Ka Hana ʻAna i ka ʻAʻa ʻAʻole e ʻAi i ka Pala o nā Hale Kūkulu Kila

Nā hale kilahoʻohana nui ʻia i nā hale hou, nā alahaka, a me nā hale hana ʻoihana ma muli o ko lākou ikaika kiʻekiʻe, ke kaumaha haʻahaʻa, a me nā pōʻaiapuni kūkulu pōkole. Ke hoʻohālikelike ʻia me nā hale sima kuʻuna, ʻae nā hale kila i nā ʻāpana nui, nā ʻano hoʻolālā ʻoi aku ka maʻalahi, a me ka hāʻawi wikiwiki ʻana i ka papahana. ʻO kēia mau pono e hoʻolilo i ke kila i mea kūpono no nā hale lehulehu nui, nā hale logistics, a me nā hale hana ʻoihana. Eia nō naʻe, he koʻikoʻi loa ke kila i ka corrosion electrochemical ke hōʻike ʻia i nā wahi kūlohelohe. Hiki i ka makū, ka oxygen, ka paʻakai, a me nā mea haumia ʻoihana ke hoʻoulu koke i nā hopena corrosion. ʻAʻole wale ka corrosion e pili i ke ʻano o kahi hale akā hoʻemi pū kekahi i ka ʻāpana kea o nā lālā kila. I ka hala ʻana o ka manawa, hoʻoweliweli pololei kēia kaʻina hana i ka palekana o ke kūkulu a me ka lōʻihi o ka lōʻihi. No kēia kumu, ʻo ka wehe ʻana i ka popo ʻepekema a me ka mālama anti-corrosion he mau ʻanuʻu koʻikoʻi i ka ʻenekinia hale kila.

Hoʻomākaukau ʻIli: Ke Kumu o ka Palekana Anti-Corrosion

ʻO ka wehe ʻana i ka popo o ka ʻili ka hana mua a koʻikoʻi loa i kekahi ʻōnaehana pale i ka popo. Hoʻoholo pololei kona ʻano i ka pipili a me ke ola lawelawe o nā uhi ma hope. Inā noho ka popo, ka unahi wili, a i ʻole ka ʻaila ma luna o ka ʻili kila, ʻoiai ʻo ka ʻōnaehana uhi maikaʻi loa e hāʻule mua.

I ka hana ʻoihana, ʻo ka pahū ʻana o ka ʻōpala abrasive a i ʻole ka pahū ʻana i ka pana ka hana hoʻohemo popo i hoʻohana pinepine ʻia. Hoʻopilikia nā ʻāpana abrasive wikiwiki i ka ʻili kila a wehe i ka unahi oxide, ka popo, a me nā mea haumia. Pono ka hapa nui o nā papahana i kahi pae maʻemaʻe o ka ʻili o Sa 2.5. Ma kēia pae, hōʻike ka ʻili kila i kahi waihoʻoluʻu metala like me ka ʻole o ka popo a unahi paha i ʻike ʻia, a he ʻano ʻino kona. Hoʻomaikaʻi nui kēia ʻano ʻōpala i ka ikaika hoʻopaʻa mechanical ma waena o ke kila a me ka uhi.

Hoʻohana nui ʻia ka hoʻomaʻemaʻe lima a me nā mea hana mana ma nā kahua kūkulu a i ʻole ma nā wahi i hiki ʻole ai ke hoʻohana ʻia ka pahū ʻana me ka mīkini. Hilinaʻi nā limahana i nā pulumu uea, nā wili kihi, a i ʻole nā ​​​​​​disc one e wehe i ka ʻōpala. ʻOi aku ka haʻahaʻa o ka pono o kēia ʻano hana a palena ka hopena. Loaʻa pinepine iā ia nā pae maʻemaʻe St 2 a i ʻole St 3. ʻOiai ʻaʻole hiki i kēia ʻano ke hoʻohālikelike i ka maikaʻi o ka pahū ʻana, he kuleana koʻikoʻi nō ia i ka hana mālama a me nā hoʻoponopono kūloko.

