Ukuchazwa kweshidi lensimbi elishisayo eligoqiwe
Ishidi lensimbi elivuthayo elinensimbi elinephethini eliphakanyisiwe ebusweni. Iphethini ephakanyisiwe ingabulwa njengoRhombus, ubhontshisi noma ipea. Akukho hlobo olulodwa kuphela lwephethini ephepheni lensimbi elihloliwe, kodwa futhi nenkimbinkimbi yezinhlobo ezimbili noma ezingaphezu kwezimbili zamaphethini wephethini elilodwa lensimbi ekhethiwe. Futhi kungabizwa ngokuthi i-grid yensimbi yensimbi.
Ukwakheka kwamakhemikhali kweshidi lensimbi elishisayo elivuthiwe
Ishidi lethu lensimbi elivuthayo elishisayo livame ukugingqa ngensimbi evamile ye-Carlbon. Inani lokuqukethwe kwekhabhoni lingafinyelela ngaphezu kwe-0,06%, 0.09% noma 0.10%, inani eliphezulu lingu-0.22%. Inani lokuqukethwe kwe-silicon lisuka ku-0.12-0.30%, inani lokuqukethwe kweMaNansese lisuka ku-0.25-0.65%, kanye nenani lokuqukethwe le-phosphorus kanye nenani lokuqukethwe se-phosphorus livame ngaphansi kuka-0.045%.
Ishidi lensimbi elishisayo elishisayo linayo izinzuzo ezahlukahlukene, njengobuhle ngokubukeka, yeqa ukumelana nokusindisa impahla yensimbi, ukuze ihlole ishidi lensimbi noma ikhwalithi yokuphakanyiswa kwephethini okushisayo ngokuyinhloko.

Ukusetshenziswa kwepuleti yensimbi eshisayo evuthayo
Ishidi lensimbi elishisiwe elishisayo livame ukusetshenziselwa embonini yokwakha umkhumbi, i-boiler, imoto, ugandaganda, isakhiwo sesitimela kanye nokwakhiwa kwezakhiwo. Kumininingwane, kunezidingo eziningi zeshidi lensimbi elishisayo eligoqiwe ukwenza ishidi lensimbi elishisayo lenze indawo yokusebenzela, endaweni yokusebenzela, i-Fiserf Frame Pedal, i-Ship Deck nokunye.
Iphakheji kanye nokulethwa kwepuleti lensimbi eshisayo egoqiwe
Izinto ezizokulungela ukupakisha zifaka phakathi: umucu wensimbi omncane, ibhande lensimbi le-crude noma i-angle yensimbi, iphepha lobuciko noma iphepha lobuciko noma ishidi elenziwe nge-gallvanized.
Ipuleti lensimbi elishisayo elishisiwe kufanele lisongwe ngephepha lobuciko noma ishidi elenziwe nge-gallvanized ngaphandle, futhi kufanele lihlanganiswe ngentambo yensimbi emincane, umucu wensimbi amathathu noma amabili emigqeni emincane emincane, neminye imichilo emithathu noma emibili eqondisweni eguqukayo. Ngaphezu kwalokho, ukuze kulungiswe ishidi lensimbi elishisayo eligoqiwe futhi ugweme umucu onqenqemeni uzophulwa, ibhande lensimbi elicwengekile lisikiwe ngaphansi kwesikwele sensimbi emaphethelweni. Vele, ishidi lensimbi elivuthayo elishisayo libe lihlanganiswe ngaphandle kwephepha lobuciko noma ishidi elenziwe ngogalvanized. Kuya ngesidingo sekhasimende.
Uma kubhekwa izinto zokuhamba ezisuka egangeni ukulayisha ethekwini, iloli lizosetshenziswa kaningi. Futhi ubungako obukhulu beloli ngalinye ngu-40 Mt.
