Kukurumidza kukura kwesimba rinodiwa nepasi rose kwakagadzira nzira yekuvandudzwa kwezvimwe zviwanikwa zvezviwanikwa.Zvisinei, marasha achiri kuita basa rakakosha mutsime guru renyika.Marasha akaverengera 29% yesimba repasi rose muna 2015, uye inofungidzirwa kuti. kuti panosvika 2035, marasha acharamba achizvidavirira 24% yesimba.Sezvo maindasitiri ne-chigadzirwa chemarasha anopfuta magetsi, huwandu hwemarasha anobhururuka madota acharamba akakwira kwenguva yakareba.Madota emarashaChave chinonyanya kutariswa nezvezvakatipoteredza nekuda kwekuumbwa kwayo kwakaoma uye nekusabatwa zvakanaka. Panguva imwe cheteyo, marasha enhunzi inogona kushandiswa, inoda kushandiswa nekuchimbidza. Parizvino, kushandiswa kwemadota enhunzi yemarasha kunosanganisira zvakawanda. siyana yeminda,asi iyo yakakwirira-value utilization mwero wakadzikira.Chikonzero chekushandiswa kwepamusoro-soro ndechekuongorora maitiro emarasha nhunzi yemarasha.Marasha enhunzi yemarasha anoumbwa neakasimba kana maburi amorphous spherical particles,irregular unburned carbon particles and mineral. zvidimbu zvakaita semullite,quartz,hematite,etc.Pane zvimwe zvakasiyana muchimiro chemuviri,chemical composition uye mineral composition yemarasha fly ash munzvimbo dzakasiyana dzinogadzira.Mashandisiro ayo uye chinangwa chayo zvakare hazvina kufanana.Kuumbwa kwakaoma kwefonzi yemarasha madota ndicho chipingamupinyi chikuru chekushandiswa kwepamusoro-kukosha.Zvisinei, zvinhu zvinobatsira, senge hollow microspheres, unburned carbon,magnetic materials,etccan kupatsanurwa kubva kuzvinhu zvakaoma kunzwisisa nemaitiro ekuparadzanisa.Makemikari uye mineral content yenhunzi ash yakaderera. -priced raw materials for high value-added products like geopolymers,glass-ceramics and zeolites.Makemikari ekugadzirwa uye yepakutanga particle size yemarasha fly ash ine simba guru pakusimba kwe geopolymers.The optimal technical conditions inofanira kutsanangurwa pa Zvichienderana nemakemikari emarasha enhunzi yemarasha, girazi-ceramics yakagadzirwa kubva kumadota ekubhururuka kwemarasha inonyanya kuumbwa nemaitiro maviri: CaO-Al2O3-SiO2 uye MgO-Al2O3- SiO2, asi kushandiswa kwesimba kwenzira yekugadzirira yakanyanyisa.Iyo nzira yekuisa sintering ine simba shoma rinoshandiswa richiri kuda kuenderera mberi nekudzidza uye kuparidzirwa.Kune zvakawanda zvekushandiswa kwekushandiswa kwezeolite yakagadzirwa kubva kumarasha anobhururuka, asi maitiro mashomanana emaindasitiri anotakurwa. out.The theoretical research pamusoro pegadziriro yemesoporous silica and silica aerosol experiments haina kunyatsokwana,mamiriro acho akaoma kudzora, uye pachine nzira refu pamberi pekugadzirwa kwemaindasitiri.
