Ubudlelwane phakathi kohlobo lwamaza lombhobho womshicileli we-uv kunye ne-inki ye-uv lulolu hlobo lulandelayo: iifomati zamaza ezihambelana ne-inki ezahlukeneyo nazo zahlukile, ezichatshazelwa ikakhulu ngumahluko wesantya sesandi se-inki, i-viscosity ye-inki, kunye ukuxinana kwe-inki. Uninzi lwee-printheads zangoku zineemo zamaza eziguquguqukayo ukuze zilungelelanise ii-inki ezahlukeneyo.
Umsebenzi wefayile ye-nozzle waveform: ifayile ye-waveform yinkqubo yexesha lokwenza i-nozzle piezoelectric i-ceramic umsebenzi we-ceramic, ngokubanzi kukho ukuphakama okunyukayo (ukutshaja kwexesha lokucudisa), ixesha eliqhubekayo lokucudisa (ubude bokucudisa), umgca owelayo (ixesha lokukhupha), Ixesha elahlukileyo elinikiweyo liya kutshintsha ngokucacileyo amathontsi e-inki acudiswe ngumbhobho.
1.Ukuqhuba iMigaqo yoyilo lweWaveform
Uyilo lwamaza okuqhuba lubandakanya ukusetyenziswa komgaqo-siseko wezinto ezintathu zamaza. I-amplitude, i-frequency kunye nesigaba iya kuchaphazela umphumo wokugqibela we-piezoelectric sheet. Ubukhulu be-amplitude bunempembelelo kwisantya se-droplet ye-inki, ekulula ukuyiqonda nokuziva, kodwa impembelelo ye-frequency (ubude be-wavelength) kwisantya se-droplet ye-inki ayiyona inzulu kakhulu. Ngesiqhelo, olu lutshintsho lwegophe kunye nencopho ephezulu (elona xabiso lilungileyo) liyinketho, ngoko ke ixabiso elingcono kufuneka liqinisekiswe ngokweempawu ze-inki ezahlukeneyo ekusetyenzisweni okwenyani.
2. Impembelelo yesantya se-inki yesandi kwi-waveform
Ngokuqhelekileyo ngokukhawuleza kune-inki enzima. Isantya sesandi se-inki esekwe emanzini sikhulu kune-oyile. Kwintloko yoshicilelo efanayo, xa usebenzisa ingxinano eyohlukeneyo ye-inki, obona bude bamaza bufanelekileyo kwimo yayo yamaza kufuneka buhlengahlengiswe. Umzekelo, ububanzi be-wavelength yokuqhuba i-inki esekwe emanzini kufuneka bube buncinci kune-inki esekwe kwi-oyile.
3. Impembelelo ye-inki viscosity kwi-waveform
Xa umshicileli we-Uv eprinta kwimowudi yamanqaku amaninzi, emva kokuba i-wave wave yokuqhuba iphelile, kufuneka ime okwethutyana kwaye ithumele i-wave wave yesibini, kwaye xa i-wave wave yesibini iqala kuxhomekeke ku-oscillation yendalo yoxinzelelo lombhobho womphezulu emva i-waveform yokuqala iyaphela. Utshintsho lubola nje lube ngu-zero. (I-viscosity ye-inki eyahlukileyo iya kuchaphazela eli xesha lokubola, ngoko ke isiqinisekiso esibalulekileyo kwi-viscosity ye-inki ezinzileyo ukuze kuqinisekiswe ushicilelo oluzinzileyo), kwaye kungcono ukudibanisa xa isigaba singu-zero, ngaphandle koko ubude be-wavelength wave wesibini buya kutshintshwa. Ukuze kuqinisekiswe inkjet eqhelekileyo, kwakhona kwandisa ubunzima uhlengahlengiso best inkjet waveform.
4.Impembelelo yexabiso loxinaniso lwe-inki kwimo yamaza
Xa ixabiso loxinaniso lwe-inki lihlukile, isantya sayo sesandi sikwahlukile. Phantsi kwemeko yokuba ubungakanani bephepha le-piezoelectric lombhobho buchongiwe, ngokuqhelekileyo kuphela ubude be-pulse ububanzi be-wave wave okuqhubayo bunokutshintshwa ukuze kufumaneke eyona ndawo iphezulu ye-pulse peak.
Okwangoku, kukho imilomo enokuhla okuphezulu kwimarike yomshicileli we-UV. I-nozzle yasekuqaleni kunye nomgama we-8 mm iguqulwa ibe yi-waveform ephezulu ukuze iprinte i-2 cm. Nangona kunjalo, kwelinye icala, oku kuya kunciphisa kakhulu isantya soshicilelo. Kwelinye icala, iziphene ezinje nge-inki ephaphazelayo kunye nombala wokutyatyaza ziyakwenzeka rhoqo, nto leyo efuna umgangatho ophezulu wobugcisa wabavelisi bomshicileli we-uv.
