Ukupholisa okubanzi akuchaphazeli nje kuphela ukuhamba komntu wonke, kodwa kunye nokuveliswa kweenkqubo zokushicilela ngenxa yemozulu ephantsi yokushisa. Ngoko ke, kule mozulu iphantsi kweqondo lokushisa, zeziphi iinkcukacha ekufuneka ziqwalaselwe kwipakethe yokuprinta? Namhlanje, i-Hongze iya kukwabelana nawe ngeenkcukacha ezifuna ukuhoywa kwinkqubo yoshicilelo kunye nokupakishwa kwimozulu ephantsi yobushushu ~

Ukuthintela Ukuqina kwe-Ink yokuShicilela yeRotary Offset
Kwi-inki, ukuba kukho utshintsho olubalulekileyo kwiqondo lokushisa kwegumbi kunye nobushushu bolwelo lwe-inki, imo yokuhamba kwe-inki iya kutshintsha, kwaye ithoni yombala iya kutshintsha ngokufanelekileyo.
Ngexesha elifanayo, imozulu ephantsi yokushisa iya kuba nefuthe elibonakalayo kwizinga lokudluliselwa kwe-inki kwiindawo zokukhanya okuphezulu. Ngoko ke, xa ushicilela iimveliso eziphezulu, kuyimfuneko ukulawula ubushushu kunye nomswakama we-workshop yokushicilela kungakhathaliseki ukuba yintoni. Ukongezelela, xa usebenzisa i-inki ebusika, kuyimfuneko ukuyitshisa kwangaphambili ukunciphisa utshintsho lobushushu be-inki ngokwayo.
Qaphela ukuba kumaqondo aphantsi, i-inki inzima kakhulu kwaye ine-viscosity ephezulu, kodwa kungcono ukuba ungasebenzisi i-diluents okanye i-oyile ye-inki ukulungisa i-viscosity yayo. Ngenxa yokuba xa abasebenzisi kufuneka bahlengahlengise iimpawu ze-inki, isixa esipheleleyo sezongezo ezahlukahlukeneyo ezinokuthi zihlaliswe kwi-inki ekrwada eveliswa ngabavelisi be-inki zilinganiselwe, zigqithise umda. Nokuba ingasetyenziswa, yenza buthathaka umsebenzi osisiseko we-inki kwaye ichaphazela umgangatho woshicilelo kunye nobugcisa bokushicilela.
Isenzeko sokutyeba kwe-inki okubangelwa bubushushu kunokusonjululwa ngezi ndlela zilandelayo:
1) Beka i-inki yokuqala kwi-radiator okanye ecaleni kwe-radiator, uyifudumeze ngokukhawuleza kwaye ngokuthe ngcembe ubuyele kwimeko yayo yangaphambili.
2) Xa ufuneka ngokukhawuleza, amanzi ashushu angasetyenziselwa ukufudumeza kwangaphandle. Indlela ethile kukugalela amanzi ashushu kwisitya, kwaye emva koko ubeke ibhakethi yokuqala (ibhokisi) ye-inki emanzini, kodwa ukuthintela umphunga wamanzi ukuba ungangeni. Xa iqondo lobushushu lamanzi lehla ukuya kutsho kuma-27 ngokukaCelsius, likhuphe, vula isiciko, kwaye ushukumise ngokulinganayo phambi kokuba uwasebenzise. Ubushushu bendibano yocweyo yoshicilelo kufuneka bugcinwe bukwiqondo elingama-27 ngokukaCelsius.

Ukusebenzisa i-antifreeze UV ivanishi
I-Varnish ye-UV nayo iyimpahla echaphazelekayo ngokulula ngamaqondo okushisa aphantsi, ngoko ke abaninzi ababoneleli bakhethekileyo ekuveliseni iifom ezimbini ezahlukeneyo: ubusika kunye nehlobo. Umxholo oqinileyo wefomula yasebusika ungaphantsi kunendlela yehlobo ehlobo, enokuphucula ukusebenza kwe-varnish xa izinga lokushisa liphantsi.
Qaphela ukuba ukuba i-formula yasebusika isetyenziswe ehlobo, kulula ukubangela ukuqiniswa kweoli okungaphelelanga, oku kunokukhokelela kwi-anti sticking kunye nezinye izinto; Ngokuchaseneyo noko, ukusebenzisa iifomyula zasehlotyeni ebusika kunokubangela ukuba i-oyile ye-UV ingasebenzi kakuhle, okukhokelela ekuphumeni kwamagwebu kunye nokusilela kwamaxolo e-orenji.

