Yikuphi ukuqina kwe-UV engikudingayo ukuze ngiphulukishe? (W / cm² Kuchaziwe)

Ukunquma ukuthi yikuphi ukuqina kwe-UV engikudingayo ekwelapheni kuyisinyathelo esibalulekile ekuthuthukiseni noma iyiphi inqubo ye-ultraviolet yezimboni. Uzothola ukuthi ukuqina komthombo wakho wokukhanya kuchaza ukuthi ama-photoinitiators kuma-resin akho aqhutshwa kanjani, athinta ngqo ijubane lakho lokukhiqiza nekhwalithi yengxenye.

Lo mhlahlandlela uchaza incazelo yezobuchwepheshe yokuqina ($W / cm ^ 2 $), ubudlelwano bayo nomthamo wamandla, kanye nezici ezisebenzayo ezithinta ukuthi kungakanani amandla afinyelela ku-substrate yakho. Ngokuqonda lawa mamethrikhi, ungacacisa kangcono imishini yakho futhi uqinisekise ukwelashwa okuthembekile, okuphindaphindwayo kohlelo lwakho lokusebenza oluthile.

Kusho ukuthini ukuqina kwe-UV (w / cm²) ngempela?

Ukuqina kwe-UV, okulinganiswa ngama-watts ngesentimitha lesikwele ($W / cm ^ 2 $), kuchaza ukuthi kungakanani amandla e-UV uhlelo lokuphulukisa oluletha indawo ngayinye ngesikhathi esithile. Ungacabanga ukuqina ngokuthi "ukukhanya" noma "ingcindezi" yokukhanya kwe-UV eshaya ubuso bengxenye yakho. Kuyisilinganiso esisheshayo sobuningi bamandla, esimele ukuhlushwa kwama-photon atholakalayo ukuqala ukusabela kwamakhemikhali. Ngokungafani namandla aphelele, ukuqina kukutshela amandla okukhanya ebangeni elithile lokusebenza kusuka ekhanda lesibani, okubalulekile ekunqobeni ukuvinjelwa kwe-oksijini ezimweni ezithile.

Ukuqina kuthinta kanjani inqubo yokuphulukisa?

Ukuqina kwe-UV kuthonya ukuthi impahla ingaphulukisa ngokushesha futhi ngokufanayo kanjani ngoba amandla alethwa nganoma yisiphi isikhathi athinta isilinganiso sokuphendula kwe-photochemical. Uzothola ukuthi amazinga aphezulu okuqina avame ukuholela ku-polymerization esheshayo, engasekela isivinini esiphakeme sokuhambisa kanye nokwanda kwe-throughput. La mandla asheshayo yiwo "ashaqisayo" ama-photoinitiators esimweni esisebenzayo, ukuqinisekisa ukuthi ukwelashwa kuqala ngokungaguquguquki kuyo yonke indawo yokumboza kwakho. Amazinga afanele okuqina nawo asiza ekufezeni ubulukhuni obungcono bendawo ngokuqinisekisa ukuthi ungqimba oluphezulu lubeka ngaphambi kokuthi i-oksijini yasemkhathini iphazamise amakhemikhali.

Ukuqina kwe-UV kuhluke kanjani kumthamo we-UV?

Umthamo we-UV, olinganiswa ngama-joules ngamasentimitha ayisikwele ($J / cm ^ 2 $), uhlanganisa ukuqina nesikhathi sokuchayeka, kanti ukuqina kukodwa kulinganisa amandla asheshayo. Kufanele uhlukanise phakathi kwalaba bobabili ngoba isibani esinamandla kakhulu esisetshenziswe ingxenyana yomzuzwana singaletha umthamo ofanayo nesibani esincane esisetshenziswe imizuzwana embalwa, kepha imiphumela yokwelapha ingahluka ngokuphelele. Ukuqina kunikeza "inhlansi" ukuqala ukusabela, kuyilapho umthamo umele inani eliphelele lamandla adingekayo ukuqedela inqubo yokuqina kulo lonke ubukhulu bezinto ezibonakalayo.

Yimaphi amazinga okuqina ajwayelekile ekwelapheni i-UV LED?

Ukuqina okujwayelekile kokuphulukisa kwe-UV LED kungahluka kakhulu ngokuya ngomklamo wohlelo, isivinini senqubo, nezidingo zezinto ezibonakalayo, ngezinhlelo zezimboni ezilinganiselayo ezivame ukucaciswa kumabhendi athile we-$W / cm ^ 2 $. Ungase ubone izinhlelo zokungena noma zezandla ezihlinzeka ngamandla aphakathi kuka-1 no-4 $W / cm ^ 2 $, okwanele ukunamathela okuningi kwefilimu encane namajazi acacile. Imigqa ezenzakalelayo enejubane eliphezulu, njengaleyo esetshenziselwa ukuphrinta kwedijithali noma amalebula wewebhu amancane, imvamisa idinga ukuqina okuphezulu kakhulu, kwesinye isikhathi idlula i-16 noma i-20 $W / cm ^ 2 $, ukuqinisekisa ukwelashwa okugcwele ngaphakathi kwewindi elincane kakhulu lokuvezwa.

