Kedu ihe dị iche n'etiti xanthan gum na HEC?

Xanthan gum na Hydroxyethyl cellulose (HEC) bụ hydrocolloids a na-ejikarị eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ, ihe ịchọ mma, na ngwaahịa nlekọta onwe onye. N'agbanyeghị na ha nwere ihe yiri onwe ha na ihe ha ji eme ihe, e nwere ọdịiche dị iche n'etiti ha abụọ.

Nhazi na Nhazi:

Xanthan chịngọm:
Xanthan chịngọmbụ polysaccharide sitere na ịgbakọ carbohydrates site na nje bacteria Xanthomonas campestris. O nwere otu glucose, mannose, na glucuronic acid, nke edobere n'ime nnukwu alaka. Ọkpụkpụ azụ nke xanthan gum nwere otu glucose na mannose ugboro ugboro, yana otu glucuronic acid na acetyl.

HEC (Hydroxyethyl Cellulose):
HECbụ ihe sitere na cellulose, nke bụ polima sitere n'okike nke a na-ahụ na mgbidi mkpụrụ osisi. N'ime mmepụta nke HEC, a na-emeghachi omume na ethylene oxide na cellulose iji webata otu hydroxyethyl n'ime ọkpụkpụ azụ cellulose. Mgbanwe a na-eme ka mmiri na-agbaze na ihe ndị dị ndụ nke cellulose dịkwuo mma.

Njirimara:

Xanthan chịngọm:
Viscosity: Xanthan gum na-enye mmiri mmiri oke viscosity ọbụlagodi na obere njupụta, na-eme ka ọ bụrụ ihe na-eme ka ọ sie ike nke ọma.
Omume ịkpụcha akpụcha: Ngwọta nwere xanthan chịngọm na-egosipụta àgwà ịkpụcha akpụcha, nke pụtara na ha na-ebelata ịcha akpụcha n'okpuru nrụgide ịkpụcha akpụcha ma weghachite ike ha mgbe ewepụchara nrụgide ahụ.
Ịkwụsi ike: Xanthan gum na-enye nkwụsi ike nye emulsions na nkwụsịtụ, na-egbochi nkewa nke usoro.
Ndakọrịta: Ọ dakọtara na ọtụtụ ọkwa pH ma nwee ike iguzogide okpomọkụ dị elu na-enweghị atụfu ihe ndị na-eme ka ọ sie ike.

HEC:
Viscosity: HEC na-arụkwa ọrụ dị ka ihe na-eme ka ọ sie ike ma na-egosipụta oke viscosity na mmiri mmiri.
Enweghị ionic: N'adịghị ka xanthan gum, HEC abụghị ionic, nke na-eme ka ọ ghara inwe mmetụta na mgbanwe na pH na ike ionic.
Ịkpụ ihe nkiri: HEC na-emepụta ihe nkiri doro anya mgbe a kpọrọ nkụ, nke na-eme ka ọ baa uru n'ọrụ dịka mkpuchi na ihe nrapado.
Nnu na-anabata nnu: HEC na-ejigide ike ya n'ihu nnu, nke nwere ike ịba uru na ụfọdụ usoro.

Ojiji:

Xanthan chịngọm:
Ụlọ Ọrụ Nri: A na-ejikarị Xanthan chịngọm eme ihe dị ka ihe na-eme ka ahụ sie ike, ihe na-eme ka ọ sie ike, na ihe na-eme ka ọ dị nro n'ọtụtụ ngwaahịa nri, gụnyere ihendori, ihe eji eme achịcha, ihe ndị e ji eme achịcha, na ihe ndị e ji mmiri ara ehi mee.
Ihe ịchọ mma: A na-eji ya eme ihe ịchọ mma dịka ude, ude mmanụ, na ihe e ji asa ezé iji nye ọwara na nkwụsi ike.
Mmanụ na Gas: A na-eji Xanthan chịngọm eme ihe n'ime mmiri ndị na-agbapụta mmiri n'ime ụlọ ọrụ mmanụ na gas iji chịkwaa viscosity na igbochi ihe siri ike.

HEC:
Agba na Mkpuchi: A na-eji HEC eme ihe nke ukwuu n'ime agba, ihe mkpuchi, na ihe nrapado e ji mmiri mee iji chịkwaa viscosity, melite àgwà mmiri, ma melite nhazi ihe nkiri.
Ngwaahịa Nlekọta Onwe: Ọ bụ ihe a na-ahụkarị na ngwaahịa nlekọta onwe onye dịka shampoos, ihe na-eme ka ọ dị nro, na ude n'ihi na ọ na-eme ka ọ sie ike ma na-eme ka ọ sie ike.
Ọgwụ: A na-eji HEC eme ihe dị ka ihe na-ejikọ ihe na mbadamba yana dị ka ihe na-eme ka ọ sie ike na ọgwụ mmiri mmiri.

Ihe dị iche:
Isi mmalite: A na-emepụta xanthan chịngọm site na ịgbakọ nje bacteria, ebe a na-enweta HEC site na cellulose site na mgbanwe kemịkalụ.
Àgwà Ionic: Xanthan gum bụ anionic, ebe HEC abụghị ionic.
Mmetụta Nnu: Xanthan gum na-enwe mmetụta maka oke nnu, ebe HEC na-ejigide ike ya n'ihu nnu.
Nhazi ihe nkiri: HEC na-emepụta ihe nkiri doro anya mgbe akpọnwụrụ akpọnwụ, nke nwere ike ịba uru na mkpuchi, ebe xanthan gum anaghị egosipụta ihe onwunwe a.

Àgwà Viscosity: Ọ bụ ezie na ma xanthan gum na HEC na-enye oke viscosity, ha na-egosipụta àgwà rheological dị iche iche. Ngwọta xanthan chịngọm na-egosi àgwà shear-thinning, ebe ngwọta HEC na-egosipụtakarị omume Newtonian ma ọ bụ obere shear-thinning.
Ngwa: Ọ bụ ezie na e nwere ihe yiri ibe ha n'ọrụ, a na-ejikarị xanthan gum eme ihe n'ụlọ ọrụ nri na dịka ihe mgbakwunye mmiri mmiri, ebe HEC na-eji ya eme ihe nke ukwuu n'agba, ihe mkpuchi, na ngwaahịa nlekọta onwe onye.

ebe xanthan gum na HEC nwere ụfọdụ myirịta dị ka hydrocolloids eji eme ka usoro mmiri sie ike ma kwụsie ike, ha dị iche na isi mmalite ha, àgwà ionic, mmetụta nnu, njirimara imepụta ihe nkiri, na ojiji. Ịghọta ọdịiche ndị a dị oke mkpa maka ịhọrọ hydrocolloid kwesịrị ekwesị maka nhazi ụfọdụ na ihe onwunwe achọrọ.
