Lub neej ntev ntawm daim npav qhia cov av noo feem ntau yog 2-5 xyoos, nyob ntawm qhov chaw cia, siv zaus, ib puag ncig ruaj khov, thiab hom khoom (cobalt-muaj lossis cobalt-dawb). Raws li kev khaws cia thiab siv tau zoo, qee qhov siab - daim npav tsis muaj cobalt tsis muaj av noo zoo tuaj yeem ua haujlwm ruaj khov rau ntau dua 5 xyoos.
Tej yam tseem ceeb cuam tshuam rau lub neej
Cia ib puag ncig: Cov ntawv qhia cov av noo yuav tsum muab khaws cia rau hauv lub thawv ntim rau hauv qhov chaw qhuav, txias, tsis txhob tshav ntuj ncaj qha thiab kub thiab av noo. Cov ntim khoom qub feem ntau siv cov kaus poom hlau lossis lub tshuab nqus tsev- kaw cov dej noo- cov hnab pov thawj nrog ua - hauv cov desiccants. Kev qhib ntau zaus lossis tsis ua haujlwm los hloov lub tshuab desiccant yuav ua rau lub neej luv luv.
Exposure Frequency thiab Duration: Txhua qhov qhib nthuav tawm daim npav mus rau huab cua, ua rau dej ntawm cov dej noo-sensing khoom. Nquag lossis ncua sij hawm raug (xws li, tshaj 30 feeb) ua kom cov khoom laus, txo cov xim rhiab heev thiab raug.
Xim Hloov Cycles: Txawm hais tias cov ntawv teev cov av noo txhawb cov xim hloov pauv, rov ua dua "xiav → liab → xiav" lub voj voog tuaj yeem ua rau qaug zog tshuaj lom neeg. Nws feem ntau pom zoo kom ua tiav cov xim - hloov lub voj voog ntawm ib daim npav tsuas yog 50 zaug kom muaj kev ntseeg tau ntawm kev nyeem ntawv.
Kev kis kab mob thiab kev puas tsuaj rau lub cev: Tes tawm hws, roj, plua plav, lossis cov tee dej tuaj yeem kis cov ntsiab lus qhia, ua rau muaj kev ua haujlwm tsis zoo lossis kev txiav txim tsis raug. Kev puas tsuaj rau lub cev xws li folding lossis khawb kuj tuaj yeem cuam tshuam rau kev txiav txim siab; Kev sib cuag ncaj qha nrog cov chaw rhiab heev yuav tsum zam.
Yam khoom sib txawv
Cobalt-muaj hom (cobalt chloride): Tus nqi qis, hloov xim pom tseeb, tab sis EU tau muab cais ua pawg 2 carcinogen (2004/73/EC), txwv tsis pub siv hauv cov khoom xa tawm. Kev siv sijhawm ntev - ua rau muaj kev pheej hmoo ntawm kev ua raws cai.
Cobalt- hom dawb: Siv cov ntaub ntawv zoo ib puag ncig (xws li cov organic dyes lossis hlau complexes), ua raws li RoHS, REACH, thiab lwm yam kev cai ib puag ncig, muaj kev nyab xeeb thiab ruaj khov zoo dua, thiab raug pom zoo raws li qhov kev xaiv.
