Zininzi izinto ezichaphazela i-ultrasonic ye-welding yeplastiki, kwaye siza kuthetha ngezinto ezikweli nqaku.
1. I-ultrasonic welding impahla eyahlukileyo
Umahluko we-welding we-welding uchaphazela umgangatho we-welding we-ultrasonic, ukongeza i-fiber kunye nezinye ukuzaliswa kunokuphucula ubulukhuni bezinto eziphathekayo, ezihambelana nokuhanjiswa kwe-ultrasonic, ukongeza iifayili kunokuphucula amandla e-ultrasonic welding joints phantsi kweemeko ezifanelekileyo zobuchwepheshe.
2. I-ultrasonic welding material surface roughness
Ukonyusa uburhabaxa bomphezulu akunakunciphisa kuphela i-acoustic impedance, ukuphucula ubuninzi bokuhamba kwamandla, kodwa kunokuphucula umgangatho we-welding we-ultrasonic.Ngokusebenzisa i-membrane yempahla kunye nephethini yokuqengqeleka phezu komhlaba, umgangatho ophezulu we-welding we-ultrasonic unokufumaneka, kwaye ngale ndlela, amandla e-ultrasonic welding joint ingaba phezulu amaxesha amaninzi kune-PP enye enomgangatho ogudileyo.
3. Ububanzi bomgca we-welding we-ultrasonic
Ukunyuka kobubanzi bomgca we-ultrasonic welding kunokunciphisa amandla e-ultrasonic welded joint;kuba ngokunyuka kwe-ultrasonic welding line ububanzi, uxinzelelo lwexinzelelo kwinqanaba le-ultrasonic welded joint liyanda, i-microcracks ibonakala kwinqanaba lokunyuka, kwaye amandla adibeneyo ayancipha.
4. Impembelelo yomgama ukusuka kwi-welding surface ukuya kwi-welding joint
Xa umgama ovela kwi-ultrasonic welding surface ukuya kwi-welding joint ifikelela kwixabiso le-half-wavelength, amandla e-ultrasonic welding joint afikelela kwinqanaba eliphezulu.I-Ultrasonic wave isasaza i-longitudinal-wave kwiiplastiki, kwaye ixabiso eliphakamileyo le-longitudinal-wave libonakala kakhulu kwisiqingatha sobude be-wave.Xa isondele kwisiqingatha se-wavelength, amandla okushisa amaza e-ultrasonic asasaza kwi-interface ye-welding ye-ultrasonic, kunye ne-ultrasonic welding joints inokufumaneka.Umgangatho we-ultrasonic welding uhambelana ngokuthe ngqo kwimodyuli ye-elastic, i-friction coefficient kunye ne-thermal conductivity, kunye nokulinganisa ngokungafaniyo nobuninzi bayo, ukushisa okuthe ngqo kunye ne-melting point.
I-5.Indawo yokunyibilika kunye nokuchasana kwe-friction ebusweni bezinto eziphathekayo
Isitshixo sekhwalithi ye-welding ye-ultrasonic ihambelana nendawo yokunyibilika kunye nokuchasana kwe-friction ebusweni bezinto eziphathekayo.Le parameter ayifani ngenxa yezixhobo ezahlukeneyo kunye nokushisa, ukuguqulwa kwabo kwinkqubo ye-welding ye-ultrasonic kuya kulimaza ubushushu, i-shear force kunye ne-deformation yendawo ye-welding ye-ultrasonic, kwaye ilimaza umgangatho we-ultrasonic welding.
Namhlanje, ezinye iiplastiki ezifana ne-PE, i-PC, i-ABS, i-PP, i-PVC, i-proline, i-nylon, i-polyester inokufumana umphumo ongcono kakhulu nge-welding ye-ultrasonic, ngoku ezi ziplastiki zisetyenziswa kakhulu kwiimarike.Emva kokuqonda oku ngasentla, sikholelwa ukuba i-ultrasonic mold yomshini we-welding we-ultrasonic inokukhetha ngokufanelekileyo izinto eziphathekayo, ukuphepha ukungaphumeleli okungadingekile, ukuphucula umgangatho wemveliso, ukunciphisa iindleko zokusebenza, kunye nokuphucula kakhulu ukusebenza kakuhle kwemveliso.
