I-Hydroxypropyl isitashi ether(HPS) iwuhlobo lwesitashi se-ether etholakala emithonjeni yesitashi yemvelo, njengommbila, amazambane, noma isitashi se-tapioca. Isetshenziswa kabanzi embonini yezokwakha njengesengezo ezintweni zokwakha ezahlukahlukene ngenxa yezakhiwo zayo eziyingqayizivele. Nakhu ukubheka indima ye-hydroxypropyl starch ether ekwakheni:

1. Ukugcina Amanzi: I-HPS isebenza njenge-ejenti egcina amanzi ezintweni zokwakha, ezifana nosimende owenziwe usimende, ama-grouts, nemikhiqizo eyenziwe nge-gypsum. Kuyasiza ukuthuthukisa ukusebenza nokuvumelana kwalezi zinto ngokunciphisa ukulahlekelwa kwamanzi ngesikhathi sokuxuba, ukufakwa, kanye nokwelapha. Lesi sikhathi esandisiwe sokugcinwa kwamanzi sivumela ukugeleza okungcono kwama-binders usimende, okuholela ekuthuthukisweni kokuthuthukiswa kwamandla nokuqina komkhiqizo wokugcina.
2. Ukusebenza Okuthuthukisiwe: I-HPS ithuthukisa ukusebenza kanye nezici zokuphatha zezinto zokwakha. Ngokwandisa ukubumbana kanye nepulasitiki yezingxube zikasimende, kwenza kube lula ukuxutshwa, ukupompa, kanye nokusetshenziswa kodaka nama-grouts. Lokhu kusebenza okuthuthukisiwe kuvumela ukuqedwa okushelelayo kwendawo kanye nokubekwa okunembe kakhudlwana kwezinto zokwakha.
3. Ukunamathela Okuthuthukisiwe: I-HPS ingathuthukisa ukunamathela phakathi kwezinto zokwakha nama-substrates. Uma ingezwe ezintweni ezinamathelayo zamathayili, ama-renders, noma ama-plaster coatings, ithuthukisa ukuhlangana okungcono ezindaweni ezihlukahlukene, okuhlanganisa ukhonkolo, amatshe, amapulangwe, namabhodi e-gypsum. Ukunamathela okuthuthukisiwe kuqinisekisa isibopho esiqinile nesihlala isikhathi eside, kunciphisa ubungozi be-delamination noma ukwehluleka ngokuhamba kwesikhathi.
4. Ukuncipha Nokuwohloka Okuncishisiwe: I-HPS isebenza njengesilungisi se-rheology, esiza ukulawula ukugeleza nokuvumelana kwezinto zokwakha. Ngokunikeza ukuziphatha kokunciphisa i-shear, kunciphisa ukuwohloka nokuwohloka ezinhlelweni zokusebenza ezima mpo noma ngaphezulu, njengokufakwa kwamathayela, amarender, nama-stucco coatings. Le mpahla ye-thixotropic iqinisekisa ukuzinza okungcono kwe-dimensional futhi ivimbela ukuguga ngesikhathi sokufaka isicelo kanye nokwelapha.
5. I-Crack Prevention: I-HPS ingaba negalelo ekwehliseni izigameko zokuqhekeka kwezinto zikasimende. Ngokuthuthukisa ukubumbana namandla aqinile odaka nezingxube zikakhonkolo, kusiza ukunciphisa ukuqhekeka kokuncipha kanye nokulimala kwendawo. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza lapho ubuqotho besakhiwo nokuqina kubaluleke kakhulu, njengalapho kulungiswa khona ukhonkolo kanye nokuqedwa kokuhlobisa.
6. Ukuhambisana Nezithasiselo: I-HPS ihambisana nohlu olubanzi lwezinye izithasiselo ezivame ukusetshenziswa ezintweni zokwakha, njengama-ejenti afaka umoya, ama-plasticizers, kanye nezixube zamaminerali. Ingafakwa kalula ekwakhiweni ngaphandle kokuthikameze kabi ukusebenza noma izakhiwo zezinye izingxenye, iqinisekise ukwakheka kokuzinza nokuvumelana.
7. Ukusimama Kwemvelo: I-HPS isuselwa emithonjeni yesitashi evuselelekayo nebolayo, okuyenza ibe ukukhetha okuvumela imvelo ezinhlelweni zokwakha. Ingasiza ekunciphiseni ukunyathela kwemvelo kwamaphrojekthi wokwakha ngokufaka izithasiselo zokwenziwa nezinye zemvelo.

i-hydroxypropyl starch ether idlala indima ebalulekile ekuthuthukiseni ukusebenza, ukusebenza, nokuqina kwezinto zokwakha. Ukugcinwa kwayo kwamanzi, ukuthuthukiswa kokunamathela, ukulawula i-rheology, kanye nezakhiwo zokuvimbela imifantu kuyenza ibe isengezo esibalulekile ezinhlelweni ezihlukahlukene zokwakha, okunikela kwikhwalithi nokuphila isikhathi eside kwezakhiwo ezakhiwe.
