ʻO ka polyurea anti-corrosion coating no nā paipu a me nā pahu wai
Hōʻike huahana
Hoʻokumu nui ʻia nā uhi polyurea i nā ʻāpana isocyanate a me nā amine polyether. ʻO nā mea waiwai o kēia manawa no ka polyurea ka nui o MDI, polyether polyols, polyether polyamines, amine chain extenders, nā mea hoʻohui hana like ʻole, nā puaʻa a me nā mea hoʻopiha, a me nā diluents ikaika. Loaʻa i nā uhi polyurea nā hiʻohiʻona o ka wikiwiki hoʻōla wikiwiki, ka wikiwiki o ke kūkulu ʻana, ka anti-corrosion maikaʻi a me ka hana wai ʻole, ka laulā ākea ākea, a me ka hana maʻalahi. He kūpono loa ia no nā ʻoihana ʻoihana like ʻole a me nā ʻoihana mining, nā kaʻa kaʻa, nā kahua haʻuki, a me nā mea ʻē aʻe, no ka uhi ʻana o ka papahele me nā koi no ka anti-slip, anti-corrosion a me ka pale ʻana.
NA HI'O HUA
- ʻO ke kūpaʻa ʻoi aku ka maikaʻi, ka pale ʻana i ka ʻōpala, ka lōʻihi o ke ola lawelawe;
- ʻOi aku ka paʻakikī ma mua o ka papahele epoxy, me ka ʻole o ka ʻili ʻana a i ʻole ka haki ʻana:
- He kiʻekiʻe ke koena friction o ka ʻili, ʻoi aku ka paheʻe ma mua o ka papahele epoxy.
- Hoʻokumu kiʻiʻoniʻoni hoʻokahi kapa, maloʻo wikiwiki, hana maʻalahi a wikiwiki hoʻi:
- Loaʻa ka hoʻopili hou ʻana a maʻalahi ke hoʻoponopono.
- Hiki ke koho manuahi. He nani a mālamalama. ʻAʻohe mea ʻawaʻawa a pili kaiapuni.
ʻO ke kahua o ka anti-corrosion kahi i komo mua ai ka ʻenehana polyurea a ua hoʻohana nui ʻia i ka ʻenekinia. Aia i loko o kāna mau noi ka anti-corrosion o nā hale kila e like me nā paipu, nā pahu mālama, nā pahu, nā puʻu kila, a me nā pahu mālama kemika. ʻOi aku ka nui o ka uhi ʻana o ka mea, ʻaʻohe ʻano, he ikaika anti-permeation a me ka hana corrosion, hiki ke kū i ka nui o ka hoʻoheheʻe ʻana o ka media kemika, a hiki ke hoʻohana ʻia no ka manawa lōʻihi ma nā wahi waho me ka ʻinoʻino ikaika e like me nā puʻu, loko, ʻaila paʻakai, a me nā wahi pōhaku me ka ʻole o ka pauka, ka pohā, a me ka ʻili. He kūʻē maikaʻi i ka wā. ʻAʻole e haki ka Delsil polyurea anti-corrosion coating inā paha he deformation i loko o ka hale kila, a hiki nō ke uhi i ka ʻili hana holoʻokoʻa a hiki i nā kūlana kūlohelohe e like me ka protrusions a i ʻole ke kaumaha o nā pipeline.
Nā kaʻina hana kūkulu
ʻO nā ʻenehana anti-corrosion hou no nā loko wai wai
Ke piʻi nui aʻe nei ke kūlana palekana o ke kaiapuni, ʻo ka wai ʻōpala ʻoihana, ka wai lāʻau lapaʻau, a me ka hoʻomaʻamaʻa ʻana i ka wai manure kuaʻāina e hoʻohana i ke ʻano o ka hōʻiliʻili kikowaena. ʻO ka anti-corrosion o nā loko ʻiʻo a i ʻole nā pahu metala i loaʻa i ka ʻōpala a i ʻole ka wai ʻino i lilo i mea nui. A i ʻole, e hoʻoheheʻe ʻia ka lua o ka lepo, e hopena i ka haumia ʻole o ka lepo. Wahi a nā helu helu piha ʻole, ʻo ke ola lawelawe o nā loko wai hoʻoheheʻe anti-corrosion he 15 mau manawa ma mua o nā loko wai ʻole anti-corrosion. Akaka, ʻo ka anti-corrosion o nā loko wai wai ʻaʻole ia he ʻāpana koʻikoʻi o nā keʻena mālama kaiapuni akā he waiwai huna no nā ʻoihana.
- 1. Ka wili ʻana a me ka hoʻomaʻemaʻe ʻana i lalo: E kahili mua a laila e hoʻomaʻemaʻe e wehe i ka lepo, nā ʻaila ʻaila, ka paʻakai, ka ʻōpala, a me nā mea hoʻokuʻu mai ka ʻili kumu. Ma hope o ka wili ʻana, e ʻohi i ka lepo lepo.
