Ua kom muaj kev nyab xeeb ntawm teeb pom kev zoo: Cov khoom siv hluav taws xob tsis zoo thiab tiv thaiv kev kub dhau
Hauv kev lag luam teeb pom kev lag luam hloov zuj zus sai, cov khoom lag luam kev nyab xeeb tseem yog qhov kev txhawj xeeb tseem ceeb. Raws li cov teeb ci ua ib qho tseem ceeb rau thaj chaw nyob, kev lag luam, thiab kev lag luam, kev nkag siab txog kev nyab xeeb ntawm hluav taws xob cuam tshuam nrog lawv cov khoom yas yog qhov tseem ceeb. Kab lus no tshuaj xyuas seb lub teeb vaj tsev thiab cov khoom yas sab hauv puas ua tau raws li cov qauv ntawm cov nplaim hluav taws thiab ntsuas qhov muaj peev xwm overheating thiab hluav taws kub.
1. Nplaim Retardancy Standards rau Teeb Plastics
Cov nplaim hluav taws kub yog hais txog cov khoom muaj peev xwm tiv thaiv hluav taws kub, hluav taws xob qeeb, thiab tus kheej - tua hluav taws thaum raug hluav taws. Rau kev siv teeb pom kev zoo, qhov twg cov khoom siv hluav taws xob ua kom sov, cov cuab yeej no ua qhov tseem ceeb rau kev nyab xeeb.
Cov txheej txheem thoob ntiaj teb tswj cov khoom yas hauv cov teeb pom kev zoo suav nrog:
UL94 ntawv pov thawj: Qhov ntsuas ntsuas no ntsuas cov khoom siv hluav taws xob, nrog rau kev faib tawm ntawm V-0 (siab tshaj plaws tiv thaiv, tua tsis pub dhau 10 vib nas this) mus rau V-2. Cov teeb pom kev zoo tshaj plaws feem ntau xav tau V-0 lossis V-1 kev ntsuas.
IEC 60598 (TSI): Cov txheej txheem teeb pom kev zoo ntawm kev nyab xeeb no tau txiav txim siab tias cov ntaub thaiv npog thiab cov khoom tseem ceeb yuav tsum ua kom pom cov nplaim hluav taws txaus, tshwj xeeb tshaj yog nyob rau hauv qhov kub siab -.
Cov nplaim hluav taws zoo sib xws-cov yas retardant hauv cov teeb pom kev zoo muaj xws li:
Polycarbonate (PC): Muaj kev tiv thaiv kub zoo (feem ntau yog 120-}130 degree) thiab cov nplaim hluav taws kub nyhiab, ua rau nws zoo tagnrho rau cov ntawv siv kub xws li LED vaj tsev.
ABS: Thaum tsis muaj nplaim taws- rov qab, hloov ABS nrog cov khoom siv ntxiv tuaj yeem ua tiav UL94 V-0 kev faib tawm thaum tuav cov kev cuam tshuam zoo.
Thermoplastic Polyesters (PBT/PET): Cov ntaub ntawv no muab kev tiv thaiv zoo rau ob qho tib si kub thiab nplaim taws, feem ntau siv hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.
2. Kev ntsuas kub thiab hluav taws kub
Txawm tias muaj cov ntaub ntawv tsim nyog, ntau yam tuaj yeem tsim teeb meem hluav taws:
Cov teeb meem hluav taws xob: Cov tsav tsheb ntau dhau, kev sib txuas tsis zoo, lossis cov khoom siv hluav taws xob tsis zoo tuaj yeem tsim kom muaj cua sov ntau dhau, uas tuaj yeem cuam tshuam cov khoom nyob ze.
Tsis txaus Thermal Management: LED tsav tsheb thiab chips ua kom muaj cua sov loj. Yog tsis muaj cua sov los yog qhov cua kom zoo, qhov kub thiab txias tuaj yeem nce mus rau qib txaus ntshai.
Environmental Stressors: Kev teeb tsa hauv qhov chaw kaw, qhov kub thiab txias, lossis qhov cua tsis zoo tuaj yeem thawb lub teeb dhau ntawm lawv qhov kev txwv thermal.
Tsis yog -Cov ntaub ntawv ua raws: Cov yas tsis muaj ntawv pov thawj los yog siv dua tshiab tuaj yeem deform, yaj, lossis ignite ntawm qhov kub thiab txias.
3. Cov tswv yim txo kev pheej hmoo
Txhawm rau kom muaj kev nyab xeeb thoob plaws lub teeb lub neej:
Rau Manufacturers:
Ua raws li cov txheej txheem xaiv cov khoom nruj me ntsis uas yuav tsum tau muaj ntawv pov thawj UL94 V-0 rau vaj tse
Tsim cov txheej txheem kev tswj xyuas thermal zoo nrog cov cua sov txaus
Ua kom tiav cov tshuab suav nrog cov tsav tsheb, tsis yog cov khoom siv ib leeg xwb
Ua qhov kev sim nruj raws li qhov phem tshaj - xwm txheej xwm txheej
Rau cov neeg siv khoom thiab Specifiers:
Ua pov thawj thib peb -cov ntawv pov thawj (UL, CE, TÜV) ua ntej yuav khoom
Ua raws li cov chaw tsim khoom cov txheej txheem hais txog cov khoom siv thiab cov chaw ua haujlwm
Txhim kho cov teeb ci hauv qhov dej zoo- qhov cua kom deb ntawm cov khoom siv hluav taws xob
Ua tsis tu ncua kev tshuaj xyuas kom tsis muaj xim, deformation, lossis ntxhiab tsw txawv
4. Cov lus xaus
Kev nyab xeeb hluav taws ntawm cov khoom siv teeb pom kev zoo yog nyob ntawm kev xaiv cov nplaim hluav taws uas tsim nyog- cov khoom siv retardant thiab siv cov qauv thermal zoo. Thaum cov yas niaj hnub zoo li PC thiab nplaim taws- ABS retardant muab kev tiv thaiv zoo, lawv cov txiaj ntsig yog nyob ntawm daim ntawv thov engineering thiab kev tswj kom zoo. Los ntawm kev paub txog kev tsim khoom thiab kev paub xaiv cov khoom lag luam, kev lag luam teeb pom kev zoo tuaj yeem txuas ntxiv muab cov kev daws teeb meem tshiab thaum tswj hwm cov qauv kev nyab xeeb siab tshaj plaws rau cov neeg siv khoom.
