ʻO ka hoʻāʻo ʻana a me ka hoʻopili ʻana o ka pauka FBE

Pili o ʻO ka uhi pauda FBE

Hoʻohana nui ʻia kahi hōʻike kīʻaha e hoʻoholo ai i ka pili ʻana o ka uhi ʻana o ka pauka FBE, a hōʻike ʻo Fig.7 i ke kumu hoʻāʻo o ka mea hōʻike kīʻaha. ʻO ke poʻo o ka mea hōʻike kīʻaha he spherical, e koi ana i ke kua o nā paneli i uhi ʻia e hoʻāʻo ai inā ua haki a hoʻokaʻawale paha ke kiʻi maikaʻi mai ka substrate. Fig.8 he hopena ho'āʻo kīʻaha o ka uhi pauda epoxy. Hiki ke ʻike ʻia he mau māwae liʻiliʻi ka ʻike ʻia o ka pauka FBE i hoʻopiha ʻole ʻia me CTBN-EP prepolymers (Fig. 8(1)), aʻo nā uhi i hoʻopiha ʻia me CTBN-EP prepolymers (Fig. 8(2-3)) ʻaʻohe māwae ʻike ʻia, e hōʻike ana i ka pili maikaʻi a me ka paʻakikī.

Kū'ē i nā ho'āʻo kūlou o ka pauka FBE

Hōʻike ka Fig.9 i ke kūʻē ʻana i nā hopena hōʻike hoʻāʻo ʻekolu ʻano o ka pauka FBE. ʻAʻole maikaʻi ke kūʻē ʻana i ke kuʻi ʻana o nā uhi pauka FBE me ka hoʻopiha ʻole ʻana me CTBN-EP prepolymers (Fig.9(1)), a ʻike ʻia kahi mea hoʻoheheʻe cohesive. Ke hoʻohui ʻia nā prepolymers CTBN-EP i loko o ka uhi pauda, ​​ʻoi aku ka maikaʻi o ke kūʻē ʻana i ka pelu ʻana o ka pauka FBE me ka hoʻonui ʻia o ka ʻike o CTBN-EP prepolymers (Fig.9(2-3)), a ʻaʻohe mea i ʻike ʻia. , e hōʻike ana i ke kūpaʻa kiʻekiʻe i ka piko.

Ho'āʻo paʻakai paʻakai o nā uhi

ʻIke ʻia ka pale ʻana o ka corrosion o nā uhi ma ka wehe ʻana i nā uhi i kahi ea paʻakai i hana ʻia e ka hoʻoheheʻe ʻia ʻana o 5wt% aqueous NaCl solution ma 35 ± 2 °C no 3000 h e like me ka ISO 14655:1999 kikoʻī. Ma hope o ka wehe ʻia ʻana mai ke keʻena puaʻa paʻakai, holoi ʻia nā mea hoʻohālike a pau me ka wai distilled e wehe i nā koena, ʻike ʻia ka corrosion o ka uhi. Hiki ke ʻike ʻia mai ka Fig.10, ma hope o ka hoʻopiha ʻia ʻana o nā uhi me nā CTBNEP prepolymers (Fig.10b), ʻaʻohe mea hōʻike o ka ʻōpala, a ʻaʻohe mea hoʻomaha hoʻomaha, e hōʻike ana i ke kūpaʻa corrosion o nā uhi i hoʻopiha ʻia me CTBN EP prepolymers. hiki ke hoʻokō i nā koi o ka maʻamau.

ʻO ka pale ʻana i ka corrosion o kahi uhi organik me nā kīnā ʻole e hilinaʻi nui ʻia ma kāna mau mea pale, ʻo ia hoʻi, pehea ia e hōʻemi ai i ka laha ʻana o ka wai a me nā ion corrosive ma o ke kiʻiʻoniʻoni. Ma waena o nā ʻāpana e hāʻawi i nā waiwai pale ʻo ia ka hoʻouka ʻana o ka substrate metala lalo. ʻO ka uhi ʻana ma kahi kokoke i ka ʻāina ākea e hana i kahi papa passivating ma ka substrate e pale ai i ka ʻino hou aʻe. No laila, hiki iā ia ke hopu i nā ion (ʻo Cl− paha) maʻalahi e hana i ka polymer doped.
