Ke nānā nei ʻoe i nā kikoʻī paipu a ʻike i nā code e like me PE80 a me PE100. He huikau kēia ʻōlelo loea, a ʻo ke koho ʻana i ke ʻano hewa hiki ke hoʻopilikia i ka pono lōʻihi o kāu papahana.

ʻO ke ʻano o PE100, ua hana ʻia ka paipu mai ka hanauna hou loa o High-Density Polyethylene (HDPE). ʻO ka "100" ke hōʻike nei i ka Minimum Required Strength (MRS) o 10.0 MPa. ʻO kēia ka mea e ʻoi aku ka ikaika a me ka paʻa e hiki ai ke hana i nā paia paipu lahilahi ma ka helu kaomi like.

Ke kamaʻilio wau me nā luna kūʻai e like me Budi, he kumuhana pinepine kēia mau māka mea. He mea maʻalahi ke ʻike iā lākou he mau helu wale nō, akā ʻo "PE100" ke hōʻike nei i nā makahiki he ʻumi o ka holomua ʻana o ka ʻepekema mea. He ʻōlelo hoʻohiki ia no ka ikaika, ka hilinaʻi, a me ka hana lōʻihi. ʻO ka hoʻomaopopo ʻana i ke ʻano o kēia code maʻalahi ke kī i ka hana ʻana i kahi hoʻoholo kūʻai akamai e hōʻoiaʻiʻo ana i ka holomua o kāu mau ʻōnaehana hoʻokele wai no nā makahiki e hiki mai ana. E wehewehe kākou i ke ʻano maoli o kēia māka no kāu mau papahana.

ʻOi aku ka maikaʻi o ka PE100 ma mua o ka PVC?

He mea maʻamau ka PVC a he haʻahaʻa pinepine ke kumukūʻai mua. ʻO kēia ka mea e hoʻowalewale ai i ke koho ʻana, akā ʻo kona paʻakikī a me ke ʻano o ka hui ʻana hiki ke alakaʻi i nā pilikia i ka wā e hiki mai ana a me nā kumukūʻai holoʻokoʻa kiʻekiʻe.

No nā paipu wai i kanu ʻia, ʻoi aku ka maikaʻi o PE100. ʻO kona maʻalahi, ʻoi aku ka kiʻekiʻe o ke kūpaʻa ʻana i ka hopena, anā hui i hoʻopili ʻia me ka pale leakahāʻawi i ka hilinaʻi lōʻihi loa. ʻO nā hui solvent-welded a gasketed paha o PVC ka mea nāwaliwali loa i ka ʻōnaehana, kahi pilikia ekuʻihao fusionhoʻopau loa.

ʻOiai he maikaʻi nā mea ʻelua no kekahi mau noi, ʻike maopopo ʻia ko lākou ʻokoʻa nui i nā kūlana paʻakikī. ʻO ka pōmaikaʻi nui loa o PE100 ʻo ia ke ʻano hui. Ke hoʻomehana ʻoe i ka fuse i kahi paipu HDPE, lilo ka hui i ʻāpana palaki hoʻokahi, paʻa, e like me ka paipu ponoʻī. ʻAʻole hiki ke liki. ʻO nā hui PVC, e hilinaʻi ana i ka sima solvent a i ʻole nā ​​​​gaskets rubber, e hoʻolauna i kahi kiko o ka hāʻule ʻana. I ka hala ʻana o ka manawa, hiki i ka neʻe ʻana o ka lepo a me nā loli kaomi ke hoʻopilikia i kēia mau hui. ʻAe pū ka maʻalahi o PE100 i ka hoʻokomo ʻana i nā ʻauwaha ʻole, hiki ke hōʻemi nui i ka manawa kūkulu a me ke kumukūʻai, kahi pōmaikaʻi nui i nā wahi kūlanakauhale piha. ʻO PVC, ʻoiai he paʻa, pono i ka ʻeli ʻana i ka ʻauwaha ākea kuʻuna, ʻoi aku ka hoʻopilikia a me ke kumukūʻai.

