Ukuguquka kombala ngexesha lenkqubo yokomisa inki
Ngexesha lenkqubo yoshicilelo, umbala we-inki esandula ukuprintwa uba mnyama xa kuthelekiswa nombala we-inki owomileyo. Emva kwethuba lexesha, umbala we-inki uya kuba khaphukhaphu emva kokuba ushicilelo lomile; Oku akuyongxaki ukuba i-inki iyamelana nokukhanya kokukhanya okanye ukuguquka kombala, kodwa ngokuyinhloko ngenxa yokuguquka kwebala okubangelwa ukungena kunye ne-oxidation yefilimu ngexesha lenkqubo yokomisa. I-inki yokukhulula iyangena kwaye yome, kwaye umaleko we-inki wemveliso eprintwe kumatshini wokushicilela unzima kakhulu. Ngeli xesha, kuthatha ixesha lokuba ifilimu yokungena kunye ne-oxidation yomise into engenanto.
I-inki ngokwayo ayixhathisi ukukhanya kwaye iyaphela
Ukuphela kwe-inki nokuguquka kombala akuthinteleki xa evezwe ekukhanyeni, kwaye zonke ii-inki ziya kuba namaqondo awohlukeneyo okuncipha nokuguquka kombala emva kokuvezwa ekukhanyeni. I-inki enombala okhanyayo iyaphela kwaye iba nombala kanobom emva kokuba sesichengeni sokukhanya ixesha elide. Umthubi, obomvu bekristale, kunye nohlaza luphela ngokukhawuleza, ngelixa i-cyan, eluhlaza okwesibhakabhaka, kunye nobumnyama buphela kancinci. Kumsebenzi osebenzayo, xa uxuba i-inki, kungcono ukhethe inki kunye nokumelana nokukhanya okulungileyo. Xa ulungelelanisa imibala ekhanyayo, ingqwalasela kufuneka ihlawulwe ekukhanyeni ukukhanya kwe-inki emva kokuhlanjululwa. Xa uxuba i-inki, ukuhambelana kokumelana nokukhanya phakathi kwemibala emininzi ye-inki kufuneka kuqwalaselwe.
Iimpembelelo zeasidi kunye ne-alkalinity yephepha kwi-inki ephelayo kunye nokuguquka kombala
Ngokubanzi, iphepha line-alkaline ebuthathaka. Ixabiso elifanelekileyo le-pH lephepha li-7, elingathathi hlangothi. Ngenxa yesidingo sokongeza iikhemikhali ezifana ne-caustic soda (NaOH), i-sulfides, kunye negesi ye-chlorine ngexesha lenkqubo yokwenza iphepha, unyango olungafanelekanga ngexesha le-pulp kunye nokwenza iphepha kunokubangela ukuba iphepha libe ne-acidic okanye i-alkaline.
I-alkalinity yephepha ivela kwinkqubo yokwenza iphepha ngokwalo, kwaye ezinye zibangelwa ukunamathela okuqulethe izinto ze-alkaline ezisetyenziselwa ukuveliswa kwe-post. Ukuba i-alkali ye-foam kunye nezinye i-adhesives ze-alkaline zisetyenzisiweyo, izinto ze-alkaline ziya kungena kwimicu yephepha kwaye ziphendule ngekhemikhali ngamasuntswana e-inki kwiphepha lephepha, ezibangela ukuba ziphele kwaye ziguqule umbala. Xa ukhetha imathiriyeli ekrwada kunye nokuncamathelisa, kuyimfuneko ukuba kuqala uhlalutye iimpawu eziphathekayo kunye nemichiza yokuncamathelisa, iphepha, kunye nefuthe acidity kunye nealkalinity kwi-inki, iphepha, ifoyile electrochemical aluminiyam, umgubo wegolide, umgubo isilivere, kunye lamination.
Amaqondo obushushu abangela ukujika kombala kunye nokutshintsha kwebala
Ezinye iimpawu zokupakisha kunye nokuhombisa zincanyathiselwe kwiziko lokuphekela irayisi zombane, izitofu zoxinzelelo, izitovu ze-elektroniki, kunye nempahla yasekhitshini, kwaye i-inki ikhawuleza iphele kwaye iguqulwe phantsi kobushushu obuphezulu. Ukumelana nobushushu be-inki malunga ne-120 degrees Celsius. Oomatshini bokushicilela be-offset kunye nabanye oomatshini bokushicilela abasebenzi ngesantya esiphezulu ngexesha lokusebenza, kwaye iirola ze-inki kunye ne-inki, kunye ne-inki kunye nepleyiti yepleyiti yokushicilela zivelisa ubushushu ngenxa yokukhuhlana kwesantya esiphezulu. Ngeli xesha, i-inki iphinda ivelise ubushushu.
Ukutshintsha kombala okubangelwa kulandelelwano lombala olungafanelekanga ekushicileleni
Ulandelelwano lwemibala olusetyenziswa ngokuqhelekileyo kumatshini we-monochrome onemibala emine yile: Y, M, C, BK. Umatshini wemibala emine unolandelelwano lwemibala ebuyela umva: BK, C, M, Y, emisela ukuba yeyiphi i-inki emayiprintwe kuqala kwaye emva koko, enokuchaphazela ukuncipha kunye nokuguquka kombala we-inki yokushicilela.
Xa ulungiselela ulandelelwano lombala woshicilelo, imibala ekhanyayo kunye nee-inki ezithanda ukubuna kunye nokuguquka kombala kufuneka ziprintwe kuqala, kunye nemibala emnyama kufuneka ishicilelwe kamva ukunqanda ukubuna kunye nokuguquka kwebala.
Ukuguquka kombala kunye nokuguquka kwebala okubangelwa ukusetyenziswa kakubi kweoli eyomileyo
Ubungakanani beoli ebomvu yokumisa kunye neoli emhlophe eyomileyo eyongezwe kwi-inki akufanele idlule i-5% yemali ye-inki, malunga ne-3%. Ukomisa ioyile inefuthe elinamandla le-catalytic kumaleko we-inki kwaye ivelisa ubushushu. Ukuba isixa seoli yokomisa sikhulu kakhulu, kuya kubangela ukuba inki iphele kwaye iguqulwe.
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.
