Yenza udaka olusha oluqukethe ukugcinwa kwamanzi okuhle:

Inqubo ye-Cement Hydration inqubo ehamba kancane, njengokuthi usimende awukwazi ukuxhumana namanzi isikhathi eside, usimende ngeke ukwazi ukuqhubeka nokuthatha ama-hydration, ngaleyo ndlela kuthinte ukuthuthukiswa kwamandla kamuva. Udaka olushintshiwe lwe-polymer lunamandla aphezulu kunenani elijwayelekile, isizathu ukuthii-polymer polymer powderkuthuthukisa amandla okugcina amanzi, ukuze amandla okomakha akhuphuke. Okwesibili, ukwakheka kwesigaba esincane se-polymer kudaka, kuthuthukise amandla webhondi.

Thuthukisa ukusebenziseka kokwakhiwa kodaka okusha:

Ngemuva kokungeza i-polymer popular evuselelwayo owesimende oxutshwe ngodaka, ukusebenziseka kodaka kuthuthukiswa kakhulu, ikakhulukazi ngenxa yezizathu ezilandelayo: , ungqimba lwe-coating lungavimbela ukuhlangana okungaguquki phakathi kwezinhlayiya ze-polymer ukuze kube nomphumela wokuthambisa phakathi kwezinhlayiya, Izinhlayiya ze-polymer zingahlakazeka ngokulinganayo kusisindo se-slurry kasimende, lezi zinhlayiya ezihlakazekile, njengokuthwala kwebhola, kungenza izakhi zodaka zigeleze ngokwehlukana futhi zithuthukise ukusebenziseka kodaka. B. I-Redisperperfressible Pelmer Powler ngokwayo iqukethe umphumela wokulinganisa umoya, i-polymer powder emphumela wokungeniswa komoya kufanele inikeze ukuxabana kodaka, ukuze udaka lube nokusebenza okuhle kokwakhiwa. Ngaphezu kwalokho, ukuba khona kwama-bubble amancane nakho kudlala indima evuthayo engxubevange yengxube ukuze kuthuthukiswe ukusebenziseka kwenhlanganisela.

I-polymer polymer powderUkuze uthuthukise ukuguquguquka nokuvimbela ukumelana nodaka:

Kamuvai-polymer polymer powderKunezelwa kudaka, isilinganiso sokucindezela kodaka kanye nesilinganiso se-tensile sathuthukiswa kakhulu, esibonisa ukuthi ubucwebe bodaka buhliswa kakhulu, ukuqina kwenziwa ngcono kakhulu, ukuze ukumelana nokuqhekeka kodaka kwenziwa ngcono.i-polymer polymer powderEfilimu lokuzivocavoca ngodaka, hhayi kuphela ukugcwalisa ukushiyeka nama-pores etsheni likasimende, kodwa futhi nasemikhiqizweni ye-centhydration kanye ne-modulus ye-aggreer yefilimu ye-polymer iphansi kunaleyo ngodaka, ngakho-ke ubucwebe bodaka kuyancishiswa. Ukuguquguquka kodaka kwandisa umkhawulo wezenkolo ophakeme wodaka lapho kulinyazwa, futhi amandla adingekayo yisiphene nokusakazeka okungama-micro-ukuqhekeka kudonswa ngezinga elikhulu, ukuze udaka lukwazi ukubhekana nengcindezi enkulu ngaphambi kokwehluleka. Ngaphezu kwalokho, ifilimu le-polymer liqukethe indlela yokuzelula, futhi ifilimu le-polymer lakha amathambo aqinile ku-motime hydrate daterate, okuqukethe umphumela wokuhlangana oguqukayo, ukuqinisekisa ukuqina kokuqina kanye nokuqina kwe-skeleton eqinile. Kunama-pores ngaphezulu kwefilimu ye-polymer eyakhiwa ebusweni bezinhlayiya zodaka, futhi ama-pores agcwala udaka, anciphisa ukugxila kwengcindezi futhi akhiqize ukuphumula ngaphandle komonakalo wamandla angaphandle. Ukuba khona kokuguquguquka okuphezulu nendawo ephezulu ye-elasticity polymer nakho kuthuthukisa ukuguquguquka nokuqina kodaka.
