Izinto eziyimfuneko zemihla ngemihla aziyonto intsha kuthi. Kufuneka siqhagamshelane nazo zonke iintlobo zezinto eziyimfuneko zemihla ngemihla ukususela ekubeni sihlamba kusasa. Namhlanje siza kuthetha ngeeleyibhile zezinto eziyimfuneko zemihla ngemihla.
Kwiminyaka yakutshanje, ngophuhliso loluntu kunye noqoqosho, ushicilelo lweleyibhile luye lwatshintsha usuku ngalunye oludlulayo, kwaye luye lwangena ngokubanzi kuzo zonke iinkalo zomsebenzi kunye nobomi babantu. Phantse zonke iintlobo zeemfuno zemihla ngemihla ebomini zisebenzisa iimveliso zokuprinta iilebhile zokuzincamathelisa. Ngokwezintlu zeemveliso ezahlukeneyo, ishishini lemihla ngemihla linokwahlulwa libe ziimveliso zokhathalelo lomntu (ezifana neshampu kunye neemveliso zokhathalelo lweenwele, iimveliso zokuhlambela, iimveliso zokhathalelo lwesikhumba, izimonyo zemibala, iziqholo, njl. njl. iimveliso zokhathalelo, iimveliso zokucoca ikhitshi, iimveliso zokuhlambela, njl.njl) ukusuka kwicandelo lemarike.
Iimpawu zeemfuno zemihla ngemihla ileyibhile
1. Izinto ezahlukeneyo zoshicilelo kunye neendlela zokushicilela
Okwangoku, kukho iintlobo ezininzi zeemveliso zemichiza yemihla ngemihla kunye nokusetyenziswa okuhlukeneyo kunye nokusebenza, kubandakanywa iilebhile eziprintiweyo kwiphepha okanye iphepha elihlanganisiweyo, iilebhile eziprintwe kwi-Petrochemical polymers, kunye neelebhile eziprintwe kwiglasi kunye nesinyithi. Iileyibhile zinokuprintwa ngokwahlukeneyo kwaye zincanyathiselwe kwiimveliso, ezifana neeleyibhile zokuzincamathelisa; Inokuphinda iprintwe ngokuthe ngqo kumphezulu wemveliso, njengeleyibhile yentsimbi eprintiweyo. Ukwahluka kwemathiriyeli yoshicilelo kuya kukhokelela ngokuqinisekileyo kwiindlela ezahlukeneyo zoshicilelo.
Intsingiselo yophuhliso lwemizi-mveliso yokupakishwa kokhuselo lwendalo esingqongileyo kunye nokupakishwa okugqwesileyo kubeke phambili iimfuno eziphezulu kumgangatho woshicilelo lweelebhile zemichiza yemihla ngemihla. Ayifuni nje kuphela ukuba iileyibhile zemichiza yemihla ngemihla zibe nenkangeleko entle, ixabiso eliphantsi lokushicilela kunye nokusetyenziswa okuguquguqukayo, kodwa kukwafuna ukuba kube lula ukuphinda kusetyenziswe kwakhona kunye nokuchasana nenkohliso. Ukuze kukhawuleziswe ukuveliswa kwakhona kombala kunye neenkcukacha zeelebhile zemichiza yemihla ngemihla ukuze zichaneke ngakumbi kwaye zihle, kwaye zamkele iindlela ezahlukeneyo zokuprinta kunye neendlela zokusetyenzwa kweposi, kunye nokwamkela imathiriyeli yoshicilelo ehambelana nokusingqongileyo.
2, Ukudityaniswa kwenkcazo yemveliso kunye nokuboniswa kwemveliso
Ngophuhliso lwentlalo kunye noqoqosho lwehlabathi jikelele, iimfuno zemihla ngemihla, ngakumbi izithambiso, ziye zaba yimveliso ebalulekileyo kwiivenkile ezahlukeneyo zorhwebo kunye neevenkile. Ukhuphiswano kushishino lweemfuno zemihla ngemihla luye lwadibanisa ngokuthe ngcembe ukupakishwa kwemveliso eyahlulwe ekuqaleni kunye nomboniso wemveliso, kwaye kwakhuthaza iilebhile eziyimfuneko yemihla ngemihla ukudibanisa imisebenzi emibini ebalulekileyo yenkcazo yemveliso kunye nomboniso wemveliso ngokusebenzisa indibaniselwano yeendlela ezininzi zoshicilelo kunye nokudibanisa izixhobo zoshicilelo ezininzi, Ivumela iileyibhile zezinto eziyimfuneko zemihla ngemihla ukwenza uyilo lwemveliso, ushicilelo kunye nokulungiswa okusekwe kwimfuno yoqhelaniso "yemveliso entle, ukuchongwa okuchanekileyo, ukusebenza okuzinzileyo kunye nenkqubo eyodwa", ukuze kuqinisekiswe ukuba iileyibhile zezinto eziyimfuneko zemihla ngemihla. "zintle ngenkangeleko, zicekethekile kukwakheka, zihlala ixesha elide kwaye zithembekile".
