ʻO ka uhi anti-corrosion Polyurea no nā pipelines a me nā pahu wai ʻino
Wehewehe Huahana
ʻO nā uhi Polyurea he ʻāpana isocyanate a me nā polyether amines. ʻO nā mea maka o kēia manawa no ka polyurea he MDI, polyether polyols, polyether polyamines, amine chain extenders, nā mea hoʻohui hana like ʻole, nā pigments a me nā mea hoʻopiha, a me nā mea hoʻoheheʻe ikaika. Loaʻa i nā uhi Polyurea nā ʻano o ka wikiwiki o ka hoʻōla wikiwiki, ka wikiwiki o ke kūkulu ʻana, ka hana anti-corrosion maikaʻi loa a me ka hana wai ʻole, ka laulā o ka mahana, a me ke kaʻina hana maʻalahi. He kūpono loa lākou no nā ʻoihana ʻoihana a me nā ʻoihana mining like ʻole, nā wahi kaʻa, nā kahua haʻuki, a me nā mea ʻē aʻe, no ka uhi ʻana i ka papahele me nā koi no ka anti-slip, anti-corrosion a me ke kūpaʻa ʻana i ka ʻaʻahu.
NĀ HIʻOHANA HUAHANA
- ʻOi aku ka pale ʻana i ke kapa komo, kū i ke kahakaha ʻia, ʻoi aku ka lōʻihi o ke ola lawelawe;
- ʻOi aku ka paʻakikī o kona paʻa ma mua o ka papahele epoxy, me ka ʻole o ka ʻili ʻana a i ʻole ka nahā ʻana.
- He kiʻekiʻe ke koina friction o ka ʻili, e ʻoi aku ka pale ʻana i ka paheʻe ma mua o ka papahele epoxy.
- Hoʻokumu ʻia ʻana o ka ʻili ʻaʻahu hoʻokahi, maloʻo wikiwiki, kūkulu maʻalahi a wikiwiki hoʻi:
- He maikaʻi loa ka hoʻopili ʻana o ka re-coating a he maʻalahi hoʻi e hoʻoponopono.
- Hiki ke koho manawaleʻa ʻia nā kala. He nani a ʻālohilohi hoʻi. ʻAʻohe mea ʻawahia a aloha i ke kaiapuni.
ʻO ke kahua o ka anti-corrosion kahi i komo mua ai ka ʻenehana polyurea a ua hoʻohana nui ʻia i ka ʻenekinia. ʻO kāna mau noi e pili ana i ka anti-corrosion o nā hale kila e like me nā pipelines, nā pahu mālama, nā uapo, nā paila kila, a me nā pahu mālama kemika. He mānoanoa ka uhi mea, he humuhumu ʻole, he ikaika ka anti-permeation a me ka hana corrosion, hiki ke kū i ka hapa nui o ka erosion media kemika, a hiki ke hoʻohana ʻia no ka manawa lōʻihi ma nā wahi waho me ka corrosion ikaika e like me nā swamps, nā loko, ka ʻaila paʻakai, a me nā wahi pōhaku me ka ʻole o ka pauka, ka haki ʻana, a i ʻole ka ʻili ʻana. Loaʻa iā ia ke kūpaʻa maikaʻi i ka wā. ʻAʻole e haki ka uhi anti-corrosion polyurea Delsil ʻoiai inā he deformation i loko o ke kūkulu kila, a hiki nō ke uhi i ka ʻili o ka workpiece holoʻokoʻa ma nā kūlana maʻamau ʻole e like me nā protrusions a i ʻole nā depressions o nā pipelines.
Nā kaʻina hana kūkulu
ʻEnehana Anti-corrosion Hou no nā loko wai ʻino
I ka lilo ʻana o ke kūlana palekana o ke kaiapuni i mea koʻikoʻi loa, hoʻohana nā ʻano wai ʻino ʻoihana, nā wai ʻino lapaʻau, a me ka mālama ʻana i nā wai ʻino ma nā wahi kuaʻāina i ke ʻano o ka hōʻiliʻili kikowaena. Ua lilo ka pale ʻana i ka palaho o nā loko sima a i ʻole nā pahu metala i loaʻa ka wai ʻino a i ʻole ka wai ʻino i mea nui loa. A i ʻole, e hoʻoulu ia i ka lua o ka wai ʻino, e hopena ai i ka haumia mau ʻole o ka lepo. Wahi a nā helu helu piha ʻole, ʻo ke ola lawelawe o nā loko wai ʻino anti-corrosion he 15 mau manawa ma mua o nā loko wai ʻino non-anti-corrosion. ʻIke loa, ʻo ka pale ʻana i ka palaho o nā loko wai ʻino ʻaʻole wale ia he ʻāpana koʻikoʻi o nā hale mālama kaiapuni akā he waiwai huna hoʻi no nā ʻoihana.
- 1. Ka wili ʻana a me ka hoʻomaʻemaʻe ʻana i ka lua: E pulumi mua a laila e hoʻomaʻemaʻe e wehe i ka lepo, nā ʻaila aila, ka paʻakai, ka popo, a me nā mea hoʻokuʻu mai ka ʻili o ke kumu. Ma hope o ka wili pono ʻana, e hoʻoneʻe i ka lepo me ka mīkini hoʻomaʻemaʻe.
