Ndeupi musiyano uripo pakati pexanthan chingamu neHEC?

Xanthan chingamu uye Hydroxyethyl cellulose (HEC) ese ari maviri anoshandiswa zvakanyanya hydrocolloids mumaindasitiri akasiyana, anosanganisira chikafu, mishonga, zvizorwa, uye zvigadzirwa zvekuchengeta munhu. Pasinei nekugovana zvimwe zvakafanana mumidziyo yavo uye mashandisirwo, pane misiyano yakasiyana pakati pezviviri izvi.

Kuumbwa uye Chimiro:

Xanthan Gum:
Xanthan chingamuipolysaccharide inotorwa kubva mukuviriswa kwemacarbohydrates nebhakitiriya Xanthomonas campestris. Inoumbwa neglucose, mannose, uye glucuronic acid units, yakarongedzwa mune yakanyanya matavi chimiro. Iyo musana we xanthan gum ine inodzokorora mayunitsi eglucose uye mannose, ine parutivi maketani eglucuronic acid uye acetyl mapoka.

HEC (Hydroxyethyl Cellulose):
HECinobva ku cellulose, inova polima inongoitika inowanikwa mumadziro esero rezvirimwa. Mukugadzirwa kweHEC, ethylene oxide inobatwa ne cellulose kuunza mapoka e hydroxyethyl pane cellulose musana. Uku kugadziridzwa kunowedzera kunyungudika kwemvura uye rheological properties ye cellulose.

Properties:

Xanthan Gum:
Viscosity: Xanthan chingamu inopa yakakwira viscosity kune aqueous mhinduro kunyangwe pakadzika kudzika, zvichiita kuti ive inoshanda gobvu mumiriri.
Shear-kuonda maitiro: Mhinduro dzine xanthan chingamu dzinoratidza shear-kuonda maitiro, zvichireva kuti ivo vanova vashoma viscous pasi pekuveura kushushikana uye kudzoreredza viscosity yavo kana kushushikana kwabviswa.
Kugadzikana: Xanthan gum inopa kugadzikana kune emulsions uye kumiswa, kudzivirira kuparadzaniswa kwechikamu.
Kugarisana: Inofambirana nehupamhi hwepH mazinga uye inogona kutsungirira tembiricha yakakwira pasina kurasikirwa nekukora kwayo.

HEC:
Viscosity: HEC inoshandawo seyakakora uye inoratidza yakakwira viscosity mumhinduro dzine aqueous.
Non-ionic: Kusiyana nexanthan gum, HEC haisi-ionic, iyo inoita kuti isanyanya kunetseka kuchinja mupH uye ionic simba.
Kugadzira firimu: HEC inoumba mafirimu akajeka kana akaomeswa, zvichiita kuti abatsire mumashandisirwo akadai semapeji uye anonamira.
Kushivirira kwemunyu: HEC inochengetedza viscosity yayo pamberi pemunyu, izvo zvinogona kubatsira mune mamwe maitiro.

Zvishandiso:

Xanthan Gum:
Indasitiri Yezvekudya: Xanthan chingamu inowanzoshandiswa seyakagadzikana, thickener, uye gelling agent mumhando dzakasiyana dzezvigadzirwa zvekudya, zvinosanganisira sosi, madhirezi, zvinhu zvekubheka, uye zvigadzirwa zvemukaka.
Cosmetics: Inoshandiswa mukugadzira zvizorwa semafuta, lotions, uye mushonga wemazino kupa viscosity uye kugadzikana.
Mafuta neGasi: Xanthan chingamu inoshandiswa mukuchera zvinwiwa muindasitiri yemafuta negasi kudzora viscosity uye kumisa solids.

HEC:
Paints and Coatings: HEC inoshandiswa zvakanyanya mumvura-based peints, coatings, uye adhesives kudzora viscosity, kunatsiridza kuyerera kwezvinhu, uye kuwedzera firimu kuumbwa.
Zvigadzirwa Zvekuchengetedza Pamunhu: Icho chinhu chakajairika muzvigadzirwa zvekuchengetedza munhu senge shampoos, maconditioner, uye makirimu nekuda kwekukora uye kudzikamisa zvivakwa.
Pharmaceuticals: HEC inoshandiswa sebhainda mukugadzirwa kwehwendefa uye seyakakora mumishonga yemvura.

Misiyano:
Kwakabva: Xanthan gum inogadzirwa nebhakitiriya kuvirisa, nepo HEC inotorwa kubva ku cellulose kuburikidza nekemikari shanduko.
Ionic Character: Xanthan gum is anionic, nepo HEC isiri-ionic.
Munyu Sensitivity: Xanthan gum inonzwa kune yakakwira munyu, nepo HEC inochengetedza viscosity yayo pamberi pemunyu.
Kugadzira Firimu: HEC inoumba mafirimu akajeka kana akaomeswa, ayo anogona kubatsira mukupfeka, nepo xanthan chingamu isingaratidzi ichi chivakwa.

Viscosity Behaviour: Nepo ese xanthan chingamu uye HEC inopa yakakwira viscosity, inoratidza akasiyana rheological maitiro. Xanthan chingamu mhinduro dzinoratidza shear-kuonda maitiro, nepo HEC mhinduro dzinowanzoratidza maitiro eNewtonian kana kupfava-kuveura-kutetepa.
Zvishandiso: Kunyange zvazvo kune kumwe kupindirana mumashandisirwo avo, xanthan gum inonyanya kushandiswa mumhizha yezvokudya uye sekuwedzera kwemvura yekuchera, asi HEC inowana kushandiswa kwakanyanya mumapende, machira, uye zvigadzirwa zvekuchengeta munhu.

nepo xanthan chingamu neHEC vachigovana zvimwe zvakafanana semahydrocolloids anoshandiswa kukora uye kudzikamisa masisitimu emvura, anosiyana mune kwaanobva, ionic hunhu, munyu senitivity, firimu-kugadzira zvinhu, uye maapplication. Kunzwisisa misiyano iyi kwakakosha pakusarudza iyo yakakodzera hydrocolloid kune chaiyo maumbirwo uye inodiwa zvivakwa.
