Ngiziphi izinto ezisetjenziselwa ukuvala iinkomitjhini emitjhini emincani yokwenza ukutjhisa?
Iimvalo zekomitjhini ezilahlwako, njengalezo ezisetjenziswa eendaweni zokuthenga ikofi, eendaweni zokudlela ezithengisa ukudla okurhabako, kanye neendawo ezithengisa itiye, zikhona yoke indawo epilweni zethu zangamalanga. Njeke lezi zivalo zenziwa njani? Ngiziphi izinto eziqakathekileko ezisetjenziswako?
I-atikili le igxile ezintweni ezintathu ezivame ukusetjenziswa—i-PET, i-PS, kanye ne-PVC—ukukusiza bona uzwisise okuthileko.
Mayelana nemitjhini emincani yokwenza ukutjhisa
I Umtjhini we-HEY04 we-Othomatic Lids Thermoforming yenziwa mnyango wethu we-R&D ukuhlangabezana neemfuno zemakethe yokupakisha.
Umtjhini omncani wokufuthumela umtjhiso unephaneli yokufuthumala, ukusetjenziswa kwamandla aphasi, indawo encani, nokusebenza okubizako. Ngalokho-ke, isetjenziswa khulu ekwenzeni iinvalo, iimvalo, amathreyi, amapuleti, namabhokisi.
Ukuqakatheka kokukhetha izinto ezifaneleko:
Ukusebenza kuhle kokukhiqiza: Izinga lokutjhisa lokwakheka kwezinto kanye nebelo lokupholisa lithinta ngqo ubude bomjikelezo wokukhiqiza.
Ikhwalithi yomkhiqizo: Ukwenza isibonelo, ukuthi isivalo sivala kuhle kangangani.
Ukulawulwa kweendleko: Intengo yezinto ezisetjenziswako, izinga lokukhiqiza ngesikhathi sokukhiqiza, nokusetjenziswa kwamandla koke kunomthelela eendlekweni zokugcina.
IFUYOSITHANDWA
Ukukhanya nokucwebezela: I-PET ngokwemvelo inikela ngezakhiwo ezihle khulu zokubona, ikhiqiza iinvalo ezikhanyako ezitjengisa kuhle amalogo webhrendi nombala wesiselo, okwenza bona umkhiqizo ukhange kuhle.
Iimpawu zokuvimbela: Inikela isithiyo esihle sokujamelana ne-oksijini nekhabhoni-dayokisayidi, isiza ukugcina i-fizz eenphuzweni ezinekhabhoni begodu ivimbele ukungena kwephunga.
Ukwenza i-Thermoforming: I-PET inezinga elithileko lokutjhisa lokwenza, njeke ukulawula okuqondileko kokufuthumala kuyatlhogeka. Ngakelinye ihlangothi, inamandla amahle wokuncibilika, okutjho bona ayiguquki kangako ngesikhathi senqubo yokufuthumala, okurholela emikhiqizweni yokugcina eqinileko begodu engatjhugulukiko.
Ukuphepha: I-PET ithathwa njengento ephephileko yokuthintana nokudla begodu ihlangabezana namazinga wokudla.
Ilungele ibhoduluko: I-PET ngelinye lamapulasitiki asetjenziswa kabutjha.
Iinsetjenziswa: Isetjenziswa emaphaketheni weenselo ezibandako ezifana neenvalo zekhofi e-ayisikhwama, iinvalo zetiye ye-bubble, iinvalo zeenkomitjhana zejuzi, kanye neenvalo zesitja sesaladi. Tjheja: I-PET ejwayelekileko ivamise ukuba nokujamelana nokutjhisa okungaphasi kwama-70°C begodu ayikafaneli ukujamelana nezivalo zesiphuzo esitjhisako ngaphandle kobana i-PET (i-CPET) ejamelana nokutjhisa okuphezulu ephathwe nge-crystallization ekhethekileko isetjenziswe, nanyana yokugcina ibiza khulu.
PS
I-GPPS: Isetjenziselwa ukuvala okukhanyako eenkomitjhini zeyogathi kanye nezitja ze-dessert.
