2. Kev ntsuam xyuas kev ua tau zoo:

Creep, qaug zog lub zog, cuam tshuam tsis kam, durability, laus kev ua tau zoo, ntsev tsuag tshuaj ntsuam thiab lwm yam.

• ntsev tsuag test

Kev kuaj ntsev ntsev yog ib txoj hauv kev nrov rau kev ntsuas kev ua haujlwm ntawm cov nplaum nyob rau hauv cov xwm txheej zoo li no. Thaum lub sij hawm tus txheej txheem no, cov nplaum yog raug rau cov dej ntsev pos huab nyob rau hauv ib puag ncig tswj rau lub sij hawm. Lub hom phiaj yog simulate cov teebmeem ntawm cov dej ntsev raug, uas yog ib txwm nyob rau hauv ntug hiav txwv dej thiab marine ib puag ncig.

Cov txiaj ntsig ntawm kev ntsuas tshuaj ntsev tuaj yeem pab cov neeg tsim khoom txiav txim siab txog kev xaiv thiab tsim cov khoom nplaum rau lawv daim ntawv thov. Cov txheej txheem kuaj no tseem tuaj yeem kuaj xyuas qhov tsis muaj zog lossis qhov tsis xws ntawm cov nplaum uas yuav cuam tshuam rau nws cov kav ntev thiab ntev.

Muaj ntau txoj hauv kev ntawm kev ntsuas tshuaj ntsev, txhua tus tsim los simulate cov haujlwm sib txawv. Cov txheej txheem no suav nrog kev tshuaj tsuag tas mus li, tshuaj tsuag tsis tu ncua, thiab kev sim cyclic. Cov xwm txheej xeem tuaj yeem sib txawv raws li daim ntawv thov thiab ib puag ncig uas cov nplaum yuav raug fim.

• UV aging test

Adhesives yog ib qho tseem ceeb ntawm ntau yam kev lag luam thiab kev tsim khoom. Txawm li cas los xij, lawv tuaj yeem tawg dhau sijhawm vim raug UV hluav taws xob. Yog li ntawd, nws yog ib qho tseem ceeb rau kev sim lawv cov kev tiv thaiv rau UV aging kom ntseeg tau tias lawv cov kev ua tau zoo ntev -. Muaj ntau ntau txoj hauv kev los kuaj cov nplaum rau UV kev laus, nrog rau txoj hauv kev zoo tshaj plaws yog raug simulated hnub ci nyob rau hauv ib puag ncig tswj.

Thaum lub sijhawm kuaj kev laus ntawm UV txheej txheem, cov nplaum yuav raug UV lub teeb thaum raug saib xyuas rau txhua qhov degradation lossis poob ntawm adhesion. Kev siv thiab wavelength ntawm UV teeb tuaj yeem hloov kho kom simulate ntau theem ntawm UV raug. Cov txheej txheem kuaj no tuaj yeem siv sijhawm nyob qhov twg los ntawm ob peb hnub mus rau ob peb lub lis piam, nyob ntawm seb cov nplaum tshwj xeeb raug kuaj thiab qib ntawm UV raug xav tau.

Muaj ntau hom adhesives nrog txawv formulations, thiab txoj kev kuaj yuav txawv nyob ntawm seb hom nplaum. Piv txwv li, cyanoacrylate adhesives feem ntau raug kuaj nrog lub teeb UV tshwj xeeb, thaum epoxy thiab polyurethane nplaum feem ntau raug kuaj hauv lub tshuab QUV uas simulates hnub ci thiab cua sov.

3. Cov txheej txheem rau Adhesive Test Siv LIB UV Test Chamber

LIB's UV Test Chamber simulates tiag- ntiaj teb ib puag ncig tej yam kev mob, ua kom cov txheej txheem kev laus ntawm cov nplaum nyob rau hauv UV hluav taws xob, kub hloov pauv, thiab av noo. Cov txheej txheem kuaj yog tsim los xyuas kom meej tias cov nplaum tuav lawv lub zog sib txuas, xim ruaj khov, thiab kev ua haujlwm tag nrho thaum lub sijhawm.

Kauj Ruam 1 - Npaj Cov Qauv

Ua ntej, npaj cov qauv nplaum raws li daim ntawv thov tshwj xeeb thiab cov qauv kev cai loj (xws li 75 mm × 150 mm). Rau cov nplaum siv rau qhov chaw, xyuas kom meej tias lawv kis tau zoo sib xws los yog siv rau qhov kev sim ntsuas substrates. Cov qauv yuav tsum tau muab tso rau hauv kev ruaj ntseg ntawm cov qauv tuav kom ntseeg tau tias muaj kev sib raug zoo ntawm UV teeb thaum kuaj.

