ʻO ka ʻokoʻa ma waena o ka hypromellose koke a me ka hypromellose hiki ke hoʻonā wela

I kēia manawa, hoʻokaʻawale ʻia ka hydroxypropyl methylcellulose i ka mākeke kūloko i ke ʻano hoʻoheheʻe wela (i kapa ʻia hoʻi ke ʻano hoʻoheheʻe lohi) a me ke ʻano hoʻoheheʻe koke, a ʻo ke ʻano hoʻoheheʻe wela ʻo ia ka mea maʻamau a me ka ʻano o ka cellulose.

ʻAʻole mālama ʻia ka HPMC me ka glyoxal hydroxypropyl methylcellulose HPMC.Inā nui ka nui o ka glyoxal, e wikiwiki ka hoʻopuehu ʻana, akā e piʻi mālie ka viscosity, a inā liʻiliʻi ka nui, ʻo ia ka ʻaoʻao.ʻO ka Hydroxypropyl methylcellulose HPMC e hui pū i ka wā e hālāwai ai me ka wai anuanu (akā, e hoʻoheheʻe mālie kēia kūlana, akā lōʻihi ka manawa.), akā e hoʻopuehu koke ia i ka wai i ka wai wela a nalowale loa i ka wai, a piʻi ka viscosity. lohi i ka wā e hāʻule mālie ai ka mahana a hiki i ka lilo ʻana i wai ʻeleʻele alohilohi.Ua like kona clumping hanana me ka hemo ana o ka sodium carboxymethyl cellulose kiʻekiʻe-viscosity.Ke hoʻoheheʻe ʻia ka pauda cellulose ma waho o ka wai, lilo ia i viscous, a laila wili i ka cellulose i loko ʻaʻole i hoʻopā i ka wai, akā e hoʻoheheʻe ʻia kēia kūlana, akā lōʻihi ka manawa.

Hoʻohana ʻia ka HPMC hydroxypropyl methylcellulose ʻano koke me ka glyoxal.Puka koke ia i ka wai anuanu, ʻaʻole naʻe e hemo maoli.Loaʻa ka manawa e piʻi aʻe ai kona viscosity, no ka mea, hoʻolaha wale ia i ka wai i ka wā mua, ʻaʻole ia he mea koʻikoʻi maoli.No ka hoʻopau ʻana i luna, hiki i ka viscosity ke kiʻekiʻe loa ma kahi o kanahā mau minuke.Ke piʻi aʻe ka viscosity, e akaka a ʻike ʻia ka hoʻonā wai, ʻo ia ka dissolution maoli.Hoʻohana ʻia ka HPMC hydroxypropyl methylcellulose HPMC i kahi ʻoihana kūikawā a ʻaʻole e hui pū ʻia me ka pauka maloʻo, a i ʻole i ka wā e pono ai e hoʻoheheʻe ʻia a ʻaʻole hiki ke hoʻohana ʻia ka wai wela ma muli o nā kūlana lako a me nā kumu ʻē aʻe, ʻano hypromellose Cellulose-based solution. i ka pilikia pilikia.
