PPO mea mai SIKO
ʻO ka polyphenylene oxide a i ʻole polyethylene ether Ua ʻike ʻia ʻo polyphenylene oxide a i ʻole polyphenylene ether, he resin thermoplastic kūpaʻa kiʻekiʻe.
Nā ʻano a me nā noi
ʻO ka PPO kahi plastik ʻenehana thermoplastic me ka hoʻokō piha maikaʻi loa, ka insulation uila koʻikoʻi a me ke kū ʻana o ka wai, a me ke kūpaʻa maikaʻi.
1, nā waiwai dielectric o nā plastic engineering mua
PPO resin molecular structure me ka ʻole o nā pūʻulu polar ikaika, nā waiwai uila paʻa, hiki ke mālama i nā waiwai uila maikaʻi ma kahi ākea o ka mahana a me ka pinepine.
① Dielectric mau: 2.6-2.8 ka mea li'ili'i loa i loko o ka 'enekinia plastics ② Tangent o dielectric poho Angle: 0.008-0.0042 (aneane 'a'ole pili i ka wela, humidity a me ka pinepine) ③ Volume resistivity: 1016 ka mea kiʻekiʻe loa ma ka 'enekinia plastics.
2, maikaʻi mechanical a me thermal waiwai o PPO kaulahao mole, loaʻa i ka nui o ka aromatic apo hoʻolālā, molecular kaula sensitivity ikaika, resin mechanical ikaika kiʻekiʻe, maikaʻi creep kū'ē, hoʻololi wela liʻiliʻi loa.He kiʻekiʻe ka pale wela o ka PPO, ka mahana hoʻololi aniani a hiki i 211 ℃, ka helu heheʻe 268 ℃.
3, ʻo ka PPO maikaʻi loa ka pale ʻana i ka wai he resin non-crystalline, ma ke ʻano wela maʻamau, ʻoi aku ka liʻiliʻi o ka neʻe ʻana o ka molekala, ʻaʻohe hui polar nui i ke kaulahao nui, ʻaʻole hiki i ka manawa dipole ke pole, maikaʻi loa ke kū ʻana o ka wai, ʻo ia ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa. o nā ʻano ʻenekinia plastik.He liʻiliʻi ka hoʻohaʻahaʻa ʻana o kona mau waiwai kino ma hope o ka hoʻoluhi ʻana i ka wai wela no ka manawa lōʻihi.
4, ʻO ka helu oxygen o PPO hoʻopau ponoʻī he 29, ʻo ia ka mea hoʻopau ponoʻī, a ʻo ka helu oxygen o ka polyethylene hopena kiʻekiʻe he 17, ʻo ia ka mea inflammable.ʻO ka hui pū ʻana o ia mau mea ʻelua o ka flammability haʻahaʻa.I ka hana ʻana i ka PPO pale ahi, ʻaʻohe pono e hoʻohui i ka halogen flame retardant, hoʻohui i ka phosphorus-containing flame retardant dose hiki ke hiki i ka maʻamau UL94.E hoemi i ka pollution i ke kaiapuni.
5, haʻahaʻa shrinkage rate, maikaʻi dimensional paʻa;Non-toxic, low density 6, dielectric resistance and light resistance PPO acid, alkali and detergent and other basic corrosion, ma lalo o ke kūlana o ke koʻikoʻi, mineral aila a me ketone, ester solvents e hana stress māwae;Hiki ke hoʻoheheʻe a hoʻoheheʻe ʻia nā mea hoʻoheheʻe organik e like me aliphatic hydrocarbons, halogenated aliphatic hydrocarbons a me aromatic hydrocarbons.
ʻO ka nāwaliwali o ka PPO he pale māmā maikaʻi ʻole, lōʻihi ma lalo o ka lā a i ʻole ka hoʻohana ʻana i ke kukui fluorescent e hana i ka discoloration, kala melemele, ʻo ke kumu ke hiki i ke kukui ultraviolet ke hoʻokaʻawale i ke kaulahao o ka ether aromatic.Pehea e hoʻomaikaʻi ai i ka pale māmā o PPO e lilo i kumuhana.
Hoʻoholo ka hana o PPO i ke kahua a me ke ʻano o ka noi:
①MPPO liʻiliʻi liʻiliʻi, maʻalahi e hana, thermal deformation wela i 90-175 ℃, aia nā ʻano kikoʻī like ʻole o nā waiwai, ke kūpaʻa maikaʻi maikaʻi, kūpono no ka hana ʻana i nā lako keʻena, nā lako hale, nā pahu kamepiula, nā chassis a me nā ʻāpana kikoʻī.
② MPPO dielectric mau a me ka dielectric poho Angle tangent i loko o ka elima nui 'enekinia plastics i ka haʻahaʻa, 'o ia hoʻi, ka maikai insulation, a me ka wela wela maikai, kupono no ka oihana uila.He kūpono no ka hana ʻana i nā ʻāpana insulating uila, e like me ka coil frame, tube holder, control shaft, transformer shield sleeve, relay box, insulating pillar a pēlā aku, i hoʻohana ʻia i nā kūlana pulu a hoʻouka.
③ Hiki i ka MPPO ke kū i ka wai a me ka wela, kūpono no ka hana ʻana i nā mika wai, nā paila wai a me nā paipu wili i hoʻohana ʻia i nā hale lole lole e pono ai nā mea kūʻai aku paʻa no ka kuke ʻana.ʻO nā paipu yarn i hana ʻia me MPPO he lōʻihi ke ola lawelawe.
④ ʻAʻole pili ka dielectric mau a me ka dielectric loss Angle tangent o MPPO e ka wela a me ka helu pōʻai i loko o ka ʻenekinia plastics, a maikaʻi ke kūpaʻa wela a me ke kūpaʻa dimensional, i kūpono no ka ʻoihana uila.
