Nrog rau kev ua kom tob zuj zus ntawm kev lag luam, cov khoom siv hluav taws xob tau tsim kho sai hauv cov kev taw qhia ntawm miniaturization, kev koom ua ke thiab precision. Qhov kev sib txawv ntawm qhov tseeb no ua rau cov cuab yeej tsis yooj yim dua, thiab txawm tias qhov txhaum me me tuaj yeem cuam tshuam rau nws txoj haujlwm ib txwm muaj. Tib lub sijhawm, daim ntawv thov scenarios ntawm cov khoom siv hluav taws xob kuj nthuav dav. Los ntawm Gobi, suab puam mus rau dej hiav txwv, cov khoom siv hluav taws xob muaj nyob txhua qhov chaw. Nyob rau hauv cov xwm txheej huab cua no, yuav ua li cas thiaj li tiv taus qhov hnyav xws li hluav taws xob ultraviolet, kub raug, acid nag yaig, thiab lwm yam tau dhau los ua qhov teeb meem ceev uas yuav tsum tau daws.
Adhesives, hu ua "kev lag luam MSG", tsis tsuas yog muaj cov khoom sib txuas zoo, tab sis kuj muaj qee lub zog thiab tawv tom qab kho, yog li nws kuj yog cov khoom siv tiv thaiv zoo heev.Potting & Encapsulation, raws li cov nplaum nplaum nrog cov khoom ntws, nws lub luag haujlwm tseem ceeb yog ua kom muaj txiaj ntsig zoo ntawm cov khoom sib xyaw ua ke, nruj nreem qhwv cov khoom, thiab tsim kom muaj kev tiv thaiv muaj zog. Txawm li cas los xij, yog tias xaiv cov nplaum nplaum uas tsis tsim nyog, nws cov nyhuv yuav raug txo kom tsawg.
Tej Teeb Meem
Tej teeb meem ntawmhluav taws xob potting nplaumyog raws li nram no:
Brittleness
Debonding
Daj
1. Brittleness: Lub colloid maj poob nws elasticity thiab tawg nyob rau hauv lub sij hawm ntev kub thiab high humidity ib puag ncig.
2. Debonding: Cov qauv colloid maj mam tshem tawm ntawm qhov chaw ntawm lub thawv sib txuas, ua rau kev sib txuas tsis ua haujlwm.
3. Yellowing: Ib qho tshwm sim ntawm kev laus uas cuam tshuam rau cov tsos thiab kev ua haujlwm.
4. Kev ua haujlwm tsis zoo ntawm rwb thaiv tsev: ua rau hluav taws xob tsis ua haujlwm thiab cuam tshuam rau kev nyab xeeb ntawm lub cev.
Cov nplaum nplaum zoo yog qhov tseem ceeb.
Zoo heev silicone potting nplaum yog tus yuam sij los daws qhov teeb meem!
Nrog nws cov huab cua tsis zoo thiab ua haujlwm ntev, silicone potting nplaum tuaj yeem tiv thaiv cov khoom siv hluav taws xob tau ntev, yog li txuas ntxiv lawv lub neej kev pabcuam.SIAV's hluav taws xob thermal conductive potting nplaumTsis tsuas yog muaj cov haujlwm tseem ceeb ntawm cov nplaum, tab sis kuj muaj cov huab cua zoo heev thiab kev laus ua haujlwm, feem ntau suav nrog cov hauv qab no:
Rwb thaiv tsev thiab thermal conductivity nplaim retardant kev ua tau zoo: Zoo tiv thaiv sab hauv ntawm lub thawv sib txuas kom tiv thaiv kev sib tsoo xws li luv luv Circuit Court hlawv.
Waterproof thiab noo noo-proof: Tiv thaiv kom tsis txhob muaj dej vapor nkag mus rau sab hauv ntawm lub thawv sib txuas kom tsis txhob muaj teeb meem xws li hluav taws xob luv luv.
Kev sib txuas zoo heev: Kev sib raug zoo zoo rau cov ntaub ntawv xws li PPO thiab PVDF.
Txhawm rau ntsuas qhov ua tau zoo ntawm potting nplaum, kev kuaj kev laus yog qhov tseem ceeb. Hauv kev lag luam, kev kuaj kev laus muaj xws li: UV aging, kub thiab txias cycles, kub thiab txias shock, kub thiab high humidity aging (feem ntau 85 ℃, 85% RH, ob 85), thiab high speedd kub thiab av noo kev nyuaj siab kuaj ( High Accelerated Stress Test, HAST). Muab ob npaug rau 85 thiab HAST yog ob txoj kev kuaj kev laus sai thiab zoo tshaj plaws. Lawv tuaj yeem nrawm nrawm cov khoom laus los ntawm qhov chaw huab cua ntawm cov av noo, cua sov thiab siab siab, kwv yees lub neej thiab kev ntseeg siab ntawm cov khoom hauv ib puag ncig sib txawv, thiab muab lub hauv paus rau cov khoom tsim thiab kev ua kom zoo.
Zoo los tsis yog, tsuas yog kev sim tuaj yeem qhia tau
Cia peb saib SIWAYsilicone potting nplaumkev ua tau zoo hauv ob chav 85 thiab HAST kev xeem.
Ob chav 85 xeemfeem ntau yog hais txog kev kuaj kev laus sai ntawm 85 ° C thiab 85% txheeb ze av noo. Qhov kev sim no yog tsim los simulate cov xwm txheej ntawm kev siv cov khoom siv hluav taws xob mus sij hawm ntev hauv qhov chaw ntub thiab kub kub los ntsuas lawv qhov kev ua tau zoo thiab kev ntseeg tau.
HAST (Humidity Accelerated Stress Test)yog ib qho kev ntsuam xyuas kev laus, feem ntau ua nyob rau hauv qhov kub thiab txias thiab cov av noo siab kom ceev cov txheej txheem kev laus ntawm cov khoom thiab cov khoom.
1. Cov tsos mob hloov pauv:
Tom qab muab ob npaug rau 85 1500h thiab HAST 48h kev xeem, qhov saum npoo ntawm cov qauv yuav tsis tig daj, thiab yuav tsis muaj qhov puas tsuaj los yog tawg. Nws yog ib qho tseem ceeb rau kev ua haujlwm mus sij hawm ntev ntawm cov tshuab hluav taws xob kom zoo tiv thaiv kev cuam tshuam ntawm lwm yam ntawm nws cov tsos nyob rau hauv qhov kub thiab txias thiab high humidity tej yam kev mob.

2. Adhesion peev xwm:
Tom qab muab ob npaug rau 85 1500h thiab HAST 48h kev xeem, lub peev xwm adhesion ntawm SIWAY silicone potting nplaum tseem zoo. Nws muaj adhesion zoo heev nyob rau hauv ib puag ncig huab, uas tuaj yeem ua kom muaj kev tiv thaiv dej tsis zoo thiab noo noo-pov thawj hauv cov khoom tseem ceeb ntawm lub cev thiab xyuas kom meej tias cov khoom siv hluav taws xob tiv thaiv tau ntev.
3. Lub cev muaj zog thiab hluav taws xob:
Tom qab ob chav 85 thiab HAST aging kev ntsuam xyuas, lub cev mechanical thiab hluav taws xob zog ntawm Silicon siway yog khaws cia nyob rau theem siab. Nws muaj lub siab tawv, elasticity thiab rwb thaiv tsev ua haujlwm. Nws tuaj yeem tiv thaiv qhov chaw sab nraud hauv qhov chaw huab cua thiab muab kev tiv thaiv zoo rau cov khoom siv hluav taws xob.
