ʻO HydroxyPropsl MilymerLulose (HPMC) he polymer ʻO nā mea nui nui i hoʻohanaʻia e hana i ka hpmc he cellulose a me ka prostlene ox
1. Cellouse:ʻO ke kumu o HPMC
1.1 Kaʻikeʻana o ka cellouse
ʻO ka cellulouse kahi mea hoʻokūkū paʻakikī e paʻakikī ana ka mea nui o ka papa hana nui o nā wahi kanu lāʻau. Aia nō ia i nā kaulahao o nā mika o nā molena glucose ʻO ka nui o nā hui hydroxyl i nā cellulose e hana ai i kahi mea e hoʻomaka ai no ka synthesis no nā drivatives o nā cellulose likeʻole
1.2 Cellulose Procurement
Hiki ke kiʻiʻiaʻo Cellouse mai nā mea kanu likeʻole, e like me nā lāʻau lāʻau, nā mea kanu lāʻau, a iʻole nā mea kanu'ē aʻe. ʻO ka lāʻau lāʻau, he kumu maʻamau ia no kona nui, kūʻai-kumukūʻai, a me ke kūpaʻa. ʻO ka hoʻoiliʻana o ka celilouse maʻamau e pili ana i ka wāwahiʻana i nā mea kanu kanu ma waena o nāʻano o nā kaʻina hana a me nā kaʻina hana.
1.,3 maʻemaʻe a me nā hiʻohiʻona
ʻO ka maikaʻi a me ka maʻemaʻe o ka cellulouse he koʻikoʻi e hoʻoholo ai i nāʻano o ka huahana HPMC hope loa. Mālamaʻia nā lāʻau lapaʻau kiʻekiʻe e like me ka hpmc i hanaʻia me nā waiwai kūlike e like me ka viscosity
2.ʻO PPYLENCNE OXIDE: Kuhi i ka hoʻolahaʻana o ka hydrosybopypopyp
2.1 Hoʻomaopopo iā Psplenene Oxide
ʻO PospleneʻO Prospene He epoxide, he mea e loaʻa ai i kahi oxygen agygen atom i hoʻopaʻaʻia i nā carbon carbon carbon i hoʻopiliʻia. ʻO Prosplene oxdeneʻo ka mea nui e kī ai i ka synthesis no ka synthesis of hydroxyproopsl cellulouse,ʻo ia kahi waena no ka hpmc.
2.2
Hoʻokomoʻia ke kaʻina hana hydroxyproxy. Hoʻohana pinepineʻia kēia hopena ma ke alo o kahi catalyst. ʻO nā hui hydroxyprooppyl e hāʻawi aku i nā mea kūpono a me nā waiwai'ē aʻe e makemake ai i nā waiwai'ē aʻe i ka cellulouse, e alakaʻi ana i ka hoʻokumuʻana o ka hydroxyprockl cellulous.
3.
3.1 Ke kaʻina hana mitylation
Ma hope o ka hydroxyprocklation,ʻo ka pae aʻe e hiki mai ana i ka synthes o hpmc. Ua pili ke kaʻina hana i ka hoʻomakaʻana o nā hui Momell ma ke kua o Celoulose. ʻO ka mlorde maʻamauʻo Mityl Chloride he mea maʻamau maʻamau no kēia hopena. ʻO ke kiʻekiʻe o ka huiʻana e pili ana i nā waiwai o ka huahana HPMC hope loa, me konaʻano Valcosity a me keʻano Gel.
3.2 ka pae o ke koi
ʻO ke kiʻekiʻe o keʻano (DS) he mea nui ke kī nui no ka heluʻana i ka helu maʻamau o nā cossittinut Ua mālama ponoʻia ke kaʻina hana hana e hoʻokō ai i ka hana makemake o nā huahana HPMC.
4.ʻO ka hoʻomaʻemaʻe a me ka mana kūpono
4.1 ka weheʻana o nā huahana
Hiki i ka synthesis o ka hpmc e hopena i ka hoʻokumuʻana o nā huahana e like me nā mea e like me nā mea kūʻai aku a iʻoleʻole. Hoʻohanaʻia nā hana hoʻomaʻemaʻe me ka holoiʻana a me ka filtration e wehe i kēia mau mea haumia a hoʻonui i ka hoʻomaʻemaʻe o ka huahana hope.
4.2ʻO nā hana hoʻomalu maikaʻi
Hoʻopiliʻia nā hana paʻa paʻa paʻa i ka hana hana e hōʻoia ai e hōʻoia i keʻano a me keʻano o ka HPMC. ʻO nāʻenehana hoʻohālikelike e like me ka Spectroscopy,ʻo Chromatography a me Rheology i hoʻohanaʻia e loiloi i nāʻano molletate

5.1ʻO nā waiwai pilikino
He keʻokeʻoʻo HPMC i ke keʻokeʻo a me ke keʻokeʻo a me nā mea nui e pili ana i nā waiwai filcking filcking filcking. ʻO ia ka hygroscopic a me ka maʻalahi e hana i kahi gel transparent i ka wā i hoʻopauʻia i ka wai. Ua hilinaʻiʻia ka hopena o ka HPMC ma ke kiʻekiʻe o ka hoʻololi a ua hoʻopilikiaʻia e nā mea e like me ka mahana a me PH.
