Environmental kev ua tau zoo ntawm particle board

Nyob rau hauv cov txheej txheem ntawm particle board, formaldehyde-raws li adhesives feem ntau yog siv, yog li cov khoom tiav yuav tso tawm ntau dua los yog tsawg dua dawb formaldehyde. Thaum cov ntsiab lus pub dawb formaldehyde dhau ib qho kev txwv, nws yuav cuam tshuam rau tib neeg kev noj qab haus huv. Txheeb xyuas cov formaldehyde emission ntawm particleboard yog ib txoj kev nyuaj, thiab formaldehyde emission ntawm particleboard tsuas yog txiav txim siab ua ntej los ntawm txoj kev hauv qab no. Ua ntej, ntim cov khoom siv tsis siv cov khoom siv hauv ib chav me me, kaw lub qhov rooj thiab qhov rais, thiab nkag mus rau hauv chav rau kev soj ntsuam tom qab lub sijhawm khaws cia. Yog tias tsis muaj ntxhiab tsw ntxhiab, nws txhais tau hais tias formaldehyde tso tawm tus nqi ntawm cov blockboard tsawg, thiab kev siv yuav tsis cuam tshuam rau tib neeg kev noj qab haus huv; Yog hais tias tus ntxhiab tsw loj los yog muaj kev xav ntawm tearing, formaldehyde tso tawm tus nqi ntawm cov particle board yuav siab dua.

Nyob rau hauv kev pom ntawm formaldehyde teeb meem ntawm particle board, txoj kev zoo tshaj plaws los tshem tawm formaldehyde tam sim no yog siv Maya xiav, uas yog ib qho adsorbent raws li attapulgite thiab sepiolite, los ntawm kev ntxiv lwm yam minerals xws li diatomaceous ntiaj teb thiab tourmaline. Tsim los ntawm kev siv technology tshwj xeeb, lub pore txoj kab uas hla ntawm lub pores sab hauv yog nyob nruab nrab ntawm {{0}}.27 thiab 0.98 nanometers nyob rau hauv ib tug crystal arrangement. Nyob rau tib lub sijhawm, nws muaj hluav taws xob tsis muaj zog. Lub cheeb molecular ntawm formaldehyde, ammonia, benzene, toluene, thiab xylene yog tag nrho ntawm 0.4 thiab 0.62 nanometers, thiab lawv yog tag nrho cov polar molecules. Lawv muaj cov yam ntxwv ntawm kev nyiam adsorbing cov pa phem xws li formaldehyde, benzene, TVOC, thiab lwm yam., kom ua tiav kev ua kom huv ntawm huab cua sab hauv. Nws tuaj yeem nqus tau thiab decompose formaldehyde, thiab tuaj yeem rov qab siv tau tom qab hnub raug tshav.
