1, kāpīpī i ka zinc anti-corrosion coating
Ma hope o ka hoʻomaʻamaʻa mua ʻana i ka paipu hao nodular, hoʻoheheʻe ʻia ke kino o ka paipu me ke kiʻekiʻe o ka hoʻoheheʻe metala zinc solution ke piʻi ka mahana ma kahi o 600 degere Celsius.ʻO ka uhi ʻana o ka zinc ma hope o ka pīpī ʻana he adhesion maikaʻi, ʻaʻole maʻalahi e hāʻule, a he hana anticorrosion maikaʻi.
2, asphalt pena anti-corrosion uhi
ʻO ka uhi ʻana i ka asphalt ka mālama anticorrosion waho o ka wai maloʻo a me ke kino hoʻolako kino kino.Ma mua o ka pulupulu ʻana, ua hoʻomaʻamaʻa ʻia ke kino o ka pahu hao nodular i 80-100 degere a laila e hoʻopuʻi ʻia.Ma hope o ka hoʻomehana ʻana, hoʻomaikaʻi ka pipi ʻana i ka pili o ka papa asphalt a hiki ke hoʻomaloʻo koke ʻia.
3, ʻo ka līlū sima + ka uhi anti-corrosion kūikawā
He kūpono kēia ʻano anticorrosive kūloko no ka lawe ʻana i ka wai maloʻo, a me ka hoʻokuʻu ʻana o ka pipeline kino mokuʻāina, ka wai a me ka hoʻokuʻu ʻana o ka wai me nā ʻāpana ʻokoʻa o loko, hiki ke hoʻomaikaʻi i ke kūpaʻa ʻana o ka pā paipu hao ductile, kaʻawale. ka wai a me ka papa hao, i ʻole e hoʻohaumia i ka wai.
3, ka lanahu epoxy asphalt anti-corrosion coating
He kūpono ka uhi ʻana o ka coal tar epoxy no ka lako wai a me nā paipu wai.He ʻāpana ʻelua ʻāpana me ka hoʻopili kiʻekiʻe a me ka ʻili maʻalahi.
4, ʻaihue epoxy seramika i hoʻopaʻa ʻia me ka uhi anticorrosive
He kūpono ka epoxy ceramic lining no nā paipu me nā koi kiʻekiʻe no ka lako wai, ka aila a me nā wai kemika kūikawā.ʻO ka lining ceramic epoxy he adhesion kiʻekiʻe a me ka māmā māmā, a me ka liʻiliʻi liʻiliʻi o ka wai.He mea hoʻopili maikaʻi loa ia i ka anti-corrosion.Akā, ma ke kaʻina hana maloʻo he mea kiʻekiʻe, kiʻekiʻe ke kumukūʻai, no laila aia kekahi mau palena i ka hoʻohana.
5, aluminate sima ka uhi a me ka sulfate sima anticorrosive uhi
He kūpono kēia mau ʻāpana sima kūikawā ʻelua no ka anticorrosion kūloko o nā paipu hao nodular i hoʻohana ʻia i nā pipeline wai e hoʻomaikaʻi i ke kūpaʻa ʻana o ka waika a me nā mea alkali i loko o ka wai.
6, polyurethane anticorrosive uhi
Kapa ʻia ʻo Polyurethane he polyurethane, ʻo ia ke kaulahao nui i loaʻa i ka hui carbamate mau o nā pūhui macromolecular.Hoʻokumu ʻia ia me ka diisocyanate organik a i ʻole polyisocyanate a me ka dihydroxyl a i ʻole polyhydroxyl compound copolymerization.ʻAʻole wale ʻo ia wale nō ka maikaʻi o ka pale ʻana i ka ʻaʻahu, ke kūpaʻa hopena, ke kūʻē ʻana, ka pale uv a me ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa, me ka ikaika kiʻekiʻe, ke kūpaʻa ʻaʻahu kiʻekiʻe a me ke kūpaʻa solvent.He pipiʻi hoʻi ka hana ʻana o ka uhi.
