He aha ka hydroxypropyl methyl cellulose HPMC?

HPMC hydroxypropyl methyl cellulosemea hana mea hana hale hana mea hoopuka
He aha ka hoʻohana nui o HPMC?
Hiki ke hoʻokaʻawale ʻia ka HPMC i: papa hana, papa meaʻai a me ka lāʻau lapaʻau ma ka hoʻohana ʻana.
Hoʻohana nui ʻia ka HPMC i nā mea kūkulu hale, nā uhi, nā resins synthetic, nā seramika, nā lāʻau lapaʻau, nā meaʻai, nā lole, nā mahiʻai, nā mea hoʻonaninani, ka paka a me nā ʻoihana ʻē aʻe.
I kēia manawa, ʻo ka hapa nui o ka papa hana hale, i ka papa hana, nui ka nui o ka pauka putty, ma kahi o 90% e hoʻohana ʻia e hana i ka pauka putty, hoʻohana ʻia ke koena e hana i ka mortar sima a me ke kāpili.

He aha nā mea maka nui o HPMC?
ʻO nā mea waiwai nui o HPMC: ka pulupulu hoʻomaʻemaʻe, chloromethane, propylene oxide. ʻO nā mea waiwai ʻē aʻe, ʻo ka alkali papa, ka waikawa, toluene, isopropanol a pēlā aku.

- Ua mahele ʻia ʻo HPMC i nā ʻano like ʻole, he aha nā ʻokoʻa o ka hoʻohana ʻana?
Hiki ke hoʻokaʻawale ʻia ka HPMC i ke ʻano hikiwawe a me ka wela.

ʻO nā huahana koke, i loko o ka wai anuanu i hoʻopuehu koke ʻia, nalowale i ka wai, i kēia manawa ʻaʻohe viscosity o ka wai, no ka mea, ua hoʻopuehu wale ʻia ka HPMC i ka wai, ʻaʻohe dissolution 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 ka laula noi ākea, i ka pauka putty a me ka mortar, a me ke kāpili wai a me ka pena, ʻaʻohe kapu.

ʻO nā huahana hiki ke hoʻoheheʻe wela, i ka wai anuanu, hiki ke hoʻopuehu koke i ka wai wela, nalowale i ka wai wela, i ka wā e hāʻule ai ka mahana i kahi mahana, ʻike mālie ka viscosity, a hiki i ka hoʻokumu ʻana o ka colloid viscous. Hiki ke hoʻohana wale ʻia i ka pauka putty a me ka mortar, i loko o ke kolu wai a me ka pena, aia kahi hanana hui, ʻaʻole hiki ke hoʻohana.

He aha nā hōʻailona ʻenehana nui oHPMC?
ʻO ka hydroxypropyl content a me ka viscosity, pili ka hapa nui o nā mea hoʻohana i kēia mau kuhikuhi ʻelua.

He kiʻekiʻe ka ʻike hydroxypropyl, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai.

ʻOi aku ka maikaʻi o ka viscosity, ka paʻa ʻana o ka wai, pili (akā, ʻaʻole paʻa), a ʻoi aku ka maikaʻi o ka viscosity, i loko o ka pahu sima maikaʻi e hoʻohana i kekahi.

ʻEhia ka viscosity kūpono no HPMC?
ʻO ka hana koʻikoʻi o ka HPMC ʻo ka mālama ʻana i ka wai, a ma hope o ka mānoanoa.
ʻO ka pauka Putty ma ke ʻano he 100000 cps hiki. I ka lōʻihi o ka maikaʻi o ka paʻa ʻana o ka wai, haʻahaʻa ka viscosity (70,000-80000), hiki nō hoʻi, ʻoiaʻiʻo, ʻoi aku ka nui o ka viscosity, ʻoi aku ka maikaʻi o ka paʻa wai pili, ke ʻoi aku ka viscosity ma mua o 100,000, ʻoi aku ka viscosity. liʻiliʻi ka hopena i ka mālama ʻana i ka wai.
ʻOi aku ka kiʻekiʻe o ke koi i ka MORTAR, MAKEMAKE MAU 150 THOUSAND i mea maikaʻi e hoʻohana ai.
Ke noi ʻana i ke kāpili: pono nā huahana koke, kiʻekiʻe viscosity.
