Nīnau pinepine e pili ana iā HPMC

Ua māhele ʻia ka Hydroxypropyl methyl cellulose i nā ʻano like ʻole, a he aha ka ʻokoʻa o kona hoʻohana ʻana?

Hiki ke hoʻokaʻawale ʻia ka HPMC i nā ʻano hikiwawe a me nā ʻano wela wela. Puka koke nā huahana i ka wai anuanu a nalowale i loko o ka wai. I kēia manawa, ʻaʻohe viscosity o ka wai, no ka mea, hoʻopuehu wale ʻia ka HPMC i ka wai a ʻaʻole hoʻoheheʻe maoli. Ma hope o 2 mau minuke (hoʻoulu ʻia), piʻi mālie ka viscosity o ka wai, e hana ana i kahi colloid viscous keʻokeʻo. Hiki i nā huahana hoʻoheheʻe wela ke hoʻopuehu wikiwiki i ka wai wela a nalowale i ka wai wela ke hoʻohui ʻia i ka wai anuanu. Ke hāʻule ka mahana i kahi mahana (e like me ka mahana gel o ka huahana), ʻike mālie ka viscosity a hiki i ka hana ʻana o kahi colloid viscous transparent.

Pehea e hoʻoholo ai i ka maikaʻi o ka hydroxypropyl methyl cellulose maʻalahi a intuitively?

Keokeo. ʻOiai ʻaʻole hiki i ka keʻokeʻo ke hoʻoholo inā he maʻalahi ka HPMC e hoʻohana, a inā hoʻohui ʻia nā mea keʻokeʻo i ke kaʻina hana, e hoʻopilikia ia i kona ʻano, ʻoi aku ka maikaʻi o nā huahana maikaʻi.

ʻO ka maikaʻi: ʻo ka maikaʻi o ka HPMC he 80 mesh a me 100 mesh, a ʻoi aku ka liʻiliʻi o 120 mesh. ʻOi aku ka maikaʻi o ka maikaʻi.

Ka hoʻouna māmā: ma hope o ka hoʻokomo ʻia ʻana o ka HPMC i loko o ka wai e hana i kahi colloid akaka, e nānā i kāna transmittance māmā. ʻOi aku ka nui o ka māmā māmā, ʻoi aku ka maikaʻi. ʻO ia hoʻi, he mau mea hiki ʻole ke hoʻoheheʻe ʻia i loko. ʻOi aku ka maikaʻi o ka hoʻouna ʻana o ka reactor vertical, a ʻoi aku ka ʻino o ka reactor horizontal. Akā naʻe, ʻaʻole ia he manaʻo ʻoi aku ka maikaʻi o ka reactor vertical ma mua o ka reactor horizontal. Nui nā kumu e hoʻoholo ai i ka maikaʻi o ka huahana.

Kaumaha kikoʻī: ʻoi aku ka nui o ka gravity kikoʻī, ʻoi aku ke kaumaha, ʻoi aku ka maikaʻi. ʻO ka maʻamau, no ka mea he kiʻekiʻe ka nui o ka hydroxypropyl i loko. Inā kiʻekiʻe ka ʻike o ka hydroxypropyl, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai.

Kaumaha kikoʻī: ʻoi aku ka nui o ka gravity kikoʻī, ʻoi aku ke kaumaha, ʻoi aku ka maikaʻi. ʻO ka maʻamau, no ka mea he kiʻekiʻe ka nui o ka hydroxypropyl i loko. Inā kiʻekiʻe ka ʻike o ka hydroxypropyl, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai.

He aha nā ʻano hoʻoheheʻe o ka hydroxypropyl methyl cellulose?

Hiki ke hoʻohuiʻia nāʻano hoʻohālike a pau i nā mea ma keʻano maloʻo maloʻo;

I ka wā e pono ai e hoʻohui pono i ka wai wai i ka lumi wela, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ke ʻano dispersion wai anuanu. ʻO ka maʻamau, hiki ke mānoanoa i loko o 10-90 mau minuke ma hope o ka hoʻohui ʻana (hoʻoulu)

Hiki ke hoʻoheheʻeʻia nā hiʻohiʻona maʻamau ma hope o ka huiʻana a me ka hoʻopuehuʻana me ka wai wela, e hoʻohui i ka wai anuanu, e hoʻoulu a hoʻomaha;

Inā hiki mai ka caking a me ka ʻōwili ʻana i ka wā o ka hoʻoheheʻe ʻana, no ka lawa ʻole o ka hui ʻana a i ʻole nā ​​hoʻohālike maʻamau i hoʻohui pono ʻia i ka wai anuanu. I kēia manawa, pono e hoʻoulu kokeʻia.

Inā hana ʻia nā ʻōhū i ka wā e hoʻoheheʻe ʻia ai, hiki ke hoʻoneʻe ʻia ma ke kū ʻana no 2-12 mau hola (ʻo ka manawa kikoʻī e pili ana i ka kūlike o ka hopena), ka hoʻoheheʻe ʻana, kaomi a me nā ʻano hana ʻē aʻe, a i ʻole ka hoʻohui ʻana i ka nui o ka defoamer.

He aha ke kuleana o ka hydroxypropyl methyl cellulose i ka hoʻohana ʻana i ka pauka putty, a inā he kemika?

I loko o ka pauka putty, hoʻokani ʻo ia i ʻekolu mau hana: mānoanoa, paʻa wai a me ke kūkulu ʻana. ʻO ka mānoanoa, hiki i ka cellulose ke mānoanoa, pāʻani i ke ʻano o ka hoʻokuʻu ʻana, mālama i ka hoʻonā ʻaʻahu i luna a i lalo, a pale i ka sagging. Paʻa wai: e hoʻomaloʻo mālie i ka pauka putty, a kōkua i ka lime calcium e hana ma lalo o ka hana o ka wai. Hana: he hopena lubricating ka cellulose, hiki ke hana i ka pauka putty i ka hana maikaʻi. ʻAʻole komo ʻo HPMC i kekahi hopena kemika, akā he hana kōkua wale nō.

He aha ke ʻano o ka mahana gel o ka hydroxypropyl methyl cellulose e pili ana?

ʻO ka mahana gel o HPMC e pili ana i kona ʻano methoxyl. ʻO ka haʻahaʻa o ka methoxyl content, ʻoi aku ka kiʻekiʻe o ka mahana gel.

aia kekahi pilina ma waena o ka hāʻule ʻana o ka pauka putty a me ka hydroxypropyl methyl cellulose?

He mea nui!!! He ʻino ka paʻa wai o ka HPMC, kahi e lilo ai ka pauda.

ʻO ka hoʻohana ʻana i ka hydroxypropyl methyl cellulose i ka pauka putty, he aha ke kumu o nā ʻōhū i loko o ka pauka putty?

Hoʻokani ʻo HPMC i ʻekolu hana i ka pauka putty: mānoanoa, paʻa wai a me ke kūkulu ʻana. ʻO nā kumu o nā ʻōpala penei:

Nui ka wai i hoʻohui ʻia.

Inā ʻoki ʻoe i kahi papa ʻē aʻe ma ka papa lalo ma mua o ka maloʻo ʻana, maʻalahi nō hoʻi ke pohu.
