I-Hydroxypropyl starch ether-HPS

1. Igama lekhemikhali: Hydroxypropyl starch ether

2. Igama lesiNgesi: Hydroxypropylisitatshi ether

3. Isishunqulelo sesiNgesi: HPS

4. Ifomula yemolekyuli: C7H15NO3 Ubunzima beMolekyuli: 161.20

5. Indlela yokulungiselela: Isitashi se-Hydroxypropyl sisitatshi esiguqulwe ngokwekhemikhali, esihlanjululwa yi-propylene oxide kunye nesitatshi ukuze sithathe indawo yeqela le-hydroxyl kwisakhiwo se-starch macromolecule ukuba ibe luhlobo lwesitatshi etherified.

6. Iimpawu ezibonakalayo: umgubo omhlophe (ongenambala) kunye ne-fluidity enhle kunye nokunyibilika kakuhle kwamanzi, isisombululo saso samanzi sicacile kwaye singenambala, kwaye sinozinzo oluhle.Izinzile kwi-asidi kunye ne-alkali, ubushushu be-sintering bungaphantsi kunesitatshi somthonyama, kwaye utshintsho lwe-viscosity eshushu kunye nebanda kakhulu izinzile kunesitatshi somthonyama.Ukuxuba ityuwa kunye ne-sucrose ayinayo impembelelo kwi-viscosity.Emva kwe-etherification, zombini ukuzinza kwe-ice-melt kunye nokungafihli kwaphuculwa.

7. Iimpawu zeMichiza: iipropati ze-starch derivatives kunye ne-hydroxypropyl substituents, iyunithi ye-glucose eyenza isitashi inamaqela angama-3 e-hydroxypropyl anokutshintshwa, ngoko ke iimveliso ezinamaqondo ahlukeneyo anokufumaneka.

8. Iimpawu zobuchwephesha Ukubonakala: umgubo omhlophe, kulula ukuthabatha umswakama

Ukunyibilika: Inokunyibilika emanzini kwaye ibe sisisombululo esingafihliyo

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

Ixabiso le-PH (2% isisombululo samanzi): 8-10

9. Injongo

I-1) Kwishishini lokutya le-hydroxypropyl starch, isitashi se-hydroxypropyl singasetyenziswa njenge-agent agent, isitashi se-hydroxypropyl singasetyenziswa njenge-agent yokumisa, kunye ne-hydroxypropyl starch ingasetyenziswa njenge-adhesive.

2) Umzi-mveliso wephepha le-Hydroxypropyl starch: isitatshi se-hydroxypropyl sisetyenziselwa ukulinganisa iphepha ngaphakathi, isitashi se-hydroxypropyl sisetyenziselwa ukulinganisa umphezulu, isitashi se-hydroxypropyl senza i-inki yokushicilela iqaqambe, isitashi se-hydroxypropyl senza iyunifomu, isitashi se-hydroxypropyl Yenza ifilimu igudiswe, ukusetyenziswa kwe-hydroxypropyl kunye ne-hydroxypropyl starch inamandla athile okutsala iinwele.

3) Umzi-mveliso we-Hydroxypropyl starch textile: isitashi se-hydroxypropyl sinokusetyenziswa njengobungakanani be-warp, isitashi se-hydroxypropyl singaphucula ukuxhathisa kwe-abrasion ngexesha lokuluka, isitashi se-hydroxypropyl kunye nokusebenza kakuhle kokuluka, isitashi se-hydroxypropyl kunye nenqanaba eliphezulu lokutshintsha isitashi se-hydroxypropyl Isiseko sokuprinta singasetyenziswa. .

I-4) I-Hydroxypropyl starch industry ye-pharmaceutical industry: Isitashi se-Hydroxypropyl singasetyenziselwa njenge-agent edibeneyo kwiipilisi, kunye ne-hydroxypropyl starch ingasetyenziselwa njenge-agent ye-plasma bulking.

5) Isitashi seHydroxypropyl sizinzisa udonga lomthombo, isitashi se-hydroxypropyl siphucula iimeko ze-wellbore, isitashi se-hydroxypropyl sithintela ukudilika, kunye ne-hydroxypropyl starch flocculates drill cuttings.

I-6) I-Hydroxypropyl starch yemihla ngemihla yoshishino lweekhemikhali: isitashi se-hydroxypropyl sisetyenziswa kwishishini lemichiza yemihla ngemihla kwaye isitashi se-hydroxypropyl sisetyenziswa njenge-binder, i-agent yokumisa kunye ne-thickener kwi-cosmetics okanye i-coatings.

I-7) Isitashi se-Hydroxypropyl Ukongeza, i-hydroxypropyl starch ingasetyenziselwa njenge-binder yezinto zokwakha, i-gelling agent ye-hydroxypropyl starch coatings okanye i-organic liquids, kunye ne-hydroxypropyl starch.

I-8) Ishishini lokutya: Inokusetyenziswa njenge-adhesive, thickener, i-agent yokumisa ukunyusa ukuzinza.
