He nui nā mea hoʻohana e hoʻolohe i ka pilikia o ka mahana gel o hydroxypropyl methylcellulose. I kēia mau lā, ʻike ʻia ka hydroxypropyl methylcellulose e like me ka viscosity, akā no kekahi mau ʻenehana kūikawā a me nā ʻoihana kūikawā, ʻike wale ʻia ka viscosity o ka huahana. ʻAʻole lawa, hōʻike pōkole kēia i ka mahana gel o ka hydroxypropyl methylcellulose.
ʻO ka maʻiʻo o ka methyl acid e pili pono ana i ka ester-forming degree o cellulose ester, a ua hoʻoponopono ʻia ka ʻike o ka methyl acid i mea e hoʻomalu ai i ka hoʻokumu ʻana, ka mahana hopena a me ka manawa pane. I ka manawa like, pili ka pae o ka ether solution i ka ʻike o ka hydroxyethyl a i ʻole hydroxyapatite. No laila, e emi ka pulu nā cellulose ethers i nā mahana kiʻekiʻe maʻamau o ka gel. Pono e ʻike ʻia kēia kaʻina hana, no laila ma kahi o nā haʻahaʻa haʻahaʻa o nā methoxides, e piʻi iki nā cellulose ethers i ke kumukūʻai.
Hoʻoholo ʻia ka mahana o ka gel me ka methoxide a me ka hydroxyproazepam me ka hydroxyproxin. ʻEkolu wale nō pūʻulu hiki ke hoʻololi i ka cellulose. E ʻimi i ka mahana kūpono, mālama i ka haʻahaʻa, a hoʻoholo i ke ʻano o ka pulp. ʻO ka mahana o ka gel ka mea koʻikoʻi no ka hoʻohana ʻana i ka cellulose ether. Ke hoʻokuʻu ʻia ka ether cellulose mai ka wai. ʻO ka mahana o ka pulp ma ka mākeke ka mea nui e hoʻokō i nā pono o ka hopena i ke kaiapuni (koe wale nā kūlana kūikawā). Manaʻo ʻia i ka wā e hoʻohana ai i ka hopena, ʻaʻole pono e uku kūikawā i nā hōʻailona hana i ka wā e hoʻohana ai i ka gel. ʻOiaʻiʻo, pono e noʻonoʻo ka mea hana o cellulose ether i kēia hōʻailona.
