Nekuda kwemabhenefiti ekurapa nekukurumidza, kuchengetedza simba uye kuchengetedza kwezvakatipoteredza, chiedza chekuporesa zvigadzirwa zvinoshandiswa zvakanyanya munzvimbo dzakasiyana siyana.Vakatanga kunyanya kushandiswa mumunda wekuputira huni.Mumakore achangopfuura, nekuvandudzwa kwevatangi vatsva, diluent anoshanda uye photosensitive oligomers, kushandiswa kweUV machira anorapika kwakawedzera zvishoma nezvishoma kusvika kuminda yemapepa, mapurasitiki, simbi, machira, zvikamu zvemotokari uye zvichingodaro.Izvi zvinotevera zvinosuma muchidimbu mashandisirwo ematekinoroji akati wandei ekurapa mwenje munzvimbo dzakasiyana.
UV kurapa 3D kudhinda
Chiedza chekurapa 3D kudhinda ndeimwe yeanokurumidza prototyping tekinoroji ine yakanyanya kudhinda iko uye kushambadzira.Iyo ine zvakawanda zvakanaka, senge yakaderera simba rekushandisa, yakaderera mutengo, yakakwira chaiyo, yakatsetseka pamusoro uye yakanaka kudzokorora.Yakave ichishandiswa zvakanyanya muaerospace, mota, kugadzira mold, dhizaini yezvishongo, kurapwa uye mamwe minda.
Semuenzaniso, nekudhinda roketi injini prototype ine chimiro chakaomarara uye kuongorora mafambiro egasi, zvinobatsira kugadzira injini yeroketi ine compact dhizaini uye nepamusoro pesimba rinopisa, iro rinogona kunyatso kuvandudza R & D kushanda kwezvikamu zvakaoma uye. kupfupisa mota R & D kutenderera;Iwe unogona zvakare kudhinda iyo mold kana kudzosera mold zvakananga, kuitira kuti ugadzire mold nekukurumidza uye zvichingodaro.
Chiedza chekurapa 3D yekudhinda tekinoroji yakagadzira stereo lithography molding tekinoroji (SLA), dhijitari projekiti tekinoroji (DLP), 3D inkjet molding (3DP), inoenderera yemvura level kukura (clip) uye humwe matekinoroji [3].Sezvinyorwa zvayo zvekudhinda, photosensitive resin yechiedza kurapa 3D kudhinda yakafambira mberi zvikuru, uye iri kusimukira munzira yekushanda zvinoenderana nezvinodiwa zvekushandisa.
Electronic kurongedza UV kurapa zvigadzirwa
Iko kuvandudzwa kwetekinoroji yekurongedza inosimudzira shanduko yemidziyo yekurongedza kubva kusimbi kurongedza uye ceramic kurongedza kuenda kupurasitiki kurongedza.Epoxy resin inoshandiswa zvakanyanya mumapurasitiki ekurongedza.Yakanakisa mechanicha zvivakwa, kupisa uye hunyoro kuramba ndiyo misimboti yemhando yepamusoro yekurongedza.Dambudziko rakakosha kuona kushanda kwe epoxy resin harisi chete chimiro chemuviri mukuru we epoxy resin, asiwo pesvedzero yekurapa mumiririri.
Kuenzaniswa neiyo yekupisa yekurapa nzira inogamuchirwa neyakajairika epoxy resin, cationic UV kurapa haingove nekemikari yekuchengetedza yakagadzikana yephotoinitiator, asiwo kukurumidza kurapa kweiyo system inokurumidza.Kurapa kunogona kupedzwa mumakumi emasekonzi, nekunyanya kushanda zvakanaka, pasina oxygen polymerization inhibition uye kupora kwakadzika.Aya mabhenefiti anowedzera kuratidza kukosha kweiyo cationic UV yekurapa tekinoroji mumunda wemagetsi kurongedza.
Nekukurumidza kusimudzira kwesemiconductor tekinoroji, zvikamu zvemagetsi zvinowanzove zvakabatanidzwa zvakanyanya uye miniaturized.Huremu huremu, kusimba kwepamusoro, kunaka kwekudzivirira kupisa uye yakanakisa dielectric zvivakwa ichave maitiro ekuvandudza ezvinyowani zvepamusoro epoxy packaging zvinhu.Chiedza chekurapa tekinoroji ichaita basa rakakosha mukusimudzira indasitiri yekurongedza yemagetsi.
Ingi yekudhinda
Mumunda wekurongedza uye kudhinda, tekinoroji yekudhinda yeflexographic inoshandiswa zvakanyanya, ichiverengera chikamu chinowedzera.Yakave iyo tekinoroji yakakura yekudhinda uye kurongedza, uye ndiyo isingadzivisike maitiro ebudiriro mune ramangwana.
Kune marudzi akawanda einki eflexographic, kunyanya kusanganisira zvikamu zvinotevera: inks-based inki, solvent based inki uye ultraviolet curing (UV) ingi.Solvent based inki inonyanya kushandiswa pakudhinda firimu repurasitiki risingatore;Ingi yemvura inonyanya kushandiswa mumapepanhau, corrugated board, makadhibhokisi nezvimwe zvinhu zvinodhinda;UV inki inoshandiswa zvakanyanya, uye ine yakanaka kudhinda mhedzisiro mupurasitiki firimu, bepa, simbi foil uye zvimwe zvinhu [4].
Parizvino, UV yekudhinda inki inofarirwa zvakanyanya nemhando yayo yepamusoro uye kuchengetedzwa kwezvakatipoteredza, uye ine tarisiro yakanaka kwazvo yekusimudzira.
Flexographic UV inki inoshandiswa zvakanyanya mukurongedza kudhinda.Flexographic UV inki ine zvinotevera zvakanakira
(1) Flexographic UV inki haina solvent emission, yakachengeteka uye yakavimbika kushandiswa, yakakwira kunyungudika uye haina kusvibiswa, saka yakakodzera kugadzira chikafu, mushonga, chinwiwa uye kumwe kurongedza zvine zvakakwirira zvinodiwa zvekuchengetedza, zvisina chepfu yekurongedza zvinhu.
(2) Kana uchidhinda, zvinhu zvemuviri zveinki zvinoramba zvisina kuchinjwa, hapana chinonyungudutsa chinoputika, viscosity inoramba isingachinji, uye ndiro yekudhinda haizokuvadzwa, zvichiita kuti ndiro inonamatira, kusungirirwa kweplate uye zvimwe zviitiko.Paunenge uchidhinda neingi ine viscosity yakakwirira, kudhinda kuchiri kwakanaka.
(3) Iyo inki yekuomesa kumhanya inokurumidza uye kudhinda kwechigadzirwa kwakakwira.Inogona kushandiswa zvakanyanya mumhando dzakasiyana dzekudhinda, senge mapurasitiki, bepa, firimu uye mamwe ma substrates.
Nekuvandudzwa kweiyo oligomer dhizaini, inoshanda diluent uye initiator, ramangwana rekushandisa chiyero cheUV kurapa zvigadzirwa hachienzaniswe, uye nzvimbo yekuvandudza musika haina muganho.
