Corrosion ndeimwe yenjodzi dzemakemikari emusoro musoro. Kusangwarira kudiki kunogona kukuvadza midziyo, kana kukonzera tsaona kana njodzi. Zvinoenderana nehuwandu hwakakodzera, inenge 60% yekukuvara kwemakemikari emidziyo inokonzerwa nekuora. Naizvozvo, hunhu hwesainzi hwekusarudzwa kwezvinhu hunofanirwa kutariswa pakusarudza vheji yemakemikari.
Pfungwa huru dzekusarudza zvinhu:
1. Sulfuric asidhi yakakosha maindasitiri mbishi zvinhu zvine huwandu hwakawanda hwekushandisa. Sulfuric asidhi yeakasiyana siyana uye tembiricha ine misiyano mikuru mukuora kwezvinhu. Simbi yekabhoni uye simbi yakakandwa zvine corrosion resistance, asi haina kukodzera kuyerera kwe sulfuric acid uye haina kukodzera kushandiswa. Zvinhu zvepombi valve. Nokudaro, mavharuvhu epombi e sulfuric acid anowanzo kugadzirwa ne-high-silicon cast iron uye high-alloy stainless steel.
2. Zvinhu zvakawanda zvesimbi hazvigadziriswi nehydrochloric acid corrosion. Kusiyana nemidziyo yesimbi, zvinhu zvakawanda zvisiri zvesimbi zvine kunaka kwekusagadzikana kwehydrochloric acid. Naizvozvo, mavharuvhu erabha nemavharuvhu epurasitiki akaiswa hydrochloric acid ndiyo sarudzo dzakanakisa dzekutakura hydrochloric acid.
3. Nitric acid, simbi zhinji dzinokurumidza kusvibiswa uye dzinoparadzwa mu nitric acid. Stainless simbi ndiyo inonyanya kushandiswa nitric acid inodzivirira zvinhu. Iyo ine yakanaka corrosion resistance kune ese maconcentrations e nitric acid patembiricha yemumba. Pakupisa kwepamusoro nitric acid, titanium netitanium zvinowanzo shandiswa. Alloy zvinhu.
4. Acetic acid ndeimwe yezvinhu zvinopisa zvakanyanya muorganic acids. Simbi yakajairika ichave yakasvibiswa zvakanyanya muacetic acid pane zvese zvakadzika uye tembiricha. Simbi isina tsvina yakanakisa acetic acid inodzivirira zvinhu, iyo ine hukasha pakupisa kwepamusoro uye yakanyanya kutenderera acetic acid kana imwe corrosive media. Pazvinenge zvichidiwa, mavharuvhu esimbi asina simbi kana kuti fluoroplastic valves anogona kusarudzwa.
