ʻO ke kaʻina hana e hana ai e hana i ka cellouse ma waena o nā hopena o ka hopena ma hope o ka nānāʻana me ka matery checks ʻO ka maʻamau,ʻo ke kiʻekiʻe o ke kohoʻana he 1.6 ~ 2.0 No ia mea no ka neetic cellouse eter.
Hoʻopiliʻiaʻo Mitylcellse i ka wai anuanu, a he mea paʻakikī ke hoʻopau i ka wai wela. ʻO kona hopena kūpono loa he paʻa loa i ka laulā o ka PH = 3 ~ 12.
He kūpono maikaʻi me ka starch, guar gum, etc. a me nā mea he nui. I ka wā i hōʻea ai keʻano o keʻano i ka mahana o keʻano, ua kūʻia kahi kūlana.
ʻO ka mālamaʻana o ka wai o Mithylcellose e pili ana i kona nui o kona nui,ʻo Viscosity, ka pākaukau a me ka uku uku.
Generation, inā nui ka nui o ka huina, heʻuʻuku ka maikaʻi, he nui ka nalo, he nui ka helehelena kai. I waena o lākou,ʻo ka nui o ka hoʻohuiʻana ka hopena nui nui loa ma ka helu mālama wai,ʻaʻole kūpono ka kiʻekiʻe o ka viscosity i ka pae o ka pae mālama uku. Ke hilinaʻi nui nei ka helu dissolution i ke kiʻekiʻe o ka hoʻololiʻana i ka hoʻololiʻana i nā'āpana cellouse a me nā'āpana maikaʻi.
Ma waena o nā mea i luna aʻe i luna aʻe,ʻo Mityl Cellulouse a me ka hydroxyproopyl milllulse e loaʻa nā kumukūʻai o ka wai.
Carboxourcetcethlfallolose (cmc)
ʻO CarboxyMethyll Cellulouse,ʻikeʻiaʻo iaʻo Sodium CarboxyMyl Cellilse, iʻike pinepineʻia kahiʻano o ka celluluse, clc. Nā mea kanu ponoʻole.
Ua hoʻohana nuiʻia ia i kaʻoihana hana, nā meaʻai meaʻai a me ka meaʻai meaʻai a me kaʻaila o ka palaoa, a me ka nui i hoʻohanaʻia ma nā cosmetics wale nō no 1%.
Hanaʻiaʻo IonicLause eter nā mea koko kūlohelohe (Cotton, etc.) ma hope o kaʻoihanaʻo Alikali me ka'āpana o ka maʻi'āina.
ʻO ke kiʻekiʻe o ka hoʻololiʻanaʻo 0.4 ~ 1,4
Loaʻa iā CMC ke paʻa i ka hiki ke kūpono, a me kona hopena momona he kūpono maikaʻi ke kānalua, akāʻaʻohe waiwai o nā platection maʻamau maʻamau.
I ka wā e kū ai ka cmc, e kū maoli ana ka depolymerization. Hoʻomaka ka viscosity e ala i ka wā o ka hoʻohemoʻana, e hele i ka nui, a laila hāʻule i kahi pāpū. ʻO keʻano hopena o ka mea hōʻike e pili ana i ka depolymeization.
ʻO ke kiʻekiʻe o ka depolymeization e pili kokoke ana i ka nui o ka nui o ka mea i hoʻopaʻaʻia (ka wai) i keʻano. Ma kahi'ōnaehana maikaʻiʻole, e like me ka niho niho e loaʻa ana i ka glycerin a me ka wai,ʻaʻole e hoʻokaʻawale ka cmc.
I ka hihia o kahi o ka wai i hāʻawiʻia,ʻoi aku ka maʻalahi o ka cmc hydrophilic i kohoʻia e depolyshized ma mua o ka cmc haʻahaʻa.
