Is PVC Thermoplastic?
PVC (polyvinyl chloride) he mea thermoplastic.
ʻO Thermoplastics kahi ʻano polymer hiki ke hoʻoheheʻe ʻia a hoʻoheheʻe hou ʻia i nā manawa he nui me ka ʻole o ka hoʻololi ʻana i nā kemika nui. PVC he polimer thermoplastic ka mea i hoʻohana nui ʻia i nā noi like ʻole ma muli o kāna mau waiwai kūʻokoʻa e like me ka lōʻihi, ka maʻalahi, a me ke kūʻē ʻana i nā kemika a me ka wā.
PVC hana ʻia e ka polymerizing vinyl chloride monomer (VCM) ma o ka hana i kapa ʻia ka polymerization hoʻokuʻu. ʻO ka polymer hopena he pauka keʻokeʻo e hiki ke hana ʻia i nā ʻano like ʻole e like me nā paipu, nā pepa, nā kiʻiʻoniʻoni, a me nā profiles.
ʻO kekahi o nā pōmaikaʻi nui o PVC ʻoiai he mea thermoplastic kona hiki ke hana maʻalahi ma o nā ʻano hana like ʻole e like me ka extrusion, injection molding, a me ka puhi ʻana. ʻO kēia ka mea i koho kaulana no ka nui o nā noi e like me ke kūkulu ʻana, automotive, packaging, a me nā mea lapaʻau.
Ma waho aʻe o kāna mau waiwai thermoplastic, PVC loaʻa iā ia kekahi mau hiʻohiʻona kūʻokoʻa e kū ʻokoʻa mai nā thermoplastics ʻē aʻe. ʻo kahi laʻana, PVC ʻO ia ka mea i koho nui ʻia no nā noi kahi e hopohopo ai ka palekana ahi. PVC He kū'ē nō hoʻi ia i ka radiation UV, kahi e kūpono ai no nā noi waho.
Eia naʻe, he mea nui e nānā i kēlā PVC loaʻa pū kekahi mau manaʻo pili kaiapuni e pili ana i kāna hana ʻana a me ka hoʻokuʻu ʻana. ʻO ka hana ʻana o PVC pili i ka hoʻohana ʻana i nā mea ʻawaʻawa e like me VCM, hiki ke loaʻa nā hopena maikaʻi ʻole i ke olakino kanaka a me ke kaiapuni. Eia hou, PVC ʻAʻole hiki ke hoʻoheheʻe ʻia a hiki ke hoʻomau i ke kaiapuni no ka manawa lōʻihi ma hope o ka hoʻolei ʻana.
I ka hopena, PVC He mea thermoplastic i hoʻohana nui ʻia i nā noi like ʻole ma muli o kāna mau waiwai kūʻokoʻa e like me ke kūpaʻa, ka maʻalahi, a me ke kūʻē ʻana i nā kemika a me ka wā. ʻOiai aia kekahi mau manaʻo pili i ke kaiapuni e pili ana i kāna hana ʻana a me ka hoʻokuʻu ʻia ʻana, he koho kaulana ia no nā ʻoihana he nui ma muli o kāna versatility a me ka maʻalahi o ka hana.
Aloha ʻoe, ua makaʻala wale ʻoe i kāu blog ma o Google, a ʻike ʻia he ʻike maoli ia. E makaʻala wau no Brussels. Mahalo wau inā hoʻomau ʻoe i kēia i ka wā e hiki mai ana. Nui ka poʻe e pōmaikaʻi mai kāu kākau ʻana. Ke aloha!
