Silicone roj hmab yog cov khoom siv ntau yam uas tau siv dav hauv kev tsim khoom ntawm ntau yam khoom hauv kev lag luam sib txawv.Nws cov khoom tshwj xeeb ntawm elasticity, durability thiab tsis kam mus rau huab cua kub ua rau nws zoo tagnrho rau ntau yam kev siv.Thaum nws los txog rau silicone roj hmab, muaj ob lub ntsiab: khoom silicone thiab kua silicone.Txhua hom muaj nws tus yam ntxwv thiab qhov zoo thiab tsim nyog rau ntau lub hom phiaj.
Cov khoom siv silicone, raws li lub npe qhia, yog cov khoom siv molded thiab kho rau hauv cov duab uas xav tau.Nws yog tsim los ntawm kev sib tov silicone elastomers nrog catalysts thiab lwm yam additives, ces molded los yog extruded rau hauv cov duab xav tau.Khoom silicone paub txog nws lub zog tsim kua muag, zoo heev tensile lub zog thiab tsis kam mus compression txheej.Cov khoom zoo no ua rau nws tsim nyog rau cov ntawv thov uas xav tau cov khoom siv ruaj khov thiab kav ntev.
Ib qho ntawm cov kev lag luam tseem ceeb uas tau txais txiaj ntsig los ntawm cov khoom siv silicone yog kev lag luam tsheb.Automotive khoomxws ligaskets, seals thiab O-ringsfeem ntau yog tsim los ntawm cov khoom siv silicone vim tias nws muaj peev xwm tiv taus qhov kub thiab txias ib puag ncig.Cov khoom no ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ua haujlwm zoo thiab kev ntseeg siab ntawm ntau lub tshuab tsheb.Cov khoom siv silicone gaskets thiab cov ntsaws ruaj ruaj zoo tiv thaiv cov kua, roj thiab lwm yam khoom paug, tiv thaiv kev xau thiab ua kom muaj kev ua tau zoo.
Ntxiv nrog rau cov khoom siv tsheb, cov khoom siv silicone yog dav siv hauv kev lag luam kho mob.Nws biocompatibility, tiv thaiv kab mob thiab lwm yam kab mob, thiab muaj peev xwm tiv taus cov txheej txheem ua kom tsis muaj menyuam ua rau nws yog cov khoom siv zoo tshaj plaws raucov khoom kho mob. Cov cuab yeej kho mob, implants thiab prosthetics feem ntau muaj cov khoom siv silicone kom ntseeg tau tias cov neeg mob muaj kev nyab xeeb, kev ua neej ntev thiab kev nplij siab.Tsis tas li ntawd, khov khosilicone keyboard nyees khawmfeem ntau yog siv rau hauv cov khoom siv kho mob vim lawv zoo heev puas.
Ntawm qhov tod tes, muaj pes tsawg leeg thiab kev tsim cov txheej txheem ntawm cov kua silicone sib txawv.Liquid silica gel yog cov khoom siv ob feem uas muaj cov kua matrix thiab cov catalyst.Tsis zoo li cov khoom siv silicone, uas kho tau los ntawm cov cua sov lossis cov tshuaj tiv thaiv, cov kua silicone kho los ntawm cov txheej txheem tshwj xeeb txhaj tshuaj molding.Cov txheej txheem ua rau cov kua silicone ntws thiab sau cov pwm nyuaj, ua kom cov khoom tsim tau zoo thiab cov ncauj lus kom ntxaws.
Cov kua silicone muaj qhov tshwj xeeb zoo ntawm kev tsim khoom thiab kev tsim qauv yooj yim.Nws cov viscosity tsawg ua rau nws yooj yim los sau pwm, thiab nws lub sijhawm kho luv luv ua rau nws tsim nyog rau cov khoom ntim siab.Cov cuab yeej no tau ua kua silicone nce nrov hauv kev lag luam xws li hluav taws xob,cov khoom sivthiabcov khoom me nyuamuas feem ntau yuav tsum tau complex thiab ilv designs.Tsis tas li ntawd, qhov siab precision thiab sib xws ntawm cov kua silicone molding tuaj yeem ua tiav nruj kam rau ua thiab cov duab nyuaj.
Ua kom tiav, ob qho tib si silica gel thiab kua silica gel muaj lawv tus kheej zoo thiab daim ntawv thov teb.Cov khoom siv silicone yog nyiam nyob rau hauv kev lag luam uas muaj zog, elasticity thiab tsis kam mus rau huab cua yog qhov tseem ceeb, xws li tsheb thiab khoom kho mob.Liquid silicone, ntawm qhov tod tes, yog qhov zoo tagnrho rau kev lag luam uas xav tau cov khoom lag luam siab, cov qauv tsim, thiab nruj kam rau ua.Xaiv hom silicone kom raug rau ib daim ntawv thov tshwj xeeb yuav tsum tau ua tib zoo xav txog cov khoom xav tau, ib puag ncig yam thiab cov yam ntxwv xav tau.
