Ngwa ngwa/Ọdị nwayọọ na-agbari Cellulose Ether (Ọgwụgwọ dị n'elu)

Cellulose Ether nhazi ọkwa

Cellulose ether bụ okwu n'ozuzu maka usoro ngwaahịa na-emepụta site na mmeghachi omume nke cellulose alkali na etherifying n'okpuru ọnọdụ ụfọdụ. Mgbe alkali cellulose na-eji ihe dị iche iche etherifying dochie ya, a ga-enweta ihe dị iche iche cellulose ethers.

Dị ka ionization Njirimara nke nnọchi, cellulose ethers nwere ike kewaa ụzọ abụọ: ionic (dị ka carboxymethyl cellulose) na nonionic (dị ka methyl cellulose).

Dị ka ụdị nnọchi, ether cellulose nwere ike kewaa monoether (dị ka methyl cellulose) na ngwakọta ether (dị ka hydroxypropyl methyl cellulose).

Dị ka solubility dị iche iche si dị, enwere ike kewaa ya na mmiri solubility (dị ka hydroxyethyl cellulose) na organic mgbaze solubility (dị ka ethyl cellulose).

A na-ekewa ethers cellulose na-agbaze mmiri nke a na-eji na ngwa ngwa agwakọta akọrọ n'ime ngwa ngwa na-agbaze na elu-na-egbu oge-agbaze cellulose ethers.

Ebee ka ndịiche ha dị? Kedu ka esi ahazi ya nke ọma ka ọ bụrụ ngwọta mmiri 2% maka ule viscosity?

Gịnị bụ ọgwụgwọ elu?

Mmetụta na cellulose ether?

Ngwọta dị n'elu bụ usoro nke akpụ akpụ oyi akwa n'elu ihe mgbakwasị ụkwụ nwere nrụ arụ, anụ ahụ na kemịkal dị iche na nke isi.

Ebumnuche nke ọgwụgwọ elu nke cellulose ether bụ igbu oge oge ijikọta cellulose ether na mmiri iji gboo ngwa ngwa ngwa ngwa chọrọ nke ụfọdụ ụrọ agba, yana ịkwalite nguzogide corrosion nke cellulose ether ma melite nkwụsi ike nchekwa.

Ọdịiche dị iche iche mgbe edobere mmiri oyi na ngwọta mmiri 2%:

Ether cellulose nke a na-eme n'elu nwere ike ịgbasa ngwa ngwa na mmiri oyi ma ọ dịghị mfe ịgbasa n'ihi viscosities ya dị nwayọọ;

Cellulose ether na-enweghị ọgwụgwọ elu, n'ihi viscosities ngwa ngwa ya, ga-adị viscous tupu agbasasị ya kpamkpam na mmiri oyi, ọ na-adịkarịkwa ka agglomeration.

Kedu ka esi ahazi cellulose ether na-adịghị agwọ ọrịa?

1. Mbụ tinye na ụfọdụ ego nke cellulose ether na-abụghị elu-emeso;

2. Mgbe ahụ gbakwunye mmiri ọkụ na ihe dị ka ogo 80 Celsius, ịdị arọ bụ otu ụzọ n'ụzọ atọ nke mmiri mmiri achọrọ, ka o wee nwee ike ịgbasa ma gbasaa;

3. Na-esote, jiri nwayọọ nwayọọ wụsa na mmiri oyi, ịdị arọ bụ ụzọ abụọ n'ụzọ atọ nke mmiri fọdụrụnụ achọrọ, na-akpali akpali iji mee ka ọ na-arapara nwayọọ nwayọọ, ọ gaghịkwa enwe agglomeration;

4. N'ikpeazụ, n'okpuru ọnọdụ nha nha nha, tinye ya n'ime mmiri ịsa mmiri na-ekpo ọkụ mgbe niile ruo mgbe okpomọkụ na-adaba na 20 degrees Celsius, mgbe ahụ, enwere ike ịme ule viscosity!
