He aha ka BPADA CAS 38103-06-9?

ʻO 4,4'-(4,4'-ISOPROPYLIDENEDIPHENOXY)BIS(PHTHALIC ANHYDRIDE) (BPADA) kahi monomer polyetherimide i hoʻomākaukau ʻia a me kahi ʻano polyimide fusible. ʻAʻole wale ʻo 4,4'-(4,4'-ISOPROPYLIDENEDIPHENOXY)BIS(PHTHALIC ANHYDRIDE) e mālama i nā waiwai maikaʻi loa o ka polyimide akā loaʻa pū kekahi hana hana o nā plastic plastic maʻamau. Eia kekahi, haʻahaʻa ke kumukūʻai o 4,4'-(4,4'-ISOPROPYLIDENEDIPHENOXY)BIS(PHTHALIC ANHYDRIDE) a kūpono no ka hoʻomākaukau ʻana i nā huahana paia lahilahi a me nā huahana paʻakikī.

1. Hoʻohui i nā huahana polyimide hana kiʻekiʻe (PI) no nā kumu laulā

ʻO kēia ka hoʻohana maʻamau a koʻikoʻi loa o BPADA. Hoʻohui ʻia ka BPADA me nā monomers diamine maʻamau e like me 4,4' -diaminodiphenyl ether (ODA) e hana i ka polyimide e hoʻohui i ka "pale wela a me ka maʻalahi o ka hana ʻana". ʻO kēia ʻano mea PI, ma muli o ke alo o nā pilina ether a me nā hui isopropyl i loko o kona ʻano molekala, mālama i ke kūpaʻa wela kiʻekiʻe o PI (mahana lawelawe lōʻihi 180-220 ℃). He maʻalahi hoʻi ka hana ʻana o BPADA i nā kiʻiʻoniʻoni, nā papa, a pēlā aku ma mua o ka PI maʻamau, a hoʻohana pinepine ʻia i:

1) Nā ʻāpana hoʻokaʻawale kumu ma ke kahua uila: ʻO ke kiʻiʻoniʻoni kumu a me ke kiʻiʻoniʻoni uhi no ka hana ʻana i nā papa kaapuni paʻi maʻalahi (FPC), a me ka pepa hoʻokaʻawale pale wela kiʻekiʻe/varnish hoʻokaʻawale no nā motika a me nā mea hoʻololi, e hoʻokō i nā koi "miniaturization + temperature resistance" o nā ʻāpana uila, e like me ka pale ʻana o ka insulation kūloko no nā mea uila mea kūʻai aku a me nā motika ʻoihana.

2) Nā ʻāpana ʻoihana maʻamau e kū i ka mahana kiʻekiʻe: Hana ʻia i loko o nā papa PI a me nā paipu, hoʻohana ʻia lākou no nā pale pale wela kiʻekiʻe a puni nā mīkini kaʻa a me nā ʻāpana kūloko o nā mīkini hale (e like me nā umu a me nā umu microwave). Hiki iā lākou ke kū i nā mahana ma luna o 150℃ no ka manawa lōʻihi, a kū i ka ʻelemakule a me ka nahā.

2. Hoʻololi i nā resins maʻamau e hoʻonui i ka hana

I ka hoʻololi ʻana o ka resin maʻamau, ʻo BPADA, ma ke ʻano he "monomer hoʻoikaika wela", hoʻohana pinepine ʻia e hoʻomaikaʻi i ka hana o nā resins epoxy a me nā resins phenolic a hoʻonui i kā lākou mau hiʻohiʻona noi:

1) Hoʻololi ʻana o ka resin Epoxy: Ke hui pū ʻia me ka resin epoxy maʻamau, hoʻonui ka BPADA i ke kūpaʻa wela kiʻekiʻe o ka resin (e hoʻonui ana i ke kūpaʻa wela lōʻihi o ka resin i hoʻōla ʻia mai 120 ℃ a ʻoi aku ma mua o 180 ℃), a hoʻohana ʻia no ka hoʻopaʻa ʻana i nā kaola nui o nā lau turbine makani a ma ke ʻano he uhi insulating no nā kaula uila kiʻekiʻe, e hoʻokō ana i nā koi hoʻohana lōʻihi ma nā wahi waho a ʻoihana paha.

2) Nā mea maka kumu no nā uhi/mea hoʻopili e kū i ke ana wela kiʻekiʻe: Ma ke ʻano he ʻāpana hoʻopili o nā uhi a me nā mea hoʻopili, ua hui pū ʻia ʻo BPADA me nā resins phenolic a me nā resins silicone e hana i nā uhi e kū i ke ana wela kiʻekiʻe no nā lako ʻoihana (e like me nā uhi anti-corrosion a me nā uhi e kū i ka wela no nā paia o loko o nā paila a me nā pipelines), a me nā mea hoʻopili e kū i ke ana wela kiʻekiʻe e hoʻōla i ka mahana o ka lumi no nā metala a me nā keramika. Hoʻohana pinepine ʻia kēia mau mea no ka pale ʻana a me ka hoʻopaʻa ʻana i nā lako mechanical a me nā kemika.