Kauj Ruam 2 - Teem Cov Ntsuas Ntsuas

Tom ntej no, teeb tsa qhov ntsuas ntsuas raws li cov kev xav tau uas cov nplaum yuav ntsib hauv daim ntawv thov tiag - ntiaj teb. Cov kev teeb tsa rau kev kuaj nplaum yuav muaj xws li:

Irradiance0.35 W / m² ntawm 340 nm

Dub Vaj Huam Sib Luag Kub (BPT)63 ± 3 degree

Chamber KubKub: 50-70 degree

Cov av noo: Ntau dua lossis sib npaug rau 95% RH (nrog rau cov voj voog tshuaj tsuag)

Test Duration: 100-1000 teev (nyob ntawm qhov xav tau ntawm kev laus)

Cov kev txwv no yuav tsum rov ua dua cov kev mob ib puag ncig uas cov nplaum yuav ntsib thaum nws lub neej ua haujlwm.

Kauj ruam 3 - Pib lub voj voog tiv thaiv UV

Ua kom lub voj voog raug UV los ntawm kev xaiv qhov kev pab cuam tsim nyog ntawm LIB UV Test Chamber's PID touchscreen controller. Lub chamber tso cai rau kev hloov pauv ntawm ntau qhov sib txawv, xws li irradiance, kub, thiab cov voj voog tshuaj tsuag, kom simulate tej yam ib puag ncig. Lub voj voog yuav txuas ntxiv mus rau lub sijhawm ua ntej - teem caij xeem.

Kauj Ruam 4 - Moisture/Spray Cycle

Thaum lub sij hawm raug kis, lub chamber lub tshuab txau dej yuav qhib. Lub 10 nozzles nyob rau hauv lub chamber simulate noo noo, los nag, los yog dew raug, accelerating lub aging txheej txheem. Cov dej noo pab simulate kev sib xyaw ntawm UV hluav taws xob thiab cov av noo, uas tuaj yeem ua rau cov nplaum tsis muaj zog lossis tawg dhau sijhawm.

Kauj ruam 5 - Ntsuam xyuas Adhesive Performance

Tom qab lub voj voog ntsuas ua tiav, ua tib zoo tshuaj xyuas cov qauv nplaum rau cov cim qhia ntawm degradation, suav nrog:

Bonding Strength: Xyuas seb cov nplaum puas tau tuav nws lub zog thiab adhesion rau lub substrate. Txhua qhov poob hauv adhesion tuaj yeem qhia tau tias cov nplaum tau ua tsis tiav vim raug UV ntev ntev.

Xim Stability: Ntsuas seb cov xim nplaum los yog cov xim substrate tau faded los yog hloov, qhia tias cov nplaum yog raug rau UV-induced discoloration.

Nto Integrity: Tshawb xyuas cov cim qhia ntawm kev tawg, tev, lossis deterioration ntawm qhov chaw, uas tuaj yeem tshwm sim los ntawm UV raug thiab ya raws kev ya raws.

Tshuaj Stability: Ntsuam xyuas cov nplaum tiv thaiv cov tshuaj lom neeg los ntawm kev tshuaj xyuas nws cov qauv molecular thiab lub cev muaj zog tom qab raug.

Cov ntawv ceeb toom tuaj yeem tsim thiab txheeb xyuas los ntawm USB lossis LAN los muab cov ncauj lus kom ntxaws ntawm cov nplaum nplaum.

Kauj ruam 6 - Txheeb xyuas thiab txhim kho

Raws li cov txiaj ntsig kev xeem, cov tuam txhab tuaj yeem ntsuas qhov ua tau zoo ntawm cov nplaum raws li nws qhov kev tiv thaiv UV aging, kub hloov pauv, thiab ya raws. Yog tias cov nplaum ua tsis tau raws li cov qauv kev ua tau zoo, kev hloov kho rau nws cov qauv yuav tsim nyog. UV Test Chamber muab cov ntaub ntawv tseem ceeb los kho cov nplaum nplaum, ua kom zoo dua qub - lub sijhawm ua haujlwm sab nraum zoov thiab siab - UV ib puag ncig.
