Mabhenefiti eUV / LED Kurapa Adhesives

Ndechipi chikonzero chikuru chekushandisa LED kurapa zvinonamira pamusoro pe UV zvinorapika zvinonamira?

Ma LED anorapa anonamira anowanzo kurapa mumasekonzi 30-45 pasi pechiedza che405 nanometer (nm) wavelength. Chiedza chechinyakare chinorapa zvinonamira, nekusiyana, kurapa pasi pe ultraviolet (UV) magwenzi emwenje ane wavelengths pakati pe320 ne380 nm. Kune mainjiniya ekugadzira, kugona kurapa zvizere zvinonamira pasi pechiedza chinooneka kunovhura huwandu hwekubatanidza, encapsulation uye yekuisa chisimbiso maapplication ayo akange asina kufanirwa kune zvigadzirwa zvekurapa mwenje, nekuti mune akawanda maapplication ma substrates anogona kusafambisa mu UV wavelength asi anobvumira kuoneka. kufambisa kwechiedza

Ndezvipi zvimwe zvezvikonzero zvinogona kukanganisa nguva yekurapa?

Kazhinji, kusimba kwemwenje we LED kunofanirwa kunge kuri pakati pe1 uye 4 watts/cm2. Imwe fungidziro ndeye chinhambwe kubva kune mwenje kusvika kune yakanamatira layer, semuenzaniso, iyo iri kure nemwenje kubva kune yakanamatira, iyo yakareba nguva yekurapa. Zvimwe zvinhu zvinofanirwa kutariswa kukora kweiyo adhesive layer, nhete inorapa nekukurumidza kupfuura yakakora layer, uye kuti ma substrates ari pachena sei. Maitiro acho anofanirwa kukwenenzverwa kukwirisa nguva dzekurapa, zvichibva kwete chete pane geometries ega ega dhizaini, asiwo mhando yemidziyo inoshandiswa.

Iwe unoita sei shuwa kuti iyo LED inonamira yapora zvizere?

Kana chinonamira che LED chanyatsopora, chinoumba nzvimbo yakaoma uye isina-tacky ine girazi yakatsetseka. Nyaya yekuedza kusati kwaitwa kurapa parefu wavelengths idambudziko rinonzi oxygen inhibition. Kudzivirirwa kweokisijeni kunoitika kana okisijeni yemuchadenga ichimisa iyo yemahara-radical polymerization process inorapa anenge ese maUV anonamira. Zvinoita kuti pave netacky, zvishoma apora.

Oxygen inhibition inonyanya kutaurwa mumashandisirwo asina chipingamupinyi kumhepo yemhepo. Semuyenzaniso, inhibition yeokisijeni ingangove yakaipisisa muchirongwa chekuputira chine mushonga wakavhurika-mhepo kupfuura zvazvingave mukushandisa inoisa chinonamira pakati pemagirazi.

Ndeapi mamwe ekuchengetedza mabhenefiti ekunamira kwe LED achipikisa UV kurapa?

Magetsi eUV anogona kuunza nyaya yekuchengetedza sezvo aine mukana wekukonzera kupisa kweganda uye kukuvara kwemaziso; kunyangwe marambi eLED achiri kuda kushandiswa nemidziyo yekudzivirira yemunhu, anowanzo kusaisa mwero wengozi unoitwa nevamwe vavo veUV.

Ndeapi masisitimu akasarudzika anopihwa naMaster Bond iwo mushonga nemwenje we LED?

Master Bond LED 400 yakatevedzana inopa huwandu hweinodiwa einjiniya zvivakwa uye zvichienderana negiredhi, inogona kushandiswa kusungirira, encapsulation, uye coating. Chigadzirwa chitsva munhevedzano ndeye LED405Med.
