He aha ka mea PES? Ka nānā 'ana i nā waiwai a me ka ho'ohana 'ana o polyethersulfone
Ma ke kahua o nā mea kemika, "he aha ka mea o ka PES" he nīnau maʻamau, ʻo PES (Polyethersulfone, Polyethersulfone) he polymer thermoplastic kiʻekiʻe, no kona ikaika mechanical maikaʻi a me ke kūpaʻa wela kiʻekiʻe, hoʻohana nui ʻia i nā ʻoihana ʻoihana he nui. Ma kēia ʻatikala, e kūkākūkā mākou i nā kikoʻī i nā waiwai waiwai, nā ʻano hoʻomākaukau a me nā wahi noi nui o PES.
Nā waiwai kumu o PES
ʻO ka PES kahi mea thermoplastic amorphous me ke kūpaʻa wela kiʻekiʻe a me nā waiwai mechanical paʻa. ʻO kona mahana hoʻololi aniani (Tg) ma kahi o 220 ° C, kahi e paʻa ai i nā wahi wela kiʻekiʻe. He kūʻē maikaʻi loa ka PES i ka oxidation a me ka hydrolysis, a hiki iā ia ke pale aku i ka hoʻohaʻahaʻa ʻana i ka wā e ʻike ʻia i nā wahi humid a i ʻole ka wai kiʻekiʻe no nā manawa lōʻihi. Hana kēia mau waiwai i ka PES kūpono no ka hana ʻana i nā ʻāpana no ka hoʻohana ʻana i nā kaiapuni koi.
Hoʻomākaukau a me ka hana ʻana o PES
Hoʻomākaukau maʻamau ka PES e ka polymerization, e pili ana i ka polycondensation o bisphenol A a me 4,4′-dichlorodiphenylsulfone. Hiki i ka mea hana ke hana maikaʻi a hiki ke hanaʻia ma nāʻano likeʻole, e like me ka injection molding, extrusion and thermoforming.PES hiki ke hanaʻia i nā mahana ma waena o 300 ° C a me 350 ° C, e koi ana i ka mea hoʻohana e loaʻa i nā mea hana maikaʻi a me nāʻano mana. ʻOiai paʻakikī ka hana ʻana o ka PES, ʻoi aku ka maikaʻi o nā huahana a me ka hoʻopau ʻana i ka ʻili.
Nā wahi noi nui no PES
Hoʻohana nui ʻia nā mea PES i nā ʻano ʻoihana ma muli o kāna hana maikaʻi loa. I ka ʻoihana uila a me ka uila, hoʻohana nui ʻia ʻo PES e hana i ka insulation uila a me nā mea hoʻohui ma muli o kona ʻano maikaʻi a me ka pale wela, a hoʻohana nui ʻia i ka ʻoihana lāʻau lapaʻau. Ma muli o kona kūpaʻa wela kiʻekiʻe, ka pale hydrolysis a me ke kūʻē kemika, ʻo PES kahi mea kūpono no ka hana ʻana i nā huahana lapaʻau e like me nā mea hana, nā ipu sterilization a me nā kānana.
PES i loko o ka wai
ʻO kahi wahi noi kaulana ʻo ia ka mālama wai. Hoʻohana nui ʻia ʻo PES i ka hana ʻana i nā membrane mālama wai ma muli o kona maikaʻi ʻole kemika a me ke kūpaʻa ʻana i ka haumia. Hoʻohana maʻamau kēia mau membrane i nā ʻōnaehana ultrafiltration a me nā microfiltration a hiki iā ia ke wehe pono i nā mea paʻa i hoʻopaʻa ʻia a me nā microorganism mai ka wai ʻoiai e mālama ana i ka permeability maikaʻi loa a me ka ikaika mechanical. Hōʻike hou kēia noi i ke koʻikoʻi o nā mea PES i nā noi hana kiʻekiʻe.
Nā Pōmaikaʻi Kaiapuni o PES
I kēia ao ʻike kaiapuni i kēia lā, aia nā waiwai waiwai o PES i ka hiʻohiʻona: He lōʻihi ke ola o ka PES a me ka paʻa maikaʻi, e hōʻemi ana i ke alapine o ka hoʻololi ʻana i nā mea a no laila e hoʻopau ʻia, a ʻo ke kaʻina hana e pili ana i ke kaiapuni, ʻaʻohe pono o nā solvents.
Ka hopena
Mai nā kikoʻī kikoʻī o kēia pepa, hiki iā mākou ke hoʻoholo ʻo PES kahi mea thermoplastic hana kiʻekiʻe me nā waiwai maikaʻi loa a me kahi ākea o nā noi. Inā ma ke kahua o ka uila a me ka uila, nā mea lapaʻau a i ʻole ka mālama wai, ua hōʻike ʻo PES i nā pono kūʻokoʻa. No ka poʻe heluhelu e makemake ana e ʻike "he aha ka PES i hana ʻia ai", ʻo PES kahi mea koʻikoʻi me ka nui o nā mea hiki a me nā noi he nui, a e hoʻomau i ka hana nui i ka hoʻomohala ʻana i ka ʻoihana e hiki mai ana.
