Kiʻekiʻe Fiberglass Kūʻai -Paʻa Paʻi

ʻO nā papa anti-corrosion ʻo FRP -ʻo ia nā mea i hoʻonohonoho pono ʻia e hāʻawi i ke kūpaʻa kemika ʻoi aku ka maikaʻi a he mea koʻikoʻi ia i nā kūlana ʻoihana paʻakikī a me ke kaiapuni. Hoʻokumu ʻia me nā matrices resin -kiʻekiʻe a me nā mea hoʻoikaika fiber aniani, ua hoʻohui kēia mau papa i ka ikaika mechanical me ke kūpaʻa ʻino maikaʻi loa, e hāʻawi ana i kahi ʻokoʻa paʻa i nā mea kuʻuna e like me ke metala, ka lāʻau, a i ʻole ke kaʻa i loko o nā wahi ʻino.

ʻEkolu mau ʻāpana kiʻi o ka ʻōnaehana kumu o nā papa anti-corrosion FRP: ʻo ka ʻaʻahu gel pale pale, ka papa hoʻoikaika i ka fiber aniani, a me ka papa resin backing. ʻO ka papa lole gel, i hana maʻamau ʻia me ka polyester unsaturated a i ʻole ka vinyl ester resin, e hana i ka pale waho loa, e hāʻawi ana i kahi ʻili maʻemaʻe, pore -ʻole e kūʻē i ke komo ʻana i nā mea kemika a me ka hōʻino ʻana o UV. Ma lalo o ia mea, ua hoʻonohonoho ʻia nā mea hoʻoikaika kino aniani ma ke ʻano o nā moena a i ʻole nā ​​lole i ulana ʻia, e hāʻawi ana i ka ikaika mechanical i ka papa a me ka hōʻoia ʻana hiki iā ia ke pale i nā ukana a me nā hopena. ʻO ka resin backing, pinepine me nā mea hoʻopiʻi corrosion i hoʻohui ʻia, hoʻonui i ka lōʻihi holoʻokoʻa o ka papa a me ka pili ʻana ma waena o nā papa. Hiki i nā mea hana ke hoʻonohonoho i ka mānoanoa o kēlā me kēia papa (mai ka 2 mm a hiki i ka 15 mm) e like me nā koi noi kikoʻī, e loaʻa ana kahi kaulike ma waena o ke kaumaha a me ka hana.

ʻO kekahi o nā hiʻohiʻona kamahaʻo o ka fiberglass composite anti-corrosion plate, ʻo ia ko lākou kūpaʻa kemika nui. Hōʻike lākou i ka hoʻomanawanui maikaʻi loa i nā mea corrosive like ʻole, e like me nā waikawa (e like me ka sulfuric acid a me ka hydrochloric acid), nā kumu (sodium hydroxide, ka wai amonia), nā paʻakai, nā mea hoʻoheheʻe, a me nā wai ʻona ʻoihana. ʻAʻole e like me nā pā metala e ʻāhuʻi a ʻino paha i ka wā e ʻike ʻia ai ia mau mea kemika, hiki i nā pā fiberglass ke mālama i ko lākou kūpaʻa ʻana ma hope o ka hoʻopili lōʻihi ʻana. Ua hōʻoia ʻia kēia kūpaʻa kemika ma o nā hoʻāʻo koʻikoʻi, e like me ka hoʻāʻo ʻana i ka tolerance kemika e like me ka maʻamau ASTM D543, kahi i hoʻopaʻa ʻia ai nā laʻana i nā hopena like ʻole a hiki i 30 a 90 mau lā, me ka liʻiliʻi o ke kaumaha.<1%) and no obvious signs of degradation, such as cracking, bubbling, or discoloration.

Ma waho a'e o ke kū'ē kemika, loa'a nō ho'i nā 'ano mekini maika'i loa nā pāpa'i anti-corrosion composite fiberglass. Loaʻa iā lākou ka ikaika tensile kiʻekiʻe (50 - 150 megapascals) a me ka ikaika piʻo (80 - 200 megapascals), e like me kekahi mau metala, akā me ke kaumaha ʻoi aku ka māmā (ka mānoanoa o 1.5 - 2.0 grams no ke kenimika cubic, aʻo ke kila he 7.8 grams no ke kenimika cubic). ʻO kēia hiʻohiʻona māmā e hōʻemi ana i nā kumukūʻai o ka lawe ʻana a me ka hoʻokomo ʻana, e maʻalahi i ka hoʻokele ʻia i nā papahana nui-nui. ʻOi aku ko lākou pale ʻana i ka hopena (15 - 30 kilojoules no kēlā me kēia mika square) ma mua o nā mea palupalu e like me ka seramika a i ʻole ke aniani, e hōʻoia ana e hiki iā lākou ke kū i ka hui ʻana i manaʻo ʻole ʻia a i ʻole nā ​​kūlana ʻino e like me ka huahekili.
