——Azịza: Ọdịnaya Hydroxypropyl na viscosity, ọtụtụ ndị ọrụ na-eche banyere ihe ngosi abụọ a. Ka ọdịnaya hydroxypropyl dị elu, ka mma na-ejigide mmiri. Nnukwu viscosity, njide mmiri, dịtụ (kama nke zuru oke) ka mma, na viscosity dị elu, nke ka mma na-eji ciment mortar.

8. Kedu ihe bụ isi akụrụngwa nke hydroxypropyl methylcellulose (HPMC)?

—— A: Isi akụrụngwa nke hydroxypropyl methylcellulose (HPMC): owu a nụchara anụcha, methyl chloride, propylene oxide, akụrụngwa ndị ọzọ gụnyere flake alkali, acid, toluene, isopropanol, wdg.

9. Gịnị bụ isi ọrụ nke HPMC na ngwa nke putty ntụ ntụ, na e nwere ihe ọ bụla kemistri?

——Azịza: HPMC nwere atọ ọrụ nke ndim, idowe mmiri na ewu na putty ntụ ntụ. Ọkpụkpụ: Enwere ike ịgbatị cellulose ka ọ kwụsịtụ, dobe ihe ngwọta ahụ n'otu ma na-agbanwe agbanwe, ma guzogide ịda mbà n'obi. Njide mmiri: Mee ka ntụ ntụ putty kpoo nwayọọ nwayọọ, ma nyere aka mmeghachi omume nke calcium ash n'okpuru ọrụ mmiri.

Ịgbakwunye mmiri na ntụ ntụ na-etinye ya na mgbidi bụ mmeghachi omume kemịkal. N'ihi nhazi nke ihe ọhụrụ, wepụ ntụ ntụ na-edozi ahụ na mgbidi ahụ, gwerie ya ka ọ bụrụ ntụ ntụ ma jiri ya ọzọ. Ọ gaghị arụ ọrụ, n'ihi na e mepụtala ihe ọhụrụ (calcium carbonate). ) elu. Isi ihe dị na ntụ ntụ calcium ash bụ: ngwakọta nke Ca (OH) 2, CaO na obere ego CaCO3, CaO + H2O = Ca(OH) 2 -Ca (OH) 2+ CO2 = CaCO3↓+ H2O Ash calcium N'ime mmiri na ikuku N'okpuru ọrụ nke CO2, calcium carbonate na-emepụta, ebe HPMC na-ejigide mmiri naanị ma na-enyere aka mmeghachi omume ka mma nke calcium ash, ma ọ dịghị etinye aka na mmeghachi omume ọ bụla n'onwe ya.

10. HPMC bụ onye na-abụghị ionic cellulose ether, yabụ kedu ihe na-abụghị ionic?

- Azịza: N'okwu ndị nkịtị, ndị na-abụghị ions bụ ihe ndị na-adịghị ionize na mmiri. Ionization na-ezo aka na usoro nke a na-ekewa electrolyte n'ime ion ebubo na-ebugharị n'efu na ihe mgbaze (dị ka mmiri, mmanya). Dịka ọmụmaatụ, sodium chloride (NaCl), nnu a na-eri kwa ụbọchị, na-agbaze n'ime mmiri na ionizes iji mepụta sodium ion (Na+) na-emegharị n'enweghị ihe ọ bụla na ion chloride (Cl) bụ nke na-adịghị mma. Ya bụ, mgbe a na-etinye HPMC na mmiri, ọ naghị ekewa n'ime ion ebubo, kama ọ dị n'ụdị molecules.
