I-NSEN Valve kutshanje yenze uvavanyo lokutshiza ityuwa olungathathi hlangothi lwevalve, kwaye lwaphumelela uvavanyo phantsi kobungqina be-TUV.Ipeyinti esetyenziselwa i-valve ihlolwe yi-JOTAMASTIC 90, uvavanyo lusekelwe kumgangatho we-ISO 9227-2017, kwaye ixesha lokuvavanya lihlala iiyure ezingama-96.

Ngezantsi ndiza kwazisa ngokufutshane injongo yovavanyo lwe-NSS,

Uvavanyo lwesitshizi setyuwa lulinganisa imo engqongileyo yolwandle okanye imozulu yeendawo ezinetyuwa efumileyo, kwaye isetyenziselwa ukuvavanya ukuxhathisa kwetyiwa yokutshizwa kwetyuwa kwiimveliso, imathiriyeli kunye nemigangatho yazo yokukhusela.

Umgangatho wovavanyo lwesitshizi setyuwa uchaza ngokucacileyo iimeko zovavanyo, ezifana nobushushu, ukufuma, ukugxininiswa kwesisombululo sesodium chloride kunye nexabiso le-pH, njl.Iindlela zokugweba iziphumo zovavanyo lwesitshizi setyuwa ziquka: indlela yokugweba yokulinganisa, indlela yokugweba, indlela yokugweba yenkangeleko enomhlwa, kunye nendlela yohlalutyo lweenkcukacha-manani zomhlwa.Iimveliso ezifuna uvavanyo lwesitshizi setyuwa ubukhulu becala ziimveliso zentsimbi, kwaye ukuxhathisa kokubola kweemveliso kuphandwa ngovavanyo.

Uvavanyo lokusingqongileyo olulinganisiweyo lokutshiza ityuwa kukusebenzisa uhlobo lwezixhobo zovavanyo ezinomthamo othile wesithuba-ityuwa yokutshiza ibhokisi yovavanyo, kwindawo yayo yomthamo, iindlela ezenziweyo zisetyenziselwa ukudala indawo yokutshiza ityuwa ukuvavanya umgangatho wokuthotywa kwetyuwa. ukumelana kwemveliso .Xa kuthelekiswa nokusingqongileyo kwendalo, ityuwa yokuxinana kwekloridi kwindawo yokutshiza ityuwa inokuba ngamaxesha amaninzi okanye amashumi amaxesha okutshizwa ngetyuwa kubume bendalo jikelele, nto leyo eyandisa kakhulu isantya sokuhlwa.Uvavanyo lokutshiza ityuwa lwemveliso luyenziwa kwaye umphumo ufunyenwe Ixesha libuye lifinyezwe kakhulu.Umzekelo, ukuba isampulu yemveliso ivavanyiwe kwindawo yokuvezwa kwendalo, kunokuthatha unyaka om-1 ukulinda ukubola kwayo, ngelixa uvavanyo oluphantsi kweemeko zokusingqongileyo zokutshiza ngetyuwa lufuna iiyure ezingama-24 kuphela ukufumana iziphumo ezifanayo.

Uvavanyo olungathathi hlangothi lokutshiza ityuwa (uvavanyo lwe-NSS) yeyona ndlela yakuqala neyeyona isetyenziswa ngokubanzi ekhawulezileyo yovavanyo lwe-corrosion test.Isebenzisa i-5% ye-sodium chloride isisombululo se-aqueous, ixabiso le-pH lesisombululo lihlengahlengiswa kuluhlu olungathathi hlangothi (6-7) njengesisombululo sokutshiza.Ubushushu bovavanyo yi-35℃, kwaye izinga lentlenga lesitshizi setyuwa liyafuneka ukuba libe phakathi kwe-1～2ml/80cm²·h.
