Uma usonga imikhiqizo emisha noma okusele nge-PVC cling film, cishe awucabangi ngamakhemikhali ayinkimbinkimbi agcina lelo phepha lepulasitiki elincane liguquguquka, licacile, futhi liphephile ukuthintana nokudla. Kodwa ngemuva kwayo yonke imigqa ye-PVC cling film esezingeni eliphezulu kuyingxenye ebalulekile:Isiqinisi se-PVCLezi zithasiselo ezingadunyiswanga zidlala indima ebalulekile ekuvimbeleni ukuwohloka, ukuqinisekisa ukuphepha, kanye nokugcina ukusebenza kahle—okwenza zibe ezibalulekile ekufakweni kokudla.
Kungani Amafilimu e-PVC Cling Edinga Izithambisi Ezikhethekile
I-PVC ayizinzile ngokwemvelo uma ivezwa ekushiseni, ekukhanyeni, nasekucindezelweni kwemishini ngesikhathi sokucubungula nokusetshenziswa kokugcina. Ngaphandle kokuzinza okufanele, i-PVC iyawohloka, ikhiphe i-hydrochloric acid eyingozi futhi ibangele ukuthi izinto zibe buthaka, zishintshe umbala, futhi zingaphephile ukuthintana nokudla.
Ngokuqondene namafilimu e-cling, izinselele zihlukile:
• Badinga ukucaca okungavamile ukuze babonise imikhiqizo yokudla
• Kumelwe ugcine ukuguquguquka emazingeni okushisa ahlukahlukene
• Isidingo sokumelana nokuwohloka ngesikhathi sokucubungula izinga lokushisa eliphezulu
• Kumelwe ulandele imithetho eqinile yokuphepha kokudla
• Kudinga ukuzinza kwesikhathi eside ngesikhathi sokugcina nokusetshenziswa
Izidingo Eziyinhloko Zama-PVC Stabilizers Asezingeni Lokudla
Akuwona wonke ama-PVC stabilizer afanele ukusetshenziswa kokuthintana nokudla. Ama-PVC cling films angcono kakhulu kumele ahlangabezane nezindinganiso eziqinile:
Ukuthobela Imithetho
Iziqinisi ze-PVC zezinga lokudla kumele zilandele imithetho eqinile emhlabeni wonke. E-United States, i-FDA's 21 CFR Part 177 ilawula izinto zepulasitiki ekuthinteni ukudla, ikhawulela izithasiselo ezifana nama-phthalates zingadluli ku-0.1% emikhiqizweni ye-PVC. Imithetho yaseYurophu (EU 10/2011) ngokufanayo ikhawulela izinto eziyingozi futhi ibeka imikhawulo yokufuduka ukuqinisekisa ukuphepha kwabathengi.
Ukwakheka Okungeyona I-Toxic
Iziqinisi zendabuko ezisekelwe ku-lead, ezazivame kakhulu ekucutshungulweni kwe-PVC, ziye zancishiswa kakhulu ekusetshenzisweni kokudla ngenxa yokukhathazeka ngobuthi.iziqinisi zokudlagwema ngokuphelele izinsimbi ezisindayo, ugxile kwezinye izindlela eziphephile.
Ukuzinza Kokushisa
Ukukhiqizwa kwefilimu ye-cling kuhilela izinqubo zokukhipha ukushisa okuphezulu kanye nokulungisa ikhalenda ezingabangela ukuwohloka kwe-PVC. Iziqinisi ezisebenzayo kumele zihlinzeke ngokuvikelwa okuqinile kokushisa ngesikhathi sokukhiqiza ngenkathi zigcina ubuqotho befilimu.
Ukugcinwa Kokucaca
Ngokungafani nemikhiqizo eminingi ye-PVC, amafilimu okunamathela adinga ukucaca okumangalisayo. Ama-stabilizer amahle kakhulu ahlakazeka ngokulinganayo ngaphandle kokudala ubumnyama noma ukuthinta izakhiwo zokukhanya.
Ukuhambisana Nezinye Izithasiselo
Ama-stabilizer kumele asebenzisane kahle nama-plasticizer, amafutha okugcoba, nezinye izithasiselo ekwakhiweni kwefilimu yokunamathela ukuze alondoloze ukusebenza kahle.
Izinketho Eziphezulu Zokuzinzisa Zamafilimu Okunamathela e-PVC
Nakuba kunezinhlobo ezahlukene zamakhemikhali okuzinza, izinhlobo ezimbili ziye zavela njengezinketho ezihamba phambili zamafilimu okunamathela asezingeni lokudla:
Iziqinisi ze-Calcium-Zinc (Ca-Zn)
Iziqinisi ze-calcium-zincsezibe yindinganiso yegolide yezinhlelo zokusebenza ze-PVC ezisezingeni lokudla. Lezi zithasiselo ezingenabo ubuthi, ezinobungani nemvelo zinikeza ibhalansi enhle yokusebenza nokuphepha:
Isiqinisi se-calcium zinc siyindlela engeyona enobuthi engenazo izinsimbi eziyingozi namanye amakhemikhali ayingozi, okwenza kube uhlobo olusha lwesiqinisi esinobungani nemvelo se-PVC.
