HPMC gel wela pilikia

E pili ana i ka pilikia o ka mahana gel oHydroxypropyl Methyl Cellulose HPMC, He nui nā mea hoʻohana e hoʻolohe ʻole i ka pilikia o ka mahana gel o Hydroxypropyl Methyl Cellulose. I kēia mau lā, ʻokoʻa ʻia ka Hydroxypropyl Methyl Cellulose e like me kona viscosity, akā no kekahi mau kaiapuni kūikawā a me nā ʻoihana kūikawā, ʻaʻole lawa ia e hōʻike wale i ka viscosity o ka huahana. Hōʻike pōkole kēia i ka mahana gel o Hydroxypropyl Methyl Cellulose.

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 hui Methoxyl ma ka hoʻomalu 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 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, akā 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 Hydroxypropoxy. 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.

ʻO ka mahana gel he wahi koʻikoʻi no ka hoʻohana ʻana ocellulose etera. 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). Manaʻo wau ʻaʻole pono e uku kūikawā i ka helu hana o ka mahana gel i ka wā e noi ai i ka mortar. ʻOiaʻiʻo, pono e noʻonoʻo nā mea hana o cellulose ether.
