Insimbi kwabantu, izakhiwo zalo

Ukusebenzisa iron man linomlando omude. Metal imikhando eqonda ngokwanele kakhulu. Okuqukethwe yensimbi e koqweqwe singamaphesenti angu 4.1, okungukuthi, kule ipharamitha kuba owesibili phakathi izinsimbi kanye wesine phakathi kwazo zonke izakhi. Ngakho-ke akukho lutho isimanga yokuthi ngisho ngaphambi kwesikhathi sethu esivamile (II ekhulwini) wathola indlela ukukhiqizwa yayo futhi kucutshungulwe. Esikhathini esizayo, ubuchwepheshe ethuthukisiwe, luvula izindlela ezintsha zokuthola izinsuku esikhiqiza yensimbi, futhi kancane kancane kwensimbi seyibe umholi in ukwenziwa izimpahla.

Inani yensimbi akugcini emkhakheni zokukhiqiza impahla. Kunjengoba isici trace kuyingxenye-hemoglobin - umbala obomvu igazi lethu ngenxa yokubakhona yensimbi kuwo. Iron ibaluleke kakhulu ekukhuleni kwesihlahla evamile nokuthuthuka zezitshalo, ke ohilelekile oxidative izinqubo kanye liyingxenye protoplasm.

Noma yini esaluketshezi, kuhlanganise yensimbi, has izici zayo siqu. Uma izikali ukubeka eyodwa kilogram lokhu okusansimbi eyodwa kilogram ka Lint, isisindo bayoba okufanayo, kuphela ivolumu ngesikhathi esifanayo ngeke hlala ongenakuqhathaniswa ngokuphelele. Into wukuthi kwabantu yensimbi itsatfwa obukhulu kunobukaJohane fluff. Ngaphansi kwabantu ukuqonda mass equkethwe emqulwini iyunithi. impahla ngayinye has kwabantu lalo. Ngo amanzi, isibonelo, ayinkulungwane amakhilogremu / imitha cubic, kusukela ice - ayisishiyagalolunye amakhilogremu / imitha cubic.

Lokhu kubizwa ngokusentshenziswa kwabantu uyaca kuya ehlasela ivolumu isilinganiso. Ngezinye kwabantu kuthonywa izici eziningana. Ngakho, incike lokushisa. izinto abaningi ubuhlobo ezilandelayo: uma izinga lokushisa lehla ukwanda kwabantu nge okwandayo - ngincipha. Nokho, lokhu abuse okumbalwa, futhi omunye wabo - amanzi. Lapha, kwenzeka okuphambene lapho izinga lokushisa lehla kwabantu bayo incipha.

Ngenxa okuhlukile enjalo emhlabeni ukuphila. Ice ulula kunokotini amanzi, futhi isekelwe esikweni lasendulo impela phezu. Uma bekungenjalo, ngabe wawisa phansi, walala khona futhi akazange ancibilike. Futhi zonke izilwandle nasolwandle ngabe yiqhwa ngokuphelele isikhathi. It kuvela ukuthi umqondo we ndaba ukuminyana kuholela isiphetho esithakazelisayo kakhulu mayelana nokwenzeka lwezinto eziphilayo emhlabeni.

ixhomeke kwabantu ukwakheka kwamakhemikhali ketshezi. umphumela Ubukhulu kwabantu yensimbi abe Silicon ne-carbon. Bona ukwehlisa ukuminyana elihlanzekile yensimbi ingxenye 7800 amakhilogremu / imitha cubic at Igumbi lokushisa. Ngesikhathi esifanayo, le-carbon okuqukethwe izakhiwo engaphansi yensimbi. Empeleni, insimbi esetshenziswa Alloys, ikakhulukazi nge-carbon - ezihlukahlukene steel bese waphonsa yensimbi.

yensimbi Sakaza ngokuvamile iqukethe kuka 2.14 amaphesenti carbon, okuqukethwe carbon steel - ephansi (0.8-1%). kwabantu yensimbi kulezi zimo zizohluka. I okuqinile cast iron lunesibalo ka 7000-7200 kg / imitha cubic ashisa okwejwayelekile, le steel ngaphansi kwezimo ezifanayo lunesibalo ka 7500-7600 kg / imitha cubic. Ngakho-ke, ngo-kwabantu phakathi steel kakhulu okusansimbi nensimbi.

Ngokusho izici zayo yensimbi ulula: uma kuyo ukuze hit inqamuka. Lezinsimbi ezivezwa kabusha zensimbi eziyisisekelo-mpilo esithandweni. Njengoba liyancipha ukucutshungulwa carbon okuqukethwe, kuthiwa adliwe. Ngokusho impahla yayo ihluke kakhulu kwethi lensimbi. Kungaba kokuzihlanganisa, iphuma okwenza. izakhiwo engeziwe we steel ozuza sibonga izithasiselo ukunika izici oyifunayo - amandla, ukushintsha-shintsha, ubulukhuni.

Esikhathini okunikezwe into ezifana kwabantu yensimbi. Izici ezithile izinto ukuminyana ushintsho ngaphansi kwezimo ezihlukahlukene zangaphandle. Kubuyekezwe izakhiwo ozikhethile yensimbi nalokho okukushoyo ekukhiqizeni izinto futhi isici trace emzimbeni.
