Ungayikhetha kanjani ipayipi lepulasitiki elisezingeni eliphezulu lokuhlobisa?

Ishubhu lepulasitiki lobuhle, lokhu kupakisha okulula futhi okungabizi kunezindlela eziningi zokusebenzisa emkhakheni wamakhemikhali wansuku zonke, futhi kuthandwa kakhulu. Kuhle kakhulu ipayipi lepulasitiki lobuhleayikwazi ukuvikela okuqukethwe kuphela, kodwa futhi ithuthukise izinga lomkhiqizo, ukuze izuze abathengi abaningi emabhizinisini amakhemikhali ansuku zonke. Ngakho-ke, emabhizinisini amakhemikhali ansuku zonke, ungakhetha kanjani amashubhu epulasitiki e-osmetic asezingeni eliphezulu avumelana nemikhiqizo yawo? Ngezansi sizokwethula ezicini eziningana ezibalulekile.

Ukuqina kwezinto: Izinkampani zamakhemikhali zansuku zonke zinezidingo ezahlukene ipayipi lepulasitiki lobuhleukuqina, ngakho-ke ungakuthola kanjani ukuqina okufiswayo? I-polyethylene evame ukusetshenziswa ku ipayipi lepulasitiki lobuhles ikakhulukazi i-polyethylene enesiminyaminya esiphansi, i-polyethylene enobukhulu obuphezulu, kanye ne-polyethylene eqondile enobukhulu obuphansi. Ukuqina kwe-polyethylene enobukhulu obuphezulu kungcono kunokwe-polyethylene enobukhulu obuphansi, ngakho-ke ukuqina okufiselekayo kungafinyelelwa ngokulungisa isilinganiso se-polyethylene enobukhulu obuphezulu/i-polyethylene enobukhulu obuphansi.

Ukumelana namakhemikhali kwezinto: i-polyethylene enesiminyaminya esiphezulu inokumelana namakhemikhali okungcono kune-polyethylene enesiminyaminya esiphansi.

Ukungaguquguquki kwesimo sezulu sezinto: Ukulawula ukusebenza kwesikhathi esifushane noma eside kwe ipayipi lepulasitiki lobuhle, udinga ukucabangela: ukubukeka, ukumelana nokucindezela/nokuwa, amandla okuvala, ukumelana nokuqhekeka kokucindezeleka kwemvelo (inani le-ESCR), iphunga kanye nokulahlekelwa izithako ezisebenzayo.

Ukukhetha i-Masterbatch: i-masterbatch idlala indima ebalulekile ku- ipayipi lepulasitiki lobuhleukulawulwa kwekhwalithi. Ngakho-ke, lapho ukhetha i-masterbatch, ibhizinisi lomsebenzisi kufanele licabangele ukuthi ingabe ine-dispersion enhle, ukuhlunga kanye nokuqina kokushisa, ukumelana nesimo sezulu kanye nokumelana nomkhiqizo. Phakathi kwazo, ukumelana nomkhiqizo we-masterbatch kubaluleke kakhulu ekusetshenzisweni kwe-masterbatch. ipayipi lepulasitiki lobuhle, uma i-masterbatch ingahambisani nomkhiqizo ofakiwe, umbala we-masterbatch uzothuthela kumkhiqizo, futhi imiphumela iba mibi kakhulu. Ngakho-ke, amabhizinisi amakhemikhali ansuku zonke kufanele ahlole ukuzinza kwemikhiqizo emisha kanye ipayipi lepulasitiki lobuhles (yenza izivivinyo ezisheshisiwe ngaphansi kwezimo ezithile).

Izinhlobo zamafutha acwebezelayo nezici zawo: amafutha acwebezelayo asetshenziswa ku- ipayipi lepulasitiki lobuhleuhlobo lwe-ultraviolet UV kanye nohlobo lokomisa okushisayo, okungahlukaniswa kube ubuso obukhanyayo kanye nobuso benkungu kusukela ekubukekeni. Uwoyela ocwebezelayo awukwazi nje ukunikeza umphumela omuhle wokubona, kodwa futhi udlala indima ekuvikeleni okuqukethwe, futhi unomthelela othile ku-oxygen, umhwamuko wamanzi, kanye nesithiyo sephunga. Ngokuvamile, uhlobo lokomisa okushisayo lwe-gloss lunamathela kahle ekuphrinteni okulandelayo kwe-bronzing kanye nesikrini, kanti i-ultraviolet UV gloss inokukhanya okungcono. Amabhizinisi amakhemikhali ansuku zonke angakhetha uwoyela ocwebezelayo ofanele ngokwezici zemikhiqizo yawo. Ngaphezu kwalokho, uwoyela ocwebezelayo ophilisiwe kufanele ube nokunamathela okuhle, ubuso obubushelelezi ngaphandle kokufaka imigodi, ukumelana nokugoqeka, ukumelana nokuguguleka, ukumelana nokugqwala, kanye nokungabi nombala ngesikhathi sokugcina.

Kukholelwa ukuthi kusukela kulezi zici ezingenhla, iningi lamabhizinisi amakhemikhali nsuku zonke kufanele likwazi ukukhetha ikhwalithi ephezulu ipayipi lepulasitiki lobuhleimikhiqizo yokupakisha.
