1. Izinga lokuphuma komphunga liya kuchaphazela iimpawu zokwaleka komphunga
Izinga lokuphuma komoya linempembelelo enkulu kwifilimu egciniweyo. Ngenxa yokuba isakhiwo sokugquma esenziwe ngesantya esiphantsi sokufumba sikhululekile kwaye kulula ukuvelisa ukufumba okukhulu kwamasuntswana, kukhuselekile kakhulu ukukhetha izinga eliphezulu lokuphuma komoya ukuqinisekisa ubuncinci besakhiwo sokufumba. Xa uxinzelelo lwegesi eseleyo kwigumbi lokufumba luhlala luhleli, izinga lokuqhushumba kwe-substrate lixabiso elingaguqukiyo. Ke ngoko, igesi eseleyo equlethwe kwifilimu egciniweyo emva kokukhetha izinga eliphezulu lokufumba liya kuncitshiswa, ngaloo ndlela kunciphisa impendulo yekhemikhali phakathi kweemolekyuli zegesi eziseleyo kunye namasuntswana efilimu ephumayo. Ke ngoko, ubunyulu befilimu egciniweyo bunokuphuculwa. Kufuneka kuqatshelwe ukuba ukuba izinga lokufumba likhawuleza kakhulu, linokunyusa uxinzelelo lwangaphakathi lwefilimu, liya kwanda iziphene kwifilimu, kwaye lide likhokelele ekuqhekekeni kwefilimu. Ngokukodwa, kwinkqubo yokufumba okusebenzayo kokufuma, ukuze igesi yokusabela iphendule ngokupheleleyo ngamasuntswana efilimu yokufuma, ungakhetha izinga eliphantsi lokufumba. Kakade ke, izinto ezahlukeneyo zikhetha amazinga ahlukeneyo okuphuma komoya. Njengomzekelo osebenzayo – ukubekelwa kwefilimu ebonakalisa ukukhanya, Ukuba ubukhulu befilimu buyi-600×10-8cm kwaye ixesha lokuphuma komoya liyi-3s, ukubekelwa kwembonakalo yi-93%. Nangona kunjalo, ukuba izinga lokuphuma komoya liyehla phantsi kwemeko efanayo yobukhulu, kuthatha imizuzu eli-10 ukugqiba ukubekelwa kwefilimu. Ngeli xesha, ubukhulu befilimu buyafana. Nangona kunjalo, ukubekelwa kwembonakalo kwehle ukuya kwi-68%.
2. Ubushushu bokuhlisa buya kuchaphazela ukugquma komphunga
Ubushushu be-substrate bunempembelelo enkulu kwi-evaporation coating. Ii-molecules zegesi eziseleyo ezifakwe kumphezulu we-substrate kubushushu obuphezulu be-substrate kulula ukuzisusa. Ingakumbi ukususwa kwee-molecules zomphunga wamanzi kubaluleke ngakumbi. Ngaphezu koko, kubushushu obuphezulu, akulula nje ukukhuthaza utshintsho ukusuka kwi-physical adsorption ukuya kwi-chemical adsorption, ngaloo ndlela kwandisa amandla okubopha phakathi kwamasuntswana. Ngaphezu koko, kunokunciphisa umahluko phakathi kobushushu be-recrystallization yee-molecules zomphunga kunye nobushushu be-substrate, ngaloo ndlela kunciphisa okanye kususe uxinzelelo lwangaphakathi kwi-interface esekelwe kwifilimu. Ukongeza, ngenxa yokuba ubushushu be-substrate bunxulumene nemeko ye-crystalline yefilimu, kudla ngokuba lula ukwenza ii-amorphous okanye microcrystalline coatings phantsi kwemeko yobushushu obuphantsi be-substrate okanye ukungabikho kobushushu. Ngokwahlukileyo koko, xa ubushushu buphezulu, kulula ukwenza i-crystalline coating. Ukunyusa ubushushu be-substrate kukwanceda ekuphuculeni iipropati zoomatshini ze-coating. Kakade ke, ubushushu be-substrate akufuneki bube phezulu kakhulu ukuthintela ukufuma kwe-coating.
3. Uxinzelelo lwegesi oluseleyo kwigumbi lokucoca umoya luya kuchaphazela iimpawu zefilimu
Uxinzelelo lwegesi eseleyo kwigumbi lokuphuma umoya lunempembelelo enkulu ekusebenzeni kwe-membrane. Iimolekyuli zegesi eseleyo ezinoxinzelelo oluphezulu kakhulu azilula nje ukungqubana namasuntswana aphumayo, nto leyo eya kunciphisa amandla e-kinetic abantu abakwi-substrate kwaye ichaphazele ukunamathela kwefilimu. Ukongeza, uxinzelelo lwegesi eseleyo oluphezulu kakhulu luya kuchaphazela kakhulu ubunyulu befilimu kwaye lunciphise ukusebenza kwengubo.
4. Impembelelo yobushushu bokufuma kwi-evaporation coating
Impembelelo yobushushu bokufuma ekusebenzeni kwe-membrane iboniswa kukutshintsha kwesantya sokufudumala kunye nobushushu. Xa ubushushu bokufuma buphezulu, ubushushu bokufuma buya kuncipha. Ukuba izinto ze-membrane ziphuma emoyeni ngaphezu kobushushu bokufuma, nokuba utshintsho oluncinci kubushushu lunokubangela utshintsho olubukhali kwisantya sokufudumala kwezinto ze-membrane. Ke ngoko, kubaluleke kakhulu ukulawula ubushushu bokufuma ngokuchanekileyo ngexesha lokufakwa kwefilimu ukuze kuthintelwe i-gradient enkulu yobushushu xa umthombo wokufuma ushushu. Kwizinto zefilimu ezilula ukuzisusa, kubaluleke kakhulu ukukhetha izinto ngokwazo njengesifudumezi sokufuma kunye nezinye iindlela.
5. Ukucoca imeko ye-substrate kunye negumbi lokugquma kuya kuchaphazela ukusebenza kokugquma
Impembelelo yokucoceka kwe-substrate kunye negumbi lokugquma ekusebenzeni kwengubo ayinakutyeshelwa. Ayizukuchaphazela kakhulu ubunyulu befilimu egciniweyo kuphela, kodwa iya kunciphisa nokunamathela kwefilimu. Ke ngoko, ukucocwa kwe-substrate, unyango lokucoca igumbi lokugquma nge-vacuum kunye nezinto ezinxulumene nayo (ezifana nesakhelo se-substrate) kunye nokususwa kwegesi kumphezulu zonke ziinkqubo eziyimfuneko kwinkqubo yokugquma nge-vacuum.
