1. Ndi chiyaniStone Paper?
Mapepala a miyala amapangidwa ndi miyala yamchere yamchere yokhala ndi nkhokwe zazikulu komanso kugawa kwakukulu monga zopangira zazikulu (calcium carbonate zili 70-80%) ndi polima ngati zinthu zothandizira (zomwe zili ndi 20-30%). Pogwiritsa ntchito mfundo ya polima mawonekedwe umagwirira ndi makhalidwe a polima kusinthidwa, pepala miyala amapangidwa ndi polima extrusion ndi kuwomba luso pambuyo processing wapadera. Zida zamapepala amiyala zimakhala ndi ntchito yolemba yofananira komanso kusindikiza ngati pepala la fiber. Pa nthawi yomweyi, ili ndi zida zoyambira zamapulasitiki.
2. Zinthu zazikuluzikulu za pepala lamwala?
Mapepala a miyala yamwala kuphatikizapo chitetezo, thupi, ndi zina, ndi mbali zazikulu ndizopanda madzi, zimateteza nkhungu, zimateteza mafuta, tizilombo, ndi zina zotero, komanso pazinthu zakuthupi kukana kung'amba, kukana kupukuta kuli bwino kuposa pepala lamatabwa.
Kusindikiza kwa pepala la mwala sikudzakhazikitsidwa ndi tanthauzo lapamwamba, mpaka 2880DPI kulondola, pamwamba sikukuphimbidwa ndi filimu, sikudzakhala ndi mankhwala ndi inki, zomwe zingapewe kutayika kwa mtundu kapena kutayika kwamtundu.
3. N’chifukwa chiyani timasankha mapepala amwala?
a. Yaiwisi chuma phindu. Traditional pepala kudya kwambiri nkhuni, ndi miyala pepala ndi wochuluka kwambiri mchere chuma padziko kutumphuka kashiamu carbonate monga chuma chachikulu, za 80%, polima zakuthupi - petrochemical kupanga polyethylene (PE) pafupifupi 20%. Ngati mukukonzekera kutulutsa kwapachaka kwa pepala lamwala la 5400kt, nkhuni za 8.64 miliyoni za m3 zitha kupulumutsidwa chaka chilichonse, zomwe zimafanana ndi kuchepetsa kuwononga nkhalango ma kilomita 1010. Malinga ndi ndondomeko yachikhalidwe ya kumwa madzi a 200t pa tani ya pepala, kutulutsa kwapachaka kwa matani 5.4 miliyoni a polojekiti yamapepala a miyala kungapulumutse matani 1.08 miliyoni a madzi chaka chilichonse.
b. Ubwino wa chilengedwe. Ntchito yonse yopanga mapepala amiyala sifunikira madzi, poyerekeza ndi kupanga mapepala komwe kumachotsa kuphika, kutsuka, kuthira mafuta ndi njira zina zoipitsa, kuthetsa zinyalala zamakampani opanga mapepala. Pa nthawi yomweyo, zobwezerezedwanso mwala pepala amatumizidwa ku incinerator incineration, amene si kutulutsa utsi wakuda, ndi otsala inorganic mchere ufa akhoza kubwerera ku dziko lapansi ndi chilengedwe.
Kupanga mapepala a miyala kumapulumutsa kwambiri nkhalango ndi madzi, ndipo mphamvu yogwiritsira ntchito mphamvu ndi 2/3 yokha ya njira zopangira mapepala.
