Cov roj hmab silicone kua nplaum ntxiv-kho (ALSR) yog cov khoom siv polymeric ua tau zoo uas tau txais kev lees paub dav hauv ntau qhov chaw lag luam. Lub hauv paus, nws yog tsim los ua cov tshuaj nplaum zoo li, nrog rau vinyl-terminated polydimethylsiloxane ua lub hauv paus polymer, ua ke nrog cov neeg sawv cev tshwj xeeb thiab cov catalysts. Cov khoom sib xyaw tshwj xeeb no muab ALSR nrog cov khoom tshwj xeeb xws li kev ywj pheej zoo heev, kev ruaj khov thermal, thiab kev tiv thaiv tshuaj lom neeg, ua rau nws yog qhov kev xaiv zoo rau cov ntawv thov uas xav tau kev ua kom raug thiab kev ntseeg siab. Tsis zoo li lwm hom roj hmab silicone, cov txheej txheem kho ntawm ALSR ua tiav los ntawm kev sib xyaw ua ke, uas yog tus cwj pwm los ntawm kev shrinkage tsawg, tsis muaj cov khoom tso tawm, thiab muaj peev xwm kho tau ntawm ob qho tib si kub thiab siab, yog li txhim kho nws qhov kev hloov pauv hauv ntau qhov xwm txheej tsim khoom.
Kev faib tawm ntawm cov roj hmab silicone ntxiv-kho yog raws li ob qho tseem ceeb: hom khoom thiab kev ua tau zoo / daim ntawv thov. Los ntawm qhov kev xav ntawm hom khoom, nws tuaj yeem muab faib ua cov roj hmab silicone khov kho thiab cov roj hmab silicone kua. Ntawm lawv, cov roj hmab silicone kua, tshwj xeeb tshaj yog hom ntxiv-kho, sawv tawm rau nws cov kua ua ntej kho, uas tso cai rau nws kom yooj yim txhaj rau hauv cov pwm nyuaj, ua rau muaj kev tsim cov khoom sib xyaw thiab siab. Hais txog kev ua tau zoo thiab daim ntawv thov, ALSR tau muab faib ua hom dav dav thiab hom tsis kub. Lub hom phiaj dav dav ALSR ua tau raws li cov kev xav tau yooj yim ntawm feem ntau cov ntawv thov kev lag luam, xws li kev sib khi, kev sib txuas, thiab kev txhaj tshuaj, thaum ALSR tsis kub yog tsim tshwj xeeb los tswj nws qhov yooj ywm thiab cov khoom siv kho tshuab hauv qhov chaw kub qis, ua rau nws tsim nyog rau cov ntawv thov hauv aerospace, tsheb, thiab kev lag luam tub yees qhov twg qhov kub qis ruaj khov yog qhov tseem ceeb.
Muaj ntau hom roj hmab silicone uas kho tau zoo siv dav hauv kev tsim khoom lag luam, nrog rau dimethyl silicone roj hmab thiab methyl vinyl silicone roj hmab yog cov sawv cev tshaj plaws. Dimethyl silicone roj hmab, paub txog nws cov hluav taws xob rwb thaiv tsev zoo heev, tiv taus huab cua, thiab tshuaj lom neeg tsis muaj zog, tau siv dav hauv kev lag luam hluav taws xob thiab hluav taws xob rau kev tsim cov insulators, gaskets, thiab cov npog tiv thaiv. Methyl vinyl silicone roj hmab, ntawm qhov tod tes, muaj cov khoom siv vulcanization zoo dua thiab lub zog kho tshuab vim muaj kev qhia txog cov pawg vinyl, uas ua rau nws tsim nyog dua rau cov ntawv thov uas xav tau lub zog tensile siab dua thiab tiv taus kev tsim kua muag, xws li cov foob tsheb, cov khoom siv kho mob, thiab cov khoom siv hauv qib zaub mov. Nrog rau kev nce qib tas mus li ntawm kev siv tshuab hauv kev lag luam, qhov ntau thiab tsawg ntawm daim ntawv thov ntawm cov roj hmab silicone kua kho tau nthuav dav, thiab nws cov khoom sib xyaw ua ke yuav txuas ntxiv tsav kev tsim kho tshiab hauv ntau qhov chaw siv tshuab siab.
