Namhlanje sithetha ngombala weengxowa.Abanye abathengi banenkxalabo yokuba umbala weengxowa awuyiyo into abayilindeleyo.Ngoko kutheni kukho umehluko kumbala weengxowa?
Enye, inani le-inki kwi-inconsistent
Leyo yi-viscosity eyahlukileyo ye-inki kwitanki ye-inki yomatshini wokushicilela ngamaxesha ahlukeneyo, ubungakanani bemali ye-inki kwi-inki iyahluka.Kuyo yonke inkqubo yoshicilelo lwe-gravure, ukugcina uzinzo oluhambelanayo kunye nokuhambelana kwe-viscosity ye-inki.Qaphela ukuba i-inki ye-viscosity iyatshintsha, idla ngokuchatshazelwa lutshintsho lobushushu kwindawo yoshicilelo.
Okwesibini, ukhetho lwemibala ye-inki eyahlukileyo
Ukusombulula ingxaki inki inki gravure umahluko kwifilimu yeplastiki, kufuneka sisebenzise umgangatho uzinzile, umbala ngokutenxa okanye ukutenxa inki encinane gravure.Iindidi ezahlukeneyo zokushicilela, kukulungele ukulungisa ukusetyenziswa kwe-inki yomenzi, ibhetshi yezinto eziprintiweyo, kungcono ukusebenzisa umenzi ofanayo, ibhetshi efanayo yeenki eveliswayo.
Okwesithathu, umjikelo we-inki awugudi
Ukunika ingqalelo ukugcina ukujikeleza kwe-inki egudileyo, kungcono ukusebenzisa inkqubo yokusasazwa kwe-inki, ukuqinisekisa ukuba lula ukongeza obhityileyo kunye nokongeza inki entsha, ukugcina i-inki enomgangatho olungileyo kunye ne-fluidity.
Okwesine, isantya soshicilelo kunye nesantya sokumisa inki asihambelani phambi nasemva
Isantya soshicilelo kunye nesantya sokumisa i-inki, sichaphazela ngokuthe ngqo ireyithi ye-inki ekushicileleni, ngoko ke isantya soshicilelo kunye nokutshintsha kwesantya sokumisa inki, kuya kubangela utshintsho kumbala weinki ekushicileleni.
Isihlanu, ukusetyenziswa ngokungafanelekanga kwe-squeegee
Isikhundla se-scraper, i-engile ye-scraper, uxinzelelo lwe-scraper kunye noxinzelelo lwe-cylinder yokubonisa kumbala we-inki, ngakumbi umbala we-sub-part ye-inki unempembelelo enkulu.
Isithandathu, inkqubo edibeneyo yahlukile
Itekhnoloji yokwenziwa kwezinto ezahlukeneyo, ukwenza ibhegi ye-welding ebanzi, ukutywinwa kobushushu, ukusetyenziswa kwemibala eyahlukeneyo yefilimu ehlanganisiweyo, okanye ukushicilela ngokuthe ngqo emva kwenkqubo ye-vacuum aluminizing, umbala woshicilelo nawo unempembelelo ethile.
Ungakhathazeki, umzi-mveliso wethu unamaqhinga amangalisayo okulungisa umbala wokupakisha.
Qaphela ngononophelo isampuli yombala, nikela ingqalelo ekhethekileyo ukujonga i-substrate eprintiweyo, ukusuka kwi-substrate erhabaxa kunye neqondo eligudileyo elibonakalisayo lokhetho lwe-inki.
Umzekelo: ushicilelo lwe-inki kwipleyiti ye-aluminiyam egudileyo kwaye ibonakalisa ngokugqithisileyo okanye iinkonkxa, khetha iqondo eliphezulu lokucacelwa kwe-inki kuya kunceda kakhulu ukuqaqamba kwentsimbi ye-inki.
Xa ukhetha i-inki efunekayo kumxube wombala, kuphephe ukuxuba inki eninzi kangangoko.
Zama ukusebenzisa ii-inki ezikufutshane nombala oqhelekileyo kwaye zenziwe nge-pigment enye.Ukuba usebenzisa i-foam yombala kakhulu, ukude kakhulu kumbala oqhelekileyo okhoyo, ngakumbi ukukhanya kuya kuba.Ukudibanisa idigri ye-matte yombala iphezulu, akunakwenzeka ukumodareyitha umbala wokuqala ngokuxuba umbala.Ngoko kuthiwa xa kuxutywa umbala unokusebenzisa ezimbini ezixutywe, kungekhona ezintathu, ezincinci zingcono.
Ukuhlawula ingqalelo ekhethekileyo kumandla ombala we-inki.
Ukuba ugxininiso lwe-inki olukhethiweyo aluphezulu ngokwaneleyo, kungakhathaliseki ukuba lupela njani, kodwa alukwazi ukufikelela kugxininiso lombala oluqhelekileyo.
Xa need ukongeza inki emhlophe namnyama, kufuneka ahlawule ingqalelo ekhethekileyo kwisixa esongezelelweyo kunye nokuchaneka kobunzima.
Kuzo zonke iintlobo ze-inki, i-inki emhlophe inamandla okugquma awomeleleyo.Ukuba kuninzi kufakwe, akuyi kunciphisa umbala kuphela, kodwa kwakhona kuthintele i-substrate ekuboniseni.Nangona kunjalo, ukuprinta kwii-substrates ezingalinganiyo njengelaphu le-nylon kunye nekhadibhodi, kungcono ukuprinta umaleko omhlophe njengombala wesiseko ukwenzela ukuba kuqinisekiswe ukubonakala kwemveliso eprintiweyo.Ekubeni amandla ombala we-inki emnyama anamandla kakhulu, ukuba awuqapheli ukongeza kakhulu, kuya kufuneka udibanise enye inki yombala ukuze ulungise umbala kwaye ubangele inkunkuma, ngoko ke kufuneka kuhlawulwe ingqalelo ekhethekileyo.
Xa usenza i-inki ekhanyayo,thinakufuneka igwebe ukusuka kwinqanaba lokuhanjiswa kokukhanya kwefilimu ye-inki, ingakanani i-inki emhlophe okanye i-inki ye-toning ekufuneka yongezwe ukunyenyisa umbala.
Akuvumelekanga ngokupheleleyo ukusebenzisa i-solvent (encinci) kumbala okhanyayo.I-solvent yongezwe kakhulu, ayiyi kuchaphazela kuphela ukusebenza koshicilelo, kodwa iya konakalisa isakhiwo se-inki, okukhokelela ekuhlukaneni kwee-pigments kunye neoli ye-resin.Ukubonakala kwemvula okanye ukunciphisa kakhulu iglosi kunye nokukhanya kwe-inki.
Umzi-mveliso wethu uya kuthumela umzobo oyilelwe kumthengi ngokwemfuno yomthengi ngaphambi kokuba siqale ukuveliswa kweengxowa.Ukuba ufuna ukwazi ngakumbi okanye wenze ngokwezifiso iingxowa zokupakisha ungaqhagamshelana nathi.Siza kukubonelela ngenkonzo elungileyo kunye nexabiso elifanelekileyo.
