Ungakhetha kanjani ishubhu yepulasitiki yezimonyo ephezulu?

Cosmetic plastic tube, le nto yokupakisha elula neyongayo inezinhlobonhlobo zezicelo emkhakheni wamakhemikhali wansuku zonke, futhi ithandwa kakhulu.Inhle kakhulu.ishubhu yepulasitiki yezimonyoayikwazi nje ukuvikela okuqukethwe, kodwa futhi ithuthukise izinga lomkhiqizo, ukuze uzuze abathengi abaningi bamabhizinisi amakhemikhali nsuku zonke. izokwethula ngezici ezimbalwa ezibalulekile.

Ukuqina kwempahla: Izinkampani zamakhemikhali zansuku zonke zinezidingo ezihlukile ze ishubhu yepulasitiki yezimonyoukuqina, ngakho-ke ungakuthola kanjani ukuqina okufunayo? I-polyethylene evame ukusetshenziswa kakhuluishubhu yepulasitiki yezimonyosikakhulukazi i-polyethylene enezinga eliphansi, i-polyethylene enokuminyana okuphezulu, kanye ne-polyethylene enomugqa ophansi. Ukuqina kwe-polyethylene ephakeme kakhulu kungcono kune-polyethylene ephansi, ngakho ukuqina okufunayo kungafinyelelwa ngokulungisa isilinganiso se-polyethylene ephezulu / i-low density polyethylene.

Ukumelana namakhemikhali wento: i-polyethylene ephezulu kakhulu inokumelana namakhemikhali okungcono kune-polyethylene ephansi.

Isimo sezulu sezinto ezibonakalayo: Ukulawula ukusebenza okufushane - noma kwesikhathi eside kwe-ishubhu yepulasitiki yezimonyo, udinga ukucabangela: ukubukeka, ukumelana nokucindezela / ukwehla, amandla okufaka uphawu, ukumelana nokucindezeleka kwemvelo (inani le-ESCR), iphunga nokulahlekelwa kwesithako esisebenzayo.

Ukukhetha kwe-Masterbatch: i-masterbatch idlala indima ebalulekileishubhu yepulasitiki yezimonyoikhwalithi yokulawula. Ngakho-ke, lapho ukhetha i-masterbatch, inkampani yomsebenzisi kufanele icabangele ukuthi inokuhlakazeka okuhle, ukuhlunga nokuzinza kokushisa, ukumelana nesimo sezulu kanye nokumelana nomkhiqizo. Phakathi kwabo, ukumelana komkhiqizo we-masterbatch kubaluleke kakhulu ekusetshenzisweni kwe-ishubhu yepulasitiki yezimonyo, uma i-masterbatch ingahambisani nomkhiqizo ofakiwe, umbala we-masterbatch uzothuthela kumkhiqizo, futhi imiphumela mibi kakhulu. Ngakho-ke, amabhizinisi amakhemikhali nsuku zonke kufanele ahlole ukuzinza kwemikhiqizo emisha kanyeishubhu yepulasitiki yezimonyos(yenza izivivinyo ezisheshisiwe ngaphansi kwemibandela ethile).

Izinhlobo zikawoyela ocwebezelayo nezici zazo ezihlukene: uwoyela ocwebezelayo osetshenziswa ku-ishubhu yepulasitiki yezimonyouhlobo lwe-ultraviolet UV kanye nohlobo lokumisa olushisayo, olungahlukaniswa endaweni ekhanyayo nenkungu ebusweni kusukela ekubukeni. Amafutha e-Gloss awakwazi nje ukunikeza umphumela omuhle wokubuka, kodwa futhi abambe iqhaza ekuvikeleni okuqukethwe, futhi abe nomthelela othile ku-oxygen, umhwamuko wamanzi, umgoqo wephunga. Ngokuvamile, uhlobo olushisayo lokumisa olucwebezelayo lunokunamathela okuhle kokulandelayo kwe-bronzing nokuphrinta isikrini, futhi isicwebezelisi se-ultraviolet UV sinokucwebezela okungcono. Amabhizinisi wansuku zonke wamakhemikhali angakhetha uwoyela ocwebezelayo ofanele ngokwezimpawu zemikhiqizo yawo. Ngaphezu kwalokho, uwoyela we-gloss ophulukisiwe kufanele ube nokunamathela okuhle, indawo ebushelelezi ngaphandle kokugoba, ukumelana nokugoqa, ukumelana nokugqoka, ukumelana nokugqwala, futhi kungabi nombala ngesikhathi sokugcinwa.

Kukholakala ukuthi kulezi zici ezingenhla, iningi lamabhizinisi amakhemikhali nsuku zonke kufanele akwazi ukukhetha izinga eliphezulu.ishubhu yepulasitiki yezimonyoimikhiqizo yokupakisha.
