Yisiphi Isici Esisetshenziswayo Ezimbozweni Zezinkomishi Emishinini Emincane Yokwenza I-Thermoforming?
Yisiphi Isici Esisetshenziswayo Ezimbozweni Zezinkomishi Emishinini Emincane Yokwenza I-Thermoforming?
Izivalo zendebe ezilahlwayo, njengalezo ezisetshenziswa ezitolo zekhofi, ezindaweni zokudlela ezisheshayo, kanye nezitolo zetiye ezinamabhamuza, zikhona yonke indawo ekuphileni kwethu kwansuku zonke. Ngakho-ke lezi zivalo zenziwa kanjani? Yiziphi izinto eziyinhloko ezisetshenziswayo?
Lesi sihloko sigxile ezintweni ezintathu ezivame ukusetshenziswa zesivalo—i-PET, i-PS, ne-PVC—ukuze sikusize uqonde imininingwane.
Mayelana Nemishini Emincane Yokwenza I-Thermoforming
I Umshini Wokwenza I-Thermoforming Wezivalo Ezizenzakalelayo ze-HEY04 yathuthukiswa umnyango wethu we-R&D ukuze kuhlangatshezwane nezidingo zemakethe yokupakisha.
Umshini Omncane Wokwenza I-Thermoforming unezinto zokushisa amaphaneli, ukusetshenziswa kwamandla aphansi, indawo encane yokusebenza, kanye nokusebenza okungabizi. Ngenxa yalokho, usetshenziswa kabanzi ekukhiqizeni izivalo, izembozo, amathreyi, amapuleti, namabhokisi.
Ukubaluleka Kokukhetha Izinto Ezifanele:
Ukusebenza Kahle Kokukhiqiza: Izinga lokushisa lokwakheka kwezinto kanye nesivinini sokupholisa kuthinta ngqo ubude bomjikelezo wokukhiqiza.
Ikhwalithi Yomkhiqizo: Isibonelo, ukuthi isivalo sivalwa kahle kangakanani.
Ukulawulwa Kwezindleko: Intengo yezinto ezingavuthiwe, izinga lokukhiqiza ngesikhathi sokukhiqiza, kanye nokusetshenziswa kwamandla konke kuthinta izindleko zokugcina.
I-PET
Ukucaca Nokukhanya: I-PET inikeza izakhiwo ezinhle kakhulu zokukhanya ngokwemvelo, ikhiqiza izivalo ezicacile ezibonisa kahle ama-logo omkhiqizo nombala wesiphuzo, okuthuthukisa ukukhanga komkhiqizo.
Izakhiwo Zesithiyo: Ihlinzeka ngesithiyo esihle ngokumelene nomoya-mpilo kanye ne-carbon dioxide, isiza ukugcina ukugcwala kweziphuzo ezine-carbonated futhi ivimbele ukungena kwephunga.
Kwi-Thermoforming: I-PET inezinga lokushisa elithile lokwakheka, ngakho-ke ukulawula okunembile kokushisa kuyadingeka. Ngakolunye uhlangothi, inamandla amahle okuncibilika, okusho ukuthi iyancibilika kancane ngesikhathi senqubo yokushisa, okuholela emikhiqizweni yokugcina ezinzile futhi engaguquguquki.
Ukuphepha: I-PET ibhekwa njengento ephephile yokuxhumana nokudla futhi ihlangabezana nezindinganiso zokudla.
Ivikela Imvelo: I-PET ingenye yamapulasitiki aphinde asetshenziswe kakhulu.
Ukusetshenziswa: Kusetshenziswa ekupakisheni iziphuzo ezibandayo njengezivalo zekhofi ezibandayo, izivalo zetiye ezinamabhamuza, izivalo zendebe yejusi, kanye nezivalo zezitsha zesaladi. Qaphela: I-PET ejwayelekile ivame ukumelana nokushisa ngaphansi kuka-70°C futhi ayifaneleki ezivaloni zeziphuzo ezishisayo ngaphandle kokuthi kusetshenziswa i-PET (CPET) engamelani nokushisa okuphezulu ephathwe nge-crystallization ekhethekile, yize lokhu kokugcina kubiza kakhulu.
