Iye zvino vanhu vari kubhadhara zvakanyanya nyaya yehutano, uye "kudya" kunokosha zuva rega rega. Sezvo chirevo chinoti, "chirwere chinobuda mumuromo uye nhamo inobuda mumuromo", uye kudya kune utano kwakagamuchirwa zvikuru nevanhu. Midziyo yekubikira chinhu chakakosha pakubika kwevanhu. Panyaya iyi, nyanzvi dzeWorld Health Organisation dzinokurudzira kushandiswa kwehari dzesimbi. Hari dzesimbi kazhinji hadzina mamwe makemikari zvinhu uye hadzizooxidize. Mukuita kubika nekubika, poto yesimbi haizove nezvinhu zvakanyungudutswa, uye hapana dambudziko rekudonha. Kunyange kana zvinhu zvesimbi zvikanyungudutswa, zvakanakira kutorwa nemunhu. Nyanzvi dzeWHO dzinototenda kuti kubika mupoto ndiyo nzira yakananga yekuwedzera iron. Nhasi tichadzidza nezve ruzivo rwakakosha nezvehari yesimbi.

Chii chinonzi cast iron cookware

Mapoto akagadzirwa nearon-carbon alloys ane kabhoni inodarika 2%. Industrial cast iron kazhinji ine 2% kusvika 4% kabhoni. Carbon iripo muchimiro chegraphite musimbi yakakandwa, uye dzimwe nguva iripo muchimiro chesimenti. Mukuwedzera kune kabhoni, simbi yakakandwa inewo 1% kusvika 3% silicon, pamwe nephosphorus, sulfur nezvimwe zvinhu. Alloy cast iron inewo zvinhu zvakaita senickel, chromium, molybdenum, mhangura, boron, uye vanadium. Carbon nesilicon ndizvo zvinhu zvikuru zvinokanganisa microstructure uye zvivakwa zvesimbi yakakandwa.

Cast iron inogona kukamurwa kuita:

Gray cast iron. Iyo kabhoni yemukati yakakwira (2.7% kusvika 4.0%), iyo kabhoni inonyanya kuvepo muchimiro cheflake graphite, uye iyo yakatsemuka igrey, iyo inonzi grey iron. Nzvimbo yakaderera yakanyungudika (1145-1250), kuderera kudiki panguva yekusimba, kusimba kwesimba uye kuomarara padyo nekabhoni simbi, uye kubatwa kwakanaka kwekuvhunduka. Inoshandiswa kugadzira zvikamu zvezvimiro senge muchina chishandiso mubhedha, silinda uye bhokisi.

White cast iron. Izvo zviri mukati kabhoni nesilicon zvakaderera, kabhoni inonyanya kuvepo muchimiro chesimenti, uye kuputsika ichena chena.

Zvakanakira cast iron cookware

Zvakanakira zvecast iron cookware ndezvekuti kupisa kwekushisa kwakafanana, kupisa kuri pakati nepakati, uye zviri nyore kusanganisa nezvinhu zvine acidic panguva yekubika, izvo zvinowedzera iron yemukati muchikafu kakawanda. Saka sekusimudzira kuvandudzwa kweropa uye kuzadzisa chinangwa chekuzadzazve ropa, yave imwe yemidziyo yekubika yakasarudzika kwezviuru zvemakore. Simbi inowanzoshaikwa mumuviri wemunhu inobva muhari dzesimbi, nekuti hari dzesimbi dzinogona kubatanidza zvinhu zvesimbi pakubika, izvo zviri nyore kuti muviri wemunhu utore.

Mapurofesa ezvekudya kwepasi rose anonongedza kuti mapani esimbi ndiyo midziyo yakachengeteka yekubikira kunze uko. Mapoto esimbi anowanzo gadzirwa nesimbi yenguruve uye kazhinji haana mamwe makemikari. Mukati mekubika nekubika, hapazovi nechinhu chakanyungudutswa muhari yesimbi, uye hapazovi nechinetso chekudonha. Kunyangwe paine iron solute inodonha, zvakanaka kuti muviri wemunhu uibate. Iron poto ine yakanaka yekubatsira mhedzisiro pakudzivirira iron kushomeka anemia. Nekuda kwekuita kwemunyu pasimbi pasi pekushisa kwepamusoro, uye kunyange kupokana pakati pepoto nefoshoro, iyo inorganic iron iri mukati mepamusoro pehari inoderedzwa kuita upfu nedhayamita diki. Mushure mekunge mapoda aya atorwa nemuviri wemunhu, anoshandurwa kuita inorganic iron salts pasi pekuita kwegastric acid, zvoita kuti ave hematopoietic raw materials yemuviri wemunhu uye nekushandisa hunyanzvi hwavo hwekurapa. Iyo iron pot subsidy ndiyo yakanyanya kunanga.

Mukuwedzera, Jennings, munyori wenhau uye nyanzvi yezvokudya mumagazini yeAmerica "Good Eating", akaunzawo mamwe mabhenefiti maviri ekubika muwoki kumuviri wemunhu:

1. Iwe unogona kushandisa mafuta mashoma pakubika mupani yakakandwa yesimbi. Kana iyo pani yesimbi yakakandwa yakashandiswa kwenguva yakareba, mafuta emafuta anozongogadzirwa pamusoro, ayo anonyanya kuenzana nemhedzisiro yepani isina tsvimbo. Usazodze mafuta akawanda paunenge uchibika, kuitira kuti usanyanya kushandisa mafuta ekubikisa. Kuti uchenese pombi yesimbi, hapana detergent inodiwa, ingoshandisa mvura inopisa uye bhurashi rakaoma kuti uchenese, uye uomese zvachose.

2. Pani dzechinyakare dzakakandwa dzesimbi dzinogona kudzivirira zvinogona kuitika zvemakemikari anokuvadza pamusoro pemapani asina tsvimbo. Pani dzisina tsvimbo dzinowanzova necarbon tetrafluoride, kemikari inogona kukuvadza chiropa, kukanganisa kukura, uye inogona kutokonzera gomarara. Pane ongororo zvakare dzinoratidza kuti kemikari iyi inogona kukonzera kuti vanhukadzi vapinde mumwedzi wapera. Paunenge uchibika nepani isina tsvimbo, carbon tetrafluoride ichave yakasvibiswa kuva gasi pane kupisa kwakanyanya, uye ichaputirwa nemuviri wemunhu pamwe chete nehutsi hwekubika. Mukuwedzera, pamusoro pepani isina tsvimbo inoputika nefoshoro, uye carbon tetrafluoride ichawira muzvokudya uye inodyiwa zvakananga nevanhu. Pani dzechinyakare dzesimbi hadzina iyi kemikari yekuputira, uye sezviri pachena hakuna njodzi yakadaro.
