He aha ka thermoplastics?
ʻO ka Thermoplastics kekahi papa o nā plastik i paʻa i kekahi mahana, paʻa ma hope o ka hoʻolili ʻana, a hiki ke r.epema keia hana. Hōʻike ʻia ke ʻano molekala e kahi pūhui polymer linear, ʻaʻole i loaʻa nā pūʻulu ikaika, a ʻaʻole i hoʻopaʻa ʻia i ka laina laina intermolecular crosslinking ke 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 (vinyls, 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; keia mokuaina hiki ke repeʻai i nā manawa he nui a loaʻa mau ka plasticity, a ʻo kēia repeʻO ka hoʻololi kino wale nō ka mea i kapa ʻia he thermoplastic. palaki.
Me ka polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyoxymethylene, polycarbonate, polyamide, acrylic plastics, 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".
