1. Iyini i-UV Curing Technology?
I-UV Curing Technology iwubuchwepheshe bokuphulukisa ngokushesha noma ukomisa ngemizuzwana lapho i-ultraviolet isetshenziswa ezinsikeni ezinjengama-coatings, ama-adhesives, inki yokumaka kanye ne-photo-resist, njll., ukuze kubangele i-photopolymerization. Ngezindlela zokusabela nge-olymerization ngokumisa ukushisa noma ukuxuba uketshezi olubili, ngokuvamile kuthatha phakathi kwemizuzwana embalwa ukuya emahoreni ambalwa ukomisa inhlaka.
Eminyakeni engaba ngu-40 edlule, lobu buchwepheshe baqala ukusetshenziswa ngokoqobo ekomisweni kokunyathelisa ku-plywood yezinto zokwakha. Kusukela ngaleso sikhathi, liye lasetshenziswa emikhakheni ethile.
Muva nje, ukusebenza kwe-UV resin elaphekayo kuye kwaba ngcono kakhulu. Ngaphezu kwalokho, izinhlobo ezahlukahlukene zama-resin elaphekayo e-UV seziyatholakala futhi ukusetshenziswa kwazo kanye nemakethe kukhula ngokushesha, ngoba kunenzuzo ngokonga amandla/indawo, ukwehlisa imfucuza, futhi kuzuzisa ukukhiqiza okuphezulu kanye nokwelashwa okunezinga lokushisa eliphansi.
Ngaphezu kwalokho, i-UV iphinde ilungele ukubumba i-optical ngoba inamandla amakhulu futhi ingagxila kumadayamitha amabala amancane, okusiza ukuthola kalula imikhiqizo ebunjwe ngokunemba okuphezulu.
Ngokuyisisekelo, ekubeni i-ejenti engancibiliki, inhlaka ye-UV eyelaphekayo ayiqukethe noma isiphi isincibilikisi esidala imiphumela emibi (isb, ukungcoliswa komoya) endaweni ezungezile. Ngaphezu kwalokho, njengoba amandla adingekayo ekwelapheni emancane futhi ukukhishwa kwe-carbon dioxide kuphansi, lobu buchwepheshe bunciphisa umthwalo wemvelo.
2. Izici Zokuphulukisa UV
1. Ukusabela kokwelapha kwenzeka ngemizuzwana
Ekuphenduleni kokwelapha, i-monomer (Uketshezi) ishintsha ibe yi-polymer (Okuqinile) phakathi kwamasekhondi ambalwa.
2. Ukusabela okuvelele kwezemvelo
Njengoba yonke into zelashwa ngokusetshenziswa kwe-photopolymerization engancibiliki, kusebenza kahle kakhulu ukufeza izimfuneko zemithethonqubo ehlobene nemvelo nama-oda afana ne-PRTR (Pollutant Release and Transfer Register) Law noma ISO 14000.
3. Iphelele ku-automation yenqubo
Izinto ezelaphekayo ze-UV aselapheki ngaphandle kokuthi zivezwe ekukhanyeni, futhi ngokungafani nezinto ezikwazi ukumelana nokushisa, azelapheki kancane kancane phakathi nokulondolozwa. Ngakho-ke, impilo yebhodwe layo yimfushane ngokwanele ukuthi isetshenziswe enqubweni ye-automation.
4. Ukwelashwa kwezinga lokushisa eliphansi kungenzeka
Njengoba isikhathi sokucubungula sisifushane, kungenzeka ukulawula ukukhuphuka kwezinga lokushisa lento ehlosiwe. Lesi esinye sezizathu zokuthi kungani sisetshenziswa kuma-electronics azwela ukushisa.
5. Ifanele yonke inhlobo yesicelo njengoba izinhlobonhlobo zezinto zitholakala
Lezi zinto zinobulukhuni obuphezulu obuphezulu kanye ne-gloss. Ngaphezu kwalokho, zitholakala ngemibala eminingi, ngakho-ke zingasetshenziselwa izinjongo ezihlukahlukene.
3. Isimiso se-UV Curing Technology
Inqubo yokushintsha i-monomer (uketshezi) ibe i-polymer (okuqinile) ngosizo lwe-UV ibizwa ngokuthi i-UV Curing E futhi okokwenziwa kwezinto eziphilayo okumele zelashwe kubizwa nge-UV Curable Resin E.
I-UV Curable Resin iyinhlanganisela equkethe:
(a) i-monomer, (b) i-oligomer, (c) i-photopolymerization initiator kanye (d) nezithasiselo ezihlukahlukene (izinza, izihlungi, izimibalabala, njll.).
(a) I-Monomer i-organic material eyenziwe i-polymerized futhi iguqulwa ibe ama-molecule amakhulu e-polymer ukuze yakhe ipulasitiki. (b) I-Oligomer yinto esevele yasabela kuma-monomers. Ngezindlela ezifanayo njenge-monomer, i-oligomer yenziwa i-polymerized futhi iguqulwa ibe ama-molecule amakhulu ukuze yakhe ipulasitiki. I-Monomer noma i-oligomer ayikhiqizi kalula ukusabela kwe-polymerization, ngakho-ke ihlanganiswa nesiqalisi se-photopolymerization ukuze kuqalwe ukusabela. (c) Isiqalisi se-photopolymerization siyajatshuliswa ukumuncwa ukukhanya nalapho ukusabela, okufana nokulandelayo, kwenzeka:
(b) (1) I-Cleavage, (2) Ukukhishwa kwe-Hydrogen, kanye (3) nokudluliselwa kwe-electron.
