Ke kamaʻilio nei e pili ana i ka Hydroxypropyl Methyl Cellulose (HPMC)

1. He aha ka inoa kapakapa o ka hydroxypropyl methylcellulose?

——Pane: Hydroxypropyl Methyl Cellulose, Pelekania: Hydroxypropyl Methyl Cellulose Pōkole: HPMC a i ʻole MHPC Alias: Hypromellose; Cellulose Hydroxypropyl Methyl Ether; Hypromellose, Cellulose, 2-hydroxypropylmethyl Cellulose ether. Cellulose hydroxypropyl methyl ether Hyprolose.

2. He aha ka hoʻohana nui ʻana o ka hydroxypropyl methylcellulose (HPMC)?

——Pane: Hoʻohana nui ʻia ka HPMC i nā mea hana hale, nā uhi, nā resins synthetic, nā keramika, nā lāʻau lapaʻau, ka meaʻai, nā lole, ka mahiʻai, nā mea hoʻonani, ka paka a me nā ʻoihana ʻē aʻe. Hiki ke hoʻokaʻawale ʻia ka HPMC i ke ʻano hana hale, ke ʻano meaʻai a me ka ʻano lāʻau lapaʻau e like me ke kumu. I kēia manawa, ʻo ka hapa nui o nā huahana kūloko he ʻano hana hale. I ke ʻano hana hale, hoʻohana nui ʻia ka pauka putty, ma kahi o 90% e hoʻohana ʻia no ka pauka putty, a hoʻohana ʻia ke koena no ka sima sima a me ke kāpili.

3. Aia kekahi mau ʻano hydroxypropyl methylcellulose (HPMC), a he aha nā ʻokoʻa o kā lākou hoʻohana ʻana?

——Pane: Hiki ke hoʻokaʻawale ʻia ka HPMC i ke ʻano koke a me ke ʻano hoʻoheheʻe wela. Hoʻopuehu koke nā huahana ʻano koke i ka wai anuanu a nalowale i loko o ka wai. I kēia manawa, ʻaʻohe mānoanoa o ka wai no ka mea ua hoʻopuehu wale ʻia ka HPMC i ka wai me ka ʻole o ka hoʻoheheʻe maoli ʻana. Ma kahi o 2 mau minuke, piʻi mālie ka mānoanoa o ka wai, e hana ana i kahi colloid viscous maopopo. ʻO nā huahana hoʻoheheʻe wela, i ka wā e hui ai 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, e ʻike mālie ʻia ka mānoanoa a hiki i ka hana ʻana i kahi colloid viscous maopopo. Hiki ke hoʻohana wale ʻia ke ʻano hoʻoheheʻe wela i ka pauka putty a me ka mortar. I loko o ka glue wai a me ka pena, e loaʻa kahi hanana hui a ʻaʻole hiki ke hoʻohana ʻia. Loaʻa i ke ʻano koke kahi ākea o nā noi. Hiki ke hoʻohana ʻia i loko o ka pauka putty a me ka mortar, a me ka glue wai a me ka pena, me ka ʻole o nā contraindications.

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

——Pane::Hoʻopili ʻana i ka pauka putty: He haʻahaʻa iki nā koi, a ʻo ka mānoanoa he 100,000, ua lawa ia. ʻO ka mea nui ka mālama pono ʻana i ka wai. Hoʻopili ʻana i ka mortar: nā koi kiʻekiʻe, ka mānoanoa kiʻekiʻe, ʻoi aku ka maikaʻi o 150,000. Hoʻopili ʻana i ke kāpili: pono nā huahana koke me ka mānoanoa kiʻekiʻe.

5. He aha nā mea e pono e hoʻolohe ʻia i ka hoʻopili maoli ʻana o ka pilina ma waena o ka mānoanoa a me ka mahana o HPMC?

——Pane: ʻO ke ʻano mānoanoa o HPMC he kūlike ʻole ia me ka mahana, ʻo ia hoʻi, piʻi ka mānoanoa i ka emi ʻana o ka mahana. ʻO ke ʻano mānoanoa o kahi huahana a mākou e ʻōlelo pinepine ai e pili ana i ka hopena hoʻāʻo o kāna hopena wai 2% ma ka mahana o 20 degere Celsius.

I nā hana kūpono, pono e hoʻomaopopo ʻia ma nā wahi me nā ʻokoʻa nui o ka mahana ma waena o ke kauwela a me ka hoʻoilo, ua ʻōlelo ʻia e hoʻohana i kahi viscosity haʻahaʻa i ka hoʻoilo, kahi mea e ʻoi aku ka maikaʻi no ke kūkulu ʻana. A i ʻole, i ka wā e haʻahaʻa ai ka mahana, e piʻi aʻe ka viscosity o ka cellulose, a e kaumaha ka manaʻo lima i ka wā e ʻoki ai.

Ka mānoanoa waena: 75000-100000 i hoʻohana nui ʻia no ka putty

Ke kumu: mālama maikaʻi i ka wai

Ka mānoanoa kiʻekiʻe: 150000-200000 Hoʻohana nui ʻia no ka polystyrene particle thermal insulation mortar rubber powder a me ka vitrified microbead thermal insulation mortar.

Kumu: Kiʻekiʻe ka mānoanoa, ʻaʻole maʻalahi ka hāʻule ʻana o ka sima, ʻaʻole palupalu, a ua hoʻomaikaʻi ʻia ke kūkulu ʻana.

6. ʻO HPMC kahi ʻetera cellulose non-ionic, no laila he aha ka non-ionic?

——Pane: Ma ka ʻōlelo maʻamau, ʻo nā non-ion he mau mea i hoʻokaʻawale ʻole ʻia i loko o ka wai. ʻO ka ionization ke kaʻina hana e hoʻokaʻawale ʻia ai kahi electrolyte i loko o nā ion i hoʻopiʻi ʻia e hiki ke neʻe manuahi i loko o kahi mea hoʻoheheʻe kikoʻī (e like me ka wai, ka waiʻona). No ka laʻana, ʻo ka sodium chloride (NaCl), ka paʻakai a mākou e ʻai ai i kēlā me kēia lā, hoʻoheheʻe ʻia i loko o ka wai a hoʻokaʻawale ʻia e hana i nā ion sodium neʻe manuahi (Na+) i hoʻopiʻi maikaʻi ʻia a me nā ion chloride (Cl) i hoʻopiʻi maikaʻi ʻole ʻia. ʻO ia hoʻi, ke kau ʻia ʻo HPMC i loko o ka wai, ʻaʻole ia e hoʻokaʻawale i loko o nā ion i hoʻopiʻi ʻia, akā aia ma ke ʻano o nā molekala.
