WaterproofKev tsom xam ntawm sab nraum zoov LED teeb
Sab nraum zoov teeb pom kev zoo yuav tsum tiv taus qhov kev sim ntawm cov daus thiab dej khov, cua thiab xob laim, thiab tus nqi siab heev. Vim tias nws yog qhov nyuaj rau kev kho ntawm phab ntsa sab nrauv, nws yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm ruaj khov mus ntev. LED yog ib qho khoom siv semiconductor zoo heev. Yog tias nws ntub, cov nti yuav nqus cov dej noo thiab ua rau cov LED, PcB thiab lwm yam khoom puas. Yog li ntawd, lub LED yog tsim rau kom qhuav thiab tsis kub. Txhawm rau kom ntseeg tau tias lub sijhawm ua haujlwm ruaj khov ntawm LEDs nyob rau hauv qhov hnyav sab nraum zoov, cov qauv tsim qauv ntawm cov teeb pom kev zoo yog qhov tseem ceeb heev.
Tam sim no, cov cuab yeej siv hluav taws xob tsis zoo ntawm cov teeb hluav taws xob feem ntau yog muab faib ua ob qho kev qhia: cov txheej txheem waterproofing thiab cov khoom siv waterproofing. Lub thiaj li hu ua structural waterproofing yog hais tias tom qab kev sib txuas ntawm ntau yam structural Cheebtsam ntawm cov khoom, nws tau waterproof. Cov khoom siv yog tsis muaj dej tsis zoo, yog li ntawd thaum cov khoom tsim, txoj hauj lwm ntawm cov kua nplaum nplaum rau cov khoom siv hluav taws xob yog sab laug, thiab cov khoom siv kua nplaum yog siv rau cov dej tsis zoo thaum sib dhos. Ob qhov kev tsim cov dej tsis zoo no muaj rau cov khoom sib txawv, txhua tus muaj nws tus kheej zoo.
Cov yam ntxwv cuam tshuam rau kev ua haujlwm tsis zoo ntawm cov teeb
1, ultraviolet lub teeb
Cov kab hluav taws xob ultraviolet muaj kev puas tsuaj rau cov hlau rwb thaiv tsev, txheej txheej tiv thaiv, cov khoom yas, cov kua nplaum nplaum, lub nplhaib sealing roj hmab sawb thiab cov nplaum raug rau sab nraud ntawm lub teeb.
Tom qab txheej txheej rwb thaiv tsev hlau yog hnub nyoog thiab tawg, dej vapor yuav nkag mus rau sab hauv ntawm lub teeb los ntawm qhov sib txawv ntawm cov tub ntxhais hlau. Tom qab txheej txheej ntawm lub teeb vaj tsev yog hnub nyoog, txheej txheej ntawm ntug ntawm lub casing yog tawg los yog tev tawm, thiab qhov sib txawv yuav tshwm sim. Tom qab cov ntaub ntawv yas muaj hnub nyoog, nws yuav deform thiab tawg. Kev laus ntawm cov hluav taws xob potting gel ua rau tawg. Lub sealing rubber strip yog laus thiab deformed, thiab qhov sib txawv yuav tshwm sim. Cov nplaum nplaum ntawm cov tswv cuab ntawm cov qauv yog hnub nyoog, thiab qhov sib txawv kuj tsim tom qab qhov adhesion qis dua. Cov no yog tag nrho cov kev puas tsuaj rau lub peev xwm tsis muaj dej ntawm lub luminaire los ntawm ultraviolet lub teeb.
2, siab thiab qis kub
Qhov kub sab nraum zoov sib txawv heev txhua hnub. Nyob rau lub caij ntuj sov, qhov kub ntawm lub teeb tuaj yeem nce mus rau 50-60° C, thiab kub poob rau 10-20 qC thaum yav tsaus ntuj. Qhov kub ntawm lub caij ntuj no thiab daus tuaj yeem poob qis dua xoom, thiab qhov kub thiab txias hloov pauv ntau dua thoob plaws hauv lub xyoo. Sab nraum zoov teeb pom kev zoo nyob rau hauv qhov kub thiab txias ib puag ncig nyob rau hauv lub caij ntuj sov, cov khoom accelerates kev laus deformation. Thaum qhov kub thiab txias poob qis dua xoom, cov khoom yas ua nkig, nyob rau hauv lub siab ntawm dej khov thiab daus los yog tawg.
