Chii chinonzi Salt Spray Test?

Nhanganyaya

Muyedzo wekupfapfaidza munyu, unonziwo bvunzo mhute yemunyu, inzira yakamisikidzwa yekuongorora kusaora kwezvishandiso uye machira ekudzivirira. Iyi yakakwirisa corrosion bvunzo inofumura masampuli kune inodzorwa mhute yemunyu, ichiteedzera mamiriro akaomarara senge nharaunda dzemugungwa kana mamiriro emahombekombe. Maindasitiri akadai semota, aerospace, uye zvemugungwa zvinovimba nebvunzo iyi kuti ive nechokwadi chekusimba uye kuita kwekuvhara. Nekutevedzera corrosion yepasirese, zvinobatsira vagadziri kufanotaura kuti zvigadzirwa zvinomira sei mumamiriro ezvinhu akaomarara nekufamba kwenguva.

 

Chii chinonzi Salt Spray Test?

1. Muyedzo wekupfapfaidza munyu ndeye kukurumidza corrosion bvunzo yakagadzirirwa kuongorora kusaora kwezvishandiso uye machira ekudzivirira. Nekuisa sampuli kumhute yemunyu kana mhute yemunyu, inotevedzera mamiriro ezvinhu akaoma seaya ari munzvimbo dzemugungwa kana mamiriro emahombekombe. Iyi yakamisikidzwa nzira, inoshandiswa zvakanyanya mumaindasitiri akadai semotokari, aerospace, uye zvemugungwa, inobatsira kuongorora kusimba kwezvinhu uye kuita kwekuvhara pasi pezvigadziriso zvinoodza.

12. Copper-Accelerated Acetic Acid-Salt Spray (CASS): Inosanganisira mhangura yekusimudzira corrosion simulation, yakanakira electroplating.

 

Muedzo weSalt Spray Unoshanda Sei?

Muyedzo wekupfapfaidza munyu inzira chaiyo yekuongorora kusakara nekufumura zviyedzo kunzvimbo inodzorwa mhute yemunyu. Iyi yakakwidziridza corrosion bvunzo, inotungamirwa nezviyero zvakaita seASTM B117 uye ISO 9227, inoteedzera mamiriro akaomarara senge nharaunda dzemugungwa kuti iongorore kusimba kwechinhu uye kuita kwekupfeka.

Salt Spray Miedzo Chamber Setup

Muedzo unoitika mukamuri yekupfapfaidza munyu, kazhinji kamuri ye412 L yakagadzirwa nePVC zvinhu kuti irambe kuora. Iyo kamuri inochengetedza tembiricha yekamuri ye35 ° C uye inoshandisa 5% munyu munyu (sodium chloride, kana NaCl) ine pH 6.5-7.2. Mhepo yakamanikidzwa inoisa mhinduro, ichigadzira mhute yakanaka yemunyu inogadzika pamasampuli.

Salt Spray MiedzoMaitiro

Iyo nzira inosanganisira:

Kugadzirira kweSample: Kuchenesa bvunzo dzemhando uye nekuisa machira ekudzivirira senge zinc coating kana sol-gel coating.

Kuisa masampuli ekuisa munyu wakafanana.

Kumhanyisa bvunzo yenguva yakatarwa yekuyedza, kazhinji maawa makumi maviri nemana-1000, uchitarisisa zvigadzirwa zvekuora senge kugadzirwa kwe ngura kana nzvimbo dzekuora.

Rinsing samples ne deionized mvura post-test kumisa ngura.

Salt Spray MiedzoMitemo uye Calibration

Kuomerera kune indasitiri zviyero seASTM B117, ISO 9227, JIS Z 2371, uye MIL zviyero zvinovimbisa bvunzo kuberekana. Calibration inochengetedza kuchena kwekemikari yemushonga wemunyu uye kunaya kwemunyu kusingachinji.

Iyi nzira inovimbisa kuvimbika kwekuyedzwa kwecorrosion kumaindasitiri senge mota, aerospace, uye zvemugungwa, inosimbisa kunamatira kwekunamatira uye kusimba kwezvinhu pasi pezvirongwa zvinodzorwa.

 

Sei Muedzo weSalt Spray Wakakosha?
