Ukukhula ngesivinini kwesidingo samandla emhlabeni wonke sekuvule indlela yokuthuthukiswa kwezinye izindlela zemithombo yemvelo.Nokho, amalahle asadlala indima ebalulekile emthonjeni wamandla omkhulu emhlabeni.Amalahle abalelwa ku-29% wokuphakelwa kwamandla omhlaba ngo-2015, futhi kulinganiselwa ukuthi ukuthi ngo-2035, amalahle azobe esangu-24% wamandla. Njengomkhiqizo wezimboni wezimboni zamandla kagesi ngamalahle, inani lomlotha wamalahle lizohlala liphezulu isikhathi eside.Umlotha wempukane yamalahlesekuyiyona nto okugxilwe kuyo kakhulu kwezemvelo ngenxa yokwakheka kwayo okuyinkimbinkimbi kanye nokwelashwa okungenangqondo. Ngesikhathi esifanayo, umlotha wamalahle uyisisetshenziswa esingaba khona, esidinga ukusetshenziswa ngokushesha ngendlela enengqondo. uhla lwezinkambu, kodwa izinga lokusebenzisa inani eliphezulu liphansi.Isisekelo sokusetshenziswa kwenani eliphezulu ukufunda izakhiwo zempukane yamalahle. Umlotha wempukane yamalahle wakhiwe izinhlayiya eziyindilinga eziqinile noma ezingenalutho ze-amorphous, izinhlayiya zekhabhoni ezingashi ezingavamile kanye namaminerali. izinhlayiya ezifana ne-mullite, i-quartz, i-hematite, njll.Kunomehluko othile ezintweni ezibonakalayo, ukwakheka kwamakhemikhali kanye nokwakheka kwamaminerali omlotha wempukane yamalahle ezindaweni ezikhiqizayo ezihlukene. Indlela yokusetshenziswa nenjongo yawo nakho akufani.Ukwakheka okuyinkimbinkimbi kwempukane yamalahle Umlotha uyisithiyo esikhulu ekusetshenzisweni kwenani eliphezulu.Nokho, izakhi eziwusizo, njengama-microspheres angenalutho,ikhabhoni engashi,izinto ezizibuthe,etccan zihlukaniswa nezingxenye eziyinkimbinkimbi ngamasu okuhlukanisa anengqondo.Ukwakheka kwamakhemikhali kanye nokwakheka kwamaminerali omlotha wempukane kuphansi -impahla yokusetshenziswa enenani eliphezulu yemikhiqizo enenani eliphakeme efana ne-geopolymers, glass-ceramics kanye nama-zeolite. Ukwakheka kwamakhemikhali kanye nosayizi wangempela wezinhlayiyana zomlotha wamalahle kunomthelela omkhulu emandleni ama-geopolymers. Izimo zobuchwepheshe ezifanele kufanele zinqunywe isisekelo sokucabangela ngokugcwele izici eziyisisekelo zomlotha wempukane yamalahle lapho ulungiselela ama-geopolymers.Ngokokwakheka kwamakhemikhali omlotha wempukane yamalahle, ingilazi-ceramics elungiswe ngomlotha wempukane yamalahle ikakhulukazi iqukethe izinhlelo ezimbili:CaO-Al2O3-SiO2 kanye neMgO-Al2O3- I-SiO2, kodwa ukusetshenziswa kwamandla kwendlela yokulungiselela kuphezulu uma kuqhathaniswa.Indlela ye-sintering eqondile esebenzisa amandla aphansi isadinga ukuqhutshekwa kufundwe futhi yaziwe.Kunezilingo eziningi zokusetshenziswa ze-zeolite ezenziwe ngomlotha wempukane yamalahle, kodwa kumbalwa ukuhlola kwezimboni okwenziwayo. out.Ucwaningo lwethiyori ekulungiseleleni ukuhlolwa kwe-mesoporous silica kanye ne-silica aerosol akuphelele ngokwanele, izimo kunzima ukuzilawula, futhi kusenendlela ende ngaphambi kokukhiqizwa kwezimboni.
