Ubuchwepheshe
Izinhlobo zezinto zepulasitiki ezisobala ezivame ukusetshenziswa emakethe yilezi: i-polymethyl methacrylate (ipulasitiki ye-acrylic noma i-plexiglass PMMA), i-polycarbonate (ipulasitiki ye-PC), i-polyethylene terephthalate (PET), inayiloni esobala, i-AS (i-Acrylonitrile-styrene copolymer) njll. amapulasitiki amathathu esichayeka kakhulu kuwo yi-PMMA, PC kanye ne-AS.
1. Izakhiwo zamapulasitiki asobala: okokuqala, amapulasitiki asobala kufanele abe nokucaca okuphezulu, futhi okwesibili kufanele abe namandla athile nokumelana nokugqoka, ukumelana nomthelela, ukumelana nokushisa, ukumelana namakhemikhali, nokumuncwa kwamanzi.Lapho isetshenziswa, yanelisa izimfuneko zokubonisa ngale futhi inokusebenza okuzinzile.
2. Izici zenqubo ye-PMMA.I-PMMA ine-viscosity ephezulu kanye ne-fluidity encane.Ngakho-ke, izinga lokushisa eliphezulu lempahla kanye nengcindezi ephezulu yomjovo kumele kusetshenziselwe ukubumba umjovo.Umthelela wokushisa komjovo mkhulu kunomfutho womjovo, kodwa ukwanda komfutho womjovo kuzosiza ukuthuthukisa izinga lokuncipha komkhiqizo.Ukumelana nomthelela ongemuhle, ukumelana nokugqokwa okungekuhle, ukunwaya kalula, ukushwabana kalula, ngakho-ke izinga lokushisa lesikhunta kufanele lenyuswe, futhi inqubo yokufingqa kufanele ithuthukiswe ukuze kunqotshwe lezi zinkinga.
3. Izici zenqubo ye-PC.I-PC ine-viscosity ephezulu, izinga lokushisa eliphezulu elincibilikayo kanye nokungabi namanzi, futhi ukukhiqizwa kwayo akukuhle njenge-PMMA.Ukucindezela komjovo kunomphumela omncane ku-fluidity, kodwa ngenxa ye-viscosity ephezulu, ingcindezi yomjovo isephezulu.Ngokufanayo, ukuze uvimbele ukucindezeleka kwangaphakathi, isikhathi sokubamba ingcindezi kufanele sibe mfushane ngangokunokwenzeka.Izinga le-shrinkage likhulu, ubukhulu buzinzile, kodwa ukucindezeleka kwangaphakathi komkhiqizo kukhulu, futhi kulula ukuqhekeka.
4. Izici zenqubo ye-PET.Izinga lokushisa lokubumba i-PET liphezulu, futhi uhla lokulungiswa kwezinga lokushisa lincane (260-300 ° C), kodwa ngemva kokuncibilika, linoketshezi oluhle, ngakho-ke ukwakheka kumpofu, futhi kuvame ukudingekile ukwengeza amadivaysi okulwa nokusabalalisa endaweni. umlomo wombhobho.Amandla emishini nokusebenza akuphakeme ngemva komjovo, futhi ukusebenza kufanele kuthuthukiswe ngenqubo yokwelula nokuguqulwa.
