Pokambirana za MDF (Medium Density Fiberboard) za chilengedwe, limodzi mwa mafunso odziwika kwambiri ndi awa: Kodi pali formaldehyde-MDF yaulere kwathunthu?
Yankho n’lakuti ayi.
Ngakhale mitengo yolimba yachilengedwe imatulutsa tinthu tating'ono ta formaldehyde, organic compound yochitika mwachilengedwe. Choncho, lingaliro la "zero formaldehyde" MDF kulibe kwenikweni.
M'malo mwake, miyezo ya chilengedwe imayang'ana kwambiri pakuwongolera kuchuluka kwa mpweya wa formaldehyde mkati mwa malire otetezeka.
Chifukwa chiyani Kutulutsa kwa Formaldehyde Kufunika
Kutulutsa kwa formaldehyde ndikofunikira kwambiri pakuzindikira ngati MDF ndiyoyenera kugwiritsa ntchito m'nyumba, monga:
- Kupanga mipando
- Kukongoletsa mkati
- Makabati ndi ma wardrobes
- Mapanelo a khoma ndi magawo
Kuti zitsimikizire chitetezo, zinthu za MDF ziyenera kukwaniritsa miyezo yotulutsa mpweya yomwe imatanthauzidwa ndi malamulo adziko kapena mayiko.
E1 Standard: Chofunikira Choyambira Kugwiritsa Ntchito M'nyumba
Malinga ndi miyezo yamakono, MDF yogwiritsidwa ntchito m'nyumba iyenera kukwaniritsa kalasi ya E1.
- E1 malire otulutsa: Ochepera kapena ofanana ndi 1.5 mg/L
Ngati bolodi silikukwaniritsa izi, opanga ayenera kugwiritsa ntchito mankhwala owonjezera monga kusindikiza m'mphepete kapena kuthirira pansi kuti achepetse mpweya.
Masiku ano, E1 imatengedwa ngati muyezo wovomerezeka wachilengedwe m'misika yambiri.
Miyezo Yapamwamba Yachilengedwe: E0, CARB P2, ndi F4 Star
Ndi kupita patsogolo kwaukadaulo wopanga, miyezo yolimba yapadziko lonse lapansi yakhazikitsidwa.
E0 Standard
- Pafupifupi. Ochepera kapena ofanana ndi 0.5 mg/L kutulutsa kwa formaldehyde
- Zotsika kwambiri kuposa E1
- Imadziwika kwambiri ngati giredi yapamwamba-yochezeka ndi zachilengedwe
CARB P2 Standard (US)
- Wotsimikizika pansi pa California Air Resources Board
- Amagwiritsa ntchito njira yoyesera yosiyana poyerekeza ndi E0
- Nthawi zambiri amaganiziridwa kuti ndi ofanana ndi mulingo wa E0
F4 Star Standard (Japan)
- Chimodzi mwazinthu zokhwima kwambiri padziko lonse lapansi
- Kutulutsa kwa Formaldehyde Kuchepera kapena kufanana ndi 0.3 mg/L
- Ndiwoyenera-malo apamwamba amkati
Miyezo iyi ndiyofunikira kwambiri m'misika yotumiza kunja, makamaka ku North America, Europe, ndi Japan.
Momwe Mungasankhire Eco-Bodi Yabwino ya MDF
Posankha matabwa a MDF, ogula akuyenera kuyang'ana kwambiri pamtundu wa formaldehyde emission grade m'malo motsatsa malonda.
Nawa malangizo othandiza:
1. Chongani Certification
Ogulitsa odalirika ayenera kupereka ziphaso zovomerezeka monga:
- Satifiketi ya CARB P2
- Malipoti a mayeso a SGS kapena TUV
- Zolemba -zoyendera gulu lachitatu
2. Tsimikizani Zolemba Zamalonda
Ma board ambiri a MDF ali ndi kusindikiza m'mphepete kapena zilembo, kusonyeza:
- Dzina la wopanga
- Gulu lotulutsa (E1, E0, etc.)
3. Match Application Zofunika
- E1: Yoyenera kugwiritsidwa ntchito m'nyumba wamba
- E0 / CARB P2: Yovomerezeka pamipando ndi misika yotumiza kunja
- F4 Star: Ndi yabwino kwa-misika yapamwamba kapena yokhazikika
Global Trends mu MDF Environmental Standards
Pamene kuzindikira kwapadziko lonse za mpweya wabwino m'nyumba kukuchulukirachulukira, kuchuluka kwa -ma board a MDF otulutsa mpweya wochepa kukukulirakulira.
Ogula ndi ogulitsa kunja akuika patsogolo kwambiri:
- Kutsata miyezo yapadziko lonse lapansi
- Chitsimikizo chotsimikizika
- Khalidwe lazinthu lokhazikika
Kwa ogulitsa kunja, kupereka zinthu za MDF zomwe zimakwaniritsa miyezo ya E0 kapena CARB P2 zitha kupititsa patsogolo mpikisano m'misika yapadziko lonse lapansi.
Mapeto
Kumvetsetsa miyezo ya chilengedwe ya MDF ndikofunikira pakusankha chinthu choyenera pamsika wanu ndikugwiritsa ntchito.
Ngakhale kuti E1 ikadali chofunikira kwambiri, miyezo yapamwamba monga E0, CARB P2, ndi F4 Star imapereka magwiridwe antchito abwinoko a chilengedwe komanso kuvomereza kokulirapo kwa msika.
Kusankha MDF yovomerezeka,{0}}yochepa{0}}yotulutsa mpweya wokwanira sikungotsimikizira kuti zinthu zikuyenda bwino komanso zimawonjezera phindu la malonda pazamalonda padziko lonse lapansi.
