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 starch macromolecule structure 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 waika a me ka alkali, ʻoi aku ka liʻiliʻi o ka mahana sintering ma mua o ka starch maoli, a ʻoi aku ka paʻa o ka hoʻololi ʻana o ka viscosity wela a me ke anuanu 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 hōʻailona ʻenehana Nānā: ka pauka keʻokeʻo, maʻalahi ke komo i ka wai

Solubility: Hiki ke hoʻoheheʻe i loko o 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 ke adhesive, thickener, suspending agent e hoʻonui i ka paʻa.
