ʻO Hastelloy B-3 alloy he lālā hou ia o ka ʻohana o nā nickel-molybdenum alloys, he kūpaʻa maikaʻi loa ka corrosion i ka waika hydrochloric i kēlā me kēia mahana a me ka ʻike.I ka manawa like, loaʻa iā ia ke kūpaʻa corrosion maikaʻi i ka sulfuric acid, acetic acid, formic acid, phosphoric acid a me nā mea ʻē aʻe non-oxidizing media.Eia kekahi, ma muli o ka hoʻoponopono ʻana o kāna ʻano kemika, ua hoʻomaikaʻi maikaʻi ʻia kona kūpaʻa wela i ka hoʻohālikelike ʻia me ka alloy Hastelloy B-2 mua.He kiʻekiʻe ke kūpaʻa ʻana o Hastelloy B-3 i ka pitting corrosion, stress corrosion cracking, pahi ʻino a me ka corrosion i ka wahi wela o ka kuʻi ʻana.
ʻO Hastelloy B-3 alloy kekahi nickel-based advanced alloy after B-2 alloy.Loaʻa iā ia kahi mea hoʻohui kemika i hoʻolālā ʻia e hoʻokō i kahi kiʻekiʻe kiʻekiʻe o ke kūpaʻa wela ma mua o nā alloys Hastelloy ʻē aʻe e like me B-2 a he kūpaʻa maikaʻi loa i ka pitting, crevice corrosion, stress corrosion, knife corrosion a me nā hopena wela e hiki ke corrode.Ma muli o ka hoʻomaikaʻi maikaʻi ʻana o ka wela o ka hui B-3, ua hoʻemi ʻia nā pilikia i loaʻa i ka hana ʻana i nā ʻāpana e like me ka alloy B-2 ma muli o ka emi ʻana o ka ua o nā pae waena pōʻino i ke ʻano huila B-3.Hāʻawi kēia i ka ductility kiʻekiʻe ma mua o nā ʻāpana B-2 ma lalo o nā kūlana kaʻa uila e like me ka hoʻolei ʻana a me ka wili.
ʻO kēia huila nickel-molybdenum he kūpaʻa maikaʻi loa ia i nā ʻāpana a pau o ka waika hydrochloric ma ka ambient i nā mahana kiʻekiʻe.He kūpaʻa nō hoʻi ia i ka sulfuric, acetic, formic a me phosphoric acids a me nā mea hoʻolaha non-oxidizing ʻē aʻe.He kūʻē maikaʻi loa ʻo B-3 i ka pitting a me ke koʻikoʻi i ka pohā ʻino.
Mea Pono o B-3 Alloy
Kū'ē maikaʻi i ka waika hydrochloric ma nā ʻano a me nā mahana a pau, ke kū'ē i ka sulfuric, acetic, formic a me phosphoric acids a me nā mea hoʻoheheʻe ʻole ʻē aʻe.
Hoʻohana maʻamau o Hastelloy B3
Hoʻohana maʻamau ʻia nā alloys Hastelloy B i loko o nā wahi corrosive koʻikoʻi a ikaika, a hoʻohana nui ʻia i nā kemika, petrochemical, ikehu a me ka pollution control mahina, ʻoi aku hoʻi i nā ʻoihana e like me ka sulfuric acid, hydrochloric acid, phosphoric acid, a me ka acetic acid, e like me ka distillation. a me ka nui o ka waika hydrochloric;kaomi haʻahaʻa Oxylated acetic acid (HAC);halogenated butyl rubber (HIIR);polyurethane maka a me ka ethylbenzene alkylation hana a me nā mea hana ʻē aʻe.
Ma muli o ke kumu kūʻai kiʻekiʻe, ʻoi aku ka nui o ka noi ʻana o Hastelloy B series alloys, ka mea nui i ka hana ʻana o ka acetic acid (oxo synthesis) a me kekahi mau ʻōnaehana hoʻihoʻi sulfuric acid, e like me nā evaporators a me ka dilute sulfuric acid storage tank i ka acetic acid engineering.
