UV hluav taws xob muab cov pob zeb polymer, ua rau kom nto sab tawg thiab brittleness. Ozone, cov pa roj cua sov heev, tawm tsam cov khoom sib tsoo ob npaug hauv cov roj hmab, ua rau cov kab nrib pleb kom tawg. Kev kub siab tuaj yeem ua rau cov teebmeem no los ntawm kev nce tus nqi ntawm cov tshuaj lom neeg. Txhawm rau tawm tsam cov kev sib tw no, cov chaw tsim khoom feem ntau ua rau cov cab stabilizers thiab antioxidant rau cov roj hmab.
Mechanical kev ntxhov siab
Kev ntxhov siab; suav nrog kev ncab, nrog kev ncab, compression, thiab puas (pab rau kev laus ntawm cov roj hmab. Rov ua dua kev ntxhov siab mus yuav ua rau muaj kev qaug zog, ua rau micro-tawg thiab teeb meem tsis ua tiav. Kev ntxhov siab ntawm kev ntxhov siab thiab ib puag ncig muaj tseeb, xws li ozone kis tau, ntxiv nrawm nrawm nrawm. Cov kws tsim khoom lag luam yuav tsum xav txog cov xwm txheej no thaum tsim cov khoom siv roj hmab rau cov ntawv thov, xws li cov log tsheb thiab cov ntsaws ruaj ruaj.
Cov tswv yim kom txo cov roj hmab laus
Cov khoom siv xaiv
Xaiv txoj cai hom roj hmab yog qhov tseem ceeb rau kev txo txiaj ntsig kev kub ntxhov. Synthetic Rubbers, xws li Ethylene Propylene diene Monomer (EPDM) thiab fluoroelastomers, muaj cov tshuaj fluoroelastomers, muaj cov roj hmab zoo tshaj plaws piv rau cov roj hmab ntuj. Cov ntaub ntawv no feem ntau siv rau hauv cov ntawv thov cov kev xav tau siab thiab cov tshuaj tiv thaiv. Yog xav paub ntxiv txog EPDM cov versatility, tshawb nrhiav Yas.
Ntxiv thiab stabilizers
Kev sib xyaw ua ke ntxiv thiab stabilizers rau hauv cov roj hmab tsim khoom tuaj yeem txhim kho kom dhau los ntawm kev laus. Antioxidants tiv thaiv oxidatizatizatizer dawb radicals, thaum UV Stabiilizers nqus cov teeb meem hluav taws xob hnyav. Fillers, xws li carbon dub thiab silica, txhim kho cov khoom siv cov khoom siv cov khoom siv thiab txo qhov kev cuam tshuam ntawm cov kev ntxhov siab ib puag ncig. Cov tshuaj ntxiv no tau txiav rau cov ntawv thov tshwj xeeb kom ua kom tau zoo thiab muaj peev xwm ua tau ntev.
Cov Khaub Ncaws Tiv Thaiv
Ua ntawv thov cov txheej txheem tiv thaiv yog lwm lub tswv yim zoo los txo cov roj hmab laus. Txheej txheem tawm tsam UV hluav taws xob, thiab tshuaj lom neeg, txuas ntxiv cov khoom siv nyiaj. Xws li cov txheej txheej silicone-ua piv txwv, tau siv dav hauv kev siv tsheb thiab cov ntawv thov ib lub tsev rau lawv cov huab cua zoo heev thiab kav ntev. Cov txheej txheej no yog cov muaj txiaj ntsig tshwj xeeb rau cov khoom siv roj hmab nthuav dav rau ib puag ncig hnyav.
