Enkambisweni yokunyathelisa yesikhathi eside, uyinki ulahlekelwa kancane kancane ukugeleza kwawo, futhi i-viscosity iyanda ngendlela engavamile, okwenza uyinki ufane nejeli. Ukusetshenziswa okulandelayo koyinki osele kunzima kakhulu.
Isizathu esingavamile:
1, Lapho i-solvent ekuyinki yokunyathelisa ishintshashintsha, amazolo akhiqizwa ukushisa okuphansi kwangaphandle axutshwa kuyinki yokunyathelisa (kulula kakhulu ukwenzeka kuyunithi lapho ukusetshenziswa kweyinki yokunyathelisa kuncane kakhulu).
2, Uma kusetshenziswa uyinki onamathele kakhulu emanzini, uyinki omusha uzojiya ngendlela engavamile.
Izixazululo:
1, Izithako zokomisa ngokushesha kufanele zisetshenziswe ngangokunokwenzeka, kodwa ngezinye izikhathi inani elincane lamanzi lizongena kuyinki yokunyathelisa lapho izinga lokushisa liphezulu futhi linomswakama. Uma kwenzeka okungajwayelekile, uyinki omusha kufanele ugcwaliswe kabusha noma ushintshwe ngesikhathi. Uyinki osele osetshenziswa ngokuphindaphindiwe kufanele uhlungwe noma ulahlwe njalo ngenxa yokubandakanyeka kwamanzi nothuli.
2, Xoxani ngokujiya okungajwayelekile nomenzi we-inki, bese nithuthukisa ukwakheka kwe-inki uma kudingeka.
Iphunga (insalela ye-solvent): I-solvent ephilayo ku-inki yokunyathelisa izomiswa kakhulu emshinini wokomisa ngokushesha, kodwa i-solvent eseleyo izoqina bese idluliselwa efilimini yokuqala ukuze ihlale. Inani lezinsalela ze-solvent ephilayo ezigxilile kakhulu ezintweni eziphrintiwe linquma ngqo iphunga lomkhiqizo wokugcina. Ukuthi ayijwayelekile yini kungahlulelwa ngokuhogela ikhala. Vele, ngokuthuthuka kwesayensi nobuchwepheshe, ukuhogela ngekhala kusele emuva kakhulu. Ezintweni ezinezidingo eziphakeme zezinsalela ze-solvent, amathuluzi ochwepheshe angasetshenziswa ukuzilinganisa.
Isizathu esingavamile:
1, Isivinini sokuphrinta sishesha kakhulu
2, Izakhiwo ezingokwemvelo zama-resins, izithasiselo kanye nama-binder kuma-inki okunyathelisa
3, Ukusebenza kahle kokomisa kuphansi kakhulu noma indlela yokomisa ayitholakali
4, Umsele womoya uvaliwe
Izixazululo:
1. Nciphisa ijubane lokuphrinta ngokufanele
2. Isimo se-solvent esele ku-inki yokunyathelisa singaxoxiswana nomenzi we-inki ukuze kuthathwe izinyathelo zokuphepha. Ukusetshenziswa kwe-solvent eyomisa ngokushesha kwenza i-solvent iphele ngokushesha, futhi akunawo umthelela omkhulu ekunciphiseni inani elisele le-solvent.
3. Sebenzisa isinyibilikisi esomisa ngokushesha noma ukomisa ngezinga lokushisa eliphansi (ukomisa ngokushesha kuzokwenza ubuso beyinki bube lukhuni, okuzothinta ukuhwamuka kwesinyibilikisi sangaphakathi. Ukomisa kancane kuyasebenza ekunciphiseni inani elisele lesinyibilikisi.)
4. Njengoba i-solvent eseleyo yezinto eziphilayo ihlobene nohlobo lwefilimu yokuqala, inani le-solvent eseleyo liyahlukahluka ngohlobo lwefilimu yokuqala. Uma kufaneleka, singaxoxa ngenkinga ye-solvent residue nabakhiqizi befilimu yokuqala noyinki.
5. Hlanza njalo ipayipi lomoya ukuze likhiphe umoya kahle
