Kuyini ukugeleza kwenqubo ye-umshini wokugaywa kabusha wepulasitiki?
Yiziphi izigaba zepulasitiki?
Kunezindlela eziningi zokuhlukanisa amapulasitiki.Ngokusho kwezakhiwo ezahlukene zomzimba namakhemikhali, amapulasitiki ahlanganisa amapulasitiki e-thermosetting kanye ne-thermoplastics.Ngokusho kobubanzi bokusetshenziswa kwamapulasitiki, amapulasitiki angahlukaniswa ngezigaba ezintathu: amapulasitiki ajwayelekile, amapulasitiki obunjiniyela, namapulasitiki akhethekile.
1. Amapulasitiki ajwayelekile
Lokhu okubizwa ngokuthi amapulasitiki enhloso ejwayelekile kubhekiselwa kulawo asetshenziselwa ukukhiqizwa ngobuningi bemikhiqizo yezimboni.Banokubunjwa okuhle kanye nenani eliphansi.Idala ukusetshenziswa okuningi kwezinto zokusetshenziswa zepulasitiki.
2. Amapulasitiki obunjiniyela
Amapulasitiki wobunjiniyela anezakhiwo ezinhle zemishini, ukuzinza okuhle kwe-dimensional, ukumelana nezinga lokushisa eliphezulu, kanye nokumelana nokugqwala kwamakhemikhali.Zisetshenziswa kakhulu ezakhiweni zobunjiniyela.Okufana ne-polyamide, i-polysulfone, njll. Ingasetshenziswa kabanzi ezidingweni zansuku zonke, imishini, nezimboni zikagesi.
3. Amapulasitiki akhethekile
Amapulasitiki akhethekile abhekisela kumapulasitiki anemisebenzi ekhethekile futhi angasetshenziswa emikhakheni ekhethekile.Amapulasitiki akhethekile anjengamapulasitiki aqhubayo, amapulasitiki asebenza ngozibuthe, nama-fluoroplastics, phakathi kwawo ama-fluoroplastic anezici ezinhle kakhulu zokuzigcoba kanye nokumelana nezinga lokushisa eliphezulu.
Kunjaniimishini yokugaywa kabusha yepulasitikikuhlukanisiwe?
Umshini wokwenza kabusha ipulasitikiyigama elijwayelekile lochungechunge lwemishini yokwenza ipulasitiki kanye nemishini yokugaywa kabusha yamapulasitiki alahlwayo, njengokuhlola nokuhlukanisa, ukuchotshozwa, ukuhlanza, ukomisa, ukuncibilika, ukwenza ipulasitiki, ukukhishwa, ukudweba ngocingo, imbudumbudu, njalonjalo.Ayibhekiseli emshinini othize kuphela kodwa isifinyezo semishini yokugaywa kabusha yepulasitiki, okuhlanganisa nemishini yokuhlanza ngaphambi kwesikhathi kanye nemishini yokugaywa kabusha kwe-pelletizing.Imishini yokwelapha ngaphambi kwesikhathi ihlukaniswe yaba yi-plastic crusher, i-ejenti yokuhlanza ipulasitiki, i-plastic dehydrator, nezinye izinto zokusebenza.Imishini ye-granulation nayo ihlukaniswe ngama-extruder epulasitiki kanye ne-plastic pelletizer.
Kuyini ukugeleza kwenqubo ye-umshini wokugaywa kabusha wepulasitiki?
Umshini wokugcwalisa udoti wepulasitikiingumshini wokwenza kabusha ofanele ukuphila kwansuku zonke namapulasitiki ezimboni.Inqubo yokugeleza iwukuba kuqala ufake amapulasitiki emfucumfucu ku-hopper bese uhambisa izinto ezizochotshozwa kusukela ebhandeni lokuthutha ukuya ku-crusher yepulasitiki.Ngemuva kwalokho, izinto ezisetshenziswayo kuqala zicutshungulwa ngokuchotshozwa, ukuwashwa kwamanzi, nokunye ukwelashwa, futhi izinto ezichotshoziwe zizodlula ku-conveyor yokuhlanza i-friction ukuze kuhlanzwe ukungqubuzana okuqinile.Okulandelayo, ithangi lokuwasha lizohlanza izingcezwana zepulasitiki ezingcolile ukuze kukhishwe ukungcola, futhi impahla izothuthelwa ethangini lokuwasha ngesixhumanisi esilandelayo ukuze ihlanzwe futhi.Ngemuva kwalokho, ithuba lokumisa likhipha amanzi futhi lomise izinto ezihlanziwe, futhi ithuba lokudla okuzenzakalelayo lizothumela izinto ezizofakwa emshinini oyinhloko we-granulator yepulasitiki ngendlela ehlelekile.Okokugcina, i-granulator yepulasitiki ingakwazi ukwenza i-granulate okokusebenza, futhi ithangi lokupholisa lizopholisa umucu wepulasitiki okhishwe kusifi.Imbudumbudu yepulasitiki ilawula usayizi wezinhlayiya zepulasitiki ngokulawula ukuguqulwa kwemvamisa.
Njengamanje, ukusetshenziswa kwamapulasitiki kukhulu emhlabeni wonke.Izindlela zokwelashwa zendabuko zokushiswa kanye nokulahlwa kwemfucuza yamapulasitiki azisifanele isimo samanje sokuthuthukiswa komhlaba.Ngakho-ke, lapho sisebenzisa imikhiqizo yepulasitiki ukuletha lula esintwini, sidinga futhi ukucabanga kabanzi ngokuthi singagaywa kanjani kabusha amapulasitiki angcolile asetshenzisiwe.Kusukela yasungulwa ngo-2018, iSuzhou Polytime Machinery Co., Ltd. isithuthuke yaba esinye sezisekelo zokukhiqiza ingqalasizinda emikhulu yaseChina futhi yaqongelela iminyaka eminingi yolwazi embonini yepulasitiki.Uma wenza udoti wokugaywa kabusha kwepulasitiki noma unenjongo yokuthenga, ungaqonda futhi ucabangele imikhiqizo yethu yekhwalithi ephezulu.
