Photosensitive resin, inowanzozivikanwa seUV inorapika isina shadowless adhesive, kana UV resin (inonamira), inonyanya kuumbwa neoligomer, photoinitiator uye diluent.Mumakore achangopfuura, photosensitive resin yakashandiswa muindasitiri iri kubuda ye3D kudhinda, iyo inofarirwa uye kukosheswa neindasitiri nekuda kwehunhu hwayo hwakanaka.Mubvunzo ndewokuti, photosensitive resin ine chepfu here?
Kugadzira musimboti we photosensitive resin: kana ultraviolet mwenje (chiedza chine imwe wavelength) ichivhenekera pane photosensitive resin, iyo photosensitive resin inoburitsa maitiro ekurapa uye shanduko kubva kumvura kuenda kune yakasimba.Inogona kudzora nzira yechiedza (SLA Technology) kana kudzora zvakananga chimiro chechiedza (DLP) tekinoroji yekurapa.Nenzira iyi, jira rekuporesa rinova muenzaniso.
Photosensitive resins anonyanya kushandiswa kudhinda mhando dzakanaka uye dzakaoma dhizaini modhi ine yakakwira zvinodiwa zvekurongeka kwemuenzaniso uye mhando yepamusoro, senge mabhodhi emaoko, akagadzirwa nemaoko, zvishongo kana zvikamu zvegungano.Zvisinei, hazvina kukodzera kudhinda mhando huru.Kana mhando dzakakura dzichida kudhindwa, dzinoda kuparadzaniswa kuti dzidhindwe.Nekudaro, zvinofanirwa kuyeuchidzwa kuti zvese zvinopenya uye zvakajeka kudhinda kunoda kukwenenzverwa mune inotevera nhanho.Iko kukwenenzverwa kusingasviki, kujeka kunenge kwatonyanya kuipa.
Photosensitive resin zvinhu hazvigone kungotaura kuti ine chepfu kana isina chepfu.Toxicity inofanira kukurukurwa pamwe chete nedosi.Kazhinji, hapana dambudziko mushure mekurapa kwechiedza.Chiedza chekurapa resin ndiyo matrix resin yechiedza chekurapa coating.Iyo inosanganiswa ne photoinitiator, inoshanda diluent uye zvakasiyana-siyana zvinowedzera kuumba chiedza chekuporesa coating.
Inoshanda UV monomer imhando yeacrylate monomer yakakodzera UV kurapa maitiro.HDDA ine yakaderera viscosity, yakasimba dilution simba, kuzvimba mhedzisiro papurasitiki substrate, uye inogona zvinobudirira kuvandudza nekusimudzira kunamatira kune epurasitiki substrate.Iyo ine yakanaka makemikari kuramba, kusamira kwemvura uye kupisa kupisa, yakanakisa mamiriro ekunze, yepakati reaction kumhanya uye yakanaka kuchinjika.UV monomers anoshandiswa zvakanyanya muUV coatings, UV ingi, UV anonamira uye mamwe minda.
UV monomer inowanzo ratidzwa ne low viscosity uye yakasimba dilution kugona;Yakanakisa kunamatira kune substrate yepurasitiki;Kudzivirira kwakanaka kwemakemikari, kudzivirira kwemvura uye kupisa kupisa;Excellent weather resistance;Kuchinja kwakanaka;Kumhanya kuri pakati nepakati;Kunyorova kwakanaka uye kuenzanisa.
Iyo UV monomer inogona kurapwa chete kana yavhenekerwa kune glue solution ne ultraviolet mwenje, kureva, iyo photosensitizer iri mune isina mumvuri inonamira inosungirirwa nemonomeri kana ichinge yafumurwa kune ultraviolet mwenje.Tichifunga, iyo isina mumvuri inonamira haipore kanenge nekusingaperi pasina mwenje we ultraviolet mwenje sosi.Ultraviolet mwaranzi inobva kuzuva rechisikigo uye magetsi ekugadzira magetsi.Iyo UV yakasimba, iyo inokurumidza kukurumidza kuporesa.Kazhinji, nguva yekurapa inotangira kubva pa10 kusvika ku60 seconds.Kuchiedza chezuva rechisikigo, iyo ultraviolet mwaranzi muzuva rinopisa ichave yakasimba, uye nekukurumidza kukurumidza kurapa kuri.Zvisinei, kana pasina chiedza chezuva chakasimba, chete artificial ultraviolet light source inogona kushandiswa.
Kune akawanda marudzi ezvakagadzirwa ultraviolet mwenje masosi, uye mutsauko wesimba zvakare wakakura kwazvo.Iyo yakaderera-simba inogona kuita diki sewatts mashoma, uye iyo yakakwirira-simba inogona kusvika makumi ezviuru zvewatts.Iyo yekumhanyisa yekurapa yekunamatira isina mumvuri inogadzirwa nevagadziri vakasiyana kana mhando dzakasiyana dzakasiyana.Iyo inonamira isina mumvuri inoshandiswa kusungirirana inogona kurapwa chete nechiedza chemwenje.Nokudaro, iyo inonamatira isina mumvuri inoshandiswa pakubatanidza inogona kungobatanidza zvinhu zviviri zvakajeka kana chimwe chazvo chinofanira kuva chakajeka, kuitira kuti chiedza che ultraviolet chipfuure uye chinopisa mvura inonamatira;Isa UV inonamira isina mumvuri kune imwe yenzvimbo, vhara ndege mbiri idzi, uye vhenekera nemwenje yeultraviolet ine wavelength yakakodzera (kazhinji 365nm-400nm) uye simba kana high-pressure mecury rambi rekuvhenekera.Kana irradiation, inofanirwa kuvhenekera kubva pakati kusvika kune periphery, uye kusimbisa kuti chiedza chinogona kupindira kune chikamu chekubatanidza.
