ʻO ka ʻike pili i ka corrosion o ka paipu PE

Paipu PEhoʻohana nui ʻia i ko mākou ola a pāʻani i kekahi kuleana.I mea e hoʻohana maikaʻi ai a mālama i kēia huahana, pono e hoʻomaopopo i ka ʻike pili o ka PE pipe corrosion.
Hoʻouka kemika: ʻO ka hoʻouka kemika o ka paipu PE ma muli o ka hoʻouka pololei ʻana o ka hana kemika maʻemaʻe ma waena o ke ʻano metala a me ka non-electrolyte.ʻO ia hoʻi, ma hope o ka hoʻopili pololei ʻana o ka metala me ka mea waena, hiki ke kaʻina hana ablation o nā ion metala ma luna o ka ʻili metala, a ua lohi ka wikiwiki ablation.
Electrochemical corrosion: ʻO ka pōʻino i hana ʻia e ka ʻino electrochemical o ka ʻili metala a me ka hana electrochemical o ka ionic conductive medium o ka paipu PE ʻo ia ke kaʻina hana electrolysis metala i loko o ka pākaukau mua i haku ʻia me ka metala a me ka electrolyte.Ma nā wahi a pau, ʻo ka pane corrosion e like me ke ʻano electrochemical me ka liʻiliʻi o hoʻokahi pane anodic a me hoʻokahi pane cathodic i hoʻopili ʻia e ke kahe o nā electrons ma o ka metala a me ke kahe ʻana o nā ion i ka waena.
ʻAi ʻino: He paʻakikī ke ʻano o ka hoʻoheheʻe ʻana i ke kila, akā i kekahi mau lepo, ʻekolu ʻano bacteria i komo i ke kaʻina hana: sulfate-reducing bacteria, sulfur-oxidizing bacteria, a me ka hao bacteria.
ʻO ka paipu PE he huahana polyethylene plastic pipe, ʻo ke kumu e koho ai nā kānaka i kēia paipu ʻo kāna hana kiʻekiʻe a me ke kumu kūʻai.He maʻalahi a wikiwiki ke kau ʻana o nā paipu PE, me ka haʻahaʻa haʻahaʻa a me nā kumukūʻai mālama.ʻOiai maikaʻi ka hui ʻana, hiki iā ia ke pale i nā ukana axial me ka ʻole o ka leakage.
ʻO ka hopena, ʻaʻole pono nā wahi heleuma a me nā pier ma nā hono a me nā piko no ka waiho ʻana, e hoʻemi ana i nā kumukūʻai.Hoʻohana nui ʻia ka polyethylene (PE) ma ke kahua o ka hana ʻana i ka paipu wai ma muli o kona ikaika kiʻekiʻe, ke kūpaʻa ʻana a me ka mea ʻole.ʻAʻole ia e ʻōpala a he huahana kūpono ia e pani ai i nā paipu wai hao maʻamau.
I ka manawa like, ma muli o kona kaumaha māmā, paʻakikī maikaʻi, kūʻē i ka hopena maikaʻi, kumu kūʻai kūʻai haʻahaʻa a me ke kūpaʻa haʻahaʻa haʻahaʻa maikaʻi, hoʻohana nui ʻia nā paipu PE i ke kūkulu ʻana i ke kūlanakauhale, ka waiwai a me nā hale hana.ʻO nā paipu paipu PE he kaiaola a me ke kaiapuni, ʻaʻohe mea hoʻohui i hoʻohui ʻia i ka wā o ke kaʻina hana.ʻO ke ʻano o ka paia o loko o ka pipeline he maʻemaʻe, ʻaʻohe scaling a me ka bacteria, a ʻo ka hana ʻana, ka pilina a me nā ʻenehana kūkulu hale.Wahi a kona mau waiwai kino a me ka mechanical, hoʻohana ia i ka pilina hoʻoheheʻe wela a i ʻole ke kākoʻo flange kākoʻo, nona ka paʻakikī kiʻekiʻe, ka pilina pili pono, ke kūkulu kūpono ʻana, ka coefficient pale kiʻekiʻe a me ka helu leakage haʻahaʻa.
