Stainless simbi handwheels ndiwo akakosha ekushandisa mumidziyo yeindasitiri, michina yekurapa, kugadzira chikafu uye mamwe minda. Maitiro avo epamusoro ekurapa anokanganisa zvakananga kusimba, kupikisa kwecorrosion uye ruzivo rwekushanda kwechigadzirwa. Kunyanya munzvimbo dzakaomarara senge mainjiniya emugungwa, kemikari corrosion, tembiricha yakakwira uye kudzvanywa kwakanyanya, kusarudzwa kwehunyanzvi hwekurapa kwepamusoro kunotarisisa hupenyu hwebasa uye kuchengetedzeka kwemidziyo. Zvichienderana nezviyero zveindasitiri uye maitiro einjiniya, chinyorwa ichi chinoongorora tekinoroji yekurapa pamusoro pemavhiri emaoko esimbi isina tsvina, uye inopa hutungamiriri hwehunyanzvi hwekugadzira uye kusarudzwa kwakabatana nezvinodiwa zvenzvimbo dzinoora.
Zviri mukati
1. Core zvinodikanwa pakurapa kwepamusoro kwesimbi isina mavhiri emaoko
2. Kuenzanisa kwakajairika pamusoro pekurapa matekinoroji
3. Kugadziriswa kwekurapa kwakakosha munzvimbo dzakaoma
4. Nzira dzekudzivirira munzvimbo dzinoora
5. Pfungwa huru dzekusarudza nzira uye kutonga kwehutano
6. Indasitiri application kesi uye maitiro ekuona
1. Core zvinodikanwa pakurapa kwepamusoro kwesimbi isina mavhiri emaoko
Kuita kwesimbi isina simbi yemaoko mavhiri munzvimbo dzakaora kunoenderana nekubatana pakati pekupokana kwekuora kwechinhu chacho uye maitiro ekurapa kwepamusoro. Tichitora 304/316 simbi isina tsvina semuenzaniso, iyo chromium yemukati inoumba passivation firimu, inova hwaro hwekudzivirira ngura, asi inoda kusimbiswazve mune zvinotevera zviitiko:
Chloride ion erosion:Munzvimbo dzemugungwa kana mamiriro ekupfapfaidza munyu, iyo passivation firimu inoparadzwa zviri nyore.
Kusangana nemakemikari media:asidhi uye alkali mhinduro, organic zvinonyungudutsa, etc. mhanyisa gomba uye kusagadzikana ngura.
Tembiricha yepamusoro uye hunyoro hwepamusoro:microbial corrosion uye oxidation reactions inokwidziridzwa munzvimbo inopisa uye ine mwando.
Mechanical kupfeka:Kushanda nguva nenguva kunokonzera kukuvadzwa kwechidziviriro chepamusoro, zvichiita kuti nzvimbo iparare.
Naizvozvo, kurapwa kwepamusoro kunofanirwa kuzadzisa zvinangwa zvitatu zvinotevera: kuwedzera hupenyu hwefirimu rekuita, kuvandudza kuomarara kwepasi, nekusimudzira kugona -kusvibisa kusvibiswa.
2. Kuenzanisa kwakajairika pamusoro pekurapa matekinoroji
(1) Mechanical treatment process
Sandblasting (pfuti peening) kurapwa
Nekukanganisa pamusoro-zvimedu zvejecha rinomhanya, chimiro cheuniform matte (Ra 3.2-6.3μm) chinogadzirwa. Chakanakira ndechekuti inobvisa iyo oxide layer uye inovandudza kusungirirwa kwejasi, iyo yakakodzera kune anti-slip zvinodiwa zveindasitiri michina handwheels. Nekudaro, zvinofanirwa kucherechedzwa kuti mushure mekuputika kwejecha, kurapwa kwepassivation kunodiwa kuti udzorere kusagadzikana kwekuora.
Wire drawing treatment
Shandisa mechanical texture kugadzirisa senge mitsetse yakatwasuka uye mitsetse isina kurongeka kuti uvandudze kukwenya kwehandwheel grip. Inowanzo shandiswa mumidziyo yekurapa mavhiri emaoko, asi corrosive media inounganidzwa zviri nyore mukuora mwoyo kwechimiro, uye yakavharwa coating inodiwa.
(2) Kemikari kurapwa maitiro
Pickling passivation
Bvisai iron mahara kuburikidza nenitric acid kana citric acid solution uye gadzirai chromium{{0}rich passivation film. Zvidzidzo zvakaratidza kuti pitting resistance yepitting 316L simbi isina tsvina mu3.5% NaCl solution inovandudzwa ne40%.
Electrochemical polishing
Dissolve the surface micro-protrusions with electric current in an acidic electrolyte kuwana girazi rinoita uku uchiwedzera density yefirimu repasi. Inokodzera chikafu-magiredhi emidziyo mavhiri emaoko kuderedza njodzi yekubatanidzwa nebhakitiriya.
(3) Tekinoroji yekuisa muviri
PVD (kuiswa mupfunga wenyama)
Deposit ceramic coatings such as TiN and CrN in a vacuum environment, with a surface hardness of more than HV2000, significantly improving wear resistance and salt spray resistance (>1000 maawa pasina tsvuku tsvuku). Iyo iPhone Stainless simbi yepakati furemu inoshandisa maitiro aya, uye yawedzerwa kusvika pakugadzira yakakwirira-mavhiri emaoko emudziyo.
