He aha ka HEMC?

ʻO ka Hydroxyethyl Methylcellulose (HEMC) he cellulose ether derivative i hoʻohana mau ʻia ma ke ʻano he mānoanoa mānoanoa, stabilizer, a me ka hoʻohui wai paʻa i loko o nā ʻoihana like ʻole, ʻo ia hoʻi i ke kūkulu ʻana, nā lāʻau lapaʻau, a me nā huahana mālama pilikino. E like me ka Hydroxypropyl Methylcellulose (HPMC), ua hoʻohui ʻia ʻo HEMC ma ka mālama ʻana i ka cellulose me ka ethylene oxide a me ka methyl chloride, ka hopena i ka hui pū me nā hui hydroxyethyl a me nā methyl i hoʻopili ʻia i ka iwi kuamoʻo cellulose.

Hāʻawi ka HEMC i nā waiwai he nui me HPMC, me:

1. Ka Paʻa Wai: He hiki i ka HEMC ke komo a mālama i ka wai, e hoʻohana pono ai i nā mea cementitious e like me ka mortar a me ka tile adhesives e pale ai i ka maloʻo mua 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. Hoʻopaʻa ʻia: kōkua ʻo HEMC i ka hoʻopaʻa ʻana i nā emulsions a me nā hoʻokuʻu, pale i ka hoʻokaʻawale ʻana a me ka mālama ʻana i ka homogeneity huahana.
4. Hoʻokumu kiʻiʻoniʻoni: E like me HPMC, hiki i ka HEMC ke hana i kahi kiʻiʻoniʻoni lahilahi ke hoʻopili ʻia i nā ʻili, hāʻawi i ka pale a hoʻonui i ka pili.
5. Hoʻomaikaʻi ʻia nā waiwai kahe: Hiki iā ia ke hoʻomaikaʻi i nā hiʻohiʻona kahe o nā formulations, hoʻomaʻamaʻa i ka hana a me ka noi.

ʻOi pinepine ʻia ʻo HEMC ma mua o HPMC i kekahi mau noi ma muli o kona haʻahaʻa haʻahaʻa a ʻoi aku ka maikaʻi o ka solubility i ka wai anuanu. Eia nō naʻe, ʻo ke koho ma waena o HEMC a me HPMC e pili ana i nā koi kikoʻī kikoʻī a me nā pae hoʻokō.

I ka hōʻuluʻulu ʻana, ʻo ka HEMC he cellulose ether derivative me kahi ākea o nā noi i nā ʻoihana like ʻole, kahi i waiwai nui ai kona mau waiwai ma ke ʻano he mānoanoa, stabilizer, a me ka mea mālama wai.
