Njenge-glue enhle kakhulu, i-hydroxypropyl starch ether ingathuthukisa kakhulu amandla okubopha phakathi kwezinto zokwakha nezinto eziyisisekelo. Lokhu kubaluleke kakhulu emikhiqizweni edinga ukunamathela okuphezulu, njenge-glue yethayela, i-putty, nezinto zokulungisa udonga. Kungathuthukisa ukumelana nokuxebuka kanye namandla okucheba kwezinto, ngaleyo ndlela kuthuthukiswe ukuzinza kwesakhiwo sonke.
Thuthukisa ukumelana nokuqhekeka
I-Hydroxypropyl starch ether ingathuthukisa ukumelana nokuqhekeka kwezinto zokwakha. Ingasabalalisa ngempumelelo ukucindezeleka futhi inciphise ukushwabana nokuqhekeka kwezinto, ngaleyo ndlela ithuthukise ukuqina kwezakhiwo. Lokhu kubaluleke kakhulu ezintweni ezidinga ukumelana nokuqhekeka okuphezulu, njengodaka olungangeni manzi kanye ne-wall putty yangaphandle.
Thuthukisa izakhiwo ze-rheological
I-Hydroxypropyl starch ether inezakhiwo ezinhle ze-rheological futhi ingagcina ukugeleza okufanele nokusebenza kwezinto zokwakha ngesikhathi sokwakha. Lokhu kubaluleke kakhulu emikhiqizweni edinga ukugeleza okuhle, njenge-mortar ezilinganisayo kanye nezinto zokufutha. Kungathuthukisa ukuthamba kanye nokuphela kwendawo yezinto, okwenza umphumela wokwakha ube muhle kakhulu.
Ukumelana namanzi okuthuthukisiwe kanye nokumelana nesimo sezulu
I-Hydroxypropyl starch ether ingathuthukisa ukumelana kwamanzi kanye nokumelana nesimo sezulu kwezinto zokwakha, okuzivumela ukuthi zigcine ukusebenza okuhle ezindaweni ezinomswakama kanye nezimo zezulu ezimbi kakhulu. Lokhu kubaluleke kakhulu ezintweni ezidinga ukumelana nesimo sezulu esiphezulu, njengezembozo zangaphandle zodonga kanye nezinhlelo zokuvikela zangaphandle. Kungathuthukisa ukumelana kwezinto ekugugulekeni kwamanzi futhi kwandise isikhathi sazo sokusebenza.
Izibonelo zokusetshenziswa kwe-hydroxypropyl starch ether
Iglue yethayela
Kuma-adhesive ethayela le-ceramic, i-hydroxypropyl starch ether ingathuthukisa amandla okubopha kanye nokugcinwa kwamanzi komkhiqizo, okwenza amathayela e-ceramic anamathele ngokuqinile ku-substrate. Ngesikhathi esifanayo, ingathuthukisa nokusebenza kokwakha futhi ivimbele amathayela ekusheleleni ngesikhathi sokwakha.
Impuphu ye-putty
Ku-putty powder, i-hydroxypropyl starch ether ingathuthukisa ukuqina nokusebenza komkhiqizo, yenze ukwakheka kube lula. Ingathuthukisa futhi ukumelana nokuqhekeka kwe-putty futhi inciphise ukuqhekeka.
Udaka oluzilinganisayo
Ku-mortar ezilinganisayo, i-hydroxypropyl starch ether ingathuthukisa ukugeleza nokusebenza kokuzilinganisa komkhiqizo, okwenza ukwakhiwa kube lula futhi kusheshe. Ngesikhathi esifanayo, ingathuthukisa nokumelana nokuqhekeka kanye nokuqina kwe-mortar.
udaka olungangeni manzi
Kuma-mortar angangenwa manzi, i-hydroxypropyl starch ether ingathuthukisa ukumelana namanzi kanye nokumelana nesimo sezulu somkhiqizo, okuwuvumela ukuthi ugcine ukusebenza kahle ezindaweni ezinomswakama. Kungathuthukisa futhi amandla okubopha kanye nokumelana nokuqhekeka kwe-mortar futhi kuthuthukise umphumela wokuvimbela amanzi jikelele.
Njengesengezo sezinto zokwakha ezisebenza ngezindlela eziningi, i-hydroxypropyl starch ether inamathuba amaningi okusetshenziswa. Ingathuthukisa kakhulu ukusebenza kwezinto zokwakha, okuhlanganisa ukuqina nokugcinwa kwamanzi, ukuthuthukisa amandla okubopha, ukuthuthukisa ukusebenza kokwakha, ukuthuthukisa ukumelana nokuqhekeka, ukuthuthukisa ukumelana namanzi kanye nokumelana nesimo sezulu, njll. Ngokusebenzisa okunengqondo kwe-hydroxypropyl starch ether, ikhwalithi nokuqina kwamaphrojekthi okwakha kungathuthukiswa kakhulu ukuze kuhlangatshezwane nezidingo zezakhiwo zesimanje zezinto zokwakha ezisebenza kahle kakhulu.
