Ukucutshungulwa kwezinto zokusetshenziswa zepulasitiki ikakhulukazi inqubo yokuncibilika, ukugeleza nokupholisa izinhlayiya zenjoloba zibe yimikhiqizo eqediwe ngemva kokumiswa. Kuyinqubo yokufudumeza bese uyapholisa. Kuphinde kube yinqubo yokushintsha amapulasitiki asuke ezinhlayiyeni abe yizimo ezahlukene. Okweumshini wepulasitiki we-thermoforming , yonke inqubo ingenziwa ngokwezifiso ukuze isebenze ngokugcwele ngokuzenzakalelayo ngaphandle kokusebenza ngesandla, futhi ikhwalithi yomkhiqizo izinzile! Okulandelayo kuzochaza inqubo yokucubungula ngokombono wezigaba ezahlukene.
1. Ncibilikisa
I-heater yedivayisi ivumela izinhlayiya zezinto ezingavuthiwe ukuthi zincibilike kancane kancane zibe ukugeleza koketshezi. Izinto zokusetshenziswa ezihlukene zifaneleka kakhulu ukulawulwa kwezinga lokushisa. Ukwandisa izinga lokushisa kuzosheshisa ukugeleza kwezinto ezingavuthiwe, ezingakhuphula ukusebenza kahle, kodwa hhayi ukuqinisekisa isivuno. Kufanele kuzuzwe ibhalansi efanele. Ukwengeza, umphumela omuhle kanye nezici ze-PP uma kwenzeka ukuqhekeka okuphezulu kokushisa ukuthi kungcono ukwenza impahla eluhlaza igeleze ngokushelela ekufeni ngesikhathi sokukhiqiza, ukuze ugweme ukugcwaliswa okunganele noma i-reflux. I-Reflux isho ukuthi ukugeleza kwempahla eluhlaza kuyashesha kunezinga lokuphumayo, futhi ekugcineni kwandise ukusebenza kahle kokugeleza okumaphakathi, okulingana nokuthuthukiswa kwe-MFR. Ingenye yezindlela ezitholakalayo zokucubungula, Kodwa-ke, iphinde ibangele ukusatshalaliswa kwe-MFR okungavamile, okungase kuholele ekwenyukeni kokungazinzi kanye nezinga lokukhubazeka elandayo. Kodwa-ke, ngenxa yohlelo lokusebenza, imikhiqizo eqediwe ye-PP ayiwona imikhiqizo enembayo ephezulu, ngakho-ke umthelela awumkhulu.
2.Isiqu sesikulufa
Iningi lokucutshungulwa kwe-PP lincike kusikulufu ukuze sishayele uketshezi, ngakho-ke ukwakheka kwesikulufu kunomthelela omkhulu. Ububanzi buthinta okukhiphayo, futhi isilinganiso sokucindezela sithinta inani lokucindezela. Iphinde ibe nomthelela ekuphumeni nasekuqedweni komkhiqizo, okuhlanganisa umphumela wokuhlanganisa wezinto ezihlukahlukene (Color Masterbatch, izithasiselo nezilungisi). Ukugeleza kwezinto zokusetshenziswa kuncike kakhulu ku-heater, kodwa ukungqubuzana nokungqubuzana kwezinto ezingavuthiwe kuzophinde kukhiqize amandla okushisa okungqubuzana ukuze kusheshiswe uketshezi. Ngakho-ke, isilinganiso sokuminyanisa isikulufa sincane, ukugeleza kuncane, futhi isivinini esijikelezayo kufanele senyuswe, okuholela emandleni okushisa okungqubuzana amaningi kunesikulufu esinesilinganiso esikhulu sokucindezela. Ngakho-ke, ngokuvamile kuthiwa akukho nkosi ekusetshenzisweni kwepulasitiki, futhi umuntu oqonda ngokucophelela ukusebenza komshini yinkosi. Ukushisa kwezinto zokusetshenziswa akuyona nje i-heater, kodwa futhi kufaka phakathi ukushisa kwe-friction kanye nesikhathi sokuphefumula. Ngakho-ke, lokhu kuyinkinga engokoqobo. Okuhlangenwe nakho kuyasiza ukuxazulula izinkinga zokukhiqiza nokuthuthukisa ukusebenza kahle. Uma umphumela wokuhlanganisa wesikulufu muhle ngokukhethekile, ngezinye izikhathi izikulufu ezihlukene ezinezigaba ezimbili noma izikulufi ze-biaxial ziyaklanywa, futhi isigaba ngasinye sezinhlobo ezihlukene zezikulufi zisethwa ngokwehlukana ukuze kuzuzwe imiphumela ehlukahlukene yokuxuba.
