Chii chinonzi UV inorapika resin?

Chiedza chekuporesa resin inoumbwa nemonomer uye oligomer, iyo ine mapoka anoshanda anoshanda uye inogona kuvepolymerized nemwenje initiator pasi pe ultraviolet mwenje kuti igadzire isinganyungudika firimu.Photocurable resin, inozivikanwawo se photosensitive resin, ndeye oligomer iyo inogona kuitika mumuviri uye makemikari shanduko munguva pfupi mushure mekuratidzwa kuchiedza, uye ipapo crosslink uye kurapa.UV inorapika resinimhando yephotosensitive resin ine yakaderera hama molecular huremu, iyo ine reactive mapoka anogona kuve UV kurapika, senge unsaturated kaviri bond kana epoxy mapoka.UV inorapika resin ndiyo matrix resin yeUV inorapika coatings.Iyo inosanganiswa nemafotoinitiators, anoshanda diluents uye akasiyana ekuwedzera kuti aumbe UV anorapika machira.

Chiedza chekuporesa resin inoumbwa ne resin monomer uye oligomer, iyo ine inoshanda inoshanda mapoka.Inogona kuve polymerized nemwenje initiator pasi pe ultraviolet mwenje kuti igadzire isinganyungudika firimu.Bisphenol A epoxy acrylateine maitiro ekukurumidza kuporesa kukurumidza, yakanaka makemikari anonyungudutsa kuramba uye kuoma kwakanyanya.Polyurethane acrylateine hunhu hwekuchinjika kwakanaka uye kupfeka kuramba.Chiedza chakarapwa composite resin inowanzoshandiswa kuzadza uye kugadzirisa zvinhu mu stomatology.Nekuda kweruvara rwayo rwakanaka uye rimwe simba rekumanikidza, inoita basa rakakosha mukushandiswa kwekiriniki.Takawana mhedzisiro inogutsa mukugadzirisa kuremara kwakasiyana-siyana uye cavities yemazino epamberi.

Iyo UV inorapika coating inzvimbo-inoshamwaridzika-yekuchengetedza simba coating yakagadziriswa neBayer Kambani kuGermany mukupera kwema1960.China yapinda mumunda weUV inorapika coatingskubva kuma1980.Pakutanga, kugadzirwa kweUV curring resin kwainyanya kugadzirwa nemakambani akaita seAmerican Sadoma, Japanese Synthetic, German Bayer neTaiwan Changxing.Ikozvino, vazhinji vagadziri vepamba vari kuita zvakanaka, seSanmu Group uye Zicai Chemical.Mumakore achangopfuura, nekuvandudzwa kwekuziva kwevanhu nezvekuchengetedza simba uye kuchengetedza kwezvakatipoteredza, kushanda kwakasiyana-siyana kweUV inorapika majasi kwakaramba kuchiwedzerwa, nzvimbo yekushandisa yakawedzerwa, uye kubuda kwakawedzera nekukurumidza, zvichiratidza kukurumidza kusimudzira.Kunyanya mushure mekunge machira aiswa muchikamu chekuunganidza mutero wekushandisa, kuvandudzwa kweUV resin [1] inotarisirwa kuwedzera kukurumidza.UV anorapika machira haangoshandiswa zvakanyanya mumapepa, mapurasitiki, matehwe, simbi, girazi, ceramics uye mamwe ma substrates, asi zvakare akabudirira kushandiswa mune optical fiber, yakadhindwa redunhu bhodhi, yemagetsi chikamu kurongedza uye zvimwe zvinhu.
