Qhov sib txawv tseem ceeb ntawm silicone thiab siloxane yog silicone yog cov khoom siv polymer thaum siloxane yog ib pab pawg ua haujlwm.
Txawm tias peb siv cov ntsiab lus silicone thiab siloxane sib hloov, lawv sib txawv heev; siloxane yog ib pab pawg ua haujlwm thaum silicone yog cov khoom muaj cov pab pawg ua haujlwm no.
Y Silicone yog dab tsi?
Silicone yog cov khoom siv polymer uas muaj ntau pawg siloxane ua haujlwm thoob plaws hauv nws cov qauv. Yog li ntawd, peb tuaj yeem hu cov khoom no polysiloxane. Nws yog ib qho hluavtaws polymer uas tsis tshwm sim hauv qhov xwm txheej. Cov khoom no muaj cov pob txha, uas muaj Si-O bonds. Tsis tas li ntawd, muaj cov hlua txuas txuas rau lub caj qaum no. Peb feem ntau xav txog qhov no yog ib qho inorganic polymer vim tias nws tsis muaj cov pa roj carbon monoxide hauv nws cov caj qaum.
Daim duab 01: Rov Ua Haujlwm ntawm Polysiloxane
Vim tias kev sib cog lus ntawm Si-O muaj zog dua, cov pob txha caj qaum muaj zog dua li cov pob txha muaj carbon. Vim tib qho laj thawj, cov khoom siv no tiv taus kub heev.
YSiloxane yog dab tsi?
Siloxane yog pab pawg ua haujlwm muaj Si-O-Si txuas. Cov pab pawg ua haujlwm no 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. polymethylsiloxane.
Daim duab 02: Siloxane Functional Group
Txoj hauv kev tseem ceeb ntawm kev sib txuas ntawm siloxane yog los ntawm kev sib xyaw ntawm ob silanols. Peb tuaj yeem tsim silanol los ntawm hydrolysis ntawm silyl chloride. Qhov sib xyaw no 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 Silicone thiab Siloxane yog dab tsi?
Silicon thiab siloxane tsis zoo ib yam. Qhov sib txawv tseem ceeb ntawm silicone thiab siloxane yog silicone yog cov khoom siv polymer thaum siloxane yog ib pab pawg ua haujlwm. Tsis tas li ntawd, silicone muaj ntau pawg siloxane rov ua dua thoob plaws hauv cov qauv thaum cov qauv ntawm siloxane yog Si-O-Si daim ntawv cog lus. Thaum xav txog kev ruaj ntseg, silicone yog qhov ruaj khov heev vim yog Si-O-Si qaum qaum uas tsis muaj cov pa roj carbon-carbon bonds thiab Siloxane tsis ruaj khov vim tias nws yog ib pab pawg ua haujlwm thiab nyiam ua rau cov molecule lossis polymer.
Summary – Silicone vs Siloxane
Nws muaj qhov sib txawv ntawm silicone thiab siloxane txawm hais tias peb siv cov ntsiab lus silicone thiab siloxane sib hloov. Silicone yog cov khoom siv polymer thaum siloxane yog pawg ua haujlwm.
