Kufanele ubheke ama-resin aqukethe ama-initiators afana ne-TPO noma i-BAPO, aklanyelwe ukubamba amandla ebangeni ...

Inqubo yokuphulukisa i-UV yobuchwepheshe bokunamathisela iqukethe izinyathelo ezine eziyisisekelo: Isicelo Sokunamathisela: I-glue ezwela ukukhanya noma i-UV adhesive ibekwe ebusweni bokubopha, okungaba ingilazi, ipulasitiki, insimbi, noma izinhlanganisela. Ukuqondanisa: Izakhi zibekwa endaweni ngendlela eqondile kakhulu ukuze kufinyelelwe ngisho nokuxhumana phakathi kwezingqimba zokunamathisela. Ukuchayeka kokukhanya kwe-UV: Uhlelo lokuphulukisa lwe-UV LED noma uhlelo lwesibani sokuphulukisa i-UV luwumthombo wama-wavelengths athile (imvamisa i-365nm noma i-395nm) ukwenza kusebenze ama-photoinitiators. Ukwelapha nokuqina: I-photopolymerized adhesive ithatha imizuzwana embalwa ukwelapha, futhi ingaphulukisa ngokuphelele ngobuqotho obuvelele besibopho esivelele. Yonke inqubo izosusa ukusetshenziswa kokuphulukisa ukushisa noma isikhathi eside sokumiswa futhi inikeze ubuchwepheshe bokunamathisela obusheshayo, obuthuthukisa ukusebenza kahle kokukhiqiza futhi bunciphise ukusetshenziswa kwamandla. UV-Curable Adhesives are of various types I-UV-Epoxy Resins Izinamathiselo ezenziwe nge-epoxy zilungele kakhulu ukubopha kwesakhiwo lapho kudingeka khona amandla aphezulu okubopha lapho usebenza ngokukhanya kwe-UV. Esinye sezicelo ezijwayelekile ekwenzeni i-elekthronikhi nasekukhiqizeni izimoto. I-Acrylic Acids, Ukunamathela Okuphulukisayo kwe-UV Ama-Acrylics nawo ayaziwa ukuthi anejubane eliphakeme le-ejenti yokubopha kanye nokuphulukiswa kokushisa okuphansi kwe-UV, okusetshenziselwa ukubopha i-lens optical kanye nokukhiqizwa kwezingxenye zepulasitiki. Izindlela zokusebenzisa i-UV-Curable Pressure-Sensitive Adhesives (PSA) Lezi zinamathelayo zingasetshenziswa emaphaketheni nasezinhlosweni zokulebula, futhi zinikeze izixazululo ezisheshayo ekuhlanganisweni kwe-UV ezingenakukhishwa futhi zingagugi.  I-Polyurethane ne-UV-Curable silicone Adhesives Ukusetshenziswa kwazo kuyaguquguquka, kunembile ekuhlanganisweni kwe-UV, futhi kuyahambisana ne-biocompatible; lokhu kubenza babe balulekile ezinqubweni zokubopha i-aerospace namadivayisi wezokwelapha. ...

Ukufeza ukwelashwa kwezimboni okuphezulu kuncike ekuqondaneni okuqondile phakathi komthombo wakho wokukhanya kanye namakhemikhali wezinto zakho. Uzothola ukuthi nje ukuba nesibani esinamandla akwanele; Ukukhanya kufanele "kulungiswe" kumakhemikhali athile aklanyelwe ukuqinisa ama-inki akho noma ama-adhesives. Lo mhlahlandlela uchaza ukuthi ungaqhathanisa kanjani ama-photoinitiators kuma-wavelengths e-UV LED ngokuhlola i-spectra yokumuncwa namaphrofayli wamandla. Ngokuqonda lokhu kubhangqa kwezobuchwepheshe, ungaqinisekisa isivinini sokukhiqiza esisheshayo, izibopho eziqinile, kanye nenqubo yokukhiqiza enokwethenjelwa kakhulu. Kusho ukuthini ukufanisa ama-photoinitiators kuma-wavelengths e-UV LED? Ukufanisa ama-photoinitiators kuma-wavelengths e-UV LED kusho ukukhetha abaqalayo abaneziqongo zokumuncwa ezihlangana nebanga lokukhishwa kwe-LED. Kufanele uqinisekise ukuthi "umbala" othile wokukhanya kwe-ultraviolet okhishwa ngama-diode akho imvamisa efanayo ne-photoinitiator yakho eyenzelwe ukuyibamba. Ngoba ama-LED akhipha ibhande elincane kakhulu lokukhanya - ngokungafani ne-spectrum ebanzi yezibani zendabuko - lokhu kugqagqana kubalulekile. Uma okukhiphayo LED iwela ngaphandle kwewindi lokumuncwa komqalisi, amandla azodlula ezintweni ngaphandle kokuvusa inqubo yokuqina, kungakhathaliseki ukuthi isibani sinamandla kangakanani. Ama-photoinitiators asebenzisana kanjani nokukhanya kwe-UV? Ama-photoinitiators asebenza ngokumunca ama-wavelengths athile e-UV futhi aguqule lawo mandla abe ngama-radicals noma ama-ion aqala i-polymerization. Lapho uveza ukumbozwa kwakho uketshezi emvamisa efanele ye-UV, ama-molecule we-photoinitiator athatha ama-photon futhi angene esimweni esisebenzayo kakhulu. Lokhu kudluliswa kwamandla kuphula izibopho zamakhemikhali ngaphakathi kwe-initiator, ukudala izinhlobo ezisebenzayo ezidingekayo ukuxhuma ama-monomers kuchungechunge oluqinile lwe-polymer. Ungabuka i-photoinitiator njenge "spark plug" yokusabela kwamakhemikhali; kudinga ...

