Nheyo dzekudzivirira-corrosion coatings

news1 news2

Anti-corrosion coatings anowanzo kupatsanurwa kuita akajairwa anti-corrosion coatings uye inorema-basa anti-corrosion coatings, inova iyo yakakosha yekupfekedza mumapendi ependi.Conventional anti-corrosion coatings inoita basa rekudzivirira kuparara kwesimbi pasi pemamiriro ezvinhu uye kuchengetedza hupenyu hwebasa resimbi dzisina ferrous;heavy-duty anti-corrosion coatings inofananidzwa neyakajairwa anti-corrosion coatings, iyo inogona kuiswa munzvimbo dzine hutsinye hunoodza uye inokwanisa kuA Type yeanti-corrosion coating inowana nguva yekudzivirira yakareba kupfuura yakajairwa anti-corrosion coatings.Iyo anti-corrosion musimboti weyakajairwa anti-corrosion coatings iri munzira yekemesitiri, fizikisi uye electrochemistry.Inotevera itsanangudzo yakadzama:
1. Mushonga wemakemikari we-anti-corrosion
Iyo kemikari musimboti weanti-corrosion ndeyekudzikamisa zvinokuvadza acid-base zvinhu kuita zvisina kwazvakarerekera uye zvisingakuvadze zvinhu kuchengetedza zvinhu zviri muanti-corrosion coating kubva kune zvinoora.Mamwe maamphoteric compounds, akadai sealuminium hydroxide, barium hydroxide uye zinc oxide, anowanzowedzerwa kune anti-rust coatings.Izvi zvinhu zvinogona kuita zviri nyore neasidhi uye alkali inokuvadza zvinhu kuti uwane anti-corrosion mhedzisiro.

2. Nheyo yemuviri ye-anti-corrosion
Nheyo yemuviri ye-anti-corrosion ndeyekuparadzanisa zvinhu zvakadzivirirwa kubva kune zvekunze zvinoora zvinhu zvine anti-corrosion coating.Nheyo yemuviri yependi yependi ndeyekushandisa firimu-inogadzira mumiriri kuwana dense anti-corrosion coating kuti iparadzanise kukuvadzwa kweiyo anti-corrosion mhedzisiro pane yakadzivirirwa zvinhu.Semuyenzaniso, pendi ine mutobvu neoiri zvinogona kuumba sipo yemutobvu kuti ive nechokwadi chekuti anti-corrosion coating Iyo density.

3. Mhedzisiro ye electrochemical ye-anti-corrosion
Iyo electrochemical effect ye-anti-corrosion inoreva kuwedzerwa kwezvimwe zvinhu zvakakosha kune anti-ngura pendi, kuitira kuti kana hunyoro neokisijeni zvichipfuura nepakati pependi ye-anti-ngura, ivo vanozoita kuti vagadzire anti-corrosion ions, ichipfuura pamusoro pe. simbi dzakadai simbi, uye nokudaro kudzivirira simbi ions.Dissolution, kuzadzisa chinangwa che-anti-corrosion, iyo inonyanya kuzivikanwa yechinhu ichi chakakosha ndeye chromate.

Nzvimbo dzekushandisa dzeanti-corrosion coatings dzinonyanya kusanganisira zvinotevera zvishanu zvinhu:
①Emerging offshore engineering: kuisirwa kumahombekombe, zvivakwa zvemahombekombe uye bay, mapuratifomu ekuchera mafuta ekumahombekombe;
②Zvokufambisa zvemazuva ano: migwagwa mikuru, mabhiriji, zvikepe, midziyo, zvitima nezvitima, motokari, zvivakwa zvepa airport;
③Indasitiri yemagetsi: hydraulic midziyo, matangi emvura, matangi egasi, midziyo yekuchenesa peturu, midziyo yekuchengetera peturu (pombi dzemafuta, matangi emafuta), kutapurirana magetsi nemidziyo yekushandura, simba renyukireya, migodhi yemarasha;
④Mabhizimusi makuru emaindasitiri: midziyo yekugadzira mapepa, midziyo yekurapa, chikafu nemakemikari midziyo, mukati nekunze madziro emidziyo yesimbi, mapaipi, matangi ekuchengetera kemikari, simbi, petrochemical plant, migodhi nekunyungudutswa, simendi chirimwa midziyo, pasi, madziro, uye simende zvikamu. ine corrosive media;
⑤Zvivako zveManicipal: mapaipi egasi nezvivakwa zvawo (sematangi egasi), mapaipi egasi chaiwo, zvivakwa zvemvura yekunwa, midziyo yekurasa marara, nezvimwe.
