Kuyini ukwelashwa kwe-inki futhi kungani kubalulekile?

Umgomo oyisisekelo wokuphrinta ukuphulukiswa kwe-inki ukuqina kweyinki ewuketshezi nokwakhiwa kwefilimu eqinile enamathiselwe ku-substrate. Ukuphulukisa, ngokungafani nokomisa okulula, lapho inqubo incike ekuhwamukani kwe-solvent, ukusabela kwamakhemikhali, okuvame ukusabela kwe-photo-polymerization noma ukusabela okuxhumanisayo, okudala inethiwekhi eqinile ye-polymer.

Kubalulekile ukwazi umehluko phakathi kokumiswa kwe-inki nokwelashwa:

• Ukomisa i-inki: Ngokuyinhloko ukomisa i-solvent noma ukomisa i-oxidative.
• Inqubo yokuphrinta ebandakanya izibopho zamangqamuzana ezingapheli ngokusebenzisa i-polymerization yamakhemikhali.

Ama-monomers nama-oligomers asabela ngesikhathi senqubo yokuphulukisa ngaphansi kokuchayeka kwamandla okulawulwayo ukwakha inethiwekhi ye-polymer. Lokhu kuholela ku:

• Ukuthuthukiswa kobulukhuni bendawo.
• Ukuqinisa ukunamathela kwe-inki.
• Ukwandisa ukumelana nokuklwebha.
• Amakhono okumelana namakhemikhali.
• Ukwandisa ukuqina kokuphrinta.

Uma kungekho ukwelashwa, izinkinga ze-tack ebusweni zizovela, kanye nokusebenza okungalungile kwamandla esibopho nokumelana okuphansi kwe-abrasion.

Iyini inqubo yokuphulukisa inki embonini yokunyathelisa?

Umbuzo ochwepheshe abaningi abawubuza ukuthi ukwelashwa kwe-inki kusebenza kanjani ekunyatheliseni kwezimboni. Isixazululo sitholakala ekusebenzeni kwamandla. Ukuphulukisa i-kinetics ekuphulukini kwezimboni kuvame ukubangelwa amandla, imvamisa ukukhanya kwe-UV, ukushisa kwe-infrared, noma ukuchayeka okushisayo. Lokhu kuqalisa:

• Photo-initiated cure
• Ukusabela okuxhumanisa isiphambano
• Ukulungiswa kwesilinganiso sokuphendula
• Ukuncishiswa kwe-tack ebusweni
• Ukulawulwa okugcwele kwe-vs surface ukwelashwa.

Ama-photo-initiators ku-UV ukuphulukisa inkinobho amunca imisebe ye-UV wavelength (365 nm, 385 nm, 395 nm, 405 nm) lapho ingaphansi kwemisebe ye-ultraviolet. Lokhu kwakha izinhlobo ezisebenzayo eziqala i-polymerize ngokushesha- imvamisa ngama-milliseconds.

Imishini yokwelapha yezimboni ihloselwe ukuqinisekisa ukuthi:

• Ukulawula isikhathi sokuhlala
• Ukuhambisana kwejubane lomugqa
• Ukulawulwa kokuvimbela i-oksijini

Le mingcele inomthelela oqondile ekujuleni kokungena kokuphulukisa kanye nokusebenza kokugcina kokunamathela kweyinki.

Significant Ink Curing Technology Large-Scale

Ukuphulukiswa kwe-UV kuyindinganiso engcono kakhulu yohlelo lokuphulukisa ngesivinini esiphezulu. Inikeza:

• Ukwelashwa okusheshayo
• Akukho ukuhwamuka kwe-solvent
• Ukukhishwa kwe-VOC kuncishisiwe
• Ubuchwepheshe bokwelapha - okonga amandla.

Ubuchwepheshe obujwayelekile bokuphulukisa isibani se-UV bubandakanya ukusetshenziswa kwezibani ze-mercury vapor ezikhiqiza ububanzi obubanzi bokukhanya kwe-UV. Kodwa-ke, izinhlelo ezindala zishintshwa ngokushesha ngezinhlelo zokuphulukisa ze-LED UV ngenxa yalokhu:

• Nciphisa amandla asetshenziswa ekwelapheni.
• Ukukhiqizwa kokushisa okuncishisiwe
• Isikhathi eside sokusebenza
• Ukulawulwa kwe-irradiance okuzinzile

Ukuphulukiswa kwe-inki ye-LED

Ukusetshenziswa kwe-LED ink curing inikeza ibhendi emincane ye-UV (isb., 365nm noma i-395nm) ukuthuthukisa ukulawulwa kokuqina kokwelapha nokunciphisa izinkinga zokuphathwa komthwalo oshisayo. Kwandisa ukuhambisana kwama-substrates, ikakhulukazi:

• Ukuphulukiswa kwepulasitiki substrate inki
• Ukupakisha okusekelwe kwifilimu
• Izinto ezizwela ukushisa

Ukuphulukiswa kwe-Thermal Ink

Ukushisa okulawulwayo ku- ukuphulukisa umhubhe kuhhavini noma kuhhavini wokuphulukisa kusetshenziswa ku-polymerization ezishisayo. Le nqubo ijwayelekile yokuphulukisa i-offset nokuqedwa kwezimboni kepha isebenzisa amandla amaningi.

Ukuphulukiswa kwe-inki ye-infrared

Ukomisa kwe-oxidative kanye nokuhwamuka kwe-solvent. Ukuphulukiswa kokushisa kwe-infrared kuyashesha kunokuphulukisa, futhi kufanelekile kwezinye izinhlelo zokusebenza zokuphulukisa ze-flexographic kanye nokuphrinta kwesikrini.

