High nuʻa polyethylene: palapala noi

Low nuʻa polyethylene ua hua mai la ia mai ka maloko'etolina, a me ka organometallic hōʻeleu nei iluna triethylaluminum a me ka titanium tetrachloride. No ka polyethylene i loko o ka wahi lulu hana hoʻohana kekahi mauʻanoʻenehana Lolina i oko ma ka 'ano manao, ka mīkini'ātoma' auhau, epekema no ka hoʻomaʻemaʻe polyethylene ma ka hōʻeleu i hoʻohana.

enehana

Loa pinepine ka mea, lawe mai Kime Poʻokela kapuai o: polymerization o'etolina, kona hoomaemae ana, mai ka hōʻeleu, a me ka hope loa ka maloʻoʻana kaʻina. Ma hope o hookonokono ana i ka pāʻoihana o ke triethylaluminum a me ka titanium tetrachloride ma ka cyclohexane i hou a me ka kakolina. Enaena i ke 50 C mau-pakeneka pāʻoihana i lako i ka mīkini'ātoma, ma ka lewa-ke eaʻe nenoaiu o ka hoʻohuiʻia'etolina. E nū ana i paipai 'ia ka nuipa a hapa o ka'etolina e polyethylene polymerization.

E wehe i hōʻeleu, mai ka kūpono pīlali i waeʻia decomposition huahana a me ka mea hoʻoheheʻe. Ke polyethylene centrifuge holoi, mai ka hōʻeleu hoʻohana ' metanola.

Polyethylene o haʻahaʻa puʻe hope o holoiʻia me kaʻuwīʻia mai, a me ka puna me ia e hoʻohuiʻia i ka waiwai no ka hoʻomaikaʻi i ka mea e like ai. No ka clarification o stabilizer hoʻohana,'etolina glycol a me ka paʻakai nitrophosphate, a me ka hana ia shinier, mahuahua ua noi ia.

Eia hoi, polyethylene ua hoolilo i ka maloʻoʻana a me ka granulation. Polyethylene o haʻahaʻa puʻe ua hua mai i loko o ka palapala o ka granules a me ka pauka.

Paipu i ka haahaa nuʻa polyethylene

Ka mea, i hoʻohana 'ia no ka mea hoʻonoho o ke kinoea, sewer a me ka wai e ka'ōnaehana pūnaewele.

Paipu ua hanaʻia e ka mea ana extrusion hana. Like maka mea no ka? Iecaianoaaiiie o polyethylene i loko o granules protrudes.

Hoʻokele waiwai e hoʻomōhala ana i'āina hoʻohana mau mea hoʻokiokio, i aneane pau nenoai.

HDPE paipu mai,ʻaʻole he kūlana maikaʻiʻole i ka wai quality, no ka mea, na na paia o ka lepo ua,ʻaʻole i hanaʻia, a i ohi ia mea pōhaku paʻakai.

Low puʻe polyethylene Ua loaʻa palapala noi i loko o sewer nenoai, no ka mea, ua hoʻopale keʻano pākīkē waiwai a me ke kiʻekiʻe mahana.

Kinoea paipu ua no hoi i luku, a mai haalele i hana waiwai no ka lōʻihi manawa.

Mea paʻa - oi e like ai na ohe mai ka HDPE. Ka mea, i hawewe-hoʻopale, mai popoʻole a me ka hana i lepo, e ole crack ma lalo o ka aoao o ke kiʻekiʻe a me ka haahaa mahana. Kā lākou hana i ke ola o kekahi mau makahiki.

Polyethylene High puʻe kŘpa a palupalu a me ka laholio. He waiwai kona maloko, kŘpa a sparse hoʻoponoponoʻana o Kamehameha o na nā lātoma i kuhikuhi e loli ai kona pa apŘ. LDPE paka he ākea huahelu o films. Ka mea, i ke kiʻekiʻe loa quality, a me ka'ōpala nā maikaʻi hōʻoia mea paha e e loaʻa. Ua mālama a hānai i ke kaʻina o ka maikaʻi waiwai, a hiki i mahana mai i kanaono degere. Qualitative ano o ka polyethylene mai i hoʻololi i ma lalo o ka aoao o Nine Inch. He mea hiki ke reliably kaʻawale i ka huina hoonui mai ona mau a me ka wai ka ohu.
