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
