Zvinonyatsozivikanwa kuti kukuvadzwa kwesimbi kunokanganisa zvakanyanya pahupenyu hwevharuvhu, kuvimbika uye hupenyu hwebasa.Chiito chemakanika uye corrosive zvinhu pasimbi inowedzera zvakanyanya kupfeka kwese kwenzvimbo yekubata.Huwandu hwese hwekupfeka pane frictional surface yevhavha panguva yekushanda.Munguva yekushanda kwevharuvhu, nzvimbo dzinopokana dzinopfekwa uye dzakakuvadzwa nekuda kwekusangana kwemakanika uye kemikari kana electrochemical pakati pesimbi nenharaunda.Kune mavharuvhu, mamiriro ekunze ekushanda kwavo kwepombi yakaoma, uye kuvapo kwehydrogen sulfide, carbon dioxide uye mamwe organic acids munhau senge oiri, gasi rechisikigo uye reservoir mvura inowedzera simba rinoparadza resimbi uye nekukurumidza kurasikirwa. kugona kushanda.

Kuora kwekemikari kwesimbi kunoenderana nekupisa, kurongeka kwemagetsi ezvikamu zvinokweshana, ma sulfide ari mumidziyo yekuzora, kugadzikana kweasidhi kuramba, nguva yekubata kwepakati, catalysis yesimbi kune nitriding process, kumhanya kweiyo molecule-ku-metal kutendeuka kwezvinhu zvinopisa, nezvimwewo.Naizvozvo, mavharuvhu esimbi anorwisa-corrosion nzira (kana zviyero) nekushandiswa kwemavharuvhu ekugadzira zvinhu, inozova imwe yezvino indasitiri yevharuvhu misoro yetsvakiridzo.

1. Anti-corrosion yeMetal Valve

Metal Valves inodzivirirwa kubva pakuora nekuiputira nejira rekudzivirira (pende, pigment, lubricating material, etc.) inodzivirira valve kubva pakuora panguva yekugadzira, kuchengetedza, kutakura, uye kushandiswa.

Nzira yeAnticorrosion yeMetal Valve inoenderana nenguva yekudzivirira inodiwa, kutakura uye kuchengetedza mamiriro, maitiro ekuvaka valve uye zvinhu, zvechokwadi, kufunga nezvehupfumi hwekusimudza anticorrosion.

Pane nzira ina huru dzekudzivirira ngura yeMetal Valves uye zvikamu zvadzo:

1.1 Bvisa iyo inoputika corrosion inhibitor mumhepo yemhute (yakaputirwa nebepa rekudzima, rinopeperetswa nemukamuri yechigadzirwa, nezvimwewo).

1.2 Shandisa mhinduro dzemvura yakavharika uye doro.

1.3 Isa jira rakatetepa rezvinhu zvinodzivirira kupisa pamusoro pevharuvhu nezvikamu zvayo.

1.4 Isa firimu rakavharika kana firimu repolymer pamusoro pevharuvhu nezvikamu zvayo.

2. Kushandiswa Kwezvinhu Valve

Mavharuvhu eSynthetic akakwirira kune mavharuvhu esimbi mumamiriro mazhinji ekuora, kutanga mukusagadzikana, kechipiri muhuremu hwemambure, uye simba rawo rinoenderana nechimiro, kuronga, uye nhamba yekusimbisa fiber.(kazhinji, iyo yakakura chikamu chefiber, iyo yakakura simba reiyo composite.)

Mumashandisirwo eValve, huremu hwehuremu hwefiber huri pakati pe30% -40%, uye kugadzikana kwayo kwemakemikari kunonyanya kutsanangurwa neresin noumenon maitiro eiyo encapsulated fiber mune yekupedzisira chigadzirwa.Mumavharuvhu ekugadzira, muviri wakasimba wepolymer unogona kunge uri Thermoplastic (sePVC-polyvinylidene fluoride, PPS-poly (p-phenylene sulfide), nezvimwewo) kana thermosetting resin (senge polyester, ethylene uye epoxy, nezvimwewo) .

Thermosetting resin inochengetedza simba rayo patembiricha yepamusoro kupfuura iyo Thermoplastic resin (kureva kuti thermosetting resin ine tembiricha yekupisa kwepamusoro).