Enye inqubo esebenzisa ama-diode akhipha ukukhanya kwe-UV (ama-LED) ukuphrinta kwe-UV LED, lapho ama-inki azwela i-UV ephulukiswa khona ngokushesha ngokukhanya kwe-Ultraviolet (UV) njengoba inqubo yokuphrinta iqhubeka. Lokhu kungenye indlela yokuphulukisa okushisayo kwendabuko, njengoba le ndlela ihilela ukukhanya kwe-UV okugxile hhayi ukushisa, futhi izinto zokwakha, empeleni, azilimalanga. Izinzuzo ezinkulu zemishini yokuphrinta yilezi: Ukuphrinta kwe-inkjet ye-UV LED kanye nokuphrinta kwedijithali kwe-UV LED kuye kwavumela izimboni ukuthi zisebenzise ukunemba kokuphrinta kwe-UV kuma-substrates amaningi, kokubili okuyisicaba ne-3D. Lo mklamo wenze ubuchwepheshe bokuphrinta bulungele ukupakisha, izimpawu, i-elekthronikhi, izindwangu, izinto zokuphromotha nemishini yezokwelapha.  Ubuchwepheshe ngemuva kwe-UV LED Printing Ingxenye esemqoka ezinhlelweni zokuphrinta ze-UV LED inqubo yokwelapha ye-UV LED, lapho i-wavelength elawulwayo isetshenziselwa ukwelapha ama-inki we-UV. Ama-wavelengths e-UV LED athandwa kakhulu asetshenziselwa ukuphrinta yilezi: I-365nm UV LED: Ukunamathela nemininingwane emihle. Ukwelashwa okujulile.

Izwe lanamuhla lesayensi ye-forensic alikaze libe khona ngaphandle kokuqanjwa kokubonakala kobuchwepheshe obusha. Ukuhlaziywa kwe-UV ye-Forensic kungashiwo njengokunye kobuchwepheshe obunamandla kakhulu obusetshenziswa ngempumelelo emhlabeni wanamuhla. I-Mechanism: Isebenza kanjani Lapho izinto eziphilayo noma zamakhemikhali zisabela ngokukhanya kwe-UV, i-fluorescence yenzeka. Le miphumela ekhazimulayo iveza amabala, izinsalela, noma ukuguqulwa okungabonakali ngaphansi kokukhanya okujwayelekile. Ngosizo lwale ndlela, igazi nolunye uketshezi lomzimba, i-fiber, ngisho namaphepha akhohlisayo angatholakala. Enye yezinzuzo ezinkulu zokuhlaziywa kwe-ultraviolet ye-forensic isuselwa ekuntuleni ukuhlasela nokubhubhisa. Ngaphandle kwalokho, ngaphansi kwezivivinyo ezinamandla ezenziwa ngokusebenzisa amakhemikhali, ukuhlaziywa kwe-UV akuphazamisi ubufakazi. Lokhu kuzosiza abaphenyi ukuthi bagcine ubuqotho bamasampula azohlolwa kuma-laboratories futhi angasetshenziswa ezinkambisweni zomthetho. Ngaphansi kwenqubo yokuhlola yamathuluzi wokuhlaziya i-UV spectrum, njengoba ososayensi be-forensic babakhanyisa ngobufakazi, isidoda, igazi, amathe, imicu, noma izidakamizwa zizobonakala futhi zizonikeza ukubukeka kokukhanya ngenxa ye-fluorescence. Lokhu kungenxa yokuthi lolu hlobo lwezinto lumunca ukukhanya kwe-UV futhi lukhipha ukukhanya ekukhanyeni okubonakalayo. Amakilasi wemithombo yokukhanya kwe-UV Izinhlobo ze-Forensics Ukuhlaziywa kwe-forensic ultraviolet kusekelwe emandleni okunikeza ubufakazi obungabonakali kusetshenziswa ukukhanya okuhlukile kwe-ultraviolet. Uhlobo ngalunye lomthombo wokukhanya kwe-UV lunezici zalo ezithile, amandla nezingqinamba. I-UV inamandla, futhi inganikeza ukukhishwa kwe-fluorescent kakhulu ezintweni ezithile. Kuhle kakhulu maqondana nezinsalela zokulandela umkhondo kanye nama-minutiae. Kodwa-ke, ukuvezwa ngokweqile kwe-UV ye-short-wave kuye kwafakazelwa ukuthi kubhubhisa ubufakazi bezinto eziphilayo, kufaka phakathi i-DNA, futhi bekungeke kufakazele ukuthi kunenzuzo enkulu ...
