NSEN Valve ichangobva kuita bvunzo yekuisa munyu usina kusimba pavharuvhu, uye yakapasa bvunzo iyi ichipupurirwa neTUV. Pendi yakashandiswa pavharuvhu yakaedzwa ndeye JOTAMASTIC 90, bvunzo iyi yakavakirwa paISO 9227-2017 yakajairwa, uye nguva yebvunzo iyi inotora maawa makumi mapfumbamwe nematanhatu.

Pazasi ndichatsanangura muchidimbu chinangwa chebvunzo yeNSS,

Kuyedzwa kwesauti inopfapfaidza kunotevedzera mamiriro ekunze egungwa kana mamiriro ekunze enzvimbo dzine hunyoro dzine munyu, uye kunoshandiswa kuongorora kuramba kwemushonga unopfapfaidza munyu kubva muzvinhu, zvinhu uye mativi azvo ekudzivirira.

Muyero wekuyedza salt spray unotsanangura zvakajeka mamiriro ekuyedza, akadai setembiricha, hunyoro, huwandu hwesodium chloride solution uye pH kukosha, nezvimwewo, uye unoisawo zvinodiwa zvehunyanzvi pakushanda kwekamuri yekuyedza salt spray. Nzira dzekuongorora mhedzisiro yekuyedza salt spray dzinosanganisira: nzira yekutarisa rating, nzira yekutarisa weighting juging, nzira yekutarisa corrosive appearance, uye nzira yekuongorora statistical data corrosion data. Zvigadzirwa zvinoda salt spray test kunyanya zvimwe zvigadzirwa zvesimbi, uye kuramba corrosion kwezvigadzirwa kunoongororwa kuburikidza nekuyedza.

Kuedza kwemushonga wesalt spray nharaunda yekushandiswa kwekushandisa mhando yemidziyo yekuyedza ine bhokisi rekuyedza resalt spray space-salt spray, munzvimbo yaro yehuwandu, nzira dzekugadzira dzinoshandiswa kugadzira nzvimbo yekupfapfaidza munyu kuti dziongorore mhando yekudzivirira ngura kwemushonga wesalt spray. Zvichienzaniswa nenzvimbo yezvisikwa, huwandu hwechloride munyu munzvimbo yekupfapfaidza munyu hunogona kupetwa kakawanda kana kagumi kupfuura huwandu hwesalt spray nharaunda yezvisikwa, izvo zvinowedzera zvakanyanya mwero wengura. Kuedza kwesalt spray nharaunda yemushonga kunoitwa uye mhedzisiro inowanikwa. Nguva inopfupikiswawo zvikuru. Semuenzaniso, kana sampuro yechigadzirwa ikaedzwa munzvimbo yezvisikwa, zvinogona kutora gore rimwe chete kumirira ngura yacho, nepo bvunzo iri mumamiriro ekunze ekupfapfaidza munyu wekugadzirwa kwechinhu ichi inoda maawa makumi maviri nemana chete kuti iwane mhedzisiro yakafanana.

Kuedza kwemvura isina munyu (NSS test) ndiyo nzira yekutanga uye inonyanya kushandiswa yekuyedza ngura nekukurumidza. Inoshandisa 5% sodium chloride salt aqueous solution, pH value yemvura inogadziriswa muchikamu chemvura isina munyu (6-7) semvura inopfapfaidzwa. Tembiricha yekuedza i35℃, uye mwero wemvura inopfapfaidzwa mumunyu unofanirwa kunge uri pakati pe1 ～2ml/80cm²·h.
