Hydroxypropyl starch ether maka owuwu

Hydroxypropyl Starch Ether (HPS) bụ ngwaahịa starch emezigharịrị nke a na-eji n'ụlọ ọrụ ihe owuwu dị ka ihe na-agbapụta, ihe nkedo, na onye na-ejigide mmiri. A na-eme HPS site n'ịgwọ starch ọka na otu hydroxypropyl, nke na-enye ya ihe pụrụ iche na-eme ka ọ baa uru na ngwa ihe owuwu dị iche iche.

Otu n'ime isi ngwa nke HPS na-ewu bụ dị ka thickener. HPS nwere ihe ndị na-agbapụta nke ọma na enwere ike iji mee ka viscosity nke nkwusioru mmiri, dị ka agba, adhesives, na ngwa agha. Nke a ka mma viscosity nwere ike inye aka melite arụmọrụ na mgbasa nke ngwaahịa ndị a, na-eme ka ọ dị mfe itinye na iji.

A na-ejikwa HPS dịka ihe eji arụ ọrụ. Ọ nwere ike inye aka melite ike njikọta nke ihe, dị ka ngwa agha, nrapado, na grouts. Nke a na-eme ka ike na-ejikọta ọnụ na-eme ka ọ dịkwuo mma nwere ike inye aka melite arụmọrụ nke ngwaahịa ndị a n'ozuzu ya, na-eme ka ha dịkwuo ogologo ma na-eguzogide mgbawa, nkwụsị, na ụdị mmebi ndị ọzọ.

A na-ejikwa HPS dị ka ihe na-ejigide mmiri na-ewu ụlọ. Ọ nwere ike inye aka melite njigide mmiri nke ngwa agha, adhesives, na grouts, na-enyere aka melite ọrụ ha na arụmọrụ zuru ezu.
