Yintoni iHydroxypropyl Guar Gum?

1.1 Inkcazelo esisiseko yeHydroxypropyl Guar Gum

I-Hydroxypropyl guar gum, ekwaziwa ngokuba yi-HPG, yi-polymer engenakunyibilika emanzini efunyanwa ngokuguqulwa kweekhemikhali kwe-guar gum yendalo. I-Guar gum yi-polysaccharide yendalo ekhutshwe kwi-endosperm yeembotyi ze-guar (eveliswa kakhulu eIndiya nasePakistan), eyenziwe ziiyunithi ze-galactose kunye ne-mannose ezidityaniswe ziibhondi ze-glycosidic. Nangona kunjalo, i-natural guar gum inemida ethile ekusetyenzisweni kwayo, njengokunyibilika okungafanelekileyo emanzini abandayo, ukubola lula phantsi kweemeko zobushushu obuphezulu kunye ne-acid-base, kunye nokuzinza okungonelanga kwe-viscosity. Ngokusebenzisa utshintsho lwe-hydroxypropylation, ulwakhiwo lwe-molecular ye-guar gum luyaphuculwa, olulungisa iziphene ze-natural guar gum kwaye luphucula ukusebenza kwayo kunye nobubanzi bayo.

Ngokungafaniyo ne-guar gum yendalo, i-hydroxypropyl guar gum ineqela le-hydroxypropyl elifakwe kwi-molecular chain yayo, enciphisa ukusebenzisana kwe-hydrogen bond phakathi kwee-molecules, iphucula ukunyibilika kwayo kunye nozinzo, kwaye iyenza ihambelane ngcono nezinye izongezo. Ivezwa njengomgubo omhlophe ukuya komdaka okhanyayo omdaka, ongenavumba phantse, kwaye inokusasazwa ngokukhawuleza emanzini ashushu okanye abandayo ukuze yenze isisombululo esiqinileyo, esisetyenziswa kakhulu kwiindawo ezahlukeneyo zoshishino njengesithako esisebenzayo. Xa kuthelekiswa nezinye iimveliso ze-guar gum eziguquliweyo, i-HPG inomsebenzi ogqwesileyo obanzi, okwenza ukuba ibe lukhetho olukhethwayo kumashishini amaninzi kwimveliso yezimboni yehlabathi.

1.2 Umgaqo-nkqubo weMveliso kunye neNkqubo yeHydroxypropyl Guar Gum

Ukuveliswa kwe-hydroxypropyl guar gum ikakhulu kuthatha iimbotyi ze-guar ezikumgangatho ophezulu njengezinto eziluhlaza, kwaye kudlula kwiinkqubo ezahlukeneyo ezifana nokucoca, ukuxobula, ukususa iintsholongwane, ukutyumza, ukuhluza, ukuguqulwa kwe-hydroxypropylation, ukuthamba, ukuhlamba, ukomisa, kunye nokutyumza. Inyathelo eliphambili yindlela yokuguqula i-hydroxypropylation, edla ngokwenziwa phantsi kweemeko ze-alkaline kunye ne-propylene oxide njenge-etherifying agent.

Ngokukodwa, umgubo we-guar gum ocutshungulweyo uqala unyibilikiswe kumanzi afanelekileyo ukuze wenze isisombululo esithambileyo, uze emva koko kongezwe i-alkaline catalyst (efana ne-sodium hydroxide) ukuze kusebenze amaqela e-hydroxyl kwi-guar gum molecular chain. Emva koko, i-propylene oxide yongezwa kancinci phantsi kweemeko zobushushu ezilawulwayo kunye noxinzelelo, kwaye amaqela e-hydroxyl kwi-guar gum molecular chain asabela kunye ne-propylene oxide ukuze angenise amaqela e-hydroxypropyl kwisakhiwo se-molecular. Emva kokuba i-reaction igqityiwe, imveliso iyasuswa kwi-neutral nge-asidi (efana ne-hydrochloric acid), ihlanjwe ukuze kususwe ukungcola kunye nezinto ezingasetyenziswanga, yomiswe ibe ngumxholo othile womswakama, kwaye ekugqibeleni ichotshozwe kwaye ihluzwe ukuze kufunyanwe imveliso ye-hydroxypropyl guar gum egqityiweyo.

