Maitiro ekuyedza iyo Corrosion Resistance yeRoller Chains

Maitiro ekuyedza iyo Corrosion Resistance yeRoller Chains

Mumaindasitiri ekushandisa, iyo corrosion kuramba yemaroller cheni chimwe chezvinhu zvakakosha zvekuvimbika kwavo uye kusimba. Hedzino nzira shoma dzekuyedza corrosion resistance yeroller cheni:

1. Munyu wekupfapfaidza bvunzo
Iyo munyu yekupfapfaidza bvunzo ndeye yakakwirisa corrosion bvunzo inoshandiswa kutevedzera kuora kwemamiriro ekunze emugungwa kana nharaunda dzemaindasitiri. Mukuyedza uku, mhinduro ine munyu inopfapfaidzwa mumhute kuti iongorore kusaora kwemarara emidziyo yesimbi. Muedzo uyu unogona kukurumidza kutevedzera maitiro ekuora munzvimbo yechisikigo uye kuongorora mashandiro ezveroller cheni zvinhu munzvimbo dzekupfapfaidza munyu.

2. Kunyudzwa bvunzo
Muedzo wekunyudza unosanganisira kunyudza mufananidzo wacho zvachose kana kuti zvishoma munzvimbo ine ngura kuti utevedzere zviitiko zvekuora kwemvura kana nharaunda dzinoita ngura. Iyi nzira inogona kuongorora mashandiro emaketani anomonereka kana akafumurwa kune corrosive media kwenguva yakareba

3. Electrochemical test
Iyo electrochemical bvunzo ndeyekuyedza zvinhu kuburikidza ne electrochemical workstation, kurekodha yazvino, voltage uye zvingango chinja, uye kuongorora kushora kwechinhu mumhinduro ye electrolyte. Iyi nzira inokodzera kuongorora kuomarara kwekushomeka kwezvinhu zvakaita seCu-Ni alloys

4. Muedzo wemamiriro ekunze chaiwo
Iyo roller chain inoratidzwa kune chaiyo yekushanda nharaunda, uye iyo corrosion kuramba inoongororwa nekutarisa nguva dzose kupfeka, corrosion uye deformation yeketani. Iyi nzira inogona kupa data pedyo nemamiriro chaiwo ekushandisa

5. Coating performance test
Kune cheni dzakavharidzirwa-dzinodzivirira kurora, zvakakosha kuti uedze mabatiro ekupfeka kwayo. Izvi zvinosanganisira kufanana, kusungirirwa kwekuputira, uye kudzivirira kwemaitiro pasi pemamiriro ezvinhu chaiwo. Iyo "Technical Specifications yeCoated Corrosion-Resistant Roller Chains" inojekesa zvinodiwa nekuita, nzira dzekuyedza uye hunhu hwekutonga zviyero zvechigadzirwa.

6. Kuongorora kwezvinhu
Kuburikidza nekuongororwa kwemakemikari ekuumbwa, kuomarara kuyedzwa, metallographic chimiro chekuongorora, nezvimwe, zvinhu zvemukati zvechikamu chimwe nechimwe cheni yeroller zvinoedzwa kuti zvione kana zvichisangana nezviyero, kusanganisira kuramba kwayo kutu.

7. Kupfeka uye corrosion resistance test
Kuburikidza nemiedzo yekupfeka uye corrosion bvunzo, kupfeka uye kusimba kwekudzivirira kweketani kunoongororwa.

Kuburikidza nenzira dziri pamusoro apa, kupikisa kwecorrosion yeroller cheni inogona kuongororwa zvizere kuti ive nechokwadi chekuvimbika kwayo uye kusimba pasi pemamiriro akasiyana ezvakatipoteredza. Iyi mhedzisiro yebvunzo ndeyekukoshera kutungamira pakusarudza yakakodzera roller cheni zvinhu uye magadzirirwo.

Nzira yekuita sei salt spray test?