I-PS
I-GPPS: Ivame ukusetshenziswa ezivalweni ezibonakalayo ezinkomishini ze-yogurt kanye nezitsha zama-dessert.
I-HIPS (i-High Impact Polystyrene): Ifaka izithasiselo zerabha ku-GPPS, ithuthukisa kakhulu amandla omthelela ngezindleko zokubonakala; ngokuvamile imhlophe noma imhlophe kancane.
Kwe-Thermoforming: I-PS ithamba ngokushesha uma ishiswa futhi iqine ngokushesha lapho iphola, okusiza umshini omncane wokushisa ukushisa ukwandisa isivinini sokukhiqiza futhi unciphise ukusetshenziswa kwamandla.
Ukuphepha Kokudla: Kokubili i-GPPS kanye ne-HIPS kuhambisana nezindinganiso ze-FDA zokupakisha ukudla.
Impikiswano Yezemvelo: I-PS (ikakhulukazi i-PS enwetshiwe njengezitsha ze-foam) ibhekene nokuhlolwa kwemvelo. Iyabola kancane kakhulu, futhi ingqalasizinda yayo yokuvuselela kabusha ayizinzile kangako kune-PET, okuholela emingceleni noma ekuvinjelweni kwemikhiqizo ye-PS esetshenziswa kanye ezindaweni eziningi.
Izicelo:
I-GPPS: Ivame ukusetshenziswa ezivalweni ezibonakalayo ezidingekayo ezinkomishini ze-yogurt, ezinkomishini zama-dessert.
IZINQA: Izinto eziyinhloko zezivalo zeziphuzo ezishisayo (isb., izivalo zekhofi ezishisayo, izivalo zendebe yama-noodle ezisheshayo). Ukumelana kwayo nokushisa okuhle (kufika ku-90-100°C) kanye nezindleko eziphansi kwenza kube nzima kakhulu ukukushintsha kule ndawo.
I-PVC
Ukuguquguquka Nokuvala: Izivalo ze-PVC zithambile kakhulu futhi zingakha ukulingana okuqinile, okuqinile kumarimu endebe, okudala ukuvala okusebenzayo okuvimbela ukuvuza komoya.
Ukucaca: Kungakhiqizwa ngokucaca okuphezulu.
Ukwakha i-Thermoforming: I-PVC ingakhiwa kahle ngokushisa, kodwa ukulawula izinga lokushisa ngesikhathi sokucubungula kubalulekile. Ukushisa okweqile kungabangela ukubola, kukhiphe amagesi agqwalisayo ayingozi ku- umshini omncane wokushisa ukushisa.
Ukuphepha: Lokhu kuyiphutha elikhulu le-PVC. Nakuba i-PVC emsulwa izinzile, izithasiselo ezifana nama-plasticizer (isb. ama-phthalates) kanye nama-heat stabilizer (isb., ama-compounds aqukethe i-lead noma i-cadmium) asetshenziswa ekukhiqizweni kwayo angaba yingozi. Lezi zithasiselo zingase zishintshe zibe ukudla okunamafutha noma okushisayo. Ngisho ne-PVC yezinga lokudla iphakamisa ukukhathazeka ngokuphepha kwabathengi.
Umthelela Kwezemvelo: I-PVC ibhekwa kabanzi njengenye yepulasitiki engenabungozi kakhulu kwezemvelo. Ukukhiqizwa kwayo kanye nomjikelezo wayo wokuphila kungakhipha ukungcola okungapheli kwezinto eziphilayo njenge-dioxin. Ukushiswa kungakhiqiza amagesi ane-asidi nezinto ezinobuthi, kuyilapho ukugcwalisa imfucuza kuyingozi yokukhishwa kwe-additives. Ukuphinda kusetshenziswe kabusha kuyinselele kakhulu.
Ukusetshenziswa: Izivalo zekhofi elibandayo, itiye lebhamuza, izinkomishi zejusi, izivalo zezitsha zesaladi, njll. Kodwa-ke, ukusetshenziswa kwayo kuyehla ngenxa yezinkinga okukhulunywe ngazo.
