Cov txiaj ntsig ntawm cov tshuaj ntxuav plasma yog dab tsi?

Lub tshuab ntxuav plasma (plasma cleaner), tseem hu ua plasma cleaner, lossis plasma surface treatment instrument, yog ib qho thev naus laus zis tshiab, kev siv plasma los ua kom tiav cov txiaj ntsig ntawm cov txheej txheem ntxuav ib txwm tsis tuaj yeem ua tiav. Plasma yog lub xeev ntawm cov khoom, tseem hu ua lub xeev plaub ntawm cov khoom, tsis yog cov khoom siv khov-kua-roj peb lub xeev. Siv zog txaus rau cov roj kom dissociate nws mus rau hauv lub xeev plasma. Cov khoom "active" ntawm plasma suav nrog ions, electrons, atoms, active groups, excited nuclides (metastable), photons, thiab lwm yam. Lub tshuab ntxuav plasma yog siv cov khoom ntawm cov khoom no los kho qhov chaw ntawm cov qauv, yog li ua tiav lub hom phiaj ntawm kev ntxuav, txheej, thiab lwm yam.

Yog li ntawd, qhov zoo yog dab tsi? Ua ntej, cov khoom ntxuav yuav qhuav tom qab ntxuav plasma, thiab nws tuaj yeem xa mus rau cov txheej txheem tom ntej yam tsis tau ziab. Yuav txhim kho qhov ua tau zoo ntawm tag nrho cov txheej txheem; Ob, kev ntxuav plasma ua rau cov neeg siv nyob deb ntawm cov kuab tshuaj phem uas ua rau tib neeg lub cev puas tsuaj, tab sis kuj zam qhov teeb meem ntawm kev ntxuav ntub yog yooj yim ntxuav cov khoom ntxuav; Peb, zam kev siv trichloroethane thiab lwm cov kuab tshuaj phem, yog li yuav tsis muaj cov kuab tshuaj phem tom qab ntxuav, yog li txoj kev ntxuav no yog rau kev tiv thaiv ib puag ncig ntawm txoj kev ntxuav ntsuab. Qhov no ua rau muaj kev txhawj xeeb thoob ntiaj teb rau kev tiv thaiv ib puag ncig; Plaub, cov plasma tsim los ntawm qhov zaus siab ntawm cov nthwv dej xov tooj cua txawv ntawm lub teeb ncaj qha xws li laser. Plasma tsis yog qhov taw qhia heev, uas tso cai rau nws mus txog tob rau hauv cov qhov me me thiab cov qhov ntawm ib yam khoom kom ua tiav nws txoj haujlwm ntxuav yam tsis muaj kev txhawj xeeb ntau rau cov duab ntawm cov khoom raug ntxuav. Thiab cov nyhuv ntxuav ntawm cov khoom nyuaj no zoo ib yam lossis zoo dua li ntawm kev ntxuav freon; Tsib, kev siv plasma ntxuav, tuaj yeem ua rau kev ua haujlwm ntxuav tuaj yeem txhim kho zoo heev. Tag nrho cov txheej txheem ntxuav tuaj yeem ua tiav hauv ob peb feeb xwb, yog li nws muaj cov yam ntxwv ntawm cov txiaj ntsig siab; Rau, kev ntxuav plasma yuav tsum tswj qhov degree nqus tsev yog li 100Pa, qhov xwm txheej ntxuav no yooj yim ua tiav. Yog li ntawd, tus nqi khoom siv ntawm lub cuab yeej no tsis siab, thiab cov txheej txheem ntxuav tsis tas yuav siv cov organic solvents kim dua, uas ua rau tus nqi tag nrho qis dua li cov txheej txheem ntxuav ntub ib txwm muaj; Xya, kev siv plasma ntxuav, zam kev thauj mus los, khaws cia, tso tawm thiab lwm yam kev kho mob ntawm cov kua ntxuav, yog li qhov chaw tsim khoom yooj yim kom huv thiab huv; Yim, kev ntxuav plasma tuaj yeem ua tau txawm tias kho cov khoom, nws tuaj yeem ua haujlwm nrog ntau yam khoom siv, txawm tias hlau, semiconductor, oxide, lossis cov ntaub ntawv polymer (xws li polypropylene, polyvinyl chloride, polytetrafluoroethylene, polyimide, polyester, epoxy resin thiab lwm yam polymers) tuaj yeem siv los ua haujlwm nrog plasma. Yog li ntawd, nws yog qhov tshwj xeeb tshaj yog rau cov ntaub ntawv uas tsis tiv taus cua sov thiab tiv taus cov kuab tshuaj. Nws kuj tseem tuaj yeem xaiv ntxuav tag nrho, ib feem lossis cov qauv nyuaj ntawm cov khoom siv; Cuaj, thaum ua tiav kev ntxuav kom huv tib lub sijhawm, kuj tseem tuaj yeem txhim kho qhov ua tau zoo ntawm cov khoom siv nws tus kheej. Xws li txhim kho qhov ntub dej ntawm qhov chaw, txhim kho qhov nplaum ntawm zaj duab xis, thiab lwm yam, uas yog qhov tseem ceeb heev rau ntau daim ntawv thov.
