- Kev soj ntsuam - Cov txheej tiav yog kuaj rau cov pinholes (hnub so nrhiav pom), thickness, thiab adhesion.
Epoxy Coated Yeeb Nkab
Epoxy Coated Yeeb Nkab yog cov yeeb nkab steel uas muaj txheej tiv thaiv ntawm epoxy resin siv rau nws sab hauv thiab / lossis sab nraud. Lub epoxy txheej muab kev tiv thaiv corrosion zoo heev, tshuaj tiv thaiv, thiab ua kom tiav. Tsis zoo li FBE (fusion bonded epoxy), uas yog ib qho tshwj xeeb thermoset hmoov txheej, "epoxy coated yeeb nkab" yog lub ntsiab lus dav uas tuaj yeem suav nrog cov kua epoxy txheej thiab hmoov epoxy txheej (xws li FBE).
- Kev Npaj Nto - Cov yeeb nkab steel yog abrasive- blasted rau qhov huv, ntxhib nto (feem ntau Sa 2.5 lossis hlau dawb).
- Daim ntawv thov - Epoxy yog siv los ua kua (txhaj tshuaj / txhuam) lossis ua hmoov (electrostatic tsuag rau hauv cov yeeb nkab rhuab).
- Curing - Cov txheej raug tso cai kho (rau cov kua epoxy, tshuaj lom neeg cov tshuaj tiv thaiv; rau hmoov, kub fusion).
- Kev tshuaj xyuas - Txheej thickness, adhesion, thiab pinhole - kuaj dawb.
Hom Epoxy Txheej

3PE Coated Yeeb Nkab
3PE Coated Yeeb Nkab (Peb-Txheej Polyethylene Coated Yeeb Nkab) yog cov yeeb nkab steel nrog ntau txheej los tiv thaiv- txheej txheej txheej txheej uas muaj peb txheej sib txawv: epoxy primer, nplaum copolymer, thiab txheej txheej polyethylene. Qhov kev sib xyaw no muab kev tiv thaiv corrosion zoo heev, muaj zog adhesion, thiab kev tiv thaiv zoo tshaj plaws, ua rau nws cov qauv kev lag luam rau faus thiab subsea pipelines.
- Kev Npaj Nto - Cov yeeb nkab steel yog abrasive -blasted rau Sa 2.5 (dawb hlau) thiab rhuab.
- Epoxy Daim Ntawv Thov - Epoxy hmoov yog electrostatically txau rau hauv cov yeeb nkab kub (≈200-250 degree), qhov twg nws melts thiab chemically bonds.
- Daim ntawv thov Adhesive - Thaum lub epoxy tseem reactive, cov copolymer nplaum yog extruded los yog sab - qhwv rau hauv cov yeeb nkab.
- PE Extrusion - Molten polyethylene yog extruded tshaj lub nplaum txheej, tsim ib tug nruam, seamless tsho.
- Cooling - Dej quenching solidifies txheej.
- Kev tshuaj xyuas - Kev kuaj xyuas hnub so, ntsuas qhov tuab, thiab kev kuaj adhesion yog ua.
