Kungase futhi kuthuthukise ukumelana nokugeleza nokumelana ne-delamination kodaka, okwenza ingxube ibe iyunifomu futhi ukwakhiwa kube bushelelezi.
Thuthukisa amandla ebhondi
Njengokunamathela okuhle kakhulu, i-hydroxypropyl isitashi ether ingathuthukisa kakhulu amandla okubopha phakathi kwezinto zokwakha nezinto eziyisisekelo. Lokhu kubaluleke kakhulu emikhiqizweni edinga ukunamathela okuphezulu, njengokunamathela kwamathayili, i-putty, nezinto zokulungisa udonga. Ingathuthukisa ukumelana nokucwecwa kanye namandla okugunda impahla, ngaleyo ndlela ithuthukise ukuzinza kwesakhiwo sonke.
Thuthukisa ukumelana nokuqhekeka
I-Hydroxypropyl starch ether ingathuthukisa ukumelana nokuqhekeka kwezinto zokwakha. Ingahlakaza 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 inezinto ezinhle ze-rheological futhi ingagcina uketshezi olufanele nokusebenza kwezinto zokwakha ngesikhathi sokwakhiwa. Lokhu kubaluleke kakhulu emikhiqizweni edinga uketshezi oluhle, njengodaka oluzilinganisayo nezinto zokufutha. Ingathuthukisa ukucaba nokuqedwa kwendawo yezinto ezibonakalayo, okwenza umphumela wokwakha ube muhle kakhulu.
Ukumelana kwamanzi okuthuthukisiwe kanye nokumelana nesimo sezulu
I-Hydroxypropyl starch ether ingathuthukisa ukumelana namanzi kanye nokumelana nesimo sezulu sezinto zokwakha, okuzivumela ukuthi zigcine ukusebenza kahle ezindaweni ezinomswakama kanye nezimo zezulu ezimbi kakhulu. Lokhu kubaluleke kakhulu ezintweni ezidinga ukumelana nesimo sezulu esiphezulu, njengezimbotshana zodonga zangaphandle kanye nezinhlelo zokuvikela ezingaphandle. Ingathuthukisa ukumelana kwempahla ekugugulekeni kwamanzi futhi yandise impilo yayo yesevisi.
Izibonelo zokusetshenziswa kwe-hydroxypropyl isitashi ether
I-tile glue
Ezinamathiselwe zamathayili e-ceramic, i-hydroxypropyl isitashi ether ingathuthukisa amandla okubopha kanye nokugcinwa kwamanzi komkhiqizo, okwenza amathayili e-ceramic abambelele ngokuqinile ku-substrate. Ngesikhathi esifanayo, ingaphinde ithuthukise ukusebenza kokwakhiwa futhi ivimbele amathayili ukuthi angasheleli ngesikhathi sokwakha.
I-putty powder
Ku-putty powder, i-hydroxypropyl starch ether ingathuthukisa ukujiya nokusebenza komkhiqizo, yenze ukwakhiwa kube bushelelezi. Kungaphinde kuthuthukise ukumelana nokuqhekeka kwe-putty futhi kunciphise ukuqhekeka.
Udaka lokuzilinganisa
Odakeni oluzilinganisa, i-hydroxypropyl starch ether ingathuthukisa uketshezi kanye nokusebenza okuzilinganisa komkhiqizo, kwenze ukwakhiwa kube lula futhi kusheshe. Ngesikhathi esifanayo, kungase futhi kuthuthukise ukumelana nokuqhekeka nokuqina kodaka.
udaka olungangeni manzi
Emasikeni angangeni manzi, i-hydroxypropyl isitashi ether ingathuthukisa ukumelana namanzi kanye nokumelana nesimo sezulu somkhiqizo, okuwuvumela ukuthi ugcine ukusebenza kahle ezindaweni ezinomswakama. Kungase futhi kuthuthukise amandla okubopha kanye nokumelana nokuqhekeka kodaka futhi kuthuthukise umphumela wokuvimbela amanzi.
Njengesengezo sezinto zokwakha ezisebenzayo, i-hydroxypropyl starch ether inamathuba abanzi okusebenza. Ingathuthukisa kakhulu ukusebenza kwezinto zokwakha, okuhlanganisa ukuqina nokugcinwa kwamanzi, ukuthuthukisa amandla okubopha, ukuthuthukisa ukusebenza kokwakhiwa, ukuthuthukisa ukumelana nokuqhekeka, ukuthuthukisa ukumelana kwamanzi nokumelana nesimo sezulu, njll. Ngokusebenzisa okunengqondo kwe-hydroxypropyl starch ether, ikhwalithi nokuqina. wamaphrojekthi wokwakha angathuthukiswa kakhulu ukuze ahlangabezane nezidingo zezakhiwo zesimanje zezinto ezisebenza kahle kakhulu.
