Tekinoroji yekurapa UV

1. Chii chinonzi UV Curing Technology?

UV Curing Technology itekinoroji yekupisa kana kuomesa nekukurumidza mumasekonzi umo ultraviolet inoiswa pamaresini akadai sekuputira, zvinonamira, inki yekuisa chiratidzo uye zvinodzivirira kusvibiswa kwemvura, nezvimwewo, kuti zvikonzere kusvibiswa kwemvura. Nenzira dzekuita olymerization nekupisa kana kusanganisa mvura mbiri, zvinowanzotora masekondi mashoma kusvika maawa akati wandei kuti resin iome.

Makore angangoita makumi mana apfuura, tekinoroji iyi yakatanga kushandiswa pakuomesa kudhinda paplywood kuti ishandiswe pakuvaka. Kubva ipapo, yave ichishandiswa muminda chaiyo.

Munguva pfupi yapfuura, mashandiro eresin inorapika yeUV akawedzera zvakanyanya. Uyezve, mhando dzakasiyana dzeresin dzinorapika dzeUV dzava kuwanikwa uye kushandiswa kwadzo pamwe nemusika zviri kukura nekukurumidza, sezvo zvichibatsira pakuchengetedza simba/nzvimbo, kuderedza marara, uye zvichiita kuti pave nekubudirira kwakanyanya uye kurapwa pakupisa kushoma.

Pamusoro pezvo, UV yakakodzerawo kugadzira optical molding sezvo ine simba rakawanda uye inogona kutarisa pa diki spot diameters, izvo zvinobatsira kuwana zviri nyore zvigadzirwa zvakagadzirwa nemazvo.

Chaizvoizvo, sezvo iri resin isinganyungudike, resin inorapika yeUV haina organic solvent inokonzera migumisiro yakaipa (semuenzaniso, kusvibiswa kwemhepo) pane zvakatipoteredza. Uyezve, sezvo simba rinodiwa pakupisa riri shoma uye kuburitswa kwecarbon dioxide kwakaderera, tekinoroji iyi inoderedza mutoro wezvakatipoteredza.

2. Zvinhu Zvinoshandiswa pakurapa UV

1. Kuporeswa kwemuviri kunoitika mumasekonzi mashoma

Mukuita kwekupisa, monomer (Liquid) inoshanduka kuita polymer (Solid) mukati memasekonzi mashoma.

2. Kushanda zvakanaka kwezvakatipoteredza

Sezvo zvinhu zvese zvichinyatsogadziriswa ne photopolymerization isina solvent, zvinoshanda zvikuru kuzadzisa zvinodiwa nemitemo nemirairo ine chekuita nezvakatipoteredza zvakaita sePRTR (Pollutant Release and Transfer Register) Law kana ISO 14000.

3. Yakakwana pakuita otomatiki kwemaitiro

Zvinhu zvinorapika neUV hazvirapiki kana zvikasaiswa muchiedza, uye kusiyana nezvinhu zvinorapika nekupisa, hazvirapiki zvishoma nezvishoma panguva yekuchengetedzwa. Saka, nguva yazvo yekubuda muhari ipfupi zvakakwana kuti ishandiswe mukuita otomatiki.

4. Kurapa nekupisa kwakaderera kunogoneka

Sezvo nguva yekugadzirisa iri pfupi, zvinokwanisika kudzora kukwira kwekupisa kwechinhu chaunoda. Ichi ndicho chimwe chezvikonzero nei chichishandiswa mumagetsi mazhinji anonyanya kupisa.

5. Yakakodzera mhando dzese dzekushandisa sezvo zvinhu zvakasiyana-siyana zviripo

Zvinhu izvi zvine kuomarara kwepamusoro uye zvinopenya zvakanyanya. Uyezve, zvinowanikwa mumavara akasiyana-siyana, saka zvinogona kushandiswa pazvinangwa zvakasiyana-siyana.

3. Nheyo yeTekinoroji yeKurapa UV

Maitiro ekushandura monomer (mvura) kuita polymer (yakasimba) nerubatsiro rweUV anonzi UV Curing E uye zvinhu zvakasikwa zvekugadzira zvinoda kurapwa zvinonzi UV Curable Resin E

Resin inorapika yeUV isanganiswa ine:

(a) monomer, (b) oligomer, (c) photopolymerization initiator uye (d) zvimwe zvinhu zvakasiyana-siyana (zvinosimbisa, zvinozadza, pigments, nezvimwewo).

(a) Monomer chinhu cheorganic chinogadziriswa polymer uye chinoshandurwa kuita mamorekuru makuru epolymer kuti chigadzire purasitiki. (b) Oligomer chinhu chakatoita reactive kune monomers. Nenzira imwecheteyo semonomer, oligomer inogadziriswa polymer uye inoshandurwa kuita mamorekuru makuru kuti igadzire purasitiki. Monomer kana oligomer hazvibudisi nyore polymerization reaction, saka zvinosanganiswa ne photopolymerization initiator kuti zvitange reaction. (c) Photopolymerization initiator inofara nekutorwa kwechiedza uye kana reactions, dzakadai sedzinotevera, dzichiitika:

(b) (1) Kuchekwa, (2) Kubviswa kwehydrogen, uye (3) Kutamiswa kwemaerekitironi.

