Uea nikala maʻemaʻe, ʻoi aku ka lahilahi o ke anawaena o ke kaula he 0.025 mm

Uea Nickel Lahilahi Loa Nickel 0.025mm

Loaʻa i ka nickel ke kūpaʻa kemika kiʻekiʻe a me ke kūpaʻa maikaʻi i ka palaho ma nā ʻano media he nui. ʻO kona kūlana electrode maʻamau he -0.25V, ʻoi aku ka maikaʻi ma mua o ka hao a me ka maikaʻi ʻole ma mua o ke keleawe. Hōʻike ʻo Nickel i ke kūpaʻa maikaʻi i ka palaho i ka loaʻa ʻole o ka oxygen i hoʻoheheʻe ʻia i nā waiwai dilute non-oxidized (e laʻa, HCU, H2SO4), ʻoi aku hoʻi i nā hopena neutral a me alkaline. ʻO kēia no ka mea hiki i ka nickel ke passivate, e hana ana i kahi kiʻi pale mānoanoa ma luna o ka ʻili, kahi e pale ai i ka nickel mai ka oxidation hou aʻe. Nā kahua noi nui: ʻenekinia kemika a me ke kemika, nā ʻāpana anti-wet corrosion generator (mea hoʻomehana wai komo a me ka paipu mahu), nā lako hoʻomalu haumia (nā lako wehe sulfur gas ʻōpala), etc.

Hoʻohana nui ʻia ka Pure Nickel Wire no ka hana ʻana i nā pilina no nā mea hoʻomehana. Hiki iā ia ke kū a hiki i ka palena kiʻekiʻe o 350 degere C. Loaʻa ka Pure Nickel Wire Mesh i nā anawaena ākea mai 0.030 a 0.500 mm ma ke ʻano he uea ʻōlohelohe. Hana ʻia ka Pure Nickel Wire me ke kila kalapona haʻahaʻa a me ka pakeneka o 99.5%.nikala maʻemaʻe.
ʻO ke ʻano o Nickel 201 e like me kēia ma lalo nei:
Kūpaʻa loa i nā kemika hoʻemi like ʻole
Ke kūpaʻa maikaʻi loa i nā alkalis caustic
ʻO ke alakaʻi uila kiʻekiʻe
ʻO ke kūpaʻa maikaʻi loa i ka wai i hoʻoheheʻe ʻia a me nā wai kūlohelohe
Ke kū'ē i nā hopena paʻakai kūlike a me ka alkaline
Ke kūpaʻa maikaʻi loa i ka fluorine maloʻo
Hoʻohana nui ʻia e lawelawe i ka soda caustic
Nā waiwai wela, uila a me ka magnetostrictive maikaʻi
Hāʻawi i kekahi kū'ē i nā waikawa hydrochloric a me sulfuric ma nā mahana a me nā ʻano haʻahaʻa

Kahua noi Nickel 201:
Nā lako hana meaʻai
ʻEnekinia moana a me ke kai
Hana paʻakai
Nā lako hana hoʻomaʻamaʻa caustic
Hana ʻana a me ka lawelawe ʻana i ka sodium hydroxide, ʻoiai ma nā mahana ma luna o 300°