Nā ʻōnaehana uhi: Ke ʻano palekana koʻikoʻi

I ka wā o ka hana ʻana a me ka mālama ʻana i nā ʻāpana kūkulu kila, hoʻohana pinepine ʻia nā ʻōnaehana uhi multi-layer. Hoʻolōʻihi kēia mau ʻōnaehana i ke ola lawelawe ma o ka hui pū ʻana o ka pale kino a me nā ʻano pale kemika.

ʻO kahi ʻōnaehana uhi maʻamau he primer, kahi ʻaʻahu waena, a me kahi topcoat. Hāʻawi ka primer i ka laina pale mua e kūʻē i ka pala a hōʻoia i ka hoʻopili ikaika ʻana i ke kila kila. Hoʻohana nui ʻia nā primers waiwai zinc epoxy i kēia pae. Hana ka pauka zinc i loko o ka uhi ma ke ʻano he anode mōhai. Ma o ka hana electrochemical, ʻoi aku ka maikaʻi o ka zinc corrodes a pale i ke kila ma lalo mai ka popo.

Hoʻonui nui ka ʻaʻahu waena i ka mānoanoa o ka uhi a hoʻomaikaʻi i ka hana pale. ʻO ka pena ʻokikene hao epoxy micaceous kahi koho maʻamau. ʻO kona ʻano pigment e like me ka pā e pale pono i ke komo ʻana o ka mahu wai a me ka oxygen. Hoʻomaikaʻi kēia i ka mānoanoa o ka uhi a hoʻolohi i nā kaʻina hana pala.

Hoʻoikaika ka topcoat i ke kūpaʻa ʻana i ka wā a me ke ʻano. Hoʻohana pinepine nā ʻāpana kila i hōʻike ʻia i nā topcoat polyurethane a i ʻole fluorocarbon. Hāʻawi kēia mau mea i ke kūpaʻa maikaʻi loa i ka radiation ultraviolet. Pale lākou i ka chalking a me ka mae ʻana me ka hāʻawi ʻana i ke kala hoʻolālā hope loa. Mālama ka topcoat kiʻekiʻe i ka pale a me ka nani i nā makahiki he nui.

Hoʻopili pinepine nā mea hana akamai i nā uhi me ke akahele loa. No ka laʻana, hoʻopili ka Harbin Dongan Building Sheets Company i nā ʻāpana pīpī he nui i ka wā o ka hana ʻana i nā ʻāpana kila e hōʻoia i ka mānoanoa o ka ʻili maloʻo ma kahi o 75 microns. Hoʻomaikaʻi nui kēia hana i ke kūpaʻa ʻana i ka pala a hoʻolōʻihi i ke ola lawelawe.

Nā Hana Kūikawā no ka Pale ʻAna i ka Palaho

No nā hale i loko o nā wahi ʻino loa a i ʻole nā ​​​​wahi paʻakikī e mālama, pono pinepine ʻia nā ʻano palekana holomua.

ʻO ke galvanizing wela-dip ka hoʻokomo ʻana i nā ʻāpana kila i hoʻomaʻemaʻe ʻia i loko o ka zinc heheʻe ma kahi o 450°C. Hoʻokumu kēia kaʻina hana i kahi papa zinc-hao mānoanoa a mānoanoa ma luna o ka ʻili. Hāʻawi ke galvanizing wela-dip i ka palekana maikaʻi loa ma nā wahi kahakai, nā wahi pīpī paʻakai, a me nā kūlana pulu mau.

ʻO ke kila e pale aku i ka ʻino he hopena kūpono ʻē aʻe. Ma ka hoʻohui ʻana i nā mea hoʻohuihui e like me ke keleawe, chromium, a me ka nickel, hana ke kila i kahi papa popo mānoanoa a paʻa hoʻi ma luna o kona ʻili. Pale kēia papa i ka pala hou aʻe a loaʻa kahi hopena "pale-i-ka-poho" me ka ʻole o nā uhi hou aku.

I ka hopena, he mea nui ka wehe pono ʻana i ka popo a me ka pale ʻana i ka pala no ka palekana, ke kūpaʻa, a me ke ʻano o nā hale kila. ʻO ka hoʻomākaukau pono ʻana i ka ʻili, nā ʻōnaehana uhi i hoʻolālā maikaʻi ʻia, a me nā hana kūikawā kūpono e hōʻoiaʻiʻo ana e hana pono nā hale kila i ko lākou ola lawelawe i manaʻo ʻia.
