Igisobanuro cyo kuringaniza

UwitekakuringanizaUmutungo wikibiriti usobanurwa nkubushobozi bwigitambaro cyo gutembera nyuma yo kubisaba, bityo bikuraho cyane kurandura ubuso ubwo aribwo bwose buterwa nuburyo bwo gusaba. By'umwihariko, nyuma yo gutwikirwa, hashyizweho inzira yo gutemba no gukama, hanyuma hakabaho firime ya tekinike, yoroshye, kandi imwe. Niba igifuniko gishobora kugera kumitungo iringaniye kandi yoroshye byitwa kuringaniza.

Urujya n'uruza rwinshi rushobora gusobanurwa nuburyo butatu:

Gukwirakwiza imigezi-ihuza ingero kuri substrate;

Model sine yerekana urugero rwimigezi kuva hejuru yuburinganire kugeza hejuru;

Ort Benard vortex mu cyerekezo gihagaritse. Bihuye nibyiciro bitatu byingenzi byo kuringaniza firime - gukwirakwira, gutinda hakiri kare no gutinda, mugihe impagarara zubuso, imbaraga zogosha, ihinduka ryijimye, ibishishwa nibindi bintu bigira uruhare runini muri buri cyiciro.

Imikorere idahwitse

(1) Kugabanya umwobo
Hano haribintu byo hasi yubushyuhe (inkomoko yo kugabanuka) muri firime ya coating, bifite itandukaniro ryubusumbane bwubuso hamwe nigitambaro gikikije. Iri tandukaniro riteza imbere kwibumbira mu mwobo, bigatuma amazi akikije amazi atembera kure kandi bigatera kwiheba.

(2) Igishishwa cya orange
Nyuma yo gukama, hejuru yikibiriti yerekana ibice byinshi byizengurutse, bisa nkibishishwa byikibabi cya orange. Iyi phenomenon yitwa igishishwa cya orange.

(3) Guswera
Filime itwikiriwe neza itwarwa nuburemere kugirango ikore ibimenyetso bitemba, byitwa kugabanuka.

Ibintu bigira ingaruka kuringaniza

(1) Ingaruka zo gutwikira hejuru yuburinganire kurwego.
Nyuma yo gutwikira porogaramu, intera nshya izagaragara: isura ya fluide / ikomeye hagati ya coating na substrate hamwe na flux / gazi hagati ya coating hamwe nikirere. Niba impagarara zintera zamazi yimbere / zifatika hagati yikingirizo na substrate irenze hejuru yuburemere bukomeye bwubutaka bwa substrate, igifuniko ntikizashobora gukwirakwira kuri substrate, kandi inenge iringaniza nko kugabanuka, imyenge yo kugabanuka, hamwe nuburobyi bizaba bisanzwe.

(2) Ingaruka zo kwikemurira kuringaniza.
Mugihe cyo kumisha firime yamabara, uduce tumwe na tumwe tudashonga rimwe na rimwe havamo, ibyo bikaba bigizwe nuburinganire bwikigereranyo kandi biganisha kumyenge yo kugabanuka. Mubyongeyeho, mubisobanuro birimo surfactants, niba surfactant idahuye na sisitemu, cyangwa mugihe cyo kumisha, nkuko umusemburo ugenda uhinduka, intumbero yacyo ihinduka, bikavamo impinduka zo gukemuka, gukora ibitonyanga bidahuye, no gutandukanya itandukaniro ryubutaka. Ibi birashobora gutuma habaho imyobo yo kugabanuka.

(3) Ingaruka yubushyuhe bwa firime itose hamwe nuburinganire bwurwego rwo hejuru kuringaniza.
Benard vortex - Ihinduka ryumuti mugihe cyo kumisha firime yamabara bizatanga ubushyuhe, ubucucike nuburinganire bwubuso hagati yubuso n'imbere ya firime irangi. Itandukaniro rizaganisha kumuvurungano imbere ya firime irangi, bigakora icyitwa Benard vortex. Ibibazo bya firime irangi byatewe na Benard vortices ntabwo ari igishishwa cya orange gusa. Muri sisitemu irimo pigment irenze imwe, niba hari itandukaniro runaka muguhindagurika kwingirangingo za pigment, vortices ya Benard irashobora gutera kureremba no kumera, kandi hejuru yubutaka nayo izatera imirongo yubudodo.

(4) Ingaruka zikoranabuhanga ryubwubatsi nibidukikije kuringaniza.
Mugihe cyo kubaka no gukora firime yo gutwikira, niba hari imyanda ihumanya yo hanze, irashobora kandi gutera inenge zingana nko kugabanya imyobo n'amaso y'amafi. Ibyo bihumanya ubusanzwe biva mumavuta, ivumbi, ibicu, irangi ryamazi, nibindi biva mwikirere, ibikoresho byubwubatsi hamwe nubutaka. Ibiranga igifuniko ubwacyo (nk'ubwubatsi bwubwubatsi, igihe cyo kumisha, nibindi) nabyo bizagira ingaruka zikomeye kumurongo wanyuma wa firime irangi. Ubwubatsi buhanitse cyane hamwe nigihe gito cyo kumisha mubisanzwe bitanga isura idahwitse.

Nanjing Yavutse Ibikoresho bishya bitangakuringaniza abakoziharimo Organo Silicone na Non-silicon ihuye na BYK.
