Cov Tshuaj Nplaum UV-Kho Lwm Yam

Ib tiam tshiab ntawm UV-curing silicones thiab epoxies tau siv ntau dua hauv kev siv tsheb thiab khoom siv hluav taws xob.
Txhua yam haujlwm hauv lub neej muaj kev sib pauv: Kev tau txais ib qho txiaj ntsig ntawm qhov raug nqi ntawm lwm qhov, kom ua tau raws li qhov xav tau ntawm qhov xwm txheej tam sim no. Thaum qhov xwm txheej cuam tshuam nrog kev sib txuas ntau, kev sib khi lossis gasketing, cov chaw tsim khoom vam khom cov nplaum UV-cure vim tias lawv tso cai rau kev kho sai thiab raws li qhov xav tau (1 txog 5 vib nas this tom qab raug lub teeb).

Txawm li cas los xij, qhov sib pauv yog tias cov nplaum no (acrylic, silicone thiab epoxy) xav tau cov khoom siv pob tshab kom sib txuas tau zoo, thiab lawv kim dua li cov nplaum uas kho tau los ntawm lwm txoj kev. Txawm li cas los xij, ntau lub tuam txhab tsim khoom hauv ntau lub lag luam tau zoo siab ua qhov kev sib pauv no tau ntau xyoo lawm. Ntau lub tuam txhab yuav ua li ntawd rau yav tom ntej. Txawm li cas los xij, qhov sib txawv yog tias cov engineers yuav siv cov nplaum silicone lossis epoxy UV-cure, ib yam li cov uas yog acrylic-based.

"Txawm hais tias peb tau ua cov silicones UV-cure rau kaum xyoo dhau los lossis li ntawd, hauv peb xyoos dhau los peb tau ua kom peb cov kev siv zog muag khoom kom ua tau raws li kev xav tau ntawm kev ua lag luam," Doug McKinzie, tus lwm thawj coj ntawm cov khoom tshwj xeeb ntawm Novagard Solutions tau hais. "Peb cov muag khoom silicone UV-cure tau nce 50 feem pua ​​​​​​ob peb xyoos dhau los. Qhov no yuav txo qee qhov, tab sis peb tseem xav tias yuav loj hlob zoo rau ob peb xyoos tom ntej."

Cov neeg siv cov tshuaj silicone UV-cured loj tshaj plaws yog cov tuam txhab OEM hauv tsheb, thiab cov neeg muag khoom Tier 1 thiab Tier 2. Ib tus neeg muag khoom Tier 2 siv Loctite SI 5031 sealant los ntawm Henkel Corp. los muab cov qhov rau hauv cov qhov rau cov modules tswj lub nres hluav taws xob thiab cov sensors siab ntawm lub log tsheb. Lub tuam txhab kuj siv Loctite SI 5039 los ua ib lub gasket silicone uas kho UV-cured nyob ib puag ncig ntawm txhua lub module. Bill Brown, tus thawj coj ntawm kev tsim kho rau Henkel, hais tias ob qho khoom muaj cov xim fluorescent los pab txheeb xyuas qhov muaj cov nplaum thaum lub sijhawm tshuaj xyuas zaum kawg.

Cov khoom sib dhos no ces raug xa mus rau tus neeg muag khoom Tier 1 uas muab cov khoom sab hauv ntxiv thiab txuas PCB rau cov davhlau ya nyob twg. Lub hau raug muab tso rau saum lub gasket perimeter kom tsim tau lub foob ruaj khov rau ib puag ncig ntawm qhov sib dhos kawg.

Cov nplaum epoxy UV-kho kuj tseem siv ntau rau kev siv hauv tsheb thiab cov khoom siv hluav taws xob rau cov neeg siv khoom. Ib qho laj thawj yog tias cov nplaum no, zoo li silicones, tau tsim tshwj xeeb los phim qhov ntev ntawm cov teeb pom kev zoo LED (320 txog 550 nanometers), yog li cov chaw tsim khoom tau txais txhua yam txiaj ntsig ntawm teeb pom kev zoo LED, xws li lub neej ntev, cua sov tsawg thiab kev teeb tsa yooj ywm. Lwm qhov laj thawj yog cov nqi qis dua ntawm kev kho UV, yog li ua rau nws yooj yim dua rau cov tuam txhab lag luam pauv mus rau cov thev naus laus zis no.
