Ntawv khob tiv thaiv
Sis tsis ncaj zoo uas lub khob rau hauv lub lag luam, thiab qeeg. Tej manufacturers ntawv thiaj li yuav ua rau cov iav tawv dawb ntau, txuas rau fluorescent brightening tus neeg saib xyuas, cov fluorescent siv tshuaj uas ua rau hlwb mus mutate, ib zaug nyob rau hauv lub cev yuav yog ib tug neeg mob uas yuav muab yam. Yuav ua ntawv khob mus txog hla dej nyhuv, ntau lawm nyob rau hauv li phab ntsa coated ib txheej polyethylene hla dej zaj duab xis, polyethylene yog cov zaub mov nyob hauv kev ruaj ntseg feem ntau cov khoom siv tshuaj ntxuav, tiam sis yog xaiv yuav tej khoom siv ua phem, los yog ua kev tsis clearance, hauv polyethylene kub yaj los pleev rau txheej txheem khob ntawv nyob tus, ntuj yuav oxidation rau lub Carbonyl tebchaw , thiab carbonyl tebchaw nyob sov Xia yooj yim neeg tsis mloog hais, tab sis nyob ntawv khob hliv Shi kub, saum ntuj tawm nrov heev nthe, ces tus neeg yuav tsis hnov tsw ntxhiab tsw. Txawm tias txoj kev tshawb no tsis muaj qhov yuav paub tseeb uas hauv khob ntawv ntawm Carbonyl tebchaw txiav txim yuav tus mob rau hauv tib neeg lub cev, tab sis ntawm lub ziag no, ntev ntxiv no organic compound yuav tsum muaj teeb meem rau tus neeg lub cev. Worrying ntau heev tshaj dua yog tias tej tsis zoo ntawv khob uas siv cov polyethylene, reprocessing txheej txheem yuav ua cracking, ua ntau yam teeb meem tebchaw siv yog cov yuav los mus rau hauv dej. Txwv los ntawm lub xeev siv polyethylene siv nyob rau hauv cov zaub mov ntim, tab sis vim yog pheej yig polyethylene siv, tej me factories thiaj li yuav txuag nqi, yuav tseem txhaum kev cai.
