Inkcazo yokulinganisa

IukulenzaIpropathi yokwambathisa ichazwa njengamandla okwambathisa ukuba kuhambe emva kokusetyenziswa, ngaloo ndlela kunciphisa ukungalingani komphezulu okubangelwa yinkqubo yokusetyenziswa. Ngokukodwa, emva kokuba kwambathisa, kukho inkqubo yokuhamba nokomisa, kwaye emva koko kwenziwa ifilimu yokugquma ethe tyaba, egudileyo, nefanayo kancinci kancinci. Ukuba kwambathisa kungafikelela kwipropathi ethe tyaba negudileyo kubizwa ngokuba kukulinganisa.

Intshukumo yokwaleka okumanzi ingachazwa ziimodeli ezintathu:

① imodeli ye-engile yokunxibelelana nokuhamba komoya kwi-substrate;

② imodeli ye-sine wave yokuhamba ukusuka kumphezulu ongalinganiyo ukuya kumphezulu othe tyaba;

③ I-Benard vortex kwicala elithe nkqo. Zihambelana namanqanaba amathathu aphambili okulinganisa ifilimu emanzi - ukusasazeka, ukulinganisa kwangoko nasekupheleni, apho uxinzelelo lomphezulu, amandla okucheba, utshintsho lwe-viscosity, isinyibilikisi kunye nezinye izinto zidlala indima ebalulekileyo kwinqanaba ngalinye.

Ukusebenza kakubi kokulinganisa

(1) Imingxunya yokuncipha
Kukho izinto eziphantsi zoxinzelelo lomphezulu (imithombo yemingxunya yokushwabana) kwifilimu yokugquma, ezinomahluko woxinzelelo lomphezulu xa kuthelekiswa nophawu olujikelezileyo. Lo mahluko ukhuthaza ukwakheka kwemingxunya yokushwabana, nto leyo ebangela ukuba ulwelo olujikelezileyo luphume kulo luze lwenze uxinano.

(2) Ixolo leorenji
Emva kokoma, umphezulu wengubo ubonisa iinxalenye ezininzi ezimile okwesiyingi, ezifana neempumlo zexolo le-orenji. Le nto ibizwa ngokuba lixolo le-orenji.

(3) Ukuwa
Ifilimu emanzi egqumayo iqhutywa ngumxhuzulane ukuze yenze iimpawu zokuhamba kwamanzi, ezibizwa ngokuba yi-sagging.

Izinto ezichaphazela ukulenza inqanaba

(1) Impembelelo yoxinzelelo lomphezulu wokugquma ekulinganiseni.
Emva kokusetyenziswa kwengubo, kuza kuvela iindlela ezintsha zokunxibelelana: ulwelo/ulwelo oluqinileyo phakathi kwengubo kunye ne-substrate kunye nolwelo/ulwelo/igesi phakathi kwengubo kunye nomoya. Ukuba uxinzelelo lwe-interfacial lwe-interface ye-liquid/ulwelo oluqinileyo phakathi kwengubo kunye ne-substrate luphezulu kunoxinzelelo olubalulekileyo lomphezulu we-substrate, ingubo ayizukukwazi ukusasazeka kwi-substrate, kwaye iziphene zokulinganisa ezifana nokuncipha, imingxunya yokuncipha, kunye namabala eentlanzi ziya kwenzeka ngokwemvelo.

(2) Isiphumo sokunyibilika ekulinganiseni.
Ngexesha lenkqubo yokomisa ifilimu yepeyinti, ngamanye amaxesha kuveliswa amasuntswana anganyibilikiyo, nto leyo eyenza i-surface tension gradient kwaye ikhokelele ekwakhekeni kwemingxuma yokuncitshiswa. Ukongeza, kwifomyula equlethe ii-surfactants, ukuba i-surfactant ayihambelani nenkqubo, okanye ngexesha lenkqubo yokomisa, njengoko i-solvent iphuma, uxinzelelo lwayo luyatshintsha, nto leyo ebangela utshintsho ekunyibilikeni, ukwenza amaconsi angahambelaniyo, kunye nokwenza umahluko woxinzelelo lomphezulu. Oku kunokukhokelela ekwakhekeni kwemingxuma yokuncitshiswa.

(3) Isiphumo sobukhulu befilimu emanzi kunye ne-gradient yoxinzelelo lomphezulu ekulinganiseni.
I-Benard vortex – Ukufuma kwe-solvent ngexesha lenkqubo yokomisa ifilimu yepeyinti kuya kuvelisa umahluko phakathi kobushushu, uxinano kunye noxinzelelo lomphezulu phakathi komphezulu kunye nangaphakathi kwefilimu yepeyinti. Olu mahluko luya kukhokelela kwintshukumo eguquguqukayo ngaphakathi kwefilimu yepeyinti, nto leyo ebizwa ngokuba yi-Benard vortex. Iingxaki zefilimu yepeyinti ezibangelwa zii-vortices zeBenard azingoorenji kuphela. Kwiinkqubo eziqulethe imibala engaphezulu kwesinye, ukuba kukho umahluko othile ekuhambeni kwee-pigment particles, ii-vortices zeBenard zinokubangela ukudada nokuqhakaza, kwaye ukusetyenziswa komphezulu ngokuthe nkqo kuya kubangela imigca yesilika.

(4) Impembelelo yetekhnoloji yokwakha kunye nokusingqongileyo ekulinganiseni.
Ngexesha lenkqubo yokwakha nokwenza ifilimu yokwambathisa, ukuba kukho ungcoliseko lwangaphandle, lunokubangela iziphene zokungaguquguquki ezifana nemingxunya yokuncibilika kunye namehlo eentlanzi. Ezi zingcoliseko zihlala zivela kwioyile, uthuli, inkungu yepeyinti, umphunga wamanzi, njl.njl. ovela emoyeni, kwizixhobo zokwakha nakwizinto ezisetyenziswayo. Iimpawu zokwambathisa ngokwazo (ezifana nokungunda kokwakha, ixesha lokomisa, njl.njl.) nazo ziya kuba nefuthe elikhulu ekulinganisweni kokugqibela kwefilimu yokupenda. Ukungunda kokwakha okuphezulu kakhulu kunye nexesha elifutshane kakhulu lokomisa zihlala zivelisa imbonakalo engalinganiyo.
