Umkhiqizi ochwepheshe wemishini yokushisa ukushisa.
Ukubunjwa kwe-PVC: I-PVC iyi-polymer ye-thermoplastic ehlanganisa i-vinyl chloride monomers. Isakhiwo sawo samakhemikhali sinikeza ukuqina, ukuguquguquka, nokuqina.
Izakhiwo zokuvimbela i-PVC ngokumelene nomoya-mpilo, umhwamuko wamanzi, namanye amagesi zikwenza kube ukukhetha okuhle kakhulu kokulondoloza ubusha bokudla nokwelula impilo yeshalofu. Ukuguquguquka kwayo namandla kuqinisekisa ukuthi ukupakisha kungakwazi ukumelana nobunzima bezokuthutha nokuphatha ngaphandle kokubeka engcupheni umkhiqizo owuvikelayo. Ngaphezu kwalokho, ukucaca kwe-PVC kuvumela ukubonakala okuhle kakhulu komkhiqizo, isici esibalulekile sokwaneliseka kwabathengi kanye nezinjongo zokumaketha. Ukumelana namakhemikhali nakho kuyangena, ukuvimbela ukungcola nokugcina ubumsulwa bokuqukethwe kokudla.
Amashidi e-PVC asetshenziselwa ukwenza izixazululo ezihlukahlukene zokupakisha ukudla. Lokhu kuhlanganisa amapheshana amabhulabhula okudla ngakunye, iziqukathi ze-clamshell ezivame ukusetshenziselwa izithelo, imifino, nezinto zokubhaka, namathreyi enyama, izinkukhu, nezilwane zasolwandle. Ukuguquguquka kwe-PVC kuyivumela ukuthi ibunjwe ibe yiphakheji evikelekile cishe yanoma yimuphi umkhiqizo wokudla, esekela izidingo zemakethe ezihlukahlukene.
a.Umshini Wokwenza Ingcindezi Emibi
I-Negative Pressure Forming, eyaziwa nangokuthi i-vacuum forming, inqubo yokwenza i-thermoforming elula lapho ishidi le-PVC elishisayo lidonswa phezu kwesikhunta futhi lingaphansi kokucindezela kwe-vacuum. Lobu buchwepheshe bufaneleka ngokukhethekile ekudaleni imiklamo yephakheji enemininingwane ngezindleko eziphansi, okubalulekile embonini yokudla encintisana kakhulu. Ukusetshenziswa kokucindezela okungalungile kuqinisekisa ukuthi ishidi le-PVC lihambisana ngokuqondile nesikhunta, okuholela ekugqimeni okufanayo kanye nekhwalithi ehambisanayo emikhiqizweni eqediwe.
b. Umshini Wokwenza Ivacuum Yepulasitiki
Ngokufana nokusebenza Komshini Wokwenza Ingcindezi Emibi, Umshini Wokwenza I-vacuum Yepulasitiki uthatha lesi sinyathelo ngokuqhubekayo ngokunikeza ukulawula okunembe kakhudlwana phezu kwenqubo yokwenza. Lokhu kunemba kubalulekile ekwenzeni ukupakishwa kwemikhiqizo yokudla ebucayi, lapho ngisho nokuchezuka okuncane kungaholela ekonakaleni noma ekungcoleni komkhiqizo. Amandla omshini wokuphatha amanani aphezulu okukhiqiza awenza ulungele ukuhlangabezana nesidingo esikhulu esivamile embonini yokupakisha ukudla.
a. Izici Zokuvimbela: I-PVC inikeza izakhiwo ezinhle kakhulu zokuvimbela umoya-mpilo, umswakama, namanye amagesi, okusiza ekugcineni ubusha nokwelula impilo yeshalofu yemikhiqizo yokudla. Lokhu kubaluleke kakhulu ezintweni ezibolayo njengenyama, ubisi, nokudla osekulungele ukudliwa.
b. Amandla Emishini: Amandla nokuqina kwe-PVC kuyenza imelane nomthelela nokuklebhuka, inikeze ukuvikeleka okuthembekile kwemikhiqizo yokudla ngesikhathi sokuthutha nokuphatha. Lokhu kunciphisa ingozi yokuphulwa kwephakheji okungaholela ekonakaleni noma ekungcoleni kokudla.
c. Ukusebenza Kwezindleko: I-PVC ayibizi kakhulu ukuyikhiqiza uma iqhathaniswa namanye ama-polymer amaningi asetshenziswa ekufakweni kokudla. Lokhu kuphumelela kwezindleko kwenza kube inketho ekhangayo kubakhiqizi abafuna ukunciphisa izindleko ngenkathi begcina izindinganiso zokupakisha zekhwalithi ephezulu.
d. Ukuhlukahluka: Ukuvumelana nezimo kwe-PVC kuyivumela ukuthi yenziwe ngezimo nobukhulu obuhlukahlukene, ihlanganise imikhiqizo eminingi yokudla. Kusukela kumafilimu amancane kuya ezitsheni eziqinile, i-PVC ingabunjwa kalula ukuze ihlangabezane nezidingo ezithile zokupakisha.
e. Ukubonisa ngale: Ukucaca kwe-PVC kuqinisekisa ukuthi imikhiqizo ibonakala kubathengi ngaphandle kokuvula ukupakisha, ukuthuthukisa isikhalazo somkhiqizo kanye nokwenza lula isinqumo sokuthenga. Lokhu kubeka izinto ngale kubalulekile ekwethembeni komthengi nokwaneliseka.
f. Ukumelana Namakhemikhali: I-PVC imelana namafutha, amafutha, namakhemikhali amaningi, okuyenza ifaneleke ukupakishwa kwezinhlobonhlobo zemikhiqizo yokudla ngaphandle kwengozi yokusebenzisana kwamakhemikhali okungafaka engozini ukuphepha kokudla.
Nakuba i-PVC inikeza izinzuzo eziningi, umthelela wayo kwezemvelo uyindaba yenkulumo-mpikiswano eqhubekayo. Ukukhathazeka mayelana nokusimama kokusebenzisa i-PVC ekufakweni kokudla kugxile emjikelezweni wayo wokuphila—ukusuka ekukhiqizeni kuya ekulahleni. Intuthuko yesimanje kubuchwepheshe bokusebenzisa kabusha isiqalile ukunciphisa lokhu kukhathazeka ngokuthuthukisa ukugaywa kabusha kwe-PVC. Ngaphezu kwalokho, imboni ishintshela ezithasiselweni ezinobungani bemvelo ukuze kuthuthukiswe izinga lokubola kwe-PVC ngemva kokusetshenziswa.
Kundawo eguquguqukayo yokupakishwa kokudla, izinto zeshidi le-PVC zigqama njengesixazululo esiguquguqukayo nesisebenzayo, enikeza inqwaba yezinzuzo kubakhiqizi, abathengisi, nabathengi ngokufanayo. Ngokuqonda izakhiwo zabo, izinhlelo zokusebenza, nemishini yokucubungula, ababambiqhaza bangasebenzisa i-PVC ukuze bathuthukise ikhwalithi yomkhiqizo, bathuthukise ukusebenza kahle kokukhiqiza, futhi bahlangabezane nezindinganiso zokulawula. Kodwa-ke, izinselelo zokusimama ezihambisana ne-PVC zigcizelela ukubaluleka kokuqamba okusha okuqhubekayo kanye nokusebenzisana ukuze kuqinisekiswe ukulingana phakathi kokusebenza kanye nesibopho semvelo emikhubeni yokupakisha ukudla.