3. Kugadziriswa kwekurapa kwakakosha kwenzvimbo dzakaoma
(1) Mhoteredzo yegungwa
Multi-layer composite coating: PVD CrN bottom layer + electrophoretic epoxy resin outer layer, tichifunga zvose kuoma uye kuramba kupinda chloride ion.
Micro-arc oxidation: Al₂O₃ firimu receramic rinogadzirwa mu electrolyte, uye kudzivirira kusvibiswa kwemvura yegungwa kunodarika zvakapetwa katatu pane zvechinyakare.
(2) Chemical corrosion environment
Polytetrafluoroethylene (PTFE) impregnation: PTFE zvimedu zvakaiswa mumapores eStainless simbi pamusoro kuderedza nzvimbo yekubatana pakati peasidhi nealkali media. Mushure mekurapwa, hupenyu hwepetrochemical valve handwheel mu98% sulfuric acid hwakawedzerwa kusvika kumakore mashanu.
Laser cladding: Co{{0}based alloy powder inopfekedzwa pamusoro kuti igadzire corrosion-resistant alloy layer, iyo inokodzera asidhi yakasimba pombi valve mavhiri emaoko.
(3) Kupisa kwepamusoro uye kudzvinyirira kwakanyanya
Yepamusoro tembiricha oxidation coloring: Nekudzora tembiricha yekudziya (200-300 dhigirii), Fe₃O₄ firimu layer inogadzirwa pamusoro, uye tembiricha kuramba inogona kusvika 500 degree. Inowanzo shandiswa kune boiler midziyo kugadzirisa handwheels.
Plasma nitriding: ε{{0}Fe₂-₃N chikamu chinoumbwa mumhepo yeammonia, kuoma kwepamusoro kunowedzerwa kusvika paHV1200, uye tembiricha yekupisa oxidation yakanakisa.
4. Nzira dzekudzivirira munzvimbo dzinoora
(1) Passivation firimu kusimbisa tekinoroji
Chromium-yemahara passivation agent: molybdate ne silane zvinotsiva zvechinyakare chromate, iyo inoenderana nenharaunda uye inofananidzwa nekuora. Mushure mekunge vhiri reruoko rechimwe midziyo yengarava yave chromium-yakasununguka, yakapfuura 480-awa 480-awa munyu yekuyedzwa munzvimbo inoyedzerwa yemugungwa.
(2) Inoshanda coating design
Gradient coating system: yezasi layer electroplated nickel (5-10μm) inopa cathodic dziviriro, yepakati layer PVD yakapfava AlCrN (2-3μm) inovharira zvinoparadza media, uye yekunze layer yakapfapfaidzwa nefluorinated polymer (20-30μm) inobudirira kuzvichenesa. Iyi dhizaini inobvumira vhiri remaoko kuve nehupenyu hwesevhisi yemakore masere munzvimbo yehydrogen sulfide yekunatsa.
(3) Microbial corrosion kudzivirira uye kutonga
Ag-Kudyarwa kweCu ion: Meta yesimbi inodzivirira utachiona inoumbwa pamusoro kuburikidza nemichina yekuisa ion kudzivirira kushanda kwesulfate{1}}kuderedza utachiona (SRB). Ongororo dzinoratidza kuti kukora kwegumbo remaoko rakabatwa mumvura yegungwa rine mabhakitiriya kunoderedzwa ne76%.
5. Pfungwa huru dzekusarudza nzira uye kutonga kwehutano
(1) Sarudzo sarudzo matrix
(2) Key quality control node
Pretreatment hutsanana: Surface residual girisi inofanira kunge iri Ishoma pane kana kuenzana ne5mg/m² (ISO 8502-3 standard).
Passivation firimu ukobvu: XPS bvunzo Cr/Fe reshiyo inofanira kunge Yakakura kupfuura kana kuenzana ne1.5 (ASTM A967).
Coating adhesion: Cross-cut cut test inosvika ISO 2409 Kirasi 1.
6. Indasitiri application kesi uye maitiro ekuona
(1) Muenzaniso wekuongorora nyaya
Yakadzika-sea drilling platform handwheel: AlCrN/TiSiN multilayer PVD coating inoshandiswa, uye yapfuura makore 10 ekuona sevhisi munzvimbo ine-yakanyanya kudzvanywa pakadzika 1500 metres.
Nuclear power plant control handwheel: Electrochemical polishing + molybdate passivation yakasanganiswa maitiro, radiation oxidation resistance inovandudzwa ne60%.
(2) Tekinoroji yekuvandudza maitiro
Hungwaru hwepamusoro kurapwa: Gadzirisa PVD deposition paramita kuburikidza neAI algorithm kuti uwane yakasarudzika firimu kuita.
Green process innovation: Mvura{{0}based passivation liquid uye yakaderera-tembiricha yeplasma inoderedza kushandiswa kwesimba uye kusvibiswa.
Summary
Mabatirwo epamusoro emavhiri emaoko esimbi isina tsvina munzvimbo dzakaoma uye dzine ngura inoda kutariswa kwakadzama kubva pamativi matatu: mhando yepakati, mechanical mutoro, uye mutengo wekutenderera kwehupenyu. Mune ramangwana, nebudiriro mumichina yakaita senano-coatings uye zvimiro zvebionic, kurapwa kwepamusoro kuchasimukira munzira yekubatana kwekushanda uye kuchinjika kwezvakatipoteredza. Pakusarudza nzira, mainjiniya anofanirwa kukoshesa zvimiro zvepasi rose zvakaita seASTM neISO, uye kuita ongororo dzekuchembera dzinoenderana nemamiriro ekushanda chaiwo kuti vawane mutengo wakanyanya{3}unoshanda.
