Huikau e pili ana i ka hale kila anti-corrosion? Nā koho maʻamau a me nā alakaʻi koho

ʻOihana kilaHe mea koʻikoʻi ka anti-corrosion e hoʻonui i ke ola lawelawe o nā hale. ʻOkoʻa nā ʻōnaehana pale corrosion e like me nā kaiapuni kūlohelohe a me nā lawelawe lawelawe. E mālama ʻia ka loiloi piha no ka hoʻomākaukau ʻana i ka ʻili a me nā ana anti-corrosion e ʻoki i nā kumukūʻai hana mua a hoʻolōʻihi i ke ola o ka hale.

ʻO nā ʻano hale a pau e pili ana i ka hopena o nā kaiapuni corrosive, i hoʻokaʻawale ʻia i nā ʻano corrosion like ʻole e pili ana i nā kūlana lawelawe.

E koho ʻia nā ʻano hana anti-corrosion ʻokoʻa no ka hoʻokō ʻana i nā kaiapuni corrosive like ʻole. ʻAʻohe mea i hāpai ʻia, ʻo ka hoʻomākaukau ʻana i ka ʻili ke kau i ke kumu o ka pale ʻana i ka corrosion a hoʻoholo inā hiki ke hana ka pale pale e like me ka mea i hoʻolālā ʻia. Ma keʻano laulā, hoʻohana ʻia ka sandblasting a i ʻole ka pana pana no ka wehe ʻana i ka ʻōpala o nā hale hana kila, me ka pae maʻemaʻe haʻahaʻa o Sa2.5, i wehewehe ʻia he hoʻomaʻemaʻe pahū loa. Eia kekahi, e noʻonoʻo ʻia ka pae ʻōpala mua o nā substrate kila. ʻO nā mea maka i hiki ʻole ke kū i ke kūlana i koi ʻia ma hope o ka hoʻomaʻamaʻa ʻana i luna e hoʻololi ʻia a hoʻolei ʻia paha.

Ma hope o ka hoʻomākaukau ʻana i ka ʻili, ʻo ka hana aʻe ke koho i ka ʻōnaehana anti-corrosion. ʻO ka pīpī ʻana i ka pena kiʻi a me ka hoʻoheheʻe wela ʻo ia nā hopena koʻikoʻi ʻelua. Ma waho aʻe o kēia, ua hoʻohana nui ʻia nā ʻano hana anti-corrosion makua i nā papahana hana: 

(1) Hoʻoponopono ke kila hoʻoheheʻe ʻana i nā pilikia corrosion, pili i ka hapa wahohale kila, akā naʻe me nā hemahema o ke kumukūʻai kiʻekiʻe a me ka maikaʻi ʻole. 

(2) ʻO ka hoʻoheheʻe ʻana i ka wela (ka hoʻoheheʻe alumini / ka hoʻoheheʻe zinc) e hāʻawi i ka hana like me ka hot-dip galvanizing a me nā hiʻohiʻona ʻoi aku ka maikaʻi o ka hoʻololi ʻana i nā ʻāpana ʻāpana, kūpono no nā lālā kila kūikawā a me nā kaiapuni koʻikoʻi.

(3) Ke hilinaʻi nei ka palekana Cathodic i nā loina anti-corrosion electrochemical, i hoʻohana nui ʻia i nā hale kila i hoʻoheheʻe ʻia i lalo o ka wai a i kanu ʻia ma lalo o ka lepo. Hoʻohana ʻia nā ʻōnaehana pale composite hou i nā koho ʻē aʻe ma mua o nā hoʻonā maʻamau, e like me nā pale anti-corrosion i hoʻohui ʻia a me nā pale ahi a me nā graphene heavy-duty anti-corrosion coatings.

Pūnaehana hoʻoheheʻe hoʻoheheʻe nui

ʻO ka ʻōnaehana anti-corrosion spray coating no nā hale kila e kūkulu i nā pale pale multi-layer ma nā ʻāpana ʻāpana me nā hana like ʻole, ka mea i māhele nui ʻia i ʻekolu papa: primer, intermediate coat and topcoat. Hoʻohana ka primer no ka adhesion a me ka pale ʻana i ka ʻōpala. Hoʻohana mau ʻia ka epoxy zinc-rich primer me ka zinc content ʻaʻole i emi iho ma mua o 70%. He mea ʻokoʻa ka primer inorganic zinc-rich, akā ʻo kona mānoanoa kiʻiʻoniʻoni maloʻo e pono ai ka mana ikaika. Epoxy micaceous iron oxide intermediate coat no ka papa waena, a aliphatic polyurethane topcoat a i ʻole fluorocarbon topcoat i lawe ʻia e like me ke kapa hoʻopau. E hoʻopau ʻia nā kaʻina hana a pau o ka ʻōnaehana hoʻoheheʻe i loko o ka hale hana hoʻokahi e hōʻoia i ka hana paʻa a me ka hana anti-corrosion hilinaʻi.

ʻO ka hoʻoulu ʻana

Hoʻokaʻawale ʻia ʻo Galvanizing i ka galvanizing hot-dip a me ka electro-galvanizing (ka galvanizing maʻamau). Hoʻokumu ʻia ka galvanizing hot-dip (inoa piha: hot-dip galvanization) i ka uhi zinc pale ma ka hoʻokomo ʻana i ke kila i loko o ka ʻauʻau zinc hoʻoheheʻe ʻia. Hōʻike ia i ka papa zinc mānoanoa mai ka 65μm a 200μm. Me ke kūpaʻa corrosion koʻikoʻi, ke ola lawelawe lōʻihi, ka paʻa paʻa a me ke kaʻina hana maʻalahi, loaʻa iā ia ka hemahema o ka mediocre hiʻohiʻona a kūpono i nā ʻāpana hana nui. Hoʻokomo ka electro-galvanizing i ka zinc coating e pili ana i ke kumu electrolysis. He lahilahi kona papa zinc, maʻamau 20μm a 30μm. Hāʻawi ia i ka hopena hoʻonaninani maikaʻi akā paʻakikī ke kaʻina hana, pili i nā ʻāpana liʻiliʻi liʻiliʻi a i ʻole nā ​​​​hanana e koi ana i ka pale anti-corrosion māmā.

Pale ʻino nohale hana kilahoʻomaka me ka hōʻoia ʻana i ka ʻāpana corrosion o ke kaiapuni hana, hoʻopau i ka hoʻomākaukau ʻana i ka ʻili kūpono a koho i ka hopena anti-corrosion kūpono. Ma ke ʻano he mea hana kila kila ʻoihana, loaʻa iā EHSS ka ʻike hohonu o nā kaʻina hana anti-corrosion a hiki ke kōkua iā ʻoe i ke koho ʻana i nā ʻōnaehana pale corrosion e mālama i ke kumu kūʻai.
