Kev ntsuam xyuas kev ntseeg tau yog cov haujlwm uas tau ua los ntsuas qhov kev ntseeg tau ntawm cov khoom siv thaum lub sijhawm nws lub neej teev nyob rau hauv txhua qhov xwm txheej xws li kev npaj siv, thauj, lossis khaws cia. Kev ntsuam xyuas kev ntseeg tau ntau yog kev kuaj kev laus, kev ntsuas ntsev ntsev, ntsuas kub thiab qis, ntsuas kua ua kua thiab lwm yam plaub yam tseem ceeb.
Niaj hnub no peb hais tias qhov kev ntsuam xyuas kev laus, hauv cov ntsiab lus nrov, yog muab cov khoom tso rau hauv lub thawv kev laus rau lub sijhawm kom pom cov kev hloov pauv uas tshwm sim ua ntej thiab tom qab kev laus ntawm cov khoom. Kev kuaj kev laus tshaj plaws yog UV aging (Cov khoom tsim nyog:UV aging test chamber), xenon teeb aging, ozone aging, kub cua laus. Cov khoom lag luam uas yuav tsum tau kuaj xyuas kev laus yog cov roj hmab, yas, cov nplaum thiab lwm yam khoom siv polymer, nrog rau cov coatings, hlau thiab lwm yam khoom.
UV aging VS Xenon teeb kev laus
Ob qho tib si UV aging thiab xenon teeb aging yog simulated kev sim ua los ntawm lub aging chamber uas simulates tshav ntuj. Qhov txawv li cas? Cia peb piav luv luv.
Ultraviolet aging simulates hnub ci los yog khoom siv lub teeb ci, feem ntau yog xav txog lub peev xwm ntawm cov khoom los tiv thaiv lub teeb ultraviolet. Feem ntau rau cov khoom siv tsis yog xim hlau, UV aging lub thawv yog siv 8 UV fluorescent teeb nrog lub zog ntsuas ntawm 40W ua lub teeb ci.
xenon teeb aging yog siv xenon arc teeb uas tuaj yeem simulate tag nrho lub hnub ci spectrum los tsim cov teeb pom kev puas tsuaj uas muaj nyob hauv ntau qhov chaw. Piv nrog rau kev laus ultraviolet, tib yam yog simulated tshav ntuj, tab sis nws qhia ntau dua ntawm peb lo lus "tag nrho cov hnub ci", vim tias nws tuaj yeem tsim lub teeb ultraviolet, pom lub teeb, lub teeb infrared. Nyob rau hauv ib lo lus, lub xenon teeb aging lub thawv yog simulate tshav ntuj, thiab lub ultraviolet laus lub thawv yog ntau dua los xyaum ua tej yam ua rau lub hnub ci.

Ozone aging VS Kub huab cua laus
Ozone aging, raws li lub npe qhia, yog pom lub peev xwm ntawm cov khoom los tiv thaiv ozone. Cov huab cua kub aging yog pom kev tiv thaiv kev laus muaj peev xwm ntawm cov khoom nyob rau hauv ib puag ncig huab cua kub.
Raws li ib txwm muaj, qhov kev ntsuam xyuas kev laus feem ntau yog rau cov khoom siv tsis yog xim hlau, xws li roj hmab yas, feem ntau ua rau xenon teeb aging thiab kub huab cua aging. Coatings feem ntau yuav tsum tau ua xenon teeb aging, ib co coatings siv nyob rau hauv seaside ib puag ncig tej zaum yuav tau ua ultraviolet laus, cov khoom nplaum feem ntau ua rau huab cua kub laus.
