He aha ke kumu o ka dezincification ma ka -wea wela?

ʻO ka wehe ʻana i ka uea wela -puʻu wale ʻia ma muli o nā hemahema ma ke kikowaena ma waena o ka papa zinc a me ka substrate. Aia kekahi mau kumu:
1. ʻO ka maikaʻi maikaʻi ʻole o ka uea galvanized, e like me ka ʻaila nui, ka ʻōpala, a me nā hemahema ʻē aʻe, hiki ke hoʻopili i ka pili ʻana o ka papa zinc i ka substrate.
2. ʻO nā hemahema e like me nā ʻōhū, ka ʻūhā, nā lua, a me nā māwae wela i ka wā o ke kaʻina hana galvanizing hiki ke hoʻopili i ka pili ʻana o ka papa zinc i ka substrate.
3. ʻO ka wela hoʻomaʻamaʻa wela kūpono ʻole o ka uea galvanized: Hiki i ka haʻahaʻa haʻahaʻa ke hoʻopili i ka ikaika hoʻopaʻa ʻana o ka papa zinc, ʻoiai ke kiʻekiʻe loa e hiki ke hoʻoulu i ka passivation a pili i ka adhesion.
4. ʻAʻohe mānoanoa o ka zinc layer: ʻOi aku paha kekahi mau wahi i ka maʻamau i ʻōlelo ʻia, ʻaʻole paha kekahi.
5. Hiki i nā kumu kaiapuni ke ho'opau i ka papa zinc, 'o ia ho'i ma ke ki'eki'e -mahana, ha'aha'a, a me nā pō'ino, hiki ke hō'emi hou i ka pili o ka papa zinc.
Inā loaʻa pinepine kēia, ʻōlelo ʻia e ʻike i ka pilikia a hoʻomaikaʻi i nā kaʻina hana a me nā mea pono.
