Hydroxypropyl methylcellulose, 28-30% methoxyl, 7-12% hydroxypropyl

ʻO nā kikoʻī "28-30% methoxyl" a me "7-12% hydroxypropyl" e pili ana i ke kiʻekiʻe o ka hoʻololi ʻana i loko.Hydroxypropyl Methylcellulose(HPMC). Hōʻike kēia mau waiwai i ka nui o ka polymer cellulose kumu i hoʻololi ʻia me nā hui methoxyl a me hydroxypropyl.

1. 28-30% Methoxyl:
   • Hōʻike kēia, ma ka awelika, ua hoʻololi ʻia ka 28-30% o nā pūʻulu hydroxyl kumu ma ka mole cellulose me nā pūʻulu methoxyl. Hoʻokomo ʻia nā hui Methoxyl (-OCH3) e hoʻonui i ka hydrophobicity o ka polymer.
2. 7-12% Hydroxypropyl:
   • Hōʻike kēia, ma ka awelika, ua hoʻololi ʻia ka 7-12% o nā pūʻulu hydroxyl kumu ma ka mole cellulose me nā hui hydroxypropyl. Hoʻokomo ʻia nā pūʻulu Hydroxypropyl (-OCH2CHOHCH3) e hoʻomaikaʻi i ka hoʻoheheʻe wai a hoʻololi i nā waiwai kino a me nā kemika o ka polymer.

Hoʻopili ka pae o ka hoʻololi ʻana i nā waiwai o HPMC a me kāna hana i nā noi like ʻole. ʻo kahi laʻana:

• ʻO ka maʻiʻo methoxyl kiʻekiʻe ka mea maʻamau e hoʻonui i ka hydrophobicity o ka polymer, e pili ana i kona hoʻoheheʻe wai a me nā waiwai ʻē aʻe.
• Hiki i ka mea hydroxypropyl kiʻekiʻe ke hoʻonui i ka hoʻoheheʻe wai a me nā waiwai hana kiʻiʻoniʻoni o HPMC.

He mea koʻikoʻi kēia mau kikoʻī i ka hana ʻana i ka HPMC e hoʻokō i nā koi kikoʻī i nā ʻoihana like ʻole. No ka laʻana, ma ka ʻoihana lāʻau lapaʻau, hiki ke koho ʻia ka papa HPMC me nā pae kikoʻī o ka hoʻololi ʻana i nā kiʻi hoʻokuʻu lāʻau i loko o nā papa papa. I ka ʻoihana kūkulu, hiki iā ia ke hoʻopili i ka paʻa ʻana o ka wai a me nā waiwai adhesion o nā huahana sima.

Hana nā mea hana i nā māka like ʻole o ka HPMC me nā pae like ʻole o ka hoʻololi ʻana e hoʻokō i nā pono like ʻole o nā noi like ʻole. I ka hoʻohana ʻana i ka HPMC i loko o ka hoʻopili ʻana, he mea nui i nā mea hoʻopuka e noʻonoʻo i ka pae kikoʻī o ka HPMC e kūlike me nā waiwai i makemake ʻia a me nā hiʻohiʻona hana no ka noi i manaʻo ʻia.
