1,2,4-Benzenetricarboxylicanhydride CAS:552-30-7

Hana ʻo 1,2,4-Benzenetricarboxylic anhydride (BTCA) i nā hana he nui ma nā ʻoihana like ʻole ma muli o kona mau waiwai like ʻole. Ma ke kahua o ka kemika polymer, hana ia ma ke ʻano he mea hoʻopili a me ka monomer reactive i ka hana ʻana o nā resins thermoset, e like me ka polyester a me nā resins epoxy. Loaʻa kēia mau resins i nā noi i nā uhi, nā mea hoʻopili, nā composites, a me nā hui hoʻoheheʻe, e hāʻawi ana i ka ikaika o ka mea, ke kūpaʻa wela, a me ke kūpaʻa kemika. Eia kekahi, hoʻohana ʻia ʻo BTCA i ka hana ʻana o nā polymers hana kiʻekiʻe e like me polyimides, kahi e lawelawe ai ma ke ʻano he poloka hale koʻikoʻi. Hoʻonui kona hoʻokomo ʻana i loko o nā kaulahao polymer i ko lākou kūpaʻa wela, ka ikaika mechanical, a me nā waiwai dielectric, e kūpono ai no nā noi i nā electronics, aerospace, a me nā kiʻiʻoniʻoni kūikawā. I ka hoʻokumu ʻana o nā uhi a me nā linings pale corrosion, hoʻokani ʻo BTCA i kahi kuleana koʻikoʻi ma ke ʻano he mea hoʻōla a me ka crosslinker. Ke hui pū ʻia me nā ʻōnaehana epoxy a polyurethane paha, hoʻonui ia i ke kūpaʻa kemika a me ka hoʻopili ʻana o nā uhi i hoʻohana ʻia no ka pale ʻana i nā ʻili metala i nā noi kai, ʻoihana, a me nā ʻoihana. Eia kekahi, loaʻa iā ia ka noi ma ke ʻano he mea chelating i nā kaʻina hana mālama wai. ʻO kona hiki ke hoʻokaʻawale i nā iona metala e kōkua i ka pale ʻana i ka hoʻokumu ʻana o ka unahi a me ka palaho i loko o nā ʻōnaehana hoʻolaha wai, e kōkua ana i ka hoʻomaikaʻi ʻana i ka maikaʻi o ka wai a me ke ola lōʻihi o ke kahua. Eia kekahi, lawelawe ʻo BTCA ma ke ʻano he mea mua i ka synthesis o nā mea waena lāʻau lapaʻau a me nā kemika kūikawā. ʻO kona reactivity a me nā hui hana e lilo ia i mea waiwai no ka hoʻomohala ʻana i nā hui kemika maʻamau i hana ʻia no nā koi ʻoihana a me nā lāʻau lapaʻau. Eia kekahi, hoʻohana ʻia ia i ka hana ʻana o nā mea pale ahi a me nā mea hoʻohui pale wela no nā plastics a me nā textiles, e kōkua ana i ka hoʻonui ʻana i ka palekana ahi a me ke kūpaʻa wela i nā noi mea kūʻai aku a me nā ʻoihana. Ma keʻano holoʻokoʻa, ʻo nā noi like ʻole o 1,2,4-benzenetricarboxylic anhydride e pili ana i ka kemika polymer, nā polymers hana kiʻekiʻe, nā uhi pale corrosion, ka mālama ʻana i ka wai, nā lāʻau lapaʻau, nā mea pale ahi, a me nā kemika kūikawā. ʻO kona mau waiwai versatile e kōkua i ka hoʻomaikaʻi ʻana i ka hana o nā mea, pale aku i ka hōʻino ʻana, a hiki i ka hana ʻana o nā mea holomua ma nā ʻoihana he nui.
