Ulwazi lwesodium carboxymethylcellulose

I-Sodium carboxymethylcellulose (i-NaCMC) yinto ephuma kwizinto ezininzi kunye ne-versatile cellulose efumana ukusetyenziswa kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa. Le khompawundi ivela kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zesityalo. I-sodium carboxymethyl cellulose yenziwa ngokuphendula i-cellulose kunye ne-sodium monochloroacetate kwaye ingathathi hlangothi. Iimveliso ezisisiphumo zinoluhlu lweempawu ezinqwenelekayo, ezizenza zixabiseke ekutyeni nakwiziselo, kumayeza, kwizinto zokuthambisa, ezilukiweyo nokunye.

Ulwakhiwo kunye nokwakheka:

I-sodium carboxymethyl cellulose yipolymer enyibilikayo emanzini kunye nesakhiwo somgca. Umqolo we-cellulose uguqulwa ngamaqela e-carboxymethyl aqaliswe yi-etherification. Iqondo lokuthatha indawo (DS) libhekisa kwiavareji yenani lamaqela e-carboxymethyl ngeyunithi ye-anhydroglucose kwikhonkco leselulosi. I-DS ichaphazela kakhulu iipropati zomzimba kunye neekhemikhali ze-NaCMC.

Inkqubo yokwenziwa kwemveliso:

Ukuveliswa kwe-sodium carboxymethylcellulose kubandakanya amanyathelo amaninzi. I-cellulose ngokuqhelekileyo ivela kwi-pulp yomthi okanye i-cotton kwaye ifakwe ngaphambili ukuze isuse ukungcola. Emva koko isabela nge-sodium monochloroacetate phantsi kweemeko ze-alkaline ukwazisa iqela le-carboxymethyl. Imveliso ebangelwayo ingathathi hlangothi ukufumana ifom yetyuwa ye-sodium ye-carboxymethylcellulose.

Iimpawu zomzimba kunye neekhemikhali:

Ukunyibilika: I-NaCMC inyibilika kakhulu emanzini, yenza isisombululo esicacileyo kunye ne-viscous. Oku kunyibilika luphawu oluphambili ekusetyenzisweni kwayo ngokubanzi kumashishini ahlukeneyo.

I-Viscosity: I-viscosity yesisombululo se-sodium carboxymethylcellulose inokulungelelaniswa ngokulawula iqondo lokutshintshwa kunye nokugxila. Le propati yenza ukuba ilungele izicelo ezifuna ukuqina okanye i-gelling.

Uzinzo: I-NaCMC ihlala izinzile kuluhlu olubanzi lwe-pH, oluphucula ukuguquguquka kwayo kwimixube eyahlukeneyo.

Ukwenza ifilimu: Ineempawu zokwenza ifilimu kwaye ingasetyenziselwa ukuvelisa iifilimu kunye neengubo kwiinkqubo ezahlukeneyo.

isicelo:

Ishishini lokutya neziselo:

Iarhente yokutyebisa:I-NaCMC iqhele ukusetyenziswa njenge-ejenti yokutyebisa kwiimveliso zokutya ezinje ngeesosi, izinxibo kunye neziselo.

Mzinzisi: Iyahlabailizes emulsions kunye nokunqunyanyiswa kwiimveliso ezifana ne-ayisikrimu kunye nezinxibo zesaladi.

Ukuphucula Ubume: I-NaCMC inika ukuthungwa okunqwenelekayo ekutyeni, ukuphucula umgangatho wako uwonke.iyeza:

Izibophelelo: Zisetyenzisiwenjengezibophelelo kwiinkqubo zethebhulethi ukuqinisekisa ukunyaniseka kwesakhiwo samacwecwe.

I-Viscosity modifier: ilungisa i-visUbuninzi bamalungiselelo olwelo ukunceda ukuhanjiswa kweziyobisi.

Izithambiso kunye nokhathalelo lomntu:

I-Stabilizers: Isetyenziselwa ukuzinzisa i-emulsions kwi-creams kunye ne-lotions.
Izityebi: Yandisa i-viscosity yeshampu, intlama yamazinyo kunye nezinye iimveliso zokhathalelo lomntu.
impahla:

I-ajenti yokulinganisa: isetyenziselwa ukwenza ubungakanani belaphu ukuphucula ukomelela kunye nokuguda kweentsinga ngexesha lenkqubo yokuluka.

Intlama yokuprinta: Isebenza njenge-thickener kunye ne-rheology modifier kwi-textile yokuprinta intlama.
Ishishini leoli negesi:

Ulwelo lokwemba: I-NaCMC yiisetyenziswa njenge tackifier ekugrumbeni ulwelo ukwandisa iimpawu zayo rheological.

Ishishini lephepha:

I-ejenti yokwambathisa: isetyenziselwa ukugquma ngephepha ukuphucula iipropati zomphezulu.
elinye ishishini:

Unyango lwamanzi: Isetyenziswe kwiinkqubo zokunyanga amanzi ngenxa yeempawu zayo zokujikeleza.

Isicoci: Sisebenza njengesizinzisi kwimixube ethile yesicoci.

Ukhuseleko kunye nemimiselo:

I-sodium carboxymethylcellulose yaziwa ngokubanzi njengekhuselekile (GRAS) ukuze isetyenziswe ekutyeni nakwizicelo zamayeza. Ihambelana nemigangatho yolawulo kunye neenkcukacha ezibekwe yi-arhente ezininzi, kubandakanywa i-US Food and Drug Administration (FDA) kunye ne-European Food Safety Authority (EFSA).

I-sodium carboxymethyl cellulose yipolymer esebenzayo enoluhlu olubanzi lwezicelo kumashishini ahlukeneyo. Inhlanganisela yayo ekhethekileyo ye-solubility, i-viscosity control, ukuzinza kunye neempawu zokwenza ifilimu yenza ukuba ibe yinto ebalulekileyo kwiindlela ezahlukeneyo zokuqulunqa. Njengoko ishishini liqhubeka nokuvela, imfuno ye-sodium carboxymethylcellulose kusenokwenzeka ukuba iqhubeke ngenxa yokuguquguquka kwayo kunye negalelo ekuphuculeni ukusebenza kwemveliso kwizicelo ezahlukeneyo.
