YSilicon vs Silicone
Txawm hais tias silicon thiab silicone zoo li yog tib lo lus ntawm ib nrais muag, lawv raug xa mus rau txhua yam sib txawv.
Silicon
Silicon yog lub caij nrog atomic tooj 14, thiab nws kuj yog nyob rau hauv pawg 14 ntawm lub sij hawm hauv qab cov pa roj carbon. Nws yog qhia los ntawm lub cim Si. Nws txoj kev teeb tsa hluav taws xob yog 1s2 2s2 2p6 3s23p2 Silicon tuaj yeem tshem plaub lub tshuab hluav taws xob thiab tsim ib qho +4 them cation, lossis nws tuaj yeem faib cov electrons los ua plaub daim ntawv cog lus. Silicon yog tus yam ntxwv raws li metalloid vim nws muaj ob qho tib si hlau thiab nonmetal zog. Silicon yog ib qho nyuaj thiab inert metalloid khoom. Melting point ntawm silicon yog 1414 o C, thiab qhov kub kub yog 3265 o C. Crystal zoo li silicon yog nkig heev. Nws tshwm sim tsis tshua muaj raws li ntshiab silicon nyob rau hauv qhov xwm txheej. Feem ntau, nws tshwm sim raws li oxide los yog silicate. Txij li thaum silicon tiv thaiv nrog txheej txheej oxide, nws tsis tshua muaj kev cuam tshuam rau cov tshuaj lom neeg. Kub kub yog xav tau rau nws kom oxidize. Piv txwv li, silicon reacts nrog fluorine nyob rau hauv chav tsev kub. Silicon tsis hnov mob nrog acids tab sis reacts nrog concentrated alkalis.
Muaj ntau ntau kev lag luam siv ntawm silicon. Silicon yog ib tug semiconductor, yog li ntawd, siv nyob rau hauv computers thiab electronics. Silicon tebchaw zoo li silica los yog silicates yog dav siv nyob rau hauv ceramic, iav thiab cement industries.
YSilicon
Silicone yog polymer. Nws muaj cov khoom silicon tov nrog lwm cov ntsiab lus xws li carbon, hydrogen, oxygen, thiab lwm yam. Nws muaj cov qauv molecular ntawm [R 2 SiO nNtawm no, pawg R tuaj yeem yog methyl, ethyl lossis phenyl. Cov pab pawg no txuas nrog silicon atom, uas yog nyob rau hauv lub xeev +4 oxidation thiab, los ntawm ob sab oxygen atoms txuas rau silicon ua ib tug Si-O-Si qaum. Yog li silicone tuaj yeem hu ua polymerized siloxanes lossis polysiloxanes. Nyob ntawm seb muaj pes tsawg leeg thiab cov khoom, silicone tuaj yeem muaj qhov sib txawv morphologies. Lawv tuaj yeem ua kua, gel, roj hmab lossis yas tawv. Muaj cov roj silicone, silicone roj hmab, silicone resin thiab silicone roj. Silicone yog tsim los ntawm silica, uas yog nyob rau hauv cov xuab zeb. Silicone muaj cov khoom siv tau zoo heev xws li cov thermal conductivity tsawg, tsis tshua muaj tshuaj reactivity, tsis tshua muaj toxicity, resistant rau microbiological kev loj hlob, thermal stability, muaj peev xwm los tiv thaiv dej, thiab lwm yam. Thiab tseem vim nws lub peev xwm tiv thaiv dej nws yog siv los ua cov pob qij txha los tiv thaiv cov dej ntws. Txij li thaum nws tuaj yeem tiv taus cua sov, nws yog siv los ua cov roj nplua nyeem hauv tsheb. Nws yog siv ntxiv los ua cov kuab tshuaj qhuav qhuav, ua cov txheej txheem cookware, hauv cov khoom siv hluav taws xob, cov nplaim hluav taws, thiab lwm yam. Ntxiv mus, nws yog siv nyob rau hauv kom hniav zoo nkauj phais. Txij li silicone tsis muaj tshuaj lom, nws yog siv los tsim cov khoom siv dag zog hauv lub cev xws li tawg los cog rau hauv. Feem ntau cov silicone gels yog siv rau lub hom phiaj no. Feem ntau cov khoom siv tshuaj pleev ib ce yog tsim nrog silicone hnub no. Cov tshuaj zawv plaub hau, tshuaj zawv plaub hau, tshuaj pleev plaub hau, roj plaub hau, thiab cov gels yog qee yam ntawm cov khoom siv silicone.
Qhov txawv ntawm Silicon thiab Silicone yog dab tsi?
• Silicon yog ib yam khoom thiab silicone yog polymer.
• Silicon yog ib txwm pom nyob rau hauv ib puag ncig, whereas silicone yog manmade.
• Silicone muaj silicon, uas txuas nrog lwm cov khoom xws li carbon, oxygen thiab hydrogen.
• Silicon is comparatively reactive dua silicone.
• Silicone tuaj yeem ua kua, gel, roj hmab lossis yas tawv thaum silicon yog ib qho khoom.
• Kev lag luam siv ntawm silicon thiab silicone txawv. Silicon feem ntau yog siv los ua ib qho semiconductor whereas silicone muaj ntau lwm yam kev siv raws li tau hais los saum toj no.
