Kunezici eziningi ezithinta umphumela we-ultrasonic welding we-plastic, futhi sizokhuluma ngezinto ezikulesi sihloko.
1. Umehluko we-welding we-ultrasonic
Umehluko wezinto ze-welding uthinta ikhwalithi ye-welding ye-ultrasonic, ukwengeza i-fiber nokunye ukugcwaliswa kungathuthukisa ubulukhuni bezinto ezibonakalayo, okulungele ukuhanjiswa kwe-ultrasonic, ukwengeza ama-fillers kungathuthukisa amandla okuhlanganisa ama-welding we-ultrasonic ngaphansi kwezimo ezifanele zobuchwepheshe.
2. I-ultrasonic welding material surface roughness
Ukwandisa ubulukhuni bobuso akukwazi nje ukunciphisa i-acoustic impedance, ukuthuthukisa ukuminyana kwamandla okugeleza kwamanzi, kodwa futhi kungathuthukisa ikhwalithi ye-welding ye-ultrasonic.Ngokusebenzisa i-membrane impahla enephethini egoqayo ebusweni, ikhwalithi ephakeme ye-welding ye-ultrasonic ingatholakala, futhi ngale ndlela, amandla okuhlanganiswa kwe-welding ye-ultrasonic angaba ngaphezulu izikhathi eziningana kune-PP eyodwa enendawo ebushelelezi.
3. Ububanzi bomugqa we-welding we-ultrasonic
Ukwanda kobubanzi bomugqa we-welding we-ultrasonic kunganciphisa amandla e-ultrasonic welded joint;ngoba ngokwanda kobubanzi bomugqa we-welding we-ultrasonic, ukuhlushwa kokucindezeleka emaphethelweni okuhlanganiswa kwe-ultrasonic welded kuyanda, ama-microcracks avela ekukhuphukeni komkhawulo, futhi amandla ahlangene ayancipha.
4. Umthelela webanga ukusuka endaweni ye-welding kuya ekuhlanganyeleni kokushisela
Lapho ibanga elisuka endaweni ye-welding ye-ultrasonic kuya ekuhlanganyeleni kwe-welding lifinyelela inani le-half-wavelength, amandla e-ultrasonic welding joint afinyelela phezulu.Igagasi le-Ultrasonic ikakhulukazi lisakaza i-longitudinal-wave kumapulasitiki, futhi inani eliphakeme legagasi le-longitudinal eliphakeme kakhulu livela kuhhafu wamaza amaza.Uma isiseduze nesigamu se-wavelength, amandla okushisa amagagasi e-ultrasonic asakaza ku-interface ye-welding ye-ultrasonic, futhi amalunga amahle we-welding we-ultrasonic angatholakala.Izinga le-welding ye-ultrasonic lilingana ngokuqondile ne-elastic modulus, i-friction coefficient kanye ne-thermal conductivity, futhi ngokuphambene ngokulingana nobuningi bayo, ukushisa okuqondile kanye nendawo yokuncibilika.
5.Iphuzu lokuncibilika kanye nokumelana nokungqubuzana kwendawo yezinto
Isihluthulelo sekhwalithi ye-welding ye-ultrasonic ihlobene nephuzu lokuncibilika kanye nokumelana nokungqubuzana kwendawo yezinto ezibonakalayo.Le parameter ayifani ngenxa yezinto ezihlukene nezinga lokushisa, ukuguqulwa kwabo kwinqubo ye-welding ye-ultrasonic kuzolimaza izinga lokushisa, i-shear force kanye nokuguqulwa kwendawo ye-welding ye-ultrasonic, bese ilimaza ikhwalithi ye-welding ye-ultrasonic.
Namuhla, amanye amapulasitiki afana ne-PE, i-PC, i-ABS, i-PP, i-PVC, i-proline, inayiloni, i-polyester ingathola umphumela omuhle kakhulu nge-welding ye-ultrasonic, manje lawa mapulasitiki nawo asetshenziswa emakethe kakhulu.Ngemuva kokuqonda okungenhla, sikholelwa ukuthi isikhunta se-ultrasonic somshini wokushisela we-ultrasonic singakhetha ngokufanelekile izinto, sigweme ukwehluleka okungadingekile, sithuthukise ikhwalithi yomkhiqizo, sinciphise izindleko zokusebenza, futhi sithuthukise kakhulu ukusebenza kahle kokukhiqiza.
