I-Xanthan gum, eyaziwa nangokuthi i-Hanseum gum, iwuhlobo lwe-microbial exopolysaccharide ekhiqizwa yi-Xanthomnas campestris ngobunjiniyela bokuvutshelwa kusetshenziswa ama-carbohydrates njengento eluhlaza eyinhloko (njengesitashi sombila).Ine-rheology eyingqayizivele, ukuncibilika kwamanzi okuhle, ukushisa nokuqina kwe-asidi-base, futhi inokuhambisana okuhle nezinhlobonhlobo zikasawoti, njenge-ejenti yokuqina, i-suspension agent, i-emulsifier, i-stabilizer, ingasetshenziswa kabanzi ekudleni, uphethiloli, imithi kanye nokunye. izimboni ezingaphezu kuka-20, okwamanje iyisilinganiso sokukhiqiza esikhulu kunazo zonke emhlabeni kanye ne-microbial polysaccharide esetshenziswa kakhulu.
Izakhiwo:I-Xanthan gum iyimpushana esusekayo ephuzi kuya kokumhlophe, iyanuka kancane.Incibilika emanzini abandayo nashisayo, isixazululo esingathathi hlangothi, imelana nokubanda nokuncibilika, ayincibiliki ku-ethanol.Ihlakaza ngamanzi bese i-emulsifiers ibe yi-hydrophilic viscous colloid ezinzile.
Isicelo:Nge-rheology yayo engavamile, ukuncibilika kwamanzi okuhle, nokuzinza okungavamile ngaphansi kwezimo zokushisa kanye ne-acid-base, i-xanthan gum isiyingxenye ebaluleke kakhulu ekusetshenzisweni okubanzi.Njenge-ejenti yokuqina, i-suspension agent, emulsifier, ne-stabilizer, isithole indlela yayo ezimbonini ezingaphezu kuka-20, ezihlanganisa ukudla, uphethiloli, imithi, nezinye eziningi.
Imboni yokudla ibe ngomunye wabahlomuli abakhulu bamakhono angavamile we-xanthan gum.Ikhono layo lokuthuthukisa ukuthungwa nokuvumelana kwemikhiqizo yokudla lenze kwaba ukukhetha okudumile phakathi kwabakhiqizi.Noma ngabe ikusoso, okokugqoka, noma izimpahla zokubhaka, i-xanthan gum iqinisekisa ukuzwakala komlomo okubushelelezi nokukhangayo.Ukuhambisana kwayo nosawoti abahlukahlukene kunomthelela nakakhulu ekwaziseni kwayo izinto ezihlukahlukene ekulungiseni ukudla.
Embonini ye-petroleum, i-xanthan gum idlala indima ebalulekile ekubhobolweni nasekuphuleni uketshezi.Izici zayo eziyingqayizivele ze-rheological zenza kube isithasiselo esihle, sithuthukisa i-viscosity yamanzi nokuzinza.Ukwengeza, isebenza njenge-ejenti yokulawula ukuhlunga, ukunciphisa ukwakheka kwamakhekhe okuhlunga ngesikhathi sokumba.Ikhono layo lokusebenza ngaphansi kwezimo zokushisa ezidlulele nezingcindezi kwenze kwaba ukukhetha okuthandwayo phakathi kochwepheshe be-oilfield.
Umkhakha wezokwelapha nawo uzuza kakhulu ezintweni ezingavamile ze-xanthan gum.Ukuziphatha kwayo kwe-rheological kuvumela ukukhululwa kwezidakamizwa okulawulwayo, okuyenza ibe isithako esifanelekile ekwakhiweni kwemithi.Ngaphezu kwalokho, i-biocompatibility yayo kanye ne-biodegradability iyenza ifanelekele ukusetshenziswa kwezokwelapha okuhlukahlukene njengokugqokwa kwamanxeba kanye nezinhlelo ezilawulwayo zokulethwa kwezidakamizwa.
Ngaphandle kwezimboni ezishiwo ngenhla, i-xanthan gum ithola indlela yayo kweminye imikhakha eminingi, okuhlanganisa imboni yamakhemikhali yansuku zonke.Kusukela ku-toothpaste kuya kuma-shampoos, i-xanthan gum inomthelela ekuthunjweni okufunayo nokuzinza kwale mikhiqizo.
Ukusebenza kwezohwebo kwe-xanthan gum akunakuqhathaniswa uma kuqhathaniswa namanye ama-polysaccharides amancane.Ububanzi bayo bezinhlelo zokusebenza kanye nezakhiwo ezihlukile kukwenze kwaba isithako sokungena kubakhiqizi abangenakubalwa.Ayikho enye i-microbial polysaccharide engafanisa ukuguquguquka nokusebenza kwayo.

