Yintoni iglu ye-UV?
Igama elithi "UV glue" libhekisa kwiglu engenamthunzi, eyaziwa ngokuba yi-photosensitive okanye i-ultraviolet treatment adhesive. Iglue ye-UV ifuna ukunyibilika ngokukhanya kwe-ultraviolet kwaye ingasetyenziselwa ukubopha, ukupeyinta, ukugquma, kunye nezinye iindlela zokusebenza. Isifinyezo esithi "UV" simele ii-Ultraviolet Rays, eziyi-electromagnetic radiation engabonakaliyo ene-wavelengths ukusuka kwi-110 ukuya kwi-400nm. Umgaqo osemva kokunyibilika kwe-UV glue engenamthunzi ubandakanya ukufunxwa kokukhanya kwe-ultraviolet yi-photoinitiators okanye ii-photosensitizers kwisixhobo, okukhokelela ekudalweni kwee-free radicals ezisebenzayo okanye ii-cations eziqala i-polymerization kunye nee-cross-linking reactions kwimizuzwana embalwa.
Inkqubo yokuncamathelisa iglue engenamthunzi: iglue engenamthunzi ikwabizwa ngokuba yiglue ye-ultraviolet, kufuneka idlule kwi-ultraviolet i-radiation ukuya kwiglue phantsi kwesiseko sokuphilisa, oko kukuthi, i-photosensitizer kwiglue engenamthunzi kwaye ukudibana nokukhanya kwe-ultraviolet kuya kudibana ne-monomer, ngokwethiyori ngaphandle kokukhanyiselwa komthombo wokukhanya kwe-ultraviolet iglue engenamthunzi ayisoze iphiliswe. Okukhona isantya sokuphilisa se-UV siqina, kokukhona ixesha lokuphilisa ngokubanzi liqala kwimizuzwana eli-10-60. Iglue engenamthunzi kufuneka ikhanyiswe kukukhanya ukuze iphiliswe, ngoko iglue engenamthunzi esetyenziselwa ukubopha ngokubanzi inokudityaniswa nezinto ezimbini ezibonakalayo okanye enye yazo kufuneka ibonakale, ukuze ukukhanya kwe-ultraviolet kudlule kwaye kukhanye kwiglu.
Iimpawu zeglue ye-UV
1. Ukhuseleko/ukhuseleko lokusingqongileyo
Akukho zi-VOC volatiles, akukho ungcoliseko lomoya ongqongileyo; izithako ezincamathelayo azithintelwanga kakhulu okanye azivumelekanga kwimigaqo yokusingqongileyo; akukho nyibilikisi, kwaye akukho kutsha kakhulu
2. Kulula ukuyisebenzisa kwaye iphucula ukusebenza kakuhle kwemveliso
Isantya sokulungisa sikhawuleza kwaye singagqitywa kwimizuzwana embalwa ukuya kwishumi lemizuzwana, nto leyo eluncedo kwimigca yemveliso ezenzekelayo kwaye iphucula imveliso yabasebenzi. Emva kokulungisa, ingahlolwa kwaye ithuthwe, okonga indawo. Ukulungisa kubushushu begumbi konga amandla, njengokuveliswa kwe-1g ye-glue ethintela uxinzelelo ekukhanyeni. Amandla afunekayo yi-1% kuphela ye-glue esekwe emanzini ehambelanayo kunye ne-4% ye-glue esekwe kwi-solvent. Ingasetyenziselwa izinto ezingafanelekanga ukucoca kubushushu obuphezulu. Amandla asetyenziswa yi-ultraviolet curing anokonga i-90% xa kuthelekiswa ne-thermal curing resin. Izixhobo zokulungisa zilula kwaye zifuna kuphela izibane okanye iibhanti zokuhambisa. Ukonga indawo; inkqubo yecandelo elinye, akukho mfuneko yokuxuba, kulula ukuyisebenzisa.
3. Ukuhambelana
Izinto ezinobuthathaka kubushushu, izinyibilikisi kunye nokufuma zingasetyenziswa.
Lawula ukucocwa, ixesha lokulinda lingalungiswa, inqanaba lokucocwa lingalungiswa. Iglu ingafakwa ngokuphindaphindiweyo kwiicocwa ezininzi. Isibane se-UV singafakwa ngokulula kumgca wemveliso okhoyo ngaphandle kotshintsho olukhulu.
4. Uluhlu olubanzi kakhulu lwesicelo kunye nesiphumo esihle sokubopha
Iglu ye-UV ineendlela ezininzi zokusebenza kwaye inemiphumo emihle kakhulu yokubopha phakathi kweplastiki kunye nezinto ezahlukeneyo. Inamandla aphezulu okubopha kwaye ingaphula umzimba weplastiki ngaphandle kokususa i-gum ngokusebenzisa iimvavanyo zokutshatyalaliswa. Iglu ye-UV ingafakwa kwimizuzwana embalwa, kwaye ifikelele kumandla aphezulu ngomzuzu omnye;
Ibonakala ngokucacileyo emva kokunyibilika, kwaye imveliso ayizukuba tyheli okanye ibe mhlophe ixesha elide. Xa ithelekiswa nokunamathela okukhawulezileyo kwendabuko, ineengenelo zokuxhathisa uvavanyo lokusingqongileyo, akukho mhlophe, ukuguquguquka okuhle, njl. Inobushushu obuphantsi obugqwesileyo, ubushushu obuphezulu kunye nokumelana nokufuma okuphezulu.
Isincamathelisi seglue se-UV se-SV 203 esilungisiweyo se-acrylate
I-SV 203 sisincamathelisi se-UV esiyinxalenye enye okanye esibonakalayo esikhanyiswayo. Isebenzisa ikakhulu izinto ezisisiseko zokubopha isinyithi neglasi. Isetyenziswa kwi-bonding phakathi kwentsimbi engatyiwayo, i-aluminium, kunye neeplastiki ezicacileyo, iglasi yendalo kunye neglasi yekristale.
