Ib puag ncig kev ua tau zoo ntawm plywood hauv cov tsev ntsuab
Raws li txoj hauv kev zoo los tiv thaiv kev hloov pauv ib puag ncig thoob ntiaj teb thiab cov peev txheej tsis txaus, lub hauv paus tseem ceeb ntawm lub tsev ntsuab yog txhawm rau txo cov kev cuam tshuam ib puag ncig ntawm cov tsev los ntawm kev ua kom zoo dua cov khoom siv hauv tsev thiab tsim kev daws teeb meem.Plywood, raws li cov khoom siv hauv tsev ua los ntawm ntau txheej ntoo, tau siv dav hauv kev tsim kho vim nws cov khoom siv zoo heev thiab cov yam ntxwv ua haujlwm.
- Sustainability ntawm raw khoom
Lub ntsiab raw khoom ntawm plywood yog ntoo, thiab lub hauv paus ntawm nws ib puag ncig kev ua tau zoo nyob rau hauv lub sustainability ntawm raw khoom. Kev tsim cov plywood niaj hnub no feem ntau siv ntoo los ntawm cov ntawv pov thawj kev tswj hwm hav zoov, xws li FSC daim ntawv pov thawj, uas ua kom cov ntoo raug txiav raws li cov qauv kev tiv thaiv ecological thiab kev siv cov peev txheej ruaj khov. FSC-cov ntaub ntawv pov thawj cov ntoo muaj kev tswj hwm ib puag ncig thiab kev lav phib xaub ntawm kev sib raug zoo, tiv thaiv kev txiav ntoo tsis raug cai thiab kev sau qoob loo ntau dhau, thiab tiv thaiv cov peev txheej hav zoov thoob ntiaj teb thiab biodiversity.
- Cov txheej txheem tsim khoom thiab kev cuam tshuam ib puag ncig
Cov txheej txheem ntawm cov plywood suav nrog kev txiav, ziab, gluing thiab lwm cov kauj ruam ntawm cov ntoo, uas cov nplaum siv hauv cov txheej txheem tsim khoom muaj qhov cuam tshuam loj rau kev ua haujlwm ib puag ncig. Cov nplaum nplaum muaj xws li phenolic resins thiab urea formaldehyde resins, uas tuaj yeem tso tawm cov organic sib txuas (VOCs). Vim li no, ntau lub tuam txhab plywood tau ua cov kauj ruam los siv cov nplaum ib puag ncig nrog cov ntsiab lus VOCs tsawg. Tsis tas li ntawd, cov khoom pov tseg thiab cov khoom siv los ntawm cov txheej txheem tsim khoom, xws li ntoo chips thiab txiav scraps, tuaj yeem rov ua dua tshiab kom txo tau lub nra ntawm ib puag ncig. Kev tsim cov plywood niaj hnub no nyiam ua cov txheej txheem ib puag ncig zoo dua qub, txo kev cuam tshuam ib puag ncig thiab txhim kho kev ua haujlwm tau zoo.
- Txoj kev pov tseg thiab kev cuam tshuam ib puag ncig
Thaum kawg ntawm kev pab cuam lub neej ntawm plywood, nws cov khoom pov tseg yog qhov txuas tseem ceeb hauv kev tiv thaiv ib puag ncig. Cov txheej txheem pov tseg ib txwm muaj xws li incineration thiab landfill, ob qho tib si muaj kev txhawj xeeb txog ib puag ncig. Thaum plywood yog incinerated, cov pa phem xws li dioxins tuaj yeem raug tso tawm, uas tuaj yeem cuam tshuam loj rau huab cua zoo thiab ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv. Tsis tas li ntawd, kub kub combustion thaum lub sij hawm incineration kuj tseem tso tawm ntau cov pa roj carbon dioxide, exacerbating lub tsev cog khoom nyhuv. Kev cog qoob loo plywood siv cov khoom siv av muaj txiaj ntsig thiab tuaj yeem ua rau muaj kev sib kis ntawm cov av thiab dej hauv av. Adhesives thiab tshuaj additives nyob rau hauv plywood tuaj yeem nkag mus rau hauv av thaum lub sij hawm landfilling, ua rau lub sij hawm ntev ntawm cov av thiab dej. Cov txheej txheem pov tseg cov tsoos no tsis yog tsuas yog ua rau lub nra hnyav rau ib puag ncig, tab sis kuj tsis ua raws li cov kev cai ib puag ncig ntawm cov vaj tsev ntsuab. Txhawm rau txo cov kev cuam tshuam tsis zoo no, nws yog qhov yuav tsum tau tshawb nrhiav ntau txoj hauv kev kho tus phooj ywg ib puag ncig, xws li kev kho cov peev txheej thiab rov siv dua, thiab txhawb kev txhim kho kev lag luam pov tseg.
Cov ntsiab lus
Kev siv ntawmPlywoodnyob rau hauv cov vaj tsev ntsuab tau pom cov txiaj ntsig tseem ceeb ntawm ib puag ncig, suav nrog kev siv cov khoom siv qis, qis zog xav tau, thiab kev cuam tshuam ib puag ncig qis. Txawm li cas los xij, kev siv cov nplaum thiab pov tseg hauv cov txheej txheem tsim khoom tseem yuav tsum tau txhim kho ntxiv kom ua tau raws li qhov yuav tsum tau ua ntawm cov vaj tsev ntsuab. Nyob rau hauv lub neej yav tom ntej, ib puag ncig kev ua tau zoo ntawm plywood yuav txuas ntxiv txhim kho nrog kev txhim kho cov txheej txheem ntau lawm thiab kev tsim cov tshuab pov tseg pov tseg.