- 2. Uhi mua ʻole-solvent: Pono e hoʻopili ʻia ma ka ʻili honua ma mua o ke kūkulu ʻana. Hiki iā ia ke sila i nā pores capillary o ka papahele, hōʻemi i nā hemahema o ka uhi ʻana ma hope o ka pīpī ʻana, a hoʻonui i ka pipili ma waena o ka uhi ʻana a me ka sima a me ka papahele sima. E kali a hoʻōla piha ʻia ma mua o ka neʻe ʻana i ke kaʻina hana aʻe o ke kūkulu ʻana.
- 3. Papa hoʻoponopono putty Polyurea (i koho ʻia ma muli o nā kūlana o ke komo ʻana): E hoʻohana i ka putty patching polyurea i hoʻolaʻa ʻia no ka hoʻoponopono a me ka hoʻohālikelike ʻana. Ma hope o ka hoʻōla ʻana, e hoʻohana i kahi huila wili uila no ka wili piha ʻana a laila e hoʻomaʻemaʻe me ka mīkini ʻūlū.
- 4. Ke sila ʻana o ka primer me ka ʻole o ka solvent: E kāwili i ka primer me ka ʻole o ka solvent a me ka mea hoʻōla i ka lakio i kuhikuhi ʻia, e hoʻoulu like, a ʻōwili a ʻōpala paha i ka primer i loko o ka manawa hoʻohana i kuhikuhi ʻia. E sila i ka ʻili kumu a hoʻonui i ka hoʻopili ʻana. E hoʻōla no 12-24 mau hola (ma muli o ke ʻano o ka papahele, me ke kumumanaʻo o ke sila ʻana i ka papahele).
- 5. E pīpī i ka uhi anti-corrosion polyurea; Ma hope o ka hala ʻana o ka pīpī hoʻāʻo, e pīpī mua i ka lua pili, a laila e pīpī i ka ʻili o loko o ka paipu, e pīpī ʻia nā paipu pololei a i ʻole nā kuʻekuʻe i loko o ka hale hana, a pīpī ʻia nā hui ma kahi. E pīpī ma ke ʻano mai luna a lalo, a laila lalo, a neʻe i kahi liʻiliʻi ma ke ʻano kea. ʻO ka mānoanoa o ka uhi he 1.5-2.0mm. E hoʻopau i ka pīpī ʻana i hoʻokahi hele. Hiki ke loaʻa nā ʻano kikoʻī ma "Polyurea Engineering Coating Specifications".
- 6. ʻŌwili i ka uhi ʻana a pīpī i ka ʻaʻahu luna polyurea: E kāwili i ka mea nui a me ka mea hoʻōla i ka lakio i kuhikuhi ʻia, e kāwili maikaʻi, a hoʻohana i ka ʻōwili i hoʻolaʻa ʻia no ka ʻōwili like ʻana a i ʻole ka mīkini pīpī no ka pīpī ʻana i ka uhi ʻaʻahu luna polyurea ma luna o ka ʻili uhi polyurea i hoʻōla piha ʻia. E kūʻē i nā kukuna ultraviolet, pale i ka ʻelemakule, a me ka loli o ke kala.
Kāohi ʻana i ka palaho o ka paipa
I nā makahiki i hala iho nei, ua nui ka hoʻomohala ʻana i nā mea pale i ka pala o ka pipeline. Mai ka ʻōnaehana pale pala o ke kēpau lanahu mua a hiki i ka ʻōnaehana pale pala plastik 3PE, a i kēia manawa a hiki i nā mea hui polymer, ua hoʻomaikaʻi nui ʻia ka hana. I kēia manawa, ʻo ka hapa nui o nā ʻano pale pala he mau ʻano e like me ke kiʻekiʻe o ka paʻakikī o ke kūkulu ʻana, ke ola pōkole, ka paʻakikī o ka mālama ʻana i ka wā ma hope, a me ka maikaʻi ʻole o ke kaiapuni. Ua hoʻopiha ka puka ʻana mai o ka polyurea i kēia hakahaka ma ke kahua.
- 1. Ke one ʻana no ka wehe ʻana i ka popo: ʻO ka mea mua, ke one ʻia nā paipu no ka wehe ʻana i ka popo e like me ke kūlana Sa2.5. Pono e hoʻopau ʻia ke kaʻina hana one ʻana i loko o 6 mau hola. A laila, hoʻopili ʻia ka uhi primer polyurethane.
- 2. Hoʻopili ʻia ka primer: Ma hope o ke one ʻana, hoʻopili ʻia ka primer kūikawā me ka ʻole o ka solvent. Ma hope o ka maloʻo ʻana o ka primer i kahi kūlana kahi ʻaʻohe wai maopopo e koe ma luna o ka ʻili, pīpī ʻia ka uhi polyurethane. E hōʻoia i ka hoʻopili like ʻana e hōʻoia i ka pipili ma waena o ka polyurethane a me ka substrate paipu.
- 3. Hoʻopīpī polyurethane: E hoʻohana i ka mīkini hoʻopīpī polyurethane e hoʻopīpī like i ka polyurethane a hiki i ka mānoanoa o ke kiʻiʻoniʻoni. Pono ka ʻili e laumania, me ka ʻole o ka wai kahe, nā lua liʻiliʻi, nā pehu, a i ʻole ka māwae. No nā pohō kūloko a i ʻole nā lua liʻiliʻi, hiki ke hoʻohana ʻia ka hoʻoponopono polyurethane lima no ka hoʻopili ʻana.
