Izimiso zama-ejenti okulinganisa

Ukubuka konke Kwezinga .

Ngemuva kokusetshenziswa kwezingubo zokugqoka, kunenqubo yokugeleza nokomisa ibe yifilimu, kancane kancane yakha ukugqoka okubushelelezi, okulinganayo, nokufana. Ikhono lokumboza ukuze kuzuzwe indawo eyisicaba futhi ebushelelezi kubizwa ngokuthi yimpahla yokulinganisa.

Ezinhlelweni zokugqoka ezisebenzayo, ukukhubazeka okuvamile okufana nekhasi lewolintshi, amehlo ezinhlanzi , izimbobo, imigodi eshwabene, ukuhlehla komphetho, ukuzwela kokugeleza komoya, kanye nezimpawu zebhulashi phakathi nezimpawu zokuxubha namarola ngesikhathi sokufakwa kwe-roller-konke kubangelwa izinga eliphansi-sezizonke zibizwa ngokuthi izinga eliphansi . Lezi zenzakalo zilulaza imisebenzi yokuhlobisa neyokuvikela ye-coating.

Kunezici eziningi ezithonya izinga le-coating, okuhlanganisa ukuhwamuka kwe-solvent gradient kanye nokuncibilika, ukushuba kwento enamathelayo, ukushuba kwefilimu emanzi kanye ne-surface gradient, izakhiwo ze-rheological ze-coating.,amasu okusebenza, nezimo zemvelo. Phakathi kwalokhu, izici ezibucayi kakhulu ukushuba kwengaphezulu kwento enamathelayo, i-surface tension gradient eyakhiwe efilimini emanzi ngesikhathi kwakhiwa ifilimu, kanye.ikhono lefilimu elimanzi ukulinganisa ukungezwani kwendawo.

Ukuthuthukisa izinga le-coating kudinga ukulungisa ukwakheka kanye nokuhlanganisa izithasiselo ezifanele ukuze kuzuzwe ukushuba kwendawo efanele futhi kuncishiswe ukungezwani okungaphezulu.

Umsebenzi we-Leveling Agents

I-ejenti yokulinganisan iyisengezo esilawula ukugeleza kwento enamathelayo ngemva kokumanzisa i-substrate, iyiqondise ekuqedeni okubushelelezi, kokugcina. Ama-level agents abhekana nalezi zinkinga ezilandelayo:

I-Surface Tension Gradient-I-Air Interface

Isiyaluyalu esibangelwa ama-gradients aqinile phakathi kwezendlalelo zangaphakathi nezingaphandle.Ukuqeda i-high tension gradients kubalulekile ukuze kuzuzwe indawo ebushelelezi

I-Surface Tension Gradient-I-Substrate Interface

Ukushuba kwesimo esiphansi kune-substrate kuthuthukisa ukumanzisa kwe-substrate

Ukunciphisa enamathela's ukungezwani kwendawo kunciphisa ukukhangana kwama-intermolecular endaweni, kukhuthaze ukugeleza okungcono

Izinto Ezithinta Isivinini Sokulinganisa

I-viscosity ephakeme→ukwehlisa izinga

Amafilimu ashubile→leveling ngokushesha

Ukushuba okuphezulu kwendawo→leveling ngokushesha
