Kutheni Isibane se-UV Siba Sishushu Ngexesha Lenkqubo Yokunyanga?
2025-11-19
Kwimimandla yemizi-mveliso efana nokuprinta, ukupakisha, kunye nokufaka umthi, Unyango lwe-UV Itekhnoloji yamkelwe ngokubanzi ngenxa yokusebenza kwayo kakuhle, ukuba nobuhlobo nokusingqongileyo, kunye nomgangatho ogqwesileyo. Nangona kunjalo, nangona abasebenzisi bexhamla kubuchule bayo, badla ngokuqaphela kwaye baveze inkxalabo malunga namaqondo obushushu aphezulu abangelwa sisibane se-UV kunye neendawo ezisingqongileyo. Makhe sijonge kwimigaqo yesayensi engasemva kwesi simo.
Ukuguqulwa kwamandla sisizathu esiphambili:
Ingongoma ye Unyango lwe-UV kukusetyenziswa kwamaza athile okukhanya kwe-ultraviolet ukuze kuqalise ukudibana ngokukhawuleza kunye nokuphiliswa kwe-ii-inki okanye ii-coatings ezine-photoinitiators. Kule nkqubo, isibane se-UV sisebenza njengomthombo wamandla, siguqula umbane ongenayoamandla ikakhulu abe ziintlobo ezimbini: Eyokuqala yimitha ye-ultraviolet, enamandla asebenzayo abangela ukuphiliswaimpendulo. Okwesibini kukukhanya okubonakalayo kunye nemisebe ye-infrared; i-infrared isebenza njengemitha yobushushu, efunxwa zizinto kunyeiguquka ngokukhawuleza ibe ngamandla obushushu. Esi sisizathu esibalulekileyo sokunyuka okukhulu kobushushu emzimbeni wesibane kunyeokusingqongileyo okungqongileyo.
Isibane ngokwaso singumthombo wobushushu:
Xa sijonga izibane zemercury ezisetyenziswa kakhulu njengomzekelo, umgaqo wazo wokusebenza ubandakanya ukusebenzisa i-arc yombane enoxinzelelo oluphezulu.ngaphakathi kwityhubhu yesibane ukuze kuvuselelwe umphunga we-mercury, nto leyo ebangela ukuba ikhuphe ukukhanya. Ubushushu obuphakathi bale arc bunokufikelela kumawaka aliqelaiidigri Celsius. Nokuba ibekwe eludongeni lwetyhubhu ye-quartz, ubushushu bayo bokusebenza buhlala bufikelela kwi-600-800°C.Isibane esinjalo, esihlala sikhupha ubushushu obuninzi, ngokungathandabuzekiyo sinyusa ubushushu bendawo esikuyo ngokusebenzisa ubushushuimitha kunye ne-convection yomoya.
Impembelelo Ephindwe Kabini Yobushushu Obuphezulu:
Ubushushu obuphakathi bunokukhuthaza ukusabela kokuchacha, kodwa ubushushu obugqithisileyo buzisa iingxaki ezingaphezulu kuneenzuzo.ayibangeli nje kuphela ukuguquka kobushushu kwiiplastiki ezifana nePVC kunye nePET, okanye ikhokelele ekulahlekelweni komswakama kunye nokugoba kwi-substrates zephepha, kodwa inokubangelaikwabangela ukunyangwa komphezulu ngaphambi kwexesha, nto leyo ethintela ukunyangwa kwangaphakathi okunzulu kwaye enokuchaphazela ukunamathela. Ngaphezu koko, ukwanda kokunyangwaUbushushu obuphakathi kwindawo yokusebenzela buchaphazela intuthuzelo yokusebenza kwaye bongeza iindleko zokupholisa ezongezelelweyo.
Ulawulo loBushushu oluCwangcisiweyo luyisisombululo esiPhambili:
Ke ngoko, ubushushu obuphezulu yinto ebonakalayo kwinkqubo yokuguqula amandla onyango lwe-UV, hayi izixhoboukungasebenzi kakuhle. Ngenxa yoko, ulawulo lobushushu lwesayensi lubalulekile. I-high-high yanamhlanje Inkqubo ye-UVdibanisa izisombululo eziphambili ezifana nomoyaukupholisa, ukupholisa amanzi, kunye nezibonisi ezikhethekileyo ezipholileyo. Ezi zijolise ekukhuliseni ukukhanya kwe-UV ngelixa zilawula ngempumeleloubushushu obuvela kwi-infrared, ukuqinisekisa ukuphiliswa okusebenzayo ngelixa kunciphisa impembelelo yobushushu, ekugqibeleni kufezekisa ulungelelwaniso oluchanekileyo phakathi kokukhanya kunyeubushushu.
