Polyethylene CAS 9002-88-4
ʻO ka polyethylene kahi hydrocarbon saturated me kahi ʻano like me ka paraffin, kahi mea hana synthetic kiʻekiʻe i hana ʻia e ka polymerizing ethylene. ʻAʻohe genes polarity o nā molekele polyethylene, haʻahaʻa haʻahaʻa wai, a paʻa maikaʻi. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe maʻamau i ka lumi wela, paʻa i nā ʻawaʻawa, ethers, ketones, esters, nā ʻakika nāwaliwali, a me nā kumu nāwaliwali. Akā, hiki ke pehu i loko o ka momona hydrocarbons, aromatic hydrocarbons, a me ka halogenated hydrocarbons, e corroded e ka ikaika o ka oxygen-waikaʻakika, a undergo oxidation ke wela a i hoʻomālamalamaʻia i ka lewa.

1. Hiki ke hana 'ia ka polyethylene i mau ki'i'oni'oni, uea a me na kaula uwea, na paipu, na hua hollow like'ole, na hua i hoohehe'e ia, na fibers, a me na mea e ae.
2. Hiki ke hoʻohana ʻia ka PE no ka hana ʻana i nā kiʻi plastik kiʻekiʻe a me nā mea hoʻohui lāʻau.
3. Hiki ke hoʻohana ʻia e like me nā mea hoʻopili no nā huahana ʻoihana a me nā huahana mahiʻai, nā meaʻai, nā mea kanu kanu uhi kiʻiʻoniʻoni, channel a me reservoir anti-seepage film, etc.
4. Hoʻohana ʻia i loko o ka ʻoihana meaʻai ma ke ʻano he kōkua nau no nā candies gummy.
5. Hoʻohanaʻia ma keʻano he pani no ke kila, hiki ke hoʻohanaʻia e like me nā kiʻiʻoniʻoni kūikawā, nā pahu nui, nā kahawai nui, nā papa, a me nā mea i hoʻopaʻaʻia.
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
