ʻO ka mānoanoa o ka uhi ʻana ke kūlana hōʻoia nui loa no ka pale ʻana i ka corrosion.ʻOi aku ka nui o ka mānoanoa o ka uhi, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion, i hōʻoia ʻia e nā hoʻokolohua wikiwiki a me nā hoʻāʻo ʻana i ka ihu.
E like me ka mea i hōʻike ʻia ma lalo nei:

No nā papa kila waihoʻoluʻu e pili ana i ka (aluminum) zinc plated plates, pili ka mānoanoa o ka uhi ʻana i ka hana corrosion notch o nā papa kila kala.ʻOi aku ka lahilahi o ka substrate, ʻoi aku ka mānoanoa o ka papa zinc, a ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion o ka ʻoki.ʻIke ʻia i kēia manawa ma ke ao holoʻokoʻa ʻo ka zinc ratio ≥ 100 kahi pale maikaʻi mai ka ʻino ʻana o ka notch corrosion o nā papa kila i uhi ʻia.
Palapala.No ka lawe ʻana i kahi substrate 0.5mm ma ke ʻano he laʻana, ʻo ka ʻike plating i kēlā me kēia mika square ma kekahi ʻaoʻao e hiki i ka liʻiliʻi 50g.

Pehea e koho ai i ke ʻano o ka uhi
Hōʻike ʻia ka hana nui o ka uhi i nā hopena ʻike a me nā hana pale.Hiki ke hoʻokaʻawale ʻia nā puaʻa o ka uhi ʻana i nā pua puaʻa a me nā puaʻa inorganic, me nā kala ʻulaʻula a me ka luster;He ʻulaʻula maʻamau nā puaʻa inorganic, akā ʻoi aku ko lākou mau waiwai kemika a me ka pale ʻana o UV ma mua o nā puaʻa organik.
ʻO nā kapa kila i hoʻohana pinepine ʻia no nā pā kila kala, ʻo ia ka polyester (PE), silicon modified polyester (SMP), high durability polyester (HDP), a me ka polyvinylidene fluoride (PVDF).Ua kūpono kēlā me kēia topcoat no nā kūlana like ʻole, a manaʻo mākou e hoʻohana i nā huahana HDP a i ʻole PVDF ke ʻae ʻia ka ʻoihana.

No ke koho ʻana i ka primer, pono e koho ʻia ka epoxy resin inā e hoʻokūpaʻa ʻia ka hoʻopili ʻana a me ka pale ʻana i ka corrosion;No ka nānā hou aku i ka maʻalahi a me ka pale ʻana o UV, koho i ka polyurethane primer.
No ka uhi hope, inā hoʻohana ʻia ka pā kila i uhi ʻia i ka waihoʻoluʻu ma ke ʻano he pā hoʻokahi, e koho i kahi ʻāpana ʻelua ʻāpana, ʻo ia hoʻi, hoʻokahi papa o ka primer hope a hoʻokahi papa o ka hope hope.Inā hoʻohana ʻia ka pā kila i uhi ʻia i ka waihoʻoluʻu ma ke ʻano he mea hoʻohui a i ʻole ka pā sandwich, ua kau ʻia kahi papa o ka resin epoxy ma ke kua.

Ka hopena o ka mānoanoa o ka uhi ʻana i ke ola lawelawe
Hiki i ka pale kila kala ke pāʻani i kekahi hana i ka pale ʻana i ka corrosion, me ka hoʻohana ʻana i ke kiʻi ʻoniʻoni e hoʻokaʻawale i nā mea corrosive waho.Eia nō naʻe, ma muli o ke ʻano microscopic o ke kiʻi ʻoniʻoni ponoʻī, aia nō nā pores, a ʻo kahi liʻiliʻi o ka wai i loko o ka lewa e hoʻokomo mau i ka uhi ʻana, e hoʻohūhū ai ka uhi a hāʻule paha ke kiʻi uhi.No ka pā kila, hoʻopalapala
ʻO ka papa (zinc plated a i ʻole alumini zinc plated) ʻoi aku ka hopena i ke ola o ka pā kila.
No ka mānoanoa o ka uhi like, ʻoi aku ka paʻa o ka uhi lua ma mua o ka uhi mua, me ka ʻoi aku ka maikaʻi o ka corrosion a me ka lōʻihi o ke ola lawelawe.No ka mānoanoa o ka uhi ʻana, e pili ana i nā hopena hoʻāʻo corrosion pili, paipai mākou i ka uhi mua he 20 um a ʻoi aku paha, no ka mea hiki i ka mānoanoa kiʻiʻoniʻoni ke pale i ka corrosion i loko o ka manawa kūpono.
Kāohi i ka hiki ʻana mai o ka corrosion (Pono ka PVDF i ka mānoanoa o ka uhi ʻana ma muli o ka lōʻihi o ke ola o ka lawelawe ʻana, maʻamau 25 μM a ʻoi aku paha).
