1. Yintoni iTekhnoloji yokuPhilisa i-UV?
I-UV Curing Technology yiteknoloji yokunyanga okanye ukomisa ngokukhawuleza ngemizuzwana apho i-ultraviolet ifakwa kwiiresini ezifana neengubo, izincamathelisi, i-inki yokumakisha kunye ne-photo-resists, njl.njl., ukuze kubangele i-photopolymerization. Ngeendlela zokusabela nge-olymerization ngokumisa ngobushushu okanye ngokuxuba ulwelo olubini, kudla ngokuthatha imizuzwana embalwa ukuya kwiiyure ezininzi ukomisa iresini.
Kwiminyaka engama-40 eyadlulayo, obu buchwephesha baqala ukusetyenziswa ngokoqobo ekomiseni ushicilelo kwi-plywood ukuze kwenziwe izinto zokwakha. Ukususela ngoko, busetyenziswa kwiindawo ezithile.
Kutshanje, ukusebenza kwe-resin enyangekayo ye-UV kuphucuke kakhulu. Ngaphezu koko, iintlobo ezahlukeneyo ze-resin enyangekayo ye-UV ngoku ziyafumaneka kwaye ukusetyenziswa kwazo kunye nemarike kukhula ngokukhawuleza, kuba kuluncedo ngokubhekiselele ekongeni amandla/indawo, ukunciphisa inkunkuma, kwaye kufezekisa imveliso ephezulu kunye nonyango oluphantsi kobushushu.
Ukongeza, i-UV ikwafanelekile ekubumbeni okubonakalayo kuba inamandla aphezulu kwaye inokugxila kwiidayamitha ezincinci, nto leyo enceda ekufumaneni ngokulula iimveliso ezibunjiweyo ezichanekileyo.
Ngokusisiseko, ekubeni i-resin enganyangekiyo, i-UV resin ayinaso nasiphi na isinyibilikisi sendalo esibangela iziphumo ezimbi (umz., ungcoliseko lomoya) kwindalo esingqongileyo. Ngaphezu koko, ekubeni amandla afunekayo ukuze kulungiswe inkunkuma emancinci kwaye ukukhutshwa kwekhabhoni diokside kuphantsi, le ndlela yobuchwephesha iyawunciphisa umthwalo kwindalo esingqongileyo.
2. Iimpawu zoNyango lwe-UV
1. Impendulo yokuphilisa yenzeka ngemizuzwana
Kwi-curing reaction, i-monomer (Liquid) itshintsha ibe yi-polymer (Solid) kwimizuzwana embalwa.
2. Ukusabela okubalaseleyo kwindalo esingqongileyo
Ekubeni yonke into inyangwa yi-photopolymerization engenasombululo, iyasebenza kakhulu ukufezekisa iimfuno zemigaqo kunye nemiyalelo enxulumene nokusingqongileyo efana noMthetho we-PRTR (Ukukhululwa kobumdaka kunye neRejista yoTshintsho) okanye i-ISO 14000.
3. Ifanelekile kwi-automation yenkqubo
Izinto ezinyangekayo nge-UV azinyangeki ngaphandle kokuba zibekwe ekukhanyeni, kwaye ngokungafaniyo nezinto ezinyangekayo ngobushushu, azinyangeki kancinci ngexesha lokugcinwa. Ngenxa yoko, ubomi bazo obufutshane ngokwaneleyo ukuba zisetyenziswe kwinkqubo yokuzisebenzela.
4. Unyango oluphantsi lobushushu lunokwenzeka
Ekubeni ixesha lokucubungula lifutshane, kunokwenzeka ukulawula ukunyuka kobushushu bento ekujoliswe kuyo. Esi sesinye sezizathu zokuba isetyenziswa kwii-elektroniki ezininzi ezibuthathaka kubushushu.
5. Ifanelekile kuzo zonke iintlobo zesicelo kuba kukho izinto ezahlukeneyo ezifumanekayo
Ezi zinto zinobulukhuni obuphezulu kunye nokukhazimla. Ngaphezu koko, zifumaneka ngemibala emininzi, ngoko ke zinokusetyenziselwa iinjongo ezahlukeneyo.
3. Umgaqo weTekhnoloji yokuPhilisa i-UV
Inkqubo yokutshintsha i-monomer (ulwelo) ibe yi-polymer (eqinileyo) ngoncedo lwe-UV ibizwa ngokuba yi-UV Curing E kwaye izinto eziphilayo ezidityanisiweyo eziza kunyangwa zibizwa ngokuba yi-UV Curable Resin E.
