I-cellulose ether

Ukuhlukaniswa kwe-Cellulose Ether

I-Cellulose Ether yigama elijwayelekile lochungechunge lwemikhiqizo ekhiqizwa ukusabela kwe-Alkali Cellulose kanye ne-ejenti ethembisa ngaphansi kwezimo ezithile. Lapho u-Alkali Cellulose ethathelwa indawo ama-ejenti ahlukile aphelelisayo, azotholwa izithiyo ezihlukile ze-cellulose.

Ngokusho kwezakhiwo ze-Ionization zokufakaza ezikhundleni, izithiyo ze-cellulose zingahlukaniswa izigaba ezimbili: ionic (njenge-carboxymethyl celtulose) ne-nonionylls cellulose).

Ngokusho kohlobo lwe-substituent, i-cellulose ether ingahlukaniswa i-monoJe (njenge-methyl cellulose) futhi i-ether exubile (efana ne-hydroxypropylylyl methyl celtule).

Ngokuya nge-solubity ehlukene, ingahlukaniswa nge-solubility yamanzi (njenge-hydroxyethyl cellulose) kanye ne-organic solvent solubent (njenge-ethyl cellulose).

Abakwa-Celluble Celluluble Tallulose basetshenziswa odongeni obodwa okomile bahlukaniswe ngokuchithwa okusheshayo futhi baphathwe yi-cellulose ephethwe yi-cellulose.

Kukuphi umehluko wabo? Futhi ungakulungisa kanjani kahle kusisombululo esingamanzi esingu-2% sokuhlolwa kwe-viscosity?

Kuyini ukwelashwa komhlaba?

Umphumela ku-cellulose ether?

-yinhloko

Ukwelashwa okungaphezulu kuyindlela yokwakha ungqimba olungaphezulu ngaphezulu kwesisekelo sezinto ezinesisekelo esinezindawo ezisebenza ngomshini, zomzimba nezamakhemikhali ezihlukile kwalesosisekelo.

Inhloso yokwelashwa komhlaba we-cellulose ether ukubambezela isikhathi sokuhlanganisa isikhathi sokuhlanganisa ama-cellulose ether ngamanzi ukuze ahlangabezane nezidingo zokugqwala ezihamba kancane ze-cellulose ether futhi zithuthukise ukuqina kwesitoreji.

Umehluko lapho amanzi abandayo elungiselelwe ngesisombululo esingamanzi esingu-2%:

I-ether ephethwe yi-cellulose ephethwe ingaphezulu ingasabalalisa ngokushesha emanzini abandayo futhi akulula ukuthuthumela ngenxa ye-viscosities yayo ehamba kancane;

I-Cellulose Ether ngaphandle kokwelashwa komhlaba, ngenxa ye-viscosities yayo esheshayo, izosuselwa ngaphambi kokuthi ihlakazeke ngokuphelele emanzini abandayo, futhi ithambekele ekuhlanganiseni.

Ungasilungiselela kanjani i-ether ye-cellulose ephethwe ngaphandle komhlaba?

1. Okokuqala faka inani elithile le-ether ephethwe yi-cellulose ephethwe ngaphandle komhlaba;

2. Bese ufaka amanzi ashisayo cishe ama-degree angama-80, isisindo singelinye lesithathu levolumu yamanzi edingekayo, ukuze livuvukele ngokuphelele futhi lihlakazeke;

3. Okulandelayo, kancane uthele kancane emanzini abandayo, isisindo singamanzi amabili kwezintathu kwamanzi asele adingekayo, qhubeka uvuse ukushebekisa kancane, futhi ngeke kube khona okunamandla;
