Hydroxyethyl methyl cellulose

Ua hoʻomākaukau ʻia ka Hydroxyethyl methul cellulose (HEMC) ma ka hoʻolaha ʻana i ka ethylene oxide substituent i loko o ka methyl cellulose (MC). ʻOi aku ka maikaʻi o ka hoʻomanawanui ʻana o ka paʻakai ma mua o ka polymer unmodified, a ʻoi aku ke kiʻekiʻe o ka mahana o ka methyl hydroxyethyl cellulose ma mua o ka methyl cellulose.

.. ʻOihana

1. Hōʻailona: Ke keʻokeʻo a i ʻole nā ​​keʻokeʻo like paha, ʻaʻohe moʻo mīkini mīkini, ʻona a pono ʻole

2. Ke aniani gel (℃) ： 60-90

3. Waiwai wai （Wt%）: ≤5.0

4. ʻIke lehu （Wt%）: ≤5.0

5.HP: 5.0-8.0

6. ʻānō: ≥80 Mesh

7. ʻO ka hopohopo （mPa.s, 2% aileous solution, 20 ± 0.2 ℃）: 100000-20000

Ⅱ.Main hana hana

1. Hoʻopau: hiki ke hoʻoneʻe ʻia ke kuhi H H ma ka HEMC i ka wai anuanu a me ka wai wela, ʻoiai ke hoʻohālike ʻia ka Lē hiki ke hoʻoheheʻe ʻia i ka wai anu, aʻo ka HEMC ʻaʻole i līlei ʻia i ka hapa nui o nā organikiki. Holo ʻia ka papa i ka HEMC i ka wai anuanu ʻaʻole i lihilahi. Eia naʻe, hiki ke hoʻopau koke iā ia ma ka hoʻoponopono ʻana i kāna waiwai pH i ka 8-10

2. ʻO ke kūpaʻa PH: he liʻiliʻi ka waiwai pH ma ke kaha o 2-12 viscosity hoʻololi, ma ʻō aku o kēia pae ʻana e emi ai ka viscosity

3. Loaʻa nā ʻano o ka HEMC o ka mānoanoa, ka hoʻokuʻu ʻana, ka hoʻopuehu ʻana, ka hoʻopili ʻana, ka emulsification, ke kiʻi ʻoniʻoni a me ka paʻa ʻana o ka wai, a ʻoi aku ka ikaika o ka hiki o ka paʻa ʻana o ka wai ma mua o ka methylcellulose. ʻO ke kūpaʻa viscosity, ʻoi aku ke kūpale me ka puehu ʻana ma mua o ka hydroxyethyl cellulose

. Hoʻohana a me ke akahele

Hoʻohana nui ka HEMC i ka pani ʻana i ka wai me ka mea i hoʻopili ʻia i ka wai, hana a me nā mea hale kūkulu, ka paʻi ʻana i ka inika, ka hoʻokaʻa aila, a laila

Ⅳ. Pūʻolo a me kahi waiho

1. Loaʻa i kēia huahana ka pepa ʻikepili palekana e pili ana a me ka ʻikepili palapala ʻae palekana

Hoʻopili ʻia kēia huahana ma ka pepa 25 kraft pepa a me ka ʻeke kiʻi pepa i hoʻonani ʻia

3.Store i kahi kahi ma kahi, mālama i ka hoʻohuihui i ka umu-hōʻoia