5.2ʻO keʻano Chempical
ʻO keʻano o keʻano o ka HPMC i kahi hope o ke poʻo cellulose me hydroxyproopsl a me ka modyl subsityents. ʻO ka laulā o kēia mau mea i loaʻa, e noʻonoʻo ana i ke kiʻekiʻe o ka squarenall, e hoʻoholo i keʻano o ka HPMC
5.3 Viscosity a me Gheological Properties
Loaʻaʻo HPMC i nā helu likeʻole me nāʻano viscosityʻokoʻa'ē aʻe. ʻO ka mea nānā aku o nā hopena HPMC he mea nui i nā noi e like me nā mea kūʻai aku e like me nā lāʻau lapaʻau, kahi e hoʻopilikia ai i kahi hana o nā mea kanu a me nā pasteration.
5.4ʻO nā kiʻi kiʻi kiʻi a me nā waiwai nui
Ua hoʻohana nuiʻiaʻo HPMC ma keʻano he kiʻiʻoniʻoni ma mua o nā hale kūʻai lāʻau lapaʻau a me he mea lā he nui o nāʻano likeʻole. ʻO kāna mau kiʻi kiʻi kiʻi kiʻi i ka waiwai nui i ka hoʻomohalaʻana i nā'ōnaehana o ka lāʻau lapaʻau i hoʻopaʻaʻia,ʻoiaiʻo kāna mau mea nui e hoʻonui ai i nā huahana a me ka kūpaʻa o nā huahana nui.
6.ʻO ka noiʻana o ka hydroxyproopsl
6.1ʻO kaʻoihana lāʻau lapaʻau
Ma kaʻoihana lāʻau lapaʻau, ua hoʻohanaʻiaʻo HPMC e hana i nāʻano o nā mea e like me nā papa hana a me nā kālapa. Hoʻohana pinepineʻiaʻo ia ma keʻano he binder, disintegrant a me nā kiʻiʻoniʻoni kiʻiʻoniʻoni. ʻO nā waiwai i hoʻokuʻuʻia i ka HPMC e hoʻomaʻamaʻa i kāna noi i nā hana i hoʻokuʻuʻia.
6.2 kūkulu'āina
I loko o ka hana kūkulu kūkulu, ua hoʻohanaʻiaʻo HPMC ma keʻano he wai e noho ana i ka wai, ua paʻa a me ka adhesize i nā huahana cement. Hoʻonui ia i ka hana o ka paina o ka paina, e pale i ka hanaʻana i nā noi pili, a hoʻomaikaʻi i ka hana holoʻokoʻa o ka Hale Aupuni.
6.3ʻO ka hana meaʻai meaʻai
Hoʻohanaʻiaʻo HPMC i kaʻoihana meaʻai e like me ka shaickener, stabilizer a me nā emulsifier. ʻO kona hiki ke hana i nā gels i nā mea haʻahaʻa haʻahaʻa e kūpono ai i nāʻano noi, me nāʻano mea kanu, nā lole a me nā lole.
6.4 mau cosmetics a me nā huahana mālama pilikino
I nā Cosmetics a me nā huahana mālama pilikino,ʻo HPMC i loaʻa i loko o kahiʻano o nāʻano o nā creamdiations me nā creams, nā shampoos. Kōkua ia i ka hoʻomaikaʻiʻana i kaʻatikala, ka hoʻomau a me ka hana holoʻokoʻa o kēia mau huahana.
6.5 mauʻoihana'ē aʻe
Ua hoʻolōʻihiʻiaʻo HPMC i nāʻoihana'ē aʻe, e komo pū me nā mea kākau, nā kiʻi a me nā kiʻi e hoʻohanaʻia e like me keʻano o ka rheology
7 .a hopena
ʻO ka hydroxyproopylfopylfopylclolose kahi polymer buckmer me nā noi he nui. Hoʻohanaʻo synthesis i ka cellulose a me ka propslene o ka oxde e like me nā mea nui, a ke hoʻololiʻia ka cellulose ma o ka hydroxyprodolation a me ka huiʻana o ka cellulose. Hiki i ka kāohiʻana o kēia mau mea waiwai a me nā kūlana kūpono e hiki ai ke hana hou i nā hpmc me nā waiwai maʻamau e hoʻokō i nā pono hana kūikawā. No laila, ua pāʻaniʻo HPMC i kahi koʻikoʻi koʻikoʻi i ka hoʻomaikaʻiʻana i ka hana a me ka hana o nā huahana ma nāʻoihana. ʻO kaʻimi mauʻana o nā noi hou a me ka hoʻomaikaʻiʻana i nā kaʻina hana e kōkua ai i ka HPMC e hoʻomau i kahi hana koʻikoʻi ma ka mākeke Global.