He aha ka ʻokoʻa ma waena o PE 80 a me PE100?

ʻIke ʻoe i ʻelua mau ʻōlelo, hoʻokahi no ka paipu PE80 a hoʻokahi no PE100. Me he mea lā kokoke nā helu, akā ʻo ke koho ʻana i ka papa haʻahaʻa e mālama i kahi kālā liʻiliʻi paha ke ʻano o ke kau ʻana i kahi paipu nāwaliwali.

ʻO ka helu e pili ana i ka Mana Pono Loa (MRS) ma hope o 50 mau makahiki. ʻO 10.0 MPa ka MRS o PE100, ʻoiai ʻo 8.0 MPa ka PE80. ʻO kēia hoʻonui 25% o ka ikaika e hiki ai i nā paipu PE100 ke loaʻa nā paia lahilahi no ka helu kaomi like.

ʻO kaKa Manawa Koi Haʻahaʻa Loa (MRS)he waiwai ia e wehewehe ana i ka ikaika lōʻihi o ka mea. Hoʻoholo nā kānaka ʻepekema ma ke kau ʻana i ka paipu ma lalo o ke kaomi a me ke ana ʻana i ka lōʻihi o ka hāʻule ʻana, a laila e hoʻohana ana i kēlā ʻikepili e wānana i kona ikaika ma luna o ke ola lawelawe 50 mau makahiki. ʻO ke kiʻekiʻe o ka MRS, ʻoi aku ka ikaika o ka mea.

ʻO kēia pōmaikaʻi ikaika 25% o PE100 ma luna o PE80 e hāʻawi iā ʻoe i ʻelua mau pono nui. ʻO ka mea mua, no kahi paipu o ka mānoanoa like, hiki iā PE100 ke lawelawe i kahi kaomi kiʻekiʻe. ʻO ka lua, a ʻoi aku ka nui no ka mālama kālā, hiki iā ʻoe ke hoʻohana i kahiPaipu PE100 me ka paia lahilahie hoʻokō i ka helu kaomi like me ka paipu PE80 mānoanoa. ʻO ka paia lahilahi ke ʻano o ka liʻiliʻi o ka mea maka i hoʻohana ʻia, ka mea e māmā ai ka paipu a ʻoi aku ka maikaʻi o ke kumukūʻai. ʻOi aku ka maʻalahi o ka lawe ʻana i ka paipu māmā a maʻalahi hoʻi e lawelawe ma kahi. Hoʻokumu pū ka paia lahilahi i kahi anawaena kūloko nui aʻe, kahi e hoʻomaikaʻi ai i ke kahe wai a hoʻemi i nā kumukūʻai pumping ma luna o ke ola o ka ʻōnaehana.

ʻO wai ka mea maikaʻi, HDPE a i ʻole PE?

Hoʻohana pinepine ʻia nā huaʻōlelo PE a me HDPE ma ke kamaʻilio like. Hiki i kēia ke huikau, e manaʻo ai ʻoe e hoʻohālikelike ana ʻoe i ʻelua mau mea like ʻole i ka wā ʻaʻole ʻoe.

He nīnau hoʻopunipuni kēia, ʻoiai ʻo HDPE (High-Density Polyethylene) he mea kikoʻīʻanoo PE (Polyethylene). ʻO PE ka inoa ʻohana ākea. No nā paipu kaomi no ka wai a me ke kinoea, ʻo HDPE ke koho kūpono a ʻoi aku ka maikaʻi ma muli o kona ikaika a me ke kūpaʻa.

E noʻonoʻo iā "Polyethylene" (PE) ma ke ʻano he inoa ʻohana no kahi hui holoʻokoʻa o nā plastics. I loko o kēia ʻohana, aia kekahi mau ʻano like ʻole e pili ana i ko lākou nui molekala, ka mea e hoʻoholo ai i ko lākou mau waiwai kino.

