I-Induction Heating Ferroconcrete Dismantling Machine
Indlela yokushisa yokungeniswa kwe-high-frequency induction isekelwe esimisweni sokuthi ukhonkolo ozungeze i-rebar uba
sengozini njengoba ukushisa okukhiqizwa endaweni ye-rebar kudluliselwa kukhonkolo. Ngale ndlela, ukushisa kwenzeka
ngaphakathi kukakhonkolo ngaphandle kokuxhumana okuqondile nento evuthayo, okungukuthi i-rebar yangaphakathi. Njengoba kuboniswe kuMfanekiso 3, kunjalo
kungenzeka ukushisisa ngokushesha i-rebar yangaphakathi ngaphakathi kwe-ferroconcrete ngoba ukuminyana kwamandla kuphezulu kakhulu kule ndlela uma kuqhathaniswa nezindlela zokushisisa i-ohmic nezindlela zokushisisa ama-microwave ngokusekelwe ekushiseni.
Kukhonkolo, ijeli ye-calcium silicate hydrate (CSH) yenza i-60-70% ye-hydrate ye-cement, ne-Ca (OH)2 ifinyelela ku-20-30%. Ngokuvamile, amanzi amahhala kuma-capillary tube pores ayahwamuka cishe ku-100°C, futhi ijeli iyawa njengesigaba sokuqala sokuphelelwa amanzi emzimbeni ku-180°C. I-Ca(OH)2 ibola ku-450–550°C, bese i-CSH ibola ngaphezu kuka-700°C. Njengoba i-matrix yekhonkrithi iyisakhiwo esinama-pore amaningi esihlanganisa i-hydrate ye-cement kanye namanzi amuncwa futhi ahlanganiswe namanzi e-capillary tube, amanzi ejeli namanzi amahhala futhi ahlanganise, ukungcola okukhonkolo endaweni yokushisa okuphezulu, okuholela ekushintsheni kwesakhiwo se-pore kanye nezinguquko zamakhemikhali. Lokhu kube nomthelela ezicini ezibonakalayo zikakhonkolo, okuncike ezinhlotsheni zikasimende, ingxube, neqoqo elisetshenzisiwe. Amandla acindezelwe kakhonkolo avame ukwehla kakhulu ngaphezu kuka-500°C nakuba engabonakali kakhulu
ishintsha ifike ku-200°C [9, 10].
I-conductivity yokushisa kakhonkolo iyahlukahluka kuye ngezinga lengxube, ukuminyana, imvelo yama-aggregates, isimo somswakama kanye nohlobo lukasimende. Ngokuvamile, kwaziwa ukuthi ukushisa kwekhonkrithi kungu-2.5-3.0 kcal / mh ° C, futhi ukushisa ukushisa ekushiseni okuphezulu kuvame ukwehla njengoba izinga lokushisa likhuphuka. I-Harmathy ibike ukuthi umswakama ukhuphule ukushisa kokhonkolo ngaphansi kwe-100℃ [11], kodwa u-Schneider ubike ukuthi ngokuvamile ukushisa kokushisa kwehla kancane kancane kuzo zonke izigaba zokushisa njengoba izinga lokushisa langaphakathi likakhonkolo likhuphuka [9]….
