Impushana ye-polymer ehlakazeka kabusha ithuthukisa ubuthakathaka bodaka lukasimende lwendabuko olufana nokuphuka kanye ne-modulus enwebekayo ephezulu, futhi inikeza udaka lukasimende ukuguquguquka okungcono namandla ebhondi eqinile ukumelana nokubambezela ukwakheka kwemifantu odakeni lukasimende. Njengoba i-polymer kanye nodaka lwakha isakhiwo senethiwekhi esingena ngaphakathi, ifilimu ye-polymer eqhubekayo yenziwa ezimbotsheni, eqinisa isibopho phakathi kwama-aggregates futhi ivimbe ezinye ze-pores kudaka. Ngakho-ke, ukusebenza kodaka oluguquliwe oluqinile kuthuthukiswa kakhulu kunodaka lukasimende.
Njengento ebalulekile yokuhlobisa ekuhlobiseni, i-wall putty iyisisekelo sezinto zokulinganisa nokulungiswa kodonga, futhi iyisisekelo esihle seminye imihlobiso. Udonga olungaphezulu lungagcinwa lubushelelezi futhi lufana ngokufaka i-wall putty, ukuze iphrojekthi yokuhlobisa elandelayo yenziwe kangcono. I-wall putty ngokuvamile yakhiwa ngezinto eziyisisekelo, isicwenga, amanzi kanye nezithasiselo. Yimiphi imisebenzi eyinhloko yempushana ye-polymer ehlakazeka kabusha njengesithako esiyinhloko kumpushana we-wall putty?
① Imiphumela kudaka olusha;
A, Thuthukisa ukusebenza kokwakha;
B, Nikeza ukugcinwa kwamanzi okwengeziwe kuthuthukisa ukugeleza kwamanzi;
C, Khulisa ukusebenza;
D. Gwema ukuqhekeka kusenesikhathi
② Umthelela kudaka oluqinile:
A, Yehlisa imodulus enwebekayo yodaka futhi wandise ukufanelana kwayo nongqimba oluyisisekelo;
B, Khulisa ukuguquguquka futhi umelane nokuqhekeka;
C, Thuthukisa ukumelana kokuwa kwempushana.
D, Ukuxosha amanzi noma ukumuncwa okuncishisiwe kwamanzi
E. Khulisa ukunamathela kungqimba oluyisisekelo.
