Kwinkqubo yemibhobho yamanzi engaphantsi komhlaba, ukuqina kunye nokumelana nokugqwala kugqiba ngokuthe ngqo ubomi bobunjineli. Imibhobho eguqulweyo ene-polypropylene esiyiqalisileyo, enobuchwepheshe obuphambili bokuwelda i-spiral submerged arc, iye yaba sisisombululo esithandwayo sokuthuthwa kwamanzi angaphantsi komhlaba, enomgangatho ogqwesileyo kunye nokuqina okuhlala ixesha elide, ihlangabezana ngokugqibeleleyo nemigangatho ephezulu yokunikezelwa kwamanzi angaphantsi komhlaba kwaye ifanelekile kwiimeko ezahlukeneyo zokusetyenziswa. Kwaye isitshixo sokuphucula ukusebenza kwale mveliso iphambili kukongezaUgqubuthelo lwe-FBE ARO.
Umbhobho wokugquma we-3LPE (polyethylene enamaleko amathathu) ngokwawo unezakhono ezisisiseko zokulwa nokugqwala kunye nokukhusela oomatshini, kodwa imeko-bume engaphantsi komhlaba iyinkimbinkimbi, kunye nokungqubana kwamatye ngexesha lokuthuthwa nokufakwa, impembelelo yokubuyela umva, kunye neendaba ezirhabaxa ezifana nee-asidi, ii-alkalis, kunye neetyuwa emhlabeni, ezinokuthi zonakalise i-polyethylene yangaphandle kwaye zichaphazele ukuthembeka kombhobho. Ingubo ye-FBE ARO, njengenkqubo yokukhusela eneziphumo ezimbini edibanisa i-epoxy eboshiweyo (FBE) kunye nengubo yangaphandle enganyangekiyo (ARO), igcwalisa ngokuchanekileyo esi sikhewu.
IUkwaleka kwe-FBEibotshelelwe ngokusondeleyo kwi-substrate yombhobho wentsimbi, yenza umgca wokuqala womqobo wokulwa nokugqwala, othintela ngempumelelo ukungena komswakama kunye nezinto ezirhabaxa; i-ARO coating inika ukumelana nokugqwala okunamandla kakhulu kunye nokuxhathisa impembelelo, ikhusela umbhobho ekonakaleni ngokomzimba ngexesha lokufakwa kunye nokusetyenziswa ixesha elide. Ukusebenzisana kwezi zimbini akuphindi nje kabini ukusebenza kokulwa nokugqwala kunye nokulwa nokugqwala kombhobho ogqunywe nge-3LPE, kodwa ikwahlangabezana nemigangatho engqongqo yokunikezelwa kwamanzi angaphantsi komhlaba, yandisa ubomi bombhobho.
Lo mbhobho ugqunywe nge-polypropylene ene-3LPE egqunywe nge-FBE ARO coating udibanisa amandla olwakhiwo kunye nokhuseleko oluphindwe kabini ngokugqibeleleyo, ubonelela ngeziqinisekiso ezithembekileyo zokubonelela ngamanzi kamasipala, ukuthuthwa kwamanzi angaphantsi komhlaba kwimizi-mveliso kunye nezinye iimeko, kwaye uba sisisombululo esiphezulu kwiinkqubo zemibhobho yamanzi angaphantsi komhlaba.
