ʻO ka ʻokoʻa ma waena o ke alahaka galvanized a me ke alahaka galvanized wela

ʻO ke kiʻikuhi alahaka galvanized:

ʻO ke alahaka galvanized, i ʻike ʻia hoʻi he alahaka galvanized uila; ʻO ke alahaka galvanized i manaʻo nui ʻia he alahaka galvanized wela-dip, ʻo ka ʻoiaʻiʻo, he hewa ia, e like me ka paipu galvanized, ua māhele ʻia ke alahaka galvanized i ʻelua ʻano, ʻo ia hoʻi, ke galvanized anuanu (electric galvanized) a me ke galvanized wela-dip (wela-dip galvanized);

He maʻalahi ka hao a me ke kila i ka lewa, ka wai a i ʻole ka lepo, a i ʻole e hōʻino loa ʻia. ʻO ka pohō kila i kēlā me kēia makahiki i hana ʻia e ka palaho he 1/10 o ka hana kila holoʻokoʻa. Ma ka ʻaoʻao ʻē aʻe, i mea e loaʻa ai i nā huahana kila a me nā ʻāpana kahi hana kūikawā ma luna o ka ʻili, a hāʻawi i kona ʻili i ke ʻano hoʻonaninani i ka manawa like, no laila ua mālama pinepine ʻia ma ke ʻano o ka galvanizing uila.

1. Kumumanaʻo:

No ka mea, ʻaʻole maʻalahi ka hoʻololi ʻana o ka zinc i ka ea maloʻo, a i ka ea pulu, hiki i ka ʻili ke hana i kahi ʻili zinc carbonate kumu mānoanoa loa, hiki i kēia ʻili ke pale pono i loko mai ka pala. A i ka wā e hōʻino ʻia ai ka uhi no kekahi kumu a ʻaʻole nui loa ke kumu kila, hana ka zinc a me ka matrix kila i kahi microbattery, i lilo ai ka matrix kila i cathode a pale ʻia.

2. Nā ʻano hana:

1) Mānoanoa ka uhi zinc, maikaʻi ke crystallization, like a ʻaʻohe pores, a maikaʻi ke kūpaʻa ʻana i ka corrosion;

2) ʻO ka papa zinc i loaʻa ma ka electroplating he maʻemaʻe a palaho mālie i ka noe waikawa a me ka alkali, hiki ke pale pono i ka matrix kila;

3) ʻO ka uhi zinc i hoʻokumu ʻia e ka passivation chromic acid keʻokeʻo, kala, ʻōmaʻomaʻo koa, nani, loaʻa kahi mea hoʻonaninani;

4) No ka mea he ductility maikaʻi ka uhi zinc, hiki ke hoʻopau anu, ʻōwili, kūlou a me nā hana ʻē aʻe me ka ʻole o ka hōʻino ʻana i ka uhi.

3. Ka laulā o ka noi:

Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana, pili ka ʻoihana electroplating i nā kahua ākea aʻe. I kēia manawa, ua hoʻohana ʻia ka galvanizing ma nā keʻena hana a me nā keʻena noiʻi o ka hoʻokele waiwai aupuni. No ka laʻana, ʻo ka hana mīkini, nā mea uila, nā mea hana pololei, ka ʻoihana kemika, ka ʻoihana māmā, ka halihali, nā mea kaua, ka aerospace, ka ikehu atomika, a pēlā aku, he mea nui loa ia i ka hoʻokele waiwai aupuni.

Alahaka galvanized hoʻoluʻu wela(alahaka zinc luʻu wela)

1, wehewehe ʻana o ka zinc hoʻoluʻu wela:

ʻO ka zinc hoʻoluʻu wela kekahi o nā ʻano hana uhi maikaʻi loa no ka pale ʻana i ke kila kila. Aia ia i ke ʻano wai o ka zinc, ma hope o ka hana kino a me ka kemika paʻakikī, ʻaʻole wale ma ka papa kila kila mānoanoa zinc maʻemaʻe, akā hana pū kekahi i kahi papa zinc-hao. ʻAʻole wale kēia ʻano hana uhi i nā ʻano o ke kūpaʻa ʻana i ka pala o ka galvanizing, akā loaʻa pū kekahi i ka papa zinc-hao. Loaʻa iā ia kahi kūpaʻa ikaika i hiki ʻole ke hoʻohālikelike ʻia me ka galvanizing. No laila, kūpono loa kēia ʻano hana uhi no nā ʻano waikawa ikaika a pau, ka noe alkali a me nā wahi ʻino ikaika ʻē aʻe.

2. Kumumanaʻo:

Hoʻokumu ʻia ka papa zinc hoʻoluʻu wela i ʻekolu mau ʻanuʻu ma lalo o ke wai wela kiʻekiʻe:

1) Hoʻoheheʻe ʻia ka ʻili kumu hao e ka hopena zinc e hana i kahi papa pae zinc-hao;

2) Hoʻolaha hou aku nā iona zinc i loko o ka papa alloy i ka matrix e hana i kahi papa zinc-iron miscible;

3) Hoʻopuni ka ʻili o ka papa metala i ka papa zinc.

