Kupfapfaidza kweEpoxy uye Halar coating

I. Chii chinonzi epoxy spray coating?

Kuputira kweEpoxy spray ipurasitiki ine zvikamu zviviri ine epoxy resin sechinhu chikuru chinogadzira firimu. Inoiswa pamusoro pesimbi nekupfapfaidza kana kukwesha kuti igadzire layer inodzivirira. Inoratidzwa nekunamatira kwakasimba uye kuramba kwakanaka kuganda kwecathodic. Kuputira kamwe chete kunogona kugadzira kuvaka kwakakora (kusvika kuma microns 1250) pasina kudzika. Inoporesa patembiricha yemumba uye iri nyore kugadzira. Kuputira kweEpoxy kwakakodzera kudzivirira kukurwa kwevhu uye ngura yemapaipi, magaba, mapombi nemavharuvhu nezvimwe zvishandiso, uye tembiricha yekushanda inogona kusvika pa120°C.

II. Chii chinonzi Halar coating?

Halar izita rekutengeserana reECTFE (ethylene-chlorotrifluoroethylene copolymer) fluoropolymer powder coating, inova chinhu chine fluorine inoshanda zvakanyanya. Inoiswa pamusoro pesimbi substrates kuburikidza ne electrostatic spraying process, ine melting point iri pakati pe 220-245°C uye tembiricha yepamusoro yekushandiswa nguva dzose ye 150°C.

III.Musiyano uripo pakati pemakemikari anodzivirira ngura pakati pezviviri izvi ndeupi?

Machira eHalar akazara uye akanaka pakudzivirira makemikari. Anogona kutsungirira anenge ese maacid akasimba, mabhesi akasimba uye oZrganic solvents ane pH range ye1-14. Anogona kugara akanyikwa mumakemikari akanyanya akadai se98% concentrated sulfuric acid uye 37% hydrochloric acid pa121°C kwemazuva makumi matatu. Kuchinja kwehuremu hwemachira kuri pasi pe1% uye hunhu hwemakanika hahuna shanduko dzakakosha. Ane hydrophobicity yakanaka uye resistance yekupinda, izvo zvinogona kudzivirira zvinokuvadza kuti zvisapinde mu coating uye zvisvike pasi pesimbi. Kunyangwe machira e epoxy aine resistance yakanaka yemakemikari, kugona kwawo kutsungirira maacid akasimba (akadai sesulfuric acid, hydrochloric acid) uye tembiricha dzakakwirira hazvina kusimba zvakanyanya pane machira eHalar.

IV.Ndeipi iri nani maererano nekushanda kwepamusoro uye kugara kwenguva refu?

Pamusoro peHalar coating pakanyatsotsvedzerera (avhareji roughness Ra inongova 22nm), izvo zviri nani pane epoxy coating. Pamusoro payo pakanyatsotsvedzerera panogona kudzivirira kubatana uye kuunganidzwa kwezvidimbu nemunyu wesimbi, kuderedza kuumbwa kwebiofilm, kuderedza njodzi yemaburi, uye kuwedzera kuvimbika kwekudzivirira ngura. Pamusoro pezvo, Halar coating yakasimba, haikwenyi uye haikanganiswi, uye ine simba rekudzivirira UV, saka haizotsvedzi kana kupera kana ikashandiswa panze.

V. Ungasarudza sei mhinduro yakakodzera yekuputira?

Zvinokurudzirwa kusarudza Halar coating kana——

1. Kusangana neasidhi yakasimba, alkali yakasimba kana makemikari akasiyana-siyana anoparadza;

2. Tembiricha yekushanda inodarika 120℃ (yakanyanya 150℃);

3. Nzvimbo yekunze kana kuti ine ultraviolet yakasimba;

4. Nzvimbo yakapfava zvikuru inodiwa kudzivirira kuti zvidimbu zvisabatire;

Zvinokurudzirwa kusarudza epoxy coating mumamiriro ezvinhu anotevera:

1. Nzvimbo isina kupindirana kana kuti isina kupinza zvakanyanya, tembiricha iri pasi pe120°C;

2. Nguva yekuvaka yakamanikana uye inoda kugadziriswa nekukurumidza;

3. Kudzora mutengo kwakaoma.

VI.Mhedziso

Tianjin Tanggu Mvura-Chisimbiso Valve Co., Ltdine timu yehunyanzvi inogona kugadzirisa zvinhumavharuvhu eshavishavi, mavharuvhu egedhi, mavharuvhu ekuongororanezvimwe zvigadzirwa zvevharuvhu zvinoenderana nemamiriro ako chaiwo ekushanda, uye kupa mhinduro dzekupfapfaidza dzinosangana nezvinodiwa zvekudzivirira ngura. Ingave epoxy spraying kana Halar coating, tinogona kusarudza zvinhu nemazvo uye kuzvigadzira nesainzi kuti tive nechokwadi chekuti vharuvhu inoramba yakasimba uye yakavimbika munzvimbo dzakaoma. Tinokugamuchirai kuti mutaure zvinodiwa nemamiriro enyu ekushanda, uye tichagadzira mhinduro yakabatana yevharuvhu necoating.
