Qhov kev daws teeb meem tiag tiag nyob rau hauv kev hloov kho qhov chaw - Tsis yog nyob rau hauv cov xim nws tus kheej
Nyob rau hauv ob lub zog ntawm cov hom phiaj tsis muaj pa roj carbon thiab cov kev cai ib puag ncig nruj, cov lag luam xws li cov khoom siv sab hauv tsheb, cov khoom siv hauv tsev, thiab cov khoom siv 3C tab tom hloov pauv sai sai ntawm cov txheej txheem ua los ntawm cov kuab tshuaj. Kev hloov mus rau cov txheej txheem txheej txheem dej tau hloov pauv los ntawm kev xaiv mus rau qhov tseem ceeb.
Txawm li cas los xij, kev hloov pauv no tsis yog yam tsis muaj teeb meem. Ntau lub tuam txhab tsim khoom tau ntsib teeb meem xws li xim pleev xim tawg, khawb, thiab cov txiaj ntsig tsis zoo ntawm kev sib txuas tom qab hloov mus rau cov txheej txheem dej. Cov txiaj ntsig tsis sib xws thaum lub sijhawm tsim khoom loj tau ua rau muaj kev tsis ruaj khov ntawm kev tsim khoom ntxiv.
Rau feem ntau cov chaw tsim khoom, qhov kev teb tsis zoo yog "siv cov xim zoo dua." Txawm li cas los xij, txawm tias tom qab ntau qhov kev hloov kho rau cov qauv txheej, qhov teeb meem lo rau tseem muaj. Qhov teeb meem tiag tiag tsis yog nyob rau hauv cov txheej txheej dej nws tus kheej tab sis nyob rau hauv qhov tsis txaus ntawm qhov chaw ntawm cov yas substrate - thaum lub substrate tsis ua raws li qhov yuav tsum tau lo rau, txawm tias cov xim zoo tshaj plaws tsis tuaj yeem ua tiav kev sib txuas ruaj khov.
I. Qhov Ua Rau: Cov Yas thiab Cov Txheej Txheem Dej Tsis Sib Xws Li Ntuj Tsim
Qhov teeb meem ntawm kev sib txuas ntawm cov yas thiab cov xim pleev dej yog los ntawm qhov tsis sib xws ntawm cov khoom siv, feem ntau yog vim peb yam tseem ceeb:
1. Lub zog qis ntawm qhov chaw - Kev txheej tsis ua rau cov khoom ntub
Cov yas xws li ABS, PP, thiab PC, uas siv dav hauv cov khoom siv sab hauv tsheb, feem ntau muaj lub zog ntawm qhov chaw ntawm 20–40 mN/m2. Qhov sib txawv, cov txheej txheem dej yuav tsum muaj lub zog ntawm qhov chaw ntawm tsawg kawg 50 mN/m2 rau kev ntub thiab kis tau zoo.
Qhov xwm txheej no zoo ib yam li cov dej ntws tawm ntawm nplooj paj - lub zog qis ntawm qhov chaw tiv thaiv kev sib cuag nruj, ua rau muaj "txheej ntab" uas tsis muaj zog uas tev tawm yooj yim thaum muaj kev ntxhov siab.
2. Polarity Mismatch — Kev Sib Txuas Lus Tsis Zoo
Cov txheej txheem dej, yog cov txheej txheem polar nrog dej ua tus nqa khoom, vam khom electrostatic thiab hydrogen bonding interactions. Feem ntau cov yas xws li PP thiab PE yog cov khoom siv tsis-polar nrog cov qauv molecular ruaj khov thiab tsis muaj qhov chaw sib txuas nquag. Qhov tsis muaj kev sib raug zoo ntawm cov tshuaj lom neeg ntawm ob cov ntaub ntawv ua rau muaj kev sib txuas tsis muaj zog - zoo li qhov tsis sib xyaw ntawm roj thiab dej.
