Hoʻokaʻawaleductile hao huahanae pili ana i ka uhi o loko a me waho penei:
1. Ka uhi maʻamau
Hoʻopili ʻia ka pahu sima portland maʻamau i loko a pena ʻia ka zinc a me ka pena bituminous ma waho.
2. ʻO ka uhi o loko o ka pāpaʻi sima sulfate
ʻO ka sima Sulfate, ʻike ʻia hoʻi ʻo ka ciment kūpaʻa sulfate kiʻekiʻe, he kūpaʻa kūpaʻa sulfate maikaʻi a me ka hoʻohana ākea i ka lawe ʻana i kekahi mau mea ʻino loa e like me ka wai kai.
3. ʻO ka uhi o loko o ka pahu sima aluminate
ʻO ka paipu hao ductile no ka laina sewer e like me ISO7186, EN598 a me GB/T26081 ua uhi ʻia me ka sima aluminate (kahi i ʻike ʻia ʻo high-alumina cement) i loko, me ka hopena o ke kūʻē maikaʻi ʻana i ka corrosion kemika a me ke kūpaʻa abrasive i kūpono loa no ka lawe ʻana i ka wai ua, ka wai hoʻomaʻemaʻe maʻemaʻe a me kekahi ʻano wai hoʻoheheʻe ʻenehana.
4.Zinc-Aluminum uhi
Hoʻopili ʻia ka ʻili o waho o ka paipu hao me ka Zinc- Aluminum coating (85%Zn+15%Al) i kaupaona ʻia 400g/m2, i kūpono no ka lepo me ka corrosivity kiʻekiʻe.
5. ʻO ka uhi o loko o ka epoxy ceramic
ʻO ka loko o ka epoxy ceramic i hana ʻia me ka epoxy resin, quartz pauka a me nā mea ʻē aʻe me ka mānoanoa kiʻiʻoniʻoni maloʻo ʻoi aku ma mua o 1000μm, a ʻo ka maikaʻi o ka corrosion resistance electrical insulating waiwai e lilo ia i kūlana koho i ka lawe ʻana i ka wai kaona, ka wai i hoʻihoʻi ʻia, etc.
6. Epoxy resin seal coating
ʻO ka paipu hoʻoheheʻe me ka epoxy resin sealing coating e like me ka sima i loko-lining i uhi ʻia e kahi papa o ka epoxy resin sealing, nona ka mānoanoa i hoʻoholo ʻia e like me nā hiʻohiʻona o ka medium transmission, a he kūpaʻa abrasive maikaʻi a me ke kūpaʻa corrosion.Mahalo i ka uhi ʻana o ka sila, ʻoi aku ka maikaʻi o ka pale ʻana i ka ua o nā mea pōʻino, me ka pale ʻana i ka pollution i ka medium transmission a ʻoi aku ka kūpono no ka lawe pololei ʻana i ka wai inu.
7. Ka uhi polyurethane
Hana ʻia ka uhi polyurethane me nā mea polyurethane bi-component i kahi unahi, ʻaʻole wale ia e lawelawe ʻia ma ke ʻano he mea hoʻopaʻa i loko o ka paipu hao nodular, akā e like me ka uhi ʻana i waho e pili ana.ʻO ka uhi ʻana o ka polyurethane he nui nā pōmaikaʻi e like me ke kūpaʻa abrasive maikaʻi loa, ke kūpaʻa corrosion maikaʻi loa, ka non-permeation, ka ʻili maʻemaʻe, ka coefficient kūʻē liʻiliʻi, ka liʻiliʻi o ka mea hoʻohuihui kūlohelohe, ka waiwai hoʻomalu kūlohelohe, a me nā mea ʻē aʻe. ka lawe ʻana i nā mea ʻino a i ʻole nā mea ʻala me ke kūlana maʻemaʻe kiʻekiʻe, me ka wai palupalu, ka wai kai desalination, ka wai ʻino o ke kūlanakauhale, ka wai ʻino ʻoihana, a me nā mea ʻē aʻe;a ʻo kekahi me ka mānoanoa ma luna o 700μm ua hoʻohana nui ʻia i ka ʻāina lepo me ka corrosivity ikaika e like me ka lepo i haumia ʻia e ka wai ʻona ʻoihana a i ʻole me ka haʻahaʻa haʻahaʻa haʻahaʻa.