HydroxySethylcellolose (hec)
Hanaʻiaʻo Hec e ka mālamaʻana i kaʻili i hoʻopaʻaʻia me Alkali, a laila hoʻi hou me Etelene Matene. ʻO ke kiʻekiʻe o ka hoʻololiʻana he 1.5 ~ ~ 2.0. He hydrophinicity ikaika a maʻalahi hoʻi e hoʻopili i ka'ōpū.
Hoʻopiliʻiaʻo Hydroxyethyl Cellulouse ma ka wai anuanu, akā he mea paʻakikī ke hoʻokaʻawale i ka wai wela. ʻO kāna hoʻonā e paʻa ana ma ke kiʻekiʻe kiʻekiʻe me keʻanoʻole.
He mea paʻa ia i nā wahi maʻamau a me nā waihona. Hiki i Alkalis ke hoʻopau i kona neʻeʻana a hoʻonui iki i kona viscosity. ʻO ka mea hoʻowahāwahā i loko o ka wai iʻoi aku ka maikaʻi ma mua o kēlā o ka cellulose cellulouse a me hydroxyproopyl milllulse.
Hydroxyprooppropyl mithyl cellie (hpmc)
ʻO keʻano molecular o HPMC:
\ [C6h7oo2 (OH) 3-MNN (OCH3) M, Och2ch (Och2ch (Och38 *
ʻO ka hydroxxyprooparllose kaʻano celesylrellse kahiʻano celetouse ka mea colnalsel browulose he mea like ka hopena a me kaʻaiʻana.
ʻO ia kahi cellulose i huiʻia i huiʻia e ka eter i hanaʻia ma hope o ka paleʻana i ka cotton ma hope o ka alkalization, e hoʻohana ana i nāʻano o ka eteryl. ʻO ke kiʻekiʻe o ka hoʻololiʻana he 1.2 ~ 2.0.
ʻOkoʻa kona mau waiwai ma muli o nāʻano likeʻole o nāʻano methoyl a me ka hydroxyproblel.
ʻO ka hydroxyprooppopyll methylcrelllulose e maʻalahi maʻalahi i ka wai anuanu, akā e hālāwai me ka paʻakikī i ka hoʻopauʻana i ka wai wela. Akāʻo konaʻano hoʻonaʻauao nui ma ka wai wela,ʻoi aku ka kiʻekiʻe ma mua o ka makika o Mathyl Cellowse. ʻO ka pale kūlohelohe i ka wai anuanu nui e hoʻolōʻihiʻia ai nā wai me ka huiʻana o ka mollulse.
ʻO ka nānāʻana o ka viscosity o hydroxyproopproplose e pili ana i kona kino noho kūlohelohe, aʻo kaʻoi aku ka nui. Pākuʻi pū kahiʻano i kona mau viscomeness, e hoʻonui anaʻo ia mahana. Eia nō naʻe,ʻo ia kahi mākaʻikaʻi kiʻekiʻe he haʻahaʻa haʻahaʻa haʻahaʻa ma mua o ka cellulose cellulouse. Ke kūpaʻa nei kona hopena i ka wā i mālamaʻia ai ma ka mahana o ka lumi.
ʻO ka mālamaʻana o ka wai o ka hydroxyprooparloppopuka, e pili ana i kona nui o ka nui, etc.
ʻO ka hydroxxyprooppopplayl mathylcelllose ke paʻaʻia i ka ACID lāuaʻo Alkali, a me kona hopena kūpono loa i kūʻoleʻia ma ka laulā o PH = 2 ~ 12. He make light a me Litik i ka hopena o ka nui o ka hana, akā e hoʻokōʻo Alkili i kona kīnāʻana a me ka hoʻonuiʻana i kānaʻano mākaʻikaʻi.
Kūponoʻiaʻo hydroxyprooparluroll
Hiki ke hoʻohuiʻiaʻo Hydroxypopyl mathylClolose me ka wai hoʻohuihui wai-sollable i loko o nā hui polommer E like me ka polyvinyl agan, starch ether
Uaʻoi aku ka maikaʻi o ka hydroxyproopyl