Iimpawu eziphambili zeHydroxypropyl Guar Gum

I-Hydroxypropyl guar gum ineempawu ezahlukeneyo ezibalaseleyo, ezivela kwisakhiwo sayo se-molecular esiguquliweyo. Xa ithelekiswa ne-natural guar gum kunye nezinye izinto ezifanayo zokutyeba, ineenzuzo ezicacileyo zokunyibilika, ukuzinza, ukuhambelana, kunye nezinye izinto, ezenza ukuba ivelele kwimarike yezongezo ezisebenzayo zehlabathi. Ezi zilandelayo ziimpawu eziphambili zeemveliso zethu ze-hydroxypropyl guar gum:

2.1 Ukunyibilika Okugqwesileyo kunye nesantya sokunyibilika esikhawulezayo

Enye yezona nzuzo zinkulu ze-hydroxypropyl guar gum kukunyibilika kwayo okuhle kakhulu. I-guar gum yendalo kunzima ukuyinyibilikisa emanzini abandayo, idla ngokufuna ukufudunyezwa ukuze inyibilike, kwaye ithambekele ekwenzeni ii-agglomerates, nto leyo echaphazela isiphumo sokusetyenziswa. Nangona kunjalo, emva kokuguqulwa kwe-hydroxypropylation, i-hydrophilicity ye-hydroxypropyl guar gum iphucuka kakhulu, kwaye inokusasazeka ngokukhawuleza kwaye inyibilike emanzini abandayo nasemanzini ashushu ngaphandle kokufudumeza, kwaye akukho zi-agglomerates ziya kwenziwa, nto leyo ephucula kakhulu ukusebenza kakuhle kunye nokulula kokusetyenziswa.

Ngokubanzi, i-hydroxypropyl guar gum inokwenza isisombululo esifana nesiqinileyo ngaphakathi kwemizuzu eli-10-20 xa yongezwa emanzini abandayo, kwaye isantya sokunyibilika sinokukhawuleziswa ngakumbi emanzini ashushu. Isisombululo sayo samanzi se-1% sinoburhabaxa obumalunga ne-3000mPa·S, kwaye uburhabaxa bunokulungiswa ngokwesixa esongeziweyo, esifanelekileyo kwiimeko ezahlukeneyo zokusetyenziswa. Olu phawu lwenza i-HPG yonge ixesha elininzi kunye neendleko kwinkqubo yemveliso, kwaye ithandwa kakhulu ngamashishini akwimizi-mveliso eyahlukeneyo.

2.2 Ukuqina Okuzinzileyo Nokumelana Okunamandla Nezinto Zangaphandle

I-Hydroxypropyl guar gum inozinzo oluhle kakhulu lwe-viscosity, kwaye i-viscosity yayo ayilula ukuyitshintsha phantsi kwempembelelo yobushushu, ixabiso le-pH, i-electrolyte, kunye nezinye izinto zangaphandle, nto leyo engcono kakhulu kune-natural guar gum. Ngokukodwa, i-viscosity yayo ihlala izinzile kuluhlu lwe-pH oluyi-3.5-10, kwaye iyancipha kakhulu xa ixabiso le-pH liphezulu kune-10 okanye ngaphantsi kwe-3.5; kuluhlu lobushushu oluyi-0-150℃, isenokugcina ukusebenza kakuhle kwe-viscosity, kwaye akukho lula ukuyithoba nokulahlekelwa yi-viscosity kubushushu obuphezulu, efanelekileyo kwitekhnoloji yokucubungula ubushushu obuphezulu.

Ukongeza, i-hydroxypropyl guar gum inokumelana okukhulu kwe-electrolyte. Nokuba kukho ii-ion zesinyithi (ezifana nee-ion ze-sodium, ii-ion ze-calcium), i-viscosity yayo ayitshintshi kakhulu, nto leyo eyenza ukuba isetyenziswe kwiinkqubo ezahlukeneyo eziqulethe ii-electrolytes, ezifana nokutya, izinto zokuthambisa, ulwelo lokubhola i-oyile, kunye nezinye iindawo, nto leyo eyandisa umda wokusetyenziswa kwayo. Xa kuthelekiswa ne-xanthan gum, enye into eqhelekileyo etyebisayo, i-HPG inozinzo olungcono lwe-viscosity phantsi kobushushu obuphezulu kunye neemeko ezinamandla ze-alkali, enezibonelelo ezingaphezulu kwezinye iindawo ezikhethekileyo zoshishino.
