1. Ndi chiyaniPepala mwala?
Pepala lamwala limapangidwa ndi michere yamiyala yamiyala yokhala ndi michere yayikulu komanso kugawa kwakukulu monga momwe zinthu zimakhalira ndi 70-80%) ndi polym yothandiza (zomwe zili 20-30%). Pogwiritsa ntchito mfundo za urlyment ya ulycofu ndi mawonekedwe a kusintha kwa polymer, pepala la miyala limapangidwa ndi polymer potuluka ndikuwombera ukadaulo pambuyo pokonza mwapadera. Zinthu zopanga zamwala zimalemba zomwezo ndi kusindikiza monga pepala lazitsamba. Nthawi yomweyo, ili ndi chipadera cha phukusi la pulasitiki.
2. Mawonekedwe ofunikira a pepala lamwala?
Matayala a miyala kuphatikizapo chitetezo, chathupi, ndi zina, komanso mawonekedwe akulu ndi madzi, kupewa matenda osokoneza bongo.
Kusindikiza kwamiyala sikudzakhazikika ndi tanthauzo lenileni, kulondola kwa 2880dpi, pamwamba pa filimuyi, sikungakhale ndi mankhwala ndi inki, yomwe idzapewa mtundu wa inki kapena decolorization phenomenon.
3. Chifukwa chiyani timasankha pepala lamiyala?
a. Ntchito zopangira. Pepala lachikhalidwe kuti anyeke nkhuni zambiri, ndipo pepala lamwala ndi zinthu zambiri zam'migodi zochulukirapo padziko lapansi ngati zida zazikulu, pafupifupi 80%, kupanga polruthylene (PE) pafupifupi 20%. Ngati konzani zotulutsa zamiyala yapachaka ya 5400kt M3, 84 miliyoni m3 ikhoza kupulumutsidwa chaka chilichonse, kuphatikiza kudula mitengo kwa makilomita 1010. Malinga ndi momwe amamwa mankhwala amadzi amamwa cha 200t papepala, kutulutsa pachaka kwa matani 5.4 miliyoni a matani a miyala 1.08 miliyoni chaka chilichonse.
b. Ubwino Wachilengedwe. Njira zonse zopanga zamwala sizifunikira madzi, poyerekeza ndi mapepala azikhalidwe zomwe zimatulutsa, kuchapa ndi njira zina zopangira mafakitale opanga mafakitale. Nthawi yomweyo, pepala lobwezeretsedwanso limatumizidwa ku infineration kuti lisapangidwe, lomwe silikutulutsa utsi wakuda, ndipo mchere wotsalira umabwezeretsedwanso padziko lapansi ndi zachilengedwe.
Mapepala opanga miyala amasunga zothandizira nkhalango ndi zinthu zamadzi, ndipo zogwiritsidwa ntchito ndi mphamvu ndi 2/3 zokha za pepala lolemba.
