ʻAkika Trans-Butenedioic
(ʻAkika Fumaric)
Kikoʻī:Loaʻa i ka waikawa trans-butenedioic ka hana bacteriostatic a me ka antiseptic. Hiki ke hoʻohana ʻia ma ke ʻano he acidulant, acidity regulator, acidifier;
Nā Waiwai:Pauka keʻokeʻo ʻala ʻole a i ʻole, me ka ʻawaʻawa kūikawā e like me ka ikaika o 1.5 mau manawa o ka waikawa citric. Hiki ke hoʻoheheʻe ʻia i loko o ka ethanol (5.76g/100g,30°c), hoʻoheheʻe iki ʻia i ka wai (0.63g/100ml,25°c) a me ka ether, a hoʻoheheʻe iki ʻia i loko o ka chloroform. ʻAʻohe ona hygroscopicity, a e sublime ma 200°c. Kikowaena paila: 290°c (decompose). E lilo ia i maleic anhydride ma 230°c, a e hoʻopuka i ka waikawa DL-malic inā hoʻolapalapa ʻia me ka wai.
Hoʻohana:Loaʻa i ka waikawa Trans-butenedioic ka hana bacteriostatic a me ka antiseptic. Hiki ke hoʻohana ʻia ma ke ʻano he acidulant, acidity regulator, acidifier, thermal-oxidative resist auxiliary, curing accelerant a me ka mea ʻala. Hoʻohana nui ʻia i ka hana ʻana i nā ʻano mea inu carbonic acid like ʻole, waina, mea inu paʻa i hoʻopaʻa ʻia, ice cream a me nā meaʻai anuanu a me nā mea inu ʻē aʻe. Hiki iā ia ke pani i ka malic acid, citric acid, no ka mea, ʻo kona acidity degree he 1.5 mau manawa o ka citric acid. Hiki ke hoʻohana ʻia ka fumaric acid ma ke ʻano he PHAR intermediate a me ka optical bleaching agent, hoʻohana ʻia hoʻi i ka hana ʻana i ka unsaturated polyester resin.
1.ʻOi aku ma mua o 10 mau makahiki o ka ʻike me ka hōʻoia ʻia ʻo ISO,
2. Hale hana o ka ʻono a me ka hoʻohuihui ʻana i ka mea ʻono, nā lama ponoʻī o Tianjia,
3. Noiʻi ma ka ʻIke mākeke a me ka hahai ʻana i ke au,
4. Hoʻolaha manawa kūpono a me ka hoʻolaha ʻana i nā huahana wela,
5.Reliable & E hahai pono i ke kuleana o ka ʻaelike a me ka lawelawe ma hope o ke kūʻai aku,
6. ʻOihana ma ka lawelawe Logistic International, nā palapala hoʻokō kānāwai a me ke kaʻina hana nānā ʻaoʻao ʻekolu.