(c) Nekuita uku, zvinhu zvakaita sema radical molecules, hydrogen ions, nezvimwewo, zvinotanga kuita uku zvinogadzirwa. Ma radical molecules, hydrogen ions, nezvimwewo, anorwisa oligomer kana monomer molecules, uye three-dimensional polymerization kana crosslinking reaction inoitika. Nekuda kwekuita uku, kana mamorekuru ane saizi yakakura kupfuura saizi yakatarwa akaumbwa, mamorekuru anoonekwa kuUV anochinja kubva mumvura kuenda kune solid. (d) Zvimwe zvinhu zvakasiyana-siyana (stabilizer, filler, pigment, nezvimwewo) zvinowedzerwa kuUV therapyable resin composition sezvinodiwa, kuti

(d) kuipa kugadzikana, simba, nezvimwewo.

(e) Resin inorapika yeUV inorapika ine mvura, iyo inoyerera zvakanaka, inowanzo gadziriswa nematanho anotevera:

(f) (1) Zvishandiso zve Photopolymerization zvinonwisa UV.

(g) (2) Izvi zvinotanga kugadzirwa kwephotopolymerization zvakatora UV zvinofara.

(h) (3) Zvishandiso zve photopolymerization zvinoitwa ne resin zvakaita se oligomer, monomer, nezvimwewo, kuburikidza nekuora.

(i) (4) Uyezve, zvigadzirwa izvi zvinosangana nezvikamu zve resin uye chain reaction inoenderera mberi. Zvadaro, three-dimensional crosslinking reaction inoenderera mberi, molecular weight inowedzera uye resin inoporeswa.

(j) 4. Chii chinonzi UV?

(k) UV iwaya remagetsi rine urefu hwemarefu hwe100 kusvika 380nm, rakareba kupfuura remaX-ray asi rakapfupika pane remwaranzi inoonekwa.

(l) UV yakakamurwa kuita zvikamu zvitatu zviri pazasi zvichienderana nehurefu hwemhepo hwayo:

(m) UV-A (315-380nm)

(n) UV-B (280-315nm)

(o) UV-C (100-280nm)

(p) Kana UV ichishandiswa kurapa resin, mayuniti anotevera anoshandiswa kuyera huwandu hwemwaranzi yeUV:

(q) - Kuwanda kwemwaranzi (mW/cm2)

(r) Kuwanda kwemwaranzi panzvimbo imwe neimwe

(s) - Kuratidzwa kweUV (mJ/ cm2)

(t) Simba rekuvhenekesa pachikamu chimwe nechimwe uye huwandu hwese hwemaphotoni kusvika pamusoro. Chibereko chekupenya kwenguva nenguva.

(u) - Hukama huripo pakati pekuratidzwa kweUV nekusimba kwemwaranzi

(v) E=I x T

(w) E=Kuonekwa kweUV (mJ/cm2)

(x) I = Kusimba (mW/cm2)

(y) T=Nguva yekuvhenekesa (s)

(z) Sezvo kuratidzwa kweUV kunodiwa pakupisa kunoenderana nezvinhu, nguva inodiwa yekuvhenekesa inogona kuwanikwa nekushandisa fomura iri pamusoro apa kana uchiziva simba rekuvhenekesa UV.

(aa) 5. Nhanganyaya yeChigadzirwa

(ab) Midziyo yekurapa UV inoshanda zvakanaka

(ac) Midziyo yekurapa yemhando yepamusoro ndiyo michina yekurapa yeUV iri pamutengo wakaderera uye iri pakati pezvigadzirwa zvedu.

(ad) Midziyo yekurapa UV yakavakirwa mukati

(ae) Midziyo yeUV inogadziriswa mukati ine nzira shoma inodiwa yekushandisa rambi reUV, uye inogona kubatanidzwa kumidziyo ine conveyor.

Midziyo iyi inoumbwa nerambi, irradiator, sosi yemagetsi uye mudziyo wekutonhodza. Zvimwe zvikamu zvinogona kubatanidzwa pairradiator. Mhando dzakasiyana dzemagetsi kubva painverter iri nyore kusvika kune mainverter emhando dzakasiyana-siyana dziripo.

Midziyo yekurapa yeUV yeDesktop

Iyi UV Curing Equipment yakagadzirirwa kushandiswa pakombiyuta. Sezvo iri diki, haidi nzvimbo yakawanda yekuiisa uye inodhura zvishoma. Yakanyanya kukodzera kuyedzwa uye kuyedzwa.

Mudziyo uyu une nzira yekuvhara yakavakirwa mukati. Nguva yemwaranzi inodiwa inogona kugadzirirwa kuti imwaranzi ishande zvakanaka.

Midziyo yekurapa UV yerudzi rweConveyor

Midziyo yekurapa UV yerudzi rweConveyor inopihwa nema conveyor akasiyana-siyana.

Tinogadzira nekugadzira michina yakasiyana-siyana kubva kuCompact UV Curing Equipment ine macompact conveyors kusvika kumidziyo mikuru ine nzira dzakasiyana dzekutumira, uye tinogara tichipa michina inoenderana nezvinodiwa nevatengi.
