I-Hydroxypropyl isitashi ether-HPS

1. Igama lekhemikhali: I-Hydroxypropyl isitashi ether

2. Igama lesiNgisi: Hydroxypropylisitashi ether

3. Isifinyezo sesiNgisi: HPS

4. Ifomula ye-molecular: C7H15NO3 Isisindo se-Molecular: 161.20

5. Indlela yokulungiselela: I-Hydroxypropyl isitashi isitashi esiguquliwe ngamakhemikhali, esifakwa etherified nge-propylene oxide nesitashi ukuze sithathele indawo yeqembu le-hydroxyl esakhiweni se-starch macromolecule ukuze sibe uhlobo lwesitashi etherified.

6. Izinto ezibonakalayo: impushana emhlophe (engenambala) ene-fluidity enhle nokuncibilika kahle kwamanzi, isixazululo sayo samanzi sisobala futhi asinambala, futhi sinokuzinza okuhle.Iqinile ibe yi-asidi ne-alkali, izinga lokushisa le-sintering liphansi kunesitashi somdabu, futhi ukuguqulwa kwe-viscosity eshisayo nebandayo kuzinze kakhulu kunesitashi somdabu.Ukuxuba nosawoti kanye ne-sucrose akunawo umthelela ku-viscosity.Ngemuva kokufakwa kwe-etherification, kokubili ukuzinza kweqhwa nokuncibilika kwathuthukiswa.

7. Izakhiwo zamakhemikhali: izakhiwo ze-starch derivatives ezine-hydroxypropyl substituents, iyunithi ye-glucose eyakha isitashi inamaqembu angu-3 e-hydroxypropyl angashintshwa, ngakho imikhiqizo enamazinga ahlukene okushintsha ingatholakala.

8. Izinkomba zobuchwepheshe Ukubukeka: impushana emhlophe, kulula ukumunca umswakama

I-Solubility: Ingancibilika emanzini futhi ibe isixazululo esisobala

I-Viscosity (5% isixazululo samanzi, 20℃): 500-20000 mPa.s

Inani le-PH (2% isixazululo esinamanzi): 8-10

9. Injongo

I-1) Embonini yokudla ye-hydroxypropyl isitashi, isitashi se-hydroxypropyl singasetshenziswa njenge-ejenti yokuqina, isitashi se-hydroxypropyl singasetshenziswa njenge-ejenti yokumisa, kanti isitashi se-hydroxypropyl singasetshenziswa njenge-adhesive.

2) Imboni yephepha le-Hydroxypropyl starch: isitashi se-hydroxypropyl sisetshenziselwa ukulinganisa kwangaphakathi kwephepha, isitashi se-hydroxypropyl sisetshenziselwa ukulinganisa indawo, isitashi se-hydroxypropyl senza inki yokuphrinta ikhanye, isitashi se-hydroxypropyl senza umfaniswano, isitashi se-hydroxypropyl Yenza ifilimu ibushelelezi, ukusetshenziswa kwe-hydroxypropyl kunciphisa isitashi futhi isitashi se-hydroxypropyl sinekhono elithile lokudonsa izinwele.

I-3) Imboni yendwangu ye-Hydroxypropyl isitashi: isitashi se-hydroxypropyl singasetshenziswa njengosayizi we-warp, isitashi se-hydroxypropyl singathuthukisa ukumelana ne-abrasion ngesikhathi sokweluka, isitashi se-hydroxypropyl nokusebenza kahle kokweluka, isitashi se-hydroxypropyl ngezinga eliphezulu lokufaka esikhundleni se-hydroxypropyl isitashi sesisekelo singasetshenziswa .

I-4) Imboni yezemithi ye-Hydroxypropyl isitashi: Isitashi se-Hydroxypropyl singasetshenziswa njenge-ejenti ehlukanisayo yamaphilisi, futhi isitashi se-hydroxypropyl singasetshenziswa njenge-ejenti ye-plasma bulking.

5) Isitashi seHydroxypropyl sisimamisa udonga lomthombo, isitashi se-hydroxypropyl sithuthukisa izimo ze-wellbore, isitashi se-hydroxypropyl sivimbela ukuwohloka, futhi isitashi se-hydroxypropyl sigeleza ukusikwa kokubhola.

I-6) I-Hydroxypropyl starch yansuku zonke yamakhemikhali embonini: isitashi se-hydroxypropyl sisetshenziswa embonini yamakhemikhali yansuku zonke futhi isitashi se-hydroxypropyl sisetshenziswa njenge-binder, i-ejenti yokumisa okwesikhashana kanye ne-thickener kuzimonyo noma ezimbotsheni.

I-7) I-Hydroxypropyl isitashi Ngaphezu kwalokho, isitashi se-hydroxypropyl singasetshenziswa futhi njengesibophezelo sezinto zokwakha, i-ejenti ye-gelling ye-hydroxypropyl starch coatings noma uketshezi oluphilayo, kanye nesitashi se-hydroxypropyl.

I-8) Imboni yokudla: Ingasetshenziswa njenge-adhesive, thickener, i-ejenti yokumisa ukukhulisa ukuzinza.
