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 ka homopolymer o ka monomer chlorotrifluoroeth...Heluhelu hou aku -
He aha ka Fluoropolymer?
ʻO ka Fluoropolymer ka mea maʻamau ka polymer olefinic i loaʻa i nā monomers olefinic hapa a i ʻole fluorinated piha e like me vinylidene fluoride (CH2¼CF2) a me tetrafluoroethylene (TFE) (CF2¼CF2).Ua uhi ʻia kēia mau polymers i nā kikoʻī nui i kekahi mau kuhikuhi.ʻO ka polyme fluorinated kūikawā hou aku...Heluhelu hou aku -
Hoʻohālikelike ma waena o ka PTFE a me ka PFA Processing
No kekahi mau makahiki, ua hoʻokani nui nā fluoropolymers i nā ʻoihana kemika a me nā ʻoihana like e pale aku i nā mea kanu a me nā mea hana mai ka hoʻouka ʻana i nā kemika e kahi ākea ākea o ka media.ʻO kēia no ka mea hāʻawi lākou i ke kūʻokoʻa kemika maikaʻi loa a me ka paʻa wela ma mua o o ...Heluhelu hou aku -
ʻO ke kūkulu hale me ka hoʻolālā ETFE
Ua hoʻohana ʻia nā hale tensile no nā millennia.I ka wā e makemake ai ka poʻe ʻōiwi i ka hale maʻalahi a maikaʻi hoʻi, ʻo nā lole i hana ʻia mai nā ʻili holoholona a me nā mea maʻalahi hiki ke lawe ʻia ka hopena kūpono loa.Ma ka Roman Colosseum, kahi Velarium hiki ke hoʻihoʻi ʻia i hāʻawi i ka malu no ...Heluhelu hou aku
