1. He nui nā ʻano o ka HPMC hydroxypropyl methylcellulose, a he aha ka ʻokoʻa ma waena o kā lākou hoʻohana ʻana?
Pane: Hiki ke hoʻokaʻawale ʻia ʻo Hydroxypropyl methylcellulose HPMC i ke ʻano koke a me ke ʻano hoʻoheheʻe wela. Puka koke nā huahana ʻano ʻano koke i ka wai anuanu a nalowale i loko o ka wai. I kēia manawa, ʻaʻohe viscosity o ka wai, no ka mea, ua hoʻopuehu wale ʻia ka HPMC i ka wai, ʻaʻohe dissolve maoli. Ma hope o 2 mau minuke, piʻi mālie ka viscosity o ka wai, e hana ana i kahi colloid viscous transparent. ʻO nā huahana hoʻoheheʻe wela, ke hālāwai me ka wai anuanu, hiki ke hoʻopuehu koke i ka wai wela a nalowale i ka wai wela. Ke hāʻule ka mahana i kahi mahana, ʻike mālie ka viscosity a hiki i ka hoʻokumu ʻana o kahi colloid viscous transparent. Hiki ke hoʻohana wale ʻia ke ʻano hoʻoheheʻe wela i ka pauka putty a me ka mortar. I loko o ke kolu wai a me ka pena, e kū mai ke ʻano clumping a ʻaʻole hiki ke hoʻohana. Loaʻa i ka ʻano koke ka laulā o nā noi. Hiki ke hoʻohana ʻia i loko o ka pauka putty a me ka mortar, a me ka wai wai a me ka pena, me ka ʻole o nā contraindications.
2. He aha ke kumu nui o ka hydroxypropyl methylcellulose (HPMC)?
A: Hoʻohana nui ʻia ka HPMC i nā mea kūkulu hale, nā uhi, nā resins synthetic, ceramics, lāʻau lapaʻau, meaʻai, textile, mahiʻai, mea hoʻonaninani, paka a me nā ʻoihana ʻē aʻe. Hiki ke hoʻokaʻawale ʻia ka HPMC i: papa hana, papa meaʻai a me ka lāʻau lapaʻau e like me ke kumu. I kēia manawa, ʻo ka hapa nui o nā huahana home ka pae kūkulu. I ka papa hana, he nui loa ka nui o ka pauka putty, ma kahi o 90% e hoʻohana ʻia no ka pauka putty, a hoʻohana ʻia ke koena no ka mortar sima a me ke kāpili.
3. He aha nā ʻano hoʻoheheʻe o ka hydroxypropyl methylcellulose HPMC?
Pane: ʻO ke ʻano hoʻoheheʻe wai wela: No ka mea ʻaʻole i hoʻoheheʻe ʻia ka HPMC i ka wai wela, hiki ke hoʻopuehu like ʻia ka HPMC i ka wai wela i ka wā mua, a laila e hoʻoheheʻe koke ʻia ke hoʻomaloʻo. ʻElua mau ʻano maʻamau i wehewehe ʻia penei:
1), e hoʻohui i 1/3 a i ʻole 2/3 o ka nui o ka wai i makemake ʻia i loko o ka pahu, a wela iā 70 ° C, e like me ke ʻano o 1), hoʻopuehu HPMC, hoʻomākaukau i ka slurry wai wela; a laila hoʻohui i ke koena o ka wai anuanu i ka wai wela I loko o ka slurry, ua maʻalili ka hui ʻana ma hope o ka hoʻoulu ʻana.
ʻO ke ʻano o ka hui ʻana o ka pauda: E hui pū i ka pauka HPMC me ka nui o nā mea pauda ʻē aʻe, e hui pono me ka mea hui pū, a laila e hoʻohui i ka wai e hoʻoheheʻe ʻia, a laila hiki ke hoʻoheheʻe ʻia ka HPMC i kēia manawa me ka ʻole o ka hui ʻana, no ka mea he ʻuʻuku wale ka HPMC i kēlā me kēia. kihi liʻiliʻi liʻiliʻi. E hoʻoheheʻe koke ʻia ka pauka i ka pili ʻana me ka wai. ——Ke hoʻohana ʻia nei kēia ʻano e nā mea hana i ka pauka putty a me ka motar. [Hoʻohana ʻia ka Hydroxypropyl methylcellulose (HPMC) ma ke ʻano he mānoanoa a me ka mea hoʻopaʻa wai i loko o ka mortar pauka putty.
