1. Yintoni iTekhnoloji yoNyango lwe-UV?
Itekhnoloji yoNyango lwe-UV yitekhnoloji yokunyanga okanye ukomisa kwangoko ngemizuzwana apho i-ultraviolet ifakwa kwi-resin ezinje ngeengubo, ukuncamathelisa, ukuphawula i-inki kunye ne-photo-resissive, njl., ukubangela i-photopolymerization. Ngeendlela zokuphendula i-olymerization ngokumisa ubushushu okanye ukuxuba ulwelo ezimbini, ngokuqhelekileyo kuthatha phakathi kwemizuzwana embalwa ukuya kwiiyure ezininzi ukomisa iresin.
Malunga neminyaka engama-40 eyadlulayo, obu buchwephesha baqala ukusetyenziswa ngokoqobo ukomisa ushicilelo lweplywood kwizixhobo zokwakha. Ukususela ngoko, iye yasetyenziswa kwiinkalo ezithile.
Kutshanje, ukusebenza kwe-resin enyangekayo ye-UV kuphuculwe kakhulu. Ngaphaya koko, iindidi ngeendidi zeeresina ezinyangekayo ze-UV ngoku ziyafumaneka kwaye ukusetyenziswa kwazo kunye nentengiso ikhula ngokukhawuleza, kuba inenzuzo malunga nokonga amandla / indawo, ukunciphisa inkunkuma, kwaye ifezekisa imveliso ephezulu kunye nonyango olunobushushu obuphantsi.
Ukongeza, i-UV ikwalungele ukubumba i-optical kuba inoxinzelelo oluphezulu lwamandla kwaye inokugxila kubuncinci bedayamitha zamabala, enceda ukufumana ngokulula iimveliso ezibunjiweyo ezichanekileyo.
Ngokusisiseko, ekubeni yiarhente enganyibilikiyo, i-resin enyangekayo ye-UV ayinaso nasiphi na isinyibilikisi sendalo esibangela iziphumo ezibi (umzekelo, ungcoliseko lomoya) kokusingqongileyo. Ngaphezu koko, ekubeni amandla afunekayo ekunyangeni engaphantsi kwaye ukukhutshwa kwekharbon diokside kuphantsi, obu bugcisa bunciphisa umthwalo wokusingqongileyo.
2. Iimpawu zokuNyangwa kwe-UV
1. Ukunyanga ukusabela kwenzeka ngemizuzwana
Kwimpendulo yonyango, i-monomer (Ulwelo) itshintsha ibe yipolymer (Eqinile) kwimizuzwana embalwa.
2. Ukusabela okubalaseleyo kokusingqongileyo
Ekubeni yonke into ngokusisiseko iphiliswa yi-photopolymerization ye-solvent-free, iyasebenza kakhulu ukuzalisekisa iimfuno zemimiselo enxulumene nokusingqongileyo kunye nemiyalelo efana ne-PRTR (i-Pollutant Release and Transfer Register) uMthetho okanye i-ISO 14000.
3. Igqibelele kwinkqubo yokuzenzekelayo
Izinto ezinyangekayo ze-UV azinyangeki ngaphandle kokuba zibekwe ekukhanyeni, kwaye ngokungafaniyo nezixhobo ezinyangekayo bubushushu, azinyangeki ngokuthe ngcembe ngexesha lokulondolozwa. Ke ngoko, imbiza-ubomi bayo bufutshane ngokwaneleyo ukuba isetyenziswe kwinkqubo yokuzenzela.
4. Unyango oluphantsi lobushushu lunokwenzeka
Ekubeni ixesha lokucubungula lifutshane, kunokwenzeka ukulawula ukunyuka kobushushu bento ekujoliswe kuyo. Esi sesinye sezizathu zokuba isetyenziswe kwii-elektroniki ezininzi ezingevani nobushushu.
5. Ifanelekile kulo lonke uhlobo lwesicelo ukususela kwizinto ezahlukeneyo ezikhoyo
Ezi zixhobo zinobulukhuni obuphezulu kunye neglosi. Ngaphezu koko, zifumaneka ngemibala emininzi, kwaye ngenxa yoko zinokusetyenziselwa iinjongo ezahlukeneyo.
3. Umgaqo-siseko weTekhnoloji yoNyango lwe-UV
Inkqubo yokutshintsha i-monomer (ulwelo) ibe yipolymer (eqinile) ngoncedo lwe-UV ibizwa ngokuba yi-UV Curing E kunye ne-synthetic organic material eza kunyangwa ibizwa ngokuba yi-UV Curable Resin E.
