I-Thermoforming iyindlela yokucubungula ipulasitiki eye yathuthukiswa eminyakeni yamuva nje.
Ngokuthuthuka kwezindinganiso zokuphila zabantu kanye nezinguquko endleleni yokuphila, imikhiqizo eminingi eguquguqukayo iyavela kuzo zonke izici zokuphila kwabantu. Polypropylene (PP) amashidi Zinezici zokuqina okuphansi, ukungabi nobuthi, ukucubungula okulula, ukumelana nokugoba, kanye nokumelana okungcono kokushisa. Zifaneleka kakhulu ezindleleni zokucubungula ezifana ne-thermoforming futhi zisetshenziswa kabanzi ekupakisheni ukudla, ezimotweni, ezintweni zasekhaya nakwezinye izindawo. Ngesikhathi esifanayo, i-polypropylene ingalungiswa kabanzi ngokuya ngokuqina, ukucaca, ukuqina kokushisa okuphansi kanye nezinye izici ngokuya ngezidingo zokusebenza ezahlukene zamakhasimende.
Izimiso eziyisisekelo kanye nezici ze-thermoforming
I-Thermoforming iyindlela ekhethekile yokucubungula ipulasitiki esetshenziselwa ukuguqula amashidi e-thermoplastic abe imikhiqizo eyahlukahlukene. Ngemva kokuba ishidi le-thermoplastic selishisiwe ukuze lithambe, ingcindezi (i-vacuum noma ingcindezi enhle) isetshenziswa ukuphoqa ishidi le-thermoplastic ebusweni besikhunta ukuze kutholakale isimo esifana ne-contour. Ngemva kokupholisa nokuqina, isimo esifunekayo sitholakala ngokusika. I-Thermoforming iyashesha futhi iyafana, umjikelezo wokubumba umfushane, izindleko zesikhunta ziphansi, futhi ifaneleka ukuzenzekela kanye nokukhiqizwa kwesikhathi eside. Ibhekwa njengendlela yokucubungula ebiza kakhulu futhi esebenza kahle kakhulu phakathi kwezindlela zokubumba zepulasitiki. I-Thermoforming ithuthuke ngokushesha selokhu yavela, ikakhulukazi ngokuthuthukiswa okuqhubekayo kobuchwepheshe be-thermoforming kanye nemishini kanye nokungenelela kwezindlela zokulingisa ikhompyutha, i-thermoforming ibe yindlela eyinhloko yokucubungula encintisana nokubumba nge-injection kanye nokubumba nge-blow. Eminyakeni yamuva nje, imishini yokucubungula i-thermoforming yenze intuthuko entsha.
Izinhlobo eziyinhloko ze-thermoforming yilezi: ukwakheka kwe-vacuum, ukwakheka kwengcindezi, ukwakheka okusiza nge-plunger kanye nokuhlanganiswa kwayo. Kunemikhiqizo eminingi ye-thermoformed emakethe, njengezinkomishi, amasoso, amathileyi okudla, amathoyizi, izigqoko zokuzivikela, kanye nezingxenye zezimoto, ukuhlobisa izakhiwo, imishini yamakhemikhali, njll. Uma kuqhathaniswa nokubumba nge-injection, i-thermoforming inezinzuzo zokusebenza kahle kokukhiqiza, ukutshalwa kwezimali okuphansi kwemishini, kanye nekhono lokukhiqiza imikhiqizo emikhulu yendawo engaphezulu. Ucwaningo kanye nokuthuthukiswa kwezinto ze-polypropylene ezisebenza kahle njengokukhanya okuphezulu, amandla aphezulu okuncibilika, kanye ne-warpage ephansi kukhuthaze ukusetshenziswa kanye nokuthuthukiswa kwamashidi e-polypropylene emkhakheni we-thermoforming.
Amasimu okusetshenziswa kwamashidi e-PP afakwe i-thermoformed
Ukupakishwa kokudla
Imikhiqizo ye-PP eyenziwe nge-thermoformed yokupakisha ukudla ifaka amathileyi ahlukahlukene njengebhokisi elivalwe ngemifino eliphekiwe, amathileyi enyama, amathileyi e-tofu, amabhokisi esidlo sasemini alahlwayo, njll. Amanye ala mathileyi amhlophe njengobisi, amnyama, abomvu, njll., kanti amanye ayimikhiqizo esobala. Ngesikhathi esifanayo, izivalo zendebe kanye nezivalo zethileyi ezihambisana nemikhiqizo eyenziwe nge-thermoformed engenhla nazo zikhiqizwa kusetshenziswa inani elikhulu le-PP esobala.