Izinzuzo ezibalulekile zifaka:
• Ukuqina okuhle kakhulu kokushisa ngesikhathi sokucubungula
• Ukumelana nesimo sezulu okuhle kanye nokumelana nokuphuzi
• Ukuthambisa okusebenzayo okuphezulu okuthuthukisa isivinini sokukhipha
• Ukuhambisana kahle ne-PVC resin nezinye izithasiselo
• Ukuthobela imithethonqubo ebalulekile yokuxhumana nokudla
• Amandla okugcina ukucaca kumafilimu amancane
Iziqinisi ze-UV Zokuvikela Okude
Nakuba kungezona iziqinisi zokushisa eziyinhloko, iziqinisi ze-UV zidlala indima ebalulekile ekugcineni ubuqotho befilimu yokunamathela ngesikhathi sokugcina nokusetshenziswa. Lezi zithasiselo zibaluleke kakhulu kumafilimu okunamathela asetshenziswa ekupakisheni okusobala okuvezwa ekukhanyeni.
Indlela Yokukhetha Isiqinisi Esifanele Sohlelo Lwakho Lwefilimu Yokunamathela
Ukukhetha i-stabilizer efanele kudinga ukulinganisela izici eziningi:
• Ukuthobela Imithetho:Qinisekisa ukuhambisana nezindinganiso zokuphepha kokudla zesifunda (FDA, EU 10/2011, njll.) ezimakethe zakho oziqondisile.
• Izidingo Zokucubungula:Cabanga ngezimo zakho zokukhiqiza ezithile—izinqubo zokushisa eziphakeme zingadinga ukuzinza okuqinile kokushisa.
• Izidingo Zokusebenza:Hlola izidingo zokucaca, izidingo zokuguquguquka, kanye nesikhathi esilindelekile semikhiqizo yakho yefilimu yokunamathela.
• Ukuhambisana:Qinisekisa ukuthi i-stabilizer isebenza kahle nama-plasticizer akho nezinye izithako.
• Ukusimama:Funa izinto eziqinisa imvelo ezisekela imigomo yemvelo ngokunciphisa ubuthi kanye nomthelela oncishisiwe emvelweni.
• Ukuphumelela Kwezindleko:Linganisa izinzuzo zokusebenza ngokumelene nezindleko zokwakheka, ucabangela kokubili ukuhlushwa okungeziwe kanye nezinzuzo zokusebenza kahle kokucubungula.
Ikusasa Lama-PVC Stabilizers Ekupakisheni Ukudla
Njengoba isidingo sabathengi sokupakisha ukudla okuphephile nokusebenza kahle siqhubeka nokukhula, ubuchwepheshe be-PVC stabilizer buzothuthuka ukuze buhlangabezane nezinselele ezintsha. Singalindela ukubona:
• Ukuthuthukiswa okwengeziwe ekuzinzeni kokushisa ekugxilweni okuphansi kwezengezo
• Izakhiwo ezithuthukisiwe ezisekela ukuvuselelwa kabusha kanye nemigomo yomnotho ojikelezayo
• Izinhlanganisela ezintsha ze-stabilizer ezilungiselelwe izinhlelo zokusebenza ezithile ze-cling film
• Izindlela zokuhlola ezithuthukisiwe ukuqinisekisa ukuphepha nokusebenza
• Ukuqhubeka kokuvela kwemithetho okuqhuba ukusungula izinto ezintsha kwezinye izindlela ezingezona ezinobuthi
Ukusungula izinto ezintsha emkhakheni wesayensi yezinto zokwakha kuvula amathuba amasha eziqinisi ze-PVC, ucwaningo lugxile ekwakheni izixazululo ezisebenza kahle kakhulu nezisimeme zezicelo zokupakisha ukudla.
Ukutshala imali kuma-Quality Stabilizers kuma-Superior Cling Films
Isiqinisi se-PVC esifanele siyisisekelo sokukhiqiza amafilimu okunamathela asezingeni eliphezulu, aphephile, futhi ahambisanayo okupakisha ukudla. Nakuba iziqinisi ze-calcium-zinc okwamanje zihola imakethe ngokulinganisela kwazo okuhle kokuphepha nokusebenza, ukusungula izinto ezintsha okuqhubekayo kuthembisa izixazululo ezingcono nakakhulu esikhathini esizayo.
Ngokubeka phambili ukuthobela imithetho, izici zokusebenza, kanye nokucatshangelwa kwemvelo, abakhiqizi bangakhetha izinto eziqinisayo ezingagcini nje ngokuhlangabezana nezidingo zamanje kodwa futhi ezibeka imikhiqizo yabo empumelelweni yesikhathi esizayo emakethe eshintsha ngokushesha.
Njengoba imakethe ye-PVC stabilizer iqhubeka nokukhula kwayo okuqhubekayo, ukubaluleka kwalezi zithasiselo ezibalulekile ekuqinisekiseni ukuphepha nokusebenza kwamafilimu okunamathela kokudla kuzokhula kuphela—okwenza ukukhetha i-stabilizer enolwazi kubaluleke kakhulu kunanini ngaphambili.
