ʻAno hoʻohui o ka paipu ahi: kaula, ʻauwaha, flange, a pēlā aku. ʻO ka paipu kila epoxy composite kūloko a me waho no ka pale ahi he pauka resin epoxy anti-corrosion kaumaha i hoʻololi ʻia, nona ke kūpaʻa maikaʻi loa i ka pala kemika. Hoʻoponopono nui ia i nā pilikia he nui e like me ka pala o ka ʻili a me ka scaling o ka paia o loko o nā huahana like ma hope o ka hoʻohana lōʻihi, i mea e pale aku ai i ka poloka kūloko e pili ana i ka hoʻohana ʻana, i mea e hoʻomaikaʻi nui ai i ke ola lawelawe o nā paipu kinai ahi kūikawā. Ma muli o ka hoʻohui ʻana o nā mea pale ahi i nā mea uhi, ua hoʻomaikaʻi ʻia ke kūpaʻa wela o ka huahana i hoʻohālikelike ʻia me nā huahana like ʻē aʻe. No laila, ʻaʻole ia e hoʻopilikia i ka hoʻohana ʻana i ka wā e piʻi nui ai ka mahana ambient. ʻOi aku ka maikaʻi o ke ola lawelawe a me ka hana o nā paipu ahi i uhi ʻia i loko a me waho ma mua o nā paipu galvanized. He ʻulaʻula ke kala.

He loea kā mākou hale hana i ka hana ʻana i nā paipu ahi, nā paipu kila galvanized, nā paipu uhi pauka, nā paipu uhi pauka a me nā paipu kila 6-'īniha. Hoʻohana: hoʻolako wai ahi, hoʻolako kinoea a me ka ʻōnaehana paipu halihali waena huʻa. Ua hala ka maikaʻi o ka huahana i nā dute a hala i nā hoʻāʻo he nui ma mua o ka haʻalele ʻana i ka hale hana. E kūlike me nā kūlana maikaʻi o ka ʻāina a me ka honua.

(1) Nā waiwai mechanical kiʻekiʻe. Loaʻa i ka resin Epoxy ka cohesion ikaika a me ka hoʻonohonoho molekala paʻa, no laila ʻoi aku ke kiʻekiʻe o kona mau waiwai mechanical ma mua o nā resins thermosetting maʻamau e like me ka resin phenolic a me ka polyester unsaturated.

(2) Hoʻohana ka ʻili o ka paipu ahi i uhi ʻia i ka plastik i ka resin epoxy, nona ka hoʻopili ikaika. Loaʻa i ka ʻōnaehana hoʻōla resin Epoxy ka hui epoxy, ka hui hydroxyl, ka pilina ether, ka pilina amine, ka pilina ester a me nā hui polar ʻē aʻe me ka hana nui, e hāʻawi ana i nā huahana epoxy i hoʻōla ʻia i ka hoʻopili maikaʻi loa i ka metala, keramika, aniani, sima, lāʻau a me nā substrates polar ʻē aʻe.

(3) Ka emi iki ʻana o ka hoʻōla ʻana. Ma ke ʻano laulā 1% ~ 2%. ʻO ia kekahi o nā ʻano me ka emi iki ʻana o ka hoʻōla ʻana ma waena o nā resins thermosetting (ʻo ka resin phenolic he 8% ~ 10%; ʻo ka resin polyester unsaturated he 4% ~ 6%; ʻo ka resin silicone he 4% ~ 8%). He liʻiliʻi loa hoʻi ke koina hoʻonui linear, ma ke ʻano laulā 6 × 10-5/℃。 No laila, ʻaʻole nui ka loli o ka nui ma hope o ka hoʻōla ʻana.

(4) Hana maikaʻi. ʻAʻole hana ka resin epoxy i nā molekala haʻahaʻa i ka wā e hoʻōla ai, no laila hiki ke hana ʻia ma lalo o ke kaomi haʻahaʻa a i ʻole ke kaomi pili. Hiki iā ia ke hana pū me nā mea hoʻōla like ʻole e hana i nā uhi aloha kaiapuni e like me ka solvent-free, high solid, powder coatings a me nā uhi wai.

(5) Pale uila maikaʻi loa. He resin thermosetting ka resin Epoxy me nā waiwai antistatic maikaʻi.

(6) Paʻa maikaʻi a me ke kūpaʻa kemika maikaʻi loa. ʻAʻole maʻalahi ka palaho ʻana o ka resin epoxy me ka ʻole o ka alkali, ka paʻakai a me nā mea haumia ʻē aʻe. Inā mālama pono ʻia (sila ʻia, ʻaʻohe makū a me ke kiʻekiʻe o ka mahana), ʻo ka manawa mālama he 1 makahiki. Ma hope o ka lā pau, inā kūpono ka nānā ʻana, hiki nō ke hoʻohana ʻia. Loaʻa i ka hui hoʻōla Epoxy ka paʻa kemika maikaʻi loa. ʻOi aku ka maikaʻi o kona kūpaʻa i ka palaho i ka alkali, ka waikawa, ka paʻakai a me nā mea ʻē aʻe ma mua o ka resin polyester unsaturated, phenolic resin a me nā resins thermosetting ʻē aʻe. No laila, hoʻohana nui ʻia ka resin epoxy ma ke ʻano he primer anti-corrosion. No ka mea, he ʻekolu-dimensional ka ʻōnaehana pūnaewele o ka resin epoxy i hoʻōla ʻia a hiki ke kū i ka impregnation o ka ʻaila, hoʻohana nui ʻia ia i loko o ka paia o loko o nā pahu ʻaila, nā moku ʻaila a me nā mokulele.

(7) ʻO ke kūpaʻa wela o ka hui epoxy curing maʻamau he 80 ~ 100 ℃. Hiki i nā ʻano epoxy resin kūpaʻa wela ke hiki i 200 ℃ a ʻoi aku paha.
