Ukutsala i-inki kubhekiselele kwinkqubo yokulambisa, apho iglu itsalela phantsi umaleko we-inki kumphezulu wokushicilela we-substrate yokushicilela, ibangela ukuba i-inki ibambelele kwi-roller yerabha ephezulu okanye i-mesh roller. Isiphumo singumbhalo ongaphelelanga okanye umbala, obangela ukuba imveliso ichithwe. Ngaphezu koko, i-inki eqhotyoshelwe kwi-roller yeglue ephezulu idluliselwa kwipatheni elandelayo, ibangela inkunkuma. Inxalenye engenambala inamabala e-inki kunye nokuncipha okukhulu kokungafihli, okuchaphazela umgangatho wemveliso.
1.Inxulumene nobungakanani beglue esetyenzisiweyo kunye nokugxilwa kokusebenza
Amathuba ento enye encamathelayo encamathelayo encamathelayo enyibilikayo eshushu iphezulu kunento encamathelayo emibini,engenakuhlulwa kolona hlobo lokuncamathelayo oluphambili kunye ne-diluent.
Ngenxa yobuncinci beglu esetyenzisiweyo, isixa se-inki esitsalwa phantsi sikwimo yeentambo ezicolekileyo, njengeempawu ezibangelwa ziimeteors. La machaphaza amahle abonakala kakhulu kwindawo engenanto yefilimu yeplastiki, kwaye kwinxalenye ephethe ipateni, ukuqwalaselwa ngokucophelela kuyimfuneko ukuyifumana. Ubungakanani begluing yohlobo lwe-scraper umatshini owomileyo wokulambisa uchongwa ngenani lemigca kunye nobunzulu be-anilox roller. Uxinzelelo olugqithisileyo kwi-scraper ngexesha lokusebenza kwangempela kuya kunciphisa inani leglue elisetyenzisiweyo. Ukuba inani leglue elisetyenzisiweyo lincinci, i-phenomenon ye-inki yokudonsa inzima, ngelixa ukuba inani leglue elisetyenzisiweyo likhulu, i-phenomenon ye-inki yokudonsa iyancitshiswa.
Ukugxininiswa komsebenzi wesikolo wasekhaya kuhambelana ngokusondeleyo nesiganeko sokutsalwa kwe-inki.Ukuba ukuxinwa kwe-adhesive yecandelo elinye kungaphantsi kwe-35%, umxholo oqinileyo we-adhesive oyintloko ungaphantsi kwe-3g /㎡, okanye ukuxinwa kwe-adhesive esebenzayo yamacandelo amabini kungaphantsi kwe-20%, kwaye umxholo oqinileyo we-adhesive main ungaphantsi kwe-3.2g /㎡, kulula ukwenzeka isenzeko somzobo we-inki, ekwanxulumene neyona nkqubo yokusebenza. Ukuba i-concentration yokusebenza iphantsi kwaye i-inki yokudonsa iyenzeka, kuyimfuneko ukunyusa i-concentration yokusebenza ukuyicombulula, oko kuthetha ukwandisa inani le-arhente eyintloko okanye ukunciphisa inani le-diluent esetyenzisiweyo.Ngokuqhelekileyo, ukuxinwa okusebenzayo kwecandelo elilodwa kulawulwa malunga ne-40%, kwaye kungcono ukulawula ukuxinwa kwamacandelo amabini malunga ne-25-30%, ukwenzela ukuba i-ink dragging phenomenon inokusombulula.
2. Enxulumene noxinzelelo lwe-glue roller
Kwinkqubo edibeneyo eyomileyo, i-gluing pressure roller idla ngokusetyenziswa, esetyenziswayoyenza i-gluing i-gluing ibe yinto efanayo kwaye unciphise ukuveliswa kweebhubhu. Xa ukutsalwa kwe-inki kwenzeka, ngaphezu kokuqwalasela inani leglue elisetyenzisiweyo kunye nokugxininiswa kokusebenza, kuxinzelelo lwe-rubber roller.
Ngokuqhelekileyo, xa uxinzelelo ludlula i-4MPa, kukho ithuba lokutsalwa kwe-inki. Isisombululo kukunciphisa uxinzelelo, kwaye kwangaxeshanye, umqhubi onobuchule kufuneka asebenzise ilaphu ukuncamathela i-diluent ukucima indawo ye-inki ye-anilox roller eqhubayo. Ukuba inzima kakhulu, i-anilox roller kufuneka imiswe ukucoca.
