Yintoni ekufuneka uyazi malunga ne-UV yokuNyanga i-Optical Adhesives

Into yokuqala eyayiza kusetyenziswa njengento yokuncamathelisa ebonakalayo yayiyincindi ediyiweyo kumthi webhalsam. Yayibizwa ngokuba yiCanada Balsam, kwaye nangona ineempawu eziphezulu ze-optical, yayiswele ukunyibilika kunye nokumelana nobushushu. Izixhobo ezingcono ziya kuthi kamva zithathe indawo yayo ngenxa yoko. Ukusetyenziswa kwe-Optic kufuna ukusebenza okuphezulu kunye nemveliso; kungoko, uninzi lweenjineli zihlala zibhenela kwizinto zokuncamathelisa ze-UV.

Ngexesha lendibano ye-optical, kubaluleke kakhulu ukuba amacandelo ahlangane ukuze asebenze ngokufanelekileyo. I-adhesive enika ibhondi eyomeleleyo iyimfuneko kwi-prism kunye ne-lens bonding, i-fiber optic assembly, kunye nokulungiswa kunye nokubeka izinto ezibonakalayo. Izinto zokuncamathelisa ziza ngokwamandla ahlukeneyo kunye nezithintelo; kungoko kunokuba ngumceli mngeni kubantu abaninzi ukumisela ukuba zeziphi imathiriyeli eziyifanele kakhulu imisebenzi yokudibanisa ekhoyo. Ngelixa isalathiso se-refractive kunye nokuhanjiswa kwe-optical zezona ngqwalasela ziphambili xa ujongwa I-UV yokunyanga izinto zokuncamathelisa zamehlo, ingqwalasela ngenyameko kufuneka ithathelwe ukulinganisa iimpawu eziphathekayo ngokweemfuno zesicelo. Ezinye zezinto ekufuneka ziqwalaselwe ziquka:

Iimpawu zokuncamathelisa 

Ngexesha lokunyanga, uninzi lwezinto ezincamathelayo zidla ngokushwabana, kwaye oku kunokubangela uxinzelelo kwiindawo ezithile. Apho kukho uxinzelelo, ke ulungelelwaniso kunye nemiba yokugxila ayinakuphepheka ngexesha lokucubungula. Ngoko ke, kubalulekile ukuba iinjineli zizinze kwimathiriyeli enokuncipha okuncinci ukunciphisa imiba. I-epoxy adhesives, umzekelo, ingaba ne-5% ye-shrinkage. Nangona kunjalo, kukho i-adhesives ekhethekileyo ye-optical adhesives ephantsi njenge-0.4% ye-shrinkage kwaye isalawula ukugcina ukucaca okucacileyo okufunekayo.

Ngokuphathelele ukunyaniseka kwesakhiwo kunye nokusebenza kwayo, ukuqwalasela imodyuli kunye nobunzima bezinto zokubambelela nazo zibaluleke kakhulu. Ukukhuphela ngaphandle kufuneka kujongwe kuba ukuguquguquka okuthile kunokukhokelela kwimiba yobulunga.

Ukuphatha kunye nokunyanga 

Ezi zimbini zikwayingqwalasela ebaluleke kakhulu xa ujonge okona kulungileyo I-UV yokunyanga izinto zokuncamathelisa zamehlo. Indlela yokunyanga kunye nendlela echaphazela ngayo ubunzima kunye nesantya seprojekthi kufuneka ithathelwe ingqalelo. Ukunamathiswa kwe-UV kuthatha kuphela imizuzwana embalwa ukunyanga, okuluncedo kwiimeko apho kukho imfuneko yokuvelisa ngokukhawuleza. Nangona kunjalo, izixhobo ezahlukeneyo zithatha amaxesha ahlukeneyo ukunyanga. Umzekelo, ii-epoxies ezinamacala amabini zifuna ixesha elide lokunyanga xa kuthelekiswa ne-adhesives ye-silicone. Ngelixa ubushushu bunokuyikhawulezisa inkqubo, kubalulekile ukukhumbula ukuba uhambo olushushu lunokubangela uxinzelelo kwiindawo ezithile ngexesha okanye emva kokunyanga.

I-Viscosity nayo ibalulekile ngokwesicelo. Kwezinye izicelo, i-adhesive ifuneka kuphela ukuzalisa i-gap ethile okanye ibhuloho, kanti, kwezinye, kunokufuneka ukuba igcwalise yonke indawo. Ukuxuba kunye ne-degassing ingaba yinkqubo edinayo, ngakumbi kwiinkqubo zamacandelo amabini; kungoko kungafuneka izixhobo ezikhethekileyo ukuba zisetyenziswe.

Izinto zokuncamathelisa i-Acrylate ezinyangeka yi-UV zithandwa kwizicelo ze-optics kuba kulula ukuzisebenzisa. Bakwabonelela ngexesha lonyango elikhawulezayo kwaye lilungele uninzi lweemfuno zesicelo. Iinketho, nangona kunjalo, zininzi kwimarike, kwaye xa usazi ukuba zeziphi iimfuno zesicelo sakho, uya kuba nexesha elilula lokukhetha ezona zinto zincamatheleyo zinyangekayo zeUV. I-DeepMaterial yenza izinto zokuncamathelisa ezikumgangatho ophezulu ukuhambelana nazo zonke iintlobo zeemfuno. Vumela iingcali zokuncamathelisa kwi-DeepMaterial zikukhokele kweyona ncam ifanelekileyo yesicelo sakho.

Ukufumana okungakumbi malunga nento ekufuneka uyazi ngayo i-uv yokunyanga izinto zokuncamathelisa zamehlo,unokuhlawula utyelelo kwi-DeepMaterial kwi https://www.epoxyadhesiveglue.com/uv-curing-uv-adhesive/ ngolwazi olungakumbi.
