Kuratidzwa Kwechigadzirwa
Ruzivo rweChigadzirwa
Mapaipi esimbi isina musono imapaipi esimbi anodzivirira ngura dzisina kusimba dzakadai semhepo, utsi, nemvura, uye ngura dzinoshandiswa nemakemikari dzakadai seacids, alkalis, uye munyu. Anozivikanwawo sepaipi yesimbi isingasvibi acid.
Kuramba kwesimbi isina ngura kunoenderana nezvinhu zviri musimbi. Chromium ndiyo chinhu chikuru chekudzivirira ngura kwesimbi isina ngura. Kana huwandu hwechromium musimbi hwasvika pa12%, chromium inosangana neokisijeni iri musimbi inoparadza kuti igadzire firimu rakatetepa reoxide (self-passivation film) pamusoro pesimbi. , Inogona kudzivirira ngura yesimbi. Pamusoro pechromium, zvinhu zvinowanzoshandiswa zvekubatanidza simbi isina ngura zvinosanganisira nickel, molybdenum, titanium, niobium, copper, nitrogen, nezvimwewo, kuti zvizadzise zvinodiwa zvekushandiswa kwakasiyana-siyana kwechimiro uye mashandiro esimbi isina ngura.
Pombi isina musono yesimbi isina ngura isimbi yakatenderera ine mhango yakareba, inoshandiswa zvakanyanya mumafuta, makemikari, zvokurapa, chikafu, indasitiri yechiedza, zvishandiso zvemakanika uye mamwe mapaipi emaindasitiri uye zvikamu zvemagadzirirwo emakanika. Pamusoro pezvo, kana simba rekukotama uye rekutenderera rakafanana, huremu hwacho hwakareruka, saka rinoshandiswawo zvakanyanya mukugadzira zvikamu zvemakanika uye zvivakwa zveinjiniya. Inowanzoshandiswawo kugadzira zvombo zvakasiyana-siyana zvechinyakare, mabharumu, magokora, nezvimwewo.
Maitiro Ekugadzira
