I-Fusion-Bonded Epoxy Coatings Awwa C213 Standard

Fusion-Bonded Epoxy Coatings Awwa C213 Standard Featured Umfanekiso

Inkcazelo emfutshane:

I-Fusion-Bonded Epoxy Coatings kunye neLinings ye-Steel Water Pipe kunye neFittings

Lo ngumgangatho weAmerican Water Works Association (AWWA).Iingubo ze-FBE zisetyenziswa kakhulu kwimibhobho yamanzi entsimbi kunye nokufakelwa, umzekelo imibhobho ye-SSAW, imibhobho ye-ERW, imibhobho ye-LSAW imibhobho engenamthungo, i-elbows, i-tee, i-reducers njl.njl. ngenjongo yokukhusela umhlwa.

Iingubo ze-epoxy eziboshwe nge-Fusion ziyinxalenye enye yeengubo ezomileyo zomgubo we-thermosetting othi, xa ubushushu busebenza, buvelise ukusabela kweekhemikhali kumbhobho wentsimbi ngelixa ugcina ukusebenza kweempawu zayo.Ukusukela ngo-1960 ukuya phambili, izicelo ziye zanda zaya kutsho kubungakanani bemibhobho emikhulu njengokwaleka kwangaphakathi nangaphandle kwigesi, i-oyile, amanzi kunye namanzi amdaka.

Iithegi zeMveliso

Iimpawu ezibonakalayo zezinto ze-epoxy powder

Umxhuzulane okhethekileyo kwi-23℃: ubuncinane yi-1.2 kunye nobuninzi be-1.8
Uhlalutyo lwe-Sieve: ubuninzi be-2.0
Ixesha legel kwi-200 ℃: ngaphantsi kwe-120s

Ukucoca ukuqhuma kwe-Abrasive

Imiphezulu yentsimbi engenanto iya kuba yi-abrasive blast-cleaned ngokuhambelana ne-SSPC-SP10 / NACE No. 2 ngaphandle kokuba kuchazwe ngenye indlela ngumthengi.Ipateni ye-ankile yokuqhushumba okanye ubunzulu beprofayili buya kuba yi-1.5 mil ukuya kwi-4.0 mil (38 µm ukuya kwi-102 µm) ilinganiswe ngokuhambelana ne-ASTM D4417.

Ukufudumala

Umbhobho ocociweyo uya kufudunyezwa kwiqondo lobushushu elingaphantsi kwe-260℃, umthombo wobushushu awuyi kungcolisa umphezulu wombhobho.

Ukutyeba

Umgubo wokugquma uya kufakwa kumbhobho oshushu ngaphambili kubunzima obufanayo bokunyanga ifilimu obungekho ngaphantsi kwe-12 mils (305μm) kumphandle okanye ngaphakathi.Ubuninzi bobukhulu abuyi kugqitha kwi-16 mils (406μm) yesiqhelo ngaphandle kokuba ucetyiswe ngumvelisi okanye uxelwe ngumthengi.

Uvavanyo lokwenziwa kwe-epoxy ngokuzikhethela

Umthengi unokucacisa uvavanyo olongezelelweyo ukuseka ukusebenza kwe-epoxy.Ezi nkqubo zilandelayo zovavanyo, zonke eziya kwenziwa kwiiringi zovavanyo lombhobho wemveliso, zingachazwa:
1. I-porosity ye-cross-section.
2. I-interface porosity.
3. Uhlalutyo lwe-Thermal (DSC).
4. Uxinzelelo olusisigxina (ukugoba).
5. Ukufunxa amanzi.
6. Impembelelo.
7. Uvavanyo lweCathodic disbondment.

Ngaphambili: Umbhobho woBuchule waseTshayina wokuFaka iPipe-iMibhobho eBande eFakelweyo, EN10219 S235JRH, S235J0H, S355JRH, S355J0H – Spiral

Okulandelayo: I-Api 5l Linemibhobho yeBanga B ukuya kwi-X70 Od ukusuka kwi-219mm ukuya kwi-3500mm
