I-Cellulose Ether Encibilika Ngokushesha/Kancane (Ukwelashwa Komphezulu)

Ukuhlukaniswa kwe-Cellulose Ether

I-cellulose ether yigama elijwayelekile lochungechunge lwemikhiqizo ekhiqizwa ukusabela kwe-alkali cellulose kanye ne-etherifying agent ngaphansi kwezimo ezithile. Lapho i-alkali cellulose ithathelwa indawo yi-etherifying agents ezahlukene, kuzotholakala ama-ether e-cellulose ahlukene.

Ngokwezakhiwo ze-ionization zezinto ezithatha indawo, ama-cellulose ether angahlukaniswa ngezigaba ezimbili: i-ionic (njenge-carboxymethyl cellulose) kanye ne-nonionic (njenge-methyl cellulose).

Ngokusho kohlobo lwe-substituent, i-cellulose ether ingahlukaniswa ibe yi-monoether (njenge-methyl cellulose) kanye ne-mixed ether (njenge-hydroxypropyl methyl cellulose).

Ngokusho kokuncibilika okuhlukile, kungahlukaniswa kube ukuncibilika kwamanzi (njenge-hydroxyethyl cellulose) kanye nokuncibilika kwe-organic solvent (njenge-ethyl cellulose).

Ama-ether e-cellulose ancibilika emanzini asetshenziswa kuma-mortar axutshwe okomile ahlukaniswe ngama-ether e-cellulose ancibilika ngokushesha kanye nama-ether e-cellulose ancibilika kancane aphathwe ebusweni.

Ukuphi umehluko wabo? Futhi ungayilungisa kanjani kahle ibe yisisombululo samanzi esingu-2% sokuhlola i-viscosity?

Kuyini ukwelashwa kobuso?

Umphumela ku-cellulose ether?

kuqala

Ukwelashwa kwendawo kuyindlela yokwakha ungqimba olungaphezulu ngokwenziwa ebusweni bento eyisisekelo enezakhiwo zemishini, zomzimba nezamakhemikhali ezihlukile kwezesisekelo.

Inhloso yokwelashwa kobuso be-cellulose ether ukulibazisa isikhathi sokuhlanganisa i-cellulose ether namanzi ukuze kuhlangatshezwane nezidingo zokuqina kancane kweminye i-mortars yopende, kanye nokwandisa ukumelana nokugqwala kwe-cellulose ether nokuthuthukisa ukuzinza kwesitoreji.

Umehluko lapho amanzi abandayo ehlelwe ngesisombululo samanzi esingu-2%:

I-cellulose ether ephathwe ebusweni ingasakazeka ngokushesha emanzini abandayo futhi akulula ukuyihlanganisa ngenxa yokuqina kwayo okuhamba kancane;

I-cellulose ether ngaphandle kokwelashwa kwendawo, ngenxa yokuqina kwayo okusheshayo, izoqina ngaphambi kokuba ihlakazeke ngokuphelele emanzini abandayo, futhi ithambekele ekuhlanganeni.

Ungayilungiselela kanjani i-cellulose ether engaphathwanga ebusweni?

1. Okokuqala faka inani elithile le-cellulose ether engaphathwanga ebusweni;

2. Bese ufaka amanzi ashisayo cishe kuma-degree Celsius angu-80, isisindo siyingxenye yesithathu yomthamo wamanzi odingekayo, ukuze ikwazi ukuvuvukala nokusabalala ngokugcwele;

3. Okulandelayo, thela kancane amanzi abandayo, isisindo siyizingxenye ezimbili kwezintathu zamanzi asele adingekayo, qhubeka uvuselela ukuze unamathele kancane, futhi ngeke kube khona ukuhlangana;

4. Ekugcineni, ngaphansi kwesimo sesisindo esilinganayo, yifake ebhavini lamanzi elinokushisa okulinganayo kuze kube yilapho izinga lokushisa lehla liye kuma-degree Celsius angama-20, bese kwenziwa ukuhlolwa kwe-viscosity!