3. Yifa noma ufe ngekhanda
Ukubunjwa kabusha kwepulasitiki kuncike kusikhunta noma ekhanda lokufa. Umkhiqizo oqediwe wokubumba umjovo unezinhlangothi ezintathu, kanti isikhunta sibuye sibe yinkimbinkimbi. Inkinga yokuncipha kufanele icatshangelwe. Eminye imikhiqizo indiza, strip kanye inaliti umkhiqizo okuqhubekayo dies. Uma kuyizimo ezikhethekile, zihlukaniswa njengezimo ezikhethekile. Kufanele kuqashelwe inkinga yokupholisa ngokushesha nokulinganisa. Imishini eminingi yepulasitiki iklanywe njengesirinji. Amandla e-extrusion aqhutshwa isikulufu azodala ingcindezi enkulu endaweni encane futhi athuthukise ukusebenza kahle kokukhiqiza. Lapho ikhanda lokufa liklanyelwe njengendiza, indlela yokwenza izinto zokusetshenziswa zisakazwe ngokulinganayo endaweni yonke, ukuklama kwekhanda le-hanger die head kubaluleke kakhulu. Naka ithuba le-extrusion lokwandisa iphampu ye-fish gill futhi uzinze ukunikezwa kwezinto zokusetshenziswa.
4. Ukupholisa
Ngaphezu kokuthela izinto zokusetshenziswa esangweni le-sprue, isikhunta sokujova sinomklamo wokupholisa izinto zokusetshenziswa esiteshini sokupholisa. Ukubumba kwe-Extrusion kuncike kumzila wamanzi wokupholisa kurola ukuze kuzuzwe umphumela wokupholisa. Ngaphezu kwalokho, kukhona nemimese yomoya, amanzi okupholisa acwiliswe ngokuqondile esikhwameni esiphephetha, ukuvuthela okungenalutho nezinye izindlela zokupholisa.
5. Nweba
Ukucutshungulwa kabusha komkhiqizo nokwandiswa kuzothuthukisa umphumela. Isibonelo, ijubane elihlukile lebhande lokupakisha eliqhutshwa ama-roller angaphambili nangemuva lizobangela umphumela wokunweba. Amandla aqinile wengxenye yokwandiswa komkhiqizo oqediwe ayaqiniswa, okungekho lula ukudabula, kodwa kulula kakhulu ukuklebhula ngokuvundlile. Ukusatshalaliswa kwesisindo samangqamuzana kuzophinde kuthinte umphumela wokunweba ekukhiqizeni ngesivinini esikhulu. Yonke imikhiqizo ekhishwe, okuhlanganisa imicu, inesandiso esingalingani. Ivacuum kanye nokwakhiwa komoya ocindezelwe nakho kungathathwa njengolunye uhlobo lwesandiso.
6. Nciphisa
Noma iyiphi impahla eluhlaza inenkinga yokuncipha, okubangelwa ukucindezeleka kwangaphakathi ngesikhathi sokwanda kokushisa, ukugoqa okubandayo kanye ne-crystallization. Ngokuvamile, ukunwebeka okushisayo kanye nokuncipha okubandayo kulula ukukunqoba, okungenziwa ngokwandisa isikhathi sokupholisa ekucubunguleni nasekugcineni ingcindezi ngokuqhubekayo. Izinto zokusetshenziswa zecrystalline zivame ukuba nomehluko omkhulu wokushwabana kunezinto ezingasetshenzisiwe ezingezona ikristalu, cishe u-16% we-PP, kodwa cishe u-4% we-ABS, ohluke kakhulu. Le ngxenye idinga ukunqotshwa kwisikhunta, noma izithasiselo zokunciphisa izinga lokuncipha kuvame ukungezwa, i-LDPE ivame ukungezwa ku-extrusion plate ukuze kuthuthukiswe inkinga yentamo.
Umshini wepulasitiki we-thermoforming isebenza cishe kuwo wonke ama-thermoplastics. Eminyakeni yamuva nje, umshini wepulasitiki we-thermoforming usetshenziswe ngempumelelo ukwenza amapulasitiki athile e-thermosetting. Umjikelezo wokubumba weumshini wepulasitiki we-thermoforming ifushane (imizuzwana embalwa ukuya emaminithini ambalwa), futhi ingakha isikhunta esinesimo esiyinkimbinkimbi, usayizi onembile futhi ngesikhathi esisodwa. Imikhiqizo yemishini ye-GTMSMART thermoforming ihlanganisaUmshini Wepulasitiki We-Thermoforming,Cup Thermoforming Machine,Umshini Wokwenza Ivacuum Yepulasitiki,Umshini Wokushisa Wembiza Yezimbali Yepulasitiki.
I-GTMSMART hlinzeka ngemishini yezinga lokuqala ngentengo evumayo engahlangabezana kalula nezidingo zakho zokukhiqiza ngobuningi. Hlola uhla lwethu lwemikhiqizo futhi uzothola izinketho eziningi ezisebenza kahle ezifanelana nezidingo zakho.
