Wehewehena:
He hui organik ka waikawa Isophthalic me ke ʻano C6H4(CO2H)2. ʻO kēia mea paʻa kala ʻole he isomer o ka waikawa phthalic a me ka waikawa terephthalic. Hoʻohana ʻia kēia mau waikawa dicarboxylic ʻala ma ke ʻano he precursors (ma ke ʻano o acyl chlorides) i nā polymers koʻikoʻi kālepa, e laʻa me ka mea pale ahi ʻo Nomex. I kāwili ʻia me ka waikawa terephthalic, hoʻohana ʻia ka waikawa iso phthalic i ka hana ʻana i nā resins no nā ʻōmole inu. Hana ʻia ka polymer hana kiʻekiʻe poly benzimidazole mai ka waikawa iso phthalic.

Hoʻohana
Hoʻohana ʻia ka waikawa Isophthalic ma ke ʻano he waena no nā polyesters unsaturated hana kiʻekiʻe, nā resins no nā uhi, nā pena paʻa kiʻekiʻe, nā ʻaʻahu gel a me ka mea hoʻololi o ka polyethylene terephthalate no nā ʻōmole. Hana ia ma ke ʻano he precursors no ka mea pale ahi nomex a hoʻohana ʻia hoʻi i ka hoʻomākaukau ʻana o ka polymer polybenzimidazole hana kiʻekiʻe. Hoʻohana ʻia hoʻi ia ma ke ʻano he mea hoʻokomo no ka hana ʻana i nā mea insulation.
Hoʻohana nui ʻia ka Purified Isophthalic Acid (PIA) ma ke ʻano he waena no ka UPR hana kiʻekiʻe, nā resins no nā uhi ʻana, nā pena paʻa kiʻekiʻe, nā ʻaʻahu gel, ka mea hoʻololi o PET no nā ʻōmole.
Ka hoʻopili ʻana
25KG/ʻeke a i ʻole e like me nā koi a ka mea kūʻai aku.
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
