He mea koʻikoʻi ke koho ʻana i ka mea paipu kūpono no ka holomua o ka papahana no ka wā lōʻihi. Hopohopo ʻoe e hūnā ana nā huaʻōlelo paʻakikī e like me "PE100" i nā pilikia.ʻO PE100 wale nō ke kūlana maʻamau o kēia au no nā paipu plastik ikaika kiʻekiʻe.

He paipu kaomi ka paipu PE100 i hana ʻia mai kahi pae hana kiʻekiʻe o High-Density Polyethylene (HDPE). Hōʻike ka "100" i kona Mana Pono Loa (MRS) i hōʻoia ʻia o 10 MPa, e hōʻoiaʻiʻo ana i kona hiki ke lawelawe i ke kaomi kiʻekiʻe no nā makahiki he 50 a ʻoi, e kūpono ana no nā ʻoihana koʻikoʻi.

Ma ke ʻano he mea hana i nā ʻōnaehana paipu no kahi kokoke i ʻelua mau makahiki, ua kūkulu wau i kaʻu ʻoihana ma luna o hoʻokahi kumumanaʻo: hoʻomaka ka hilinaʻi me ka mea maka. ʻAʻole ʻo PE100 he inoa wale nō; he kūlana honua ia a mākou a me kā mākou mea kūʻai aku e hilinaʻi nei. No nā poʻe loea e like me Arief, he luna kūʻai kiʻekiʻe ma Indonesia, he hōʻoia kēia palapala hōʻoia. ʻO ia hoʻi, ʻo ka paipu āna e hoʻokomo ai no kahi ʻōnaehana wai kūlanakauhale he ikaika ʻenekinia e mau no nā hanauna. E nānā hohonu kākou i ke ʻano o kēia kūlana a no ke aha he mea nui ia no kāu mau papahana.

Ua like anei ka HDPE me ka PE100?

ʻIke ʻoe iā HDPE a me PE100 i hoʻohana ʻia i nā kikoʻī, a ʻaʻole maopopo ka ʻokoʻa. ʻO kēia huikau e paʻakikī ai ka hoʻohālikelike ʻana i nā mea.He mana HDPE kikoʻī wale nō ʻo PE100.

ʻAʻole, ʻaʻole like loa lākou. ʻO nā PE100 a pau he HDPE, akā ʻaʻole nā ​​HDPE a pau i kū i ke kūlana PE100. ʻO PE100 kahi hoʻokaʻawale kikoʻī o ka High-Density Polyethylene i hōʻoia ʻia he ʻoi aku ka ikaika a me ke kūpaʻa i ka māwae ma mua o nā papa HDPE kahiko.

E noʻonoʻo iā "HDPE" ma ke ʻano he inoa o kahi ʻohana nui a ʻokoʻa. I loko o kēia ʻohana, aia nā hanauna like ʻole, kēlā me kēia me nā hiki ʻoi aku ka maikaʻi ma mua o ka mea hope. Ua hana ʻia nā paipu kaomi mua loa mai nā papa e like me PE63. A laila ua holomua ka ʻenehana, a ua hoʻomohala mākou iā PE80. I kēia lā, ʻo PE100 ke kūlana hana hou a kiʻekiʻe. Hōʻike ka helu ma ka inoa iā ʻoe i kona ikaika lōʻihi. No laila, ʻoiai hiki ke hana ʻia kahi paipu mai kahi resin HDPE kumu maʻamau, heResin i hōʻoia ʻia e PE100ua hōʻoia ʻia e hoʻokō i kēlā pae hoʻohālikelike ikaika kiʻekiʻe. Ke hana mākou i nā paipu kaomi ma kā mākou hale hana, hoʻohana wale mākou i ka resin PE100 puʻupaʻa. He kiko kaohi koʻikoʻi kēia. Hōʻoiaʻiʻo ia i kēlā me kēia mika o ka paipu i loaʻa ka hana i wānana ʻia a hōʻoia ʻia e koi ʻia e nā papahana ʻoihana. Hoʻopau ia i kekahi kuhi e pili ana i ka ikaika a me ke ola lōʻihi o ka mea.

