He aha ka thermoplastics?
ʻO Thermoplastics kekahi papa o nā plastics i paʻa i kekahi mahana, paʻa ma hope o ka hoʻolili ʻana, a hiki ke hana hou i kēia kaʻina hana. Hōʻike ʻia ke ʻano molekala e kahi hui polymer linear, ʻaʻohe hui ikaika, a ʻaʻole i hoʻopaʻa ʻia i ka laina laina intermolecular crosslinking i ka wā wela. Hiki ke hana hou ʻia nā mea ʻōpala i nā huahana hou ma hope o ka hana hou ʻana. ʻO nā ʻano nui he polyolefins (vinyl, olefins, styrenes, acrylates, fluorine-containing olefins, etc.), cellulose, polyether polyesters and Aromatic heterocyclic polymers, etc.
Definition
ʻO Thermoplastics ka mea i hoʻohana nui ʻia. Hoʻokumu ʻia lākou me ka resin thermoplastic e like me ka mea nui a me nā mea hoʻohui like ʻole. Ma lalo o kekahi mau kūlana wela, hiki i nā plastics ke palupalu a hoʻoheheʻe paha i kekahi ʻano, a ʻaʻole hoʻololi ke ʻano ma hope o ka hoʻoilo; hiki ke hana hou i kēia moku'āina i nā manawa he nui a loa'a mau ka plasticity, a he ho'ololi kino wale nō kēia hana hou 'ana, i kapa 'ia he thermoplastic. palaki.
Me ka polyethylene, polypropylene , polyvinyl chloride, polystyrene, polyoxymethylene, polycarbonate, polyamide, acrylic plastics, nā polyolefins ʻē aʻe a me kā lākou copolymers, polysulfone, polyphenylene ether
Hoʻolālikelike ʻana
Hiki ke hoʻokaʻawale ʻia nā Thermoplastics i nā plastics kumu nui, plastics engineering, a me nā plastics kūikawā e like me kā lākou mau hiʻohiʻona hana, ākea o ka hoʻohana ʻana, a me ka versatility o ka ʻenehana molding.
ʻO nā hiʻohiʻona nui o nā plastics maʻamau: ka noi ākea, ka hana maʻalahi, a me ka hana holoʻokoʻa maikaʻi. E like me ka polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS), acrylonitrile-butadiene-styrene (ABS) i ʻike pū ʻia ʻo "ʻelima mau mea hana maʻamau".
ʻO nā hiʻohiʻona o nā plastics ʻenekinia a me nā plastics kūikawā: ʻoi aku ka maikaʻi o kekahi mau hale a me nā waiwai o nā polymers kiʻekiʻe, a i ʻole ka paʻakikī o ka ʻenehana hana hoʻoheheʻe ʻana, a me nā mea ʻē aʻe, a hoʻohana pinepine ʻia i ka ʻenehana loea a i ʻole nā kahua kūikawā a me nā hanana. ʻO nā plastics ʻenehana nui: nylon (Nylon), polycarbonate (PC), polyurethane (PU), polytetrafluoroethylene (Teflon, PTFE), polyethylene terephthalate (PET), a me nā mea'ē aʻe, nā Plastics kūikawā e like me "nā puʻuwai synthetic" a me nā "hui artificial" e like me nā "polymer lāʻau".
