Hoʻohana
He mea hoʻoheheʻe no nā aila, nā esters cellulose, nā mea pahū, a pēlā aku.
Hāʻawi ʻo EGDA i nā waiwai kahe maikaʻi loa i nā lacquers hoʻomoʻa a me nā enamels a me kahi e hoʻohana ʻia ai nā resins acrylic thermoplastic. He mea hoʻoheheʻe maikaʻi nō hoʻi ia no nā uhi cellulosic a hiki ke hoʻohana ʻia i kekahi mau ʻōnaehana ʻīnika e like me nā ʻīnika pale. Ua loaʻa ka hoʻohana ʻana ma ke ʻano he mea hoʻopaʻa ʻala, a ua hōʻike i nā noi i nā mea hoʻopili wai.
Hiki ke hoʻohana ʻia ka Ethylene glycol diacetate ma ke ʻano he acyl donor no ka hana ʻana o ka waikawa peracetic in situ, i ka wā o ka chemoenzymatic synthesis o ka caprolactone. Hiki ke hoʻohana ʻia ma ke ʻano he precursor no ka enzymatic synthesis o ka poly (ethylene glutarate).
ʻŌpala a me ka Hoʻouna ʻana
220KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
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.
