Hydroxypropyl starch ether(HPS) bụ ụdị starch ether nke sitere na isi mmalite starch eke, dị ka ọka, nduku, ma ọ bụ tapioca starch.A na-ejikarị ya eme ihe na ụlọ ọrụ ihe owuwu dị ka ihe mgbakwunye na ihe ụlọ dị iche iche n'ihi ihe ndị pụrụ iche ya.Nke a bụ nlele ọrụ hydroxypropyl starch ether na-ewu:

1. Njide mmiri: HPS na-eje ozi dị ka onye na-edobe mmiri n'ime ihe owuwu, dị ka ụrọ simenti, grouts, na ngwaahịa ndị dabeere na gypsum.Ọ na-enyere aka melite arụmọrụ na nkwụsi ike nke ihe ndị a site n'ibelata mmiri na-efunahụ n'oge ngwakọta, ngwa, na ọgwụgwọ.Ogologo oge a na-ejigide mmiri na-enye ohere ka mma hydration nke cementitious binders, na-eme ka mma mmepe ike na anwụ ngwa ngwa nke ikpeazụ ngwaahịa.
2. Nrụ ọrụ emelitere: HPS na-eme ka arụ ọrụ na njikwa ihe eji arụ ọrụ dị mma.Site n'ịbawanye ịdị n'otu na plasticity nke ngwakọta cimentious, ọ na-eme ka ọ dị mfe ịgwakọta, mgbapụta, na ngwa ngwa ngwa na grouts.Nke a emelitere ịrụ ọrụ na-enyere aka ịrụcha elu ala dị nro yana idobe ihe eji arụ ọrụ nke ọma.
3. Nkwado emelitere: HPS nwere ike welie njikọ dị n'etiti ihe owuwu na ihe eji arụ ọrụ.Mgbe a na-agbakwunye ya na ihe mkpuchi tile, renders, ma ọ bụ plasta, ọ na-akwalite njikọ dị mma na elu dị iche iche, gụnyere kọmpụta, masonry, wood, na gypsum board.Nkwado dị mma na-eme ka njikọ siri ike ma na-adịgide adịgide, na-ebelata ihe ize ndụ nke delamination ma ọ bụ ọdịda ka oge na-aga.
4. Mbelata Sagging na Slump: HPS na-arụ ọrụ dị ka rheology modifier, na-enyere aka ịchịkwa ọsọ na agbanwe agbanwe nke ihe owuwu.Site n'ịkwalite omume ịhịa aka n'ahụ, ọ na-ebelata mbelata na mkpọda na ngwa kwụ ọtọ ma ọ bụ n'elu, dị ka nrụnye tile, ihe nrụnye, na mkpuchi stucco.Ngwongwo thixotropic a na-eme ka nkwụsi ike nke akụkụ dị mma ma gbochie nrụrụ n'oge ngwa na ọgwụgwọ.
5. Mgbochi mgbawa: HPS nwere ike inye aka na mbenata ihe mgbawa na ihe simenti.Site n'ịkwalite ịdị n'otu na ike nkwụsị nke ngwa agha na ngwakọta kọnkịtị, ọ na-enyere aka belata mbelata mgbawa na ntụpọ elu.Nke a dị mkpa karịsịa na ngwa ebe nhazi na ịdịte aka dị mkpa, dị ka n'ịrụzi ihe na ihe ịchọ mma.
6. Ndakọrịta na ihe mgbakwunye: HPS dakọtara na ọtụtụ ihe mgbakwunye ndị ọzọ a na-ejikarị eme ihe n'ihe owuwu, dị ka ihe na-eme ka ikuku, plasticizers, na ihe mgbakwunye ịnweta.Enwere ike itinye ya n'ụzọ dị mfe n'ime usoro na-enweghị emetụta arụmọrụ ma ọ bụ ihe onwunwe nke ihe ndị ọzọ, na-eme ka nkwụsi ike na nkwụsi ike.
7. Nkwado gburugburu ebe obibi: A na-enweta HPS site na isi mmalite starch nwere ike imeghari na biodegradable, na-eme ka ọ bụrụ nhọrọ enyi na gburugburu ebe obibi maka ngwa owuwu.Ọ nwere ike inye aka belata akara mgbanaka gburugburu ebe obibi nke ọrụ owuwu site na iji ihe ndị ọzọ eke dochie ihe mgbakwunye sịntetik.

hydroxypropyl starch ether na-arụ ọrụ dị oke mkpa n'ịkwalite arụmọrụ, ịrụ ọrụ, na ịdịte aka nke ihe owuwu.Njide mmiri ya, nkwalite adhesion, njikwa rheology, na ihe mgbochi mgbawa na-eme ka ọ bụrụ ihe mgbakwunye bara uru na ngwa ụlọ dị iche iche, na-enye aka n'ịdị mma na ogologo oge nke ihe ndị e wuru.
