ʻO ka Thermoplastics e pili ana i nā plastics e palupalu i ka wā i wela ai a paʻakikī i ka wā i maʻalili. ʻO ka hapa nui o nā plastics a mākou e hoʻohana ai i ko mākou ola i kēlā me kēia lā no kēia ʻāpana. Ke wela, palupalu a kahe, a maalili, paa. Hiki ke hoʻololi a hiki ke hana hou.
ʻAʻole like nā Thermoplastics me nā plastic thermosetting.
ʻO nā plastik Thermoplastics a me nā plastic thermosetting ʻelua ʻano nui o nā plastics.
ʻO nā hiʻohiʻona o nā thermoplastics:
Ke hoʻomāhana ʻia, palupalu a hoʻololi ʻia, a i ka wā maʻalili, paʻakikī hou i ko lākou ʻano kumu. Hiki ke hana hou i keia hana i na manawa he nui.
He laina laina a lālā lālā paha ka molekala, a he nāwaliwali wale nō ka ikaika van der Waals ma waena o nā molekala, ʻaʻohe hoʻohui keʻa kemika.
ʻO nā thermoplastics o ka mea i koho ʻia he polyethylene, polypropylene, polystyrene, polyvinyl chloride, etc.
ʻO nā hiʻohiʻona o nā plastic thermosetting:
Ke hoʻomehana ʻia, hiki mai ka hopena kemika hiki ʻole ke hoʻololi ʻia, e hoʻokumu ana i kāna mau molekala i kahi ʻano ʻoihana pili kea ʻekolu-dimensional, ʻaʻole e palupalu hou a hoʻololi.
Aia nā paʻa covalent ma waena o nā molekala e hoʻokumu i kahi ʻano pūnaewele paʻa ʻekolu-dimensional.
ʻO nā plastic thermosetting representative ka resin phenolic, resin epoxy, resin polyester, etc.
Ma ka laulā, ʻo nā thermoplasticspalaki a hiki ke hana hou ia, ʻoiai ʻo ka thermosetting plastics he ikaika kiʻekiʻe a me ke kūpaʻa wela, a he mau mea koʻikoʻi nā mea ʻelua i ka ʻoihana plastics.
No laila pehea mākou e hana ai i ka ʻōpala wela i hana ʻia e nā thermoplastics i ke kaʻina hana? No ka laʻana, ʻo ka ʻōpala wela mai ka ʻoihana hoʻoheheʻe ʻia o nā plug cord power a me ka ʻoihana extrusion o nā uea a me nā kaula. ʻO nā manchines hoʻoheheʻe ʻia i ke kaula uila a me nā mea hoʻoheheʻe Cable e hoʻopuka i ka ʻōpala wela i kēlā me kēia lā. Waiho iaʻO ZAOGE ka hoʻoponopono hana hou ʻana.ʻO ZAOGE ka wili koke a me ka hoʻohana koke ʻana i ka ʻōpala wela, nā mea iʻokiʻia heʻaʻahu, maʻemaʻe, lepoʻole, pollution-free, kiʻekiʻe kiʻekiʻe, hui pū me nā mea maka e hana i nā huahana o ke kūlana kiʻekiʻe.
