Xanthan Gum: Isithako soMmangaliso seNjongo ezininzi

Xanthan gum, ekwabizwa ngokuba yiHanseum gum, luhlobo lwe-microbial exopolysaccharide eveliswa yi-Xanthomnas campestris ngobunjineli bokubiliswa kusetyenziswa iicarbohydrates njengeyona nto iphambili ekrwada (efana nesitatshi sombona).Ine-rheology ekhethekileyo, ukunyibilika kakuhle kwamanzi, ubushushu kunye nokuzinza kwe-asidi-base, kwaye ihambelana kakuhle neentlobo zeetyuwa, njenge-agent ekhulayo, i-agent yokunqunyanyiswa, i-emulsifier, i-stabilizer, inokusetyenziswa ngokubanzi ekutyeni, kwi-petroleum, amayeza kunye nezinye. ngaphezu kwemizi-mveliso engama-20, kungoku nje yeyona mveliso isikali sikhulu ehlabathini kwaye isetyenziswa ngokugqithisileyo i-polysaccharide yemicrobial.

Iinkcazelo ngeempawu:I-Xanthan gum iluhlaza tyheli ukuya kumgubo omhlophe oshukumayo, enevumba elincinane.Inyibilika kumanzi abandayo nashushu, isisombululo esingathathi hlangothi, simelana neqhwa kunye nokunyibilika, asinyibiliki kwi-ethanol.Isasaza ngamanzi kwaye i-emulsifies ibe yi-hydrophilic viscous colloid ezinzileyo.

Isicelo:Nge-rheology yayo ekhethekileyo, ukunyibilika kakuhle kwamanzi, kunye nokuzinza okukhethekileyo phantsi kweemeko zokushisa kunye ne-asidi-base, i-xanthan gum iye yaba yinto efunekayo kuluhlu olubanzi lwezicelo.Njenge-agent etyebisayo, i-suspension agent, i-emulsifier, kunye ne-stabilizer, ifumene indlela yayo kwimizi-mveliso engaphezu kwama-20, kuquka ukutya, i-petroleum, amayeza, kunye nezinye ezininzi.

Ishishini lokutya liye laba ngomnye wabaxhamli bexanthan gum amandla angaqhelekanga.Ukukwazi ukunyusa ukuthungwa kunye nokuhambelana kweemveliso zokutya kuye kwenza ukuba kube yinto ethandwayo phakathi kwabavelisi.Nokuba ikwisosi, kwimpahla yokunxiba, okanye kwimpahla yokubhaka, i-xanthan gum iqinisekisa umlomo ogudileyo nonomtsalane.Ukuhambelana kwayo neetyuwa ezahlukahlukeneyo kunegalelo ngakumbi ekusetyenzisweni kwayo ngeendlela ezahlukahlukeneyo ekulungiseni ukutya.

Kwishishini lepetroleum, i-xanthan gum idlala indima ebalulekileyo ekwembeni kunye nokuqhekeza ulwelo.Iimpawu zayo ezikhethekileyo ze-rheological zenza ukuba ibe yinto efanelekileyo yokudibanisa, ukuphucula i-viscosity yamanzi kunye nokuzinza.Ukongezelela, isebenza njenge-arhente yokulawula ukuhluza, ukunciphisa ukubunjwa kwamaqebelengwane okucoca ngexesha lokugaya.Ukukwazi ukusebenza phantsi kobushushu obugqithisileyo kunye neemeko zoxinzelelo kwenze ukuba kube yinto ekhethiweyo phakathi kweengcali ze-oilfield.

Icandelo lezonyango likwaxhamla kakhulu kwiipropati ezikhethekileyo ze-xanthan gum.Ukuziphatha kwayo kwe-rheological ivumela ukukhutshwa kweziyobisi ezilawulwayo, okwenza ukuba ibe yinto efanelekileyo kwimiqulu yamayeza.Ngaphaya koko, i-biocompatibility yayo kunye ne-biodegradability iyenza ifaneleke kwizicelo ezahlukeneyo zonyango ezinje ngokunxitywa kwamanxeba kunye neenkqubo ezilawulwayo zokuhanjiswa kweziyobisi.

Ngaphandle kwamashishini akhankanywe ngasentla, i-xanthan gum ifumana indlela yayo kwamanye amacandelo amaninzi, kuquka imboni yemichiza yemihla ngemihla.Ukusuka kwi-toothpaste ukuya kwi-shampoos, i-xanthan gum igalelo kwi-texture efunwayo kunye nokuzinza kwezi mveliso.

Ukuthengiswa kwe-xanthan gum akunakulinganiswa xa kuthelekiswa nezinye iipolysaccharides ezincinci.Uluhlu lwayo olubanzi lwezicelo kunye neepropathi ezikhethekileyo zenze ukuba kube yinto ehamba phambili kubavelisi abangenakubalwa.Ayikho enye i-polysaccharide ye-microbial inokuhambelana nokuguquguquka kwayo kunye nokusebenza kwayo.

