Yintoni umahluko phakathi kweCMC kunye neselulosi?

ICarboxymethylcellulose (CMC) kunye neselulosi zombini ziipolysaccharides ezineempawu ezahlukeneyo kunye nokusetyenziswa. Ukuqonda iiyantlukwano zabo kufuna ukuhlola izakhiwo zabo, iipropati, imvelaphi, iindlela zokuvelisa, kunye nokusetyenziswa.

ISelulosi:

1. Inkcazo kunye nesakhiwo:

I-Cellulose yi-polysaccharide yendalo eyenziwe ngamatyathanga ahlukeneyo eyunithi ye-β-D-glucose edityaniswe ngamabhondi e-β-1,4-glycosidic.

Yeyona nxalenye yolwakhiwo oluphambili lweendonga zeeseli zesityalo, ukubonelela amandla kunye nokuqina.

2. Umthombo:

I-Cellulose ininzi kwindalo kwaye ngokuyinhloko iphuma kwimithombo yezityalo ezifana neenkuni, umqhaphu kunye nezinye izinto ze-fibrous.

3. Imveliso:

Imveliso ye-cellulose ibandakanya ukukhupha i-cellulose kwizityalo kwaye emva koko iqhutywe ngeendlela ezifana ne-chemical pulping okanye ukugaya ngomatshini ukufumana i-fiber.

4. Ukusebenza:

Kwimo yayo yendalo, i-cellulose ayinyibiliki emanzini kunye nezona zinyibilikisiweyo zininzi.

Inamandla aphezulu okuxinana, okwenza ukuba ilungele usetyenziso apho amandla kunye nokuqina kubaluleke kakhulu.

I-Cellulose i-biodegradable kwaye ihambelana nokusingqongileyo.

5. Isicelo:

I-Cellulose ineendlela ezahlukeneyo zokusetyenziswa, kubandakanywa ukuveliswa kwephepha kunye nebhodi, iingubo, iiplastiki ezisekelwe kwi-cellulose, kunye ne-fiber supplement.

I-Carboxymethylcellulose (CMC):

1. Inkcazo kunye nesakhiwo:

I-Carboxymethylcellulose (CMC) iphuma kwi-cellulose apho amaqela e-carboxymethyl (-CH2-COOH) angeniswa kwi-backbone ye-cellulose.

2. Imveliso:

I-CMC idla ngokuveliswa ngokunyanga i-cellulose nge-chloroacetic acid kunye ne-alkali, ekhokelela ekutshintshweni kwamaqela e-hydroxyl kwi-cellulose ngamaqela e-carboxymethyl.

3. Ukunyibilika:

Ngokungafaniyo ne-cellulose, i-CMC i-soluble yamanzi kwaye yenza isisombululo se-colloidal okanye ijeli ngokuxhomekeke kugxininiso.

4. Ukusebenza:

I-CMC ineempawu zombini ze-hydrophilic kunye ne-hydrophobic, iyenza ilungele usetyenziso oluhlukeneyo kumacandelo okutya, amayeza kunye namashishini.

Inamandla okwenza ifilim kwaye inokusetyenziswa njengento etyebisayo okanye ezinzileyo.

5. Isicelo:

I-CMC isetyenziswa kushishino lokutya njengento etyebisayo, ukuzinzisa kunye ne-emulsifier kwiimveliso ezifana ne-ayisikrimu kunye nokunxitywa kwesaladi.

Kumachiza, i-CMC isetyenziswa njenge-binder kwi-tablet formulations.

Isetyenziswa kwiinkqubo zokulinganisa kunye nokugqiba kwishishini lelaphu.

umahluko:

1. Ukunyibilika:

I-cellulose ayinyibiliki emanzini, ngelixa i-CMC inyibilika emanzini. Lo mahluko kwi-solubility yenza i-CMC ibe yinto eguquguqukayo kwiintlobo ezahlukeneyo zezicelo, ngakumbi kumashishini apho iindlela ezisekelwe emanzini zikhethwayo.

2. Inkqubo yokuvelisa:

Ukuveliswa kwe-cellulose kubandakanya ukutsalwa kunye nokulungiswa kwezityalo, ngelixa i-CMC yenziwe ngenkqubo yokuguqulwa kweekhemikhali ezibandakanya i-cellulose kunye ne-carboxymethylation.

3. Ulwakhiwo:

I-Cellulose ine-linear and unbranched structure, ngelixa i-CMC inamaqela e-carboxymethyl eqhotyoshelwe kwi-cellulose backbone, inika isakhiwo esilungisiweyo kunye ne-solubility ephuculweyo.

4. Isicelo:

I-Cellulose isetyenziswa ikakhulu kumashishini afana nephepha kunye neempahla ezilukiweyo apho amandla ayo kunye nokunganyibiliki kwayo kubonelela ngeenzuzo.

I-CMC, kwelinye icala, isetyenziswa kuluhlu olubanzi lwamashishini, kubandakanya ukutya, amayeza kunye nezithambiso, ngenxa yokunyibilika kwamanzi kunye nokuguquguquka.

5. Iimpawu zomzimba:

I-Cellulose iyaziwa ngokuba namandla kunye nokuqina kwayo, igalelo kwingqibelelo yesakhiwo sezityalo.

I-CMC izuza njengelifa ezinye iipropathi zeselulosi kodwa ikwanazo nezinye, ezinje ngokukwazi ukwenza iijeli nezisombululo, inika uluhlu olubanzi lwezicelo.

Nangona i-cellulose kunye ne-carboxymethyl cellulose zinemvelaphi efanayo, izakhiwo zabo ezahlukeneyo kunye neempawu ziye zakhokelela kwizicelo ezahlukeneyo kumashishini ahlukeneyo. Amandla e-Cellulose kunye nokunganyibiliki kunokuba luncedo kwezinye iimeko, ngelixa ukunyibilika kwamanzi kwe-CMC kunye nesakhiwo esilungisiweyo sisenza isithako esibalulekileyo kuluhlu lweemveliso kunye nokuqulunqwa.
