Iye zvino zvigadzirwa zvakawanda zvekugadzira maindasitiri zvichashandisa simbi isina tsvina yetambo zvinhu zvekugadzira, kuitira kuti zvionekwe simbi isina tsvina yenhema, mamwe matanho uye nzira dzinogona kutorwa.Zvisinei, vatengi vazhinji havazivi kuti ndeipi nzira inogona kushandiswa kuziva.Mhando dzinotevera dzezvitupa nzira dzakarongwa neGepair tensile mesh.
1, Magnetic bvunzo nzira
Magnetic test nzira ndiyo yakasarudzika 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 kunyura uye kunyungudutsa nitric acid, iyo inoita kuti isiyaniswe nyore kubva kune mazhinji mamwe simbi kana alloys.Zvisinei, high carbon 420 uye 440 simbi dzakasvibiswa zvishoma mu nitric acid point test, uye simbi dzisina-ferrous dzinoita ngura pakarepo mu concentrated nitric acid, nepo dilute nitric acid ine simba rekuora pa carbon steel.
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 kwekusungwa kwemhinduro yemhangura sulfate ndeye 5% - 10%, pamberi pebvunzo bvunzo, nzvimbo yekuyedza. inofanira kunyatsobvisa mafuta uye zvimwe tsvina, jira kana nyoro yekukuya kupukuta uye muchina wekukuya nzvimbo diki, uye woedza madonhwe kupisa, zvakajairika kabhoni simbi kana simbi inoumbwa mukati memasekondi mashoma A layer yepasi 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 hwesulfuric 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 sampuli dzesimbi hadzina kusvibiswa kana dzakasvibiswa zvishoma nezvishoma (hapana mabhubhu), muedzo mukati me10 ~ 15 maminitsi haashanduki ruvara.Muedzo unogona kuva wakarurama zvikuru kana sampuli ine inozivikanwa yakagadzirwa inoshandiswa pakuenzanisa kuenzanisa.
