Ngomongo wokuphrinta, ukulawulwa okwanele kwe-viscosity kayinki kungaholela ezinkingeni ezimbalwa zokusebenza?
2024-05-28
- I-Viscosity Edlulele: Uma i-viscosity kayinki iphezulu kakhulu, ukunamathela kwayo okungokwemvelo kanye nokuthambekela kokwenza imicu ende ngesikhathi sokudlulisa phakathi kwamarola kungase kubangele uyinki endizayo, isenzakalo lapho umucu ophukile uphela uhlakazeke emoyeni. Lo mphumela uba mubi kakhulu ngesikhathi sokuphrinta ngesivinini esikhulu.
- Ukulimala Kwephepha: I-viscosity ye-inki ephezulu ingadlula amandla angaphezulu ephepha, ibangele impushana, i-fibrillation, noma i-delamination, ikakhulukazi emaphepheni anezakhiwo ezixekethile namandla aphansi angaphezulu.
- Ukungasebenzi Kokudluliswa Kwe-ink: I-viscosity ephakeme ikhinyabeza ukudluliswa kwe-inki okuphumelelayo ukusuka kurola ukuya kurola kanye nokungena epuleti lokuphrinta noma i-substrate ngenxa yobudlelwano obuphambene phakathi kwezinga lokudlulisa uyinki kanye ne-viscosity. Lokhu kuholela ekusabalaliseni kukayinki ongalingani, ukufakwa kweyinki okunganele, nezikhala ezibonakalayo ezithombeni eziphrintiwe.
- Ukuphazamiseka Kwenqubo: I-viscosity ephezulu ayikhulisi nje kuphela ukusetshenziswa kukayinki futhi iholela ezingqimbeni zikayinki eziqinile ezinciphisa ukomisa, kodwa futhi kusiza 背面沾脏(ukuvalwa kukayinki) noma ukunamathela phakathi kwamashidi aphrintiwe. Ekuphrinteni okuphekelwe ishidi, kunengozi yokuthi iphepha lidonswe kumarola ayinki.
- Izinkinga Ze-Viscosity Ephansi: Ngokuphambene, uma i-viscosity kayinki iphansi kakhulu, ukukhuphuka kwe-fluidity (okubonakala njengokubukeka okuzacile) kukhuthaza ukufakwa kwe-inki ku-offset lithography, engcolisa ukuphrinta ngamamaki angahlosiwe.
- Ukusabalalisa Nokuncishiswa Okucacile: Oyinki abanjalo basakazeka kalula ephepheni, banweba indawo ephrintiwe, benciphisa ukucaca, futhi banciphise ukunamathela kanye nokucwebezela kwefilimu kayinki omisiwe endaweni engaphansi.
- I-Pigment Settling: I-viscosity enganele iyazabalaza ukuthwala izinhlayiya ze-pigment ezinkulu phakathi nokudluliselwa, okubangela lezi zinhlayiya ukuthi zinqwabelane kumarola, izingubo zokulala, noma amapuleti—isimo esaziwa ngokuthi i-piling.
