Ukuhlaziywa kokwakhiwa kwe-coating

I-Hydroxyethyl Cellulose Ether

IHydroxyethyl cellulose ether, into esebenzayo engeyona i-ionic, iyisigqinsi se-cellulose ether esekwe emanzini esekwe emanzini. Kuyinhlanganisela engeyona i-ionic encibilika emanzini futhi inekhono elihle lokujiya emanzini.

Inezici eziningi ezinjengokuqina, ukuntanta, ukubopha, ukufaka i-emulsifying, ukwenza ifilimu, ukugxilisa ingqondo, ukuvikela amanzi ekuhwamukeni, ukuthola nokuqinisekisa umsebenzi wezinhlayiya, futhi inezici eziningi ezikhethekile.

Ukuhlakazeka

I-disperant i-surfactant enezici ezimbili eziphambene ze-lipophilicity kanye ne-hydrophilicity ku-molecule. Ingakwazi ukuhlakaza ngokufanayo izinhlayiya eziqinile neziwuketshezi zemibala ye-inorganic kanye ne-organic okunzima ukuyincibilikisa oketshezini, futhi ngesikhathi esifanayo ivimbele izinhlayiya ukuthi zingahlali futhi zihlangane, zenze i-amphiphilic agent edingekayo ukuze kumiswe ukumiswa okuzinzile.

Nge-dispersant, ingakwazi ukuthuthukisa ukucwebezela, ivimbele umbala ontantayo, futhi ithuthukise amandla okuthayela. Qaphela ukuthi amandla okufaka umbala awekho phezulu ngangokunokwenzeka ohlelweni lombala oluzenzakalelayo, ukunciphisa i-viscosity, ukwandisa ukulayishwa kwezingulube, njll.

I-ejenti yokumanzisa

I-ejenti yokumanzisa idlala indima ehamba phambili ohlelweni lokumboza, olungafinyelela ebusweni be-substrate kuqala ukuze "uvule umgwaqo", bese into eyenza ifilimu ingasakazwa "emgwaqweni" ohanjwe yi-ejenti yokumanzisa. Kuhlelo olusekelwe emanzini, i-ejenti yokumanzisa ibaluleke kakhulu, ngoba ukungezwani kwamanzi kuphezulu kakhulu, kufinyelela kuma-dynes angu-72, okuphakeme kakhulu kunokucindezeleka kwendawo ye-substrate. Spread flow.

I-ejenti ye-Antifoaming

I-Defoamer ibizwa nangokuthi i-defoamer, i-antifoaming ejenti, ne-ejenti egwebu empeleni isho ukuqeda igwebu. Kuyinto enokushuba okuphansi kwendawo kanye nomsebenzi ophezulu, ongacindezela noma uqede igwebu ohlelweni. Amagwebu amaningi ayingozi azokhiqizwa ohlelweni lokukhiqiza ezimbonini, okuphazamisa kakhulu ukuqhubeka kokukhiqiza. Ngalesi sikhathi, kuyadingeka ukwengeza i-defoamer ukuze kuqedwe lawa magwebu ayingozi.

I-Titanium dioxide

Imboni kapende ingumsebenzisi omkhulu we-titanium dioxide, ikakhulukazi i-rutile titanium dioxide, iningi layo elisetshenziswa imboni kapende. Upende owenziwe nge-titanium dioxide unemibala egqamile, amandla aphakeme okufihla, amandla aqinile okuthayela, umthamo ophansi, nezinhlobonhlobo eziningi. Ingavikela ukuzinza kwe-medium, futhi ingathuthukisa amandla emishini nokunamathela kwefilimu kapende ukuvimbela imifantu. Ivimbela imisebe ye-UV kanye nomswakama ukuthi ungangeni, andise impilo yefilimu kapende.

I-Kaolin

I-Kaolin iwuhlobo lokugcwalisa. Uma isetshenziselwa ukugqoka, imisebenzi yayo eyinhloko yilezi: ukugcwalisa, ukwandisa ubukhulu befilimu yepende, okwenza ifilimu yepende ibe yinkimbinkimbi futhi iqinile; ukuthuthukisa ukumelana nokugqoka nokuqina; ukulungisa izakhiwo ze-optical zokugqoka, ukushintsha Ukubukeka kwefilimu yokugqoka; njenge-filler e-coating, inganciphisa inani le-resin esetshenzisiwe futhi inciphise izindleko zokukhiqiza; idlala indima eyisiqondiso kumakhemikhali efilimu yokumboza, njengokuthuthukisa ukulwa nokugqwala kanye nokuncipha komlilo.

i-calcium eningi

Uma i-calcium enzima isetshenziswa kumapende wezakhiwo zangaphakathi, ingasetshenziswa iyodwa noma ihlanganiswe ne-talcum powder. Uma kuqhathaniswa ne-talc, i-calcium enzima inganciphisa izinga lokusho, ithuthukise ukugcinwa kombala wamapende anombala okhanyayo futhi yandise ukumelana nesikhunta.

Lotion

Indima ye-emulsion ukumboza i-pigment kanye ne-filler ngemva kokwakhiwa kwefilimu (i-powder enekhono elinamandla lombala i-pigment, futhi i-powder ngaphandle kwekhono lombala i-filler) ukuvimbela ukukhishwa kwe-powder. Ngokuvamile, i-styrene-acrylic emulsion ehlanzekile isetshenziselwa izindonga zangaphandle. I-styrene-acrylic iyabiza, izoba phuzi, i-acrylic ehlanzekile inokumelana nesimo sezulu esihle nokugcinwa kombala, futhi intengo iphakeme kancane. Opende bodonga bangaphandle bezinga eliphansi ngokuvamile basebenzisa ama-emulsion we-styrene-acrylic, futhi opende bodonga bangaphandle abaphakathi ukuya phezulu ngokuvamile basebenzisa ama-emulsions e-acrylic ahlanzekile.

Fingqa

Ekukhiqizeni izigqoko, izinto eziwusizo ezisebenzayo ezifana nama-preservatives kanye nama-thickeners nazo zengezwa.

Okungenhla ukuhlaziya ukwakheka kwezinto zokusetshenziswa zopende. Ngokuthuthuka okuqhubekayo komnotho, izidingo zabantu zokumboza nazo zishintsha njalo. Kuzoba nezimanga eziningi ezisilindile emakethe kapende yesikhathi esizayo!
