Hydroxypropyl starch ether(HPS) ke mofuta oa starch ether e nkiloeng mehloling ea tlhaho ea setache, joalo ka poone, litapole, kapa tapioca starch. E sebelisoa haholo indastering ea kaho e le tlatsetso ea thepa e sa tšoaneng ea mohaho ka lebaka la thepa ea eona e ikhethang. Mona ke pono ea karolo ea hydroxypropyl starch ether kahong:

1. Ho Boloka Metsi: HPS e sebetsa e le ntho e bolokang metsi linthong tsa kaho, tse kang lirekere tse entsoeng ka samente, li-grouts le lihlahisoa tse entsoeng ka gypsum. E thusa ho ntlafatsa ts'ebetso le botsitso ba lisebelisoa tsena ka ho fokotsa tahlehelo ea metsi nakong ea ho kopanya, ho sebelisoa le ho phekola. Nako ena e atolositsoeng ea ho boloka metsi e lumella hore ho be le hydration e ntle ea li-binders tsa cementitious, e leng se hlahisang ntlafatso ea matla le ho tšoarella ha sehlahisoa sa ho qetela.
2. Matla a Ntlafetseng: HPS e ntlafatsa ts'ebetso le ho sebetsana le litšobotsi tsa thepa ea kaho. Ka ho eketsa momahano le polasetiki ea metsoako ea cementitious, e nolofatsa ho kopanya, ho pompa le ho sebelisoa ha seretse le li-grouts. Ts'ebetso ena e ntlafalitsoeng e etsa hore ho be bonolo ho qeta bokaholimo le ho bea thepa ea kaho ka nepo haholoanyane.
3. Khomarelo e Ntlafetseng: HPS e ka ntlafatsa ho khomarela pakeng tsa thepa ea kaho le li-substrates. Ha e kenyellelitsoe lithaeleng tsa lithaele, li-renders, kapa lirapeng tsa samente, e khothalletsa maqhama a betere libakeng tse fapaneng, ho kenyeletsoa konkreite, masonry, lehong le gypsum board. Ho ntlafala ho khomarela ho tiisa maqhama a matla le a tšoarellang, ho fokotsa kotsi ea delamination kapa ho hlōleha ha nako e ntse e feta.
4. Ho Fokotsa ho Sagging le ho Slump: HPS e sebetsa joalo ka rheology modifier, e thusa ho laola phallo le botsitso ba thepa ea kaho. Ka ho fana ka boits'oaro ba ho kuta, e fokotsa ho thella le ho putlama lits'ebetsong tse otlolohileng kapa tse holimo, joalo ka ho kenya lithaele, li-renders le likoti tsa stucco. Thepa ena ea thixotropic e tiisa botsitso bo betere ba dimensional mme e thibela deformation nakong ea kopo le ho folisa.
5. Thibelo ea Crack: HPS e ka kenya letsoho ho fokotsa sekhahla sa ho petsoha ha thepa ea samente. Ka ho matlafatsa momahano le matla a thata a metsoako ea seretse le konkreite, e thusa ho fokotsa ho phatloha ho hoholo le ho senyeha ha bokaholimo. Sena se bohlokoa haholo lits'ebetsong tseo ho tsona ho ts'epahalang le ho tšoarella ha sebopeho, joalo ka litokiso tsa konkreite le likhabiso tse khabisitsoeng.
6. Ho lumellana le Li-additives: HPS e lumellana le lisebelisoa tse ling tse ngata tse atisang ho sebelisoa linthong tsa kaho, tse kang li-air-entraining agents, li-plasticizers le li-mineral admixtures. E ka kenngoa habonolo ka har'a liqapi ntle le ho ama hampe ts'ebetso kapa thepa ea likarolo tse ling, ho netefatsa botsitso le botsitso.
7. Tšireletseho ea Tikoloho: HPS e nkiloe mehloling ea starch e ka nchafatsoang le e ka senyehang, e etsa hore e be khetho e ntle ho tikoloho bakeng sa lits'ebetso tsa kaho. E ka thusa ho fokotsa ts'ebetso ea tikoloho ea merero ea kaho ka ho nkela li-additives tsa maiketsetso sebakeng sa mefuta e meng ea tlhaho.

hydroxypropyl starch ether e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso, ts'ebetso, le ho tšoarella ha thepa ea kaho. Ho boloka metsi a eona, ntlafatso ea ho khomarela, taolo ea rheology, le thepa ea thibelo ea crack e e etsa tlatsetso ea bohlokoa lits'ebetsong tse fapaneng tsa moaho, e tlatsetsang boleng le bophelo bo bolelele ba meaho e hahiloeng.
