imikhiqizo

impahla yamakhemikhali

Ngokwesakhiwo samakhemikhali esihlukene, lolu hlobo lwe-ejenti yokulinganisa lunezigaba ezintathu eziyinhloko: i-acrylic acid, i-organic silicon kanye ne-fluorocarbon. I-ejenti yokulinganisa iyi-ejenti yokulinganisa esetshenziswa kakhulu, engenza ukwakheka kwe-ejenti kube ifilimu ebushelelezi, ebushelelezi futhi efanayo enkambisweni yokomisa. Inganciphisa ngempumelelo ukungezwani kobuso be-ejenti yokuhlanganisa, ithuthukise ukulingana kwayo kanye nokufana kwesigaba sezinto. Ingathuthukisa ukungena kwesisombululo sokuqeda, inciphise amathuba okuba namabala kanye nezimpawu lapho ixubha, yandise ukumbozwa, futhi yenze ifilimu ifane futhi ibe yendalo. Ngokuyinhloko ama-surfactants, ama-organic solvents njalo njalo. Kunezinhlobo eziningi ze-ejenti yokulinganisa, futhi izinhlobo ze-ejenti yokulinganisa ezisetshenziswa ezimbozweni ezahlukene azifani. Ama-solvent aphezulu abilayo noma i-butyl cellulose angasetshenziswa ekuqedeni okusekelwe ku-solvent. E-ejenti yokuqeda esekelwe emanzini ene-surfactants noma i-polyacrylic acid, i-carboxymethyl cellulose

Isingeniso somkhiqizo kanye nezici

Ama-leveling agents ahlukaniswe kabanzi ngezigaba ezimbili. Esinye siwukulungisa i-viscosity yefilimu kanye nesikhathi sokulinganisa ukusebenza, lolu hlobo lwe-leveling agent luvame ukuba yizinyibilikisi noma izingxube zezinto eziphilayo ezibilayo eziphakeme, njenge-isoporone, i-diacetone alcohol, i-Solvesso150; Esinye siwukulungisa izakhiwo zomphezulu wefilimu ukuze zisebenze, abantu abavamile bathi i-leveling agent ibhekisela kakhulu kulolu hlobo lwe-leveling agent. Lolu hlobo lwe-LEVELING AGENT luthuthela ebusweni befilimu ngokusebenzisa ukuhambisana okulinganiselwe, luthinta izakhiwo zomphezulu wefilimu njengokucindezeleka kwe-INTERfacial, futhi lwenze ifilimu ithole i-leveling enhle.

