Mkhalidwe wa Kafukufuku ndi Kupita Patsogolo kwa Kugwiritsa Ntchito Phulusa la Malasha Lofunika Kwambiri

Kuwonjezeka kwachangu kwa kufunikira kwa mphamvu padziko lonse kwatsegula njira yopangira njira zina zachilengedwe. Komabe, malasha akadali ndi gawo lofunika kwambiri pa gwero lalikulu la mphamvu padziko lonse lapansi. Malasha adapanga 29% ya mphamvu yapadziko lonse mu 2015, ndipo akuti pofika chaka cha 2035, malasha adzapangabe 24% ya mphamvu. Monga chinthu chochokera ku mafakitale opangira magetsi opangidwa ndi malasha, kuchuluka kwa phulusa la ntchentche za malasha kudzakhalabe kwakukulu kwa nthawi yayitali.Phulusa la ntchentche ya malasha Chakhala chinthu chachikulu chomwe chikukhudza kwambiri zachilengedwe chifukwa cha kapangidwe kake kovuta komanso kusamalidwa bwino. Nthawi yomweyo, phulusa la malasha ndi chinthu chomwe chikufunika kugwiritsidwa ntchito mwachangu. Pakadali pano, kugwiritsa ntchito phulusa la malasha kumakhudza madera osiyanasiyana, koma kuchuluka kwa kugwiritsidwa ntchito kwake ndi kochepa. Cholinga chachikulu cha kugwiritsa ntchito phulusa la malasha ndikuphunzira za mawonekedwe a phulusa la malasha. Phulusa la malasha limapangidwa ndi tinthu tolimba kapena topanda kanthu tozungulira, tinthu ta kaboni tosapsa komanso tinthu ta mchere monga mullite, quartz, hematite, ndi zina zotero. Pali kusiyana kwina pa mawonekedwe enieni, kapangidwe ka mankhwala ndi kapangidwe ka mchere ka phulusa la malasha m'malo osiyanasiyana opangira zinthu. Njira yogwiritsira ntchito ndi cholinga chake sizifanana. Kapangidwe ka phulusa la malasha ndi cholepheretsa chachikulu pakugwiritsa ntchito phulusa la mtengo wapatali. Komabe, zinthu zothandiza, monga ma microspheres opanda kanthu, kaboni wosapsa, zinthu zamaginito, ndi zina zotero zimatha kulekanitsidwa ndi zinthu zovuta pogwiritsa ntchito njira zolekanitsira zoyenera. Kapangidwe ka mankhwala ndi kapangidwe ka mchere ka phulusa la malasha ndi zinthu zotsika mtengo zopangira zinthu zopindulitsa kwambiri monga geopolymers, magalasi-ceramics ndi Ma zeolite. Kapangidwe ka mankhwala ndi kukula kwa tinthu toyambirira ta phulusa la malasha zimakhudza kwambiri mphamvu ya ma geopolymer. Mikhalidwe yabwino kwambiri yaukadaulo iyenera kutsimikiziridwa poganizira mokwanira za makhalidwe oyambira a phulusa la malasha pokonzekera ma geopolymer. Malinga ndi kapangidwe ka mankhwala a phulusa la malasha, magalasi-ceramics opangidwa kuchokera ku phulusa la malasha makamaka amakhala ndi machitidwe awiri: CaO-Al2O3-SiO2 ndi MgO-Al2O3-SiO2, koma kugwiritsa ntchito mphamvu kwa njira yokonzekera ndi kwakukulu. Njira yothira mwachindunji yokhala ndi mphamvu zochepa ikufunikabe kuphunziridwa kwambiri ndikutchuka. Pali mayeso ambiri ogwiritsira ntchito zeolite opangidwa kuchokera ku phulusa la malasha, koma mayeso ochepa a mafakitale amachitika. Kafukufuku wamalingaliro pakukonzekera mayeso a mesoporous silica ndi silica aerosol siwokwanira mokwanira, mikhalidwe ndi yovuta kuyilamulira, ndipo padakali njira yayitali kuti mafakitale apange.
