Iye zvino zvigadzirwa zvakawanda zvekugadzira maindasitiri zvichashandisa simbi isina tsvina yetambo zvinhu zvekugadzira, kuitira kuti zvionekwe simbi isina tsvina, mamwe matanho uye nzira dzinogona kutorwa.Zvisinei, vatengi vazhinji havazivi kuti ndeipi nzira inogona kushandiswa kuziva. Mhando dzinotevera dzezviziviso dzakarongwa neGepair tensile mesh.
1, Magnetic bvunzo nzira
Magnetic bvunzo nzira ndiyo yakanyanya yepakutanga uye yakajairika musiyano pakati peaustenitic simbi isina tsvina uye ferritic simbi isina tsvina ndiyo nzira yakapusa, austenitic simbi isina magineti haisi yemagineti simbi, asi mushure mekudzvanya kukuru kutonhora kunenge kuine magineti yakapfava; Uye yakachena chromium simbi uye yakaderera alloy. simbi isimbi yakasimba yemagineti.
2. Nitric acid point test
Chinhu chinosiyanisa chetambo yesimbi isina tsvina ndeyezvayo marara ekuramba kudzika uye kunyungudutsa nitric acid, izvo zvinoita kuti zvive nyore kusiyanisa kubva kune akawanda mamwe simbi kana alloys.Nekudaro, yakakwira kabhoni 420 uye 440 simbi dzakasvibiswa zvishoma mu nitric acid point test, uye simbi dzisina-ferrous dzinoita ngura nekukasira muconcentrated nitric acid, nepo dilute nitric acid ine simba rekuora pacarbon simbi.
3, Copper sulfate point test
Copper sulfate point edza kukurumidza kusiyanisa pakati peyakajairwa kabhoni simbi uye nzira iri nyore yemhando dzese dzesimbi isina tsvina tambo tambo, kushandiswa kweiyo kusungirirwa kwemhinduro yemhangura sulfate ndeye 5% - 10%, pamberi pebvunzo bvunzo, nzvimbo yekuyedza. inofanira kunyatsobvisa oiri nezvimwe zvitsvina, jira kana nyoro yekukuya polishing uye muchina wekukuya nzvimbo diki, wozoedza madonhwe kupisa, zvakajairika kabhoni simbi kana simbi inoumba mukati me mashoma masekonziA layer yepamusoro simbi mhangura, uye pamusoro peiyo point test Stainless simbi haiburitse kunaya kwemhangura kana kuratidza ruvara rwemhangura.
4, sulfuric acid bvunzo nzira
Sulfuric acid kunyudzwa kwesimbi isina tsvina inogona kusiyanisa 302 uye 304 kubva 316 uye 317. Mucheto wekucheka wemuenzaniso unofanirwa kuve wakatsetseka, uye wozocheneswa uye wakaiswa mu sulfuric acid nehuwandu hwehuwandu hwe20% ~ 30% uye tembiricha ye60. ~ 66 ℃ kwehafu yeawa. Kana huwandu hwehuwandu hwe sulfuric acid solution iri 10% uye inopisa kusvika 71 ℃,302 uye 304 inonyudzwa mumushonga, simbi inokurumidza kusvibiswa uye inobudisa nhamba yakawanda yemabhuru, uye sampuli inova yakasviba mumaminitsi mashomanana. 316 uye 317 simbi samples haina corroded kana corroded zvishoma nezvishoma (hapana mabubbles), bvunzo mukati me10 ~ 15 maminetsi ita. kusachinja ruvara.Muedzo unogona kuve wakanyatsojeka kana sample ine inozivikanwa maumbirwo ikashandiswa kufungidzira kuenzanisa.