- 2. Ka uhi ʻana o ka mea hoʻoheheʻe ʻole: Pono e hoʻopili ʻia ma ka ʻili honua ma mua o ke kūkulu ʻana. Hiki iā ia ke hoʻopaʻa i nā pores capillary o ka papahele o ka papahele, e hoʻemi i nā hemahema o ka uhi ʻana ma hope o ka pīpī ʻana, a hoʻonui i ka adhesion ma waena o ka uhi a me ka sima a me ka papahele. E kali a ho'ōla piha ʻia ma mua o ka hele ʻana i ke kaʻina hana aʻe.
- 3. ʻO ka papa hoʻoponopono poliurea putty (koho ʻia ma muli o nā kūlana ʻaʻahu): E hoʻohana i ka putty patching polyurea i hoʻolaʻa ʻia no ka hoʻoponopono ʻana a me ka pae ʻana. Ma hope o ka ho'ōla ʻana, e hoʻohana i ka huila wili uila no ka wili piha ʻana a laila hoʻomaʻemaʻe.
- 4. Hoʻopaʻa paʻa ʻole me ka solvent-free: E hoʻohui i ka mea hoʻoheheʻe ʻole a me ka lāʻau lapaʻau i ka ratio i kuhikuhi ʻia, e hoʻoulu like, a ʻōwili a ʻokiʻoki paha i ka primer i loko o ka manawa hoʻohana i ʻōlelo ʻia. E hoʻopaʻa i ka ʻili kumu a hoʻonui i ka pili. E ho'ōla no nā hola 12-24 (e pili ana i ke kūlana o ka papahele, me ke kumu o ka sila ʻana i ka papahele).
- 5. E kāpīpī i ka polyurea anti-corrosion coating; Ma hope o ka hala ʻana i ka hoʻāʻo ʻana, e pīpī mua i ka lua pili, a laila e pīpī i ka ʻili o loko o ka paipu, nā paipu pololei a i ʻole nā kuʻekuʻe i loko o ka hale hana, a hoʻopaʻa ʻia nā hono ma ka pūnaewele. E kāpīpī ma ke ʻano o luna a lalo, a laila lalo, a neʻe i kahi wahi liʻiliʻi ma ke ʻano keʻa. ʻO ka mānoanoa o ka uhi ʻana he 1.5-2.0mm. E hoʻopau i ka pāpaʻi ʻana i ka hele hoʻokahi. Hiki ke loaʻa nā ʻano kikoʻī ma "Polyurea Engineering Coating Specifications".
- 6. Ka'ōwili a me ka pulupulu polyurea kapa luna: E hoʻohui i ka mea nui a me ka lāʻau lapaʻau i loko o ka lākiō i kuhikuhi ʻia, e hoʻoulu maikaʻi, a hoʻohana i ka wili i hoʻolaʻa ʻia no ka ʻōwili like ʻole a i ʻole ka mīkini hoʻoheheʻe no ka pīpī ʻana i ka uhi uhi polyurea ma luna o ka uhi uhi polyurea i hoʻōla piha ʻia. E pale i nā kukuna ultraviolet, pale i ka ʻelemakule, a me ka loli kala.
Paipai Paipu
I nā makahiki i hala iho nei, ua nui ka hoʻomohala ʻana i nā mea pale i ka corrosion pipeline. Mai ka ʻōnaehana pale corrosion corrosion mua i ka ʻōnaehana pale corrosion plastic 3PE, a i kēia manawa i nā mea polymer composite, ua hoʻomaikaʻi nui ka hana. I kēia manawa, ʻo ka hapa nui o nā hana pale corrosion he mau hiʻohiʻona e like me ka paʻakikī o ke kūkulu ʻana, pōkole ke ola, paʻakikī ka mālama ʻana i ka wā hope, a me ka maikaʻi ʻole o ke kaiapuni. ʻO ka puka ʻana o ka polyurea ua hoʻopiha i kēia āpau i ke kula.
- 1. Sandblasting no ka hoʻopau ʻana i ka ʻōpala: ʻO ka mea mua, ua hoʻoneʻe ʻia nā paipu no ka wehe ʻana i ka ʻōpala i ka maʻamau Sa2.5. Pono e hoʻopau ʻia ke kaʻina hana sandblasting i loko o 6 mau hola. A laila, hoʻopili ʻia ka polyurethane primer coating.
- 2. Hoʻohana mua: Ma hope o ka sandblasting, hoʻohana ʻia ka mea hoʻoheheʻe-noa kūikawā. Ma hope o ka maloʻo ʻana o ka primer i kahi kūlana ʻaʻohe wai i ʻike ʻia ma luna o ka ʻili, hoʻopuʻi ʻia ka uhi polyurethane. E hōʻoia i ka noi ʻana e hōʻoia i ka pili ʻana ma waena o ka polyurethane a me ka substrate paipu.
- 3. Hoʻopuʻi polyurethane: E hoʻohana i ka mīkini hoʻoheheʻe polyurethane e pīpī i ka polyurethane me ke kaulike a hiki i ka loaʻa ʻana o ka mānoanoa kiʻiʻoniʻoni. Pono ka ʻili e maʻemaʻe, me ka ʻole o ka holo ʻana, nā pinhole, nā ʻōhū, a i ʻole ka pohā. No nā pōʻino kūloko a i ʻole pinholes, hiki ke hoʻohana ʻia ka manual polyurethane repair no ka paʻi ʻana.
