ʻO ke ʻano hoʻohui o ka paipu ahi: ke kaula, ka ʻāʻī, ka flange, a me nā mea ʻē aʻe. ʻO ka paipu kila epoxy composite i loko a me waho no ka pale ʻana i ke ahi he mea hoʻololi koʻikoʻi anti-corrosion epoxy resin pauka, a ʻoi aku ka maikaʻi o ke kūpaʻa kino. Hoʻoponopono maoli ia i nā pilikia he nui e like me ka corrosion o ka lepo a me ka pale ʻana o ka paia o loko o nā huahana like ma hope o ka hoʻohana lōʻihi ʻana, i mea e pale aku ai i ka blockage kūloko e pili ana i ka hoʻohana ʻana, i mea e hoʻomaikaʻi maikaʻi ai i ke ola lawelawe o nā paipu kaua ahi kūikawā. Ma muli o ka hoʻohui ʻana o nā mea pale ahi i loko o nā mea uhi, ua hoʻomaikaʻi ʻia ka pale wela o ka huahana i hoʻohālikelike ʻia me nā huahana like ʻole. No laila, ʻaʻole ia e pili 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. ʻulaʻula ke kala.

ʻO kā mākou hale hana kūikawā i ka hana ʻana i ka paipu ahi, ka paipu kila galvanized, ka paipu hoʻoheheʻe pauka, ka paipu hoʻoheheʻe pauka a me ka paipu kila 6-iniha. Noi: lako wai ahi, lako kinoea a me ka ʻōnaehana pipeline transport medium. Ua hala ka maikaʻi o ka huahana i nā kuʻuna a hala i nā hoʻokolohua he nui ma mua o ka haʻalele ʻana i ka hale hana. E hoʻokō me nā kūlana maikaʻi o ka ʻāina a me ka honua.

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

(2) ʻO ka uhi ʻana o ka paipu ahi i uhi ʻia i ka plastik e hoʻohana i ka resin epoxy, nona ka adhesion ikaika. Epoxy resin curing system loaʻa i ka hui epoxy, hydroxyl group, ether bond, amine bond, ester bond a me nā hui polar ʻē aʻe me ka hana nui, e hāʻawi ana i nā huahana epoxy cured adhesion maikaʻi loa i ka metala, keramika, aniani, kekona, lāʻau a me nā mea ʻē aʻe.

(3) Hoʻemi liʻiliʻi hoʻōla. ʻO ka maʻamau 1% ~ 2%. ʻO ia kekahi o nā ʻano me ka liʻiliʻi liʻiliʻi liʻiliʻi liʻiliʻi ma waena o nā resins thermosetting (phenolic resin he 8% ~ 10%; unsaturated polyester resin he 4% ~ 6%; silicone resin he 4% ~ 8%). He liʻiliʻi loa ka helu hoʻonui laina, ma ke ʻano he 6 × 10-5/℃. No laila, hoʻololi liʻiliʻi ka leo ma hope o ka hoʻōla ʻana.

(4) Maikaʻi ka hana. ʻAʻole hoʻopuka ka epoxy resin i nā volatiles haʻahaʻa haʻahaʻa i ka wā o ka mālama ʻana, 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 lapaʻau like ʻole no ka hana ʻana i nā mea hoʻonaninani pili i ke kaiapuni e like me ka solvent-free, solid solid, pauka a me nā uhi wai.

(5) Hoʻopili uila maikaʻi loa. ʻO ka resin epoxy kahi resin thermosetting me nā waiwai antistatic maikaʻi.

(6) Ke kūpaʻa maikaʻi a me ke kūpaʻa kemika maikaʻi loa. ʻO ka resin epoxy me ka ʻole o ka alkali, ka paʻakai a me nā mea haumia ʻē aʻe ʻaʻole maʻalahi e hōʻino. ʻOiai ka lōʻihi o ka mālama pono ʻana (i hoʻopaʻa ʻia, ʻaʻohe wai a me ke kiʻekiʻe o ka mahana), ʻo 1 makahiki ka manawa mālama. Ma hope o ka lā pau, inā kūpono ka nānā ʻana, hiki ke hoʻohana ʻia. Epoxy curing compound he maikai loa kemika. ʻOi aku ka maikaʻi o kona pale ʻana i ka alkali, ka waikawa, ka paʻakai a me nā mea ʻē aʻe ma mua o ka resin polyester unsaturated, resin phenolic a me nā resins thermosetting ʻē aʻe. No laila, hoʻohana nui ʻia ka epoxy resin ma ke ʻano he anti-corrosion primer. Ma muli o ka ho'ōla epoxy resin he ʻekolu-dimensional network structure a hiki ke pale aku i ka impregnation o ka aila, hoʻohana nui ʻia i loko o ka pā o loko o nā pahu aila, nā pahu aila a me nā mokulele.

Kii 1 paipu ahi

Kiʻi 1 paipu ahi (5 ʻāpana)

(7) ʻO ke kūpaʻa wela o ka epoxy curing compound he 80 ~ 100 ℃. Hiki i nā ʻano wela wela o ka epoxy resin ke hiki i 200 ℃ a i ʻole.
