Hoʻohana
Kōkua kānana: Mea hoʻōki i ka hana ʻana, mea hoʻopaʻa; Mea hoʻonui; Mea hoʻoheheʻe; Mea hoʻolaha; Mea hoʻomaikaʻi i ke ʻano; Mea hoʻomānoanoa; Mea mālama wai. Ua kuhikuhi ʻia e ka EEC no ka hoʻomaʻemaʻe ʻana i ka pia. E like me ka mea i kuhikuhi ʻia ma GB 2760-96, ua manaʻo ʻia he kōkua hana. Wahi a nā lula EEC-HACSG, ʻaʻole ia e hoʻohana ʻia i ka meaʻai pēpē. Ma ke ʻano he mea hoʻōki i ka hana ʻana, ma Kina, ua ʻae ʻia e hoʻohana ʻia i nā ʻono pauka me ka hoʻohana nui ʻana o 50g/kg; hiki ke hoʻohana ʻia i ka hau kalima me ka hoʻohana nui ʻana o 40g/kg; hiki ke hoʻohana ʻia i ka kirīmi māmā a me ka pauka momona mea kanu me ka hoʻohana nui ʻana o 20.0g/kg. Ke hana nā hui hydroxyl i loko o ka cellulose macromolecule i nā hopena esterification a i ʻole etherification, hiki ke loaʻa nā huahana pono he nui. ʻO nā esters cellulose i hoʻopili maoli ʻia: cellulose nitrate, cellulose acetate, cellulose acetate butyrate a me cellulose xanthate. ʻO nā cellulose ethers e komo pū ana me: methyl cellulose, carboxymethyl cellulose, ethyl cellulose, hydroxyethyl cellulose, cyanoethyl cellulose, hydroxypropyl cellulose a me hydroxypropyl methyl cellulose, a pēlā aku. Eia kekahi, aia nā hui ester-ether i hui pū ʻia. Hiki ke hoʻohana ʻia ka microcrystalline cellulose i nā ʻoihana e like me nā lole, nā lole, ka hana pia, ka meaʻai, a me ka hana pepa.
ʻO ka maʻamau, ʻoi aku ka haʻahaʻa o ka microcrystalline cellulose no nā huahana maloʻo-hau a ʻoi aku ka nui o ka density no nā huahana i pīpī ʻia. ʻO ka nui o ka makū ma kahi o 5%. Hiki ke hoʻoheheʻe ʻia ka microcrystalline cellulose akā ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai, ʻaʻole hiki ke hoʻoheheʻe ʻia i nā waikawa dilute, nā mea hoʻoheheʻe organik a me nā aila, pehu a hoʻoheheʻe hapa ʻia i loko o nā hopena alkaline dilute. ʻO ka hoʻopuehu ʻana i ka pauka microcrystalline cellulose i loko o ka wai e hua mai i kahi gel a i ʻole paste keʻokeʻo. Koe wale nō nā mea dilute loa, noho paʻa ia no nā makahiki he nui.
ʻŌpala a me ka Hoʻouna ʻana
e like me nā koi o 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.
