Nā Pōmaikaʻi a me ka Hoʻohālikelike Hoʻohālikelike Hoʻohālikelike o nā Kaʻina Hana Lapaʻau Nui no nā mea hoʻopili 

I. ʻO nā kaʻina hana lapaʻau nui no nā mea paʻa a me kā lākou mau pono kumu

1. Electrogalvanizing (E komo pū me Blue-White Zinc a me kala Zinc)

ʻO ka Electrogalvanizing (cold galvanizing) kahi kaʻina e waiho ai i kahi ʻāpana zinc like ʻole ma luna o nā ʻili paʻa ma o ka electrolysis, loaʻa i nā ʻano like me ka zinc polū-keʻokeʻo a me ka zinc kala. ʻO ia ke ʻano lapaʻau haʻahaʻa haʻahaʻa i hoʻohana nui ʻia no nā mea hoʻopaʻa kālepa. ʻO kāna mau pōmaikaʻi koʻikoʻi ʻo ia ka ʻenehana makua, ke kumu kūʻai haʻahaʻa, ka mānoanoa o ka uhi ʻana (5-15μm), ka hoʻopau ʻana o ka ʻili kiʻekiʻe, a me nā koho kala he nui, e kūpono ana i nā koi i nā hiʻohiʻona anti-corrosion māmā i loko. No nā mea hoʻopaʻa wili liʻiliʻi (e laʻa, ma lalo o M8), ʻaʻole e ālai ka electrogalvanizing i nā milo a i ʻole nā ​​slot, e hāʻawi ana i nā hana hoʻohui maikaʻi loa, ka loaʻa ʻana o ka mākeke kiʻekiʻe, a me nā pōʻai pōkole.

Pono e hoʻomaopopo ʻia he pilikia ko ka electrogalvanizing i ka hydrogen embrittlement a pili wale i nā mea paʻa me ka paʻakikī ma lalo o HRC38. Eia kekahi, ʻoi aku ka haʻahaʻa o kāna hana anti-corrosion. ʻO ka lōʻihi o ka electrogalvanizing maʻamau ka neutral salt spray test (NSS) he 24-96 mau hola, hiki ke hoʻonui ʻia ma mua o 200 mau hola ma hope o ka mālama ʻana me nā sealants kūikawā, akā e hoʻonui ʻia ke kumukūʻai e 5-8 mau manawa e like me ia.

2. Non-Electrolytic Zinc Flake Coating (Dacromet/DACROMET)

ʻO Dacromet kahi ʻano uhi hou i haku ʻia me ka pauka zinc, ka pauka alumini, a me ka waikawa chromic, i hoʻokumu ʻia ma o ka uhi ʻana a me ka curing curing. ʻO ia ke kaʻina hana i makemake ʻia no ka wā lōʻihi anti-corrosion i loko o nā kaiapuni paʻakikī, me nā pōmaikaʻi koʻikoʻi: ʻaʻohe pilikia hydrogen embrittlement, kūpono ia no nā mea hoʻopaʻa ikaika kiʻekiʻe; ʻO ke kūpaʻa ʻino maikaʻi loa, me ka hoʻāʻo ʻana i ka paʻakai paʻakai kūʻokoʻa (NSS) lōʻihi o 500-800 mau hola no kahi papa hoʻokahi a me 1500-2000 mau hola no kahi papa pālua, me ke kūpaʻa mahana maikaʻi (lōʻihi ≤250 ℃); ka mana hoʻokō friction, e hōʻoia i ka paʻa ʻana o ka ikaika clamping no nā pili koʻikoʻi a kūpono i nā hiʻohiʻona me nā koi kiʻekiʻe no ka pili pono.

ʻO kona mau hemahema, ʻaʻole hiki ke hoʻololi i nā mea hoʻopaʻa liʻiliʻi ma lalo o M8 a i ʻole nā ​​mea hoʻopaʻa kaula i loko, no ka mea, hiki i ka uhi ke hoʻopili i ka hui; ka pae kumu kūʻai maʻamau, ka loaʻa ʻana o ka mākeke maʻamau, a me ka Dacromet kuʻuna he hexavalent chromium, no laila pono e mālama ʻia ka mālama ʻana i ke kaiapuni.

3. Wela-Dip Galvanizing

ʻO ka Hot-dip galvanizing kahi kaʻina hana no nā hiʻohiʻona anti-corrosion koʻikoʻi o waho, e hana ana i kahi uhi ma ka hoʻokomo ʻana i nā mea hoʻopaʻa i loko o ka zinc hehee ma 440-460 ℃. ʻO kāna mau mea maikaʻi he uhi mānoanoa (50-100μm), ka hoʻopili ikaika loa, a me ke kūpaʻa maikaʻi loa. ʻOiai inā loaʻa nā ʻōpala ma ka ʻili, hiki ke hoʻomau i ka pale ʻana i ka corrosion ma o ka hopena anode kaumaha o ka zinc, me ka lōʻihi o ka NSS o 300-1000 mau hola ma hope o ka passivation. Hōʻike kēia kaʻina hana i ke kumukūʻai maʻamau, loaʻa ka mākeke maikaʻi, a me ka haʻahaʻa hydrogen embrittlement pilikia no nā mea hoʻopaʻa ikaika kiʻekiʻe, e hoʻohana nui ʻia i nā mea hana waho.

ʻAʻole kūpono i nā hiʻohiʻona hui pololei; ʻO nā mea paʻa liʻiliʻi liʻiliʻi ma lalo o M8 pono ke kaomi lua ma hope o ka mālama ʻana, e pili ana i ka pono; a hiki i ke kaʻina hana ke hoʻololi i ka paʻakikī paʻakikī, no laila ua pāpā ʻia ka hoʻohana ʻana no nā ʻāpana 12.9-grade a i ʻole nā ​​​​mea kila kila.

4. Lapaʻau ʻeleʻele (Blueing).

Hana ʻia ka lāʻau ʻeleʻele (blueing) i kahi kiʻiʻoniʻoni hao tetroxide (Fe₃O₄) mānoanoa 1-3μm ma nā wahi paʻa ma o ka hoʻonā wela wela. ʻO kāna mau pōmaikaʻi koʻikoʻi ke kumu kūʻai haʻahaʻa, pōkole kaʻina hana, ʻaʻohe hopena i ka pololei o ka hoʻopaʻa ʻana, kūpono ia no ka pale ʻana i ka ʻōpala kumu o nā ʻāpana haʻahaʻa haʻahaʻa i loko o nā kaiapuni non-corrosive i loko. ʻAʻole pono kēia kaʻina hana i ka electroplating, ʻaʻohe pilikia o ka hydrogen embrittlement, a lawelawe ma ke ʻano he koho waiwai no nā ʻāpana i ʻike ʻole ʻia e like me nā ʻāpana hoʻoili kūloko o nā mea mīkini a me nā ʻāpana hoʻohui o nā kumu mea hana.

ʻO kāna hana anti-corrosion ka nāwaliwali loa, me ka lōʻihi o ka hoʻāʻo ʻana i ka paʻakai paʻakai kūʻokoʻa he 4-24 mau hola, hiki ke hoʻonui ʻia i 48-72 mau hola ma hope o ka hoʻopaʻa ʻana i ka aila, e hālāwai wale ana i nā pono pale kumu, a haʻahaʻa ka ʻili o ka ʻili, me ka waiwai ʻole.

II. Hoʻohālikelike Horizontal o nā hana kumu o nā kaʻina hana nui

No nā ʻōlelo aʻoaʻo maʻamau, ʻōlelo ʻia ke kūkākūkā ʻenehana loea.
