Menene bambanci tsakanin xanthan danko da HEC?

Xanthan danko da Hydroxyethyl cellulose (HEC) dukkansu hydrocolloids ana amfani dasu sosai a masana'antu daban-daban, gami da abinci, magunguna, kayan kwalliya, da samfuran kulawa na sirri. Duk da raba wasu kamanceceniya a cikin kaddarorinsu da aikace-aikacensu, akwai bambance-bambance daban-daban tsakanin su biyun.

Haɗawa da Tsarin:

Xanthan Gum:
Xanthan dankopolysaccharide ne wanda aka samo daga haɗuwar carbohydrates ta ƙwayoyin Xanthomonas campestris. Ya ƙunshi glucose, mannose, da raka'a na glucuronic acid, wanda aka tsara a cikin tsari mai rassa sosai. Kashin baya na xanthan danko ya ƙunshi maimaita raka'a na glucose da mannose, tare da sassan gefe na glucuronic acid da ƙungiyoyin acetyl.

HEC (Hydroxyethyl Cellulose):
HECwani abin da aka samu daga cellulose, wanda shine nau'in polymer na halitta wanda aka samo a cikin ganuwar kwayoyin halitta. A cikin samar da HEC, ethylene oxide yana amsawa tare da cellulose don gabatar da ƙungiyoyin hydroxyethyl akan kashin bayan cellulose. Wannan gyare-gyare yana haɓaka haɓakar ruwa da rheological Properties na cellulose.

Kaddarori:

Xanthan Gum:

Hali mai laushi mai laushi: Maganin da ke dauke da xanthan danko yana nuna hali mai laushi, ma'ana sun zama ƙasa da danko a ƙarƙashin damuwa mai ƙarfi kuma suna dawo da danko lokacin da aka cire damuwa.
Kwanciyar hankali: Xanthan danko yana ba da kwanciyar hankali ga emulsions da suspensions, hana rabuwa lokaci.
Daidaituwa: Yana dacewa da matakan pH masu yawa kuma yana iya jure yanayin zafi ba tare da rasa kaddarorinsa na kauri ba.

HEC:
Danko: HEC kuma yana aiki azaman mai kauri kuma yana nuna babban danko a cikin mafita mai ruwa.
Ba-ionic ba: Ba kamar xanthan danko ba, HEC ba shi da ionic, wanda ya sa ya rage damuwa ga canje-canje a cikin pH da ƙarfin ionic.
Yin Fim: HEC yana samar da fina-finai masu gaskiya lokacin da aka bushe, yana sa ya zama mai amfani a aikace-aikace irin su sutura da adhesives.
Haƙuri na gishiri: HEC yana kula da danko a gaban gishiri, wanda zai iya zama mai fa'ida a wasu hanyoyin.

Amfani:

Xanthan Gum:
Masana'antar Abinci: Ana amfani da Xanthan danko a matsayin mai daidaitawa, mai kauri, da wakilin gelling a cikin samfuran abinci iri-iri, gami da miya, tufa, kayan burodi, da kayayyakin kiwo.
Kayan shafawa: Ana amfani da shi a cikin kayan kwalliya irin su creams, lotions, da man goge baki don samar da danko da kwanciyar hankali.
Mai da Gas: Xanthan danko yana aiki a cikin hako ruwa a cikin masana'antar mai da iskar gas don sarrafa danko da kuma dakatar da daskararru.

HEC:
Paints da Coatings: Ana amfani da HEC da yawa a cikin fenti na tushen ruwa, sutura, da adhesives don sarrafa danko, inganta halayen kwarara, da haɓaka samar da fim.
Kayayyakin Kulawa na Keɓaɓɓu: Abu ne na gama gari a cikin samfuran kulawa na mutum kamar shamfu, kwandishana, da man shafawa saboda kauri da kaddarorin sa.
Pharmaceuticals: Ana amfani da HEC azaman mai ɗaure a cikin ƙirar kwamfutar hannu kuma azaman mai kauri a cikin magungunan ruwa.

Bambance-bambance:
Tushen: Xanthan danko ana samar da shi ta hanyar fermentation na kwayan cuta, yayin da HEC ke samuwa daga cellulose ta hanyar gyare-gyaren sinadarai.
Halin Ionic: Xanthan danko shine anionic, yayin da HEC ba ionic ba.
Sensitivity na Gishiri: Xanthan danko yana kula da yawan gishiri mai yawa, yayin da HEC ke kiyaye danko a gaban gishiri.
Tsarin Fim: HEC yana samar da fina-finai masu gaskiya lokacin da aka bushe, wanda zai iya zama fa'ida a cikin sutura, yayin da xanthan danko baya nuna wannan kadarar.

Halin Danko: Duk da yake duka xanthan danko da HEC suna ba da babban danko, suna nuna halaye daban-daban na rheological. Maganin Xanthan danko yana nuna halayen ɓacin rai, yayin da hanyoyin HEC gabaɗaya suna nuna halayen Newtonian ko ƙaramin ƙarfi-ƙara.
Aikace-aikace: Ko da yake akwai wasu zoba a cikin aikace-aikacen su, xanthan danko an fi amfani dashi a cikin masana'antar abinci kuma azaman ƙari mai hakowa, yayin da HEC ke samun amfani mai yawa a cikin fenti, sutura, da samfuran kulawa na sirri.

yayin da xanthan danko da HEC suna raba wasu kamance kamar yadda ake amfani da hydrocolloids don yin kauri da daidaita tsarin ruwa, sun bambanta a tushen su, halayen ionic, jin daɗin gishiri, abubuwan samar da fim, da aikace-aikace. Fahimtar waɗannan bambance-bambance yana da mahimmanci don zaɓar madaidaicin hydrocolloid don ƙayyadaddun ƙira da kaddarorin da ake so.
