ʻO ka hopena anticorrosive o ke kūkulu ʻana i nā huahana uhi kala ʻo ia ka hui pū ʻana o ka uhi, kiʻi pretreatment a me ka uhi ʻana (primer, pena kiʻekiʻe a me ka pena hope), e pili pono ana i kona ola lawelawe.Mai ke ʻano anticorrosion o ka uhi kala, ʻo ka uhi kūlohelohe kahi ʻano mea hoʻokaʻawale, kahi e hoʻokaʻawale ai i ka substrate mai ka corrosive medium e hoʻokō ai i ke kumu o ka anticorrosion.
PE:ʻO ka uhi polyester no ke kila galvanized he adhesion maikaʻi, ʻoi aku ka maʻalahi o ka uhi ʻana o ka pā kila i ka hana ʻana i ka hoʻoheheʻe ʻana, ke kumukūʻai haʻahaʻa a me nā huahana, ke kala a me ka luster koho scope nui, ma lalo o ke kaiapuni maʻamau i hōʻike pololei ʻia, kona ola corrosion a hiki i 5-8 mau makahiki, akā, ma nā wahi ʻoihana a i ʻole nā wahi haumia, e hoʻemi ʻia kona ola lawelawe.
SMP:No ka hāʻawi ʻana i ka pāʻani piha i nā hiʻohiʻona o ka uhi polyester a hoʻomaikaʻi i kona lōʻihi o waho a me ka paʻa māmā, ua hoʻololi ʻia ka uhi polyester i loko o ka uhi silika i hoʻololi ʻia e ke anuanu a i ʻole ka hopena wela.Hāʻawi ʻo SMP i ka ʻoi aku ka lōʻihi a me ka pale corrosion no 10-12 mau makahiki, akā ʻoi aku ka kiʻekiʻe o kona kumukūʻai ma mua o PE, a ʻoi aku ka maikaʻi o kona adhesion a me ka hoʻoheheʻe ʻana ma mua o PE.
HDP:ʻO ka HDP he resin me ke kaumaha molekala kiʻekiʻe, ka liʻiliʻi o ke kaula polimer, ka ikehu paʻa paʻa, ʻaʻole maʻalahi i ka photolication, no laila ʻaʻole maʻalahi i ka pauka a me ka hoʻohaʻahaʻa ʻana, hoʻohana ʻo HDP i ka pigment ceramic inorganic like me PVDF, ʻoi aku ka maikaʻi o ka waiho ʻana o ka kala, uv ke kū'ē, ka lōʻihi o waho a me ka hana anti-powder, ke kumu kūʻai.

PVDF:no ka mea, PVDF kemika paʻa a me ka paʻa kemika ma waena o ka ikaika hoʻopaʻa ikehu, no laila, i ka uhi i ka maikaʻi corrosion kū'ē a me ka waihoʻoluʻu waihoʻoluʻu, i loko o ka hana hana me ka waihoʻoluʻu i uhi kila pā kila, ka mea kiʻekiʻe loa huahana, maʻamau i kapa ʻia ʻo "color plate king".ʻO kona mole he nui a pololei ke kaulahao, no laila, ma waho aʻe o ke kūʻē kemika, ʻoi aku ka maikaʻi o kona mau ʻano mechanical, uv a me ka wela.Ma ke kaiapuni maʻamau, hiki i kona ola anticorrotion a hiki i 20-25 mau makahiki, akā he kiʻekiʻe ke kumukūʻai, ʻoi aku ka kiʻekiʻe o ke kumu kūʻai o ka pā kila i uhi ʻia, ʻoi aku ka liʻiliʻi o ka luster bet, he nui nā kapu. ke koho kala (ʻaʻole hiki ke hāʻawi ʻia ke kala ʻālohilohi).
