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 ihe, 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.
