Ibhodwe le-cast iron imbiza yokupheka yendabuko edume kakhulu e-China ngenxa yamandla ayo aphezulu, ukugcwalisa insimbi, umnotho nokusebenza kwayo.Kodwa-ke, amabhodwe ensimbi okusansimbi okwamanje asemakethe wonke ayinsimbi ensimbi noma insimbi egaywe kabusha.Izingxenye eziyinhloko zensimbi ekhonjiwe: i-carbon (C) = 2.0 kuya ku-4.5%, i-silicon (Si) = 1.0 kuya ku-3.0%.Nakuba inezinzuzo zezindleko eziphansi, ukukhishwa okuhle nokusebenza kokusika, kanye nobulukhuni obuphezulu bobuso, yenziwe ngensimbi yengulube Noma iphonswa ngokuqondile ensimbi egaywe kabusha.Ngaphezu kokuqukethwe okuphezulu kwe-silicon nekhabhoni, futhi iqukethe i-phosphorus, isulfure, umthofu, i-cadmium, i-arsenic nezinye izakhi eziyingozi emzimbeni womuntu.Ngakho-ke ekuphekeni, nakuba ibhodwe lensimbi lingengeza i-ayoni, kulula ukudonsa lezi zakhi eziyingozi ngenkathi yengeza i-iron, ikakhulukazi izinsimbi ezisindayo ezifana nomthofu, i-cadmium ne-arsenic zizongena emzimbeni womuntu kanye nokudla futhi zinqwabelene ngokuhamba kwesikhathi.Kuzodala umonakalo omkhulu emzimbeni womuntu.Isibonelo, Izinga Likazwelonke Le-People's Republic of China "Izinga Lenhlanzeko Leziqukathi Zethebula Lensimbi Engagqwali" i-GB9684-88 yenze imithetho yobuningi ezinkombeni ezibonakalayo namakhemikhali e-austenitic stainless steel kanye ne-martensitic stainless steel.Kodwa-ke, ngenxa yokuntuleka kwezindinganiso zikazwelonke noma zezimboni zezinkomba zenhlanzeko ye-iron cookware, kanye nokulinganiselwa kwezindlela zayo zokukhiqiza, bonke abakhiqizi abazange balawule izinkomba zabo zokuhlanzeka.Ngemva kokuhlolwa okungahleliwe, ukukhucululwa kwendle kwezitsha zensimbi, ikakhulukazi izitsha zokupheka zensimbi, emakethe Iningi labo alihlangabezani nezinkomba ezingokomzimba namakhemikhali ensimbi engagqwali.
Kukhona futhi amanye amapani ensimbi agxivizwe ezingcwecweni zensimbi emakethe, nakuba okuqukethwe kwezinsimbi ezisindayo eziyingozi kunganqunywa ngokukhetha izinto zamapuleti ensimbi, ukuze kungabangeli i-typhoid fever emzimbeni womuntu.Kodwa-ke, okuqukethwe kwekhabhoni yepuleti lensimbi ngokuvamile kungaphansi kuka-1.0%, okuholela ebukhuni obuphansi bendawo kanye nokugqwala okulula.Inombolo yesicelo selungelo lobunikazi 90224166.4 iphakamisa ukumboza koqweqwe lwawo lwamandla aphezulu endaweni engaphandle yamapani ensimbi ajwayelekile;izinombolo zesicelo se-patent 87100220 kanye ne-89200759.1 zisebenzisa indlela yokumboza i-aluminium endaweni engaphandle yepani yensimbi ukuxazulula inkinga yokugqwala okungaphezulu, kodwa lezi zindlela zihlukanisa insimbi Izithako zithintana ngqo nokudla, kanye nenzuzo yokuchithwa kwensimbi. epanini lensimbi liyalahleka.
Ngaphezu kwalokho, i-cookware yensimbi eyenziwe ngokugxiviza nokwakhiwa kwepuleti lensimbi inesakhiwo sezinto eziminyene, ngakho izici zayo zokugcina amandla nokugcina ukushisa zimbi kakhulu kunezitsha zokupheka zensimbi;futhi ngenxa yokuthi awekho ama-micropores ngaphezulu, ukumuncwa kwawo uwoyela ongaphezulu kanye nokusebenza kokuwagcina nakho kungcono kunalokhu kwezitsha zokupheka zensimbi.Izitsha zensimbi ezisansimbi ezimpofu.Okokugcina, izitsha zokupheka zensimbi ezenziwe ngokugxiviza nokwakhiwa kwepuleti lensimbi azikwazi ukufeza umphumela wokupheka wezitsha zensimbi ezisansimbi ngenxa yokuthi kunzima ukufeza izimo zokujiya ezingalingani ezinephansi eliwugqinsi nemiphetho emincane esigabeni sawo.