• PE (Polyethylene):ʻO ka mahele holoʻokoʻa.
• LDPE (Polyethylene Haʻahaʻa-Density):He palupalu loa, hoʻohana ʻia no nā mea e like me nā ʻeke palaki a me nā kiʻiʻoniʻoni. ʻAʻole kūpono ia no nā paipu kaomi.
• HDPE (Polyethylene ʻAno Kiʻekiʻe):ʻOi aku ka ikaika, ʻoi aku ka paʻa, a me ka paʻakikī. ʻO kēia ka mea maʻamau no nā paipu kaomi i hoʻohana ʻia i ka hoʻolako wai, ka hoʻolaha kinoea, a me nā noi ʻoihana.

No laila, ke kamaʻilio mākou e pili ana i ka paipu PE ma ke ʻano o ka hoʻokele wai, kokoke mau mākou e kamaʻilio e pili ana i ka paipu HDPE. ʻO nā māka a mākou i kūkākūkā ai ma mua, ʻo PE80 a me PE100, he mau hoʻokaʻawale hana kikoʻī o ka resin HDPE. No laila, ʻaʻole ka nīnau "HDPE a i ʻole PE?" akā, "ʻO wai ka māka o HDPE i kūpono no kaʻu papahana?". No kekahi hoʻonohonoho hou ʻana, ʻo ka māka PE100 HDPE ke koho maikaʻi loa.

Hiki iā ʻoe ke hoʻoheheʻe iā PE80 a i PE100?

Pono ʻoe e hoʻoponopono i kahi paipu wai kahiko i hana ʻia me PE80. ʻO kāu waihona hou he PE100 wale nō. ʻO ka wili ʻana ma waena o nā mea ʻelua e hiki ke hoʻopilikia nui i ka lawelawe.

ʻAe, hiki iā ʻoe ke hoʻoheheʻe pololei iā PE80 i PE100. No ka mea, no ka ʻohana polyethylene lāua ʻelua, e hui pū kā lāua mau plastics. Eia nō naʻe, pono ʻoe e hoʻohana i nā palena hoʻoheheʻe no ka PE80 haʻahaʻa, a ʻo ka hui e like me ka ikaika o ka hui PE80.

He nīnau koʻikoʻi loa kēia no ka mālama ʻana a me ka hana hoʻoponopono. ʻO ka hiki ke hoʻohui i nā papa like ʻole he pono nui ia o HDPE. No ka mea, ua hana ʻia ʻo PE80 a me PE100 mai ka polymer kumu hoʻokahi, ua kūlike ko lākou mau ʻano molekala a e hui pū i ka wā o ka hoʻoheheʻe wela e hana i kahi pilina paʻa a mau loa.

Eia nō naʻe, aia kekahi kānāwai koʻikoʻi e pono ʻoe e hahai:e hoʻohana mau i nā palena hoʻoheheʻe (mahana, manawa, a me ke kaomi) i kuhikuhi ʻia no ka mea haʻahaʻa.Hiki i ka PE80 a me ka PE100 ke loaʻa nā ʻano hoʻoheheʻe ʻokoʻa iki, a ʻo ka hoʻohana ʻana i nā hoʻonohonoho no PE100 hiki ke wela nui a hōʻino paha i ka hopena paipu PE80, e hopena ana i kahi hui nāwaliwali. ʻO ka lua o ka mea e hoʻomanaʻo ai, ʻo ka ʻōnaehana wale nō ka ikaika e like me kona loulou nāwaliwali loa. ʻO ka hui i hoʻopaʻa ʻia a me ka ʻāpana pipeline holoʻokoʻa e loaʻa kahi helu kaomi a me ke ʻano hana o ka paipu PE80, ʻaʻole ka PE100. ʻOiai no nā papahana hou ke paipai mau nei mākou iā PE100, kūpono kēia kūlike no ka hoʻonui ʻana a i ʻole ka hoʻoponopono ʻana i nā ʻōnaehana kahiko.

Hopena

PE100ʻaʻole ia he code wale nō; he pae ia o ka HDPE hana kiʻekiʻe. ʻO kona ikaika kiʻekiʻe a me ka hilinaʻi e lilo ia i kūlana hou no ke kūkulu ʻana i nā paipu wai paʻa a lōʻihi.
