Njengoba isisho sithi, "uchwepheshe ubheka emnyango, umuntu ovamile ubheka isixuku", amandla okuqala kasimende akhula ngokushesha, amandla kamuva akhula kancane, uma izinga lokushisa nomswakama kufanelekile, amandla ayo asengakhula kancane kancane. iminyaka embalwa noma eyishumi. Ake sikhulume ngokusetshenziswa kwe i-calcium formateukuxazulula inkinga yokubeka usimende nokuqina.
Isikhathi sokusetha singenye yezinkomba zokusebenza ezibalulekile zikasimende
(1) I-hydration kasimende yenziwa kancane kancane ukusuka phezulu kuya ngaphakathi. Ngokuqhubeka kwesikhathi, izinga le-hydration likasimende liyanda, futhi imikhiqizo ye-hydration iyanda futhi igcwalisa ama-capillary pores, okunciphisa i-porosity yama-capillary pores futhi ngokuhambisanayo kwandisa i-porosity ye-gel pores.
I-calcium Formate ingakhuphula ukugxila kwe-Ca 2+ esigabeni se-liquid, isheshise izinga lokuqedwa kwe-calcium silicate, futhi umphumela we-co-ionic uzosheshisa i-crystallization, ukhulise ingxenye yesigaba esiqinile odakeni, okulungele ukwakheka kukasimende. isakhiwo samatshe.
Ukuhlakazeka kanye viscosity ofi-calcium formate odakeni zacwaningwa ngokuhlaziya ukubukeka kwayo, ukucoleka, okuqukethwe okuhlelekile nokuncibilika emanzini abandayo. Izakhiwo zemikhiqizo ye-calcium formate namandla ebhondi kudaka lokuplasta kwahlolwa futhi kwaqhathaniswa.
izinga lokushisa
(2) Izinga lokushisa linomthelela omkhulu ekumisweni nasekuqineni kukasimende. Lapho izinga lokushisa likhuphuka, ukusabela kwe-hydration kuyashesha, futhi amandla usimende akhula ngokushesha. Lapho izinga lokushisa lincipha, i-hydration iyancipha futhi amandla akhula kancane. Lapho izinga lokushisa lingaphansi kuka-5℃, ukuqina kwe-hydration kuncipha kakhulu. Uma izinga lokushisa lingaphansi kuka-0℃, ukusabela kwe-hydration kuyama. Ngesikhathi esifanayo, ngenxa yezinga lokushisa elingaphansi kuka-0° C, lapho amanzi eba yiqhwa, azobhubhisa isakhiwo samatshe usimende.
Emazingeni okushisa aphansi, umphumela wei-calcium formatekuzwakala nakakhulu.I-calcium Formateiyi-coagulant entsha yokushisa ephansi namandla okuqala athuthukiswe e-China, kanye nezakhiwo ezibonakalayo ze i-calcium formateazinzile ekamelweni lokushisa, akulula ukuwahlanganisa, alungele ukusetshenziswa odakeni.
umswakama
(3) Itshe likasimende endaweni enomswakama lingakwazi ukugcina amanzi anele okukhipha amanzi kanye nokufingqa nokuqiniswa, futhi ukufakwa kwamanzi okukhiqizwayo kuzogcwalisa izimbotshana futhi kukhuthaze amandla etshe likasimende. Izinyathelo zokugcina izinga lokushisa kanye nomswakama wendawo ezungezile, ukuze amandla etshe likasimende aqhubeke nokukhula, abizwa ngokuthi ukugcinwa. Lapho kunqunywa amandla usimende, kufanele welashwe kuze kube yiminyaka ethile kumazinga okushisa ajwayelekile kanye nemvelo yomswakama.
I-calcium Formatei-ejenti yamandla yakuqala iyi-ejenti yamandla ekhonkolo yokuqala enebanga elibanzi lohlelo lokusebenza nomphumela omuhle. Inani elikhulu locwaningo lokuhlola luye lwafakazela ukuthi ukusetshenziswa kwe-calcium formate i-ejenti yamandla yakuqala kunomthelela omkhulu ekunciphiseni isikhathi sokusetha nokuthuthukisa amandla okuqala kakhonkolo, futhi kungavimbela ngempumelelo ukulimala okuqandisiwe kukakhonkolo ngaphansi kwezimo eziphansi zokushisa.
