E pili ana i ka pilikia o ka mahana gel o ka hydroxypropyl methylcellulose HPMC, he nui nā mea hoʻohana e hoʻolohe ʻole i ka pilikia o ka mahana gel o hydroxypropyl methylcellulose.I kēia mau lā, ʻokoʻa ka hydroxypropyl methylcellulose e like me ka viscosity, akā no kekahi mau kaiapuni kūikawā a me nā ʻoihana kūikawā, ʻaʻole lawa ka hōʻike wale ʻana i ka viscosity o ka huahana.Hōʻike pōkole kēia i ka mahana gel o ka hydroxypropyl methylcellulose.
ʻO ka nui o ka pūʻulu methoxyl e pili pono ana i ke kiʻekiʻe o ka cellulose sourization, a hiki ke hoʻoponopono ʻia ka ʻike o ka pūʻulu methoxyl ma ke kāohi ʻana i ke ʻano, ka mahana hopena a me ka manawa pane.I ka manawa like, pili ka pae o ka inactivation i ke kiʻekiʻe o ka hoʻololi ʻana o ka hydroxyethyl a i ʻole hydroxypropyl.No laila, ʻo ka mālama ʻana i ka wai o cellulose ether me ka wela gel kiʻekiʻe e ʻilihune.Pono e ʻimi ʻia kēia kaʻina hana, no laila ʻaʻole ia he haʻahaʻa ke kumu kūʻai o ka cellulose ether inā haʻahaʻa ka ʻike methoxy, ʻoi aku ka kiʻekiʻe o ke kumukūʻai.
Hoʻoholo ʻia ka mahana o ka gel e nā hui methoxyl, a ʻo ka paʻa ʻana o ka wai e hoʻoholo ʻia e nā hui hydroxypropoxyl.ʻEkolu wale nō mau pūʻulu hoʻololi ma cellulose.E ʻimi i kāu wela hoʻohana kūpono, paʻa wai kūpono, a laila e hoʻoholo i ke kumu hoʻohālike o kēia cellulose.
He wahi koʻikoʻi ka mahana gel no ka hoʻohana ʻana i ka cellulose ether.Ke ʻoi aku ka mahana o ka ambient i ka mahana gel, e hoʻokaʻawale ʻia ka cellulose ether mai ka wai a nalowale kona paʻa wai.ʻO ka mahana gel o cellulose ether ma ka mākeke hiki ke hoʻokō pono i nā pono o ka hoʻohana ʻana i ka mortar (koe wale no nā wahi kūikawā).I ka hoʻohana ʻana i ka mortar, ʻaʻohe pono e nānā kūikawā i ka index hana o ka mahana gel.
