Hydroxypropyl Methylcellulose HPMC E3, E5, E6, E15, E50, E4M

ʻO Hydroxypropyl Methylcellulose (HPMC) he cellulose ether i loaʻa nā māka like ʻole, i hōʻike ʻia e nā leka a me nā helu. Hōʻike kēia mau māka i nā kikoʻī like ʻole, me ka hoʻololi ʻana i ke kaumaha molekala, ʻike hydroxypropyl, a me ka viscosity. Eia ka haʻihaʻi ʻana o nā māka HPMC āu i ʻōlelo ai:

1. HPMC E3:
   • E pili ana kēia papa i ka HPMC me kahi viscosity kiko'ī 2.4-3.6CPS. Hōʻike ka helu 3 i ka viscosity o kahi solution aqueous 2%, a ʻo nā helu kiʻekiʻe e hōʻike i ka viscosity kiʻekiʻe.
2. HPMC E5:
   • E like me E3, hōʻike ka HPMC E5 i kahi papa viscosity ʻokoʻa. Hōʻike ka helu 5 i ka viscosity kokoke 4.0-6.0 CPS o kahi hopena wai 2%.
3. HPMC E6:
   • ʻO HPMC E6 kahi papa ʻē aʻe me kahi ʻano viscosity ʻokoʻa. Hōʻike ka helu 6 i ka viscosity 4.8-7.2 CPS o kahi hopena 2%.
4. HPMC E15:
   • Hōʻike paha ʻo HPMC E15 i kahi māka viscosity kiʻekiʻe ke hoʻohālikelike ʻia me E3, E5, a i ʻole E6. Hōʻike ka helu 15 i ka viscosity 12.0-18.0CPS o kahi hoʻonā wai wai 2%, e hōʻike ana i kahi kūlike ʻoi aku ka mānoanoa.
5. HPMC E50:
   • Hōʻike ka HPMC E50 i kahi māka viscosity kiʻekiʻe, me ka helu 50 e hōʻike ana i ka viscosity 40.0-60.0 CPS o kahi hopena 2%. He ʻoi aku ka nui o ka viscosity o kēia papa ma mua o E3, E5, E6, a i ʻole E15.
6. HPMC E4m:
   • ʻO ka "m" ma E4m ka mea maʻamau i ka viscosity waena 3200-4800CPS. Hōʻike ka HPMC E4m i kahi papa me ka pae viscosity haʻahaʻa. He kūpono paha ia no nā noi e koi ana i ke kaulike ma waena o ka wai a me ka mānoanoa.

Ke koho ʻana i kahi māka HPMC no kahi noi kikoʻī, e noʻonoʻo ʻia ka viscosity i makemake ʻia, solubility, a me nā ʻano hana ʻē aʻe. Hoʻohana pinepine ʻia ka HPMC i nā ʻoihana e like me ke kūkulu ʻana, nā lāʻau lapaʻau, nā mea hoʻonaninani, a me nā meaʻai.

Ma ka meaʻai, hoʻohana pinepine ʻia ka HPMC ma ke ʻano he mea hoʻohui i nā huahana waiu ʻole e hoʻomaikaʻi i nā waiwai e like me ka mālama ʻana i ka wai, ka hana, a me ka hoʻopili. I nā lāʻau lapaʻau a me nā mea hoʻonaninani, hoʻohana ʻia ʻo HPMC no kāna mau mea hana kiʻiʻoniʻoni a me ka mānoanoa.

He mea koʻikoʻi ke kūkākūkā me ka mea hana a mea hoʻolako paha no ka loaʻa ʻana o ka ʻike kikoʻī kikoʻī, me nā kikoʻī a me nā noi i manaʻo ʻia no kēlā me kēia papa HPMC. Hāʻawi maʻamau nā mea hana i nā pepa ʻikepili ʻenehana a me nā palapala huahana e alakaʻi i nā mea hoʻohana i ke koho ʻana i ka pae kūpono loa no kā lākou pono kikoʻī.
