Ọrụ nke hydroxypropyl methylcellulose na putty

Ọrụ nke hydroxypropyl methylcellulose na putty

Site na ịkagbu, idobe mmiri na iwulite ọrụ atọ.

Ịkpụ akpụ: Enwere ike ime ka cellulose sie ike iji kwụsị, mee ka ngwọta ahụ dị otu ma dịkwa mma, ma gbochie ịda mba. Nchekwa mmiri: Mee ka ntụ putty kpọọ nkụ nwayọ nwayọ, ma nyere aka na mmeghachi omume nke calcium ntụ n'okpuru ọrụ mmiri. Nhazi: Cellulose nwere mmetụta na-eme ka mmanụ dị mma, nke nwere ike ime ka ntụ putty nwee ezigbo ọrụ. Hydroxypropyl methylcellulose anaghị esonye na mmeghachi omume kemịkalụ ọ bụla ma na-arụ naanị ọrụ enyemaka. A na-agbakwunye ntụ putty na mmiri iji mee ka mgbidi ahụ dị n'otu, nke bụ mmeghachi omume kemịkalụ, n'ihi na e nwere mmepụta nke ihe ọhụrụ calcium carbonate. Isi ihe dị na ntụ ntụ calcium ntụ bụ: ngwakọta nke calcium hydroxide Ca(OH)2, calcium oxide CaO na obere calcium carbonate CaCO3. Calcium ntụ na-emepụta calcium carbonate n'okpuru ọrụ nke CO2 na mmiri na ikuku, ebe hydroxypropyl methyl Cellulose na-ejide mmiri ma na-enyere aka na mmeghachi omume ka mma nke calcium ntụ, nke onwe ya anaghị esonye na mmeghachi omume ọ bụla.

Anyị na-ebu ụzọ nyochaa ihe kpatara ntụ ntụ nke putty si na ihe ndị e ji esi nri nke putty: ntụ ntụ calcium ash, hydroxypropyl methylcellulose, ntụ ntụ calcium dị arọ, ntụ ntụ calcium mmiri

1. N'ime mmepụta n'ezie, iji mee ka ire ere ngwa ngwa, a na-amụba okpomọkụ calcination ruo 1000-1100 Celsius. N'ihi nnukwu nha nke ihe eji emepụta limestone ma ọ bụ nkesa okpomọkụ na-adịghị mma n'ime ọkụ n'oge calcination, lime na-enwekarị lime a na-ere n'okpuru ọkụ na lime a na-ere n'elu ọkụ. Calcium carbonate dị na lime a na-ere n'okpuru ọkụ anaghị ere kpamkpam, ọ nweghịkwa ike njikọ aka n'oge eji ya, nke na-enweghị ike inye ike njikọ zuru oke na putty, na-ebute mwepụ ntụ ntụ nke enweghị ike na ike nke putty kpatara.

2. Ka ọdịnaya calcium hydroxide dị n'ime ntụ calcium ntụ ahụ dị elu, otú ahụ ka ike putty a na-emepụta si ka mma. N'ụzọ megidere nke ahụ, obere ọdịnaya calcium hydroxide dị n'ime ntụ calcium ntụ ahụ, otú ahụ ka ike putty ahụ si ka njọ n'ebe a na-emepụta ya, nke na-ebute nsogbu nke iwepụ ntụ na iwepụ ntụ ahụ.

3. A na-agwakọta ntụ ntụ calcium ntụ ntụ na nnukwu ntụ calcium dị arọ, nke na-eme ka ọdịnaya nke ntụ ntụ calcium ntụ dị ala nke na ọ gaghị enye putty ike na ike zuru oke, na-eme ka putty daa ntụ. Isi ọrụ nke ntụ ntụ putty bụ idobe mmiri, inye mmiri zuru oke maka ime ka ntụ ntụ calcium ntụ sie ike, ma hụ na ọ na-eme ka ọ sie ike nke ọma. Ọ bụrụ na nsogbu dị na ịdị mma nke hydroxypropyl methylcellulose ma ọ bụ na ọdịnaya dị irè dị ala, enweghị ike inye mmiri zuru oke, nke ga-eme ka ike ahụ ghara ịdị oke ma mee ka ntụ ntụ putty daa.

Site n'ihe ndị dị n'elu, a pụrụ ịchọpụta na ịdị mma nke hydroxypropyl methylcellulose adịghị mma nke ukwuu, ọ nweghịkwa ike imezu otu ihe ahụ, ntụ ntụ putty ga-adapụkwa. Isi ihe kpatara ya bụ calcium dị arọ.
