Mehato ea Motheo ea Thermoforming
1. Tokisetso ea Lintho
Mohato oa pele ts'ebetsong ea thermoforming ke ho khetha le ho lokisa thepa e nepahetseng ea pampiri ea polasetiki. Lipampiri tse sebelisoang hangata li kenyelletsa Polystyrene (PS), Polyethylene Terephthalate (PET), High Impact Polystyrene (HIPS), Polypropylene (PP), le Polylactic Acid (PLA). Lisebelisoa tse fapaneng li na le thepa e fapaneng 'me li loketse lits'ebetso tse fapaneng. Khetho ea thepa ke motheo oa katleho ea ts'ebetso eohle, kahoo ho hlokahala tlhokomelo e khethehileng.
Lethathamo: Lisebelisoa tse Tloaelehileng tsa Thermoforming le Thepa ea tsona
| Lintho tse bonahalang | Kgutsufatso | Thepa | Likopo tse Tloaelehileng |
| Polystyrene | PS | E thata, e bonolo ho e sebetsa | Lisebelisoa tse lahliloeng, mabokose a ho paka |
| Polyethylene Terephthalate | PET | Ponaletso e phahameng, ho hanyetsa tšusumetso | Libotlolo tsa seno, sephutheloana sa lijo |
| Polystyrene e nang le tšusumetso e phahameng | MAHLAKO | Ho hanyetsa tšusumetso e matla, ho tiea ho hotle | Matlo a elektroniki, ho paka lijo tse hatselitsoeng |
| Polypropylene | PP | Ho hanyetsa mocheso o motle, botsitso ba lik'hemik'hale | Liphutheloana tsa lijo, liphutheloana tsa meriana |
| Asiti ea Polylactic | PLA | Biodegradable, eco-friendly | Lisebelisoa tse nang le moiteli, ho paka ka bio |
Nakong ea mokhahlelo oa ho lokisa thepa, bokaholimo ba lakane bo boetse bo hloka ho hloekisoa ho tlosa lerōle kapa litšila tse ka amang boleng ba ho bopa. Bakeng sa lits'ebetso tse itseng tse batloang haholo, lipampiri le tsona li ka hloka kalafo ea pele, joalo ka ho sebelisa li-anti-static agents kapa phetoho ea bokaholimo.
2. Ho futhumatsa
Ho futhumatsa ke e 'ngoe ea mehato ea bohlokoa ka ho fetisisa ts'ebetsong ea thermoforming, moo letlapa la polasetiki le futhumatsoang ho fihlela mocheso oa lona o bonolo, ho etsa hore e khonehe ka ho lekaneng. Lisebelisoa tsa ho futhumatsa hangata li sebelisa mocheso oa infrared kapa mocheso oa ho hanyetsa ho netefatsa hore lakane e futhumatsoa ka ho lekana.
Lisebelisoa tse fapaneng li hloka mocheso o fapaneng oa mocheso le linako. Ka mohlala, maqephe a PET hangata a hloka ho futhumatsoa ka har'a mocheso oa 120-160 ° C, ha maqephe a HIPS a hloka ho futhumatsa pakeng tsa 80-120 ° C. Mokhoa oa ho futhumatsa ha o hloke feela ho nahana ka ntlha ea ho nolofatsa thepa empa hape o tlameha ho etsa bonnete ba hore lakane ha e bole kapa e senyeha nakong ea mocheso. Ka hona, taolo e nepahetseng ea mocheso oa thepa ea ho futhumatsa ea hlokahala, 'me ho ka hlokahala hore ho pholisoe kapa ho lokisoe ha ho hlokahala.
Tlhahisong ea indasteri, ho ts'oana ha mocheso ho bohlokoa bakeng sa ho theha boleng. Haeba lakane e sa futhumatsoe ka ho lekana, e ka baka ho tsitsinyeha ha bokaholimo, ho tsieleha kapa ho fapana ha botenya sehlahisoa se felileng. Litaba tsena ha li ame feela ponahalo ea sehlahisoa empa hape li ka ama thepa ea eona ea mochini le ho tšoarella nako e telele. Ka hona, tlhokomelo e khethehileng e tlameha ho lefshoa ho ts'ebetsong ea lakane nakong ea ho futhumatsa.
3. Ho theha
Ho theha ke mokhoa oa ho fetisetsa pampiri ea polasetiki e futhumetseng ka har'a hlobo le ho sebelisa vacuum suction, khatello kapa matla a mochini ho e bopa. Mokhoa oa ho theha o ka aroloa ka ho etsa vacuum, ho theha khatello, le ho etsa mochini, e 'ngoe le e' ngoe e na le melemo le lits'ebetso tsa eona tse ikhethang.
Ha ho etsoa vacuum, lakane e khomaretsoe haufi-ufi le bokaholimo ba hlobo ho etsa sebopeho se lakatsehang. Mokhoa ona hangata o sebelisoa ho hlahisa lihlahisoa tse nang le mabota a masesaane joalo ka lisebelisoa tse lahloang le mabokose a pakang lijo. Khatello ea ho etsa likhatello tsa lakane ka har'a hlobo, e loketseng ho etsa lihlahisoa tse matla le tse rarahaneng. Ho etsa mechine ho sebelisa lisebelisoa tsa mochini ho kenya khatello ka kotloloho, haholo-holo e sebelisetsoang ho etsa lihlahisoa tse nang le marako a teteaneng.
Nakong ea ts'ebetso ea ho theha, litekanyetso tse kang khatello, nako le mocheso li hloka ho laoloa. Khatello e feteletseng e ka etsa hore lakane e phatlohe, athe khatello e sa lekaneng e ka baka libopeho tse sa fellang tsa sehlahisoa. Nako e telele ea ho bopa e ka baka botsofali ba lintho tse bonahalang, ha nako e khutšoanyane haholo e ka thibela tlhahiso e feletseng ea lintlha tsa sehlahisoa.
4. Ho pholisa
Ho pholisa ke mokhoa oa ho pholisa ka potlako sehlahisoa sa polasetiki se entsoeng ho ba boemong bo tiileng. Lebelo la ho pholisa le ama ka kotloloho botsitso ba sebopeho sa sehlahisoa le boleng ba bokaholimo. Ho pholisa hangata ho etsoa ho sebelisoa moea kapa metsi, ho latela sebopeho sa sehlahisoa, thepa, le litlhoko tsa katleho tsa tlhahiso.
5. Ho itšeha
Ka mor'a hore ho pholile ho phethoe, lihlahisoa tse entsoeng li hloka ho khaoloa ho tlosa likarolo tse feteletseng, ho etsa bonnete ba hore metse e hloekileng le e nepahetseng. Lihlahisoa tse sehiloeng li hloka tlhahlobo e eketsehileng ho netefatsa hore li kopana le litekanyo le libopeho tse hlokahalang.
6. Pokello ea Litšila
Litšila tse hlahisoang nakong ea ts'ebetso ea thermoforming, joalo ka likhahla le lihlahisoa tse nang le bothata, hangata li bokelloa bakeng sa ho sebelisoa hape. Sena ha se thuse feela ho fokotsa litšila tse tala empa hape se kopana le litlhoko tsa tikoloho. Ka mor'a ho bokelloa ha litšila, lisebelisoa tsena li ka boela tsa etsoa maqepheng a macha bakeng sa tlhahiso e tsoelang pele.
Moetsi oa litsebi oa mechini ea thermoforming.