Ukupakishwa okungekona ukudla
isetshenziswa kakhulu kuma-blister e-capsule ezokwelapha, ukupakisha amathuluzi (izinto zokubhala, izimpahla zehadiwe), imikhiqizo kagesi, kanye nezinto zokuhlanza.
Amashidi namabhokisi agoqekayo
Amashidi e-PP asetshenziswa kabanzi ezintweni zokubhala, izimonyo kanye namabhokisi okugoqa amathoyizi, ekupakisheni amafasitela kanye nasezingcezwini zokulenga ezitolo ezinkulu. Inani elincane le-PP elibonakalayo lisetshenziswa emabhokisini okugoqa aphezulu.
Ishidi le-PP Lokupakisha Ukudla Okufakwe I-Thermoformed
● Indebe
Izinkomishi ezakhiwe nge-thermoform ziyizinkomishi ezilahlwayo, njengezinkomishi zetiye lobisi, izinkomishi zeziphuzo ezibandayo, izinkomishi zokudla okusheshayo, njll. Zisetshenziswa kakhulu ezindaweni zokudlela zokudla okusheshayo, ezitolo zetiye lobisi, ezimbonini zemikhiqizo yejeli, njll. Izinto zokusetshenziswa ziyizingcezu ze-PP ezisobala kakhulu, kanti ezinye iziphuzo ezibandayo zenziwe nge-PET.
● Ibhokisi lesidlo sasemini elingamelani
Amabhokisi okudla kwasemini avamile aqukethe ukudla okushisa okuphansi kuphela. Kodwa-ke, abathengi badinga futhi ukugcina iphalishi elishisayo kanye nesobho elishisayo, noma ukulihlanza ngaphansi komusi okushisa okuphezulu. Lokhu kubeka phambili izidingo eziphakeme zezinto zokusetshenziswa ze-resin. I-PET ne-PS azimelani nokushisa okuphezulu. I-Polypropylene inokumelana okuhle nokushisa, intengo ephansi futhi kulula ukuyithola, futhi isibe yizinto zokusetshenziswa ezikhethwayo.
● Isembozo
Imikhiqizo eyinhloko ifaka phakathi izivalo zesitsha, izivalo zamabhokisi esidlo sasemini, izivalo zendebe, njll., ezisetshenziswa kakhulu ezindaweni zokudlela zokudla okusheshayo, ezitolo zetiye lobisi, ezitolo zamakhekhe, njll. Izivalo zibonakala kakhulu, kanti izivalo ze-PP zivame ukusetshenziselwa iziphuzo ezishisayo.
● Ukufakwa kokudla ngaphakathi
Ukufakwa kokudla kusetshenziselwa kakhulu ukupakisha amabhisikidi, ama-potato chips, amantongomane kanye nezinye izinto zokudla okulula. Kuzoba nongqimba lokufakwa ngaphandle, olusetshenziswa kakhulu ezimbonini zokudla okusheshayo. Njengamanje, ukufakwa kokudla kubonakala kakhulu, kodwa futhi kumhlophe njengobisi. Ukuze kwenziwe ukudla okupakishwe kugcwale futhi kungenzeki ukuthi kugaywe, izinkampani eziningi zokucubungula ukudla okulula zisebenzisa ama-food liner.
Njengoba eseneminyaka ecishe ibe ngu-20 embonini yemishini yokukhipha izinto ezihlakaniphile, ubelokhu ephethe izindima ezibalulekile eJwell Machinery, okuhlanganisa noMphathi Jikelele kanye noSihlalo Ojikelezayo. Kusukela ngo-2024, uphathe izinkampani eziningi ezingaphansi kwakhe, eqhuba ukwanda kwebhizinisi kanye nokuthuthukiswa kwezimboni, ngenkathi ehola ukusungula izinto ezintsha ekukhiqizeni izinto ezihlakaniphile kanye nokukhula komhlaba wonke.
