ʻO ka hana hanaʻo HPMC a me ke kahe

ʻO Hydroxyprooparplayl Mileylcellse (HPMC) he Polymer ākea ākea i hoʻohana pinepineʻia i loko o nā lāʻau lapaʻau, ka hana a me nāʻoihana'ē aʻe. ʻO kona mau waiwai kūʻokoʻa e lilo i waiwai nui i nā noi mai nā'ōnaehana o ka lāʻau lapaʻau e hāʻawi i nāʻoihana i nā huahana meaʻai. Ka hoʻomaopopoʻana i ka hana hana a me ke kahe o ka hpmc he mea nui no ka hōʻoiaʻana i ka maikaʻi o ka huahana a me ka loaʻa.

1.raw koho koho:
A. ʻO Cellouse kumu: HPMC i loaʻa mai nā cellulouse, maʻamau i hanaʻia mai ka lāʻau lāʻau a iʻole nā ​​litrover coot.
b. Pono ka hoʻomaʻemaʻeʻana i nā pono maʻemaʻe Hiki i nā haumia ke hoʻopilikia i ka hana a me nā waiwai o ka huahana hope loa.
c hoowela. ʻO ke kiʻekiʻe o ka hoʻololiʻana (DS): E hoʻoholo ka DS o HPMC i kāna mau palena kūpono a me nā waiwai gelution. Koho i nā mea hana i nā cellulose me nā pae ds kūpono e pili ana i ka noi i makemakeʻia.

2.E hopena:
A. ʻO ka Athetififification:ʻO Prosplene oxy a me Mityl Chloride maʻamau maʻamau i hoʻohana pinepineʻia i nā mea iterofication ma HPMC.
b. Nā hanana hoʻololi: Ke hele nei nā kaʻina Hoomaliiliol lalo o ka mahana o ke aniani, kaomi, a me nā kumu PH e hoʻokō ai i nā DS.
c hoowela. ʻO Catalysts: Alkali Catalysts e like me ka sodium hydroxide a iʻole ka payroxide hydroxide a iʻole ka hanaʻana i ka hopena o ka eterroxide.
d. E nānā ana

3.Purification a me ka holoiʻana:
A. Ka weheʻana i nā haumia
b. ʻO ka holoiʻana i nā hana hana
c hoowela. Hoʻopili a me ka hoʻomaʻemaʻeʻana: E hana ana nāʻenehana filtration e hoʻokaʻawale iā HPMC mai ka holoiʻana i nā huahana hope loa e loaʻa ai nā huahana hope loa.

4.Particticle ka mana nui:
A. ʻO ke aniani a me ka Milling:ʻO HPMC mau'āpana i kauʻia e hoʻopiliʻia e hoʻopili a me nā hana hoʻohālike e kāohi i ka māhele'āpana.
b. ʻO Sieving: Ke hana nei nāʻenehana Sievy e hōʻoia i ka hoʻokaʻawaleʻana i keʻano o ka hoʻokaʻawaleʻana i ka hoʻohanaʻana i ka nui o ka hoʻokaʻawaleʻana a wehe i nā'āpana overversized.
c hoowela. ʻO ka papa kuhikuhi'āpana: E hoʻokaʻawale i nā hana loiloi nui e like me ka laser e like me ka laser a he microscopy a iʻole microscopy e hōʻike i nā huapalapala hpmc

5.
A. Hoʻohuiʻia ka hoʻohuiʻana: E kiʻiʻiaʻo HPMC me nā mea hoihoi a me nā hoʻohui e hoʻopili ai i kāna mau waiwai no nā noi kūikawā.
b. ʻO Homogenization:ʻO nā hana hoʻohui e hōʻoia ai i ka hoʻokaʻawaleʻana o HPMC i loko o HPMC i loko o nāʻano hana e loaʻa ai nāʻano hana makemake.
c hoowela. ʻO ka manaʻo hoʻohālikelike

6.
A. ʻO ka ho'āʻoʻana: nāʻenehana like likeʻole e like me ka pīhoihoi infrared, chromatography, aʻo ka rheology i hanaʻia no ka hpmc.
b. DS manaʻo: Ua hana pinepineʻia nā DS o HPMC e hōʻoia i ka hōʻoiaʻana a me ka hoʻomaikaʻiʻana i nā kiko'ī.
c hoowela. Ka nānāʻana i ka hōʻikeʻana: nā kūlana kūwaho kūwaho, nā mea kīwī kaumaha, a me ka hoʻomaʻemaʻe microbial i nānāʻia e hōʻoiaʻiʻo ai i ka palekana palekana.

7.papila a me ka mālama:
A. ʻO nā mea hana SPECAGING: HPMC maʻamau i hoʻopaʻaʻia i nā mea paʻa e pale i nā mea e pale aku ai i ka degradation a mālama i ka maikaʻi o ka huahana.
b. Mālamaʻia nā kūlana: e mālamaʻiaʻo HPMC i kahi maloʻo maloʻo, maikaʻi ma kahi o ka lā kūpono e pale ai i ka piliʻana a me ka lepo.
c hoowela. ʻO ke olaʻo Shelf

ʻO ka hana hana hana o HPMC e pili ana i kahiʻano o nā hana i weheweheʻia, mai nā koho o ka mea kūʻai aku i ka helu huahana hou. Pono kēlā me kēia papa hana i ka mālama ponoʻana a nānā pono e hōʻoia i ka maikaʻi o ka huahana Ma ka hoʻomaopopoʻana i ka hana hana a me ke kahe o HPMC, hiki i nā mea hana ke koho i ka hana hana a me nā pono o nāʻoihana'ē aʻe.
