Hydroxypropyl starch ether(HPS) luhlobo lwe-ether yestatshi ephuma kwimithombo yendalo yesitatshi, njengombona, iitapile, okanye isitatshi setapioca. Isetyenziswa ngokubanzi kwishishini lokwakha njengesongezo kwizinto ezahlukeneyo zokwakha ngenxa yeempawu zayo ezizodwa. Nantsi ukujonga indima ye-hydroxypropyl starch ether kulwakhiwo:

1. Ukugcina Amanzi: I-HPS isebenza njengesixhobo sokugcina amanzi kwizinto zokwakha, ezifana nodaka olusekwe kwisamente, iigrouts, kunye neemveliso ezenziwe ngegypsum. Inceda ukuphucula ukusebenza kunye nokuhambelana kwezi zixhobo ngokunciphisa ukulahlekelwa kwamanzi ngexesha lokuxuba, ukusetyenziswa kunye nokunyanga. Eli xesha lokugcinwa kwamanzi elongeziweyo livumela ukuhanjiswa okungcono kwe-cementitious binders, okukhokelela kuphuhliso oluphuculweyo lwamandla kunye nokuqina kwemveliso yokugqibela.
2. Ukomelezwa kokuSebenza: I-HPS iphucula ukusebenza kunye neempawu zokuphatha izinto zokwakha. Ngokwandisa ubumbano kunye neplastiki yemixube ye-cementitious, iququzelela ukuxuba okulula, ukupompa, kunye nokusetyenziswa kodaka kunye ne-grouts. Oku kusebenza kwandisiweyo kwenza ukuba umphezulu ugqitywe kakuhle kunye nokubekwa okuchane ngakumbi kwezinto zokwakha.
3. Ukubambelela okuphuculweyo: I-HPS inokuphucula ukubambelela phakathi kwezinto zokwakha kunye ne-substrates. Xa idityaniswe kwizinto zokuncamathelisa iithayile, unikezelo, okanye udaka lokutyabeka, ikhuthaza ukudibanisa okungcono kwiindawo ezahlukeneyo, kubandakanywa ikhonkrithi, i-masonry, iplanga kunye neebhodi zegypsum. Ukubambelela okuphuculweyo kuqinisekisa ibhondi eyomeleleyo kunye neyomeleleyo, ukunciphisa umngcipheko we-delamination okanye ukungaphumeleli ekuhambeni kwexesha.
4. Ukunciphisa i-Sagging kunye ne-Slump: I-HPS isebenza njenge-rheology modifier, inceda ukulawula ukuhamba kunye nokuhambelana kwezinto zokwakha. Ngokunikezela ngokuziphatha kokucheba, kunciphisa ukuthoba kunye nokudilika kwizicelo ezithe nkqo okanye ngaphezulu, ezinje ngofakelo lweethayile, unikezelo, kunye nokwaleka kwe-stucco. Le propati ye-thixotropic iqinisekisa ukuzinza okungcono kwe-dimensional kunye nokuthintela ukuguqulwa ngexesha lokusetyenziswa kunye nokunyanga.
5. Uthintelo lwe-Crack: I-HPS inokuba negalelo ekunciphiseni iziganeko zokuqhekeka kwezinto zesamente. Ngokwandisa ubumbano kunye namandla okuqina odaka kunye nemixube yekhonkrithi, inceda ukunciphisa ukuqhekeka kwe-shrinkage kunye neziphene zomhlaba. Oku kubaluleke kakhulu kwizicelo apho ukuthembeka kwesakhiwo kunye nokuqina kubaluleke kakhulu, njengokulungiswa kwekhonkrithi kunye nokugqitywa kokuhlobisa.
6. Ukuhambelana neZongezo: I-HPS iyahambelana noluhlu olubanzi lwezinye izongezo ezisetyenziswa ngokuqhelekileyo kwizinto zokwakha, ezifana ne-air-entraining agents, i-plasticizers, kunye ne-mineral admixtures. Inokuthi ifakwe ngokulula kwimiqulu ngaphandle kokuchaphazela kakubi ukusebenza okanye iimpawu zamanye amacandelo, ukuqinisekisa ukuzinza kunye nokuhambelana.
7. Uzinzo lokusiNgqongileyo: I-HPS ithathwe kwimithombo yesitatshi ehlaziyekayo nenokonakala, iyenza ibe lukhetho olulungele ukusingqongileyo kwizicelo zokwakha. Inokunceda ukunciphisa ubume bemeko yendawo yeeprojekthi zokwakha ngokususa izongezo ezenziweyo kunye nezinye zendalo.

i-hydroxypropyl starch ether idlala indima ebalulekileyo ekuphuculeni ukusebenza, ukusebenza, kunye nokuqina kwezinto zokwakha. Ukugcinwa kwayo kwamanzi, ukuphuculwa kokubambelela, ukulawula i-rheology, kunye neempawu zokuthintela ukuqhekeka kwenza ukuba ibe yinto eyongezelelweyo exabisekileyo kwizicelo ezahlukeneyo zokwakha, igalelo kumgangatho kunye nokuphila ixesha elide kwezakhiwo ezakhiweyo.
