Mundima yekudhinda, iyo inki inoshandiswa kudhinda yakaratidzawo zvinoenderana nezvinodiwa, UV inki yekukurumidza kurapwa, kuchengetedza kwezvakatipoteredza uye zvimwe zvakanakira indasitiri yekudhinda.UV yekudhinda inki mukati mekudhinda kudhinda, letterpress, kudhinda kwegravure, kudhinda skrini uye inkjet kudhinda uye mamwe minda yekudhinda, chinyorwa ichi chinogovera UV ink ine ruzivo ruzivo, zvirimo kune shamwari referensi:

Tsanangudzo

UV: Ipfupi kune ultraviolet mwenje.Ultraviolet (UV) haioneki nemaziso.Icho chikamu chemagetsi emagetsi emagetsi kunze kwechiedza chinooneka chepepuru.Iyo wavelength iri muhuwandu hwe10 ~ 400nm

UV inki: UV inki, inoreva UV mwenje irradiation pakarepo inorapa inki

Hunhu

1, iyo yekuomesa kumhanya inokurumidza, chengetedza nguva, pasi peUV mwenje irradiation, inoda masekondi mashoma kusvika mashoma anogona kurapwa.

2, michina inovhara nzvimbo yediki, kudhinda kuyerera kwekushanda, kuchengetedza manpower, hupfumi mabhenefiti.

3, kupfuura chero ingi kunze kweiyo evaporation yekuomesa inki, inogona kuchengetedza simba.

4, kana iri iyo yakafanana yakaoma firimu ukobvu, yakawanda inki kuchengetedza.

5, haizoome, chero ukasabata ultraviolet mwaranzi isingaome yakasimba painki.

6, kunaka kwemavara kugadzikana.

7, kupenya kwepamusoro.

8, inki zvidimbu zvidiki, inogona kudhinda yakanaka mapatani.

9, kudhinda nharaunda mweya mutsva, kunhuhwirira kudiki, hakuna VOC.

Main ingredients

Izvo zvakakosha zveUV inki zvinosanganisira pigment, oligomer, monomer (inoshanda diluent), photoinitiator uye akasiyana anobatsira.Pakati pavo, resin uye inoshanda diluent inoita basa rekugadzirisa pigment uye kupa firimu kugadzira zvivakwa;Pigment inopa inki ine mwero ruvara uye kuvhara simba kune substrate;Photoinitiator inodiwa kuti ikwanise kutora mafotoni pasi pekukanganiswa kwe pigment kuti itange polymerization.

1, Monomolecular Compounds (reactive diluent)

Uyu musanganiswa wakapfava une huremu hudiki hwemamorekuru, unogona kuderedza viscosity, kuita basa rekuparadzira, unogona kuparadzira pigment, kunyungudutsa resin, kuona kumhanya kwekurapa uye kunamatira kweinki, uye kutora chikamu muUV resin kurapa crosslinking reaction.

2, Zvinowedzera

Kusanganisira pigments, lubricant, thickening agent, filler, solidifying agent, etc. Inokanganisa inki gloss, viscosity, kupfava, ruvara, firimu gobvu, kukurumidza kuporesa, kukodzera kudhinda uye zvimwe zvinhu.

3, Chiedza Solid Resin ndiyo UV Ink Inobatanidza Material

UV inki yekurapa kumhanya, gloss, adhesion, friction resistance uye zvimwe zvivakwa, inki yakasiyana ine marudzi akasiyana emusanganiswa resin.

4, Chiedza Initiator

Chiedza chinotanga sebhiriji pakati pemakemikari reaction, imhando yekukurudzira kwechiedza kunoshanda zvakanyanya, mushure mekutora mafotoni kuburitsa emahara radicals, mahara radical kuendesa simba kune mamwe mafotosensitive polymer, inoburitsa ketani yekuita, iyo imwechete mamorekuru zvinhu, kuwedzera, mwenje yakasimba resin. pamwe chete, ita ingi kuporesa maitiro, uye mushure mekusunungurwa kwesimba pachayo haina kubatanidzwa mukusangana kwekuita.

Solidification Principle

Pasi pekuvhenekesa kwechiedza che ultraviolet, mwenje wekutanga kunyudza simba kugadzira mahara radicals, mahara radical chiitiko pakumhanya kwakanyanya, kudhumhana kunoitika neresin uye imwechete molecular compound, kuendeswa kwesimba kune resin uye imwechete mamorekuru makomisheni, resin uye imwe chete molecular compound. mushure mekutora simba rekusimudzira rine unsaturated kaviri bond maatomu polymerized monomer polymer uye radicals, kureva, resin uye imwechete molecule makomisheni, Vanovhura iyo mbiri bond uye vanotanga kuchinjika-kubatanidza maitiro, muchinjiko wekubatanidza kurapa, umo iyo photoinitiator inorasikirwa nesimba uye inodzoka. kumamiriro ayo epakutanga.

Zvinhu Zvinokanganisa

UV yekurapa inki inofanirwa kuve neUV mwenje kurapa, zvikasadaro haigone kushandiswa.Mukushandiswa kweinki yeUV, dambudziko rekutanga rekunamatira nderekuti UV inki haina kudzika kurapa.Panyaya yemidziyo yakasimba yakasimba, chikonzero chinogona kunge chiri kutadza kwemidziyo yekurapa UV, kureva kuti, wavelength yemhando yeUV yekurapa haienderane neUV mwenje wakasimba inki, kana simba rakasimba harina kukwana, kana mwenje wakasimba kumhanya hauna. zvakakodzera.

1, chiedza chakasimba ingi UV chiedza chakasimba chinotaridzika senitivity renji yewavelength pakati pe180-420NM.

2, simba remwenje weUV rinofanirwa kusangana nezvinodiwa zvetekinoroji zvekupora inki.

3, kukurumidza kudhinda nekukasira kunokanganisawo kumhanya kwekupora kweinki.

4, pesvedzero yehukobvu hweinki, inki yakawandisa inokanganisa kurapa, zvese zvinokanganisa kukora kwefirimu rekudhinda zvinokanganisa kurapa.

5, kukanganisa kwemamiriro ekunze: kupisa kwakanyanya, UV inki viscosity inova yakaderera, mushure mekudhinda, nyore kugadzira paste vhezheni chiitiko.Tembiricha yakaderera, yakakwira viscosity, inokanganisa thixotropy yeinki, tembiricha yewekishopu haigone kunge yakakwira zvakanyanya, munguva yechando muimba yekuchengetera mhepo yekuchengetera mhepo, inofanira kuiswa kune tembiricha yekamuri, uye yakakodzera kunonoka kukurumidza kurapa.

6, pesvedzero yepigment pane UV inki: nekuda kweakasiyana pigment pakunyudzwa kwechiedza, kuratidza uye pigment yemukati inki kazhinji, chena, dema, bhuruu zvakanyanya kunetsa kurapa, tsvuku, yero, mafuta akareruka, mafuta akajeka ari nyore kurapa. .
