Ukufutha kwe-Epoxy kanye nokugqoka kwe-Halar

I. Kuyini ukumbozwa kwe-epoxy spray?

I-epoxy spray coating iyi-coating enezingxenye ezimbili ene-epoxy resin njengento eyinhloko eyakha ifilimu. Ifakwa ebusweni bensimbi ngokufafaza noma ngokuxubha ukuze kwakheke ungqimba oluvikelayo. Ibonakala ngokunamathela okuqinile kanye nokumelana okuhle kakhulu nokuqhekeka kwe-cathodic. I-coating eyodwa ingafinyelela ukwakhiwa okujiyile (kufika kuma-microns angu-1250) ngaphandle kokugoba. Iyaphola ekushiseni kwegumbi futhi kulula ukuyakha. I-epoxy coating ifanelekela ukuguguleka kanye nokuvikelwa kokugqwala kwezintambo zamapayipi, izitsha, amaphampu nama-valve kanye neminye imishini, futhi izinga lokushisa lokusebenza ngokuvamile lingafinyelela cishe ku-120°C.

II. Kuyini ukugqoka kwe-Halar?

I-Halar yigama lokuhweba le-ECTFE (ethylene-chlorotrifluoroethylene copolymer) fluoropolymer powder coating, okuyizinto eziqukethe i-fluorine esebenza kahle kakhulu. Isetshenziswa ebusweni bezinsimbi zensimbi ngenqubo yokufafaza nge-electrostatic, lapho izinga lokuncibilika liphakathi kuka-220-245°C kanye nokushisa okuphezulu kokusetshenziswa okuqhubekayo okungu-150°C.

III.Uyini umehluko ekumelaneni nokugqwala kwamakhemikhali phakathi kwalokhu okubili?

Izembozo ze-Halar ziphelele futhi zingcono kakhulu ekumelaneni namakhemikhali. Zingamelana cishe nawo wonke ama-asidi aqinile, izisekelo eziqinile kanye nezinyibilikisi ze-oZrganic ezinobubanzi be-pH obungu-1-14. Zingacwiliswa njalo kumakhemikhali aqine njenge-98% ye-sulfuric acid egxilile kanye ne-37% ye-hydrochloric acid ku-121°C izinsuku ezingu-30. Izinguquko zesisindo sezembozo zingaphansi kuka-1% futhi izakhiwo zemishini azinazo izinguquko ezibalulekile. Zinokumelana okuhle kakhulu kwamanzi kanye nokumelana nokungena, okungavimbela ngempumelelo imithombo egqwalisayo ukuthi ingene embethe bese ifinyelela isisekelo sensimbi. Nakuba izembozo ze-epoxy nazo zinokumelana okuhle kwamakhemikhali, ikhono lazo lokumelana nama-asidi aqinile (njenge-sulfuric acid, i-hydrochloric acid) kanye namazinga okushisa aphezulu libuthakathaka kakhulu kunezembozo ze-Halar.

IV.Yikuphi okungcono maqondana nokusebenza kobuso kanye nokuqina?

Ubuso be-Halar coating bubushelelezi kakhulu (ubulukhuni obujwayelekile be-Ra bungama-22nm kuphela), okuyinto engcono kakhulu kune-epoxy coating. Ubuso obubushelelezi bungavimbela ngempumelelo ukunamathela nokuqongelela kwezinhlayiya nosawoti wensimbi, kunciphise ukwakheka kwe-biofilm, kunciphise ingozi yemigodi, futhi kuthuthukise ukuthembeka kokulwa nokugqwala. Ngaphezu kwalokho, i-Halar coating iqinile, ayiklwebheki futhi ayishayisani, futhi inokumelana okuqinile kwe-UV, ngakho ngeke ifiphale noma ifiphale uma isetshenziswa ngaphandle.

V. Ungayikhetha kanjani ikhambi elifanele lokumboza?

Kunconywa ukukhetha i-Halar coating uma——

1. Ukuthintana ne-asidi enamandla, i-alkali enamandla noma amakhemikhali ahlanganisiwe aqothulayo;

2. Izinga lokushisa lokusebenza lidlula i-120℃ (ubuningi be-150℃);

3. Indawo engaphandle noma enamandla e-ultraviolet;

4. Kudingeka indawo ebushelelezi kakhulu ukuvimbela izinhlayiya ukuthi zinganamatheli;

Kunconywa ukukhetha i-epoxy coating ezimweni ezilandelayo:

1. Indawo engathathi hlangothi noma ebolile kancane, izinga lokushisa lingaphansi kuka-120°C;

2. Isikhathi sokwakha sincane futhi sidinga ukulungiswa okusheshayo;

3. Ukulawulwa kwezindleko kuqinile impela.

VI.Isiphetho

I-Tianjin Tanggu Water-Seal Valve Co., Ltdinethimba lobuchwepheshe lochwepheshe elingakwazi ukwenza ngokwezifisoamavalvu ebhabhathane, amavalvu esango, ama-valve okuhlolakanye neminye imikhiqizo yama-valve ngokwezimo zakho zokusebenza ezithile, futhi sinikeze izixazululo zokufafaza ezihlangabezana nezidingo ezithile zokulwa nokugqwala. Kungakhathaliseki ukuthi ukufutha kwe-epoxy noma ukumboza kwe-Halar, singakhetha ngokunembile izinto zokwakha futhi sizakhe ngokwesayensi ukuqinisekisa ukuthi i-valve ihlala izinzile futhi ithembekile ezindaweni ezinzima. Siyakwamukela ukuzokwethula izidingo zakho zezimo zokusebenza, futhi sizokwakha ikhambi elihlanganisiwe le-valve kanye nokumboza elikhethekile kuwe.
