ISigaba esihlanganisiweyo sitshintsha iTekhnoloji yokuGcinwa koBushushuukuphepha ukusilela okuninzi kokugcinwa kobushushu obunengqiqo kunye nesigaba sokutshintsha iindlela zokugcina ubushushu ngokudibanisa zombini iindlela. Le teknoloji iye yaba yindawo yophando kwiminyaka yakutshanje, ngaphakathi nangaphandle. Nangona kunjalo, izixhobo zesiqhelo zesikhafu ezisetyenziswa kobu buchwepheshe zizimbiwa zendalo okanye iimveliso zazo zesibini. Ukukhutshwa okukhulu okanye ukusetyenzwa kwezi mathiriyeli kunokonakalisa inkqubo yendalo yasekuhlaleni kwaye kutye izixa ezibalulekileyo zamandla efosili. Ukuthomalalisa ezi mpembelelo zokusingqongileyo, inkunkuma eqinileyo ingasetyenziselwa ukuvelisa izinto eziyintlanganisela yokutshintsha ubushushu.
I-Carbide slag, inkunkuma eqinileyo kwimizi-mveliso eyenziwe ngexesha lokuveliswa kwe-acetylene kunye ne-polyvinyl chloride, idlula iitoni zezigidi ezingama-50 ngonyaka e-China. Ukusetyenziswa kwangoku kwe-carbide slag kushishino lwesamente kuye kwafikelela kwi-saturation, ekhokelela ekuqokeleleni okukhulu okuvulekileyo, ukukhutshwa komhlaba, kunye nokulahlwa kolwandle, okonakalisa kakhulu i-ecosystem yendawo. Kukho imfuneko engxamisekileyo yokukhangela iindlela ezintsha zokusetyenziswa kobutyebi.
Ukujongana nokusetyenziswa okukhulu kwenkunkuma ye-carbide slag kunye nokulungiselela i-carbon ephantsi, ixabiso eliphantsi le-composite yesigaba sokutshintsha izinto zokugcina ukushisa, abaphandi abavela kwiYunivesithi yaseBeijing yezoBunjineli boLuntu kunye ne-Architecture bacetywayo ukusebenzisa i-carbide slag njengento ye-scaffold. Basebenzisa indlela yokucofa okubandayo yokucofa ukuze balungiselele i-Na₂CO₃/carbide slag composite isigaba sokutshintsha izinto zokugcina ubushushu, ngokulandela amanyathelo aboniswe kumzobo. Iisampulu zezixhobo zokutshintsha izigaba ezisixhenxe ezinemilinganiselo eyahlukeneyo (NC5-NC7) zalungiswa. Uthathela ingqalelo uguquko olupheleleyo, ukuvuza kwetyuwa enyibilikisiweyo kumphezulu, kunye noxinano lokugcina ubushushu, nangona ugcino lobushushu besampulu ye-NC4 yayiyeyona iphakamileyo phakathi kwezinto ezintathu eziyintlanganisela, ibonise uguquko oluncinci kunye nokuvuza. Ke ngoko, isampula ye-NC5 izimisele ukuba nomlinganiselo ofanelekileyo wobunzima kwisigaba esidibeneyo sokutshintsha izinto zokugcina ubushushu. Iqela emva koko lihlalutye i-macroscopic morphology, ukusebenza kokugcinwa kobushushu, iipropathi zomatshini, i-microscopic morphology, ukuzinza kwe-cyclic, kunye nokuhambelana kwecandelo lesigaba esihlanganisiweyo sokutshintsha izinto zokugcina ubushushu, zinika ezi zigqibo zilandelayo:
01Ukuhambelana phakathi kwe-carbide slag kunye ne-Na₂CO₃ ilungile, ivumela i-carbide slag ukuba ithathe indawo yezinto zendalo ze-scaffold zendalo ekuhlanganiseni i-Na₂CO₃/carbide slag isigaba esihlanganisiweyo sokutshintsha izinto zokugcina ubushushu. Oku kuququzelela i-recycling ye-recycling enkulu ye-carbide slag kwaye ifezekisa i-carbon ephantsi, ukulungiswa kweendleko eziphantsi kwesigaba esidibeneyo sokutshintsha izinto zokugcina ukushisa.
02Isigaba esihlanganisiweyo sitshintsha izinto zokugcina ubushushu kunye nokusebenza okugqwesileyo kunokulungiswa kunye neqhekeza elikhulu le-52.5% ye-carbide slag kunye ne-47.5% yokutshintsha izinto eziphathekayo (Na₂CO₃). Izinto eziphathekayo azibonakalisi i-deformation okanye ukuvuza, kunye nokugcinwa kokushisa kokushisa ukuya kwi-993 J / g kwiqondo lokushisa kwe-100-900 ° C, amandla oxinzelelo lwe-22.02 MPa, kunye ne-thermal conductivity ye-0.62 W / (m•K ). Emva kokujikeleza kwe-100 yokufudumeza / ukupholisa, ukusebenza kokugcinwa kobushushu kwesampuli ye-NC5 kwahlala kuzinzile.
03Ubukhulu besigaba sokutshintsha kwezinto ezibonakalayo zefilimu phakathi kweengqungquthela ze-scaffold zigqiba amandla okunxibelelana phakathi kweengqungquthela zezinto eziphathekayo kunye namandla oxinzelelo lwesigaba esidibeneyo sokutshintsha izinto zokugcina ubushushu. Isigaba esihlanganisiweyo sitshintsha izinto zokugcinwa kobushushu ezilungiselelwe kunye neyona nxalenye iphezulu yobunzima bokutshintsha izinto zesigaba sibonisa ezona mpawu zibalaseleyo zoomatshini.
04I-thermal conductivity ye-scaffold material particles iyona nto iphambili echaphazela ukusebenza kokutshintshwa kobushushu besigaba esidibeneyo sokutshintsha izinto zokugcina ukushisa. Ukungeniswa kunye nokubhengezwa kwezinto zokutshintsha kwesigaba kwisakhiwo se-pore se-scaffold material particles kuphucula i-thermal conductivity ye-scaffold material particles, ngaloo ndlela kuphuculwe ukusebenza kokutshintshwa kobushushu besigaba esidibeneyo sokutshintsha izinto zokugcina ukushisa.
