Propargyl Alcohol Corrosion Inhibitor Supplier

Chii Chinonzi Propargyl Doro?

Propargyl alcohol (2-propyn-1-ol, PA) imusanganiswa weorganic une huremu hushoma une terminal alkyne group (C≡CH) uye hydroxyl group (−OH). Imvura yakajeka, inofambiswa, inobvira moto ine hwema hunopisa. Mumakemikari ekudzivirira ngura, propargyl alcohol inoshandiswa semushonga unoshanda zvikuru wesimbi unodzivisa ngura mune acidic media - kunyanya mu hydrochloric acid (HCl) pickling, sulfuric acid descaling, uye phosphoric acid cleaning solutions. Maitiro ePropargyl alcohol ndeye adsorption: triple bond (alkyne group) inosangana nekubatana kwe catalytic ne iron surface uye inokurudzira adsorption ye organic molecule, ichigadzira organic film inodzivirira pamusoro pesimbi inovhara acid attack uye inoderedza ngura. Inoderedzawo hydrogen embrittlement ye high-strength steel panguva yekusangana ne acid.

Kubvisa Acid Pickling uye Scale Applications

Kubvisa acid muzvikamu (kuchenesa neHCl kana H₂SO₄ kubvisa ngura, chikero chemugayo, chikero checalcium carbonate, kana iron oxide deposits kubva pamusoro pesimbi) kunoisa simbi yepasi munzvimbo ine acid inoparadza zvakanyanya. Pasina chinhu chinodzivirira ngura, kurwiswa kweacid pamusoro pesimbi yakachena (pasi pechiyero) kwakanyanya uye kunokonzera kurasikirwa nesimbi, hydrogen embrittle, uye surface roughening. Propargyl alcohol, inopinzwa pa0.1–1.0% (1–10 g/L) mu acid bath, inoderedza zvakanyanya ngura yesimbi (kushanda zvakanaka kwe 90–99% mu 15% HCl pa 30–80°C, zvichienderana nedosi netembiricha) ukuwo ichibvumira acid kunyungudutsa chikero nekudonhedza. Inoenderana nezvimwe zvikamu zve acid pickling inhibitor (iodide ions, surfactants, heteroatom-containing compounds) muzvigadzirwa zve pickling inhibitor zvakagadzirwa.

Maitiro Ekuchenesa Munda weOiri neMaindasitiri

Mukushanda kwenzvimbo dzemafuta, propargyl alcohol inoshandiswa mukugadzira zvinhu zvinodzivirira acid zvinosimudzira tsime (HCl matrix acidising, acid fracturing) kudzivirira machubhu esimbi nemidziyo yemugodhi kubva kuHCl ine huwandu hwakawanda inoshandiswa mukugadzira carbonate. Zvinodiwa zveOilfield acid inhibitors zvinoda kudziviswa - kudziviswa kunofanira kuramba kuchishanda patembiricha inosvika 120–150°C pasi pehuwandu hwakawanda hweHCl (15–28%) uye kumanikidzwa kwakanyanya. Propargyl alcohol ndiyo musimboti wemhando dzakawanda dzeCommercial acid inhibitors, dzakasanganiswa neamine dzakagadzirwa, nitrogen-bearing heterocycles, uye intensifier compounds (iodide, cinnamaldehyde) yekuwedzera kupisa kwakanyanya. Mukuchenesa kweindasitiri nekuchenesa michina yekugadzira, propargyl alcohol inodzivirira nzvimbo dzesimbi panguva yekushanda kweHCl kana citric acid cleaning. Terracore Chemicals inopa propargyl alcohol mumadhiramu e25 kg ne200 kg pasi pemhando yemvura inobvira.
