Iingqayi kunye neemagi kuyo yonke indawo ebonwayo namhlanje, intsimbi engatyiwa kunye neglasi yeyona ixhaphakileyo, kodwa uyazi kumaxesha akudala, yintoni itumbler eyenziwe ngayo?
Iimagi zokuqala zibuyela kwi-Neolithic Stone Age yangaphambili kwaye zenziwe ngethambo kwaye zingenazo izibambo.Iimagi ezindala ekurhanelwa ukuba zivela kweli xesha nazo zenziwe ngamaplanga, kodwa iimagi zomthi zibonakalise ukuba zinzima kakhulu ukuzigcina.Emva kophuhliso lwewaka leminyaka, abantu ngokuthe ngcembe benza isitya ngokusebenzisa udongwe okanye isinyithi, yaqala nini impucuko yanamhlanje.
Intsimbi engatyiwayo liqela lealloyi ezinentsimbi equlethe ubuncinci obumalunga ne-11% yechromium, [4]: 3 [5] ukwakheka okuthintela intsimbi ekuruseni kwaye ikwabonelela ngeempawu ezimelana nobushushu.[4]: 3 [5] [6] [7] [8] Iindidi ezahlukeneyo zensimbi engenasici ziquka izinto zekhabhoni (ukusuka kwi-0.03% ukuya kwi-1.00%), i-nitrogen, i-aluminium, i-silicon, isulfure, i-titanium, i-nickel, ithusi, i-selenium, i-niobium, kunye ne-molybdenum. [4]: 3 Iindidi ezikhethekileyo zensimbi engenasici zihlala zichongwa ngenombolo yazo ye-AISI enamanani amathathu, umzekelo, i-304 engenasici.Umgangatho we-ISO 15510 udwelisa ukubunjwa kweekhemikhali zeentsimbi ezingenasici kwiinkcukacha kwimigangatho ekhoyo ye-ISO, ASTM, EN, JIS, kunye ne-GB (isiTshayina) kwitheyibhile yokutshintshana eluncedo.– Isishwankathelo seWikipedia
Akunakwenzeka ukuba ezinye izinto zetsimbi, ezinzima, ixabiso eliphezulu kwaye lingazinzile (ipropathi yeekhemikhali), indebe yensimbi engenasici inomsebenzi weendleko, ezinzile kunye nokhuseleko.Isetyenziswa ngokubanzi kwi-drinksware, ezonyango, kwilabhoratri njl.njl. Ingqina ukuba imakethi yamkele intsimbi engatyiwayo njengoko ibukeka intle kwaye icocekile-lula.Isebenze ngokungaphaya kwezixhobo zemveli ezikhuphisanayo ezifana nobhedu, ialuminium, kunye nentsimbi yekhabhoni.
Ukufotwa ngamaXesha eHolide eKhaya
Intsimbi engatyiwayo, ialuminiyam kunye nekomityi yeenmal zezona ziselo ziqhelekileyo kubomi banamhlanje.Phakathi kwezi zinto, ikomityi yensimbi engenasici yeyona nto iqhelekileyo yokusela, eyenziwe ngodonga oluphindwe kabini kunye nesakhiwo se-vacuum, inokugcina amanzi eshushu kunye neziselo ezibandayo.Ngaphambili, omnye wabantu base-UK wayefumene intsimbi 'engenamhlwa,' wangqina ukuba banenzame ezininzi zangaphambili.I-Brearley inikwe ikhredithi ngokuqulunqa intsimbi yokuqala eyinyani engenasici, enomxholo we-chromium we-12.8%.Wongeze ichromium kwintsimbi etyhidiweyo ukuze ivelise isinyithi esingena mhlwa.I-Chromium sisithako esiphambili, njengoko ibonelela ngokumelana nokubola.Emva kokufunyanwa, iSheffield ngokwayo iye yafana nentsimbi kunye nesinyithi.
Namhlanje, i-China lelona lizwe likhulu lithunyelwa ngaphandle kwentsimbi engatyiwayo, kwaye uninzi lwentsimbi ecocekileyo eyenziwe ngetafile, njengeendiza, icephe, imbiza, ukuvuthela, izitya, iimagi zokuhamba kunye neebhubhu njl. Nyusa.Iya kukhula ngakumbi insimbi engenasici kunye nezinto ezintsha.
Ngophuhliso lwensimbi engenasici kunye nezinto ezintsha, umzi-mveliso uya kuba yindawo ephumelelayo.