Kufanele ufanise kanjani ukuqina nezinto ezibonakalayo nesicelo?

Ukulinganisa ukuqina kwezinto ezibonakalayo kanye nesicelo kuhilela ukuqonda ukuzwela kokwelashwa kwezinto nokulinganisa ukuqina nesikhathi sokuchayeka nesivinini sokunyakaza. Kufanele ngaso sonke isikhathi uqale ngokubuyekeza ishidi ledatha lobuchwepheshe le-inki yakho ethile noma ukunamathela ukukhomba amazinga we-irradiance anconyiwe ngumkhiqizi.

• Izidingo Zokucwaninga Izinto Zokucwaningwa: Khomba ubuncane be-$W / cm ^ 2 $ edingekayo ukuze uqalise ama-photoinitiators akho athile.
• Hlola ijubane lomugqa: Bala ukuqina okudingekayo ngokuya ngokuthi ingxenye ngayinye izohlala isikhathi esingakanani ngaphansi kwesibani.
• Ukuhlolwa kobulukhuni be-surface: Qinisekisa ukuthi ukuqina kuphakeme ngokwanele ukunqoba ukuvinjelwa kwe-oksijini ukuze kuqedwe okungena-tack.
• Hlola ukujula kokungena: Qinisekisa ukuthi ukuqina kwanele ukuhamba ngezingqimba ezinemibala noma ezijiyile.
• Run Ladder Studies: Yenza izivivinyo emazingeni ahlukahlukene okuqina ukuthola "iwindi lenqubo" elihle.

Yikuphi ukucatshangelwa okusebenzayo okuthinta ukulethwa kokuqina?

Ukulethwa okusebenzayo kokuqina kwe-UV kuncike ezintweni ezifana nokufana kwamandla endaweni ehlosiwe, ukulawulwa kokushisa kwesibani, isu lokupholisa, nokuhlelwa kohlelo. Uzobona ukuthi njengoba ikhanda lesibani liya kude nengxenye, ukuqina kwehla kakhulu; Ukugcina ibanga lokusebenza eliqhubekayo kubalulekile kwinqubo ephindaphindwayo. Ngaphezu kwalokho, uma uhlelo lwakho lokupholisa lunganele, ama-diode e-LED angashisa, okwenza ukuqina kwawo kokukhiphayo kuwole ngesikhathi sokushintsha kokukhiqiza. Idizayini ye-optical yesibani ibuye inqume ukuthi amandla agxile kanjani ezingxenyeni zakho.

Yimiphi imibono eyiphutha okufanele uyigweme mayelana nokuqina kwe-UV?

Imibono eyiphutha ejwayelekile ifaka phakathi ukucabanga ukuthi ukuqina okuphezulu kuhlale kuthuthukisa ukwelashwa noma ukuthi ukuqina kukodwa kunquma impumelelo yokuphulukisa ngaphandle kokucabangela umthamo, amakhemikhali wezinto ezibonakalayo, noma ukufana. Ungase ucabange ukuthi ukuphinda kabili ukuqina kuzokuvumela ngokuzenzakalelayo ukuthi uphindwe kabili ijubane lomugqa wakho, kepha ezinye izinto zinephuzu "lokugcwala" lapho ukuqina okwengeziwe kumane kukhiqize ukushisa ngokweqile ngaphandle kokusheshisa ukwelashwa. Elinye iphutha elivame ukuncika ngokweqile ekuqineni kwesibani esiphezulu; Eqinisweni, ukuqina ebusweni bengxenye kuvame ukuba phansi kakhulu ngenxa yebanga nokusebenza kahle kwe-lens.

Yiziphi izinto ezibalulekile ezithathwayo ekuqineni kwe-UV ekwelapheni?

Ukufeza ukwelashwa okuphelele kudinga ukuthi uphathe ukuqina kwe-UV njengengxenye ye-equation enkulu yezobuchwepheshe. Uthola imiphumela emihle kakhulu lapho ufanisa amandla asheshayo esibani sakho nezidingo zamakhemikhali zezinto zakho kanye nejubane lomshini womugqa wakho.

• Ukuqina ($W / cm ^ 2 $) ngamandla asheshayo; Umthamo ($J / cm ^ 2 $) ngamandla aphelele.
• Ukuqina okuphezulu kuvame ukusekela isivinini somugqa osheshayo nobulukhuni obungcono bendawo.
• Ukuqina okusebenzayo engxenyeni yehla njengoba ibanga lokusebenza likhuphuka.
• Njalo qinisekisa inqubo yakho nge-radiometer ukuqinisekisa ukulethwa kwamandla okungaguquguquki.

Yiziphi izincazelo okufanele uzibheke ohlelweni lokuphulukisa lwe-UV LED?

Ukuqina kumane nje kuyingxenye eyodwa yephazili. Ungafunda ukuthi kuhlobene kanjani namandla, ukupholisa, kanye ne-footprint kumhlahlandlela wethu ku UV LED ukuphulukisa uhlelo specs.

How is UV LED dose calculated from intensity?
