Maitiro ekudzivirira ngura uye ngura pane 16Mn isina musono pombi dzesimbi?
16Mn, inozivikanwawo seQ345, imhando yekabhoni simbi isingadzivirirwe nekuora. Pasina nzvimbo yakanaka yekuchengetera uye inongoiswa kunze kana munzvimbo ine unyoro uye inotonhora yakasikwa, kabhoni simbi inoita ngura. Izvi zvinoda kubvisa ngura kuti iitwe paari.
Nzira yekutanga: kushambidza asidi
Kazhinji, nzira mbiri, organic chemistry uye electrolysis, dzinoshandiswa kunhonga asidhi kugadzirisa dambudziko. Kune simbi pombi anti-corrosion, chete organic chemistry acid pickling inoshandiswa kubvisa oxide scale, ngura, uye machira ekare. Dzimwe nguva, inogona kushandiswa semhinduro mushure mekuita jecha kubvisa ngura. Kunyangwe makemikari ekuchenesa mvura achikwanisa kuwana imwe nhanho yehutsanana hwepasi uye kushata, mitsara yayo yekumisa haina kudzika uye inogona kukonzera nyore kusvibiswa kwezvakatipoteredza kune yakasikwa nharaunda.
2: Kuchenesa
Kushandisa organic solvents uye zvinonyungudutsa kuchenesa pamusoro pesimbi kunogona kubvisa mafuta, mafuta emiriwo, guruva, lubricant, uye akafanana organic makomisheni. Zvisinei, haigoni kubvisa ngura, oxide yeganda, welding flux, nezvimwewo pamusoro pesimbi, saka inongoshandiswa senzira yekubatsira mukugadzirwa kwe-anti-corrosion uye kugadzira.
3: Zvishandiso zvakakosha zvekubvisa ngura
Zvishandiso zvakakosha zvinosanganisira kushandisa maturusi akasarudzika senge simbi mabhurashi kukwenenzvera nekukwenenzvera pamusoro pesimbi, ayo anogona kubvisa ganda re oxide, ngura, weld nodule, nezvimwewo , uye chishandiso chakakosha chekutyaira simba chinogona kuwana Sa3 level. Kana iyo nzvimbo yesimbi yakanamatira yakasimba zinc ash, iyo chaiyo yekubvisa ngura mhedzisiro yechishandiso chakakosha haina kunaka, uye haigone kusangana neiyo anchor pateni yakadzika layer inotsanangurwa mumirairo ye-anti-corrosion yefiberglass.
4: Pfapfaidza (pfapfaidza) kubvisa ngura
Kupfapfaidza (kukanda) kubvisa ngura kunowanikwa nekushandisa high-power yemagetsi mota kutyaira iyo spray (kukanda) blades kuti ishande nekumhanya kwazvo, ichibvumira kusagadzika zvinhu zvakaita segoridhe, jecha resimbi, simbi mabhora, yakanaka iron waya segment, uye zvicherwa zvekupfapfaidza (kukanda) pamusoro pemapombi esimbi asina musono pasi pesimba recentripetal. Izvi hazvingobvisi ngura, okisidhi yesimbi, uye marara chete, asi zvakare zvinowana iyo inodiwa yunifomu yekukasharara kwepombi dzesimbi dzisina musono pasi pesimba rakasimba uye kukweshera kwezvinhu zvinopfekwa.
Mushure mekupfapfaidza (kukanda) kubvisa ngura, haingogone chete kuwedzera iyo yemuviri adsorption mhedzisiro yepombi yepasi, asi zvakare inonatsiridza iyo adhesion mhedzisiro ye-anti-corrosion layer kune mechaniki midziyo iri pamusoro pepombi.
