Hydroxypropyl starch ether-HPS

1. Zita remakemikari: Hydroxypropyl starch ether

2. Zita reChirungu: Hydroxypropylstarch ether

3. Muchidimbu Chirungu: HPS

4. Molecular formula: C7H15NO3 Molecular mass: 161.20

5. Kugadzirira nzira: Hydroxypropyl starch is chemically modified starch, iyo inogadziriswa nepropylene oxide uye starch kutsiva boka re hydroxyl mu starch macromolecule maitiro kuti ave rudzi rwe etherified starch.

6. Zvimiro zvemuviri: chena (isina ruvara) poda ine mvura yakanaka uye yakanaka kunyungudika kwemvura, mhinduro yayo yemvura inopenya uye isina ruvara, uye ine kugadzikana kwakanaka. Yakagadzikana kune asidhi uye alkali, tembiricha yekupisa yakadzikira pane yekuzvarwa starch, uye shanduko yekupisa uye inotonhora viscosity yakagadzikana kupfuura iyo yekuzvarwa starch. Kusanganiswa nemunyu uye sucrose hakuna simba pane viscosity. Mushure me etherification, zvose ice-melt kugadzikana uye kujeka kwakavandudzwa.

7. Chemical properties: zvinhu zve starch derivatives ne hydroxypropyl substituents, glucose unit inoumba starch ine 3 hydroxypropyl mapoka anogona kutsiviwa, saka zvigadzirwa zvine madhigirii akasiyana-siyana anogona kuwanikwa.

8. Technical zviratidzo Kuonekwa: chena poda, nyore kutora unyoro

Solubility: Inogona kunyungudika mumvura uye kuva mhinduro yakajeka

Viscosity (5% aqueous solution, 20℃): 500-20000 mPa.s

PH kukosha (2% aqueous solution): 8-10

9. Chinangwa

1) Muindasitiri yekudya yehydroxypropyl starch, hydroxypropyl starch inogona kushandiswa seyakakora mumiriri, hydroxypropyl starch inogona kushandiswa seanomisa mumiriri, uye hydroxypropyl starch inogona kushandiswa seanonamira.

2) Hydroxypropyl starch bepa indasitiri: hydroxypropyl starch inoshandiswa kuyera mukati mebepa, hydroxypropyl starch inoshandiswa kuita saizi yepasi, hydroxypropyl starch inoita inki yekudhinda kupenya, hydroxypropyl starch inoita yunifomu, hydroxypropyl starch Itai kuti firimu rive rakatsetseka, hydroxypropyl kushandisa starch, inoderedza mushishi. uye hydroxypropyl starch ine kumwe kugona kudhonza bvudzi.

3) Hydroxypropyl starch textile industry: hydroxypropyl starch inogona kushandiswa sewarp size, hydroxypropyl starch inogona kuvandudza abrasion resistance panguva yekurukwa, hydroxypropyl starch uye kuruka zvakanaka, hydroxypropyl starch ine high degree yekutsiva hydroxypropyl starch Base starch inogona kushandiswa .

4) Hydroxypropyl starch mishonga yemishonga: Hydroxypropyl starch inogona kushandiswa sechinhu chinoparadza pamapiritsi, uye hydroxypropyl starch inogonawo kushandiswa seplasma bulking agent.

5) Hydroxypropyl starch inodzikamisa madziro emutsime, hydroxypropyl starch inovandudza matsime emvura, hydroxypropyl starch inodzivirira kudonha, uye hydroxypropyl starch flocculates drill cuttings.

6) Hydroxypropyl starch zuva rega rega kemikari indasitiri: hydroxypropyl starch inoshandiswa muindasitiri yemakemikari yemazuva ese uye hydroxypropyl starch inoshandiswa sebinder, inomisa agent uye thickener muzvizoro kana machira.

7) Hydroxypropyl starch Mukuwedzera, hydroxypropyl starch inogonawo kushandiswa sebhainda rekuvaka zvinhu, gelling agent ye hydroxypropyl starch coatings kana organic liquids, uye hydroxypropyl starch.

8) Indasitiri yechikafu: Inogona kushandiswa seanonamira, thickener, kumisa mumiririri kuwedzera kugadzikana.
