ʻO Zn Hotplating

Nā Alahaka a me nā Hana kila:

Hoʻohana ʻia no ka hoʻohui ʻana i nā ʻāpana e like me ke alahaka nui nā kaola, trusses, guardrails, etc., e pale aku i ka corrosion mai ka ua a me nā mea hoʻoheheʻe hau (nā paʻakai chloride).

No ka laʻana, pono e kū i nā bolts o ke alahaka kai keʻa kiʻekiʻe a me ka hoʻoheheʻe ʻana o ka paʻakai, a hiki i ka papa galvanized wela ke hāʻawi i ka pale no nā makahiki he 20.

Nā alanui a me nā kaʻaahi:

ʻO nā pale kiaʻi paʻa, nā paneli hoʻopaʻa leo, a me nā mea hoʻopaʻa track no ka hoʻoponopono ʻana i ka ua waikawa, ka pau ʻana o ke kaʻa (sulfur dioxide), a me ka haumia ʻoihana.

Nā hale kiaʻi hoʻouna a me nā hale kiaʻi kamaʻilio:

Hoʻohana ʻia no ka hoʻopili ʻana i nā kumu hale kiaʻi hao a me nā crossarms, hiki iā ia ke pale i ka radiation ultraviolet, nā hekili, a me nā wahi noe waika ma nā wahi kiʻekiʻe.

2. ʻEnekinia moana a me awa
ʻO nā mea hana dock:

ʻO nā pale paʻa, nā kolamu hoʻopaʻa ʻana, nā puʻu kila, a me ka hoʻopaʻa ʻia ʻana i loko o ka wai kai no ka wā lōʻihi e pale aku ai i ka ʻino chloride ion.

Pono ka mālama mau ʻana (e like me ke pena hou ʻana me ka pena anti rust) e hoʻolōʻihi i ke ola.

Nā moku a me nā paepae o waho:

ʻO ka hoʻopaʻa ʻana i nā lako deck a me nā kākoʻo pipeline pono e hele i ka ISO 9227 salt spray test (ʻaʻohe ʻula ʻulaʻula no nā hola 1000).

'Ōlelo Aʻo: Pono paha ka hoʻonui ʻia ʻana o ke kai hohonu i ka pale ʻelua o ka galvanizing hot-dip a me ka uhi epoxy.

3. ʻOihana a me ka ikehu
Mea hana kemika:

Hoʻopaʻa paʻa pahu pahu hopena, pipeline flange, kūpaʻa i ka ʻakika a me nā kinoea alkaline (e like me ka hydrogen sulfide), ka wela kiʻekiʻe a me ka ʻāina haʻahaʻa kiʻekiʻe.

Nā hiʻohiʻona kūpono: Nā lako waho i nā mea kanu kemika a me nā mea hoʻomaʻemaʻe.

Ka mana makani a me ka photovoltaics:

Pono nā pōkā makani turbine e kū i ka haʻalulu ʻana o ka makani, ka paʻakai paʻakai kahakai, a me nā ʻokoʻa wela (-30 ° C a 50 ° C).

Pono e kū'ē nā bolts bracket photovoltaic i ka wā kahiko o UV a pale aku i ka uhi ʻana i ka pauka (ʻoi aku ka maikaʻi o ka galvanizing hot-dip ma mua o ka electroplating galvanizing).

Nā hale mahiʻai:

ʻO ke kiʻi kila hale ʻōmaʻomaʻo a me nā mea hoʻohui irrigation no ka pale ʻana i ka corrosion i hoʻokumu ʻia e nā wahi humid lōʻihi.

4. Kaona a me ka lehulehu
Nā kukui alanui a me nā kukui hōʻailona:

Hoʻopaʻa ʻia ke kumu kia kukui a me ka cantilever e pale aku i ka hoʻoheheʻe ʻia o ka ua waika kūlanakauhale a me nā mea hoʻoheheʻe hau.

hale hoʻoheheʻe wai:

ʻO ke ʻano kila e hoʻopili ana i ka pahu ea a me ka pahu sedimentation e kū kūʻē i ke kinoea hydrogen sulfide a me ka ʻōpala wai.

5. Nā Kūlana Kūikawā a me nā Kūlana
Nā wahi alkali paʻakai kiʻekiʻe:

No ka laʻana, ma ke komohana ʻākau ka ʻāina alkali a me nā wahi kahakai o ka wao nahele Hikina Hikina, pono e uhi ʻia nā bolts galvanized wela me kahi papa mānoanoa (≥ 80 μm).

Kaiapuni haʻalulu:

Pono e hoʻohālikelike ʻia nā bolts o nā ala kaʻaahi a me nā mīkini mining me nā nati anti loosening (e like me nā nati locking nylon) e pale aku i ka wehe ʻana ma muli o ka haʻalulu.

Kaiapuni wela kiʻekiʻe:

ʻO nā hiʻohiʻona lōʻihi ma luna o 200 ° C, e like me ka puni o nā boiler, hiki ke hoʻolalelale i ka oxidation o nā papa zinc a koi aku i ka hoʻohana ʻana i nā kila kila a i ʻole nā ​​​​bolts impregnated zinc.

Manaʻo koho
Kaiapuni paʻakikī: E hoʻokahua mua i nā bolts galvanized wela a hoʻohana i nā mea hoʻopaʻa sila (e like me ka mālama ʻana i ka phosphating) a i ʻole nā ​​mea hoʻopili.

Nā hiʻohiʻona koʻikoʻi o ke kumu kūʻai: Hiki i nā papahana wā pōkole a i ʻole nā ​​wahi ʻino haʻahaʻa (e like me nā wahi maloʻo o loko) ke koho i ka galvanizing, akā pono e nānā mau.

Koi ikaika kiʻekiʻe: Pono nā kī o ka papa 10.9 a ʻoi aʻe e hoʻomaʻamaʻa dehydrogenation e pale aku i ka pilikia o ka hydrogen embrittlement a me ka haki.

hōʻuluʻulu
ʻO nā bolts galvanized wela kahi koho "pae pale" no nā kaiapuni koʻikoʻi, kūpono loa no nā hiʻohiʻona waho, kai, kemika a me nā hiʻohiʻona ʻē aʻe. Aia kona waiwai nui i ka hoʻololi ʻana i nā kumukūʻai kiʻekiʻe no ka haʻahaʻa haʻahaʻa o ka mālama ʻana ma hope o ka mālama ʻana, e kūpono ana i nā papahana me nā koi kiʻekiʻe no ka palekana a me ka lōʻihi.