3, Inokuqina okuhle kunye nokuzinza kweekhemikhali
Iimfuno zemihla ngemihla zineentengiso ezizodwa kunye nokusingqongileyo nokusetyenziswa, okungafuneki kuphela iileyibhile zeekhemikhali zemihla ngemihla ukuba zibe nemisebenzi ethile ukuhlangabezana nomphumo wokupakisha, kodwa kufuna kwakhona iimpawu ezizinzileyo zomzimba kunye neekhemikhali ezifana nokuxhathisa kwamanzi, ukuxhathisa ukufuma, ukuxhathisa i-extrusion, ukuxhathisa i-abrasion, ukukrazula. ukuxhathisa kunye nokumelana nomhlwa. Umzekelo, isicoci sobuso esisetyenziswa rhoqo kunye nekrimu kufuneka singanyangeki kwi-extrusion, i-abrasion kunye nokukrazula. Ukuba iimveliso zemichiza yemihla ngemihla azikhange zisetyenziswe, kwaye iileyibhile ezingaphezulu zonakaliswe okanye zivaliwe, abathengi baya kuba namathandabuzo malunga nomgangatho weemveliso. Ishampu kunye nejeli yeshawa esetyenziswa kumagumbi okuhlambela, izindlu zangasese kunye nezinye iindawo zifuna ukuba iileyibhile zabo zemichiza yemihla ngemihla zibe neempawu zokungangeni manzi, ezinobungqina bokufuma kunye neempawu zokungarhaleli. Kungenjalo, iileyibhile zinokuwa kwaye zisetyenziswe gwenxa, okukhokelela kwingozi. Ke ngoko, iimvavanyo zomzimba kunye neekhemikhali emva kokuprintwa kweelebhile zemichiza yemihla ngemihla zahluke kakhulu kwezinye iimveliso eziprintiweyo.
Izinto ezisetyenziselwa ileyibhile yeekhemikhali zemihla ngemihla
Izinto ezisisiseko zephepha lokuzincamathelisa iileyibhile ziyiphepha eligqunywe kakhulu, kwaye ukukhanya kunye nomsebenzi ongenamanzi kuphuculwe ngokugquma ifilimu. Indlela yokushicilela ngokuyinhloko i-offset yokushicilela imveliso ephezulu, kunye noshicilelo lwe-flexographic kunye noshicilelo lwesikrini kwiimveliso eziphakathi kunye nezisezantsi. Izinto ezisisiseko zeeleyibhile zokubambelela kwifilimu ziyi-PE (ifilimu ye-polyethylene), i-PP (ifilimu ye-polypropylene) kunye nemixube eyahlukeneyo ye-PP kunye ne-PE. Phakathi kwazo, izinto ze-PE zithambile, zinokulandelelwa kakuhle kunye nokumelana nokukhutshwa. Ihlala isetyenziswa kwiibhotile ezifuna ukukhutshelwa rhoqo kwaye zikhubazeke ngokulula. Izinto ze-PP zinobulukhuni obuphezulu kunye nokumelana nokuqina, okufanelekileyo ukuprinta ukusika kunye nokuleyibhile ngokuzenzekelayo. Iqhele ukusetyenziselwa "ileyibhile ecacileyo" yomzimba webhotile ocacileyo. Ifilimu ye-polyolefin exutywe kunye ne-PP kunye ne-PE ayikho nje into ethambileyo kunye ne-extrusion resistant, kodwa iphinde ibe nokuxhathisa okuphezulu. Inepropathi efanelekileyo yokulandela, ukuprinta ukusika kunye nokuleyibhela okuzenzekelayo. Yimathiriyeli yeleyibhile efanelekileyo yefilimu.
