Nzira yekusarudza vharuvhu isingadziviriri? Yese kudzivirira ngura ndicho chinonyanya kukosha chinodiwa chemakemikari emidziyo. Zvechokwadi, mavharuvhu emakemikari haasiwo, uye kusarudzwa kwezvinhu zvevhavha kunofanira kunge kune anti-corrosion. Kana iyo makemikari valve yakasarudzwa zvisizvo, inokuvadza midziyo mune zvishoma, uye inokonzera njodzi huru mumatambudziko akaoma, zvichikonzera kukuvadza kumichina, midziyo uye kunyange vanhu. Nekudaro, kune akasiyana corrosive media, kusarudzwa kwemavharuvhu kwakasiyanawo. Ichi chinyorwa chinokurukura mapoinzi makuru ekusarudzwa kwezvinhu zvevharuvhu kune anowanzo shandiswa makemikari media:Anti-corrosion valve sarudzo.
Nzira yekusarudza vharuvhu isingadziviriri?
Hydrochloric acid: Zvizhinji zvesimbi, kusanganisira zvakasiyana-siyana simbi isina tsvina, haigoni kupikisa hydrochloric acid corrosion, uye high-silicon-ine ferrosilicon inogona kushandiswa chete kuhydrochloric acid iri pasi pe50 ° C uye 30%. Kusiyana nemidziyo yesimbi, zvinhu zvakawanda zvisiri-metallic zvine corrosion resistance kune hydrochloric acid, saka mavharuvhu ane rubber-lined (akadai sefluoroplastics, nezvimwewo) ndiyo yakanakisisa sarudzo yekutakura hydrochloric acid. Zvisinei, kana kutonhora kwepakati kunopfuura 150 ° C, kana kuti kudzvinyirira kwakakura kudarika 16 kg, chero plastiki (kusanganisira chlorine plastiki kana kunyange polytetraoxyethylene) ichave yakaoma kubata. Kune hydrochloric acid inodarika iyi mamiriro, hapana chinhu chakadaro pamusika. Kune mavharuvhu akanaka.Maitiro ekusarudza a Corrosion resistant valve?
Sulfuric acid: Seimwe yeakasimba ekuora media, sulfuric asidhi yakakosha mumaindasitiri mbishi zvinhu zvine huwandu hwakawanda hwekushandisa. Sulfuric acid ine huwandu hwakasiyana uye tembiricha ine musiyano mukuru mukuora kwezvinhu. Kune concentrated sulfuric acid ine concentration inopfuura 80% uye tembiricha isingasviki 80 ° C, carbon steel necast iron zvine corrosion resistance, asi haikodzere kukwira-speed kuyerera sulfuric acid. , Haina kukodzera midziyo yevharuvhu, yakajairwa Stainless simbi yakadai se304, 316 zvakare ine mashoma ekushandisa sulfuric acid yepakati. Nokudaro, mavharuvhu epombi ekutakura sulfuric acid anowanzogadzirwa ne-high-silicon cast iron (yakaoma kukanda nekugadzirisa), high-alloy stainless steel (No. 20 alloy valve), uye fluoroplastics ine yakanaka sulfuric acid resistance. s Sarudzo. Kana kudzvinyirirwa kwakanyanyisa uye kutonhora kuchikwira, nzvimbo yekushandiswa yevhavha yepurasitiki ichakanganiswa, saka iwe unogona kungosarudza bhora re ceramic iro rinodhura zvakanyanya kudarika iro.Kusarudzwa kwevhavha kune yakasimba acids uye mabhesi.
Anti-corrosion valve kusarudzwa
Nitric asidhi: Mazhinji masimbi akazara anokurumidza kuodzwa uye anoparadzwa mu nitric acid. Simbi isina tsvina ndiyo inonyanya kushandiswa nitric acid-resistant material. Iyo ine yakanaka corrosion resistance kune ese maconcentrations echokwadi acids patembiricha yekamuri. Zvinofanira kucherechedzwa kuti mhangura-ine Stainless simbi (yakadai se316, 316L) haina nani ngura inodzivirira kune acid pane yakajairwa Stainless simbi (yakadai se304, 321), dzimwe nguva yakaipisisa kupfuura.
Kusarudzwa kwevhavha kune yakasimba acids uye mabhesi
Acetic acid: Acetic acid chimwe chezvinhu zvinopisa zvakanyanya muorganic acids. Simbi yakajairika ichave yakasvibiswa zvakanyanya muacetic acid yezvese zvakadzika uye tembiricha. Simbi isina tsvina chinhu chakanakisa cheacetic acid kuramba. Aluminium-ine 316 simbi isina tsvina inokodzerawo kupisa kwakanyanya uye kunyungudutsa Acetic acid mhute. High-alloy Stainless steel kana fluoroplastic pumps inogona kusarudzwa nokuda kwepamusoro-tembiricha, high-concentration acetic acid kana zvimwe zvinopisa media.
Mvura yemunyu / mvura yegungwa: Mwero wekuora kwesimbi yakajairika muchloroform, mvura yegungwa, uye mvura yemunyu haina kunyanya kukwira. Kazhinji, machira anofanirwa kushandiswa kuchengetedza marudzi akasiyana-siyana esimbi isina tsvina. Iyo yunifomu yekuora mwero zvakare yakaderera kwazvo, asi kusvibiswa kwenzvimbo kunogona kukonzerwa neiyoni yemhepo, kazhinji Zviri nani kushandisa aluminium bronze kana 316 simbi isina tsvina.
Nzira yekusarudza vharuvhu isingadziviriri? Kana iwe uchida anti-corrosion mavharuvhu, unogona kutarisa yedu lined valve series, kana kutibata nesu kuti tisarudze
