NSEN Valve ichangobva kuita yekusarerekera munyu kupfapfaidza bvunzo yevharuvhu, uye yakabudirira kupasa bvunzo pasi peuchapupu hweTUV.Iyo pendi inoshandiswa pavharuvhu yakaedzwa ndeye JOTAMASTIC 90, bvunzo yacho inoenderana neyakajairwa ISO 9227-2017, uye uye nguva yekuyedza inotora maawa makumi mapfumbamwe nematanhatu.

Pazasi ini ndichasuma muchidimbu chinangwa chebvunzo yeNSS,

Muyedzo wekupfapfaidza munyu unoteedzera nharaunda yegungwa kana mamiriro ekunze enzvimbo dzine munyu, uye inoshandiswa kuongorora kusakara kwemunyu kupfapfaidza marara ezvigadzirwa, zvinhu uye zvidziviriro zvazvo.

Iyo munyu yekupfapfaidza test standard inotsanangura zvakajeka mamiriro ekuyedza, senge tembiricha, humidity, sodium chloride solution yekumisikidza uye pH kukosha, nezvimwewo, uye zvakare inoisa mberi tekinoroji zvinodiwa pakuita kwekamuri yekupfapfaidza munyu.Nzira dzekutonga mhedzisiro yemunyu wekupfapfaidza bvunzo dzinosanganisira: chiyero chekutonga nzira, kuyeresa nzira yekutonga, inoora inooneka nzira yekutonga, uye corrosion data statistical yekuongorora nzira.Zvigadzirwa zvinoda bvunzo yekupfapfaidza munyu zvinonyanya zvimwe zvigadzirwa zvesimbi, uye kuramba kwekuora kwezvigadzirwa kunoongororwa kuburikidza nekuyedzwa.

Iyo yekunyepedzera yakatemerwa munyu yekupfapfaidza nharaunda bvunzo ndeyekushandisa mhando yemidziyo yekuyedza ine imwe vhoriyamu nzvimbo-munyu wekupfapfaidza bhokisi rekuyedza, munzvimbo yayo yevhoriyamu, nzira dzekugadzira dzinoshandiswa kugadzira nzvimbo yekupfapfaidza munyu kuongorora kunaka kwemunyu wekupfapfaidza corrosion. kushorwa kwechigadzirwa .Kuenzaniswa nenharaunda yechisikigo, munyu wekloridhi munzvimbo yemunyu yekupfapfaidza inogona kuva akati wandei kana makumi enguva yemunyu wekupfapfaidza zviri mukati mezvakajairwa zvakatipoteredza, izvo zvinowedzera kukura zvakanyanya.Iyo munyu yekupfapfaidza bvunzo yechigadzirwa inoitwa uye mhedzisiro inowanikwa Iyo nguva zvakare yakapfupikiswa zvakanyanya.Semuyenzaniso, kana sampu yechigadzirwa ikayedzwa munzvimbo yakasarudzika, zvinogona kutora gore kuti imirire kuora kwayo, nepo bvunzo iri pasi pemaitiro akafananidzirwa emunyu wekupfapfaidza mamiriro enzvimbo inoda maawa makumi maviri nemana chete kuti uwane mibairo yakafanana.

Iyo yekusarerekera munyu yekupfapfaidza bvunzo (NSS bvunzo) ndiyo yekutanga uye yakanyanya kushandiswa yakakwirisa corrosion test nzira.Inoshandisa 5% sodium chloride munyu aqueous solution, iyo pH kukosha kwemushonga inogadziriswa mukusarerekera (6-7) semushonga wekupfapfaidza.Tembiricha yekuyedza i35℃, uye mwero wekunyungudika kwemunyu wekupfapfaidza unodiwa kuva pakati pe1～2ml/80cm²·h.
