Ngaba i-carboxymethyl cellulose yi-ether yeselulosi?

Intshayelelo yeCarboxymethyl Cellulose (CMC)

I-Carboxymethyl cellulose, ehlala ishunqulwa njenge-CMC, iphuma kwizinto ezininzi ze-cellulose, i-polymer ngokwemvelo efumaneka kwiindonga zeeseli zezityalo. Ifunyenwe ngokuguqulwa kweekhemikhali ze-cellulose, ngokuyinhloko ngokusungulwa kwamaqela e-carboxymethyl (-CH2-COOH) kwi-backbone ye-cellulose.

Ulwakhiwo neePropati

I-CMC igcina ulwakhiwo olusisiseko lwe-cellulose, oluyityathanga elilandelelanayo leemolekyuli zeglucose ezidityaniswe nge-β(1→4) iibhondi ze-glycosidic. Nangona kunjalo, ukuqaliswa kwamaqela e-carboxymethyl kunika iipropati ezininzi ezibalulekileyo kwi-CMC:

Ukunyibilika kwamanzi: Ngokungafaniyo neselulosi yendalo, enganyibilikiyo emanzini, iCMC inyibilika kakhulu kumanzi ashushu nabandayo ngenxa yobume be-hydrophilic bamaqela e-carboxymethyl.

I-Arhente eQinisayo: I-CMC sisixhobo sokutyebisa esisebenzayo, esenza izisombululo ze-viscous kwiindawo eziphantsi. Le propati iyenza ixabiseke kuluhlu olubanzi lwezicelo, kubandakanya ukutya, amayeza, kunye neemveliso zokhathalelo lomntu.

Ukukwazi ukwenza ifilimu: I-CMC inokwenza iifilimu xa ifakwe kwisisombululo, iyenza ibe luncedo kwizicelo apho kufuneka ifilimu encinci, eguquguqukayo, njengeengubo kunye nokunamathiswa.

Uzinzo kunye nokuhambelana: I-CMC izinzile kuluhlu olubanzi lwe-pH kunye neemeko zobushushu, iyenza ihambelane nezinye izithako ezahlukeneyo kwaye ifanelekile kwizicelo ezahlukeneyo.

Usetyenziso

Iipropati eziguquguqukayo ze-CMC zifumana isicelo kumashishini amaninzi:

Ishishini lokutya: I-CMC isetyenziswa ngokubanzi njengento etyebisayo, isizinzisi, kunye ne-emulsifier kwiimveliso zokutya ezifana neesosi, izinxibo, i-ayisikrimu, kunye nezinto zokubhaka. Iphucula ukuthungwa, umlomo, kunye nokuzinza kweshelufu.

Amachiza: Kuqulunqo lwamachiza, i-CMC isebenza njenge-binder, i-disintegrant, kunye ne-arhente yokukhululwa elawulwayo kwiipilisi kunye neepilisi. Ukukwazi ukwenza iigels ezizinzileyo kwenza ukuba kube luncedo kwimiqulu ye-topical efana ne-creams kunye ne-lotions.

IiMveliso zoNakekelo loMntu: I-CMC sisithako esiqhelekileyo kwiimveliso zokhathalelo lomntu ezifana nentlama yamazinyo, iishampu, kunye neekhrimu, apho isebenza njenge-thickener, stabilizer, kunye nokugcina ukufuma.

Umzi-mveliso wamaphepha: Kukwenza iphepha, i-CMC isetyenziswa njenge-arhente yokulinganisa umphezulu ukuphucula amandla ephepha, ukuguda, kunye nokwamkelwa kwe-inki. Ikwasebenza njengenkxaso yokugcina, inceda ukubopha amaqhekeza amancinci kunye nokuzalisa kwiphepha.

Umqhaphu: I-CMC iqeshwe kushicilelo lwelaphu kunye neenkqubo zokudaya njenge-thickener kunye ne-rheology modifier yokuprinta intlama kunye neebhafu zedayi.

UKwemba i-oyile: Kwishishini lokomba i-oyile, i-CMC yongezwa kwiincindi zokomba ukunika ulawulo lwe-viscosity, ukucutha ilahleko yolwelo, kunye nokuthambisa amasuntswana okomba.

Ukusetyenziswa ngokubanzi kwe-carboxymethyl cellulose kubangelwa yindibaniselwano ekhethekileyo yeepropathi, eyenza ukusetyenziswa kwayo kwiinkalo ezahlukeneyo. Ukonakaliswa kwayo kwezinto eziphilayo kunye nokungabi yingozi ngakumbi kunegalelo kwisibheno sayo njengenye indlela ezinzileyo kunye neyokusingqongileyo kwiipholima zokwenziwa kwizicelo ezininzi.

I-carboxymethyl cellulose ngokwenene yi-ether yeselulosi enoluhlu olubanzi lwezicelo ngenxa yokunyibilika kwayo emanzini, iipropathi zokujiya, ukuzinza, kunye nokuhambelana nezinye izinto. Ukubaluleka kwayo kuthungelana kuwo onke amashishini, oko kuyenza ibe licandelo elixabisekileyo kwiimveliso ezininzi kunye neenkqubo.
