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 kuthubeleza kuwo onke amashishini, kuyenza ibe licandelo elixabisekileyo kwiimveliso ezininzi kunye neenkqubo.
