He aha ka MHEC?

ʻO Methyl Hydroxyethyl Cellulose (MHEC) he cellulose ether derivative i hoʻohana nui ʻia i nā ʻoihana e like me ke kūkulu ʻana, nā lāʻau lapaʻau, a me nā huahana mālama pilikino.Hoʻohui ʻia ʻo ia ma ka hoʻopili ʻana i ka cellulose me ka ethylene oxide a me ka methyl chloride, ka hopena i kahi hui me nā pūʻulu hydroxyethyl a me methyl i hoʻopili ʻia i ka iwi kuamoʻo cellulose.

Hāʻawi ka MHEC i nā waiwai he nui me nā eter cellulose e like me Hydroxypropyl Methylcellulose (HPMC) a me Hydroxyethyl Methylcellulose (HEMC), me:

1. Ka Paʻa Wai: Loaʻa i ka MHEC ka hiki ke hoʻopaʻa a mālama i ka wai, e hoʻohana pono ai i nā mea hana e like me ka mortar, grouts, a me nā mea hoʻopili tile e pale ai i ka maloʻo ʻana a hoʻomaikaʻi i ka hana.
2. Mānoanoa: Hiki iā ia ke hoʻonui i ka viscosity o nā hoʻoheheʻe wai, he mea maikaʻi ia i nā noi e like me nā pena, nā uhi, a me nā huahana mālama pilikino e hoʻokō ai i ke kūlike i makemake ʻia.
3. Hoʻokūpaʻa: kōkua ʻo MHEC i ka hoʻopaʻa ʻana i nā emulsions a me nā hoʻokuʻu ʻana, e pale i ka hoʻokaʻawale ʻana o ka pae a mālama i ka homogeneity huahana.
4. Hana Kiʻiʻoniʻoni: E like me nā cellulose ethers ʻē aʻe, hiki i ka MHEC ke hana i kahi kiʻiʻoniʻoni lahilahi ke hoʻopili ʻia i nā ʻili, hāʻawi i ka pale a hoʻonui i ka pili.
5. Hoʻomaikaʻi i nā waiwai kahe: Hiki iā ia ke hoʻomaikaʻi i nā hiʻohiʻona kahe o nā formulations, hoʻomaʻamaʻa i ka hana a me ka noi.

Ua koho pinepine ʻia ʻo MHEC no kāna hui pū ʻana o nā waiwai, e like me kona hiki ke hāʻawi i ka mālama wai maikaʻi ʻoiai e mālama ana i ka viscosity haʻahaʻa i hoʻohālikelike ʻia me nā cellulose ethers.He mea kūpono kēia no nā noi kahi e koi ʻia ai ka paʻa wai kiʻekiʻe me ka ʻole o ka hoʻonui nui ʻana i ka viscosity o ka formulation.

ʻO ka Methyl Hydroxyethyl Cellulose (MHEC) he mea hoʻoheheʻe cellulose ether derivative me kahi ākea o nā noi, kahi i waiwai nui ai kona mau waiwai e like me ka mānoanoa, stabilizer, mea mālama wai, a me nā kiʻiʻoniʻoni mua.
