Enqubweni yokuphrinta yesikhathi eside, uyinki kancane kancane ulahlekelwa ukugcwala kwawo, futhi i-viscosity ikhula ngendlela engavamile, okwenza i-jelly ye-inki ifane, Ukusetshenziswa okulandelayo kwe-inki eyinsalela kunzima kakhulu.
Isizathu esingavamile:
1,Lapho i-solvent ekuyinki yokunyathelisa iguquguquka, amazolo akhiqizwa izinga lokushisa eliphansi langaphandle axubene noyinki wokunyathelisa (ikakhulukazi ukwenzeka kalula kuyunithi lapho ukusetshenziswa koyinki wokunyathelisa kukuncane kakhulu).
2, Uma kusetshenziswa inki ehambisana kakhulu namanzi, uyinki omusha uzojiya ngendlela engavamile.
Izixazululo:
1,Izincibilikisi ezomisa ngokushesha kufanele zisetshenziswe ngangokunokwenzeka, kodwa ngezinye izikhathi amanzi amancane azongena kuyinki yokunyathelisa lapho izinga lokushisa liphezulu futhi linomswakama. Uma kwenzeka okungavamile, uyinki omusha kufanele ugcwaliswe noma ushintshwe ngesikhathi. Uyinki osele osetshenziswa kaningi kufanele uhlungwe noma ulahlwe njalo ngenxa yokubandakanyeka kwamanzi nothuli.
2,Xoxisana ngokujiya okungavamile nomkhiqizi we-inki, futhi uthuthukise ukwakheka kwe-inki uma kunesidingo.
Iphunga (izinsalela ze-solvent):I-solvent eyinki yokuphrinta izomiswa kakhulu esomisini ngokushesha, kodwa isincibilikisi esisele sizoqiniswa futhi sidluliselwe kufilimu yasekuqaleni ukuze ihlale. Inani lezinsalela ze-organic solvent ezigxilile kakhulu endabeni ephrintiwe linquma ngokuqondile iphunga lomkhiqizo wokugcina. Ukuthi akujwayelekile yini kungahlulelwa ngokuhogela ikhala. Yiqiniso, ngokuthuthuka kwesayensi nobuchwepheshe, ukuhogela ngamakhala kuye kwasalela emuva kakhulu. Kuzinto ezinezidingo eziphakeme zezinsalela zencibilikisi, amathuluzi ochwepheshe angasetshenziswa ukuzikala.
Isizathu esingavamile:
1,Isivinini sokuphrinta sishesha kakhulu
2, Izakhiwo zemvelo zama-resin, izithasiselo nama-binder kumayinki wokuphrinta
3, Ukusebenza kahle kokomisa kuphansi kakhulu noma indlela yokomisa ayikho
4,Ipayipi lomoya livaliwe
Izixazululo:
1. Yehlisa ngokufanele isivinini sokuphrinta
2. Isimo se-solvent eyinsalela ku-inki wokuphrinta singaxoxisana nomkhiqizi we-inki ukuze athathe izinyathelo zokuphepha. Ukusetshenziswa kwe-solvent esomisa ngokushesha kwenza isincibilikisi sihwamuke ngokushesha, futhi asinawo umthelela omkhulu ekunciphiseni inani elisele le-solvent.
3. Sebenzisa i-solvent eyomisa ngokushesha noma ukomisa izinga lokushisa eliphansi (ukoma ngokushesha kuzokwenza ingaphezulu likayinki liqine, okuzophazamisa ukuhwamuka kwesihlukanisi sangaphakathi. Ukomisa kancane kuphumelela ekwehliseni inani elisele le-solvent.)
4. Njengoba i-solvent esele ye-organic nayo ihlobene nohlobo lwefilimu yasekuqaleni, inani le-solvent esele liyahlukahluka ngohlobo lwefilimu yasekuqaleni. Uma kufaneleka, singaxoxa ngenkinga yezinsalela ze-solvent nabakhiqizi bokuqala befilimu noyinki.
5. Hlanza njalo umgudu womoya ukuze uphume kahle