Ugcino:I-Xanthan gum inokusetyenziswa kakhulu ekutsalweni kwe-oyile, iikhemikhali, ukutya, amayeza, ezolimo, idayi, iiseramikhi, amaphepha, amalaphu, izithambiso, ukwakhiwa kunye nokuvelisa iziqhushumbisi kunye namanye amashishini angaphezu kwama-20 kwiintlobo zeemveliso ezimalunga ne-100.Ukuze kube lula ukugcina kunye nokuthutha, ngokuqhelekileyo kwenziwa kwiimveliso ezomileyo.Ukomisa kwayo kuneendlela ezahlukeneyo zonyango: ukomisa i-vacuum, ukomisa igubu, ukomisa ukutshiza, ukomisa ibhedi enolwelo kunye nokomisa umoya.Ngenxa yokuba yinto ephazamisa ukushisa, ayikwazi ukumelana nonyango oluphezulu lweqondo lokushisa ixesha elide, ngoko ke ukusetyenziswa kwe-spray drying kuya kwenza ukuba kuncinci.Nangona ukusebenza kwe-thermal yokomisa i-drum kuphezulu, isakhiwo somatshini sinzima ngakumbi, kwaye kunzima ukufezekisa ukuveliswa kwemveliso enkulu.Ukomisa ibhedi egudisiweyo kunye ne-inert spheres, ngenxa yobushushu obongeziweyo kunye nokuhanjiswa kobuninzi kunye nokusila kunye nokutyumza imisebenzi, ixesha lokugcinwa kwezinto eziphathekayo lifutshane, ngoko ke lifanelekile ukomisa izinto ezibonakalayo ze-viscous ezifana ne-xanthan gum.

Imiqathango yokusetyenziswa:

1. Xa ulungiselela isisombululo se-xanthan gum, ukuba i-dispersion ayikwanelanga, ama-clots aya kubonakala.Ukongeza ukuvuselela ngokupheleleyo, kunokuxutywa kwangaphambili kunye nezinye izinto eziluhlaza, kwaye zongezwa emanzini ngelixa uvuselela.Ukuba kusenzima ukusabalalisa, i-solvent edibeneyo ngamanzi inokongezwa, njengexabiso elincinci le-ethanol.

2. I-Xanthan gum i-polysaccharide ye-anionic, engasetyenziselwa kunye nezinye izinto ze-anionic okanye ezingekho i-ionic, kodwa ayikwazi ukuhambelana nezinto ze-cationic.Isisombululo sayo sinokuhambelana kakuhle kunye nokuzinza kwiityuwa ezininzi.Ukongeza i-electrolytes efana ne-sodium chloride kunye ne-potassium chloride inokuphucula i-viscosity yayo kunye nokuzinza.I-calcium, i-magnesium kunye nezinye iityuwa ze-bivalent zibonise iziphumo ezifanayo kwi-viscosity yazo.Xa i-concentration yetyuwa iphezulu kune-0.1%, i-viscosity efanelekileyo ifikeleleke.Ityuwa ephezulu kakhulu ayiphuculi ukuzinza kwesisombululo se-xanthan gum, kwaye ayichaphazeli i-rheology yayo, kuphela i-pH> Nge-10 o 'clock (imveliso yokutya ayifane ibonakale), i-salts ye-bivalent yensimbi ibonisa ukuthambekela ukwenza iigels.Ngaphantsi kweemeko ze-acidic okanye ezingathathi hlangothi, iityuwa zayo zetsimbi ezine-trivalent ezifana ne-aluminium okanye i-iron form gels.Umxholo ophezulu weetyuwa zetsimbi ze-monovalent zithintela i-gelation.

3. I-Xanthan gum inokudibaniswa kunye ne-thickeners ezininzi zentengiso, ezifana ne-cellulose derivatives, isitashi, i-pectin, i-dextrin, i-alginate, i-carrageenan, njl. Xa idibaniswe ne-galactomannan, inefuthe le-synergistic ekunyuseni i-viscosity.

Ekugqibeleni, i-xanthan gum iyamangalisa ngokwenene yesayensi yanamhlanje.Izakhono zayo ezizodwa njenge-arhente etyebisayo, i-agent yokunqunyanyiswa, i-emulsifier, kunye ne-stabilizer iye yaguqula indlela amashishini ahlukeneyo asebenza ngayo.Ukusuka ekutyeni esikutyayo ukuya kumayeza esithembele kuwo, impembelelo ye-xanthan gum ayinakuphikiswa.Ukuthandwa kwayo kwezorhwebo kunye nokusetyenziswa okubanzi kuyenza ibe yindlu yamandla yokwenyani kwihlabathi lezithako.Yamkela umlingo we-xanthan gum kwaye uvule amandla ayo kwiimveliso zakho namhlanje.
