Polychlorotrifluoroethylene (PCTFE a i ʻole PTFCE) Pono a me nā noi

ʻO Polychlorotrifluoroethylene (PCTFE a i ʻole PTFCE) he chlorofluoropolymer thermoplastic me ke ʻano mole (CF2CClF)n, kahi i loaʻa ai ka helu o nā ʻāpana monomer i loko o ka molekele polymer.Ua like ia me ka polytetrafluoroethene (PTFE), koe wale no he homopolymer o ka monomer chlorotrifluoroethylene (CTFE) ma kahi o ka tetrafluoroethene.Loaʻa iā ia ka haʻahaʻa haʻahaʻa haʻahaʻa o ka lawe ʻana i ka mahu wai o kēlā me kēia plastik.

Waiwai Loaʻa i ka CTFE ka ikaika tensile kiʻekiʻe a me nā ʻano wela maikaʻi.ʻAʻole hiki ke wela a hiki i ka 175 ° C ke kūpaʻa wela.Loaʻa iā ia ka helu haʻahaʻa o ka hoʻonui wela.ʻO ka mahana hoʻololi aniani (Tg) ma kahi o 45 °C.Loaʻa i ka PCTFE kekahi o ka helu helu oxygen palena kiʻekiʻe loa (LOI).Loaʻa iā ia ka pale kemika maikaʻi.Hōʻike pū ia i nā waiwai e like me ka absorption moisture a me ka hoʻomaʻemaʻe ʻole.ʻAʻole ia e komo i ka mālamalama ʻike ʻia.Ke hoʻokau ʻia i ka radiation kiʻekiʻe, e like me ka PTFE, degradation.Hiki ke hoʻohana ʻia ma ke ʻano he kiʻi ʻoniʻoni.ʻO ka loaʻa ʻana o kahi chlorine atom, ʻoi aku ka nui o ka radius atomika ma mua o ka fluorine, ke keʻakeʻa nei i ka hoʻopili kokoke ʻana i ka PTFE.Loaʻa kēia i kahi helu heheʻe haʻahaʻa ma waena o nā fluoropolymers, ma kahi o 210-215 °C.ʻAʻole kūʻē ka PCTFE i ka hoʻouka ʻana e ka hapa nui o nā kemika a me nā mea oxidizing, kahi waiwai i hōʻike ʻia ma muli o ka loaʻa ʻana o ka fluorine kiʻekiʻe.Eia naʻe, pehu iki ia i loko o nā pūhui halocarbon, nā etera, nā esters a me nā mea hoʻoheheʻe ʻala.He kū'ē ka PCTFE i ka oxidation no ka mea ʻaʻohe ona hydrogen atoms.Hōʻike ʻo PCTFE i kahi manawa dipole mau ma muli o ka asymmetry molekala o kāna ʻāpana hou.He kū pololei kēia manawa dipole i ke axis kaulahao kalapona.Nā noi Loaʻa iā CTFE ka hapa nui o kāna noi ma muli o ʻelua mau waiwai nui: ka hoʻihoʻi ʻana i ka wai a me ke kūpaʻa kemika.Hoʻohana ʻia nā kiʻiʻoniʻoni PCTFE ma ke ʻano he pale pale i ka makū.Aia kēia mau mea:• pale i ka wai i loko o ka hoʻopili ʻana i ka lāʻau lapaʻau,• pale wai-huhū no ka pale ʻana i nā uhi phosphor i nā kukui electroluminescent (ua maʻalahi nā kinikona phosphor i ka makū),• ka pale o ka wai-crystal display (LCD) panels, i pili i ka moisture.Hoʻohana ʻia ia e like me ka uhi a me ka liner prefabricated no nā noi kemika.Hoʻohana pū ʻia ʻo PCTFE no ka laminating ʻana i nā polymers ʻē aʻe e like me PVC, polypropylene, PETG, APET etc. Hoʻohana ʻia ia i nā aniani aniani, nā paipu, nā kīwaha, nā liner tank, O-rings, sila a me nā gaskets.Hoʻohana ʻia ʻo PCTFE no ka pale ʻana i nā ʻāpana uila ma muli o kona kūpaʻa uila maikaʻi loa a me ka repulsion wai.ʻO nā mea hoʻohana ʻē aʻe e pili ana i nā kaapuni paʻi maʻalahi a me ka insulation o nā uea a me nā kaula.ʻIke ʻia nā waxes PCTFE haʻahaʻa-molecular-kaumaha, nā aila a me nā momona i kā lākou noi ma ke ʻano he mea hoʻopaʻa inert a me nā lubricants.Hoʻohana ʻia lākou e like me nā wai kahe gyroscope a me nā plasticizers no nā thermoplastics.
