Thaum cov xim, plastics, textiles, thiab cov khoom siv kos duab raug tshav ntuj, xim fading thiab degradation degradation yog qhov yuav tsum tau zam. Txawm li cas los xij, kev ntsuam xyuas sab nraum zoov feem ntau siv ntau lub hlis lossis ntau xyoo, thiab cov txiaj ntsig sib txawv nrog huab cua, caij nyoog thiab cheeb tsam. Lub Teeb Kev Ntsuas Lub Teeb Ceev nrawm nrawm cov txheej txheem no los ntawm kev tsim lub hnub ci tiag tiag, qhov kub thiab av noo nyob hauv chav tswj hwm, ua kom cov ntaub ntawv ntsuas kev ntseeg siab hauv lub lis piam hloov xyoo.
LIBLub Teeb Fastness Test Instrument yog engineered rau qhov tseeb xim fading ntsuam xyuas nyob rau hauv xenon -arc los yog UV irradiation. Nws simulates lub zog spectral faib ntawm ntuj nruab hnub nrig, thaum ntsuas xim tuav, gloss lwj, tawg, chalking, thiab laus teb nrog tag nrho ua raws li ASTM G155, ASTM D6695, ISO 11341, ISO 105, ISO 4892-2, D7869 & IEC.
1. Lub Teeb Fastness Test Instrument ntsuas dab tsi?
A Lub Teeb Fastness Test Instrumentyog tsim los ntsuam xyuas cov ntaub ntawv zoo li cas xws li textiles, plastics, coatings, prints, tawv, dyes, thiab pigmentskhaws cov xim thiab kev ncaj ncees ntawm lub cev thaum raug tshav ntuj los yog UV hluav taws xob. Qhov kev ntsuas no tseem ceeb heev vim tias lub hnub ci -tshwj xeeb tshaj yog UV wavelengths ntawm300-400 nm- tuaj yeem ua raucov tshuaj tiv thaiv photochemical, ua rau pigment fading, polymer saw degradation, nto chalking, thiab gloss txo.
Thaum lub sij hawm kuaj, cov qauv yuav raug tswj irradiation, kub, thiab av noo tej yam kev mob rau simulatelub hlis los yog xyoo ntawm kev laus sab nraum zoov nyob rau hauv ib lub sij hawm luv luv. Los ntawm kev sib piv ua ntej- thiab tom qab- cov txiaj ntsig tau tshwm sim, cov kws tshawb fawb tau txais kev nkag siab txog cov khoom siv lub teeb -induced durability.
Cov kev ntsuas ntsuas ib txwm muaj xws li:
- xim txawvtxhawm rau txheeb xyuas cov qib fading
- Gloss retention lossis gloss poob tus nqi
- Yellowing index hloovrau dawb los yog lub teeb - cov ntaub ntawv xim
- Deg cracking, chalking, los yog hmoov degree
- Tensile zog poob los yog brittleness nce
- Cov tsos mob hloov xws li discoloration, dullness, thiab kev ntxhib los mos degradation
Qhov kev xeem pab manufacturers:
Sib piv lightfastness kev ua tau zoo ntawm cov pigments sib txawv los yog formulations
Validate cov khoom zoo ua ntej loj ntau lawm los yog ua lag luam tso tawm
Txheeb xyuas lub neej kev pab sab nraum zoov, huab cua, thiab ntev - ruaj khov
Optimize UV stabilizers, tiv thaiv - daj additives, thiab tiv thaiv txheej
Lub teeb ceev ceev tau muab faib ua cov qauv siv xws li ISO Blue Wool Scale, feem ntau muab qhab nia los ntawm Qib 1 (tsis zoo heev) txog qib 8 (zoo heev). Rau cov txheej txheem kev lag luam thiab cov khoom siv tsheb, cov qauv uas tswj cov xim sib txawv < 1.7 tom qab 96 teev ntawm xenon arc raug feem ntau suav hais tias siab -kev ua tau zoo, ua kom pom kev tiv thaiv fading thiab yees duab- laus.

4. FAQs ntawm lub teeb ceev ceev ntsuas ntsuas
1. xenon teeb yog cov roj tso pa tawm. Cov roj tso tawm roj teeb yog dab tsi? Lawv txoj cai yog dab tsi?
Gas discharge teeb yog lub teeb pom kev zoo uas emits lub teeb siv lub hauv paus ntsiab lus ntawm cov pa tawm. Nyob rau hauv lub kaw chamber ntawm kev tswj siab, qhov hluav taws xob yog siv ntawm electrodes los ionize cov pa. Qhov no ua rau siab -kub plasma, ua kom pom lub teeb pom kev.
2. Lub xenon teeb raj muaj quartz puab txheej thiab borosilicate txheej lim. Qhov no puas txhais tau tias cov phab ntsa sab hauv yog quartz thiab sab nrauv phab ntsa yog borosilicate? Yuav ua li cas "filter" to taub ntawm no?
Cov pa tawm arc muaj nyob rau hauv lub raj quartz kom tiv taus qhov kub thiab txias. Sab nrauv borosilicate txheej ua haujlwm raws li kev kho qhov muaglim, uas tswj spectrum kis tau tus mob kom phim cov qauv xeem. Nws tsis yog lub teeb nws tus kheej, tab sis ib qho kev lim dej sab nraud tsim los tsim cov teeb pom kev zoo rau 280-800 nm rau kev sim ua raws.
3. Lub teeb lub raj muaj lub neej ntev ntawm 1600 teev. Puas muaj txoj hauv kev txuas ntxiv mus?
1600 teev yog tus qauv xenon teeb lifespan. Thaum nws tuaj yeem ua haujlwm ntev dua, irradiance maj mam txo qis, cuam tshuam rau qhov ntsuas qhov tseeb. Txhawm rau tswj xyuas qhov tseeb, kev hloov pauv yog pom zoo thaum ntsuas cov teev mus txog.
4. Dab tsi yog qhov siab tshaj plaws qauv thickness rau tus qauv rotating xenon teeb khib? Yuav ua li cas rau customized racks?
Standard rotating racks txhawb nqa3 cm ibqauv thickness. Kev cai racks tuaj yeem ncav cuagmus txog 11 cm, haum rau cov qauv loj lossis cov qauv tsim.
5. Yog hais tias lub xeem chamber tsis tau loaded tag nrho thiab muaj qhov khoob, nws puas yuav cuam tshuam cov av noo nyob rau hauv?
Tsis yog. Txawm tias muaj qhov chaw khoob, cov av noo tsis sib xws tseem nyob ruaj khov ua tsaug rau cov cua hauv nruab nrab thiab cov tshuab ua kom muaj kev sib txig sib luag.