3. Kev Ua Phem Rau Qhov Chaw Thiab Cov Khoom Pwm Uas Tso Tawm
Thaum lub sijhawm ua yas, cov tshuaj tua pwm thiab lwm yam khoom ntxiv yuav ya mus rau saum npoo. Txawm tias qhov khoom ntawd zoo li huv si rau qhov muag liab qab, cov khoom seem me me ntawm silicone lossis cov roj seem tsim ib qho thaiv uas tsis pom uas tiv thaiv kev sib cuag ncaj qha ntawm cov txheej thiab cov khoom siv, ua rau thaiv kev lo.
Qhov tseem ceeb, cov xim pleev xim hauv cov txheej txheem dej tsis yog qhov tsis zoo ntawm cov txheej, tab sis yog qhov tshwm sim ntawm cov yas uas tsis tau kho lossis tsis ua haujlwm txaus uas tsis muaj kev sib raug zoo ntawm cov molecular uas xav tau rau kev sib txuas ruaj khov.
II. Cov Kev Txwv ntawm Cov Txheej Txheem Kho Nto Ib Txwm Muaj
Yuav kom txhim kho kev nplaum, ntau txoj kev kho ua ntej tau siv - tab sis feem ntau tsuas yog muab kev txhim kho ib ntus lossis theem saum npoo xwb.
Kev Kho Mob Hluav Taws Xob lossis Corona: Cov txheej txheem no ua rau lub zog ntawm qhov chaw nce ntxiv ib ntus tab sis lwj sai sai hauv ob peb teev lossis ob peb hnub vim muaj kev laus. Lawv cov txiaj ntsig ntawm cov qauv nyuaj xws li cov qhov tob lossis cov ces kaum ntse ntse raug txwv los ntawm kev tsis sib xws.
Kev Kho Mob Plasma Hauv Huab Cua: Txawm hais tias muaj peev xwm qhia txog cov pab pawg polar, cov tshuab plasma muab cov zog tsawg thiab kev npog tsis zoo ntawm cov chaw 3D. Cov khoom siv siab thiab cov nqi ua haujlwm ntxiv txwv tsis pub scalability.
Kev Siv Tshuaj Tua Hluav Taws Xob Los Yog Kev Pleev Xim Rau Sab Nraud: Kev siv tshuaj tua hluav taws xob muaj cov kua qaub los yog alkalis muaj zog, ua rau muaj teeb meem rau ib puag ncig thiab kev pov tseg dej khib nyiab. Kev pleev xim rau sab nraud ua rau muaj kev tso pa tawm VOC ntxiv thiab ua rau cov nqi khoom siv thiab cov nqi zog ua haujlwm nce ntxiv, uas tsis sib haum nrog lub hom phiaj ntawm kev tsim khoom ruaj khov.
Tag nrho cov txheej txheem ib txwm muaj no tseem yog "kev kho mob sab nraud" - lawv hloov kho qhov chaw sab nraud tsuas yog superficially yam tsis tau ua tiav kev ua haujlwm mus tas li hauv cov qauv polymer.
III. Kev Tshawb Fawb Txog Kev Siv Tshuab: Kev Siv Fluorination Hauv Tshuab Nqus Tsev - Kev daws teeb meem ob qho rau kev nplaum thiab kev ruaj khov
Tsis zoo li kev kho qhov chaw sab nraud, kev siv lub tshuab nqus tsev fluorination ua tiav kev hloov kho ntawm cov qauv ntawm cov polymer interface.
Cov txheej txheem no ua rau cov pa roj fluorine uas muaj cov tshuaj tiv thaiv mus rau hauv lub tshuab nqus tsev uas tswj tau, qhov chaw uas lawv ua cov tshuaj tiv thaiv uas raug, tswj tau nrog cov polymer cov molecules saum npoo av. Qhov tshwm sim yog ib txheej polar interface ruaj khov nrog lub zog thiab polarity ntawm saum npoo av uas txhim kho zoo heev.
Qhov kev hloov kho no ua rau lub substrate ntub dej thiab sib haum xeeb nrog cov txheej txheem dej, ua rau muaj kev ua tau zoo hauv kev lag luam.
