Kuverenga kwakawanda kwezvinhu zvesimbi kunoitika munharaunda yemagariro, nekuti mamiriro ekunze ane zvikamu zvakashata zvakadai seokisijeni uye kusvibisa, pamwe nezvinhu zvakashata senge zvinyoro uye tembiricha shanduko. Munyu Spray Corrosion ndeimwe yeiyo yakajairika uye inoparadza kutapwa kwehutachiona.
Nheyo yeMunyu Spray Corrosion
Iko kuenderana kwezvinhu zvesimbi neunenge sputa chinonyanya kukonzerwa nekupinda kwekutaura kwemunyu mune simbi uye kuumba maitiro ezvekuita micro Electron kushandisirwa kunoitika, uye simbi sezvo anodedza uye anoumba idzva denderedzwa, kureva kuparadzira. Chloride ion anoita basa rakakura mukukanganisa maitiro ekuparadza munyu, ayo ane simba rakasimba renyama, nyore kupinza nzombe yesimbi musimbi, kuparadza iyo isimbi yesimbi; Panguva imwecheteyo, chloride ion ine simba rakakura kwazvo hydration, iyo iri nyore kuve nyore kune pamusoro pesimbi, kutsiva oksijeni mudanga renzombe, zvekuti simbi yakakanganisika.
Munyu Spray Corrosion Test nzira uye kuiswa
Salt Spray bvunzo ndeyekuwedzera kushatisa kupesana yekuongorora nzira yekuongorora mamiriro ekunze mamiriro ekunze. Iko kusunganidzwa kwebrine atomized; Wobva wapfirwa muBhokisi rakavharwa remitambo, nekucherechedza shanduko yemuenzaniso yakaiswa mubhokisi kwenguva yenguva yekutsikiswa kwekuyedzwa, nzira inokurumidza , asi iyo nyika yakasarudzika yemunyu inosvina kakawanda kana nguva zhinji, kuitira kuti mwero wekushora wakavandudzwa, munyu wakasvinudza bvunzo pachigadzirwa, nguva yekuwana mhinduro dzakanyatsoderedzwa.
Munyu spray bvunzo isati yasvika uye mushure
Iyo nguva yekudyara yemuenzaniso yechigadzirwa inogona kutora gore kana kunyange makore akati wandei kana akaedzwa munzvimbo dzakasikwa, asi mhedzisiro yakafanana inogona kuwanikwa mumazuva kana kunyange maawa kana akaedzwa mukuongorora munyu wenyu munyu wakasvinudza.
Munyu Spray bvunzo dzinokamurwa kuita marudzi mana:
① Pasina Call Salt Spray bvunzo (NSS)
② acetic acid spray bvunzo (aass)
③ Copper yakawedzera acetic acid spray bvunzo (cass)

Nzira yekuongorora kuvapo kwemakoronga
Iyo Corrosion Yekuongorora nzira ndeyekutsunga kwemishini, zvinoenderana nemufaro wekuparadza kwehukama, kungave iko kugadzirwa kwechigadzirwa chiitiko kuti uone muenzaniso. Semuenzaniso, JB4 99-1999, GJB4.11-1983, GB / T 428888-2003 yakatora nzira iyi kuti uongorore mhedzisiro yemunyu.
Corrosion yehunhu tafura yematare eElectroplating zvikamu mushure mekunge munyu spray bvunzo
Currenclation nzira yeiyo Corrosion Rate:
01
Hunyoro hwakakosha hwekunyorovesa kwesimbi Corrosion ndeye inenge 70%. Kana hukama hwehukama hwasvika kana kupfuura humbowo hwakanyanya, munyu huchave hwakaoma kuti ugadzire maElektlete neakanaka maitiro. Kana hukama hwehama padzinodzikira, kusimbisa kwemunyu kunowedzera kusvika munyu werudzi rwacho wakarukwa, uye huwandu hwekushora huchadzikira saizvozvo. Sezvo tembiricha inowedzera, iyo molecular yekufambisa inowedzera uye iyo corrosion chiyero chekuputika munyu kwakakwirira kunowedzera. Iyo International Electrotechnical Commission Inotaura kuti chiyero cheCorrosion chinowedzera ne2 ~ 3 times uye iyo magetsi eElectrolyte inowedzera ne10 ~ 20% yegumi negumi 【Kuwedzera kwegumi. Zvemunyu wemunyu wakasvinudza bvunzo, zvinowanzoonekwa seyekuti 35 ℃ ndiyo tembiricha yakakodzera.02Kusunganidzwa kwemhinduro
Iyo nzvimbo yekuisa yeiyo sampuli
Kutungamira kwekupedzisira kwekupfira kwemunyu kuri pedyo neyakagadziriswa kutungamira. Kana sampuro inoiswa yakatwasuka, nzvimbo yayo yekufungidzira ndiyo yakakura, uye sampula yemuenzaniso inotakura iyo yakawanda spray, saka kuora ndiko kwakanyanya. Mhedzisiro yacho inoratidza kuti kana iyo Simbi Plate is 45 ° kubva pamutsara wakarukwa GB / T 2423.17-1993 Standard Inoti: "Nzira yekuisa sampuli yemuenzaniso ichave yakadaro kuti nzvimbo yakayedzwa ichave iri pakona ye30 ° kubva kugwara renzvimbo".
