Iimpawu kunye nezakhono zokuprinta ze-inki esekwe emanzini yephepha eliqinisekisiweyoibhokisi yetshokholethi
I-inki esekwe emanzini yimveliso ye-inki enobuhlobo obufumene ingqalelo ebanzi kwiminyaka yakutshanjeibhokisi ye-pastry. Nguwuphi umahluko phakathi kwe-inki esekwe emanzini kunye ne-inki ePrinta ngokubanzi, kwaye ngawaphi amanqaku afuna ingqalelo? Apha, iMeibang iya kuyicacisa ngenkcukacha kuwe.
I-inki esekwe emanzini isetyenzisiwe ekuprintshwe iphepha elifudumeleyo ixesha elide nangaphezulu kweminyaka engama-20 ekhaya. Ukuprinta iphepha eliDityanisiweyo kuphuhliswe kwiPrinta ekhokelayo (ukuPrinta ngoncedo), ukushicilelwa kwe-Offset (ukuPrinta i-Offset) kunye neRuber Pleber Pleit eSebenzayo. I-IK i-inki yoncedo esekwe kumanzi aguqukayo iphinde yaphuhliswa kwi-Rosin-Maleatic Acid Serin (Ibanga eliphantsi) ukuya kwi-Acrylin Retin Serin (ibanga eliphezulu). Iplate yokushicilela ikwahamba kwiplate yerabha ukuya kwiplate. Umatshini wokushicilela uthule ngokuthe ngcembe ukusuka kumbala omnye okanye oomatshini beembala ezimbini kunye nombala omninzi omkhulu okanye oomatshini abanemibala emine.
Ukuqulunqwa kunye neempawu zee-inki ezisekwe emanzini ziyafana nezo zee-interks jikelele. Ii-Inki ezisekwe emanzini zidla ngokudityaniswa kwezikolo, iibhasi, ii-auxiline kunye nezinye izinto. I-Colorants zizikolo ze-inki ezisekwe emanzini, enika i-inki umbala othile. Ukwenzela ukuba enze umbono oqaqambileyo kwiPleoragraphic Printa, abakhweli ngokubanzi basebenzisa ngokubanzi imibhobho yokuzinza kweekhemikhali ezifanelekileyo kunye namandla amakhulu; I-Binder inamanzi, i-resin, imingxunya ye-amine kunye nezinye izinyibilikisi eziphilayo. I-resin yeyona nto ibaluleke kakhulu kwii-Inki ezisekwe emanzini. I-rerble i-acrycl ye-acryclin ihlala isetyenziswa. Icandelo le-Binder lichaphazela ngokuthe ngqo ukusebenza kwe-adhesion, isantya esomisa, ukusebenza okuchasene noko, njl njl. I-Amine imiqathango igcina ubukhulu becala i-Alkaline PH ye-inki esekwe emanzini, ukuze i-acryc resin inokubonelela ngempembelelo engcono yokuprinta. Amanzi okanye ezinye izinyibilikisi ze-organic zichithwe ichithwa, zilungelelanise i-viscofity kunye nesantya esomileyo se-inki; Abancedisi abancediswayo babandakanya ikakhulu: UDefoamer, iBlocker, Stabilizer, HiLuent, njl.
Njengoko i-inki esekwe emanzini kukwenziwa kwesepha, kulula ukuvelisa iibhubhu ezisetyenziswayo, ukuze ioyile yesilika kufuneka yongezwe njenge-Defoamer ukuthintela kwaye isuse ukusebenza kwe-inki. Iiblockers zisetyenziselwa ukuthintela isantya esomileyo se-inki esekwe emanzini, thintela i-inki ekubeni iphume kwi-Anilox Roll kwaye inciphise i-paste. Isimilo sinokulungelelanisa ixabiso le-inki, kwaye linokusetyenziswa njengendawo engaqhelekanga ukunciphisa i-inki. I-diuent isetyenziselwa ukunciphisa umbala kwi-inki esekwe emanzini, kwaye inokusetyenziswa njengesixhobo esikhanyayo sokuphucula ukukhanya kwe-inki esekwe emanzini. Ukongeza, ezinye i-wax kufuneka zongezwe kwi-inki esekwe emanzini yokwandisa ukuxhathiswa kwalo.
I-inki esekwe emanzini inokudityaniswa namanzi ngaphambi komonga. Nje ukuba i-inki yomile, ayisayi kuphinda inyibilike emanzini nasekk. Ke ngoko, i-inki esekwe emanzini kufuneka ivuselelwe ngokupheleleyo ngaphambi kokuba isetyenziselwe ukugcina iyunifomu ye-Inki. Xa usongeza i-inki, ukuba i-inki eshiyekileyo kwitanki i-inki iqulethe ukungcola, kufuneka icofe kuqala, kwaye isetyenziswe nge-inki entsha. Xa uprinta, ungavumeli i-inki eyomileyo kwi-Anilox Roll yokuthintela ukuvimba umngxunya we-inking. Ukuthintela ukuhanjiswa kwe-inki kubangela ukungazinzi. Ngexesha lenkqubo yokuprinta, i-flexplate kufuneka ihlale imanzi yi-inki yokuphepha ukuvimba iphethini kwiplate yokuprinta emva kokuba i-inki yomile. Ukongeza, kufuma kwafunyanwa ukuba xa i-inki esekwe emanzini iphakame kancinci, ayifanelekanga ukongeza amanzi Unokongeza isixa esifanelekileyo se-stabilizer ukuyitshintsha.
Ixesha lokuphumla: Mar-15 ukuya kwi-2023
