Qhov sib txawv tseem ceeb ntawm silane thiab siloxane yog tias silane yog tshuaj lom neeg thaum siloxane yog ib pawg ua haujlwm hauv organosilicon.

Silane thiab siloxane yog cov khoom siv silicone. Ob qho khoom siv no tseem ceeb heev li sealers. Ntawm no, silane sealer nyiam nkag mus tob rau hauv qab qhov chaw tiv thaiv thaum siloxane sealer ua haujlwm rau saum npoo rau dej.

Silane yog dab tsi?

Silane yog ib qho inorganic compound uas muaj cov tshuaj formula SiH4 Nws yog ib pawg 14 hydride. Tsis tas li ntawd, cov khoom no tshwm sim raws li cov roj tsis muaj xim uas muaj ntxhiab tsw ntxhiab. Cov ntxhiab tsw zoo ib yam li cov ntxhiab ntawm acetic acid. Nws molar mass yog 32.11 g / mol. Tsis tas li, txoj kev lag luam feem ntau tshaj plaws rau kev tsim cov silane yog cov tshuaj tiv thaiv ntawm hydrogen chloride nrog magnesium silicide.

Daim duab 01: Cov qauv ntawm Silane Molecule

Cov duab ntawm silane molecule yog tetrahedral, zoo ib yam li methane molecule. Vim tias qhov sib txawv loj ntawm cov txiaj ntsig electronegativity ntawm silicone thiab hydrogen, nws muaj qhov sib txawv polarity rau cov methane. Vim qhov no rov qab polarity, silane tuaj yeem tsim cov complexes nrog cov hlau hloov pauv. Tsis tas li ntawd, silane tuaj yeem cuam tshuam qhov tshwm sim ntawm huab cua. Qhov ntawd txhais tau tias; nws tsis tas yuav muaj qhov hluav taws kub sab nraud. Tsis tas li ntawd, qhov tseem ceeb ntawm daim ntawv thov ntawm silane yog qhov ua ntej rau kev tsim cov khoom siv silicon. Qhov no yog qhov tseem ceeb hauv kev tsim khoom semiconductor. Nws kuj tseem siv tau los ua lub sealer.

YSiloxane yog dab tsi?

Siloxane yog pab pawg ua haujlwm muaj Si-O-Si txuas. Cov pab pawg ua haujlwm muaj nyob hauv organosilicon tebchaw. Cov tshuaj siloxane tuaj yeem yog cov sib txuas ncaj nraim lossis cov kab sib txuas. Cov kev sib txuas no tsim cov caj qaum ntawm silicone polymer, i.e. polydimethylsiloxane.

Daim duab 02: Siloxane Linkage

Tsis tas li ntawd, txoj hauv kev tseem ceeb ntawm kev sib txuas ntawm siloxane yog los ntawm condensation ntawm ob silanols. Peb tuaj yeem tsim silanol los ntawm hydrolysis ntawm silyl chloride. Qhov sib xyaw no kuj tseem ceeb hauv kev ua silicon carbide thaum ignition nyob rau hauv ib qho chaw inert. Ntxiv mus, siloxane polymers muaj txiaj ntsig zoo li sealers rau cov dej tsis zoo.

Qhov txawv ntawm Silane thiab Siloxane yog dab tsi?

Silane yog ib qho inorganic compound uas muaj cov tshuaj formula SiH4 thaum Siloxane yog ib pab pawg ua haujlwm muaj Si-O-Si txuas. Qhov sib txawv tseem ceeb ntawm silane thiab siloxane yog tias silane yog cov tshuaj lom neeg thaum siloxane yog ib pawg ua haujlwm hauv organosilicon. Tsis tas li ntawd, daim ntawv thov tseem ceeb ntawm Silane yog siv nws ua tus thawj coj rau kev tsim cov khoom siv silicon, thaum siloxane tseem ceeb hauv kev ua silicon carbide.

Hauv qab infographic qhia ntau qhov kev sib piv ntsig txog qhov sib txawv ntawm silane thiab siloxane.