I-UV Curable Resin yikhompawundi equlathe oku kulandelayo:
(a) i-monomer, (b) i-oligomer, (c) i-photopolymerization initiator kunye (d) nezinye izongezo ezahlukeneyo (izinzisi, izizalisi, iipigment, njl.njl.).
(a) I-Monomer yinto ephilayo epholishwayo ize iguqulwe ibe ziimolekyuli ezinkulu ze-polymer ukuze zenze iplastiki. (b) I-Oligomer yinto esele isabela kwiimonomers. Ngendlela efanayo ne-monomer, i-oligomer ipholishwayo ize iguqulwe ibe ziimolekyuli ezinkulu ukuze zenze iplastiki. I-Monomer okanye i-oligomer azivelisi lula i-polymerization reaction, ngoko ke zidityaniswe ne-photopolymerization initiator ukuze kuqalwe i-reaction. (c) I-photopolymerization initiator iyavuya kukufunxwa kokukhanya kwaye xa kwenzeka ii-reaction, ezifana nezi zilandelayo:
(b) (1) Ukuqhekeka, (2) Ukutsalwa kweHydrogen, kunye (3) nokudluliselwa kwe-electron.
(c) Ngale ndlela yokusabela, izinto ezifana nee-radical molecules, ii-hydrogen ions, njl.njl., eziqala le ndlela yokusabela ziyaveliswa. Ii-radical molecules eziveliswayo, ii-hydrogen ions, njl.njl., zihlasela ii-oligomer okanye ii-monomer molecules, kunye ne-polymerization okanye i-crosslinking reaction eyenzekayo. Ngenxa yale ndlela yokusabela, ukuba ii-molecules ezinobukhulu obukhulu kunobungakanani obuchaziweyo ziyakhiwa, ii-molecules ezivezwa kwi-UV ziyatshintsha ukusuka kulwelo ukuya kwi-solid. (d) Izongezo ezahlukeneyo (isizinzisi, isizalisi, i-pigment, njl.njl.) zongezwa kwi-UV treatable resin composition njengoko kufuneka, ukuze
(d) ukunika uzinzo, amandla, njl.njl.
(e) I-resin ye-UV enyangekayo ekwimeko yolwelo, ekwaziyo ukugeleza ngokukhululekileyo, idla ngokunyangwa ngala manyathelo alandelayo:
(f) (1) Abaqalisi be-photopolymerization bafunxa i-UV.
(g) (2) Aba baqalisi be-photopolymerization abafunxe i-UV bayavuya.
(h) (3) Abaqalisi be-photopolymerization abasebenza ngokusebenza basabela kunye nezinto ze-resin ezifana ne-oligomer, i-monomer, njl.njl., ngokubola.
(i) (4) Ngaphezu koko, ezi mveliso zisabela kunye nezinto ze-resin kwaye kuqhubeka ukusabela kwetsheyini. Emva koko, ukusabela kwe-three-dimensional crosslinking kuyaqhubeka, ubunzima be-molecular buyanda kwaye i-resin iyaphiliswa.
(j) 4. Yintoni i-UV?
(k) I-UV ligagasi le-electromagnetic elinobude obuyi-100 ukuya kwi-380nm, elide kunele-X-rays kodwa lifutshane kunele-reyi ebonakalayo.
(l) I-UV yahlulwe yangamacandelo amathathu aboniswe ngezantsi ngokwe-wavelength yayo:
(m) UV-A (315-380nm)
(n) UV-B (280-315nm)
(o) I-UV-C (100-280nm)
(p) Xa i-UV isetyenziselwa ukunyanga i-resin, ezi yunithi zilandelayo zisetyenziselwa ukulinganisa ubungakanani bemitha ye-UV:
(q) - Ubungakanani bokukhanya (mW/cm2)
(r) Ubungakanani bokukhanya kwendawo nganye
(s) - Ukuvezwa kwe-UV (mJ/ cm2)
(t) Amandla okukhanyisela ngeyunithi nganye kunye nobungakanani obupheleleyo beefotoni ukufikelela kumphezulu. Imveliso yobukhali bemitha kunye nexesha.
(u) - Ubudlelwane phakathi kokuvezwa yi-UV kunye nokuqina kwemitha
(v) E=I x T
(w) Ukuvezwa kwe-E=UV (mJ/cm2)
(x) I = Ubungakanani (mW/cm2)
(y) T=Ixesha lokuKhanya
(z) Ekubeni ukuvezwa kwe-UV okufunekayo ukuze kukhanye kuxhomekeke kwizinto ezisetyenzisiweyo, ixesha lokukhanya elifunekayo lingafunyanwa ngokusebenzisa le fomyula ingasentla ukuba uyazi amandla okukhanya kwe-UV.
