Hiddroxyprooppopalse, mili othlcellse, 28-30% Methoxyl, 7-12% hydroxyproplerl

ʻO nā kiko'ī "28-30% Methoxyl" a "7-12% hydroxyproopsl" e kuhikuhi i ke kiʻekiʻe o keʻanoHydrexxypopypoprowlse(Hpmc). Hōʻike kēia mau waiwai i ka nui o keʻano o ka polymer i hoʻololiʻia me nā hui chemyl a me nā hui hydroxyl.

1. 28-30% Methoxyl:
   • Hōʻike kēia i kēlā, ma ka awelika, 28-30% o nā hui hydroxyl mua ma ka cellulose molecle i hoʻololiʻia me nā hui metala. Ua hoʻokomoʻia nā hui methoxyl (-och3) e hoʻonui i ka hydrohobicity o ka polymer.
2. 7-12% hydroxyprooppopppppsl:
   • Ua hōʻailona kēia i kēlā, ma ka awelika, 7-12% o nā hui hydroxyl mua ma keʻano he cellouse molecule i hoʻopiliʻia me nā hui hydroxyproopyl. Nā hui Hydroxyproopsl

ʻO ke kiʻekiʻe o ka hoʻololiʻana i nā waiwai o HPMC a me kāna hana i nā noi likeʻole. ʻo kahi laʻana:

• Hoʻonuiʻia kahiʻikepili kiʻekiʻe kiʻekiʻe loa i ka hydrohobicity o ka polymer, e pili ana i kona mau wai wai a me nā waiwai'ē aʻe.
• Hiki i kahiʻikepili hydroxypopyl i hiki ke hoʻonui i ka palena wai wai a me nā kiʻi kiʻi kiʻi kiʻi o HPMC.

ʻO kēia mau kiko'ī he mea nui ma ka tailoring hpmc e hoʻokō i nā koi kiko'ī i nāʻoihana likeʻole. No ka laʻana, ma kaʻoihana lāʻau lapaʻau, ke koho o ka helu HPMC me nā helu kiko'ī e pili ana i nā hana e hiki ai i nā papa hana o ka lāʻau. I kaʻoihana kūkuluʻana, hiki iā ia ke hoʻokō i ka pūnāwai wai a me nā waiwai o nā huahana cement.

Hana nā mea hana i nā mea hana likeʻole o HPMC me nā kiʻekiʻe'ē aʻe o ka hoʻololiʻana e hoʻokō ai i nā pono o nā noi likeʻole. Ke hoʻohana nei i ka HPMC i nā hana, he mea nui ia no nā mea hana e noʻonoʻo ai i ka helu o ka HPMC a me nāʻano hana i makemakeʻia.