Impembelelo yoBuqondo obuPhantsi beMozulu ePhepheni
Kwimveliso yoshicilelo, iphepha yenye yezinto ezisetyenziswayo ezineemfuno eziphezulu kakhulu zobushushu bendalo nokufuma. Iphepha liyi-porous material enesakhiwo esisisiseko esakhiwe yimicu yezityalo kunye nezixhobo ezincedisayo, ezine-hydrophilicity enamandla. Ukuba ubushushu bendalo kunye nokufuma akulawulwa kakuhle, kunokubangela ukuguqulwa kwephepha kwaye kuchaphazele ukushicilelwa okuqhelekileyo. Ke ngoko, ukugcina ubushushu obufanelekileyo bokusingqongileyo kunye nokufuma ngundoqo ekuphuculeni umgangatho wamaphepha oshicilelo kunye nokuphucula ukusebenza kakuhle kwemveliso.
Iimfuno zobushushu bemo yendalo kwiphepha eliqhelekileyo azibonakali kangako, kodwa xa ubushushu bendalo bungaphantsi kwe-10 ℃, iphepha eliqhelekileyo liya kuba "brittle" kakhulu, kwaye ukuncamathelwa koqweqwe lweinki kumphezulu kuya kuncipha ngexesha lenkqubo yoshicilelo. lula ukwenza deinking.
Iphepha lekhadi legolide kunye nesilivere lidla ngokuveliswa kwiphepha eliqatywe ngobhedu, iphepha lebhodi elimhlophe, ikhadibhodi emhlophe, kunye nezinye izinto, kwaye emva koko kudityaniswe nefilimu ye-PET okanye i-aluminium foil.
Iphepha lekhadi legolide nesilivere lineemfuno eziphezulu zobushushu bendalo kuba zombini izinto zentsimbi kunye neplastiki zinovelwano kakhulu kutshintsho lobushushu. Xa iqondo lobushushu lokusingqongileyo lingaphantsi kwe-10 ℃, liya kuchaphazela kakhulu ukufaneleka kwephepha legolide kunye nekhadi lesilivere. Xa ubushushu bemeko yogcino lwephepha legolide kunye nesilivere lekhadi lijikeleze i-0 ℃, emva kokuthuthwa ukusuka kwindawo yokugcina iphepha ukuya kwindawo yokushicilela, umthamo omkhulu womphunga wamanzi uya kuvela kumphezulu wawo ngenxa yomahluko wobushushu, ochaphazela ukuprinta okuqhelekileyo kunye nokuba ekhokelela kwiimveliso zenkunkuma.
Ukuba uhlangabezana nezi ngxaki zingasentla kwaye ixesha lokuhambisa liqinile, abasebenzi banokuqala bavule ityhubhu yesibane ye-UV kwaye bavumele iphepha libaleke lingenanto kube kanye, ukuze ubushushu balo bulingane nobushushu be-ambient phambi kokushicilela ngokusesikweni.
Ukongezelela, ukomiswa kobushushu obuphantsi, ukufuma okuphantsi, nokutshintshisana kokufuma phakathi kwephepha nomoya kunokubangela ukuba iphepha lome, lijike lize lishwabene, nto leyo ebangela ukuba lingaprintwa ngokugqithisileyo.

Umphumo woBubushushu obuphantsi kwii-Adhesive Adhesives
I-Adhesive i-agent ebalulekileyo yeekhemikhali kwimveliso yamashishini namhlanje, kwaye ukusebenza kwayo kuchaphazela ngokuthe ngqo umgangatho weemveliso zoshishino.
Isalathisi esibalulekileyo sobugcisa kwimveliso yokubambelela kukulawula ukushisa. Izinto eziluhlaza zokuncamathelisa zininzi iipolymers eziphilayo, ezinokuxhomekeka okuphezulu kubushushu. Oku kuthetha ukuba iipropathi zabo zomatshini kunye ne-viscoelasticity zichaphazeleka ngokutshintsha kweqondo lokushisa. Kufuneka kucaciswe ukuba ubushushu obuphantsi bungunobangela ophambili obangela ukunamathela kwamanga kwe-adhesive.
Xa iqondo lokushisa lihla, ukuqina kwe-adhesive lukhuni, ukutshintsha umphumo woxinzelelo kwi-adhesive. Kwimeko echasene neqondo lokushisa eliphantsi, ukuhamba kwamaketanga e-polymer kwi-adhesive kunqunyelwe, ukunciphisa ukuqina kwayo.