3, thermal expansion thiab contraction
Thermal expansion thiab contraction ntawm lub teeb vaj tsev: Qhov kub hloov ua rau lub thermal expansion thiab contraction ntawm lub teeb. Cov ntaub ntawv sib txawv (xws li iav thiab aluminium profiles) muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, thiab ob cov ntaub ntawv yuav raug tshem tawm ntawm qhov sib koom ua ke. Cov txheej txheem ntawm thermal expansion thiab contraction yog rov ua tsis tu ncua, thiab cov txheeb ze hloov chaw yog rov ua tsis tu ncua, uas ua rau muaj kev puas tsuaj rau airtightness ntawm lub teeb.
Sab hauv huab cua thermal expansion thiab contraction: Lub condensation ntawm cov tee dej ntawm lub faus lub teeb iav tuaj yeem pom nyob rau hauv cov square pem teb, thiab ua li cas cov tee dej nkag mus rau hauv lub teeb ntim nrog potting kua nplaum? Qhov no yog qhov tshwm sim ntawm kev ua pa thaum lub sij hawm thermal expansion thiab contraction.
4, tus qauv ntawm waterproof
Luminaires raws li cov qauv tsim dej tsis zoo yuav tsum tau nruj nruj nrog silicone sealing nplhaib. Lub txheej casing txheej yog ntau meej thiab nyuaj. Nws yog feem ntau haum rau cov teeb loj loj, xws li sawb dej nyab teeb, square thiab voj voog dej nyab, thiab lwm yam. Teeb pom kev zoo.
5, cov khoom siv waterproof
Kev tsim cov dej tsis zoo ntawm cov khoom siv yog insulated thiab waterproofed los ntawm filling potting kua nplaum, thiab kev sib koom ua ke ntawm cov txheej txheem kaw yog sib koom ua ke los ntawm cov kua nplaum sealing, kom cov khoom siv hluav taws xob yog tag nrho airtight thiab cov dej tsis zoo ntawm cov teeb pom kev zoo sab nraum zoov.
6, kua nplaum nplaum
Nrog rau kev txhim kho cov khoom siv tsis muaj dej tsis zoo, ntau hom thiab hom tshwj xeeb potting glues tau tshwm sim tsis tu ncua, piv txwv li, hloov epoxy resin, hloov polyurethane resin, hloov organic silica gel, thiab lwm yam. Cov qauv tshuaj sib txawv, lub cev thiab cov khoom siv tshuaj lom neeg ntawm potting roj hmab, xws li elasticity, molecular qauv stability, adhesion, anti-uV, kub tsis kam, tsis kub tsis kam, dej repellency thiab rwb thaiv tsev zog, yog txawv.
Xaus
Txawm hais tias cov khoom siv dej tsis zoo los yog cov khoom siv dej tsis zoo, rau lub sijhawm ntev kev ua haujlwm ruaj khov thiab tsis ua haujlwm ntawm cov teeb pom kev zoo sab nraum zoov, ib qho kev tsim dej tsis zoo yog qhov nyuaj rau kev ua tiav kev ntseeg siab heev, thiab qhov muaj peev xwm zais qhov phom sij ntawm dej seepage tseem muaj.
Yog li ntawd, tsim high-end sab nraum zoov LED teeb yog pom zoo kom siv waterproof technology los ua ke qhov zoo ntawm structural waterproofing thiab cov ntaub ntawv waterproofing technology los txhim kho lub sij hawm ntev stability ntawm LED Circuit Court. Yog tias cov khoom siv dej tsis zoo, nws tuaj yeem muab ntxiv rau lub tshuab ua pa kom tshem tawm qhov tsis zoo. Cov qauv tsim cov dej tsis zoo kuj tseem tuaj yeem suav hais tias yuav ua rau kom cov potting, ob chav dej tiv thaiv, txhim kho kev ruaj ntseg ntawm sab nraum zoov teeb pom kev zoo rau kev siv mus ntev, thiab txo tus nqi ntawm cov dej tsis zoo.
