Kwipakethe yoshicilelo, umbala ongasemva uhlala uprintwa kuqala ukunyusa umgangatho ophezulu wokuhlobisa ipateni kwaye ulandele ixabiso eliphezulu elongezelelweyo lemveliso. Ekusebenzeni okusebenzayo, kufunyaniswe ukuba olu luhlu loshicilelo luqhelekile kwi-inki crystallization. Siyintoni isizathu soku?
I-1, Ukuze kuphunyezwe imvelaphi eqaqambileyo neqaqambileyo, umaleko we-inki uhlala uprintwa ngqindilili okanye uphinde uprintwe kanye okanye ngoxinzelelo olwandisiweyo lokushicilela, kwaye ioyile eyomileyo yongezwa ngexesha loshicilelo. Nangona umaleko we-inki ugubungela ngokupheleleyo umthuthi woshicilelo, ukomisa ngokukhawuleza kubangela umaleko wefilimu ye-inki egudileyo kumphezulu we-inki yokushicilela emva kokwenziwa kwefilimu, okwenza kube nzima ukuprinta kakuhle, njengeglasi. Oku kwenza ukuba i-inki iprintwe ingalingani okanye ingenzeki kwaphela ukuprinta. I-inki ye-oyile eprintwe kwikhava (i-stack) iveza iipateni zoshicilelo ezifana ne-bead okanye ezinombala obuthathaka kumbala wesiseko, kwaye udibaniso lwe-inki alulunganga, ezinye zazo zinokucinywa. Umzi-mveliso woshicilelo ubhekisa kuwo njengefilimu ye-inki crystallization, vitrification, okanye mirrorization.
Ukuze kuphuculwe ukucaca komfanekiso kunye nemiphetho yesicatshulwa, abaninzi abavelisi bongeze ioli ye-silicone kwiinkqubo ze-inki kwiminyaka yamuva. Nangona kunjalo, i-oyile ye-silicone egqithisileyo ihlala ibangela ukushwabana okuthe nkqo kwefilimu ye-inki.
Okwangoku kukho iimbono ezininzi ezahlukeneyo malunga nezizathu zekristali yeefilimu zeinki. Ngokutsho kwethiyori yecrystallization, icrystallization yinkqubo yokwenza iikristale kulwelo (ulwelo okanye inyibilike) okanye igesi. Into ekunyibilika kwayo kwehla ngokuphawulekayo ngobushushu obuhlayo, kwaye isisombululo sayo sinokufikelela kwisaturation kunye nokucwebezela ngokupholisa; Into ekunyibilika kwayo kwehla kancinane ngeqondo lobushushu elihlayo, ibe yikristale xa ezinye izinyibilikisi ziba ngumphunga emva koko ziphole. Abanye abantu bakholelwa ukuba i-crystallization yokupakisha imifanekiso yokushicilela kunye neetekisi (i-inki yefilimu layer) ibizwa ngokuba yi-recrystallization ... Inkqubo yefilimu ye-inki yokuprinta yenziwa ngokunyuka kwe-solvent evaporation (evaporation) kunye nokupholisa, eyaziwa ngokuba yi-recrystallization.
2, Abanye abantu bakholelwa ukuba icrystallization (crystallization) ye-inki yokupakisha ibangelwa ikakhulu yikristali ye-pigments kwinkqubo ye-inki.
Siyazi ukuba xa iikristale zepigment ziyi-anisotropic, imeko yazo yecrystalline iyinaliti okanye intonga. Xa usenza ifilimu ye-inki, ulwalathiso lobude lulungelelaniswa ngokulula kunye nolwalathiso lokuhamba kwe-resin (izinto ezidibanisayo) kwinkqubo, okubangela ukuncipha okukhulu; Nangona kunjalo, akukho lungiselelo lolwalathiso ngexesha le-crystallization spherical, ekhokelela ekunciphiseni okuncinci. Imibala ye-inorganic kwiinkqubo ze-inki yokupakisha ikholisa ukuba neekristale ezingqukuva, ezinje nge-inki yoshicilelo esekwe kwicadmium, ekwanokuncipha okuncinci (crystallization).
