◉Munzanga yemazuva ano, simbi isina ngura yave chinhu chinoshandiswa zvakanyanya mukuvaka, kugadzira uye muhupenyu hwezuva nezuva. Kune mhando dzakasiyana dzesimbi isina ngura, kusanganisira mhando dzakajairika dzakadai se201, 304 uye316.
Zvisinei, kune avo vasinganzwisise hunhu hwezvinhu izvi, zviri nyore kuvhiringidzika nekusiyana kuripo pakati pemhando idzi. Chinyorwa chino chichatsanangura musiyano uripo pakati pesimbi isina ngura 201, 304 na316 kuti chibatsire vaverengi kunzwisisa zviri nani mhando dzakasiyana dzezvinhu zvesimbi isina ngura uye kupa mamwe mazano ekutenga simbi isina ngura.
◉Chekutanga, mutsauko mukuumbwa kwemakemikari
Kuumbwa kwemakemikari esimbi isina ngura chinhu chakakosha pakuona mashandiro ayo uye hunhu hwayo.Simbi isina ngura 201, 304 na316 pane musiyano uri pachena mukuumbwa kwemakemikari. Simbi isina ngura 201 ine 17.5% -19.5% chromium, 3.5% -5.5% nickel, iyo uye 0.1%-0.5% nitrogen, asi haina molybdenum.
Asi simbi isina ngura 304, kune rumwe rutivi, ine 18%-20% chromium, 8%-10.5% nickel, uye haina nitrogen kana molybdenum. Kusiyana neizvi, simbi isina ngura 316 ine 16%-18% chromium, 10%-14% nickel, uye 2%-3% molybdenum. Kubva mumakemikari, simbi isina ngura 316 ine simba rekudzivirira ngura uye inodzivirira acid, yakakodzera kushandiswa mune dzimwe nzvimbo dzakakosha kupfuura simbi isina ngura 201 na304.
◉Chechipiri, musiyano mukudzivirira ngura
Kuramba ngura chiratidzo chakakosha chekushanda kwesimbi isingatsvi. Simbi isingatsvi 201 inodzivirira ngura zvakanaka kune akawanda ma organic acids, inorganic acids uye munyu solutions patembiricha yemumba, asi inozoora munzvimbo ine alkaline yakasimba. Simbi isingatsvi 304 inodzivirira ngura zvakanaka uye yakakodzera nzvimbo zhinji dzinoparadza.
Simbi isina ngura 316, kune rumwe rutivi, inobudirira mukudzivirira ngura, kunyanya munzvimbo dzine acidic uye mamiriro ekupisa kwakanyanya uye inodzivirira ngura zvakanyanya, inowanzoshandiswa mumakemikari, gungwa nedzimwe nzira. Saka, kana uchitenga zvinhu zvesimbi isina ngura, zvakakosha kusarudza modhi chaiyo zvichienderana nekushandiswa kwakaitwa munzvimbo dzakasiyana.
◉Chechitatu, mutsauko muhunhu hwemakanika
Hunhu hwesimbi isina ngura hunosanganisira zviratidzo zvakaita sekusimba, ductility uye kuomarara. Kazhinji, simba resimbi isina ngura 201 rakakwira zvishoma pane resimbi isina ngura 304, asi rakaderera zvikuru pane resimbi isina ngura 316. Simbi isina ngura 201 na304 ine ductility yakanaka, iri nyore kugadzirisa uye kugadzira, yakakodzera zvimwe zvezvinodiwa zvekugadzirisa zvinhu zvezviitiko zvepamusoro.
Simba guru resimbi isina ngura 316, asi rine simba rekudzivirira kubvaruka uye simba rekudhonza, rakakodzera kutsungirira simba rakawanda uye tembiricha yepamusoro yekushanda. Saka, pakusarudza zvinhu zvesimbi isina ngura, unofanirwa kusarudza zvinoenderana nezvinodiwa zvemakanika uye kushandiswa kwenzvimbo yacho.
◉Chechina, musiyano wemutengo
Kunewo misiyano mumutengo wesimbi isina ngura 201, 304 na316. Kazhinji, mutengo wesimbi isina ngura 201 wakaderera, unokwanisika kutenga. Mutengo wesimbi isina ngura 304 wakakwira, asi nekuda kwekushandiswa kwayo kwakasiyana-siyana uye kushanda kwayo kuri nani, ichiri imwe yemhando dzesimbi isina ngura dzakajairika pamusika.
◉ Simbi isina ngura 316 inodhura zvakanyanya nekuda kwekudzivirira kwayo ngura uye hunhu hwayo hwemakanika, uye yakakodzera kune dzimwe nzvimbo dzakakosha dzinoda hunhu hwakawanda hwezvinhu. Saka, paunenge uchitenga zvinhu zvesimbi isina ngura, unofanirwa kufunga nezvezvinhu zvakaita sekushanda kwechinhu chacho uye bhajeti.
Semutengesi wenyanzvi wezvinhu zvesimbi isingasvibi, Shanghai Qinkai Industry Co.
Fekitori iyi yakavambwa muna 2014, uye mushure memakore ekuvandudzwa, yave kambani inobatanidza kutengeswa kwemaplate, machubhu uye ma profiles.
Kutevedzera musimboti wekuti mutengi ndiye anofanirwa kutanga,Qinkaiyakazvipira kupa vatengi zvinhu zvesimbi isingasvibi zvemhando yepamusoro uye sevhisi yakanaka kwazvo!
→ Kuti uwane zvigadzirwa zvese, masevhisi uye ruzivo rwechizvino-zvino, ndapotataura nesu.
