Iipropathi zokulungiselela kunye nezomzimba ze-hydroxypropy starch ether

I-Hydroxypropy i-Starch Ether (i-HPSTE) ilungiselelwe ngenkqubo yokuhlengahlengiswa yekhemikhali ebandakanya ukwazisa amaqela e-hydroxypropy kwimolekyuli yesitatshi. Indlela yokulungiselela iqhele ukubandakanya la manyathelo alandelayo:

1. Isitatshi: isitatshi esikumgangatho ophakathi, sihlala sivela kwimithombo efana nengqolowa, ingqolowa, i-bit, okanye i-pitato, okanye i-tapioca, ikhethwe njengento yokuqalisa. Ukukhetha komthombo wesitatshi kunokuchaphazela iipropathi zemveliso yokugqibela ye-HPSTE.
2. Ukulungiswa kwe-Starch Paste: Isitatshi esikhethiweyo sisasazeka emanzini ukwenza i-starch paste. I-Cola ishushu kubushushu obuthile ukuya e-getiginize i-gonitus yesitayela, ivumela ukuphinda iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde isebenze kumanyathelo alandelayo ohlengahlengiso.
3. Ukuphendula kwe-Etheritition: I-Telaginited Standard Paste iphendulwa kunye ne-propylene oxide (PO) phambi kwemeko entle phantsi kweemeko ezilawulwayo. I-propylene oxide iphikisana namaqela e-hydroxyl (--) kwimolekyuli yesitatshi, okukhokelela ekuncamathisweni kwamaqela e-hydroxypropyl
4. Ukungathathi cala kunye nokucoca: Emva kokuphendula kwe-Etheriya, umxube wokuphendula awunamacala ukususa nayiphi na irejista okanye i-catalysts. I-Hydroxypropy ye-HydroxyPl ye-HydroxyPlapy I-Ether Stanch Ether ihlanjululwe kwiinkqubo ezinje ngokwenzakala, ukuhlamba, kunye nokomisa ukususa ukungcola kunye neekhemikhali ezigqithisileyo.
5. Ubungakanani be-paricle yohlengahlengiso: Iipropathi zomzimba ze-HPSTE, ezinje ngobukhulu obunenxaxheba kunye nokusasazwa, kunokulungiswa kwiinkqubo zokulinganisa okanye ukugaya ukufezekisa iimpawu ezinqwenelekayo zezicelo ezithile.

Iipropathi zomzimba ze-Hydroxypropy i-starch ether ingahluka ngokuxhomekeka kwizinto ezinje ngenqanaba lokufakelwa endaweni ye (DS), ubungakanani bemolekyuli, kunye neemeko ze-molek. Ezinye iipropathi eziqhelekileyo ze-HPSE zibandakanya:

1. Inkangeleko: I-HPSTE iqhele ukuba ibe ngumgubo we-off-off-off-off-whild of Patriclus Isuntswana i-morphology inokwahluka kwi-spherical ukuya kwimilo engaqhelekanga ngokuxhomekeka kwinkqubo yokuphucula.
2. Ubungakanani be-suricle: Ubungakanani be-hpsicle ye-HPSTE bunokuvela kumantshontsho ambalwa ukuya kumashumi eminzi ye-micrometer, ngefuthe elibonakalayo ekusasazeni kwayo, ukuluka nokusebenza kunye nokusebenza kwizicelo ezahlukeneyo.
3. Ukuxinana kobuninzi: Ubuninzi be-bultte ye-HPSTE buxhamla ukuhamba kwayo, ukuphatha iimpawu, kunye neemfuno zokupakisha. Ihlala ilinganiswe kwigram nganye i-cubicter i-cubicter (g / cm³) okanye iikhilogrem ngelitha nganye (kg / l).
4. Ukuluka: I-HPSTE i-insuble emanzini ebandayo kodwa inokusasaza kwaye idumbe amanzi ashushu, yenza izisombululo ze-vills okanye ze-vills. I-smollity kunye neepropathi ze-hydration ye-HPSE zinokwahluka kuxhomekeka kwizinto ezinje nge-DS, ubunzima bemolekyuli, kunye nobushushu.
5. I-Viskosity: I-HPSTE IPRTUPSIRS TICKIT kunye nePROOLOTERITER KWIINGXAKI ZEEMPAHLA, Ephethe i-viscosity, indlela yokuhamba yokuhamba, kunye nokuzimela kwezinto ezenziwayo. Uhlobo lwezisombululo ze-HPSTE luxhomekeke kwizinto ezinje ngoxinzelelo, ubushushu, kunye nenqanaba le-Shear.
6. I-hydration Inqanaba: Inqanaba le-hydration ye-HPSTE libhekisa kwinqanaba apho lifunxa amanzi kunye nokudumba ukwenza izisombululo ze-viscous okanye iigesi. Le ndawo ibalulekile kwizicelo apho kufuna ukuhamba ngokukhawuleza kwe-hydding kunye nokutyibilika.

Iipropathi zokulungiselela kunye nezomzimba ze-hydroxypropy i-starch ether zilungiselelwe ukufezekisa iimfuno ezithile zesicelo kunye neendlela zokusebenza, zenza ukuba zibe yindawo yokusebenza kunye nezongezo ezixabisekileyo kwimizi-mveliso eyahlukeneyo kunye nefomu.
