ʻO ka ʻokoʻa ma waena o ka uhi alumini zinc a me ka plating zinc

Kau ʻia ma 2018-08-091. ʻO kēlā me kēia papa o ka zinc a me ka alumini i loko o ka zinc aluminum coating aia i loko o kahi kūlana passive, aʻo ka papa galvanized wale nō ka papa passivation o 0.05 ~ 0.2μm ma ka papa waho loa;

2. ʻO ka zinc a me nā pepa alumini i loko o ka zinc aluminum coating e pāʻani i ke kuleana piha o ka pale anode kaumaha, aʻo ka zinc coating e ʻike ʻia ka ʻōpala o ka zinc ma hope o ka luku ʻia ʻana o ka papa passivation.

3. Hiki i ka meaʻawaʻawa inorganic i loko o ka uhi a me ka uhi ke pale i ka matrix hao i ka manawa hoʻokahi i ka paleʻana i ka zinc a me ka alumini,ʻoiaiʻaʻole ka zinc plating.

4. ʻO ka zinc coating passivation layer ma 70 ~ 100 ℃ degere centigrade, ua hoʻomaka ka crystallization o ka wai e evaporate, ka hopena i ka haʻihaʻi ʻana o ka papa passivation, e hoʻopilikia i ka pale ʻana o ka zinc coating, a me ka zinc aluminum coating ma 260 degere a ʻoi aku ka mahana o ka sintering, no laila ma ia ano.
