Puas yog silicone muaj rau cov khoom yas?
Silica gel yog cov khoom siv colloidal ua los ntawm silicate, uas yog tsim los ntawm silica, dej thiab silicone monomers.Silica gel muaj cov yam ntxwv ntawm siab elasticity, siab transparency, siab stability thiab kub tsis kam, yog li nws yog dav siv nyob rau hauv ntau yam teb.Txawm hais tias silica gel zoo ib yam li cov yas hauv qee yam khoom, nws tsis yog cov khoom yas los ntawm qhov pom ntawm cov qauv tshuaj thiab cov txheej txheem kev npaj.
Ua ntej tshaj plaws, muaj qhov sib txawv pom tseeb hauv cov qauv tshuaj ntawm silicone thiab yas.Cov yas feem ntau yog tsim los ntawm cov khoom sib txuas siab molecular, uas tsim cov saw hlau ntev los ntawm polymerization, tsim cov qauv tsis tu ncua.Cov silica gel feem ntau yog tsim los ntawm silico-oxygen bonds, tsim ib lub network qauv.Cov qauv tshwj xeeb ntawm silico-oxygen daim ntawv cog lus ua rau silica gel muaj cov yam ntxwv ntawm cov ntaub ntawv nyuaj colloidal, thaum cov yas feem ntau yog cov khoom siv colloidal mos.
Qhov thib ob, kuj tseem muaj qhov sib txawv ntawm silica gel thiab yas hauv txheej txheem kev npaj.Kev npaj ntawm cov yas feem ntau yog ua los ntawm kub melting, extrusion, txhaj tshuaj molding thiab lwm yam txheej txheem los tsim cov khoom sib txawv thiab ntau thiab tsawg.Kev npaj ntawm silica gel yog tsuas yog ua los ntawm gel cov tshuaj tiv thaiv ntawm hydrated colloid, uas yuav tsum tau tswj cov tshuaj tiv thaiv kab mob, piv thiab pH tus nqi thiab lwm yam tsis, thiab ces los ntawm qhuav thiab calcination thiab lwm yam kauj ruam, thiaj li hais tias nws tsim ib silico- oxygen bond network, thiab thaum kawg tau npaj rau hauv cov khoom siv silicone.
Tsis tas li ntawd, muaj qee qhov sib txawv ntawm silicone thiab yas hauv xwm thiab siv.Cov yam ntxwv zoo ntawm cov yas yog cov rwb thaiv tsev zoo, cov khoom siv dag zog thiab tshuaj lom neeg ruaj khov, thiab lwm yam, uas tau siv dav hauv lub neej txhua hnub, kev tsim khoom thiab kev lag luam hluav taws xob.Silica gel muaj thermal stability, hnav tsis kam thiab tshuaj inertness thiab yog dav siv nyob rau hauv cov khoom noj, kev kho mob, electronics thiab aviation thiab lwm yam teb.Kev siv ntau ntawm cov khoom siv silicone muaj xws li silicone lub qhov ncauj, silicone bracelets thiab silicone seals.
Hauv cov ntsiab lus, txawm hais tias silica gel zoo ib yam li cov yas hauv qee cov khoom, muaj qhov sib txawv ntawm cov silica gel thiab yas hais txog cov qauv tshuaj, txheej txheem kev npaj thiab daim ntawv thov.Silica gel yog cov khoom siv tshwj xeeb colloidal nrog nws cov khoom tshwj xeeb thiab daim ntawv thov tus nqi.Yog li ntawd, silicone tsis yog rau cov khoom yas.