2), e hoʻokomo i ka nui o ka wai wela i loko o ka pahu, a wela iā ia ma kahi o 70 ℃. Hoʻohui mālie ʻia ka hydroxypropyl methylcellulose me ka hoʻoulu lohi ʻana, i ka mua ua lana ka HPMC ma luna o ka ʻili o ka wai, a laila hana mālie i kahi slurry, i hoʻoluʻu ʻia me ka hoʻoulu ʻana.
4. Pehea e hoʻoholo ai i ka maikaʻi o ka hydroxypropyl methylcellulose (HPMC) maʻalahi a intuitively?
Pane: (1) Kaumaha kikoʻī: ʻoi aku ka nui o ka ʻumekaumaha kikoʻī, ʻoi aku ka ʻoi aku ka maikaʻi. nui, no ka mea
(2) Keʻokeʻo: ʻOiai ʻaʻole ʻike ka keʻokeʻo i ka maʻalahi o ka HPMC e hoʻohana, a inā hoʻohui ʻia kahi mea keʻokeʻo i ke kaʻina hana, e pili ana ia i kona maikaʻi. Eia naʻe, ʻo ka hapa nui o nā huahana maikaʻi he keʻokeʻo maikaʻi.
(3) Maikaʻi: ʻO ka maikaʻi o ka HPMC he 80 mesh a me 100 mesh, a ʻoi aku ka liʻiliʻi o 120 mesh. ʻO ka hapa nui o ka HPMC i hana ʻia ma Hebei he 80 mesh. ʻO ka ʻoi aku ka maikaʻi o ka maikaʻi, ʻoi aku ka maikaʻi ma ka laulā.
(4) Hoʻouna: E hoʻokomo i ka hydroxypropyl methylcellulose (HPMC) i loko o ka wai e hana i kahi colloid akaka, a nānā i kāna transmittance. ʻO ke kiʻekiʻe o ka transmittance, ʻoi aku ka maikaʻi, e hōʻike ana he liʻiliʻi nā mea hiki ke hoʻoheheʻe ʻia i loko. ʻOi aku ka maikaʻi o ka permeability o nā reactors vertical, a ʻoi aku ka maikaʻi o nā reactors horizontal, akā ʻaʻole hiki ke ʻōlelo ʻia ʻoi aku ka maikaʻi o nā reactors vertical ma mua o nā reactors horizontal, a he nui nā kumu e hoʻoholo ai i ka maikaʻi o nā huahana. He kiʻekiʻe ka ʻike hydroxypropyl i loko, a he kiʻekiʻe ka nui o ka hydroxypropyl, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai.
5. He aha nā hōʻailona ʻenehana nui o ka hydroxypropyl methylcellulose (HPMC)?
Pane: Hydroxypropyl content and viscosity, ka hapanui o nā mea hoʻohana e mālama i kēia mau hōʻailona ʻelua. ʻOi aku ka nui o ka hydroxypropyl content, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai. Viscous, paʻa wai, ʻano (ma kahi o
6. He aha ka viscosity kūpono o ka hydroxypropyl methylcellulose (HPMC)?
Pane: ʻO ka pauka Putty ma ke ʻano he 100,000 yuan, a ʻoi aku ka koi o ka mortar, a maʻalahi ke hoʻohana ma 150,000 yuan. Eia kekahi, ʻo ka hana koʻikoʻi o ka HPMC ʻo ka mālama ʻana i ka wai, a ukali ʻia e ka mānoanoa. I ka pauka putty, ʻoiai ka maikaʻi o ka paʻa ʻana o ka wai a haʻahaʻa ka viscosity (70,000-80,000), hiki nō hoʻi. ʻOiaʻiʻo, inā ʻoi aku ka kiʻekiʻe o ka viscosity, ʻoi aku ka maikaʻi o ka paʻa wai pili. Ke ʻoi aku ka viscosity ma mua o 100,000, ʻaʻole nui ka hopena o ka viscosity i ka mālama ʻana i ka wai. ʻOiaʻiʻo) ʻoi aku ka maikaʻi, a he kiʻekiʻe ka viscosity, a ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka mīkini sima.
7. He aha nā mea maka nui o ka hydroxypropyl methylcellulose (HPMC)?
Pane: ʻO nā mea waiwai nui o ka hydroxypropyl methylcellulose (HPMC): ka pulupulu hoʻomaʻemaʻe, methyl chloride, propylene oxide, nā mea waiwai ʻē aʻe e pili ana i ka flake alkali, acid, toluene, isopropanol, etc.