Isitoreji:I-Xanthan gum ingasetshenziswa kakhulu ekukhishweni kukawoyela, amakhemikhali, ukudla, imithi, ezolimo, odayi, izitsha zobumba, iphepha, izindwangu, izimonyo, ukwakhiwa nokukhiqiza iziqhumane nezinye izimboni ezingaphezu kuka-20 ezinhlotsheni eziyikhulu zemikhiqizo.Ukuze kube lula ukugcinwa nokuthutha, ngokuvamile kwenziwa imikhiqizo eyomile.Ukomiswa kwayo kunezindlela zokwelashwa ezihlukene: ukomisa nge-vacuum, ukomisa izigubhu, ukomisa isifutho, ukomisa umbhede owenziwe ngamanzi kanye nokomisa umoya.Ngenxa yokuthi iyinto engezwani nokushisa, ayikwazi ukumelana nokwelashwa kokushisa okuphezulu isikhathi eside, ngakho-ke ukusetshenziswa kwe-spray drying kuyokwenza ukuthi kuncibilike kancane.Nakuba ukusebenza kahle okushisayo kokumisa izigubhu kuphezulu, ukwakheka kwemishini kuyinkimbinkimbi, futhi kunzima ukufeza ukukhiqizwa kwezimboni ezinkulu.Ukomiswa kombhede okunoketshezi ngama-inert sphere, ngenxa yakho kokubili ukushisa okuthuthukisiwe nokudluliswa kwenqwaba kanye nemisebenzi yokugaya nokuchoboza, isikhathi sokugcinwa kwempahla naso sifushane, ngakho-ke kufaneleka ukomisa izinto ze-viscous ezizwela ukushisa njenge-xanthan gum.
Izinyathelo zokuphepha zokusetshenziswa:
1. Lapho ulungiselela isisombululo se-xanthan gum, uma ukuhlakazeka kunganele, amahlule azovela.Ngaphezu kokuvuselela ngokugcwele, ingahlanganiswa ngaphambili nezinye izinto zokusetshenziswa, bese yengezwa emanzini ngenkathi ivuselela.Uma kusenzima ukuhlakazeka, i-solvent exubile ngamanzi ingangezwa, njengenani elincane le-ethanol.
2. I-Xanthan gum iyi-anionic polysaccharide, engasetshenziswa kanye nezinye izinto ze-anionic noma okungezona i-ionic, kodwa ayikwazi ukusebenzisana nezinto ze-cationic.Isixazululo saso sinokuhambisana okuhle kakhulu nokuzinza kusawoti omningi.Ukwengeza ama-electrolyte afana ne-sodium chloride ne-potassium chloride kungathuthukisa i-viscosity yayo nokuzinza.I-calcium, i-magnesium namanye ama-salts ane-bivalent abonise imiphumela efanayo ku-viscosity yabo.Lapho ukuhlushwa kukasawoti kungaphezu kuka-0.1%, i-viscosity ephelele iyafinyelelwa.Ukuhlushwa kukasawoti omningi akuthuthukisi ukuzinza kwesisombululo se-xanthan gum, futhi akuthinti i-rheology yayo, i-pH kuphela> Ngehora le-10 (imikhiqizo yokudla ayivamile ukuvela), usawoti wensimbi we-bivalent ubonisa ukuthambekela kokwenza ama-gel.Ngaphansi kwezimo ezine-acidic noma ezingathathi hlangothi, usawoti wayo wensimbi onga-trivalent njenge-aluminium noma amajeli ensimbi.Okuqukethwe okuphezulu kwe-monovalent metal salts kuvimbela i-gelation.
3. I-Xanthan gum ingahlanganiswa nama-thickeners amaningi okuhweba, afana ne-cellulose derivatives, isitashi, i-pectin, i-dextrin, i-alginate, i-carrageenan, njll. Uma ihlanganiswa ne-galactomannan, inomphumela we-synergistic ekwandiseni i-viscosity.
Ekugcineni, i-xanthan gum iyisimangaliso sangempela sesayensi yesimanje.Amakhono ayo ayingqayizivele njenge-ejenti ejiyayo, i-ejenti yokumiswa, i-emulsifier, nesiqinisi aguqule indlela izimboni ezihlukahlukene ezisebenza ngayo.Kusukela ekudleni esikudlayo kuye emithini esithembele kuyo, umthelela we-xanthan gum awunakuphikwa.Ukuthandwa kwayo kwezohwebo kanye nokusetshenziswa okubanzi kuyenza ibe yindlunkulu yeqiniso emhlabeni wezithako.Yamukela umlingo we-xanthan gum futhi uvule amandla ayo emikhiqizweni yakho namuhla.