Ubungakanani bamasuntswana buchaphazela izinga lokuncipha kokubumba kunye nomlinganiselo wokuncipha wokubumba. Xa i-pigment particles inkulu okanye encinci ukuya kwinqanaba elithile, isantya sokubunjwa kwe-shrinkage kunye ne-shrinkage ratio yincinci. Kwelinye icala, iirasi ezineekristale ezinkulu kunye neemilo ezingqukuva zibonisa ukushwabana okuncinci kokubumba, ngelixa iiresin ezineekristale ezinkulu kunye neemilo ezingangqukuva zibonisa ukushwabana okukhulu kokubumba.
Ngamafutshane, nokuba kukuxutywa okuthotywayo kwemibala yemibala okanye ukuxuba okudityanisiweyo kokukhanya kombala, ukusetyenziswa okuchanekileyo kwee-pigments akuhambelani kuphela nokwakheka kweekhemikhali, kodwa kuxhomekeke kakhulu kwiimpawu zabo zomzimba, ezifana nokusabalalisa ubungakanani bekristal. iziganeko zokujiya, izisombululo eziqinileyo, kunye nezinye izinto ezinempembelelo; Kufuneka kwakhona senze uvandlakanyo olufanelekileyo lweengenelo kunye nokungalunganga kuzo zombini ii-pigments ze-inorganic kunye ne-organic, ukuze zihlale kunye, kwaye lo mva ubambe indawo yokuqala.
Xa ukhetha ukupakisha inki yoshicilelo (i-pigment), kukwayimfuneko ukuqwalasela amandla ayo ombala (ukusasazwa okucokisekileyo, amandla ombala aphezulu, kodwa kukho ixabiso lomda ngaphaya kwamandla ombala aya kuncipha) Amandla okugquma (iimpawu zokufunxa). yepigment ngokwayo, umahluko kwisalathiso se-refractive phakathi kwe-pigment kunye ne-resin binder efunekayo ukuze kufakwe umbala, ubukhulu bamasuntswana e-pigment, i-crystal form ye-pigment, kunye ne-molecular structure symmetry ye-pigment iphezulu kunezo ze-symmetrical. ifomu yekristale ephantsi).
Amandla okusibekela ifom ye-crystalline inkulu kunendlela yokwakheka kwentonga, kwaye amandla okugubungela i-pigments ene-crystallinity ephezulu inkulu kunee-pigments ezine-crystallinity ephantsi. Ke ngoko, okukhona amandla okugquma e-inki yokupakisha ifilimu ye-inki yokupakisha, kokukhona kunokwenzeka ukuba kubekho ukusilela kweglasi. Ukumelana nobushushu, ukuchasana nokufuduka, ukuchasana kwemozulu, ukuchasana ne-solubility, kunye nokusebenzisana kunye neepolymers (i-resins kwiinkqubo ze-ink yeoli) okanye izongezo azikwazi ukujongelwa phantsi.
3, Abanye abaqhubi bakholelwa ukuba ukhetho olungafanelekanga lunokubangela ukusilela kwecrystallization. Kungenxa yokuba i-inki esisiseko yoma kakhulu (ngokucokisekileyo), okukhokelela ekunciphiseni kwamandla asimahla. Okwangoku, ukuba ixesha lokugcinwa emva kokushicilela umbala omnye lide kakhulu, ukushisa kwe-workshop kuphezulu kakhulu, okanye kukho i-desiccants ye-inki yokushicilela, ngakumbi i-cobalt desiccants, ukuba iindlela zokomisa ngokukhawuleza kunye nokuqina, njengokumisa, zisetyenziswa, i-crystallization phenomenon. iya kwenzeka.
