He aha ka PFA?
ʻO ka inoa Pelekane oPFAʻO ia: Polyfluoroalkoxy, ka inoa Pākē: tetrafluoroethylene - perfluorinated alkoxy vinyl ether copolymer (ʻike pū ʻia me: perfluorinated alkylates, soluble polytetrafluoroethylene)PFAresin he mea hou melt-processable fluoroplastics, PFA, FEP, PTFE kemika waiwai like, akā, FEP hiki ke hoʻohana wale ma lalo o 200 degere, PTFE hiki ole injected.
1、Kamaha kikoʻī: 2.13-2.167g/cm3
2 、 Ka hoʻohaʻahaʻa ʻana: 3.1-7.7%
3 、 Ke ana wela: 350-400 ℃
4、ʻO ka helu heheʻe o PFA ma kahi o 580F a ʻo ka mānoanoa he 2.13- 2.16g/cc (g/cm3).
ʻO nā hiʻohiʻona a me nā hoʻohana nui o PFA
ʻO ka PFA ka mea maʻamau i kapa ʻia ʻo PTFE fusible, a ʻo kāna mau waiwai like ʻole ka luna o nā fluoroplastics, a ua like kona hoʻohana ʻana me FEP.Hoʻohana nui ia i ka ʻoihana semiconductor, a me ka lāʻau lapaʻau, kemika a me ka anti-corrosion, automotive a me nā māla ʻē aʻe.
Loaʻa ka PFA ma ke ʻano pellet no ka hoʻoheheʻe ʻana a me ka extrusion, ʻano pauka no ka hoʻoheheʻe ʻana a me ka uhi ʻana, a me nā huahana semi-finished e like me nā kiʻiʻoniʻoni, nā lau, nā koʻokoʻo a me nā paipu.ʻO nā resins PFA i hoʻolaha ʻia ma ka mākeke ʻAmelika ʻo Teflon mai DUPOut, Neoflon brand mai Daikin, Hthen brand mai Ansimont, a me Hostafl brand mai HOechst Celanese.
1, ʻO nā hoʻohana nui oPFA.
①.He kūpono no ka hana ʻana i nā ʻāpana pale corrosion, nā ʻāpana pale pale, nā sila, nā ʻāpana insulation a me nā ʻāpana lāʻau lapaʻau.
②.ʻO ka uwea wela wela a me ka hoʻokaʻawale ʻana i ke kaula, nā mea hana anti-corrosion, nā mea hoʻopaʻa paʻa, nā ʻōpala a me nā pahu valve, a me nā ipu kemika.
2、Hoʻokumu i ka hana
①.ʻO nā mea Crystalline, liʻiliʻi ka hoʻoheheʻe wai.Hiki ke hana ʻia i huahana e nā ʻano hana thermoplastic maʻamau.
②.ʻAʻole hiki ke hoʻoneʻe ʻia, maʻalahi loa ka decompose, hoʻopuka ka decomposition i ke kinoea corrosive.ʻAʻole pono ka mahana o ka hoʻoheheʻe ʻana ma mua o 475 degere, pono e hoʻomehana ʻia ka mold i 150-200 degere, a ʻo ka ʻōnaehana ninini e haʻahaʻa haʻahaʻa i ke kahe waiwai.
③.ʻO nā granule translucent, hoʻoheheʻe a me ka hoʻoheheʻe ʻana.ʻO ka mahana hoʻoheheʻe 350-400 degere, ma luna o 475 degere he maʻalahi ke hoʻoneʻe ʻia a i ʻole nā pua.A e hoʻomanaʻo e ʻoi aku ka paʻakikī o ka demold.
④.No ka mea, he hopena koʻikoʻi ka mea hoʻoheheʻe ʻia i ka metala, ka hana lōʻihi, pono ka hoʻoheheʻe chromium plating lapaʻau.
Hana waiwai
1、 PFA he copolymer o kahi liʻiliʻi o ka perfluoropropyl perfluorovinyl ether a me ka polytetrafluoroethylene.Hoʻonui ʻia ka hoʻoheheʻe hoʻoheheʻe ʻana, hoʻemi ʻia ka viscosity o ka hopena, ʻoiai ʻaʻole loli ka hana i hoʻohālikelike ʻia me PTFE.Hiki ke hana pololei ʻia kēia resin i nā huahana e ke ʻano hana hoʻoheheʻe thermoplastic maʻamau.
2, ka mahana hoʻohana lōʻihi - 80 - 260 degere, loaʻa i ke kūpaʻa kemika maikaʻi loa, ka pale ʻana i ka corrosion i nā kemika āpau, ka mea haʻahaʻa haʻahaʻa o ka friction i loko o ka plastic, aia nā waiwai uila maikaʻi loa, ʻaʻole i hoʻopilikia ʻia kona insulation uila e ka mahana, kapa ʻia ka "plastic King".
3, kona kūpaʻa kemika a me ka PTFE like, ʻoi aku ka maikaʻi ma mua o ka vinylidene fluoride.
4, ʻoi aku ka maikaʻi o kona kūpaʻa ʻana a me ka ikaika paʻakikī ma mua o ka PTFE, ka ikaika tensile kiʻekiʻe, elongation a hiki i 100-300%.ʻO nā waiwai dielectric maikaʻi, maikaʻi loa ka pale ʻana i ka radiation.
5、Non-toxic: physiologically inert, hiki ke hoʻokomo i loko o ke kino kanaka.
