Mutengesi weBenzotriazole (BTA) Corrosion Inhibitor South Africa

Chii chinonzi Benzotriazole?

Benzotriazole (BTA, 1H-benzotriazole) chinhu chinonhuhwirira chinonzi heterocyclic compound — chinhu chena chekristalline chinonyungudika zvine mwero mumvura. Ndiyo inonyanya kushandiswa uye inoshanda zvikuru mukudzivirira ngura yemhangura necopper alloys (brass, bronze, cupronickel) mumvura. BTA inoshanda ne chemisorption: maatomu enitrogen e triazole ring anosangana zvakananga necopper surface kuti agadzire Cu(I)-BTA polymer complex isinganyungudike, yakasimba zvikuru inoshanda sechidziviriro chemuviri chinodzivirira kuwedzera kwe oxidation yecopper surface ne dissolved oxygen, chlorine, kana zvimwe oxidants. Iyi protective film yakatetepa zvikuru (molecular monolayer) asi inoshanda zvikuru, ichideredza copper corrosion rates ne95–99% pa dosages dzakaderera se1–5 mg/L.

Kushandiswa kweKutonhodza Mvura neKupisa

Muzvirongwa zvekurapa mvura inotonhodza, zvinochinja-chinja kupisa zvemhangura nemhangura, zvinokonzeresa, uye mapaipi ndizvo zvinonyanya kukonzera ngura. Okisijeni yakanyungudutswa, chlorine, pH swings, uye ngura inokonzerwa nekukuruka kwemhepo zvinorwisa nzvimbo dzemhangura. BTA inopihwa 1–5 mg/L mumvura inotonhodza inotenderera sechikamu chemusanganiswa wezvinodzivisa ngura. Inogadzira firimu reCu-BTA rinogara riripo pamusoro penzvimbo dzese dzesimbi dzemhangura dziri muhurongwa - firimu rinogara kusvika pH 6–10 uye tembiricha inosvika ~80°C. BTA inoenderana ne molybdate, zinc, polyphosphate, uye azole-based corrosion inhibitor formulations, uye ndiyo inhibitor yesimbi yero yero muindasitiri mune zvese zvirongwa zvekudzivirira ngura mumvura inotonhodza.

Zvimwe Zvishandiso zveMaindasitiri

Kunze kwemvura inotonhodza, benzotriazole inoshandiswa muzvinwiwa zvesimbi (mafuta ekucheka, mvura yekukuya) sechinhu chinodzivirira ngura yemhangura uye sechinhu chinodzivirira ngura yemupfu. Muzvipfeko zvinodzivirira kutonhora/kutonhora (zvinopisa zvemotokari neindasitiri), BTA ndiyo chinhu chinodzivirira ngura yemhangura. Muzvinyoro zveindasitiri, BTA inowedzerwa mumafuta ehydraulic, mafuta egiya, uye mafuta eturbine kana ichibata mabheringi emhangura yemhangura kana kuti zvinochinja-chinja kupisa. Mumagetsi, BTA inoshandiswa sechinodzivirira pamusoro pemhangura mumabasa ekugadzira mabhodhi edunhu akadhindwa. Terracore Chemicals inopa benzotriazole muchimiro chehupfu (mabhegi 25 kg) uye semvura yakasanganiswa yezvirongwa zvekurapa mvura inotonhodza muSouthern Africa yese.
