Hoʻohana ʻia ʻo PE Pipe a puni ka honua i nā papahana like ʻole.Mai ka makahiki 1950, ua hāʻawi kēia ʻano paipu i nā pono nui i nā luna o ka papahana a ua helu nui ʻia i kekahi mau noi ma luna o nā ʻōnaehana e hoʻohana ana i ke kila, sima a i ʻole nā ​​​​mea ʻē aʻe.E wehewehe kēia ʻatikala i ke ʻano o ka paipa PE a pehea e hoʻohana ʻia ai.
He aha ka paipu PE?
ʻO ka paipu PE he paipu i hana ʻia me ka polyethylene (PE).Hana ʻia kēia mau paipu i nā mea thermoplastic, i hana ʻia e ka polymerization o ka ethylene.Hana ʻia ka paipu PE ma o kahi kaʻina i kapa ʻia ʻo extrusion, no laila maʻalahi ka hana ʻana i nā paipu o nā ʻano nui.
Kū maikaʻi nā paipu PE i ke kaomi, no laila ua hoʻohana ʻia lākou no nā noi kaomi like ʻole a hana ʻia i nā ʻano hoʻohālikelike.Hiki iā ʻoe ke loaʻa ka paipu PE me nā anawaena a hiki i 1200 mm.ʻO ka liʻiliʻi loa he 0.5 iniha ke anawaena.
Hiki iā ʻoe ke kūʻai i ka paipu PE ma nā lōʻihi pololei a i ʻole i nā ʻōwili ʻōwili.ʻO nā paipu me nā anawaena liʻiliʻi ke kūʻai pinepine ʻia i loko o nā wili a ʻo nā paipu pololei a hiki i 40 kapuaʻi, ʻoi aku ka nui o nā anawaena.ʻO kēia mau paipu a pau he māmā a hāʻawi i kahi kūlana kūpono o ka maʻalahi.
Ua ʻike ʻia ka paipu PE no kāna mau ʻano ʻē aʻe, e like me ka paʻakikī a me ka lōʻihi.He koho maikaʻi kēia i nā papahana kahi e koi ai ka paʻakikī.Ke pale aku nei nā paipu PE i nā kemika, no laila kōkua lākou i ka mālama ʻana i kahi lako mai ka hoʻopilikia ʻia e nā toxins.
ʻIke pinepine ʻia nā paipu ʻeleʻele ʻeleʻele i hana ʻia me ka polyethylene i ka lawe ʻia ʻana a puni a kokoke i nā papahana wai.Hana ʻia kēia mau paipu PE ʻeleʻele e ka extrusion hoʻokahi.Aia kekahi mau paipu ʻē aʻe i hana ʻia e ka extrusion pālua, he ʻeleʻele nō hoʻi, akā he kala kala.
