Kev Siv Kauv Submerged Arc Vuam Ntawm Cov Kav Dej Polyethylene Lined
Taw qhia peb cov yeeb nkab polypropylene uas muaj kab rov tav, qhov kev daws teeb meem zoo tshaj plaws raucov kav dej hauv av cov kab ke. Peb cov kav dej polypropylene yog tsim los ntawm kev siv cov thev naus laus zis siab heev uas muab kauv submerged arc welding, kom ntseeg tau tias zoo thiab ruaj khov. Cov kav dej zoo tshaj plaws no yog tsim los ua kom tau raws li cov qauv siab tshaj plaws rau kev muab dej hauv av, muab kev daws teeb meem txhim khu kev qha thiab kav ntev rau ntau yam kev siv.

Fusion-Bonded Epoxy Coatings Awwa C213 Txheem
Cov Txheej Txheem Epoxy Fusion-Bonded thiab Linings rau Cov Yeeb Nkab Dej Hlau thiab Cov Khoom Siv
Qhov no yog tus qauv ntawm American Water Works Association (AWWA). Cov txheej txheem FBE feem ntau yog siv rau cov kav dej hlau thiab cov khoom siv, piv txwv li cov kav dej SSAW, cov kav dej ERW, cov kav dej LSAW, cov kav dej tsis sib xws, lub luj tshib, cov tees, cov reducers thiab lwm yam rau lub hom phiaj ntawm kev tiv thaiv xeb.
Cov txheej epoxy fusion-bonded yog ib feem ntawm cov hmoov qhuav thermosetting coatings uas, thaum cua sov ua haujlwm, tsim cov tshuaj tiv thaiv rau ntawm cov yeeb nkab hlau thaum tswj hwm kev ua tau zoo ntawm nws cov khoom. Txij li xyoo 1960, daim ntawv thov tau nthuav dav mus rau cov yeeb nkab loj dua li cov txheej sab hauv thiab sab nraud rau cov roj, roj, dej thiab cov dej khib nyiab.