Ke hoʻohālikelike nei i ka HDPE Laulā me ka PE100 i hōʻoia ʻia

He aha ka papa mea PE100?

Lohe ʻoe e pili ana i nā ʻano mea like ʻole, akā ʻo "PE100" paha he helu wale nō. Hiki i kēia ke hoʻopoina iā ʻoe i kona pono nui loa.ʻO ka papa he ʻōlelo hoʻohiki pololei ia no ka ikaika lōʻihi.

ʻO ka papa mea PE100 kahi hoʻokaʻawale honua no ka resin HDPE e hōʻike ana i ka Minimum Required Strength (MRS) o 10 Megapascals (MPa). Hōʻoia kēia papa i ka hiki o ka mea ke kū i ke kaomi kūloko ma luna o ke ola lawelawe 50 mau makahiki me ka ʻole o ka hāʻule ʻana.

ʻO ka "100" ka ʻāpana koʻikoʻi loa o ka inoa. Loaʻa ia mai ka helu 10.0 MPa. ʻO kēia kikoʻī ʻenekinia e hiki ai i nā mea hoʻolālā ke helu i ka hiki ke kaomi o kahi paipu me kahi hilinaʻi kiʻekiʻe. He pōmaikaʻi kūpono loa kēia e ʻike koke ai nā luna kūʻai me ka ʻike ʻenekinia: hoʻopilikia ia i ka mānoanoa o ka paia o ka paipu. No ka mea ʻoi aku ka ikaika o PE100 ma mua o nā papa kahiko e like me PE80, hiki iā ia ke lawelawe i ke kaomi like me ka paia lahilahi. Ana mākou i kēia me ka Standard Dimension Ratio (SDR), ʻo ia ka lakio o ke anawaena o ka paipu i kona mānoanoa o ka paia. No kahi papa kaomi i hāʻawi ʻia, ʻoi aku ka kiʻekiʻe o ka SDR (pā lahilahi) o ka paipu PE100 ma mua o ka paipu PE80. ʻO ke ʻano o kēia, ʻoi aku ka liʻiliʻi o nā mea maka i hoʻohana ʻia, ʻo ia ka mea e māmā ai ka paipu, emi ke kumukūʻai, a maʻalahi hoʻi e lawelawe a hoʻokomo. Hoʻopuka pū ia i kahi lua kūloko nui aʻe, kahi e hoʻomaikaʻi ai i ka hiki ke kahe.

Pōmaikaʻi PE100: Nā paia lahilahi, Kahe maikaʻi

He aha ka nui o ka mea PE100?

Aia ka huaʻōlelo "High-Density" ma ka inoa, akā hiki ke manaʻo ʻia he mea pohihihi. Me ka maopopo ʻole o kona manaʻo, ʻaʻole hiki iā ʻoe ke mahalo i ke kumu e hana maikaʻi ai ka mea.ʻO ke ʻano paʻa ke kumu o kona ikaika.

He Polyethylene Dākea Kiʻekiʻe ʻo PE100, a ʻo kona nui o ka mea maʻamau e hāʻule ana ma ka pae o 0.95 a i 0.97 grams no kenimika cubic (g/cm³). ʻO kēia nui kiʻekiʻe ka mea e hāʻawi ai i ka mea i kona paʻakikī, ka ikaika tensile, a me ke kūpaʻa kemika maikaʻi loa.