I-UV Curable Resin yikhompawundi equka:
(a) i-monomer, (b) i-oligomer, (c) i-photopolymerization initiator kunye (d) izongezo ezahlukeneyo (izinzinzi, izihluzi, ii-pigments, njl. njl.).
(a) I-Monomer yimathiriyeli ephilayo eyenziwe ipolymer kwaye iguqulwa ibe ziimolekyuli ezinkulu zepolymer ukwenza iplastiki. (b) I-Oligomer yinto esele isabela kwiimonomers. Ngeendlela ezifanayo njenge-monomer, i-oligomer i-polymerized kwaye iguqulwa ibe yi-molecule ezinkulu ukwenza iplastiki. I-Monomer okanye i-oligomer ayivelisi ngokulula i-polymerization reaction, ngenxa yoko zidityaniswa ne-photopolymerization initiator ukuqala ukusabela. (c) Umqalisi we-photopolymerization uyachulumanca kukufakwa kokukhanya kwaye xa iimpendulo, ezinje zilandelayo, zenzeka:
(b) (1) Ukucoca, (2) Ukutsalwa kweHydrogen, kunye (3) nokuhanjiswa kwe-Electron.
(c) Ngale ndlela yokusabela, izinto ezinjengeemolekyuli ezinkulu, ii-ion zehydrogen, njl.njl., eziqalisa ukusabela ziyenziwa. Iimolekyuli ze-radical ezenziweyo, i-hydrogen ions, njl., i-oligomer okanye i-monomer molecules ezihlaselayo, kunye ne-polymerization ye-dimensional-dimensional okanye i-crosslinking reaction iyenzeka. Ngenxa yolu tshintsho, ukuba iimolekyuli ezinobungakanani obukhulu kunobukhulu obuchaziweyo zenziwe, iimolekyuli ezivezwe kwi-UV zitshintsha ukusuka kulwelo ukuya kokuqinileyo. (d) Izongezo ezohlukeneyo (i-stabilizer, filler, pigment, njl. njl.) zongezwa kwi-UV enyangekayo yeresin edityanisiweyo njengoko kufuneka, ukuze
(d) inike uzinzo, amandla, njl.
(e) I-resin enyangekayo ye-UV ekwimeko yolwelo, ehamba ngokukhululekileyo, idla ngokunyangwa ngala manyathelo alandelayo:
(f) (1) Abaqalisi befotopolymerization bafunxa i-UV.
(g) (2) Ezi ziqalisi ze-photopolymerization ezifunxa i-UV ziyavuya.
(h) (3) Abaqalisi be-photopolymerization basebenze kunye namacandelo e-resin afana ne-oligomer, i-monomer, njl., ngokubola.
(i) (4) Ngaphezu koko, ezi mveliso zisabela kunye namacandelo e-resin kunye ne-chain reaction reaction. Emva koko, i-reaction-dimensional crosslinking reaction iyaqhubeka, ubunzima bemolekyuli buyanda kwaye i-resin iyaphiliswa.
(j) 4. Yintoni iUV?
k
(l) I-UV ihlelwe ngokweendidi ezintathu eziboniswe ngezantsi ngokobude bayo:
(m) UV-A (315-380nm)
(n) UV-B (280-315nm)
(o) UV-C (100-280nm)
(p) Xa i-UV isetyenziselwa ukunyanga intlaka, ezi yunithi zilandelayo zisetyenziselwa ukulinganisa ubungakanani bemitha ye-UV:
(q) - Ubunzulu bokukhanya (mW/cm2)
(r) Ubunzulu bomitha ngokweyunithi yendawo nganye
(s) - Uvelelo lweUV (mJ/ cm2)
(t) Amandla ombane kwiyunithi yendawo nganye kunye nobungakanani obupheleleyo beefotoni ukufikelela kumphezulu. Imveliso ye-irradiation intensity kunye nexesha.
(u) - Ubudlelwane phakathi kokuvezwa kwe-UV kunye nobunzulu bomitha
(v) E=Mna x T
(w) E=Ukukhanya kweUV (mJ/cm2)
(x) I =Ubukhulu (mW/cm2)
(y) T=Ixesha lokukhanya (s)
(z) Ekubeni i-UV exposure efunekayo yokunyanga ixhomekeke kwizinto eziphathekayo, ixesha elifunekayo le-irradiation lingafumaneka ngokusebenzisa le fomula ingentla ukuba uyazi ukuba i-UV irradiation intensity.
