Cellulose Ether na-agbaze ngwa ngwa/nwayọọ nwayọọ (Ọgwụgwọ Elu)

Nhazi Cellulose Ether

Cellulose ether bụ okwu izugbe maka usoro ngwaahịa ndị a na-emepụta site na mmeghachi omume nke alkali cellulose na ihe na-eme ka ihe dị n'ime mmiri dị n'okpuru ọnọdụ ụfọdụ. Mgbe ejiri ihe na-eme ka ihe dị n'ime mmiri dị iche iche dochie alkali cellulose, a ga-enweta cellulose ether dị iche iche.

Dịka njirimara ionization nke ihe ndị na-anọchi ya si dị, enwere ike kewaa cellulose ethers n'ime ụdị abụọ: ionic (dịka carboxymethyl cellulose) na nonionic (dịka methyl cellulose).

Dịka ụdị ihe nnọchi si dị, enwere ike kewaa cellulose ether n'ime monoether (dịka methyl cellulose) na agwakọta ether (dịka hydroxypropyl methyl cellulose).

Dịka usoro mgbaze dị iche iche si dị, enwere ike kewaa ya ụzọ mgbaze mmiri (dịka hydroxyethyl cellulose) na usoro mgbaze organic (dịka ethyl cellulose).

A na-ekewa ether cellulose na-agbaze mmiri nke ejiri mee ihe n'ime ngwa agha akọrọ n'ime sel cellulose ethers nke na-agbaze ozugbo na nke a na-agwọ n'elu ya nke a na-agwọ n'oge na-agbaze.

Ebee ka ọdịiche ha dị? Kedu otu esi ahazi ya nke ọma ka ọ bụrụ ihe ngwọta mmiri 2% maka nnwale viscosity?

Gịnị bụ ọgwụgwọ elu?

Mmetụta dị na cellulose ether?

Ọgwụgwọ elu bụ ụzọ e si emepụta oyi akwa elu n'elu ihe e ji arụ ọrụ ntọala nke nwere ihe eji arụ ọrụ, ihe anụ ahụ na ihe kemịkalụ dị iche na nke ntọala.

Ebumnuche nke ọgwụgwọ elu nke cellulose ether bụ igbu oge iji jikọta cellulose ether na mmiri iji mezuo ihe achọrọ iji mee ka ụfọdụ agba sie ike, yana ịbawanye iguzogide nchara nke cellulose ether ma melite iguzosi ike n'ezi ihe nchekwa.

Ihe dị iche mgbe ejiri mmiri mmiri 2% mee ka mmiri oyi dị:

Cellulose ether nke e ji elu mee nwere ike ịgbasa ngwa ngwa n'ime mmiri oyi ma ọ dịghị mfe ịgbakọta n'ihi na ọ na-agbagharị nwayọ nwayọ;

Cellulose ether na-enweghị ọgwụgwọ elu, n'ihi oke viscosity ya ngwa ngwa, ga-agbawa agbawa tupu a gbasaa ya kpamkpam na mmiri oyi, ọ na-adịkwa mfe ịgbakọta.

Kedu otu esi ahazi cellulose ether nke a na-anaghị agwọ n'elu?

1. Buru ụzọ tinye obere ego nke cellulose ether nke a na-agwọghị n'elu;

2. Tinye mmiri ọkụ na ihe dị ka ogo Celsius 80, ibu ya bụ otu ụzọ n'ụzọ atọ nke olu mmiri achọrọ, ka o wee nwee ike ịza ma gbasaa nke ọma;

3. Mgbe nke ahụ gasịrị, wụsa mmiri oyi nwayọ nwayọ, ibu ya bụ ụzọ abụọ n'ime atọ nke mmiri fọdụrụnụ achọrọ, na-akpali ya ka ọ na-arapara nwayọ nwayọ, ọ gaghịkwa enwe njikọta;

4. N'ikpeazụ, n'okpuru ọnọdụ nke nha nhata, tinye ya n'ime mmiri ịsa ahụ okpomọkụ mgbe niile ruo mgbe okpomọkụ ahụ dara ruo ogo Celsius 20, mgbe ahụ enwere ike ime ule viscosity!
