Incazelo yokulinganisa

IukulevelishaImpahla yengubo ichazwa njengekhono lengubo lokugeleza ngemva kokusetshenziswa, ngaleyo ndlela kukhulisa ukususwa kwanoma yikuphi ukungalingani kwendawo okubangelwa inqubo yokufaka. Ngokuqondile, ngemva kokusetshenziswa kwengubo, kuba nenqubo yokugeleza nokomisa, bese kwakheka ifilimu yengubo eyisicaba, ebushelelezi, nefanayo kancane kancane. Ukuthi ingubo ingafinyelela yini imfanelo eyisicaba nebushelelezi kubizwa ngokuthi ukulevelisha.

Ukuhamba kokumbozwa okumanzi kungachazwa ngamamodeli amathathu:

① imodeli ye-angle yokuxhumana nokugeleza esakazekayo ku-substrate;

② imodeli ye-sine wave yokugeleza kusuka ebusweni obungalingani kuya ebusweni obuyisicaba;

③ I-Benard vortex iqonde phezulu. Ihambisana nezigaba ezintathu eziyinhloko zokulinganisa ifilimu emanzi - ukusabalala, ukulinganisa kwasekuqaleni nasekupheleni, lapho ukucindezeleka kobuso, amandla okusika, ushintsho lwe-viscosity, i-solvent nezinye izinto zidlala indima ebalulekile esigabeni ngasinye.

Ukusebenza okuphansi kokulinganisa

(1) Izimbobo zokuncipha
Kukhona izinto eziphansi zokucindezeleka kobuso (imithombo yemigodi yokuncipha) efilimini yokumboza, ezinomehluko wokucindezeleka kobuso nengubo ezungezile. Lo mehluko ukhuthaza ukwakheka kwemigodi yokuncipha, okubangela ukuthi uketshezi oluzungezile lugeleze lusuke kulo bese lwenza umgodi.

(2) Ikhasi le-orenji
Ngemva kokoma, ubuso bengubo bubonisa ukuvela okuningi okungalingani, okufana nokuqhekeka kwesikhumba se-orange. Lesi simo sibizwa ngokuthi isikhumba se-orange.

(3) Ukuwa
Ifilimu yokumboza emanzi iqhutshwa amandla adonsela phansi ukuze yakhe izimpawu zokugeleza, okubizwa ngokuthi ukugoba.

Izici ezithinta ukulevelishwa

(1) Umphumela wokucindezelwa kobuso obumbozwayo ekulinganisweni.
Ngemva kokusetshenziswa kwesembozo, kuzovela izixhumi ezintsha: isixhumi esiwuketshezi/esiqinile phakathi kwesembozo kanye nesendlalelo kanye nesixhumi esiwuketshezi/esigesi phakathi kwesembozo nomoya. Uma ukungezwani kokuxhumana kwesixhumi esiwuketshezi/esiqinile phakathi kwesembozo kanye nesendlalelo kuphakeme kunokucindezeleka okubalulekile kobuso besendlalelo, isembozo ngeke sikwazi ukusabalala ku-sendlalelo, futhi amaphutha okulinganisa njengokuncipha, imigodi yokuncipha, kanye nama-fisheye kuzokwenzeka ngokwemvelo.

(2) Umphumela wokuncibilika ekulinganisweni.
Ngesikhathi senqubo yokomisa ifilimu yopende, ezinye izinhlayiya ezinganyibiliki ngezinye izikhathi ziyakhiqizwa, okuthi kamuva zakhe i-gradient yokucindezeleka kobuso futhi kuholele ekwakhekeni kwezimbobo zokuncipha. Ngaphezu kwalokho, ekwakhiweni okuqukethe ama-surfactants, uma i-surfactant ingahambisani nohlelo, noma ngesikhathi senqubo yokomisa, njengoba i-solvent ihwamuka, ukuhlushwa kwayo kuyashintsha, okuholela ekushintsheni kokuncibilika, kwakha amaconsi angavumelani, futhi kwakha umehluko wokucindezeleka kobuso. Lokhu kungaholela ekwakhekeni kwezimbobo zokuncipha.

(3) Umphumela wobukhulu befilimu emanzi kanye nokwehla kokuqina kobuso ekulinganisweni.
I-Benard vortex – Ukuhwamuka kwe-solvent ngesikhathi senqubo yokomisa ifilimu yopende kuzokhiqiza umehluko wokushisa, ubuningi kanye nokungezwani kobuso phakathi kobuso kanye nengaphakathi lefilimu yopende. Lokhu kungafani kuzoholela ekuhambeni okuguquguqukayo ngaphakathi kwefilimu yopende, kwakha okuthiwa i-Benard vortex. Izinkinga zefilimu yopende ezibangelwa ama-vortices e-Benard aziwona nje ama-peel e-orange. Ezinhlelweni eziqukethe i-pigment engaphezu kweyodwa, uma kukhona umehluko othile ekuhambeni kwezinhlayiya ze-pigment, ama-vortices e-Benard cishe angabangela ukuntanta nokuqhakaza, futhi ukusetshenziswa kwendawo eqondile nakho kuzobangela imigqa yesilika.

(4) Umphumela wobuchwepheshe bokwakha kanye nendawo ekulinganisweni.
Ngesikhathi senqubo yokwakha nokwakha ifilimu yengubo, uma kukhona ukungcola kwangaphandle, kungase kubangele nokukhubazeka kokuleveli njengemigodi yokuncibilika kanye namehlo enhlanzi. Lokhu kungcola kuvame ukuvela ku-oyili, uthuli, inkungu yopende, umhwamuko wamanzi, njll. ovela emoyeni, amathuluzi okwakha kanye nezingxenye ezingaphansi komhlaba. Izakhiwo zengubo ngokwayo (njengokunamathela kokwakha, isikhathi sokomisa, njll.) nazo zizoba nomthelela omkhulu ekulinganisweni kokugcina kwefilimu yopende. Ukunamathela kokwakha okuphezulu kakhulu kanye nesikhathi esifushane kakhulu sokomisa ngokuvamile kuveza ukubukeka okulinganiselwe kahle.

Izinto Ezintsha Ezintsha zaseNanjing zinikezaama-ejenti okulevelishakufaka phakathi i-Organo Silicone kanye ne-Non-silicon ezihambisana ne-BYK.
