ʻO ka ʻike hydroxypropyl methylcellulose (HPMC)?

1. He aha ke kumu nui o ka hydroxypropyl methyl cellulose (HPMC)?

Hoʻohana nui ʻia ʻo HPMC i nā mea hana, nā uhi, nā resins synthetic, nā ceramics, nā lāʻau lapaʻau, nā meaʻai, nā textiles, nā mahiʻai, nā mea hoʻonaninani, ka paka a me nā ʻoihana ʻē aʻe.

Hiki ke hoʻokaʻawale ʻia ka HPMC i ka papa hana, ka meaʻai a me ka lāʻau lapaʻau e like me kāna kumu.

I kēia manawa, ʻo ka hapa nui o nā huahana kūloko o ke kūkulu hale. I ka papa hana, hoʻohana ʻia ka pauka putty i ka nui nui, ma kahi o 90% e hoʻohana ʻia no ka pauka putty, a hoʻohana ʻia ke koena no ka mortar sima a me ke kāpili.

2. Aia kekahi mau ʻano o ka hydroxypropyl methyl cellulose (HPMC). He aha ka ʻokoʻa ma waena o kā lākou hoʻohana ʻana?

Hiki ke hoʻokaʻawale ʻia ka HPMC i ke ʻano koke a me ke ʻano hoʻoheheʻe wela.

Hoʻopuehu koke ka huahana koke i ka wai anuanu a nalowale i 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 kahi o 2 mau minuke, piʻi mālie ka viscosity o ka wai, e hana ana i kahi colloid viscous transparent.

Hiki ke hoʻohana ʻia ke ʻano wikiwiki, kahi ākea ākea o ka hoʻohana ʻana i ka pauka putty a me ka mortar, a me ka palaki wai a me ka pena.

ʻO ka huahana hoʻoheheʻe wela, i ka wā e hui ai i 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.

3. He aha nā ʻano hoʻoheheʻe o ka hydroxypropyl methyl cellulose (HPMC)?

ʻO ke ʻano hoʻoheheʻe wai wela: No ka hemo ʻole ʻana o HPMC i ka wai wela, hiki ke hoʻopuehu like ʻia ka HPMC i ka wai wela i ka wā mua, a laila hemo koke i ka wā i maʻalili. ʻElua mau ʻano maʻamau i wehewehe ʻia penei:

(1) E kau i ka nui o ka wai wela i makemake ʻia i loko o ka pahu a hoʻomehana iā ia ma kahi o 70 ° C. E hoʻohui mālie i ka hydroxypropyl methylcellulose me ka hoʻoulu lohi, e hoʻomaka i ka HPMC e lana ana ma luna o ka wai, a laila e hana mālie i kahi slurry, a hoʻomaha i ka slurry me ka hoʻoulu ʻana.

(2). 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 hoʻomehana iā 70 ° C. E like me ke ʻano o luna, e hoʻopuehu iā HPMC e hoʻomākaukau i kahi slurry wai wela; a laila e hoʻohui i ke koena o ka wai anuanu i ka slurry wai wela. I loko o ka slurry, hoʻoluʻu i ka hui ma hope o ka hoʻoulu ʻana.

ʻO ke ʻano o ka hui ʻana o ka pauka: E hoʻohui i ka pauka HPMC me ka nui o nā mea pauda ʻē aʻe me kahi hui, a laila hoʻohui i ka wai e hoʻoheheʻe ʻia, a laila hiki ke hoʻoheheʻe ʻia ka HPMC i kēia manawa me ka ʻole o ka clumping, no ka mea, ʻo kēlā me kēia kihi liʻiliʻi, he wahi liʻiliʻi wale nō ka HPMC. E hoʻoheheʻe koke ka pauda i ka wā e hui ai me ka wai.

4. Pehea e hoʻoholo ai i ka maikaʻi o ka hydroxypropyl methylcellulose (HPMC) maʻalahi a intuitively?

(1) Keʻokeʻo: ʻOiai ʻaʻole hiki i ka keʻokeʻo ke hoʻoholo inā he maʻalahi ka HPMC e hoʻohana, a inā hoʻohui ʻia kahi mea hoʻomālamalama i ke kaʻina hana, e hoʻopilikia ia i kona maikaʻi. Eia naʻe, ʻo ka hapa nui o nā huahana maikaʻi he keʻokeʻo maikaʻi.

(2) Fineness: ʻO ka maikaʻi o ka HPMC he 80 mesh a me 100 mesh, 120 mesh ka liʻiliʻi, ʻoi aku ka maikaʻi o ka maikaʻi, ʻoi aku ka maikaʻi.

