Hydroxypropyl hmoov txhuv nplej siab ether-HPS

1. Tshuaj npe: Hydroxypropyl starch ether

2. Lub npe Askiv: Hydroxypropylhmoov nplej ether

3. Lus Askiv luv: HPS

4. Molecular mis: C7H15NO3 Molecular mass: 161.20

5. Txoj kev npaj: Hydroxypropyl hmoov txhuv nplej siab yog cov hmoov txhuv nplej siab hloov kho, uas yog etherified los ntawm propylene oxide thiab hmoov txhuv nplej siab los hloov cov pawg hydroxyl hauv cov hmoov txhuv nplej siab macromolecule los ua ib hom etherified starch.

6. Lub cev muaj zog: dawb (xim tsis muaj xim) hmoov nrog zoo fluidity thiab zoo solubility ntawm dej, nws cov kua aqueous yog pob tshab thiab tsis muaj xim, thiab muaj kev ruaj ntseg zoo.Nws ruaj khov rau cov kua qaub thiab alkali, qhov kub ntawm sintering yog qis dua li cov hmoov txhuv nplej siab, thiab qhov kev hloov ntawm kub thiab txias viscosity yog ruaj khov dua li cov hmoov txhuv nplej siab.Kev sib xyaw nrog ntsev thiab sucrose tsis cuam tshuam rau viscosity.Tom qab etherification, ob qho tib si dej khov-melt stability thiab pob tshab tau txhim kho.

7. Chemical zog: cov khoom ntawm starch derivatives nrog hydroxypropyl substituents, cov piam thaj unit constituting starch muaj 3 hydroxypropyl pawg uas yuav tsum tau hloov, yog li cov khoom uas muaj ntau degrees ntawm kev hloov tau.

8. Kev ntsuas qhov tshwm sim: hmoov dawb, yooj yim nqus dej

Solubility: tuaj yeem yaj hauv dej thiab dhau los ua cov tshuaj pob tshab

viscosity (5% aqueous tov, 20℃Ua haujlwm siab: 500-20000 mPa

PH tus nqi (2% aqueous tov): 8-10

9. Lub hom phiaj

2) Hydroxypropyl starch daim ntawv kev lag luam: hydroxypropyl starch yog siv rau sab hauv sizing ntawm daim ntawv, hydroxypropyl starch yog siv rau nto sizing, hydroxypropyl starch ua luam number case ci, hydroxypropyl starch ua rau uniform, hydroxypropyl starch ua rau cov zaj duab xis du, hydroxypropyl starch txo tus number case noj, thiab hydroxypropyl hmoov txhuv nplej siab muaj peev xwm rub cov plaub hau.

3) Hydroxypropyl starch textile kev lag luam: hydroxypropyl starch yuav siv tau raws li warp loj, hydroxypropyl starch tuaj yeem txhim kho kev puas tsuaj thaum lub sij hawm xaws, hydroxypropyl starch thiab weaving efficiency, hydroxypropyl starch nrog high degree ntawm kev hloov ntawm hydroxypropyl starch Base starch yuav siv tau raws li luam ntawv paste. .

4) Hydroxypropyl starch kev lag luam kws tshuaj: Hydroxypropyl starch tuaj yeem siv los ua tus neeg sawv cev rau cov ntsiav tshuaj, thiab hydroxypropyl hmoov txhuv nplej siab kuj tuaj yeem siv los ua cov tshuaj plasma bulking.

5) Hydroxypropyl starch stabilizes lub phab ntsa zoo, hydroxypropyl hmoov txhuv nplej siab txhim kho cov kab mob zoo, hydroxypropyl starch tiv thaiv kev tawg, thiab hydroxypropyl starch flocculates xyaum txiav.

6) Hydroxypropyl hmoov txhuv nplej siab txhua hnub kev lag luam tshuaj: hydroxypropyl hmoov txhuv nplej siab yog siv nyob rau hauv kev lag luam tshuaj txhua hnub thiab hydroxypropyl starch yog siv los ua binder, suspending agent thiab thickener hauv tshuaj pleev ib ce lossis coatings.

7) Hydroxypropyl starch Tsis tas li ntawd, hydroxypropyl starch kuj tseem siv tau los ua cov khoom siv hauv tsev, ib tus neeg sawv cev rau hydroxypropyl starch coatings los yog kua organic, thiab hydroxypropyl starch.

8) Kev lag luam khoom noj khoom haus: Nws tuaj yeem siv los ua cov nplaum, thickener, tshem tawm tus neeg sawv cev kom muaj kev ruaj ntseg.