sebenzisa

Umsebenzi oyinhloko wokumboza ukuhlobisa nokuvikela, uma kukhona amaphutha okugeleza nokulinganisa, akuthinti nje kuphela ukubukeka, kodwa futhi kulimaze umsebenzi wokuvikela. Njengokwakheka kokuncipha okubangelwa ukujiya kwefilimu akwanele, ukwakheka kwemigodi kuzoholela ekungaqhubeki kwefilimu, lokhu kuzonciphisa ukuvikelwa kwefilimu. Enkambisweni yokwakhiwa kokumboza nokwakheka kwefilimu, kuzoba nezinguquko ezithile zomzimba nezamakhemikhali, lezi zinguquko kanye nohlobo lokumboza ngokwalo, kuzothinta kakhulu ukugeleza nokulinganisa kokumboza.
Ngemva kokusetshenziswa kwesembozo, kuzovela izixhumi ezintsha, ngokuvamile isixhumi esiwuketshezi/esiqinile phakathi kwesembozo kanye nesendlalelo kanye nesixhumi esiwuketshezi/esigesi phakathi kwesembozo nomoya. Uma ukungezwani kwe-INTERfacial OF THE liquid/esiqinile isixhumi esiphakathi kwesembozo kanye nesendlalelo kuphakeme kunokuqina okubalulekile kobuso besendlalelo, isembozo ngeke sikwazi ukusabalala ku-substrate, okuzokhiqiza ngokwemvelo amaphutha okulevelisha njengemigodi ye-fisheye kanye nokuncibilika.
UKUHLUKA KWESIXULULWA NGESIKHATHI SENQUBO YOKUMISA ifilimu kuzoholela ekuhlukeni kwezinga lokushisa, ubuningi kanye nokucindezeleka kobuso phakathi kobuso kanye nengaphakathi lefilimu. Lokhu kuhluka kuholela ekunyakazeni okuguquguqukayo ngaphakathi kwefilimu, kwakha okuthiwa i-vortex ye-Benard. I-vortex ye-Benard iholela emakhasini e-orange; Ezinhlelweni ezine-pigment engaphezu kweyodwa, uma kukhona umehluko othile ekuhambeni kwezinhlayiya ze-pigment, i-vortex ye-Benard nayo kungenzeka iholele embala ontantayo nasezinweleni, futhi ukwakheka okuqondile kuzoholela emigqeni yesilika.
INQUBO YOKUMISA YEFILIMU YEPEYINTI NGESINYE ISIKHATHI IKHIQIZA IZINHLAMVU EZITHILE ZE-COLLOIDAL EZINGACACILE, UKUKHIQIZWA KWEZINHLAMVU ZE-COLLOIDAL EZINGACACILE kuzoholela ekwakhekeni kwe-gradient yokucindezeleka kobuso, okuvame ukuholela ekukhiqizweni kwezimbobo zokuncipha efilimini yopende. ISIBONELO, ESIHLELWENI SOKUQINISEKISA ESIXHUMENE NEZINHLANGANO, LAPHO ukwakheka kuqukethe i-RESIN EPHEZU KWEYODWA, i-resin encibilikayo kancane ingakha izinhlayiya ze-colloidal ezingancibiliki njengoba uketshezi lushintsha ngesikhathi senqubo yokomisa ifilimu yopende. Ngaphezu kwalokho, ekwakhiweni okuqukethe i-surfactant, uma i-surfactant ingahambisani nesistimu, noma enqubweni yokomisa ngokuguquguquka kwe-solvent, izinguquko zokuhlushwa kwayo ziholela ekushintsheni kokuncibilika, ukwakheka kwamaconsi angahambisani, kuzokwakha nokucindezeleka kobuso. Lokhu kungaholela ekwakhekeni kwezimbobo zokuncipha.
Enkambisweni yokwakhiwa kwe-coating kanye nokwakheka kwefilimu, uma kukhona ukungcola kwangaphandle, kungase kuholele nasekuncipheni kwembobo, i-fisheye kanye nezinye izinkinga zokulinganisa. Lokhu kungcola kuvame ukuvela emoyeni, amathuluzi okwakha kanye namafutha e-substrate, uthuli, inkungu yopende, umhwamuko wamanzi, njll.
Izakhiwo zopende ngokwawo, njengokuthambeka kokwakhiwa, isikhathi sokomisa, njll., nazo zizoba nomthelela omkhulu ekulinganisweni kokugcina kwefilimu yopende. Ukuthambeka okuphezulu kakhulu kokwakhiwa kanye nesikhathi esifushane sokomisa ngokuvamile kuzodala indawo yokuthambeka engeyinhle.
Ngakho-ke, kuyadingeka ukwengeza i-ejenti yokulengisa, ngokusebenzisa i-coating enqubweni yokwakha kanye nokwakheka kwefilimu yezinguquko ezithile kanye nezakhiwo zokulengisa ukuze kulungiswe, ukusiza upende uthole i-leveling enhle.

iphakheji kanye nokuthuthwa

B. Lo mkhiqizo ungasetshenziswa, 25KG, 200KG, 1000KG BARRELS.
C. Gcina kuvaliwe endaweni epholile, eyomile futhi enomoya opholile ngaphakathi. Izitsha kufanele zivalwe kahle ngemva kokusetshenziswa ngakunye ngaphambi kokusetshenziswa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuthuthwa ukuze kuvinjelwe umswakama, i-alkali enamandla ne-asidi, imvula nokunye ukungcola ekuxubeni.
