Nnwale ịgba nnu nke mkpuchi

A na-enyocha nguzogide corrosion nke mkpuchi ahụ site na ikpughe mkpuchi ahụ na ikuku nnu nnu na-emepụta site na ịgbasa 5wt% mmiri mmiri NaCl ngwọta na 35 ± 2 Celsius C maka 3000 h dị ka ISO 14655: 1999 nkọwapụta. Mgbe e wepụsịrị ya na ọnụ ụlọ nnu nnu, a na-asacha ihe atụ niile na mmiri mmiri na-ekpo ọkụ iji wepụ ihe ọ bụla fọdụrụnụ, a na-ahụ mmebi nke mkpuchi. Enwere ike ịhụ ya site na Fig.10, mgbe mkpuchi jupụtara na CTBNEP prepolymers (Fig.10b), ọ dịghị ihe àmà nke nchara, na ihe atụ ndị na-enweghị ezumike, na-egosi nkwụsị nke corrosion nke mkpuchi filled na CTBN EP prepolymers. nwere ike imezu ihe achọrọ nke ọkọlọtọ.

The corrosion eguzogide nke organic mkpuchi na-enweghị ntụpọ na-adabere tumadi ya mgbochi Njirimara, ntụgharị, otú o ebelata mgbasa nke mmiri na corrosive ion site na fim.
