Indima yempushana ye-latex ehlakazeka kabusha odakeni

1. Indlela yokusebenza yempushana ye-latex ehlakazekayo odakeni

Inani le-emulsion polymer elingakhiwa ngokuhlakaza impushana ye-latex ehlakazekile emanzini lishintsha ukwakheka kwembotshana yodaka, futhi umphumela wawo wokungenisa umoya unciphisa ukuminyana kodaka, okuhambisana nokuncishiswa kwembobo okuphawulekayo nokusabalalisa okufanayo kulo lonke. . I-polymer yethula inani elikhulu lamabhamuza omoya amancane avaliwe afanayo odakeni lukasimende, okuthuthukisa kakhulu ukusebenza kodaka olusanda kuxutshwa. Ngesikhathi esifanayo, lawa mabhamuza omoya angavimba i-capillary ngaphakathi kodaka oluqinile, futhi ungqimba lwe-hydrophobic ebusweni be-capillary luvaliwe. Amaseli avaliwe; okubaluleke nakakhulu, lapho usimende uhlanjululwa ngamanzi, i-polymer iphinde yakha ifilimu futhi ibambelele ku-samente we-hydrate ukwakha isakhiwo senethiwekhi esifanayo, futhi i-polymer kanye ne-hydrate ingena komunye nomunye ukuze yenze isigaba esiqhubekayo. Lesi sakhiwo esiyinhlanganisela sakha i-polymer-modified Cement mortar, futhi iqoqo liphinde liboshwe odakeni oluqinile ngezinto eziyinhlanganisela. Ngenxa ye-modulus ephansi ye-elastic ye-polymer, isimo sokucindezeleka sangaphakathi sodaka lukasimende sithuthukisiwe, esingamelana nokuguqulwa nokunciphisa ukucindezeleka, futhi amathuba okuba nama-micro-cracks nawo amancane; ngaphezu kwalokho, i-polymer fiber iwela ama-micro-cracks futhi isebenza njengebhuloho nokugcwalisa Umphumela ukhawulela ukusabalala kwemifantu futhi wenza ukuqhekeka okuncane kunyamalale ezindaweni lapho kukhona ama-polymers amaningi. Ukuncishiswa kwemifantu emincane ngaphakathi kwe-slurry kunciphisa amandla okumunca amanzi we-capillary ngaphakathi kodaka, futhi amandla okumunca amanzi odaka athuthukiswa kanyekanye.

2. Ukumelana neqhwa

Izinga lokulahlekelwa kwenqwaba ye-frize-ncibilika yebhulokhi yokuhlola udaka lukasimende ene-latex powder liphansi kakhulu kunalelo lesampula ngaphandle kokwengeza i-latex powder, futhi ngokwanda kokufakwa kwe-latex powder, lapho izinga lokulahlekelwa kwenqwaba liba lincane, ngcono iqhwa. -thaw ukumelana ucezu test kuyinto. , lapho okuqukethwe kwe-latex powder kudlula i-1.5%, izinga lokulahlekelwa kwe-frize-thaw mass lishintsha kancane.

3. Umphumela we-latex powder ezintweni ezisebenza ngodaka

Amandla okucindezela odaka ayancipha ngokukhula kokuqukethwe kwe-latex powder, futhi uma exutshwe ne-cellulose ether, amandla okucindezela angancishiswa ngokuphumelelayo; amandla e-flexural namandla esibopho akhula ngokunyuka kokuqukethwe kwe-latex powder; Uma inani le-latex powder lingaphansi kuka-2%, amandla esibopho sodaka akhula kakhulu, bese ukwanda kunciphisa; i-latex powder ingathuthukisa kakhulu ukusebenza okubanzi kodaka, futhi inani elifanele liyi-2% -3% yezinto zikasimende.

4. Inani lemakethe kanye nethemba le-latex powder eguquliwe udaka lwezentengiselwano

Ukusebenzisa impushana ye-latex ukulungisa udaka lukasimende kungakhiqiza udaka olomile lwempushana enemisebenzi ehlukene, okunikeza ithemba elibanzi lemakethe lokudayiswa kodaka. Njengokhonkolo wezohwebo, udaka lwezentengiselwano lunezici zokukhiqiza okumaphakathi kanye nokuhlinzekwa okuhlangene, okungadala izimo ezivumayo zokwamukela ubuchwepheshe obusha nezinto zokwakha, ukusebenzisa ukulawulwa kwekhwalithi okuqinile, ukuthuthukisa izindlela zokwakha, nokuqinisekisa ikhwalithi yephrojekthi. Ukuphakama kodaka lwezentengiselwano ngokwekhwalithi, ukusebenza kahle, umnotho kanye nokuvikelwa kwemvelo kuye kwembulwa ngokwandayo kanye nocwaningo nentuthuko kanye nokuthandwa nokusetshenziswa, futhi kuyaqashelwa kancane kancane. Ingafingqwa ngamagama ayisishiyagalombili: eyodwa ingaphezulu, ezimbili ziyashesha, ezintathu zinhle, futhi ezine izifundazwe (esisodwa ngaphezulu, kunezinhlobonhlobo eziningi; ukonga abasebenzi, ukonga impahla, ukonga imali, akukhathazeki) . Ngaphezu kwalokho, ukusetshenziswa kodaka lwezentengiselwano kungafeza ukwakhiwa okuphucuzekile, kunciphise izingosi zokupakisha izinto ezibonakalayo, futhi kugweme ukundiza uthuli, ngaleyo ndlela kunciphise ukungcoliswa kwemvelo nokuvikela ukubukeka kwedolobha.