Mai kahi kuanaʻike hana ʻana, ʻo ka nui ka mea nui. Hoʻokumu mākou i kēia nui kiʻekiʻe ma ka pae molekala. Hana ʻia ka Polyethylene me nā kaulahao lōʻihi o nā molekala. I loko o ka High-Density Polyethylene, pololei loa kēia mau kaulahao me ka liʻiliʻi o nā lālā. ʻAe kēia iā lākou e hoʻopaʻa pū me ka paʻa loa a hana i kahi ʻano crystalline. ʻO kēia ʻano paʻa ka manaʻo o "high density". ʻO ia ke kumu he ikaika a paʻakikī ka mea. I ka hoʻohālikelike ʻana, he mau kaulahao me nā lālā he nui ka Low-Density Polyethylene (LDPE). Pale kēia mau lālā i nā kaulahao mai ka hoʻopaʻa kokoke ʻana, e hopena ana i kahi mea haʻahaʻa haʻahaʻa i palupalu a maʻalahi, e like me ka ʻeke plastik. No kahi paipu e pono ai ke paʻa i ke kaomi ma lalo o ka honua no nā makahiki he ʻumi, pono ʻoe i ka ikaika e loaʻa wale mai kēlā ʻano paʻa a kiʻekiʻe. He kumu nui kēia no ke koho ʻoi aku ka maikaʻi o PE100 no nā ʻoihana.

Ka nui a me kona hopena ma nā waiwai

He aha nā hemahema o nā paipu PE?

ʻAʻohe mea kūpono no kēlā me kēia kūlana. ʻO ka hoʻowahāwahā ʻana i nā palena o ka paipu PE hiki ke alakaʻi i nā hewa hoʻolālā a hoʻonohonoho paha. ʻO ka hoʻomaopopo ʻana i kona mau nāwaliwali e hiki ai iā ʻoe ke hoʻohana pono a maikaʻi.

ʻO nā hemahema nui o ka paipu PE ʻo ia kona nāwaliwali i ka radiation UV me ka ʻole o ka pale ʻana, kahi palena mahana hana haʻahaʻa ma mua o ka metala, a me ka wikiwiki o ka hoʻonui ʻana o ka wela. Pono pū ka hoʻonohonoho pono ʻana i nā lako fusion kūikawā a me nā mea hoʻohana i aʻo ʻia.

Ma ke ʻano he mea hana, ke manaʻoʻiʻo nei au i ka ʻoiaʻiʻo e pili ana i nā palena o kahi huahana. Kūkulu ia i ka hilinaʻi a alakaʻi i nā papahana ʻoi aku ka maikaʻi. ʻO ka mea mua, hiki ke maʻalahi ka paipu PE iKa hōʻino ʻana o ka UV mai ka lāHoʻoponopono mākou i kēia ma ka hoʻohui ʻana i kahi 2-3% kalapona ʻeleʻele i ka mea maka. ʻO ia ke kumu he ʻeleʻele mau nā paipu kaomi; hana ka ʻeleʻele kalapona ma ke ʻano he mea hoʻopaʻa UV ikaika. ʻO ka lua, he haʻahaʻa kona pae mahana ma mua o nā paipu metala. ʻAʻole pono e hoʻohana ʻia no nā noi wai wela ma luna o 60°C (140°F). ʻO ke kolu, hoʻonui a ʻaelike ia me nā loli mahana ma mua o ke kila a i ʻole ka hao ductile. No nā hoʻonohonoho ma luna o ka honua, pono e hoʻokele ʻia kēia me nā loop hoʻonui a i ʻole nā ​​​​manaʻo hoʻolālā ʻē aʻe. No nā paipu i kanu ʻia, ʻaʻole kēia he pilikia. ʻO ka hope loa, ʻo ka hui ʻana me HDPE e pono ai nā loea i aʻo ʻia a me nā lako fusion. ʻOiai he mea kūpono ʻole kēia, ʻo ia nō hoʻi kona ikaika nui loa, no ka mea e hōʻoiaʻiʻo ana i kahi hui kūpono, pale leak i kēlā me kēia manawa.

ʻO ka paipu PE100 ke kūlana kiʻekiʻe loa o ka HDPE, i wehewehe ʻia e kona ikaika a me ke kūpaʻa. ʻO ka hoʻomaopopo ʻana i kona mau waiwai a me ka hoʻokele ʻana i kona mau palena liʻiliʻi e hiki ai iā ʻoe ke kūkulu i kahi ʻoihana hilinaʻi a lōʻihi.
