ʻIke paha ʻoe i ka hydroxypropyl methylcellulose?

Hoʻohana nui ʻia ka Hydroxypropyl methylcellulose i ka ʻoihana kūkulu. I kēia lā, e hoʻolauna wau i ke ʻano o ka dissolution o hydroxypropyl methylcellulose a pehea e hoʻoponopono ai i ka maikaʻi o ka hydroxypropyl methylcellulose.

ʻO ke ʻano o ka hoʻopau ʻana i ka hydroxypropyl methylcellulose:

Hiki ke hoʻohuiʻia nā hiʻohiʻona a pau i ka mea ma ka hui maloʻo;

I ka wā e pono e hoʻohui pololei i ka maʻamau aqueous solution, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ke ʻano dispersion wai anuanu, a hiki ke mānoanoa i loko o 10-90 mau minuke ma hope o ka hoʻohui ʻana;

Ma hope o ka hoʻoulu ʻana a me ka hoʻopuehu ʻana me ka wai wela no ke ʻano maʻamau, e hoʻohui i ka wai anuanu a hoʻoulu e hoʻoheheʻe;

Inā loaʻa ka agglomeration a me ka uhi ʻana i ka wā o ka hoʻoheheʻe ʻana, ma muli o ka lawa ʻole o ka hoʻoulu ʻana a i ʻole ka hoʻohui pololei ʻana o ka wai anuanu i nā profiles maʻamau. I keia manawa, pono e hoonaue koke ia;

Inā hoʻokumu ʻia nā ʻōpala i ka wā o ka hoʻoheheʻe ʻana, hiki ke waiho ʻia e kū no nā hola 2-12 (hoʻoholo ʻia e like me ke kūlike o ka hopena) a i ʻole e hoʻoneʻe ʻia e ka haʻalele ʻana, pressurization, etc.

Pehea e hoʻoholo ai i ka maikaʻi o ka hydroxypropyl methylcellulose maʻalahi a intuitively

Keʻokeʻo: E like me ka keʻokeʻo, ʻaʻole hiki ke hoʻoholo inā hiki ke hoʻohana maʻamau ka HPMC, a inā hoʻohui ʻia nā mea keʻokeʻo i ke kaʻina hana, e hoʻopilikia pū ia i kona ʻano. Eia naʻe, ʻoi aku ka maikaʻi o nā huahana me ka keʻokeʻo maikaʻi.

Maikaʻi: ʻO ka HPMC maʻamau he 80 mesh, 100 mesh, 120 mesh, ʻoi aku ka maikaʻi o ka ʻoi aku ka maikaʻi.

Ka lawe ʻana: e hoʻokomo i ka HPMC i loko o ka wai e hana i kahi colloid akaka, a e nānā i kāna transmittance. ʻOi aku ka nui o ka hoʻouna ʻana, ʻoi aku ka liʻiliʻi o nā mea hiki ʻole i ka wai. ʻO ka maʻamau, ʻoi aku ka maikaʻi o ka transmittance i nā reactors vertical a me nā reactors horizontal. ʻOi aku ka maikaʻi o ka reactor vertical, akā ʻaʻole hiki ke wehewehe i ka maikaʻi o ka huahana i hana ʻia e ka reactor vertical ma mua o ka reactor horizontal.

Kaumaha kikoʻī: ʻO ka mea maʻamau, no ka nui o ka hydroxypropyl content, maikaʻi ka hopena paʻa wai.
