Indlela yokukhetha iityhubhu zeplastiki ezikumgangatho ophezulu
Iityhubhu, izinto zokupakisha ezilula nezingabizi kakhulu, zisetyenziswa kakhulu kwishishini leekhemikhali zemihla ngemihla kwaye zithandwa kakhulu. Umbhobho osemgangathweni ophezulu awunakukhusela kuphela umxholo kodwa ukwaphucula nenqanaba lemveliso, ngaloo ndlela unceda amashishini eekhemikhali zemihla ngemihla afumane abathengi abaninzi. Ke, kumashishini eekhemikhali zemihla ngemihla, ungazikhetha njani iityhubhu zeplastiki ezikumgangatho ophezulu ezifanelekileyo kwiimveliso zawo? Ngezantsi, siza kwazisa kwiinkalo ezininzi ezibalulekileyo.
Ukuqina kwezinto: Iimfuno zokuqina kweetyhubhu ziyahluka phakathi kwamashishini eekhemikhali emihla ngemihla. Ngoko ke, ukuqina okufunekayo kungafezekiswa njani? I-polyethylene esetyenziswa kakhulu kwiityhubhu ibandakanya i-polyethylene enoxinano oluphantsi, i-polyethylene enoxinano oluphezulu kunye ne-polyethylene enoxinano oluphantsi oluthe ngqo.
Ukuxhathisa kweekhemikhali kwizinto: I-polyethylene enoxinano oluphezulu inokumelana okungcono kweekhemikhali kune-polyethylene enoxinano oluphantsi.
Ukumelana nemozulu kwezinto: Ukulawula ukusebenza kwexesha elifutshane okanye elide kweetyhubhu, izinto ezifana nenkangeleko, ukumelana noxinzelelo/ukuwa, amandla okutywina, ukumelana nokuqhekeka koxinzelelo lokusingqongileyo (ixabiso le-ESCR), ivumba elimnandi kunye nokulahleka kwezithako ezisebenzayo kufuneka kuqwalaselwe.
Ukukhethwa kwee-masterbatches zemibala: Ii-masterbatches zemibala zidlala indima ebalulekileyo kulawulo lomgangatho weetyhubhu. Ke ngoko, xa ukhetha ii-masterbatches zemibala, amashishini abasebenzisi kufuneka aqwalasele ukuba zinokusasazeka kakuhle na, zihluzwe kwaye zizinzile kubushushu, zichasane nemozulu kwaye zichasane nemveliso. Amashishini eekhemikhali emihla ngemihla kufuneka avavanye uzinzo lweemveliso ezintsha kunye neetyhubhu (enze uvavanyo olukhawulezileyo phantsi kweemeko ezithile).
Iintlobo zevarnish kunye neempawu zazo: Ivarnish esetyenziselwa iityhubhu yahlulwe ngohlobo lwe-ultraviolet (UV) kunye nohlobo olomileyo ngobushushu. Ngokwembonakalo, inokwahlulwahlulwa ngakumbi ibe yi-glossy kunye ne-matte. Ivarnish ayiboneleli nje kuphela ngesiphumo esihle sokubonakala, kodwa ikwakhusela umxholo kwaye inesiphumo esithile sokuthintela ioksijini, umphunga wamanzi kunye nevumba elimnandi.
Iimfuno zomzimba wombhobho/intloko yombhobho: 1. Umphezulu womzimba wombhobho kufuneka ube bushelelezi kwaye ucoceke, ungabi namigca, imikrwelo, imikrwelo, kunye nokuguquguquka kokuncipha. Umzimba wombhobho kufuneka uthe tye kwaye ungagobi. Ubukhulu bodonga lombhobho kufuneka bufane. Ubungakanani bokunyamezelana kobukhulu bodonga lombhobho, ubude bombhobho, kunye nobubanzi kufuneka bube ngaphakathi koluhlu oluchaziweyo.
Iimfuneko zokuprinta: Ukuprinta kwe-OFFSET kudla ngokusetyenziselwa ukucutshungulwa kwepayipi, kwaye uninzi lwee-inki ezisetyenziswayo zomiswe yi-UV. Ngokuqhelekileyo kufuna ukunamathela okunamandla kunye nokumelana nombala kwee-inki. Umbala wokuprinta kufuneka ube ngaphakathi kobubanzi obuchaziweyo, indawo yokuprinta ngaphezulu kufuneka ichaneke, ukuphambuka kufanele kube ngaphakathi kwe-0.2mm, kwaye ifonti kufuneka igqibelele kwaye icace.
Iimfuno zeekhaphu zeplastiki: Iikhaphu zeplastiki zihlala zibunjwe nge-polypropylene (PP). Iikhaphu zeplastiki ezisemgangathweni ophezulu akufuneki zibe namanqaku acacileyo okushwabana okanye i-flash, umgca wokuvala isikhunta kufuneka ube bushelelezi, ubukhulu buchaneke, kwaye kufuneka zivumelane kakuhle nentloko yombhobho. Ngexesha lokusetyenziswa okuqhelekileyo, akufuneki zibangele umonakalo kwisakhiwo njengobuthathaka okanye ukuqhekeka. Umzekelo, xa amandla okuvula engaphakathi, isigqubuthelo esijikelezayo kufuneka sikwazi ukugoqwa ngaphezu kwamaxesha angama-300 ngaphandle kokuqhekeka.
Kukholelwa ukuba ngokuqala kwezi nkalo zingasentla, uninzi lwamashishini eekhemikhali zemihla ngemihla kufuneka akwazi ukukhetha iimveliso zokupakisha iityhubhu ezikumgangatho ophezulu.
