Txuag lub sijhawm thiab khaws cov nqi pov tseg qis thaum ua qhov kev soj ntsuam kom muaj nuj nqis lossis khaws cov ntaub ntawv.Peb silane iav qauv fwj tau kho los ntawm vapor deposition silane txoj kev.Surface passivation kev kho mob xws li silanization thiab silicification yog qhov tseem ceeb los tswj kev ncaj ncees ntawm qee cov ntaub ntawv lossis cov khoom khaws cia hauv lub khob ntim.Kev hloov kho deg tuaj yeem txo qhov chaw nquag ntawm borosilicate iav nto.
Cov txheej txheem ntawm kev kho deg ntawm cov khoom siv hlau lossis cov khoom tsis yog xim hlau nrog aqueous organosilane ua cov khoom tseem ceeb.Silanization muaj qhov zoo hauv qab no tshaj li cov pa phosphating: tsis muaj teeb meem hnyav hlau ions, tsis muaj phosphorus, thiab tsis xav tau cua sov.Cov txheej txheem kho silane tsis tsim cov sediment, lub sijhawm kho yog luv, thiab kev tswj tau yooj yim.Cov kauj ruam ua haujlwm tsawg dua, cov txheej txheem kho lub rooj tuaj yeem raug tshem tawm, thiab cov kua tank tuaj yeem rov qab siv dua.Ua tau zoo txhim kho qhov adhesion ntawm cov xim rau lub substrate.Collinear ua cov ntawv hlau, galvanized ntawv, aluminium ntawv thiab lwm yam substrates.
(1) Kev kho Silane tsis muaj cov hlau hnyav xws li zinc thiab npib tsib xee thiab lwm yam khoom tsis zoo.Nickel tau raug pov thawj tias muaj kev phom sij rau tib neeg lub cev.Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb (WHO) tau teev tseg tias nickel yuav tsum raug tso tawm mus rau xoom tom qab xyoo 2016, xav kom nickel yuav tsum tsis txhob muaj phosphating dej khib nyiab, phosphating vapor thiab phosphating sib tsoo hmoov av.
(2) Silane kev kho mob tsuas yog ua rau me me ntawm silane slag, thiab cov nqi kho slag tsawg heev.
Phosphating slag yog ib qho tseem ceeb ntawm cov tshuaj tiv thaiv phosphating.Piv txwv li, ib lub tsheb ntau lawm kab uas siv txias dov daim hlau yuav tsim txog 600g ntawm phosphating slag nrog 50% noo noo cov ntsiab lus ntawm ib tug ua 1 lub tsheb (tseem 100m2), thiab ib tug ntau lawm kab ntawm 100,000 lub tsheb yuav tsim 60t ntawm phosphating slag ib xyoos twg.
(3) Tsis xav tau nitrite txhawb nqa, yog li zam kev puas tsuaj ntawm nitrite thiab nws cov khoom decomposition rau tib neeg lub cev.
(4) Cov khoom noj tsawg tsawg, tsuas yog 5% ~ 10% ntawm phosphating.
(5) Tsis muaj txheej txheem xws li kev hloov kho lub rooj thiab passivation hauv kev kho silane.Tsawg dua cov kauj ruam ntau lawm thiab lub sijhawm ua haujlwm luv luv yog pab txhawm rau txhim kho lub peev xwm ntawm lub Hoobkas, txo cov kab ntau lawm, thiab txuag cov cuab yeej siv peev thiab hauv pem teb.
(6) Chav tsev kub yog ua tau, txuag lub zog.Silane tank tov tsis tas yuav tsum tau rhuab, thiab tsoos phosphating feem ntau yuav tsum tau 35 ~ 55 ℃.
(7) Tsis muaj teeb meem nrog cov txheej txheem khoom siv uas twb muaj lawm, thiab tsis muaj cov cuab yeej hloov pauv tuaj yeem hloov ncaj qha los ntawm phosphating;Nws yog sib xws nrog cov txheej txheem txheej txheem qub thiab tuaj yeem sib xyaw nrog txhua hom xim thiab hmoov txheej siv.
Borosilicate iav yog cov khoom siv nrov rau HPLC vials vim nws muaj cov tshuaj zoo heev thiab cov khoom siv thermal.Hom iav no zoo haum rau HPLC daim ntaub ntawv vim tias nws tuaj yeem tiv taus qhov kub thiab txias thiab muaj zog hnyav uas feem ntau siv hauv HPLC.
Thaum xaiv HPLC vials, nws yog ib qho tseem ceeb uas yuav tau txiav txim siab txog hom qauv uas tau soj ntsuam thiab cov xwm txheej raws li qhov kev tshuaj xyuas yuav raug ua.Amber borosilicate iav HPLC vials nrog 9 hli qhib yog qhov kev xaiv nrov rau ntau daim ntawv thov kev sim vim lawv cov yam ntxwv ua tau zoo thiab sib haum nrog ntau yam qauv thiab cov xwm txheej.
Ntxiv rau lub vial nws tus kheej, septa kuj tseem xav tau rau HPLC tsom xam.Lub septa yog ib qho me me, ncig ntawm cov khoom uas haum rau hauv lub vial thiab ua raws li lub foob.Nws tso cai rau kev taw qhia cov qauv mus rau hauv lub vial thiab tseem muab kev tiv thaiv ntawm tus qauv thiab HPLC syringe, tiv thaiv kev sib kis.Thaum xaiv septa rau HPLC vials, nws yog ib qho tseem ceeb uas yuav tau txiav txim siab txog hom qauv uas tau soj ntsuam thiab cov xwm txheej raws li qhov kev tshuaj xyuas yuav raug ua.