Muyedzo wekupfapfaidza munyu inzira yekuyedza inoteedzera maitiro ekuora mugungwa kana nharaunda ine munyu uye inoshandiswa kuongorora kushora kwekupokana kwezvinhu zvesimbi, machira, electroplating layer uye zvimwe zvinhu. Aya anotevera ndiwo matanho chaiwo ekuita bvunzo yekupfapfaidza munyu:

1. Kugadzirira kuedza
Midziyo yekuyedza: Gadzirira munyu yekupfapfaidza kamuri yekuyedza, inosanganisira yekupfapfaidza system, yekudziya system, tembiricha yekudzora system, nezvimwe.
Test solution: Gadzirira 5% sodium chloride (NaCl) solution ine pH value yakagadziriswa pakati pe6.5-7.2. Shandisa mvura yakasvibiswa kana mvura yakasvibiswa kugadzirira mhinduro
Kugadzirira kwemuenzaniso: Muenzaniso unofanirwa kuva wakachena, wakaoma, usina mafuta uye zvimwe zvinosvibisa; saizi yemuenzaniso inofanirwa kusangana nezvinodiwa zvekamuri yekuyedza uye ive nechokwadi chakaringana nzvimbo yekuratidzira

2. Kuiswa kwemuenzaniso
Isa sampuli mukamuri yekuyedza ine nzvimbo huru yakarereka 15 ° kusvika 30 ° kubva pamutsetse wekugadzirisa kudzivirira kusangana pakati pemasamples kana kamuri.

3. Matanho ekushanda
Gadzirisa tembiricha: Gadzirisa tembiricha yekamuri yekuyedza uye dhiramu remvura yemunyu kusvika pa35°C
Kupfapfaidza dzvinyiriro: Chengetedza kupfapfaidza kudzvanya kuri 1.00±0.01kgf/cm²
Mamiriro ekuedzwa: Mamiriro ekuedzwa anoratidzwa muTebhu 1; nguva yekuyedza inguva inoenderera kubva pakutanga kusvika pakupera kwekupfapfaidza, uye nguva chaiyo inogona kubvumirana nemutengi nemutengesi.

4. Nguva yekuedza
Seta nguva yekuyedza zvinoenderana neakakodzera zviyero kana bvunzo zvinodiwa, senge maawa maviri, maawa makumi maviri nemana, maawa makumi mana nemasere, nezvimwe.

5. Kurapa mushure mekuedzwa
Kuchenesa: Mushure mebvunzo, geza zvidimbu zvemunyu zvakanamirwa nemvura yakachena iri pasi pe38°C, uye shandisa bhurasho kana chipanji kubvisa zvinosvibisa kunze kwenzvimbo dzine ngura.
Kuomesa: Pukuta sampuli kwemaawa makumi maviri nemana kana nguva yakatarwa mumagwaro akakodzera pasi pemamiriro ekunze emuchadenga ane tembiricha (15°C ~ 35°C) uye hunyoro husina kukwira kudarika 50%

6. Zvinyorwa zvekucherechedza
Kuongororwa kwechitarisiko: Ongorora sampuli zvinoenderana nemagwaro akakodzera uye rekodha mhinduro dzekuongorora
Corrosion chigadzirwa ongororo: Kemikari ongorora zvigadzirwa zvekuora pane iyo sampuli nzvimbo kuti uone mhando uye dhigirii rekuora.

7. Kuongororwa kwemhedzisiro
Ongorora kushorwa kwekupokana kwemuenzaniso zvinoenderana neakakodzera zviyero kana zvinodiwa nevatengi
Matanho ari pamusoro apa anopa yakadzama yekushandisa gwara remunyu wekupfapfaidza bvunzo kuti ive nechokwadi chechokwadi uye kuvimbika kwemhedzisiro yebvunzo. Kuburikidza nematanho aya, kusadzivirirwa kwekuora kwezvinhu munzvimbo yemunyu yekupfapfaidza inogona kunyatsoongororwa.
