Hydroxypropyl starch etera-HPS
1. Ka inoa kemika: Hydroxypropyl starch ether
2. inoa Pelekane: Hydroxypropylstarch etera
3. ʻŌlelo Pelekane: HPS
4. Māmā mole: C7H15NO3 Molecular mass: 161.20
5. Keʻano o ka hoʻomākaukauʻana: Hydroxypropyl starch he starch i hoʻololiʻia, i hoʻololiʻia e ka propylene oxide a me ka starch e pani i ka hui hydroxyl i loko o ka hale macromolecule starch e lilo iʻano o ka starch etherified.
6. Nā waiwai kino: keʻokeʻo (colorless) pauka me ka maikaʻi fluidity a me ka wai maikaʻi solubility, kona aqueous solution mea maopopo a me ka waihoʻoluʻu, a me ka maikai paʻa. Paʻa ia i ka waikawa a me ka alkali, ʻoi aku ka haʻahaʻa o ka mahana sintering ma mua o ka starch maoli, a ʻoi aku ka paʻa o ka loli o ka viscosity wela a me ke anu ma mua o ka starch maoli. ʻAʻohe hopena o ka hui ʻana me ka paʻakai a me ka sucrose i ka viscosity. Ma hope o ka etherification, ua hoʻomaikaʻi ʻia ka paʻa o ka hoʻoheheʻe hau a me ka ʻike.
7. Nā waiwai kemika: nā waiwai o ka starch derivatives me ka hydroxypropyl substituents, ka glucose unit constituting starch he 3 hydroxypropyl pūʻulu hiki ke hoʻololi, no laila hiki ke loaʻa nā huahana me nā pae like ʻole.
8. Nā hōʻailonaʻenehana Nānā: ka pauka keʻokeʻo, maʻalahi ke komo i ka wai
Solubility: Hiki ke hoʻoheheʻe i ka wai a lilo i mea hoʻonā akaka
Viscosity (5% wai wai, 20℃): 500-20000 mPa.s
PH waiwai (2% aqueous solution): 8-10
9. Manao
1) I loko o ka ʻoihana meaʻai hydroxypropyl starch, hiki ke hoʻohana ʻia ka hydroxypropyl starch ma ke ʻano he mānoanoa, hiki ke hoʻohana ʻia ka hydroxypropyl starch ma ke ʻano he mea hoʻomaha, a hiki ke hoʻohana ʻia ka hydroxypropyl starch ma ke ʻano he mea hoʻopili.
2) ʻOihana pepa hydroxypropyl starch: hoʻohana ʻia ka hydroxypropyl starch no ka nui o loko o ka pepa, hoʻohana ʻia ka hydroxypropyl starch no ka nui o ka ʻili, hydroxypropyl starch e hana i ka paʻi ʻana i ka ʻīnika, hydroxypropyl starch e hana like, hydroxypropyl starch E hoʻomaʻamaʻa i ke kiʻiʻoniʻoni, hydroxypropyl starch e hōʻemi i ka ʻai ʻīnika, a hiki i ka hydroxypropyl starch ke huki lauoho.
3) Hydroxypropyl starch textile ʻoihana: hydroxypropyl starch hiki ke hoʻohana ʻia e like me ka nui o ka warp, hydroxypropyl starch hiki ke hoʻomaikaʻi i ke kūpaʻa abrasion i ka wā o ka ulana ʻana, hydroxypropyl starch a me ka ulana pono ʻana, hydroxypropyl starch me ke kiʻekiʻe o ka hoʻololi ʻana o ka hydroxypropyl starch Hiki ke hoʻohana ʻia ka starch base e like me ka paʻi paʻi. .
4) Hydroxypropyl starch ʻoihana lāʻau lapaʻau: Hiki ke hoʻohana ʻia ka hydroxypropyl starch ma ke ʻano he mea hoʻokaʻawale no nā papa, a hiki ke hoʻohana ʻia ka hydroxypropyl starch ma ke ʻano he plasma bulking agent.
5) Hoʻopaʻa ka māko hydroxypropyl i ka pā pūnāwai, hoʻomaikaʻi ʻo hydroxypropyl starch i nā kūlana luawai, pale ka hydroxypropyl starch i ka hāʻule ʻana, a ʻo ka hydroxypropyl starch e hoʻopili i nā ʻoki ʻoki.
6) ʻO ka hydroxypropyl starch i kēlā me kēia lā ʻoihana kemika: hoʻohana ʻia ka hydroxypropyl starch i ka ʻoihana kemika i kēlā me kēia lā a hoʻohana ʻia ka hydroxypropyl starch ma ke ʻano he binder, suspending agent a me ka mānoanoa i nā mea hoʻonaninani a i ʻole nā uhi.
7) Hydroxypropyl starch Eia kekahi, hiki ke hoʻohana ʻia ka hydroxypropyl starch ma ke ʻano he mea hoʻopaʻa no nā mea kūkulu hale, he gelling agent no ka hydroxypropyl starch coatings a i ʻole nā wai kūlohelohe, a me ka hydroxypropyl starch.
8) ʻOihana meaʻai: Hiki ke hoʻohana ʻia e like me ka mea hoʻopili, thickener, suspending agent e hoʻonui i ka paʻa.
