8. He aha ka hana nui o ka hoʻopili ʻana o HPMC i ka pauka putty, a hana ia ma ke ʻano kemika?

Pane: I loko o ka pauka putty, ʻekolu kuleana o HPMC o ka hoʻomānoanoa ʻana, ka paʻa ʻana o ka wai a me ke kūkulu ʻana. Hoʻomānoanoa: Hiki ke hoʻomānoanoa ʻia ka Cellulose e hoʻokuʻu a mālama i ka hopena like i luna a i lalo, a pale aku i ka sagging. Paʻa wai: e hoʻomaloʻo mālie i ka pauka putty, a kōkua i ka calcium lehu e hana ma lalo o ka hana a ka wai. Kūkulu ʻana: He hopena lubricating ko Cellulose, hiki ke hana i ka pauka putty i kūkulu maikaʻi ʻia. ʻAʻole komo ʻo HPMC i kekahi hopena kemika, akā he hana kōkua wale nō. ʻO ka hoʻohui ʻana i ka wai i ka pauka putty a kau iā ia ma ka paia he hopena kemika, no ka mea, ua hoʻokumu ʻia nā mea hou. Inā ʻoe e wehe i ka pauka putty ma ka paia mai ka paia, e wili iā ia i pauka, a hoʻohana hou, ʻaʻole ia e hana no ka mea ua hoʻokumu ʻia nā mea hou (calcium carbonate). ) pū kekahi. ʻO nā ʻāpana nui o ka pauka kalipuna lehu: kahi hui ʻana o Ca(OH)2, CaO a me kahi liʻiliʻi o CaCO3, CaO+H2O=Ca(OH)2—Ca(OH)2+CO2=CaCO3↓+H2O Aia ka kalipuna lehu i loko o ka wai a me ka ea Ma lalo o ka hana a CO2, hoʻopuka ʻia ka kalipuna kalapona, ʻoiai ʻo HPMC e mālama wale i ka wai, e kōkua ana i ka hopena maikaʻi o ka kalipuna lehu, a ʻaʻole ia e komo i kekahi hopena ponoʻī.

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

Pane: Ma nā huaʻōlelo maʻamau, ʻo ka non-ion kahi mea e ʻole e ionize i 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 ionize 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 ka 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.

10. Aia kekahi pilina ma waena o ka kulu ʻana o ka pauka putty a me HPMC?

Pane: ʻO ka nalowale o ka pauka o ka pauka putty e pili nui ana i ka maikaʻi o ka calcium lehu, a ʻaʻohe pili iki me ka HPMC. ʻO ka haʻahaʻa o ka calcium o ka calcium hina a me ka lakio kūpono ʻole o CaO a me Ca(OH)2 i ka calcium hina e hoʻoulu ai i ka nalowale o ka pauka. Inā pili ia me ka HPMC, a laila inā ʻaʻole maikaʻi ka paʻa ʻana o ka wai o ka HPMC, e hoʻoulu pū ia i ka nalowale o ka pauka.

11. He aha ka pili o ka mahana gel o ka hydroxypropyl methylcellulose?

Pane: Pili ka mahana o ka gel o HPMC i kāna ʻike methoxy, ʻo ka haʻahaʻa o ka ʻike methoxy↓, ʻo ke kiʻekiʻe o ka mahana o ka gel.

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

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

13. He aha ka ʻokoʻa ma waena o ke ʻano wai anuanu koke a me ke ʻano hydroxypropyl methylcellulose hiki ke hoʻoheheʻe ʻia i ka wela i ke kaʻina hana?

Pane: ʻO ke ʻano wai anuanu koke o ka HPMC ua mālama ʻia ma ka ʻili me ka glyoxal, a hoʻopuehu koke ia i ka wai anuanu, akā ʻaʻole ia e hoʻoheheʻe maoli. Hoʻoheheʻe wale ia i ka wā e piʻi ai ka mānoanoa. ʻAʻole mālama ʻia nā ʻano hoʻoheheʻe wela me ka glyoxal. Inā nui ka nui o ka glyoxal, e wikiwiki ka hoʻopuehu ʻana, akā e piʻi mālie ka mānoanoa, a inā liʻiliʻi ka nui, ʻo ka ʻaoʻao ʻē aʻe ka ʻoiaʻiʻo.

14. He aha ke ʻala o ka hydroxypropyl methylcellulose (HPMC)?

Pane: Hoʻohana ka HPMC i hana ʻia e ke ʻano solvent i ka toluene a me ka isopropanol ma ke ʻano he mau solvent. Inā ʻaʻole maikaʻi loa ka holoi ʻana, e koe ana kekahi ʻala.

15. He aha kekahi inoa ʻē aʻe no 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-hydroxypropyl methyl Cellulose ether. Cellulose hydroxypropyl methyl ether Hyprolose.

16. 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 kūpono i 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. Viscosity waena: 75000-100000 Hoʻohana nui ʻia no ka putty. Kumu: paʻa wai maikaʻi. Viscosity kiʻekiʻe: 150000-200000 Hoʻohana nui ʻia no ka polystyrene particle thermal insulation mortar glue powder a me ka vitrified microbead thermal insulation mortar. Kumu: viscosity kiʻekiʻe, ʻaʻole maʻalahi ka mortar e hāʻule, kau, a hoʻomaikaʻi i ke kūkulu ʻana.

17. ʻO ka hoʻopili ʻana o HPMC i ka pauka putty, he aha ke kumu o nā pehu i loko o ka pauka putty?

Pane: I loko o ka pauka putty, hoʻokani ʻo HPMC i ʻekolu kuleana o ka mānoanoa, ka paʻa ʻana o ka wai a me ke kūkulu ʻana. Mai komo i kekahi hopena. Nā kumu no nā pehu: 1. E kau i ka nui o ka wai. 2. ʻAʻole maloʻo ka papa lalo, e ʻeli wale i kahi papa ʻē aʻe ma luna, a maʻalahi hoʻi e huʻa.