Qhov tseem ceeb ib yam li ntawd, kev siv lub tshuab nqus tsev los ua kom muaj fluorination hauv qhov chaw kaw, tsis muaj pa phem, thiab tsis muaj cov khib nyiab tawm. Yog li ntawd, nws yog ib qho thev naus laus zis ntsuab thiab ua tau zoo uas ua rau kev txhim kho kev nplaum zoo nrog cov ntsiab cai tsim khoom ruaj khov.
IV. Los ntawm Kev Siv Tshuab Mus Rau Kev Lag Luam: ZhenHua Vacuum's Plastic Surface Fluorination Solution
Siv ntau xyoo ntawm kev txawj ntse hauv kev kho qhov chaw nqus tsev thiab thev naus laus zis nyias-zaj duab xis, ZhenHua Vacuum tau ua kom cov txheej txheem nqus tsev fluorination ua lag luam mus rau hauv lub platform khoom siv uas laus lawm, npaj txhij rau kev tsim khoom, pab cov chaw tsim khoom daws cov teeb meem kev nplaum ntawm cov txheej txheem dej thaum tswj hwm kev ua raws li ib puag ncig tag nrho.
Cov kev daws teeb meem no tau ua tiav los ntawm ntau tus thawj coj hauv kev lag luam hauv kev tsim kho sab hauv tsheb, cov khoom siv tshuaj lom neeg, thiab cov khoom siv hluav taws xob, uas qhia tau tias muaj kev ntseeg siab thiab kev nthuav dav.
Cov txiaj ntsig tseem ceeb ntawm ZhenHua Vacuum cov khoom siv kho qhov chaw yas
Kev nplaum zoo dua rau cov txheej txheem dej
Cov thev naus laus zis hloov kho qhov chaw raws li fluorine ua rau muaj qhov polarity thiab hydrophilicity ntawm qhov chaw ntau ntxiv, daws tau qhov teeb meem ntawm kev nplaum hauv cov kab ke dej.
Kev Txhim Kho Kev Ua Haujlwm Zoo
Qhov chaw kho mob muaj cov yam ntxwv zoo tshaj plaws thiab ua tau ntev, ua rau kev ruaj khov thiab lub neej ntawm cov khoom sab hauv tsheb zoo dua.
Haum rau Cov Qauv Geometries Nyuaj
Cov txheej txheem txheej txheem tuaj yeem hloov kho tau yooj yim kom haum rau cov khoom 3D thiab cov khoom sib txawv, kom ntseeg tau tias muaj kev hloov pauv zoo ib yam thiab kev ua haujlwm ntawm cov txheej txheem sib xws.
Cov Ntawv Thov
Siv tau rau kev lag luam tsheb, tshuaj lom neeg, khoom siv hluav taws xob, ntim khoom, thiab cov yeeb yaj kiab polymer.
Xaus lus
Thaum "txheej ntsuab" dhau los ua ib qho kev taw qhia tseem ceeb hauv kev hloov pauv kev tsim khoom, kev txheej dej ntawm cov yas tsis yog qhov xaiv tau lawm - nws yog qhov tseem ceeb.
Kev siv cov tshuaj fluorination hauv lub tshuab nqus tsev ua rau muaj kev hloov pauv hauv kev tsim kho qhov chaw, muab kev daws teeb meem molecular los txuas qhov tsis sib xws ntawm cov yas thiab cov txheej txheem dej.
Txij li kev tsim kho tshiab txog kev siv tshuab mus rau kev siv hauv kev lag luam, ZhenHua Vacuum tau ua pov thawj tias tsuas yog los ntawm kev daws qhov teeb meem ntawm qhov sib txuas ntawm cov khoom siv tuaj yeem ua rau cov tuam txhab tsim khoom ua tiav kev ua haujlwm ruaj khov, ua haujlwm tau zoo, thiab ruaj khov ntawm cov dej txheej ntawm cov yas.