(c) Ngalokhu kusabela, izinto ezinjengama-radical molecule, ion hydrogen, njll., eziqala ukusabela ziyakhiqizwa. Ama-radical molecule akhiqiziwe, ama-hydrogen ions, njll., ahlasela ama-oligomer noma ama-monomer molecule, kanye ne-polymerization enezinhlangothi ezintathu noma ukuphambana kwe-crosslinking kwenzeka. Ngenxa yalokhu kusabela, uma ama-molecule anosayizi omkhulu kunosayizi oshiwo akhiwa, ama-molecule avezwe ku-UV ashintsha ukusuka oketshezini kuya kokuqinile. (d) Izithasiselo ezahlukahlukene (i-stabilizer, filler, pigment, njll.) zengezwa ekwakhiweni kweresin elaphekayo ye-UV njengoba kudingekile, ukuze
(d) inikeze ukuzinza, amandla, njll.
(e) I-resin yesimo esiwuketshezi ye-UV eyelaphekayo, egeleza ngokukhululeka, ivamise ukuphulukiswa yizinyathelo ezilandelayo:
(f) (1) Iziqalisi ze-Photopolymerization zimunca i-UV.
(g) (2) Lezi ziqalisi ze-photopolymerization ezimunce i-UV zijabule.
(h) (3) Iziqalisi ze-photopolymerization ezicushiwe zisabela ngezingxenye ze-resin njenge-oligomer, i-monomer, njll., ngokubola.
(i) (4) Ngaphezu kwalokho, le mikhiqizo isabela ngezingxenye ze-resin kanye nokusabela kweketango. Khona-ke, ukusabela kwe-crosslinking ye-three-dimensional kuyaqhubeka, isisindo samangqamuzana siyanda futhi i-resin iyaphulukiswa.
(j) 4. Yini i-UV?
(k) I-UV iyigagasi kazibuthe lika-100 kuya ku-380nm ubude begagasi, lide kunalelo lama-X ray kodwa lifushane kunalelo lemisebe ebonakalayo.
(l) I-UV ihlukaniswe yaba izigaba ezintathu eziboniswe ngezansi ngokobude bayo begagasi:
(m) UV-A (315-380nm)
(n) UV-B (280-315nm)
(o) UV-C (100-280nm)
(p) Uma i-UV isetshenziselwa ukwelapha inhlaka, amayunithi alandelayo asetshenziswa ukukala inani lemisebe ye-UV:
(q) - Amandla okukhipha imisebe (mW/cm2)
(r) Amandla okukhipha imisebe endaweni ngayinye
(s) - Ukuchayeka kwe-UV (mJ/ cm2)
(t) Amandla okukhipha imisebe endaweni yeyunithi ngayinye kanye nenani eliphelele lamaphothoni ukuze afinyelele phezulu. Umkhiqizo wokuqina kwe-irradiation nesikhathi.
(u) - Ubudlelwano phakathi kokuchayeka kwe-UV namandla okukhipha imisebe
(v) E=I x T
(w) E=Ukukhanya kwe-UV (mJ/cm2)
(x) I =Ukuqina (mW/cm2)
(y) T=Isikhathi sokushiswa kwemisebe (s)
(z) Njengoba ukuchayeka kwe-UV okudingekile ekwelapheni kuncike ezintweni, isikhathi esidingekayo sokushiswa kwemisebe singatholwa ngokusebenzisa ifomula engenhla uma uwazi amandla emisebe ye-UV.
(aa) 5. Isingeniso Somkhiqizo
(ab) Isisetshenziswa esisebenzayo sohlobo lwe-UV
(ac) Isisetshenziswa Sokwelapha Sohlobo Oluphathwayo siyintengo encane kakhulu nesiphansi kunazo zonke Isisetshenziswa Sokwelapha Se-UV phakathi kohlu lomkhiqizo wethu.
(ad) Izisetshenziswa Ezakhelwe ngaphakathi Zokulapha UV
(ae) Izisetshenziswa Ezakhelwe ngaphakathi Zokulapha i-UV zinikezwa ubuncane bomshini odingekayo wokusebenzisa isibani se-UV, futhi zingaxhunywa kuzinto ezisetshenziswayo ezinomshini wokuthutha.
Lo mshini wakhiwe ngesibani, i-irradiator, umthombo wamandla kanye nethuluzi lokupholisa. Izingxenye ozikhethela zingafakwa ku-irradiator. Izinhlobo ezahlukene zemithombo yamandla kusuka ku-inverter elula kuya kuma-inverters ezinhlobo eziningi ziyatholakala.
Isisetshenziswa Sokwelapha Se-UV sedeskithophu
Lesi Isisetshenziswa Sokwelapha Se-UV esiklanyelwe ukusetshenziswa kwedeskithophu. Njengoba ihlangene, idinga isikhala esincane sokufakwa futhi iyonga kakhulu. Ifaneleka kakhulu izivivinyo nokuhlolwa.
Lo mshini unomshini wokuvala owakhelwe ngaphakathi. Noma isiphi isikhathi esifiswayo sokushiswa kwemisebe singasethwa ukuze kusetshenziswe imisebe ephumelela kakhulu.
Isisetshenziswa Sokuphulukisa se-UV sohlobo lwe-Conveyor
Imishini Yokwelapha ye-UV yohlobo lwe-Conveyor inikezwa ngamaconveyor ahlukahlukene.
Siklama futhi sakha uhla olubanzi lwemishini kusukela ku-compact UV Curing Equipment enezidluliseli ezihlangene kuya ezintweni ezinosayizi omkhulu ezinezindlela zokudlulisa ezihlukene, futhi sihlala sinikela ngezinto ezifanele izidingo zamakhasimende.