Ukuphulukiswa kogongolo lwe-electron

Ukuphulukiswa kogongolo lwe-electron kukhululekile kuma-solvents futhi kusebenza kahle kakhulu; noma kunjalo, inezindleko ezibizayo zemishini nemithetho yokuphepha.

Autonomous Ink Curing Uses in the Industry

• Ukupakisha Ink Ukuphulukisa

Isetshenziswe kabanzi ekwelapheni ukupakisha ukudla, kufanele ibe nokufuduka okuphansi nezimfanelo eziphezulu zokumelana namakhemikhali.

• Ukuphrinta Ilebula Ukuphulukiswa Kweyinki

Idinga ukuminyana kombala kanye nokuthuthukiswa kwezinga le-gloss elithuthukisiwe ku-brand njengekhwalithi ephezulu.

• Textile Ink Ukuphulukiswa

Iqinisekisa ukuguquguquka, ukumelana nokugeza, nokuqina.

• Ukuphulukiswa kwe-Plastic Substrate Ink

Kudinga ukukhiqizwa kokushisa okuphansi nokunamathela okuphezulu kwe-substrate.

• Metal Surface Ink Ukuphulukiswa

Ukusebenza okuphezulu kakhulu kwamandla esibopho nokumelana nokugqwala.

Quick Drying Inks in Rapid Printing

Ukusethwa kokukhiqizwa kwevolumu ephezulu kudinga ukwelashwa okusheshayo kweyinki ngokushesha, nangesikhathi sokuphumula esinganakiwe. Izinhlelo zokuphulukisa ze-UV ze-LED zinokufudumala okufushane, futhi zingasetshenziswa njengalezo ezisheshayo, okusho ukuthi akukho ukubambezeleka kokukhiqiza.

Ukwelashwa okuphumelelayo kokuphrinta kukhuthaza iqiniso lokuthi abakhiqizi bangakwazi ukwandisa ukusebenza kwabo ngaphandle kokunciphisa impilo yokuphrinta.

Gxila ekuqambeni: I-UV LED Curing Pen

Ngenkathi izinhlelo ezinkulu zokuphulukisa zilawula ukukhiqizwa kwezimboni, izinhlelo zokusebenza eziningi zikhona ezidinga ukuhamba nokunemba. Yilapho i-UV et LED Curing Pen ye-UVET ingena khona.

Le UV LED Curing Pen iyithuluzi elihlangene kodwa elinamandla elitholakala ku-UVET, elisetshenziselwa ukwelapha izinto ezizwela ukukhanya. Ikhiqiza ukukhanya kwe-UV ku-365nm, 385nm, 395nm, noma i-405nm, ngakho-ke iyahambisana nezinhlobonhlobo ezinkulu zokunamathisela okusebenzayo kwe-UV nokuqeda.

Izici ezisemqoka

• Ukumiswa okuncane, ukusetha okulula.
• Inikwe amandla yibhethri le-Li-ion (uma nje amahora ama-2 wokusebenza okuqhubekayo).
• Inkinobho yamandla ephezulu kufanele ibe nembile futhi ingasetshenziswa ngesandla esisodwa.
• Amamodeli we-6 amalensi e-optical aguqukayo.
• Ukuvulwa kwe-LED okusheshayo
• Ukukhiqizwa kokukhanya okuzinzile, okungaguquguquki.

Kungani i-UV LED Curing Pen iyisinqumo esihle kakhulu?

Le divayisi inezinzuzo ezithile ngaphezu kohlelo lwendabuko lokuphulukisa isibani se-UV, okufaka:

• Akukho ukushisa noma ukusebenza kokwelapha okusheshayo.
• Ukuphulukiswa kwe-kinetic reproducible.
• Ukukhiqizwa kokushisa okuphansi okulondoloza ama-substrates abuthakathaka.
• Umklamo omncane we-ergonomic ozosetshenziswa ngesandla isikhathi eside.

Ukukhethwa kohlelo oluhle kakhulu lokuphulukisa i-inki ongasetshenziswa ekushicileleni kwesikrini

Uma uqhathanisa uhlelo oluhle kakhulu lokuphulukisa ongalusebenzisa ngesikhathi sokuphrinta kwesikrini, cabanga:

• Isilinganiso sokushisa sokuphulukisa esidingekayo.
• Ukuhambisana kwe-substrate
• Ukuhambisana kwejubane lomugqa
• Ukuphathwa komthwalo wokushisa
• Ukulawulwa kokuvimbela i-oksijini

Ukupakisha nokuphrinta amalebula, ukusetshenziswa kwe-UV LED ink curing embonini yokupakisha kuzohlinzeka ngokusebenza okungcono futhi kudle amandla amancane.

Isiphetho:

Inqubo yokuphulukisa  inki akuyona inqubo elula yokuqeda, kepha kunalokho isayensi yobunjiniyela, amakhemikhali nokunemba. Njengoba kukhona ukuphulukiswa kwe-UV, ukuphulukiswa kwe-LED, nokuphulukiswa okushisayo ne-infrared, ngayinye yazo ibalulekile ekukhiqizeni izimboni. Udinga izinhlelo zokuphulukisa ngesivinini esiphezulu ukupakisha ingxenye enkulu yomkhiqizo wakho noma ithuluzi le-UV LED eliphathwayo ukubopha ngokunemba. UVET inikeza imishini emisha yokufeza ukusebenza okuphezulu nokuthembekile kokuphulukisa esikhathini esizayo.
