Vim tias formaldehyde-based-basede cov nplaum feem ntau siv nyob rau hauv cov txheej txheem kev noj qab haus huv, nws yuav cuam tshuam rau tib neeg txoj kev txwv, nws yuav cuam tshuam cov txheej txheem pub dawb, nws yuav cuam tshuam cov txheej txheem pub dawb, nws yuav cuam tshuam cov txheej txheem pub dawb, nws yuav cuam tshuam cov txheej txheem pub dawb, nws yuav cuam tshuam cov txheej txheem pub dawb, nws yuav cuam tshuam cov txheej txheem pub dawb, nws yuav cuam tshuam cov txheej txheem pub dawb, nws yuav cuam tshuam cov txheej txheem pub dawb, nws yuav cuam tshuam cov txheej txheem pub dawb, nws yuav cuam tshuam cov txheej txheem pub dawb, nws yuav cuam tshuam cov txheej txheem pub dawb, nws yuav cuam tshuam cov txheej txheem pub dawb, nws yuav cuam tshuam rau kev txwv tsis pub dhau los lossis cov txheej txheem dawb tshaj tawm, nws yuav cuam tshuam cov txheej txheem pub dawb, nws yuav cuam tshuam rau cov txheej txheem pub dawb, nws yuav cuam tshuam rau cov kev txwv tsis pub dhau los lossis cov txheej txheem kev ua tiav pub dawb, nws yuav cuam tshuam rau cov kev txwv tsis pub dhau los lossis cov txheej txheem dawb tshaj tawm, nws yuav cuam tshuam cov txheej txheem pub dawb ntau dua lossis tsis muaj kev cuam tshuam rau cov neeg blockboard raws li kev . ua ntej, tso cov qhov rooj tsis zoo, thiab muab tso rau hauv chav blockboard yog tsawg, thiab kev siv yuav tsis cuam tshuam rau tib neeg kev noj qab haus huv; Yog tias qhov tsis hnov tsw yog lub suab quaj muag, nws txhais tau tias qhov kev tawm dag zog ntawm cov blockboard yuav siab {}}
Rau qhov teeb meem tsis txaus ntseeg ntawm cov blockboard, lub polecular txheej txheem ntawm frystalhyde, thiab nws tau teem rau hauv cov muaj zog sab hauv yog li 0} 0.4 thiab 0.62 nanometers, thiab lawv txhua tus polarculents, uas muaj cov yam ntxwv zoo nkauj, Benzene, yog li ua kom tiav cov txiaj ntsig ntawm huab cua sab hauv. Nws tuaj yeem adsorb thiab decompose formaldehyde, thiab nws tuaj yeem rov qab siv dua tom qab lub hnub kis tau.