3. Enxulumene nomgangatho we-glue roller
I-roller yerabha iayigudi okanye intekenteke, kwaye inokurhuqa i-inki, ebonakala ngokulula kwicandelo elinye lezinto zokuncamathelisa ezinyibilikayo ezishushu.
Ngenxa yokungalingani kunye noburhabaxa be-resin, i-inki ekhutshiweyo ayifani kwaye isasazwa ngokulinganayo, ishiya amabala e-inki kwindawo engenanto, ekhokelela ekunciphiseni kokungafihli, ukulahleka kwe-inki ngombala, kunye nokubhaliweyo okungaphelelanga. Ukutshintsha le nto, kuyimfuneko ukutshintsha i-roller ye-gluing egudileyo kunye nethambileyo.
4. Enxulumene nesantya somatshini kunye nobushushu bokumisa
Isantya somatshini sibonisa ukuba i-interface phakathi kwe-inki layer kunye ne-adhesive kwi-film layer ithatha utshintsho kwixesha lokumanzisa.
Ngokuqhelekileyo, ngenxa yesantya esicothayo somatshini, kukho isenzeko sokutsalwa kwe-inki, esombululeka ngokunyusa isantya kunye nokunciphisa ixesha lokuhlala phakathi koluhlu lwe-inki kunye ne-adhesive interface. Kwithiyori, ukuba isantya somatshini sinyukile, ubushushu bokumisa kufuneka bonyuswe. Ngexesha elifanayo, ukuba isantya somatshini sandiswa ngexesha lokusebenza kwangempela, kufuneka kubonwe ukuba kukho ezinye iimpazamo, ezifana nokufuduka kwezinto eziphathekayo, kunye nokulungelelaniswa okuhambelanayo kufuneka kwenziwe.
5. Enxulumene nokubambelela kwi-substrate yokushicilela okanye i-inki
Ukuba iintlobo ezahlukeneyo ze-inki zisetyenziselwa ukuprinta i-gravure, ukwenzeka kweziphene kubonakala ngokulula ngexesha le-lamination.
I-inki inokohlulwa ibe yi-inki yoshicilelo engaphezulu kunye ne-inki yoshicilelo lwangaphakathi. Ngenxa yeentlobo ezahlukeneyo zeinki, ukunamathela kwabo kunokungafani okanye kungahambelani, kwaye ukunamathela obuthathaka kunokukhokelela ekubambeni obuthathaka. Xa i-lamination eyomileyo isetyenziselwa, kulula ukubangela ukutsalwa kwe-inki. Xa ukuxinana komphezulu we-substrate yoshicilelo kubi, kuyathandeka ngakumbi ukutsalwa kwe-inki.
Uluhlu lwe-inki olutsalweyo lubonakala lulonke, kwaye i-inki ibambelela kwisitya seglue, ibangela i-turbidity kunye nokungcola. Ukuba sele ishicilelwe, ukwenzela ukuba ugweme inkunkuma, isantya somatshini sinokunyuswa, isixa seglue sinokunyuswa, kwaye i-glue concentration inokunyuswa ngexesha elifanayo. Nciphisa uxinzelelo kwi-roller yerabha ngelixa unciphisa ukunyanzeliswa kwe-unwinding.
6. Enxulumene nezinto zoomatshini
Ngethuba lokusebenza, ukuba ukusilela komatshini kwenzeka, kubangelei-gluing engalinganiyo okanye i-coating engafanelekanga, kunokubangela ukutsalwa kwe-inki.
Ukulungelelaniswa kwe-rubber roller ephezulu kunye ne-anilox roller igqitywe ngamagiya amabini ahambelanayo. Ukuba kukho isenzeko sokutsalwa kwe-inki, kufuneka kuqwalaselwe ngononophelo. Kuya kufunyanwa ukuba i-inki yokudonsa iyenzeka ngenxa yokugubha i-roller ye-rubber ephezulu kunye ne-coating embi. Isizathu sokungcangcazela singenxa yokunxiba kakhulu kunye namazinyo e-asynchronous gear.
Ukuba unayo naziphi na iimfuno zokuPakisha, ungaqhagamshelana nathi. Njengomenzi wokupakisha oguquguqukayo ngaphezulu kweminyaka engama-20, siya kubonelela ngezisombululo zakho ezifanelekileyo zokupakisha ngokweemfuno zakho zemveliso kunye nohlahlo lwabiwo-mali.
