Ukutshiza nge-epoxy kunye nokwaleka nge-Halar

I. Yintoni i-epoxy spray coating?

I-epoxy spray coating yi-coating enamacandelo amabini ene-epoxy resin njengento ephambili eyenza ifilimu. Isetyenziswa kumphezulu wesinyithi ngokutshiza okanye ukuxubha ukuze kwenziwe umaleko okhuselayo. Ibonakaliswa kukunamathela okuqinileyo kunye nokumelana okuhle kakhulu nokuqhekeka kwe-cathodic. I-coating enye inokufikelela kulwakhiwo oluqinileyo (ukuya kuthi ga kwi-1250 microns) ngaphandle kokugoba. Iyanyangeka kubushushu begumbi kwaye kulula ukuyakha. I-epoxy coating ifanelekile ekukhukulisekeni nasekukhuseleni ukugqwala kwe-linings zepayipi, izikhongozeli, iipompo kunye neevalvu kunye nezinye izixhobo, kwaye ubushushu bokusebenza bunokufikelela malunga ne-120°C.

II. Yintoni i-Halar coating?

IHalar ligama lorhwebo le-ECTFE (ethylene-chlorotrifluoroethylene copolymer) fluoropolymer powder coating, eyinto equlethe i-fluorine esebenza kakhulu. Isetyenziswa kumphezulu wezinto zesinyithi ngenkqubo yokutshiza nge-electrostatic, apho iqondo lokunyibilika liphakathi kwama-220-245°C kunye nobushushu obuphezulu bokusetyenziswa okuqhubekayo obuyi-150°C.

III.Yintoni umahluko phakathi kokuxhathisa ukugqwala kweekhemikhali phakathi kwezi zimbini?

Iingubo zeHalar zibanzi ngakumbi kwaye zingcono kakhulu kukumelana neekhemikhali. Ziyakwazi ukumelana phantse nazo zonke ii-asidi ezinamandla, iziseko ezinamandla kunye nezinyibilikisi ze-oZrganic ezinoluhlu lwe-pH oluyi-1-14. Zingahlala zimanziswa kwiikhemikhali ezigqithisileyo ezifana ne-98% ye-sulfuric acid egxininisiweyo kunye ne-37% ye-hydrochloric acid kwi-121°C kangangeentsuku ezingama-30. Utshintsho lobunzima bengubo lungaphantsi kwe-1% kwaye iimpawu zoomatshini azinazo utshintsho olubalulekileyo. Zinokumelana okuhle kakhulu kwamanzi kunye nokumelana nokungena, okunokuthintela ngempumelelo imidiya ebolayo ukuba ingangeni kwingubo kwaye ifikelele kwi-substrate yesinyithi. Nangona iingubo ze-epoxy nazo zinokuxhathisa kakuhle iikhemikhali, amandla azo okumelana nee-asidi ezinamandla (ezifana ne-sulfuric acid, i-hydrochloric acid) kunye namaqondo obushushu aphezulu abuthathaka kakhulu kuneengubo zeHalar.

IV.Yeyiphi engcono ngokwendlela esebenza ngayo umphezulu kunye nokuqina kwawo?

Umphezulu wengubo yeHalar uthambile kakhulu (uburhabaxa obuqhelekileyo beRa bumalunga ne-22nm kuphela), nto leyo ingcono kakhulu kunengubo ye-epoxy. Umphezulu othambileyo unokuthintela ngempumelelo ukunamathela kunye nokuqokelelwa kwamasuntswana kunye neetyuwa zesinyithi, unciphise ukwakheka kwe-biofilm, unciphise umngcipheko wemingxuma ye-pinholes, kwaye wongeze ukuthembeka kokulwa nokugqwala. Ukongeza, ingubo yeHalar iqinile, ayikrweli kwaye ayichaphazeleki, kwaye inokumelana okukhulu kwe-UV, ngoko ke ayiyi kutshabalala okanye iphele xa isetyenziswa ngaphandle.

V. Ungayikhetha njani isisombululo sokugquma esifanelekileyo?

Kucetyiswa ukuba ukhethe i-Halar coating xa——

1. Ukudibana ne-asidi enamandla, i-alkali enamandla okanye iikhemikhali ezixutyiweyo zokubola;

2. Ubushushu bokusebenza budlula i-120℃ (ubuninzi be-150℃);

3. Indawo engaphandle okanye enamandla e-ultraviolet;

4. Kufuneka umphezulu ogudileyo kakhulu ukuthintela amasuntswana ukuba anganamatheli;

Kucetyiswa ukuba ukhethe i-epoxy coating kwezi meko zilandelayo:

1. Indawo engathathi cala okanye enokutsha kancinci, amaqondo obushushu angaphantsi kwe-120°C;

2. Ixesha lokwakha lincinci kwaye lifuna ukulungiswa ngokukhawuleza;

3. Ulawulo lweendleko lungqongqo kakhulu.
