Ọrụ nke hydroxypropyl methylcellulose na putty
Site na ndina, njigide mmiri na iwu nke ọrụ atọ.
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. Mwube: Cellulose nwere mmetụta mmanu mmanu, nke nwere ike ime ka uzuzu putty nwee ezigbo ọrụ. Hydroxypropyl methylcellulose anaghị esonye na mmeghachi omume kemịkal ọ bụla ma na-arụ naanị ọrụ inyeaka. A na-etinye ntụ ntụ Putty na mmiri iji mee mgbidi ahụ, nke bụ mmeghachi omume kemịkalụ, n'ihi na e nwere nhazi nke calcium carbonate ọhụrụ. Isi ihe dị na ntụ ntụ calcium ash bụ: ngwakọta nke calcium hydroxide Ca (OH) 2, calcium oxide CaO na obere ego nke calcium carbonate CaCO3. Calcium Ash na-emepụta calcium carbonate n'okpuru ọrụ nke CO2 na mmiri na ikuku, ebe hydroxypropyl methyl Cellulose na-ejigide mmiri ma na-enyere aka mmeghachi omume ka mma nke calcium ash, nke n'onwe ya adịghị etinye aka na mmeghachi omume ọ bụla.
Anyị na-ebu ụzọ nyochaa ihe kpatara nsị ntụ ntụ nke putty site na akụrụngwa nke putty: ntụ ntụ calcium, hydroxypropyl methylcellulose, nnukwu calcium ntụ ntụ, mmiri ash calcium ntụ ntụ.
1. Na mmepụta n'ezie, iji mee ka ire ere dị ngwa ngwa, a na-abawanye okpomọkụ calcination na 1000-1100 Celsius C. N'ihi nnukwu ihe akụrụngwa limestone buru ibu ma ọ bụ nkesa okpomọkụ na-ezighi ezi n'ime kiln n'oge a na-agbakọta, wayo na-enwekarị lime a na-agbaghị ọkụ na lime a gbanyere ọkụ. Calcium carbonate na lime n'okpuru ọkụ adịghị emebi emebi kpamkpam, ọ nweghịkwa ike na-arụkọ ọrụ ọnụ n'oge a na-eji ya eme ihe, nke na-enweghị ike inye ike zuru oke maka putty, na-ebute mwepụ ntụ ntụ nke na-esighị ike na ike nke putty.
2. Ọdịnaya dị elu nke calcium hydroxide na ntụ ntụ calcium, nke ka mma nke siri ike nke putty mepụtara. N'ụzọ megidere nke ahụ, na-ebelata ọdịnaya nke calcium hydroxide na ntụ ntụ calcium ash, nke ka njọ nke siri ike nke putty na ebe mmepụta, na-akpata nsogbu nke iwepụ ntụ ntụ na nkwụsị ntụ.
3. A na-ejikọta ntụ ntụ calcium ash na nnukwu nnukwu calcium ntụ ntụ, nke na-eme ka ọdịnaya nke ntụ ntụ calcium dị ntakịrị iji nye ike na ike zuru ezu na putty, na-eme ka putty daa ntụ ntụ. Isi ọrụ nke ntụ ntụ putty bụ ijigide mmiri, nye mmiri zuru oke maka ike siri ike nke ntụ calcium calcium, ma hụ na mmetụta siri ike zuru ezu. Ọ bụrụ na enwere nsogbu na ogo hydroxypropyl methylcellulose ma ọ bụ ọdịnaya dị irè dị ala, enweghi ike inye mmiri zuru ezu, nke ga-eme ka ike sie ike na-ezughị ezu ma mee ka putty dobe ntụ ntụ.
Enwere ike ịchọta ya site na nke dị n'elu na àgwà hydroxypropyl methylcellulose dị nnọọ njọ na enweghị ike nweta mmetụta ụfọdụ, na putty ntụ ntụ ga-ada. Isi ihe kpatara ya bụ onye arịrịọ isi awọ calcium dị arọ.
