Kedu otu esi eji hydroxypropyl methylcellulose?

A na-agbakwunye ya ozugbo n'oge mmepụta. Usoro a bụ usoro kachasị mfe na nke kacha nso na-ewe oge. Usoro ndị a kapịrị ọnụ bụ:

1. Tinye ụfọdụ mmiri na-esi esi na arịa na-akpali akpali nke nwere oke nrụgide siri ike (ngwaahịa hydroxyethyl cellulose bụ soluble na mmiri oyi, ya mere, tinye naanị mmiri oyi);

2. Gbanwee ihe na-akpali akpali na obere ọsọ, ma jiri nwayọọ nwayọọ na-agbanye ngwaahịa ahụ n'ime akpa akpa;

3. Gaa n'ihu na-akpali akpali ruo mgbe ihe niile na-agbanye;

4. Tinye mmiri oyi zuru oke ma nọgide na-akpali ruo mgbe ngwaahịa niile agbazere (nghọta nke ngwọta doro anya na-abawanye);

5. Mgbe ahụ tinye ihe ndị ọzọ na usoro.

Kwadebe mmanya na-egbu nne maka ojiji: Usoro a bụ ịkwadebe ngwaahịa ahụ n'ime mmanya nne nwere nnukwu uche, wee tinye ya na ngwaahịa ahụ. Uru ya bụ na ọ nwere mgbanwe dị ukwuu ma nwee ike itinye ya ozugbo na ngwaahịa emechara. Nzọụkwụ ndị a bụ otu (1-3) na usoro mgbakwunye ozugbo. Mgbe ngwaahịa ahụ zuru oke, hapụ ya ka ọ guzoro maka oyi eke ka ọ gbazee, wee kpalite nke ọma tupu ejiri ya. Ekwesiri iburu n'uche na a ga-agbakwunye onye na-ahụ maka antifungal na nne mmanya ozugbo enwere ike.

Iji ngwakọta akọrọ akọrọ: Mgbe ị gwakọtachara ngwaahịa ntụ ntụ na ihe ntụ ntụ (dị ka simenti, ntụ ntụ gypsum, ụrọ seramiiki, wdg), gbakwunye mmiri kwesịrị ekwesị, ma kpochaa ma kpalie ruo mgbe ngwaahịa ahụ gbazere kpamkpam.

Mgbasa nke ngwaahịa mmiri oyi na-agbaze: ngwaahịa mmiri oyi nwere ike ịgbakwunye na mmiri oyi maka mgbaze. Mgbe ịgbakwunye mmiri oyi, ngwaahịa ahụ ga-ada ngwa ngwa. Mgbe mmiri gasịrị ruo oge ụfọdụ, malite ịkpali ruo mgbe agbazere kpamkpam.

Akpachara anya mgbe ị na-akwadebe ngwọta
