Ubulunga obuqhelekileyo boMgangatho woShicilelo lweGravure kunye nezisombululo

Kwinkqubo yoshicilelo lwexesha elide, inki ngokuthe ngcembe ilahlekelwa fluidity yayo, kunye viscosity ukwanda ngokungaqhelekanga, nto leyo eyenza inki ijeli-like, Ukusetyenziswa elandelayo inki inki intsalela nzima ngakumbi.

Isizathu esingaqhelekanga:

1,Xa i-solvent kwi-inki yokushicilela i-volatilized, umbethe owenziwe ngubushushu obuphantsi bangaphandle uxutywe kwi-inki yokushicilela (ingakumbi kulula ukwenzeka kwiyunithi apho ukusetyenziswa kwe-inki yokushicilela kuncinci kakhulu).

2, Xa i-inki enobudlelwane obuphezulu namanzi isetyenziswa, i-inki entsha iya kuba ngqindilili ngokungaqhelekanga.

Izisombululo:

I-1,Izinyibilikisi zokomisa ngokukhawuleza kufuneka zisetyenziswe kangangoko kunokwenzeka, kodwa ngamanye amaxesha isixa esincinci samanzi siyakungena kwi-inki yokushicilela xa ubushushu buphezulu kwaye bufumile. Ukuba kukho into engaqhelekanga, inki entsha kufuneka izaliswe kwakhona okanye itshintshwe ngexesha. I-inki eseleyo esetyenziswa ngokuphindaphindiweyo kufuneka ihluzwe okanye ilahlwe rhoqo ngenxa yokubandakanyeka kwamanzi kunye nothuli.

2,Xoxa ukujiya okungaqhelekanga nomenzi we-inki, kwaye uphucule ukwakheka kwe-inki ukuba kuyimfuneko.

Ivumba (intsalela ye-solvent): I-solvent ye-organic kwi-inki yokushicilela iya komiswa kakhulu kwesomisi ngokukhawuleza, kodwa i-solvent trace eseleyo iya kuqiniswa kwaye idluliselwe kwifilimu yokuqala ukuze ihlale. Ubuninzi bezinto ezisele ze-solvent ze-organic-concentration kwizinto eziprintiweyo zichaza ngokuthe ngqo ukuvumba kwemveliso yokugqibela. Ukuba ayiqhelekanga na kunokujongwa ngokujoja impumlo. Ewe, ngenkqubela phambili yesayensi kunye neteknoloji, ukuvumba ngeempumlo kuye kwawa ngasemva kakhulu. Kwizinto ezineemfuno eziphezulu zeentsalela ze-solvent, izixhobo zobuchwephesha zingasetyenziselwa ukulinganisa.

Isizathu esingaqhelekanga:

1,Isantya sokuprinta sikhawuleza kakhulu

I-2, iipropathi zendalo zeerasi, izongezo kunye nezibophelelo kwii-inki zokuprinta

3, Ukusebenza kakuhle kokumisa kuphantsi kakhulu okanye indlela yokomisa ayikho

4, Umbhobho womoya uvaliwe

Izisombululo:

1. Ukunciphisa ngokufanelekileyo isantya sokushicilela

2. Imeko ye-solvent eyintsalela kwi-inki yokuprinta inokuxoxisana nomenzi we-inki ukuthatha amanyathelo okhuseleko. Ukusetyenziswa kwe-solvent eyomisa ngokukhawuleza yenza kuphela isinyibilikithi siphume ngokukhawuleza, kwaye asinayo impembelelo enkulu ekunciphiseni inani elishiyekileyo le-solvent.

3. Sebenzisa i-solvent yokumisa ngokukhawuleza okanye ukomisa ubushushu obuphantsi (ukumisa ngokukhawuleza kuya kwenza umphezulu we-inki crusted, oya kuchaphazela ukuphuphuma kwe-solvent yangaphakathi.

4. Ekubeni i-solvent ye-organic residual nayo ihambelana nohlobo lwefilimu yasekuqaleni, inani le-solvent eseleyo lihluka ngohlobo lwefilimu yokuqala. Xa kufanelekile, sinokuxoxa ngengxaki yentsalela ye-solvent kunye nefilimu yokuqala kunye nabavelisi be-inki.

5. Ucoce rhoqo umbhobho womoya ukuze uphume kakuhle