(3) Ka hoʻouna ʻana: Ma hope o ka hoʻokomo ʻana i ka HPMC i loko o ka wai e hana i kahi colloid akaka, e nānā i kāna transmittance. ʻO ka nui o ka transmittance, ʻoi aku ka maikaʻi, e hōʻike ana he liʻiliʻi nā insolubles i loko.

(4) Pākuʻi: ʻoi aku ka nui o ka ʻāpana, ʻoi aku ke kaumaha o ka maikaʻi. ʻO ka kikoʻī kiʻekiʻe ma muli o ka nui o ka hydroxypropyl content i loko, a ʻoi aku ka kiʻekiʻe o ka hydroxypropyl content, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai.

5. He aha nā hōʻailona ʻenehana nui o ka hydroxypropyl methyl cellulose (HPMC)?

ʻO ka hydroxypropyl content a me ka viscosity, ka hapa nui o ia mau mea e pili ana i kēia mau hōʻailona ʻelua. ʻOi aku ka maikaʻi o ka mālama ʻana i ka wai no ka poʻe me ka hydroxypropyl kiʻekiʻe. ʻOi aku ka maikaʻi o ka viscosity kiʻekiʻe, ka paʻa ʻana o ka wai, pili (ma mua o ka paʻa ʻole), a me ka viscosity kiʻekiʻe, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka mīkini sima.

6. He aha nā mea waiwai nui o ka hydroxypropyl methyl cellulose (HPMC)?

ʻO nā mea waiwai nui o HPMC: ka pulupulu hoʻomaʻemaʻe, methyl chloride, propylene oxide, etc.

7. He aha ka hana nui o ka noi o hydroxypropyl methyl cellulose (HPMC) i ka pauka putty? Aia kekahi hopena kemika?

I ka pauka putty, hoʻokani ʻo HPMC i ʻekolu hana o ka mānoanoa, paʻa wai a me ke kūkulu ʻana.

Mānoanoa: Hiki ke mānoanoa ka cellulose e hoʻokuʻu a mālama i ka hoʻonā ʻaʻahu a i luna a i lalo, a me ka anti-sagging.

Ka mālama ʻana i ka wai: e hoʻomaloʻo mālie i ka pauka putty, a kōkua i ka calcium hina 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, he kuleana kākoʻo wale nō.

8. He aha ke ala o ka hydroxypropyl methyl cellulose (HPMC)?

ʻO ka HPMC i hana ʻia e ke ʻano solvent e hoʻohana i ka toluene a me ka isopropanol e like me ka solvent. Inā ʻaʻole i holoi maikaʻi ʻia, e loaʻa ana kekahi ʻala.

9. Pehea e koho ai i ka hydroxypropyl methylcellulose (HPMC) kūpono no nā kumu like ʻole?

ʻO ka hoʻohana ʻana i ka pauka putty: ʻoi aku ka haʻahaʻa o ke koi, ʻo ka viscosity he 100,000, lawa ia, ʻo ka mea nui ka mālama ʻana i ka wai.

Ka hoʻohana ʻana i ka mortar: koi kiʻekiʻe, viscosity kiʻekiʻe, ʻoi aku ka maikaʻi o 150,000.

Ke noi ʻana i ke kāpili: pono nā huahana koke, me ka viscosity kiʻekiʻe.

10. ʻO ka hoʻohana ʻana i ka hydroxypropyl methyl cellulose (HPMC) i loko o ka pauka putty, he aha ka mea e hoʻohua ai ka pauda putty?

I ka pauka putty, hoʻokani ʻo HPMC i ʻekolu hana o ka mānoanoa, paʻa wai a me ke kūkulu ʻana. Mai komo i kekahi pane.

ʻO nā kumu o nā ʻōpala:

1）. E kau i ka wai nui.

2）. Inā ʻaʻole maloʻo ka papa lalo, e ʻoki wale i kahi papa ʻē aʻe ma luna, e maʻalahi nō hoʻi ka huʻa.

Hoʻomaopopo nui ʻia kā mākou huahana a hilinaʻi ʻia e nā mea kūʻai aku a e ʻoluʻolu i ka hoʻomohala mau ʻana i ka makemake waiwai a me ka pilikanaka no 8 Years Exporter China Construction Grade Cellulose HPMC Hoʻohana ʻia no Drymix Mortar HPMC, Hoʻolako mau ʻia kā mākou mau mea i nā hui he nui a me nā hale hana he nui. I kēia manawa, kūʻai ʻia kā mākou huahana i USA, Italia, Singapore, Malaysia, Russia, Polani, a me ka Middle East.

8 Makahiki Exporter Kina HPMC, Building Material, Hoʻohui mākou i ka hoʻolālā, hana a me ka hoʻokuʻu ʻana me nā limahana akamai ʻoi aku ma mua o 100, ʻōnaehana hoʻomalu maikaʻi a me ka ʻenehana loea. USA, UK, Canada, Europe a me Africa etc.
