Iyini inqubo ye-Dip Coating

Enkambweni yokugqoka i-dip, i-substrate icwiliswa kwisisombululo se-liquid coating bese ihoxiswa kwisisombululo ngesivinini esilawulwayo. Ufuzo ukujiya enamathelaralinyuka ngesivinini sokuhoxa ngokushesha. Ubukhulu bunqunywa ibhalansi yamandla endaweni yokuma endaweni ewuketshezi. Isivinini sokuhoxa esisheshayo sidonsa uketshezi olwengeziwe phezulu phezu kwe-substrate ngaphambi kokuba sibe nesikhathi sokugeleza sibuyele esixazululweni. Ugqinsi luthintwa ngokuyinhloko yi-viscosity ye-fluid, ukuminyana koketshezi, nokushuba kwendawo.
Ukulungiswa kwe-waveguide nge-dip-coating technique kungahlukaniswa ngezigaba ezine:

1. Ukulungiswa noma ukukhetha kwe-substrate;
2. Ukubekwa kwezendlalelo ezizacile;
3. Ukwakhiwa kwefilimu;
4. Ukuminyana kulo lonke ukwelashwa okushisayo.

I-Dip coating, ngenkathi ihle kakhulu ekukhiqizeni izinga eliphezulu, i-uniform coatings, idinga ukulawula okunembile kanye nendawo ehlanzekile. I-coating esetshenzisiwe ingase ihlale imanzi izikhathi eziyisikhombisaral imizuzu kuze kube yilapho i-solvent iyahwamuka. Le nqubo ingasheshiswa ngokumisa okushisayo. Ngaphezu kwalokho, ukugqoka kungase kwelashwe ngezindlela ezihlukahlukene ezihlanganisa amasu avamile ashisayo, i-UV, noma i-IR kuye ngokwakhiwa kwesisombululo sokumboza. Uma ungqimba seselaphekile, esinye isendlalelo singasetshenziswa phezu kwaso nenye inqubo yokugcotshwa/yokwelapha. Ngale ndlela, kwakhiwa isitaki se-AR sezendlalelo eziningi.
