Tus neeg muab khoom siv ntawm cov neeg sawv cev ntub dej txhim khu kev qha
Cov Khoom Siv Lub Cev Thiab Tshuaj
Cov neeg sawv cev ntub dej, ib hom polyorganosiloxane nrog cov qauv saw hlau ntawm ntau qib polymerization, ua haujlwm ua tus neeg sawv cev ntub dej zoo kawg nkaus. Nws yog tsim los ntawm hydrolysis ntawm dimethyldichlorosilane thiab dej kom tau txais lub nplhaib condensation thawj zaug. Lub nplhaib ces tawg, kho kom raug los tsim lub nplhaib Chemicalbook qis, thiab ua ke nrog tus neeg sawv cev taub hau thiab tus catalyst rau polymerization. Cov txheej txheem no ua rau muaj ntau yam sib xyaw ntawm cov neeg sawv cev ntub dej nrog ntau qib ntawm polymerization. Cov khoom sib xyaw qis qis raug tshem tawm los ntawm kev distillation nqus tsev kom tau txais cov neeg sawv cev ntub dej kawg.
Sib nrug los ntawm kev ua tus neeg sawv cev ntub dej, roj silicone muaj ntau yam ntxwv thiab kev siv. Nws feem ntau siv ua tus neeg ua npuas dej hauv kev lag luam xws li kev ua zaub mov, kev tsim khoom siv pleev ib ce, thiab kev ua ntawv. Los ntawm kev txo cov npuas dej ua kom zoo, roj silicone txhim kho tag nrho cov txheej txheem tsim khoom. Tsis tas li ntawd, nws siv ua cov khoom xyaw tseem ceeb hauv kev tsim cov silicone resin thiab silicone roj hmab. Cov ntaub ntawv no pom ntau daim ntawv thov raws li cov nplaum, cov khoom siv yas tiv thaiv hluav taws, cov khoom siv rwb thaiv tsev, thiab ntau ntxiv.
Qhov ua tau ntau yam ntawm cov roj silicone kuj qhia tau ntxiv los ntawm nws txoj haujlwm ua tus neeg sawv cev tiav hauv kev lag luam tawv. Nws pab txhim kho qhov zoo nkauj, kev ntxhib los mos, thiab kev ruaj khov ntawm cov khoom tawv. Ntxiv mus, hauv ntau lwm yam kev lag luam, xws li kev tsim cov tshuaj ntxuav zoo, nws tsis yog tsuas yog ua tus neeg sawv cev ntub dej xwb tab sis kuj ua haujlwm ua cov khoom xyaw tseem ceeb rau kev tsim cov qauv thiab kev ruaj khov.
Qhov zoo
(1) Qhov kev ua tau zoo ntawm viscosity yog qhov zoo tshaj plaws hauv cov roj nplua nyeem kua, thiab qhov kev hloov pauv viscosity hauv qhov kub dav yog me me. Nws cov ntsiab lus condensate feem ntau tsawg dua -50 ° C, thiab qee qhov yog txog li -70 ° C. Nws khaws cia rau lub sijhawm ntev ntawm qhov kub qis. Cov tsos thiab viscosity ntawm nws cov khoom roj tsis tau hloov pauv. Nws yog cov roj yooj yim uas coj mus rau hauv tus account qhov kub siab, kub qis, thiab ntau yam kub.
(2) Kev ruaj khov zoo heev ntawm kev ua kom sov thermal oxidation, xws li qhov kub thiab txias ntawm kev rhuav tshem thermal> 300 ° C, qhov poob me me ntawm kev ua kom qhuav (150 ° C, 30 hnub, qhov poob ntawm kev ua kom qhuav tsuas yog 2%), kev sim oxidation (200 ° C, 72H), kev hloov pauv ntawm viscosity thiab acid me me.
(3) Kev rwb thaiv hluav taws xob zoo heev, tiv taus ntim, thiab lwm yam. Hauv qhov kub ib txwm ～ 130 ℃, nws tsis hloov pauv (tab sis cov roj tsis tuaj yeem yog dej).
(4) Nws yog cov roj tsis muaj tshuaj lom thiab ua npuas dej tsawg thiab muaj zog tiv thaiv npuas, uas siv tau ua lub muffler.
(5) Kev ruaj khov zoo heev, uas tuaj yeem nqus tau kev co thiab tiv thaiv kev sib kis ntawm kev co.
