Ngokwembono yoluhlu lobushushu bokugquma, i-epoxy powder yokwambathisa kunye ne-polyurea anti-corrosion coating ingasetyenziswa ngokuqhelekileyo kwindawo ezingqonge umhlaba onomhlwa ukusuka -30 °C okanye -25 °C ukuya kwi-100 °C, ngelixa i-polyethylene yesakhiwo esinemigangatho emithathu. iqondo eliphezulu lobushushu benkonzo yokwaleka okuchasene nomhlwa yi-70 ℃. Ngokumalunga nobukhulu bokugquma, ngaphandle kweengubo ezimbini zomgubo we-epoxy, ubukhulu bezinye iingubo ezintathu zonke zingaphezulu kwe-1mm, ekufuneka zihlelwe kudidi lweengubo ezishinyeneyo.
Enye yezinto ngokubanzi zomgangatho wokugquma wemibhobho yimpahla yomatshini kunye neyomzimba yokwaleka, oko kukuthi, eyona meko inokuqubisana nayo kwinkqubo yolwakhiwo lombhobho, njengokuqwalasela ukugotywa kombhobho emva kokuwelda kunye nokunyuswa okusezantsi. umsele ngexesha lokwakhiwa kombhobho omde. Izinto zesalathiso zokumelana nobushushu obuphantsi ziqulunqwe ngokweedamitha ezahlukeneyo zombhobho, izinto zokumelana nempembelelo yokwambathisa zichongwa ngumonakalo wokungqubana obangelwa kukuthuthwa kwemibhobho kunye nokuzaliswa ngasemva, ukuchasana nokukrwempa kunye nokuchasana nokukrweleka kweengubo kumiselwa yimikrwelo kwaye imivumbo xa imibhobho inqumla. Ukugqoka ukuxhathisa, njl njl. Ngokombono wezi mpawu, kungakhathaliseki ukuba i-epoxy powder coating, isakhiwo se-three-layer okanye i-polyurea yokugqoka, zonke zisebenza kakuhle, kodwa ngokwemiqathango yobuninzi bokugquma, i-polyethylene enemigangatho emithathu inexabiso eliphezulu lokumelana nempembelelo, ngelixa ukutshiza Ubuncinci bexabiso lokumelana nempembelelo ye-14.7J ye-polyurea yokukhusela yokukhusela nayo ihle kakhulu.
Ekubeni ukugquma kwemibhobho emide isetyenziswa kakhulu ngokudibanisa nokukhusela i-cathodic, ukuyilaumbhobho wokugqumaizalathisi zinika ingqwalasela engakumbi ekusebenzeni kwe-anti-cathodic disbondment of the coating, ngaloo ndlela kusekwa iiprojekthi zexesha elifutshane kunye nexesha eliphakathi lokuchasa i-cathodic disbondment, kuthathelwa ingqalelo ukusetyenziswa kwemibhobho emide. Iqondo lobushushu ke ngoko liseta iprojekthi yokukhutshwa kwecathodic yobushushu obuphezulu. Ukusuka kwi-index setting point view, kuyacaca ukuba i-anti-cathodic disbondment index ye-epoxy coating iphezulu, i-cathodic disbondment ephezulu yi-8.5mm kwiqondo lokushisa kwegumbi le-28d, kwaye ubuninzi be-cathodic disbondment kwiqondo lokushisa eliphezulu ngu-6.5mm kwi-48h. . Iimpawu zokugquma kwe-urea zikhululekile, i-12mm kunye ne-15m ngokulandelanayo.
