Pehea e koho ai i ka hydroxypropyl methylcellulose kūpono no ka putty pā o loko a me waho

Pehea e koho ai i ka HPMC pono

1. E like me ke kŘkohu: E like me nā ʻano like ʻole o nā putties like ʻole, ʻokoʻa nā hiʻohiʻona viscosity o hydroxypropyl methylcellulose a me methylcellulose. Hoʻohana ʻia lākou mai 40,000 a 100,000. I ka manawa like, ʻaʻole hiki i ka fiber Vegetarian ether ke hoʻololi i ke kuleana o nā mea hoʻopili ʻē aʻe, ʻo ka hoʻohui ʻana i ka cellulose ether ʻaʻole ia he manaʻo e hiki ke hoʻemi ʻia nā mea hana o nā mea hoʻopili ʻē aʻe.

2. Pono ʻoe i ka wai anuanu dispersible cellulose ether: ʻO ka cellulose ether (me ka hydroxypropyl methylcellulose a me ka methylcellulose) he surfactant me ka viscosity kiʻekiʻe ma hope o ka dissolution. ʻO ia ke kumu o kēia ʻano, inā hoʻohui ʻia ka cellulose ether maʻamau i ka wai, ua maʻalahi ke hana ʻana i ka pōleʻa, a ua hoʻoheheʻe ʻia ka waho o ka pōleʻa i loko o ka wai mānoanoa loa, a ua uhi ʻia ka loko, a paʻakikī. no ke komo ʻana o ka wai i loko, ka hopena o ka hoʻoheheʻe ʻana. . ʻAʻole e like me kēia ka cellulose ether i mālama ʻia i ka ʻili (e hiki ke hoʻopaneʻe i ka dissolution), a hiki ke hoʻopuehu maikaʻi ʻia i loko o ka wai anuanu (hoʻolohi i ka dissolution, a hoʻoheheʻe mālie ma hope o ka hoʻopuehu ʻana). He koho maikaʻi e hoʻomaopopo i nā ʻokoʻa ma luna.

1. No ka mea maloʻo i hui ʻia i loko a me waho o ka pā pā, no ka mea, ua hoʻopuehu maikaʻi ʻia ka cellulose ether i loko o ka mea i ka wā o ka hui maloʻo, ʻaʻohe agglomeration. No laila, pono e hoʻohana i ka ʻano maʻamau (ʻano hoʻopuehu wai ʻole), no ka mea, ʻoi aku ka wikiwiki o ka dissolution rate o nā ʻano maʻamau ma mua o ke ʻano o ka hoʻopuehu wai anuanu, e hoʻopōkole ana i ka manawa kali mai ka hui ʻana i ka slurry i ke kūkulu ʻana.

2. No ka hoʻomākaukauʻana i ka putty e hoʻoheheʻe pono i ka cellulose ether (me ka hydroxypropyl methylcellulose a me ka methylcellulose) i loko o ka wai a hui pū me nā mea'ē aʻe, ua'ōleloʻia e hoʻohana i ka wai anuanu keʻano cellulose ether. Hiki ke hoʻopuehu maikaʻi ʻia ka cellulose ether ma luna o ka wai anuanu a hoʻoheheʻe ʻia (hiki ke hoʻopanee i ka hoʻoheheʻe ʻana)
