UV inki kudhinda kazhinji inotora nzira yekuomesesa UV kuomeswa, kuitira kuti iyo inki inogona kukurumidza kunamatira pamusoro peiyo firimu inonamira zvinhu. Nekudaro, mukudhinda, dambudziko rekusabatika kwakashata kweingi yeUV pamusoro pemafirimu ekuzvinamira zvinhu zvinowanzoitika.
Chii chakashata chekunamatira kweingi yeUV?
Materminal akasiyana ane nzira dzakasiyana dzekuyedza kusanamatira zvakanaka kweUV inki. Nekudaro, mune yekuzvinamira label indasitiri, vatengi vazhinji vachashandisa 3M 810 kana 3M 610 tepi yeinki adhesion bvunzo.
Kuongorora maitiro: Iko kusimba kweinki kunoongororwa maererano nehuwandu hweinki yakanamatira mushure mokunge tepi yekunamatira yakanamatira panzvimbo yezita uye yobva yabviswa.
Level 1: hapana inki inodonha
Level 2: Ingi diki inodonha (<10%)
Nhanho 3: yepakati inki kubuda (10% ~ 30%)
Nhanho 4: yakakomba inki yekudurura (30% ~ 60%)
Level 5: inenge yese inki inodonha (> 60%)
mubvunzo 1:
Mukugadzira, tinowanzosangana nedambudziko rekuti kana zvimwe zvinhu zvakadhindwa zvakajairika, iyo inki yekunamatira yakanaka, asi mushure mekumhanyisa kudhinda kunovandudzwa, iyo inki yekunamatira inowedzera.
chikonzero1:
Sezvo iyo photoinitiator iri muingi yeUV inobata mwenje weUV kuti igadzire mahara radicals, inoyambuka chinongedzo nemonomer prepolymer muchikamu cheinki kugadzira network chimiro, inova nhanho yenguva kubva kumvura kuenda kune yakasimba. Zvisinei, mukudhinda chaiko, kunyange zvazvo inki yepamusoro yakaomeswa pakarepo, zvakanga zvakaoma kuti chiedza che ultraviolet chipinde mukati meiki yakaomeswa pamusoro kuti isvike pasi, zvichikonzera kusakwana kwephotochemical kuita kweiki yepasi.
Zano:Kune yakadzika ingi uye chiedza kudhinda, yakakwirira ruvara simba inki inogona kushandiswa kuderedza ukobvu kweinki layer, iyo haigone kungoita kuti kuoma kwe-single-layer inki, asi zvakare zvinobudirira kuvandudza kugadzirwa kwakanaka.
chikonzero2:
Mwenje weUV mercury unowanzo shandiswa kwemaawa angangoita 1000, uye unogona kubatidzwa mushure mekunge mwenje weUV washandiswa kweanopfuura maawa 1000, asi ingi yeUV haigone kuoma zvachose. Muchokwadi, kana mwenje weUV wasvika pahupenyu hwayo hwesevhisi, iyo spectral curve yachinja. Iyo ultraviolet mwenje inoburitswa haina kusangana nezvinodiwa zveinki yakaoma, uye infrared simba yakawedzera, zvichikonzera deformation yezvinhu uye inki embrittlement nekuda kwekupisa kwakanyanya.
Zano:Nguva yekushandiswa kwemwenje weUV inofanirwa kurekodhwa nemazvo uye nekutsiviwa nenguva. Munguva yekugadzirwa kwakajairwa, zvakare zvinodiwa kugara uchitarisa kuchena kwemwenje weUV uye kuchenesa iyo reflector. Kazhinji, 1/3 chete yesimba remwenje weUV inopenya zvakananga pamusoro pezvinhu, uye 2/3 yesimba inoratidzwa neinoratidzira.
mubvunzo 2:
Mukugadzira, tinowanzosangana nedambudziko rekuti kana zvimwe zvinhu zvakadhindwa zvakajairika, iyo inki yekunamatira yakanaka, asi mushure mekumhanyisa kudhinda kunovandudzwa, iyo inki yekunamatira inowedzera.
Chikonzero 1:
Iyo ipfupi yekuonana nguva pakati peinki ne substrate inotungamira kune kusakwana kwema molecular level yekubatana pakati pezvimedu, zvichikanganisa kunamatira.
Zvimedu zveinki uye substrate zvinopararira uye zvinobatana kuti zvigadzire kubatanidza kwema molecular level. Nokuwedzera nguva yekuonana pakati peinki uye substrate isati yaoma, iyo yekubatanidza mhedzisiro pakati pemamorekuru inogona kuve yakakosha, nekudaro kuwedzera inki adhesion.
Suggestion: kuderedza kasi yekudhinda, ita kuti ingi ibatane zvizere ne substrate, uye uvandudze kunamatira kweinki.
Chikonzero 2:
isina kukwana UV chiedza kuratidzwa nguva, zvichiita kuti inki isina kuoma zvachose, inokanganisa kunamatira
Kuwedzerwa kwekumhanya kwekudhinda kuchapfupisawo nguva yekuvhenekesa kwechiedza cheUV, izvo zvinoderedza simba rinopenya painki, zvichikanganisa mamiriro ekuoma kweinki, zvichikonzera kunamatira kwakashata nekuda kwekuoma kusina kukwana.
Zano:Dzikisa kumhanya kwekudhinda, ita kuti ingi iome zvakazara pasi pechiedza cheUV, uye uvandudze kunamira.
