Ngoku abantu bahlawula ingqalelo ngakumbi nangakumbi kwisihloko sempilo, kwaye "ukutya" kubalulekile yonke imihla. Njengoko intetho isithi, "isifo siphuma emlonyeni kwaye ilishwa liphuma emlonyeni", kwaye ukutya okunempilo kuye kwafumana ingqalelo enkulu ebantwini. Izitya zokupheka zisisixhobo esiyimfuneko ekuphekeni kwabantu. Kule nkalo, iingcali ezivela kwi-World Health Organization zincoma ukusetyenziswa kweembiza zetsimbi. Iimbiza ze-iron azinazo ezinye iikhemikhali kwaye aziyi kukhupha i-oxidize. Kwinkqubo yokupheka nokupheka, imbiza yentsimbi ayiyi kuba nezinto ezinyibilikayo, kwaye akukho ngxaki yokuwa. Nokuba izinto zentsimbi ziyanyibilika, ilungile ekufunxeni komntu. Iingcali ze-WHO zide zikholelwe ukuba ukupheka kwimbiza yentsimbi yeyona ndlela ingqalileyo yokongeza i-iron. Namhlanje siza kufunda malunga nolwazi olufanelekileyo malunga nembiza yentsimbi.

Yintoni i-cookware yentsimbi

Iimbiza ezenziwe nge-iron-carbon alloys kunye nomxholo wekhabhoni ongaphezu kwe-2%. I-iron cast ye-industrial iqulethe i-2% ukuya kwi-4% yekhabhoni. Ikhabhoni ikhona ikwimo yegraphite kwintsimbi etyhidiweyo, kwaye ngamanye amaxesha ikhona ikwimo yesamente. Ukongeza kwikhabhoni, isinyithi esityhidiweyo sine-1% ukuya kwi-3% ye-silicon, kunye ne-phosphorus, isulfure kunye nezinye izinto. I-alloy cast iron iqulethe izinto ezifana ne-nickel, i-chromium, i-molybdenum, ubhedu, i-boron kunye ne-vanadium. Ikhabhoni kunye ne-silicon zizinto eziphambili ezichaphazela i-microstructure kunye neempawu zentsimbi.

Intsimbi yentsimbi inokohlulwa ibe:

Intsimbi engwevu. Umxholo wekhabhoni uphezulu (2.7% ukuya kwi-4.0%), i-carbon ikakhulu ikhona kwifom ye-flake graphite, kwaye i-fracture i-gray, ebizwa ngokuba yintsimbi engwevu. Indawo encibilikayo ephantsi (i-1145-1250), i-shrinkage encinci ngexesha lokuqiniswa, amandla okunyamezela kunye nobunzima obusondeleyo kwintsimbi ye-carbon, kunye nokufunxa okulungileyo. Isetyenziselwa ukwenza iinxalenye zesakhiwo ezifana nebhedi yesixhobo somatshini, isilinda kunye nebhokisi.

Intsimbi emhlophe. Umxholo wekhabhoni kunye ne-silicon iphantsi, i-carbon ikakhulu ikhona ngendlela ye-cementite, kwaye i-fracture i-silvery white.

Izibonelelo ze-cookware yentsimbi

Iinzuzo ze-cookware ye-iron cast kukuba ukufudumeza ubushushu bulingana, ubushushu buphakathi, kwaye kulula ukudibanisa kunye nezinto ezinomuncu ngexesha lokupheka, okwandisa umxholo wesinyithi ekudleni amaxesha amaninzi. Ukuze kukhuthazwe ukuvuselelwa kwegazi kunye nokufezekisa injongo yokuzalisa igazi, ibe yenye yezixhobo zokupheka ezikhethiweyo ngamawaka eminyaka. Intsimbi edla ngokuswela emzimbeni womntu ivela kwiimbiza zetsimbi, kuba iimbiza zentsimbi zinokufaka izinto zentsimbi xa ziphekwa, nto leyo ilungele ukuba umzimba womntu ufunxe.

Iinjingalwazi zezondlo zehlabathi zibonisa ukuba iipani zentsimbi zezona zixhobo zasekhitshini ezikhuselekileyo. Iimbiza zentsimbi zenziwe ngentsimbi yehagu kwaye aziqulathanga ezinye iikhemikhali. Kwinkqubo yokupheka nokupheka, akuyi kubakho nto inyibilikayo kwisitya sentsimbi, kwaye akuyi kubakho ngxaki yokuwa. Nokuba kukho i- iron solute ephumayo, kuhle ukuba umzimba womntu uyifunxe. I-iron pot inefuthe elihle elincedisayo ekuthinteleni i-anemia yokusilela kwesinyithi. Ngenxa yefuthe letyuwa kwintsimbi phantsi kobushushu obuphezulu, kunye nokungqubana phakathi kwembiza kunye nefotsholo, intsimbi engaphiliyo kwindawo engaphakathi embizeni ihlatywa ibe ngumgubo ngobubanzi obuncinci. Emva kokuba ezi powders zifunxwe ngumzimba womntu, ziguqulwa zibe ziityuwa zentsimbi ye-inorganic phantsi kwesenzo se-asidi ye-gastric, ngaloo ndlela ibe yimathiriyeli ye-hematopoietic ekrwada yomzimba womntu kwaye isebenzise impembelelo yabo yonyango. Inkxaso yembiza yentsimbi yeyona ithe ngqo.

Ukongeza, uJennings, umbhali wemihlathi kunye nesondlo kwiphephancwadi laseMelika elithi "Good Eating", wazisa nezinye izibonelelo ezimbini zokupheka kwi-wok emzimbeni womntu:

1. Ungasebenzisa ioli encinci ekuphekeni kwipani yentsimbi. Ukuba i-pan yentsimbi ephosiweyo isetyenziselwa ixesha elide, i-oyile ye-oyile iya kubumba ngokwemvelo phezu kwendawo, eyona nto ilingana nomphumo we-pan non-stick. Musa ukubeka ioli eninzi xa upheka, ukuze uphephe ukusebenzisa ioli yokupheka kakhulu. Ukucoca imbiza yentsimbi, akukho nto yokucoca efunekayo, sebenzisa nje amanzi atshisayo kunye nebrashi enzima ukuyicoca, kwaye uyomise ngokupheleleyo.

2. Iipaneli zentsimbi eziqhelekileyo zinokuphepha iimpembelelo ezinokuthi zibe neekhemikhali ezinobungozi kumphezulu weepani ezingezizo. Iipani zokuqhotsa ezingaqhotyokiyo zihlala zinekhabhon tetrafluoride, imichiza enokwenzakalisa isibindi, ichaphazele ukukhula, kwaye inokubangela nomhlaza. Kukwakho nezifundo ezibonisa ukuba le khemikhali inokubangela ukuba abasetyhini bangene exesheni kwangoko. Xa upheka nge-pan-non-stick pan, i-carbon tetrafluoride iya kuhlanjululwa kwi-gas kwiqondo lokushisa eliphezulu, kwaye iya kufakwa ngumzimba womntu kunye ne-fumes yokupheka. Ukongezelela, umphezulu we-pan-non-stick pan utyhulwa ngefosholo, kwaye i-carbon tetrafluoride iya kuwela ekudleni kwaye idliwe ngokuthe ngqo ngabantu. Iipani zentsimbi zemveli azinayo le khemikhali yokugquma, kwaye ngokwemvelo ayikho ingozi enjalo.
