho cov khoom siv thiab cov txheej txheem tsim khoom ntawm cov yeeb nkab, peb tuaj yeem kho kom haumlubcov yeeb nkab rau cov kev xav tau tshwj xeeb thiab cov xwm txheej ib puag ncig ntawm daim ntawv thov, kev sim thiab kev sim tseem ceeb kuj tau ua kom ntseeg tau tias cov yeeb nkab kho kom haum tuaj yeem ua tau raws li cov kev xav tau ntawm daim ntawv thov thiab muaj kev ua tau zoo. Raws li lub tuam txhab tshwj xeeb hauv kev tsim qauv thiab tsim cov yeeb nkab roj hmab, CDSR cog lus tias yuav muab cov yeeb nkab roj hmab zoo thiab cov kev daws teeb meem tshwj xeeb rau cov neeg siv khoom.
