Ukushintsha umbala ngesikhathi senqubo yokumisa uyinki
Phakathi nenqubo yokunyathelisa, umbala oyinki osanda kunyatheliswa uba mnyama uma uqhathaniswa nombala oyinki omisiwe. Ngemva kwesikhathi esithile, umbala we-inki uzoba lula ngemva kokuba ukuphrinta komile; Lena akuyona inkinga ngokuthi uyinki amelana nokufiphala kokukhanya noma ukushintsha kombala, kodwa ikakhulukazi ngenxa yokushintshashintsha kombala okubangelwa ukungena kanye ne-oxidation yefilimu phakathi nenqubo yokoma. Uyinki wokusiza kakhulu ungena futhi wome, futhi ungqimba lukayinki lomkhiqizo osanda kunyatheliswa emshinini wokunyathelisa luwugqinsi uma kuqhathaniswa. Ngalesi sikhathi, kuthatha isikhathi ukuthi ifilimu yokungena ne-oxidation yome okungenalutho.
Uyinki ngokwawo akamelani nokukhanya futhi uyafiphala
Ukufiphala kukayinki nokushintsha kombala akunakugwenywa uma kuvezwe ekukhanyeni, futhi wonke ama-inki azothola amazinga ahlukahlukene okufiphala nokushintsha kombala ngemva kokuchayeka ekukhanyeni. Uyinki onombala okhanyayo uyafiphala futhi ashintshe umbala kanzima ngemva kokuchayeka ekukhanyeni isikhathi eside. Okuphuzi, okubomvu njengekristalu, nokuluhlaza kufiphala ngokushesha, kuyilapho okuluhlaza okwesibhakabhaka, okuluhlaza okwesibhakabhaka, nokumnyama kufiphala kancane kakhulu. Emsebenzini osebenzayo, lapho uxuba uyinki, kungcono ukukhetha uyinki ngokumelana nokukhanya okuhle. Lapho ulungisa imibala ekhanyayo, ukunakwa kufanele kukhokhwe ekuphikisweni kokukhanya kweyinki ngemva kokuhlanjululwa. Lapho uxuba uyinki, ukuhambisana kokumelana nokukhanya phakathi kwemibala eminingana kayinki kufanele futhi kucatshangelwe.
Umthelela we-acidity kanye ne-alkalinity yephepha ekufiphaleni kukayinki nokushintsha kombala
Ngokuvamile, iphepha line-alkaline ebuthakathaka. Inani le-pH elifanele lephepha ngu-7, elingathathi hlangothi. Ngenxa yesidingo sokwengeza amakhemikhali afana ne-caustic soda (NaOH), ama-sulfides, negesi ye-chlorine phakathi nenqubo yokwenza iphepha, ukwelashwa okungalungile ngesikhathi sokwenziwa kwe-pulp kanye nephepha kungabangela ukuba iphepha libe ne-asidi noma i-alkaline.
I-alkalinity yephepha ivela enqubweni yokwenza iphepha ngokwayo, futhi enye ibangelwa izinto zokunamathisela eziqukethe izinto ezine-alkali ezisetshenziswa ekukhiqizeni okubopha ngemuva. Uma i-alkali yegwebu nezinye izinto ezinamathelayo ezine-alkaline zisetshenziswa, izinto ezine-alkali zizongena emicu yephepha futhi zisabele ngamakhemikhali nezinhlayiya zikayinki endaweni yephepha, zibangele ukuba zifiphele futhi zishintshe umbala. Lapho ukhetha izinto zokusetshenziswa nezinamatheliso, kubalulekile ukuthi uqale uhlaziye izakhiwo ezingokomzimba nezamakhemikhali ze-adhesive, iphepha, kanye nomthelela we-acidity kanye ne-alkalinity ku-inki, ephepheni, i-electrochemical aluminium foil, impushana yegolide, impushana yesiliva, ne-lamination.
Izinga lokushisa lidale ukushintsha kombala nokushintsha kombala
Ezinye izimpawu zokuthengisa zokupakisha nezokuhlobisa zinamathiselwe ezikokeni zikagesi zerayisi, izitofu zokucindezela, izitofu zikagesi, nezitsha zasekhishini, futhi uyinki uyanyamalala ngokushesha futhi ushintshe umbala ngaphansi kwamazinga okushisa aphezulu. Ukumelana nokushisa kukayinki kuzungeze amadigri angu-120 Celsius. Imishini yokunyathelisa ye-offset neminye imishini yokunyathelisa ayisebenzi ngesivinini esikhulu phakathi nokusebenza, futhi amarola ayinki noyinki, kanye nepuleti likayinki nepuleti lokunyathelisa likhiqiza ukushisa ngenxa yokungqubuzana kwesivinini esikhulu. Ngalesi sikhathi, uyinki ukhiqiza ukushisa.
Ukushintsha kombala okubangelwa ukulandelana kombala okungafanele ekuphrinteni
Ukulandelana kombala okuvame ukusetshenziswa emshinini we-monochrome onemibala emine yilezi: Y, M, C, BK. Umshini wemibala emine unokulandelana kombala okuhlanekezela okuthi: BK, C, M, Y, okunquma ukuthi yimuphi uyinki ozophrintwa kuqala bese emva kwalokho, okungase kuthinte ukufiphala nokushintsha kombala kukayinki wokuphrinta.
Lapho uhlela ukulandelana kombala wokuphrinta, imibala ekhanyayo noyinki othambekele ekufipheleni nasekushintsheni kombala kufanele kuphrintwe kuqala, futhi imibala emnyama kufanele iphrintwe kamuva ukuze kuvinjelwe ukufiphala nokushintsha kombala.
Ukushintsha umbala nokushintsha kombala okubangelwa ukusetshenziswa okungafanele kwamafutha omile
Inani lamafutha owomisa obomvu namafutha okomisa amhlophe afakwe kuyinki akufanele lidlule u-5% wenani likayinki, cishe u-3%. Uwoyela owomisa unomphumela onamandla we-catalytic kungqimba lukayinki futhi udala ukushisa. Uma inani likawoyela omisiwe likhulu kakhulu, lizokwenza ukuthi uyinki ufiphele futhi ushintshe umbala.
Uma unezidingo zokupakisha, ungaxhumana nathi. Njengomkhiqizi wokupakisha oguquguqukayo iminyaka engaphezu kwengu-20, sizokunikeza izixazululo ezifanele zokupakisha ngokuya ngezidingo zakho zomkhiqizo kanye nesabelomali.
