Indlela yokukhetha amashubhu epulasitiki asezingeni eliphezulu
Amapayipi, izinto zokupakisha ezilula futhi ezingabizi, asetshenziswa kabanzi embonini yamakhemikhali yansuku zonke futhi athandwa kakhulu. Ipayipi lekhwalithi ephezulu alikwazi ukuvikela okuqukethwe kuphela kodwa futhi lithuthukisa izinga lomkhiqizo, ngaleyo ndlela lisize amabhizinisi amakhemikhali ansuku zonke athole abathengi abaningi. Ngakho-ke, kumabhizinisi amakhemikhali ansuku zonke, ungazikhetha kanjani amapayipi epulasitiki asezingeni eliphezulu afanele imikhiqizo yawo? Ngezansi, sizokwethula ezicini eziningana ezibalulekile.
Ukuqina kwezinto: Izidingo zokuqina kwamapayipi ziyahlukahluka phakathi kwamabhizinisi amakhemikhali ansuku zonke. Ngakho-ke, ukuqina okufiswayo kungafinyelelwa kanjani? I-polyethylene evame ukusetshenziswa emapayipini ihlanganisa i-polyethylene ephansi, i-polyethylene ephezulu kanye ne-polyethylene eqondile ephansi.
Ukumelana nezinto ezisetshenziswa ngamakhemikhali: I-polyethylene enamandla kakhulu inokumelana okungcono kwamakhemikhali kune-polyethylene enamandla amancane.
Ukumelana nesimo sezulu kwezinto: Ukuze kulawulwe ukusebenza kwamashubhu isikhathi esifushane noma eside, izici ezinjengokubukeka, ukumelana nokucindezela/nokuwa, amandla okuvala, ukumelana nokuqhekeka kokucindezeleka kwemvelo (inani le-ESCR), iphunga kanye nokulahlekelwa izithako ezisebenzayo kudingeka kucatshangelwe.
Ukukhethwa kwama-masterbatch anombala: Ama-masterbatch anombala adlala indima ebalulekile ekulawulweni kwekhwalithi yamashubhu. Ngakho-ke, lapho ekhetha ama-masterbatch anombala, amabhizinisi abasebenzisi kufanele acabangele ukuthi anokuhlakazeka okuhle, ukuhlunga kanye nokuqina kokushisa, ukumelana nesimo sezulu kanye nokumelana nomkhiqizo. Amabhizinisi amakhemikhali ansuku zonke kufanele ahlole ukuqina kwemikhiqizo emisha namashubhu (enze izivivinyo ezisheshayo ngaphansi kwezimo ezithile).
Izinhlobo ze-varnish kanye nezici zazo: I-varnish esetshenziselwa amashubhu ihlukaniswe ngohlobo lwe-ultraviolet (UV) kanye nohlobo olumiswe ngokushisa. Ngokubukeka, ingahlukaniswa kabanzi ibe yi-glossy ne-matte. I-varnish ayigcini nje ngokunikeza umphumela omuhle wokubonakala, kodwa futhi ivikela okuqukethwe futhi inomphumela othile wokuvimba umoya-mpilo, umhwamuko wamanzi kanye nephunga.
Izidingo zomzimba wepayipi/ikhanda lepayipi: 1. Ubuso bomzimba wepayipi kufanele bube bushelelezi futhi buhlanzeke, bungabi nemivimbo, imihuzuko, imihuzuko, kanye nokuguquguquka kokushwabana. Umzimba wepayipi kufanele uqonde futhi ungagobi. Ubukhulu bodonga lwepayipi kufanele bufane. Ukubekezelelana kobukhulu bodonga lwepayipi, ubude bepayipi, kanye nobubanzi kufanele kube ngaphakathi kobubanzi obubekiwe.
Izidingo zokuphrinta: Ukuphrinta kwe-OFFSET kuvame ukusetshenziselwa ukucubungula ipayipi, futhi iningi lama-inki asetshenziswayo omisiwe nge-UV. Ngokuvamile kudinga ukunamathela okuqinile kanye nokumelana nombala kwama-inki. Umbala wokuphrinta kufanele ube ngaphakathi kobubanzi obucacisiwe bokujula, indawo yokuphrinta ngaphezulu kufanele ibe nembambo, ukuphambuka kufanele kube ngaphakathi kuka-0.2mm, futhi ifonti kufanele iphelele futhi icace.
Izidingo zama-cap epulasitiki: Ama-cap epulasitiki ngokuvamile afakwa ngomjovo owenziwe nge-polypropylene (PP). Ama-cap epulasitiki asezingeni eliphezulu akufanele abe namamaki okuncibilika noma ukukhanya okusobala, umugqa wokuvala isikhunta kufanele ube bushelelezi, ubukhulu bube bunembile, futhi kufanele avumelane kahle nekhanda lepayipi. Ngesikhathi sokusetshenziswa okuvamile, akufanele abangele umonakalo wesakhiwo njengokuqhekeka noma ukuqhekeka. Isibonelo, lapho amandla okuvula engaphakathi kwebanga, isembozo esiphendukayo kufanele sikwazi ukugoqwa izikhathi ezingaphezu kuka-300 ngaphandle kokuphuka.
Kukholelwa ukuthi ngokuqala ezicini ezingenhla, iningi lamabhizinisi amakhemikhali ansuku zonke kufanele akwazi ukukhetha imikhiqizo yokupakisha amashubhu esezingeni eliphezulu.