3. Nā ʻano hana:

(1) Me kahi papa zinc maʻemaʻe mānoanoa e uhi ana i ka ʻili o ke kila, hiki iā ia ke pale aku i ka matrix kila a me kekahi hoʻopili ʻana i ka hopena corrosion, e pale i ka matrix kila mai ka corrosion. I ka lewa holoʻokoʻa, ʻo ka ʻili o ka papa zinc e hana i kahi ʻili papa zinc oxide lahilahi a mānoanoa, he paʻakikī ke hoʻoheheʻe ʻia i ka wai, no laila ke pāʻani nei i kahi kuleana pale ma ka matrix kila. Inā zinc oxide a me nā ʻāpana ʻē aʻe i ka lewa e hana i ka paʻakai zinc insoluble, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion.

(2) Aia ka papa hao - zinc alloy, paʻa, i ka lewa pīpī paʻakai kai a me ka lewa ʻoihana e kūʻē i ka palaho;

(3) Ma muli o ka hui paʻa, hiki ke hui pū ʻia ka zinc-hao, me ke kūpaʻa ikaika i ka ʻaʻahu ʻana;

(4) No ka mea he maikaʻi ka ductility o ka zinc, ua paʻa pono kona papa alloy a me ke kumu kila, no laila hiki i nā ʻāpana plating wela ke hoʻopaʻa anu, ʻōwili, huki, kūlou a me nā ʻano ʻē aʻe me ka ʻole o ka hōʻino ʻana i ka uhi;

(5) Ma hope o ka hoʻomehana ʻana o nā ʻāpana kūkulu kila, ua like ia me kahi hana hoʻoheheʻe hoʻokahi, hiki ke hoʻomaikaʻi maikaʻi i nā waiwai mechanical o ka matrix kila, hoʻopau i ke kaumaha i ka wā o ke kūkulu ʻana a me ka hoʻopili ʻana o nā ʻāpana kila, a kūpono i ka hoʻohuli ʻana o nā ʻāpana kūkulu kila.

(6) He ʻālohilohi a nani hoʻi ka ʻili o nā mea pono ma hope o ka hoʻomehana ʻana i ka galvanizing wela.

(7) ʻO ka papa zinc maʻemaʻe ka papa plastik loa o ka papa galvanized hoʻoluʻu wela, kokoke kona mau waiwai i ka zinc maʻemaʻe, ductility, no laila he palupalu.

4. Ka laulā o ka noi:

Hoʻonui ʻia ka hoʻohana ʻana o ka galvanizing wela me ka hoʻomohala ʻana o ka ʻoihana a me ka mahiʻai. No laila, ʻo nā huahana galvanized wela i ka ʻoihana (e like me nā lako kemika, ka hana ʻaila, ka ʻimi ʻana i ke kai, ka hoʻolālā metala, ka hoʻoili mana, ke kūkulu moku, a pēlā aku), ka mahiʻai (e like me: ka irrigation, ka hale ʻōmaʻomaʻo), ke kūkulu ʻana (e like me: ka hoʻoili wai a me ke kinoea, ka uhi uea, ka scaffolding, ka hale noho, nā alahaka, ka halihali, a pēlā aku, ua hoʻohana nui ʻia i nā makahiki i hala iho nei. Hoʻohana nui ʻia nā huahana galvanized wela ma muli o ko lākou helehelena nani a me ke kūpaʻa maikaʻi i ka palaho.

ʻElua, ka ʻokoʻa ma waenaalahaka pīpīa mealahaka galvanized

ʻOkoʻa wale ke kaʻina hana o ke alahaka pīpī a me ke alahaka galvanized, like nā kikoʻī, nā kumu hoʻohālike, ke ʻano a me ke kūkulu ʻana o ke alahaka.

ʻO ka ʻokoʻa o ke kaʻina hana ma waena o ke alahaka pīpī a me ke alahaka galvanized:

ʻo ka mea mua loa,alahaka galvanizeda no ke alahaka ʻūlū palakika ke alahaka uwea metala, hana ʻia ke alahaka galvanized i ka papa kila galvanized, manaʻoʻiʻo wau ʻaʻohe pono e wehewehe nui, a hoʻohana ʻia ke alahaka ʻūlū palakika e hana i kahi papa o ka papa ʻūlū electrostatic ma luna o ka ʻili o ke alahaka galvanized, no laila ua kapa ʻia ʻo ia he alahaka ʻūlū palakika, ʻo ka hoʻomaopopo maʻalahi ʻo ke alahaka ʻūlū palakika ka mana hoʻonui o ke alahaka galvanized, ʻoi aku ka ikaika o ke kūpaʻa ʻana i ka corrosion.

Inā makemake ʻoe i kēia huahana, hiki iā ʻoe ke kaomi i ke kihi ʻākau ma lalo, e hoʻokaʻaʻike aku mākou iā ʻoe i ka wā hikiwawe loa.
