Isistimu ye-infrared preheating devolatilization ukuze isuse iphunga ezintweni ezingavuthiwe
Uhlelo lwe-infrared preheating devolatilization lusebenzisa imisebe ye-infrared yobude obubekiwe ukuze kushise impahla eluhlaza yepulasitiki, njenge-PA6/PA66, PBT, PC, PLA, PET kanye ne-PETG,PP, PE njll.
Ingasetshenziselwa ukususa iphunga lempahla eluhlaza, ithuthukise ngempumelelo ikhwalithi yamapulangwe epulasitiki.
Ngemuva kokufinyelela izinga lokushisa esethiwe, izinto zokwakha zizoya kumojula ye-vacuum.Ukukhululwa kwezingxenye ze-colatile endaweni ye-cacuum kuyasheshiswa futhi ukomiswa kwe-desalination kuyakhishwa.
Izici zobuchwepheshe:
- Isakhiwo esilula, kulula ukusihlanza futhi sishintshe ngokushesha
- I-Degassing, inqubo yokomisa yokucubungula okuqhubekayo
- Ukususwa okuqondile kwesistimu ukuze kuncishiswe indawo yokusebenza
- Ukusebenza kahle okuphezulu nokonga amandla, u-60% wokonga njalo uma kuqhathaniswa nenqubo yokushisisa ngogesi.
- Ngemva kokwelashwa VOC okuqukethwe: <10ppm
- Ngemuva kokwelashwa kokuqukethwe komswakama:<150ppm
- Amandla okucubungula: 1-3 t/h
- Izinto ezingavuthiwe zingaba ezifanele: i-PA6/PA66, i-PBT, i-PC, i-PLA, i-PET ne-PETG, i-PP, i-PE njll.
Umshini ungasetshenziswa ekwakhiweni kwe-pelletizing eluhlaza (ukomisa nokuqeda amandla) nangemva kokumisa i-pelletizing eluhlaza kanye ne-devolatilization.
I-pretreatment ye-raw material (Ukomisa nokuqeda amandla) kanye nokoma kwama-pellets kanye nokuqeda amandla kuzothuthukisa ikhwalithi yamapulasitiki agaywa kabusha.
Noma yimuphi umbuzo, sicela usithinte ngokukhululekile.
Singanikeza imigqa egcwele yomshini wokwenza kabusha ipulasitiki, okuhlanganisa ukugaywa kwepulasitiki, ulayini wokuwasha kanye nomshini wokugaya.
Umshini wepulasitiki ogaywe kabusha kanye ne-granulating uhlobo lwempahla esetshenziswa ukugaywa kabusha imfucumfucu yepulasitiki ibe yizinhlayiyana noma ama-pellets angasetshenziswa kabusha ekwenzeni imikhiqizo emisha yepulasitiki.Umshini ngokuvamile usebenza ngokuhlikihla noma ukugaya udoti wepulasitiki ube izingcezu ezincane, bese uyancibilikisa futhi uwukhiphe ngedayidi ukuze wakhe ama-pellets noma ama-granules.
Kunezinhlobo ezahlukene zemishini yokugaywa kabusha yepulasitiki kanye ne-granulating etholakalayo, okuhlanganisa isikulufu esisodwa kanye nezikhiphi eziphuma ngamawele.Eminye imishini ihlanganisa izici ezengeziwe ezifana nezikrini zokususa ukungcola emfucumfucwini yepulasitiki noma izinhlelo zokupholisa ukuze kuqinisekiswe ukuthi ama-pellets aqina ngendlela efanele.Umshini wokuwasha amabhodlela we-PET, umugqa wokugeza izikhwama we-PP
Imishini yokugaywa kabusha kwepulasitiki kanye ne-granulating ivamise ukusetshenziswa ezimbonini ezikhiqiza udoti omkhulu wepulasitiki, njengokupakisha, ezezimoto, nezokwakha.Ngokwenza kabusha imfucumfucu yepulasitiki, le mishini isiza ukunciphisa umthelela wemvelo wokulahlwa kwepulasitiki futhi ilondoloze izinsiza ngokusebenzisa kabusha izinto ebezingalahlwa.
Imishini yokugaywa kabusha kwebhethri ye-lithium iwuhlobo lwempahla esetshenziswa ukuphinda igaywe futhi ithole izinto ezibalulekile kumabhethri e-lithium-ion, avame ukusetshenziswa kumishini kagesi efana nama-smartphone, amalaptop, nezimoto zikagesi.Okokusebenza ngokuvamile kusebenza ngokwephula amabhethri ezingxenyeni zawo, njenge-cathode nezinto ze-anode, isixazululo se-electrolyte, namafoil ensimbi, bese ehlukanisa futhi ehlanza lezi zinto ukuze ziphinde zisetshenziswe.
Kunezinhlobo ezahlukene zemishini yokuvuselela ibhethri ye-lithium etholakalayo, okuhlanganisa izinqubo ze-pyrometallurgical, izinqubo ze-hydrometallurgical, nezinqubo zemishini.Izinqubo ze-Pyrometallurgical zibandakanya ukucutshungulwa kwezinga lokushisa eliphezulu kwamabhethri ukuze kubuyiselwe izinsimbi ezifana nethusi, i-nickel, ne-cobalt.Izinqubo ze-Hydrometallurgical zisebenzisa izixazululo zamakhemikhali ukuze zihlakaze izingxenye zebhethri futhi zibuyisele izinsimbi, kuyilapho izinqubo zemishini zihilela ukuhlakazeka nokugaya amabhethri ukuze ahlukanise izinto.
Imishini yokugaywa kabusha kwebhethri ye-lithium ibalulekile ekwehliseni umthelela wemvelo wokulahlwa kwebhethri nokulondoloza izinsiza ngokuthola izinsimbi ezibalulekile nezinto ezingasetshenziswa kabusha kumabhethri amasha noma kweminye imikhiqizo.
Ngaphezu kwezinzuzo zokongiwa kwemvelo nezinsiza, okokusebenza kabusha kwebhethri le-lithium nakho kunezinzuzo zezomnotho.Ukuthola izinsimbi ezibalulekile nezinto ezisetshenziswayo kumabhethri asetshenzisiwe kunganciphisa izindleko zokukhiqiza amabhethri amasha, kuphinde kudale imizila yemali emisha yezinkampani ezibandakanyekayo enqubweni yokugaywa kabusha.
Ngaphezu kwalokho, ukwanda kwesidingo sezimoto zikagesi nezinye izinto zikagesi kuqhuba isidingo semboni esebenza kahle futhi esimeme yokugaywa kabusha kwamabhethri.Imishini yokugaywa kabusha kwebhethri ye-lithium ingasiza ukuhlangabezana nalesi sidingo ngokuhlinzeka ngendlela ethembekile nengabizi kakhulu yokuthola izinto ezibalulekile kumabhethri asetshenzisiwe.
Kodwa-ke, kubalulekile ukuqaphela ukuthi ukugaywa kabusha kwebhethri ye-lithium kuseyimboni entsha uma kuqhathaniswa, futhi kunezinselelo okufanele uzinqobe mayelana nokuthuthukisa izinqubo zokugaywa kabusha ezisebenza kahle nezingabizi.Ukwengeza, ukuphatha kahle kanye nokulahlwa kwemfucuza yebhethri kubalulekile ukuze kugwenywe izingozi zemvelo nempilo.Ngakho-ke, kufanele kube nemithethonqubo efanele kanye nezinyathelo zokuphepha ukuze kuqinisekiswe ukuphathwa kahle nokugaywa kabusha kwamabhethri e-lithium.
