Silane ruaj khov npaum li cas?

Silanemuaj kev ruaj khov tsis zoo thiab muaj cov yam ntxwv hauv qab no.

1. Rhiab rau huab cua

Yooj yim rau nws tus kheej hlawv:SilaneNws tuaj yeem ua rau nws tus kheej kub hnyiab thaum sib cuag nrog huab cua. Ntawm qee qhov kev sib xyaw, nws yuav ua rau muaj kev kub ntxhov nrog cov pa oxygen thiab tawg txawm tias qhov kub qis dua (xws li -180 ℃). Lub nplaim taws yog xim daj tsaus thaum nws hlawv. Piv txwv li, thaum lub sijhawm tsim khoom, khaws cia thiab thauj mus los, yog tias silane xau thiab sib cuag nrog huab cua, nws yuav ua rau muaj kev sib xyaw ua ke lossis txawm tias muaj kev sib tsoo tawg.

Yooj yim kom oxidized: Cov khoom siv tshuaj lom neeg ntawmsilanemuaj zog ntau dua li alkanes thiab yooj yim oxidized. Cov tshuaj tiv thaiv oxidation yuav ua rau muaj kev hloov pauv hauv cov qauv tshuaj ntawm silane, yog li cuam tshuam rau nws cov kev ua tau zoo thiab kev siv.

2. Rhiab rau dej

Silanenws yooj yim hydrolysis thaum kov dej. Qhov hydrolysis reaction yuav tsim hydrogen thiab cov silanols sib xws thiab lwm yam tshuaj, yog li hloov cov tshuaj lom neeg thiab lub cev ntawm silane. Piv txwv li, nyob rau hauv ib puag ncig noo noo, qhov ruaj khov ntawm silane yuav raug cuam tshuam loj heev.

3. Kev ruaj khov raug cuam tshuam los ntawm qhov kub thiab txias

Kev hloov pauv ntawm qhov kub thiab txias tuaj yeem muaj kev cuam tshuam loj heev rausilanekev ruaj khov. Nyob rau hauv qhov kub thiab txias siab, silane yog qhov yooj yim rau kev lwj, polymerization thiab lwm yam kev cuam tshuam; nyob rau hauv qhov kub thiab txias qis, qhov kev ua haujlwm ntawm silane yuav raug txo qis, tab sis tseem yuav muaj kev tsis ruaj khov.
