Polyethylene CAS 9002-88-4
He hydrocarbon saturated ka Polyethylene me kahi ʻano like me ka paraffin, he mea synthetic kaumaha molekala kiʻekiʻe i hana ʻia e ka polymerizing ethylene. ʻAʻohe genes polarity o nā mole polyethylene, haʻahaʻa ka omo wai, a kūpaʻa maikaʻi. ʻAʻole hoʻoheheʻe ʻia i nā mea hoʻoheheʻe maʻamau i ka mahana o ka lumi, paʻa i nā alcohols, ethers, ketones, esters, nā waikawa nāwaliwali, a me nā kumu nāwaliwali. Akā hiki iā ia ke pehu i loko o nā hydrocarbons momona, nā hydrocarbons ʻala, a me nā hydrocarbons halogenated, e ʻānai ʻia e nā waikawa ikaika i loaʻa ka oxygen, a hana i ka oxidation i ka wā e hoʻomehana ʻia ai a hoʻomālamalama ʻia paha i ka lewa.

1. Hiki ke hana ʻia ka polyethylene i loko o nā kiʻiʻoniʻoni, nā ʻūpā uea a me nā kaula, nā paipu, nā huahana hakahaka like ʻole, nā huahana i hoʻoheheʻe ʻia i ka injection, nā olonā, a pēlā aku. Hoʻohana nui ʻia ia i nā ʻoihana e like me ka mahiʻai, ka hoʻopili ʻana, a me nā kaʻa.
2. Hiki ke hoʻohana ʻia ʻo PE e hana i nā ʻaoʻao palaki hopena kiʻekiʻe a me nā mea hoʻohui rubber,
3. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopili no nā huahana ʻoihana a me nā huahana mahiʻai, ka meaʻai, ka ʻili uhi hua kanu, ka ʻili anti-seepage o ke kahawai a me ka waihona wai, a pēlā aku.
4. Hoʻohana ʻia i ka ʻoihana meaʻai ma ke ʻano he mea kōkua nau no nā lole gummy.
5. Hoʻohana ʻia ma ke ʻano he pani no ke kila, hiki ke hoʻohana ʻia hoʻi e like me nā kiʻiʻoniʻoni kūikawā, nā ipu nui, nā ʻauwai nui, nā papa, a me nā mea sintered. Noi
Hoʻopili pinepine ʻia i loko o 25kg / pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
