Ib tug. Luv -} lub sij hawm kub txog kev
Kev ua qhov kub thiab txias (tsawg dua los yog sib luag rau 80 degree): 204 Silicone Roj tuaj yeem tiv thaiv kev tiv thaiv nyob rau hauv kev lag luam xws li tshuaj pleev ib ce, pleev xim, thiab textiles. Piv txwv li:
Ntxiv rau tshuaj pleev ib ce tom qab emulsification thiab txias rau 40-50 degree.
Muaj kev kub ntxhov ntau hauv cov tshuaj lom fiber tag dhau los ua tiav.
Nws sib xyaw nrog cov resins nyob rau hauv dej - Raws cov txheej ntau lawm.
Nyob rau hauv qhov ntsuas kub no, nws cov qauv molecular tseem ruaj khov, thiab nws cov khoom tsis hloov pauv.
Luv - Term Peak 17}}}}} Cov tswv yim tshwj xeeb yuav muaj ncua tshwj xeeb): {} {{100 kub dirring). Thaum 204 cov roj silicone feem ntau tuaj yeem tiv thaiv cov ntsuas kub, lub sijhawm ntev yog tsis pom zoo.
Ob. Cov pheej hmoo tseem ceeb thiab kev ua haujlwm ntawm cov tshuab kub ntawm cov kub
Thaum kub tshaj qhov lawv ua siab ntev los yog siv rau ncua sijhawm, ob qho kev pauv hloov ua ntej
Oxidative decomposition (tseem pheej hmoo)
Silicone ROJ BACKUMS (SI {{}}}} {1} {1} {1} Si) Qhov no txo cov roj silicone lub viscosity thiab txoj kev pom zoo nws lubricity thiab zaj duab xis - ua cov khoom.
Polyether Chain Scrappy thiab Kev Txwv
Qhov no yog qhov sib xyaw uas tsis yooj yim tshaj plaws ntawm 204 roj silicone. Nws cov dej solubility thiab sib xyaw tau nyob ntawm polyether (EO / PO) pawg nyob hauv nws sab saw.
Kev kub siab txhawb oxidation, hydrolysis, thiab saw saw ntawm ntu ntu. Thaum cov ntaub pua tes polyeth, 204 roj silicone los ua rau cov roj av lossis dej ntws tawm, ua kom tiav nws txoj haujlwm li dej- solicle silicone roj.
Peb. Cov Ntsiab Lus Tseem Ceeb cuam tshuam rau qhov kub tsis kam
Muaj cov pa tawm (O₂): qhov kub tsis kam yog hloov kho hauv cov pa - ib puag ncig. Lub xub ntiag ntawm kev oxygen tau sai sai nrawm nrawm oxidative kev deb ntawm qhov kub.
System PH: hauv qab cov muaj zog acidic lossis alkaline tej yam kev mob (mob heev pH), kub siab dua nrawm nrawm nrawm nrawm.
Muaj cov catalysts: qee cov hlau ions (tshwj xeeb yog cov calcium, magnesium, thiab cov tshuaj sib xyaw tuaj yeem ua kom mob oxidation thiab hydrolysis kev tawm tsam, txo thermal stability. Qhov no yog vim li cas dilution nrog dej deionized yog qhov tseem ceeb heev.
Plaub. Cov tswv yim cov lus pom zoo
Thaum lub sijhawm ua thiab daim ntawv thov: Khaws cov cua sov kub hauv qab 80℃thiab txo cov cua sov. Yog hais tias siab - kub kev ua yog yuav tsum tau, ua ib qho me me- nplai ntsuas kom paub tseeb ruaj khov.
Cia: Ib txwm khaws cia rau hauv qhov chaw txias, tsaus (qis dua 40 degree), deb ntawm tshav kub thiab hluav taws kub. Zam kev ntev kom sov sai sai (xws li hauv ib lub tsheb thaum lub caij ntuj sov lossis ze chav boiler).
Tsim qauv tsim:
Yog tias koj cov khoom kawg yuav xav tau ntev - Lub sijhawm ua haujlwm nyob rau hauv lub siab (xws li}}} solubble silicone kua yuav tsis yog qhov kev xaiv zoo tshaj plaws.
Txiav txim siab siv ntau dua cua sov - Resistant Silicone kua lossis cov no feem ntau tsis ywg dej silicone, tab sis cov no tsis yog dej {{3} soluble.
Kev kuaj thiab ntawv pov thawj: ua ntej loj loj {{0} teev ntau lawm, thermal kev xeem ntawv yog qhov tseem ceeb. Raug cov qauv muaj 204 kua dej silicone rau qhov kub siab xav tau rau koj cov txheej txheem rau ib lub sijhawm. Tom qab txias, saib seb tus qauv puas pom tseeb, pob tshab, thiab cov khaub ncaws hnav. Tsis tas li, sim nws cov khoom (xws li dej solubility, nto nro, thiab lubricity) saib seb puas muaj qhov tshwm sim.
204 Dej - Soluble Silicone Roj tuaj yeem ua kom tau cov txheej txheem luv, tab sis nws tsis yog tsim rau cov txheej txheem luv, tab sis nws tsis yog qhov tseeb -}}}}}}} qhov chaw dej sov. Nws cov kev txwv ruaj khov yog kwv yees li 80-120 degree. Dhau qhov kev kub siab no lossis ntev dhau los, ntu kev sib deev yuav txwv, ua rau poob dej solubility thiab kev ua tsis tiav. Ua tib zoo ntsuas koj cov ntawv thov kub thiab xyuas nws los ntawm kev sim sim yog qhov tseem ceeb los ua kom tiav daim ntawv thov kev vam meej.
