Nā hiʻohiʻona a me nā ʻano o ka polymer thermoplastic

ʻO ka polymer thermoplastic kahi ʻano polymer i ʻike ʻia e kona hiki ke hoʻoheheʻe ʻia a laila paʻa r.epeʻaʻohe hoʻololi koʻikoʻi i kona mau waiwai kemika a i ʻole nā ​​hiʻohiʻona hana. ʻO nā polimer thermoplastic hoʻohana nui ʻia i nā ʻano noi like ʻole, me ka hoʻopili ʻana, nā ʻāpana automotive, nā ʻāpana uila, a me nā mea lapaʻau, a me nā mea ʻē aʻe.

Hoʻokaʻawale ʻia nā polymers Thermoplastic mai nā ʻano polymers ʻē aʻe, e like me nā polymers thermosetting a me nā elastomers, ma ko lākou hiki ke hoʻoheheʻe ʻia a hoʻoponopono hou i nā manawa he nui. ʻO kēia ma muli o ka hana ʻana o nā polymers thermoplastic i nā kaulahao lōʻihi o nā molekala i hoʻopaʻa ʻia e nā ikaika intermolecular nāwaliwali. Ke hoʻohana ʻia ka wela i kahi polymer thermoplastic, nāwaliwali kēia mau pūʻali intermolecular, e ʻae ana i nā kaulahao e neʻe me ka manuahi a ʻoi aku ka maʻalahi o ka mea.

ʻO kekahi o nā pono nui o nā polymers thermoplastic ko lākou versatility. Hiki iā lākou ke hoʻolālā ʻia e loaʻa i kahi ākea o nā ʻano kino a me nā mīkini, e like me ka maʻalahi, ka paʻakikī, ka ikaika, a me ke kūʻē ʻana i ka wela, nā kemika, a me ka radiation UV. ʻO kēia ke kūpono iā lākou no nā ʻano noi like ʻole e koi ana i nā ʻano hana kikoʻī.

ʻO kekahi pono o nā polymers thermoplastic ko lākou maʻalahi o ka hana. No ka mea hiki iā lākou ke hoʻoheheʻe ʻia a hoʻoponopono hou ʻia i nā manawa he nui, hiki iā lākou ke hoʻoheheʻe ʻia i loko o nā ʻano paʻakikī me ka hoʻohana ʻana i nā ʻano hana like ʻole, e like me ka injection molding, extrusion, blow molding, a me thermoforming. Hoʻolilo kēia iā lākou i koho kūpono no ka hana nui o nā ʻāpana a me nā ʻāpana.

Nui nā ʻano like ʻole o nā polymers thermoplastic, kēlā me kēia me kāna ʻano ponoʻī o nā waiwai a me nā noi. Aia kekahi o nā ʻano maʻamau:

1. Polyethylene (PE): He polymer thermoplastic i hoʻohana nui ʻia no kona kumu kūʻai haʻahaʻa, maʻalahi, a me ke kūʻē ʻana i ka hopena a me nā kemika. Hoʻohana ʻia ia i nā ʻano hana like ʻole, me ka hoʻopili ʻana, nā paipu, a me ka insulation uea.
2. ʻO Polypropylene (PP): ʻO kekahi polymer thermoplastic i hoʻohana nui ʻia no kona ʻoʻoleʻa, paʻakikī, a me ke kūpaʻa ʻana i ka wela a me nā kemika. Hoʻohana ʻia ia i nā ʻano noi like ʻole, me nā ʻāpana automotive, packaging, a me nā mea lapaʻau.
3. Polyvinyl chloride (PVC): He polymer thermoplastic i ʻike ʻia no kona maʻalahi, kūpaʻa, a me ke kūpaʻa ʻana i ke ahi a me nā kemika. Hoʻohana ʻia ia i nā ʻano hana like ʻole, e like me nā paipu, ka insulation wire, a me ka papahele.
4. Polystyrene (PS): He polymer thermoplastic i ʻike ʻia no kona ʻākaka, paʻa, a me ke kumu kūʻai haʻahaʻa. Hoʻohana ʻia ia i nā ʻano noi like ʻole, me ka hoʻopili ʻana, nā kīʻaha disposable, a me ka insulation.
5. ʻO Acrylonitrile-butadiene-styrene (ABS): He polymer thermoplastic i ʻike ʻia no kona ikaika, paʻakikī, a me ke kūʻē ʻana i ka wela a me ka hopena. Hoʻohana ʻia ia i nā ʻano hana like ʻole, me nā ʻāpana automotive, nā mea pāʻani, a me nā mea uila.

Ma waho aʻe o kēia mau polymers thermoplastic maʻamau, nui nā ʻano ʻē aʻe i loaʻa, kēlā me kēia me kona mau pono ponoʻī a me nā noi. ʻO kekahi mau hiʻohiʻona ʻē aʻe he polycarbonate (PC), polyamide (PA), polyethylene terephthalate (PET), a me nā fluoropolymers e like me polytetrafluoroethylene (PTFE).

ʻO ka holoʻokoʻa, ʻo nā polymers thermoplastic kahi koho maʻalahi a me ke kumu kūʻai no ka nui o nā noi. ʻO ko lākou hiki ke hoʻoheheʻe ʻia a hoʻoponopono hou ʻia i nā manawa he nui, i hui pū ʻia me ko lākou ākea ākea o ke kino a me nā ʻano mechanical, e lilo lākou i mea waiwai i nā ʻoihana he nui.
