Mphika wachitsulo wa Cast iron ndiye mphika wodziwika bwino kwambiri ku China chifukwa cha mphamvu zake zambiri, kubwezeretsanso chitsulo, chuma chake komanso kuchita bwino.Komabe, miphika yachitsulo yomwe ili pamsika pano yonse ndi chitsulo choponyedwa kapena chitsulo chobwezerezedwanso.Zigawo zazikulu za chitsulo chosungunuka: carbon (C) = 2.0 mpaka 4.5%, silicon (Si) = 1.0 mpaka 3.0%.Ngakhale kuti ili ndi ubwino wa mtengo wotsika, kutayika kwabwino ndi ntchito yodula, ndi kuuma kwapamwamba pamwamba, kumapangidwa kuchokera ku chitsulo cha nkhumba Kapena kuponyedwa mwachindunji kuchokera kuzitsulo zowonongeka.Kuphatikiza pa silicon yapamwamba komanso kaboni, ilinso ndi phosphorous, sulfure, lead, cadmium, arsenic ndi zinthu zina zovulaza mthupi la munthu.Chifukwa chake pophika, ngakhale mphika wachitsulo ukhoza kuwonjezera chitsulo, ndikosavuta kutulutsa zinthu zovulazazi ndikuwonjezera chitsulo, makamaka zitsulo zolemera monga lead, cadmium ndi arsenic zidzalowa m'thupi la munthu pamodzi ndi chakudya ndikudziunjikira pakapita nthawi.Zidzawononga kwambiri thupi la munthu.Mwachitsanzo, National Standard of the People's Republic of China "Hygienic Standard for Stainless Steel Tableware Containers" GB9684-88 yapanga malamulo ochulukira pama index akuthupi ndi amankhwala a chitsulo chosapanga dzimbiri cha austenitic ndi chitsulo chosapanga dzimbiri cha martensitic.Komabe, chifukwa cha kusowa kwa miyezo ya dziko kapena makampani a zizindikiro zaukhondo za zitsulo zophika, komanso zoperewera za njira zake zopangira, opanga onse sanayang'anire zizindikiro zawo zaukhondo.Pambuyo pofufuza mwachisawawa, ukhondo wa zitsulo zophikira, makamaka zophikira zitsulo, pamsika Ambiri aiwo samakumana ndi zizindikiro zakuthupi ndi zamankhwala zachitsulo chosapanga dzimbiri.
Palinso ziwaya zachitsulo zosindikizidwa kuchokera kuzitsulo zazitsulo pamsika, ngakhale zomwe zili ndi zitsulo zolemera kwambiri zimatha kuchepetsedwa ndi kusankha kwazitsulo zazitsulo, kuti zisapangitse typhoid fever m'thupi la munthu.Komabe, kaboni wa mbale yachitsulo nthawi zambiri imakhala yosakwana 1.0%, zomwe zimapangitsa kuti pakhale kuuma kwapansi komanso dzimbiri mosavuta.Nambala yogwiritsira ntchito patent 90224166.4 ikufuna kuvala enamel yamphamvu kwambiri pamtunda wakunja wazitsulo zachitsulo wamba;ma patent ntchito manambala 87100220 ndi 89200759.1 ntchito njira ❖ kuyanika zitsulo zotayidwa pamwamba pamwamba pa chitsulo poto kuthetsa vuto dzimbiri, koma njira zimenezi kudzipatula chitsulo Zosakaniza ndi kukhudzana mwachindunji ndi chakudya, ndi ubwino chitsulo Kusungunuka. m’chiwaya chachitsulo chatayika.
Kuphatikiza apo, zophikira zachitsulo zopangidwa ndi kupondaponda ndi kupanga mbale zachitsulo zimakhala ndi mawonekedwe ocheperako, kotero mawonekedwe ake osungira mphamvu ndi kuteteza kutentha ndizoipa kuposa zophikira zachitsulo;ndipo chifukwa kulibe ma micropores pamwamba, kuyamwa kwake kwamafuta ndikusunga kwake kulinso kwabwinoko kuposa zophika zachitsulo.Zophika zitsulo zosakanizika bwino.Pomaliza, zophikira zachitsulo zopangidwa ndi kupondaponda ndi kupanga mbale zachitsulo sizingakwaniritse zophikira za zitsulo zotayidwa chifukwa ndizovuta kukwaniritsa mawonekedwe osaneneka okhala ndi pansi wandiweyani komanso m'mbali zoonda mu gawo lake.