I-HIPS (i-High Impact Polystyrene): Ifaka iinthako zerabha ku-GPPS, okwenza ngcono khulu amandla womthelela ngeendleko zokukhanya; kuvamise ukuba mhlophe nofana kube mhlophe.
Ukwenza i-Thermoforming: I-PS ithambe msinyana lokha nayifuthumeleko begodu ihlala msinyana lokha nayipholileko, okusiza umtjhini omncani wokwenza umtjhiso khuphula ibelo lokukhiqiza begodu wehlise ukusetjenziswa kwamandla.
Ukuphepha kokudla: Kokubili i-GPPS ne-HIPS zikhambisana namazinga we-FDA wokupaka ukudla.
Ikulumiswano ngezebhoduluko: I-PS (khulukhulu i-PS eyandisiweko njengeenkhonteyina ze-foam) iqalene nokuhlolisiswa kwezebhoduluko. Ibola kabuthaka, begodu umthangalasiseko wayo wokubuyisela kabutjha awukasungulwa kangako ukudlula i-PET, okurholela ekutheni kube nemikhawulo nofana ukuvinjelwa kwemikhiqizo ye-PS esetjenziswa kanye eendaweni ezinengi.
Iimbawo:
I-GPPS: Kanengi isetjenziselwa ukuvala okukhanyako okutlhogeka eenkomitjhini ze-yogurt, eenkomitjhini ze-dessert.
I-HIPS: Into eqakathekileko yokwenza izivalo zesiphuzo esitjhisako (isib., izivalo zekhofi ezitjhisako, izivalo zekopi ye-noodle). Ukujamelana kwayo kuhle nokutjhisa (kufikela ku-90-100°C) kanye neendleko eziphasi kwenza bona ingathathelwa indawo endaweni le.
I-PVC
Ukuguquguquka nokuvala: Iimvalo ze-PVC zithambile khulu begodu zingenza ukuqina okuqinileko, ukulingana kuhle emaphethelweni weenkopi, okwenza ukuvala okusebenzako okungangeni umoya nokuvala amanzi okuvimbela ukuvuza.
Ukukhanya: Kungakhiqizwa ngokukhanya okukhulu.
Ukwenza i-Thermoforming: I-PVC ingenziwa i-thermoforming kuhle, kodwana ukulawulwa kwezinga lokutjhisa ngesikhathi sokucubungula kuqakathekile. Ukutjhisa okukhulu kungabanga ukubola, kukhuphe iigesi ezibolako ezilimazako umtjhini omncani wokwenza umtjhiso.
Ukuphepha: Lokhu kungumraro omkhulu we-PVC. Nanyana i-PVC ehlanzekileko iqinile, izinto ezingezelelweko ezifana namaplastiki (isib., ama-phthalates) kanye nama-heat stabilizer (isib., amakhompawundi ane-lead nofana i-cadmium) asetjenziswa ekukhiqizeni kwayo angaba nobuthi. Iinthako lezi zingathuthela ekudleni okunamafutha nofana okutjhisako. Ngitjho ne-PVC yezinga lokudla iphakamisa ukutshwenyeka ngokuphepha kwabathengi.
Umthelela Webhoduluko: I-PVC ithathwa njengenye yamapulasitiki angalimazi ibhoduluko. Ukukhiqizwa kwayo nomjikelezo wokuphila kwayo kungakhipha izinto ezisilaphazako eziphilako ezifana nama-dioxin. Ukutjhiswa kungakhiqiza amagesi ane-esidi kanye nezinto ezinobuthi, ngesikhathi ukulahla imfucuza kubeka engozini ukugeleza okungezelelweko. Ukubuyisela izinto ezisetjenzisiweko kuyinselele khulu.
Iinsetjenziswa: Izivalo zekhofi e-ayisikhwama, itiye lamabhamuza, iinkomitjhana zejuzi, izivalo zesitsha sesaladi, njll. Nanyana kunjalo, ukusetjenziswa kwayo kuyancipha ngebanga lokutshwenyeka okukhulunywe ngakho.
