Mahana gel HPMC

ʻAʻole nui ka poʻe hoʻohana e hoʻolohe pinepine i ka pilikia o ka mahana o ka gel hydroxypropyl methyl cellulose HPMC. I kēia mau lā, ʻike nui ʻia ka hydroxypropyl methyl cellulose HPMC e ka viscosity, akā no kekahi mau wahi kūikawā a me nā ʻoihana kūikawā, ʻo ka viscosity wale nō o ka huahana e hōʻike ʻia ana. ʻAʻole lawa, eia ka mea e hōʻike pōkole ana i ka mahana o ka gel hydroxypropyl methylcellulose HPMC.

Pili pono ka ʻike o ka hui methoxy i ke kekelē o ka etherification o ka cellulose ether. Hiki ke hoʻololi ʻia ka ʻike o ka hui methoxy ma o ka kaohi ʻana i ke ʻano, ka mahana o ka hopena a me ka manawa hopena. I ka manawa like, pili ka ʻike o ka etherification i ke kekelē o ka hoʻololi ʻana o ka hydroxyethyl a i ʻole hydroxypropyl. No laila, ʻoi aku ka ʻino o ka paʻa ʻana o ka wai o ka cellulose ether me ka mahana gel kiʻekiʻe. Pono e ʻimi ʻia kēia kaʻina hana, no laila ʻaʻole no ka mea he haʻahaʻa ka ʻike o ka methoxy, haʻahaʻa ke kumukūʻai o ka cellulose ether, ma ke ʻano ʻē, e ʻoi aku ke kiʻekiʻe o ke kumukūʻai.

ʻO ka nui o ka hydroxypropyl methyl cellulose HPMC hydroxypropyl o QUALICELL he 25%. ʻO ka mahana o ka gel kahi kiko koʻikoʻi no ka hoʻopili ʻana o ka cellulose ether. Ke ʻoi aku ka mahana o ka ambient ma mua o ka mahana o ka gel, e puka ka cellulose ether mai loko mai o ka wai a nalowale kona paʻa wai. ʻO ka mahana o ka cellulose ether gel o Qualicell he 65 degere, hiki ke hoʻokō i nā pono o ke kaiapuni hoʻohana mortar a me ka putty (koe wale nō nā kaiapuni kūikawā). Inā kūʻai ʻoe iā QualiCell HPMC, e ʻoluʻolu e hoʻomaopopo mua inā he mau koi kūikawā kāu.
