Ƙarfin haɗin kai don ƙayyade mafi kyawun sashi.
5. Wakilin ƙarfi na farko
Wakilin ƙarfin farko shine ƙari wanda zai iya haɓaka haɓakar ƙarfin farkon turmi, mafi yawancin su ne inorganic electrolytes, kuma kaɗan ne mahadi na halitta.
Ana buƙatar mai haɓaka don turmi da aka shirya don ya zama foda da bushe. Calcium formate shine mafi yawan amfani da turmi mai gauraye. Calcium formate zai iya inganta farkon ƙarfin turmi, da kuma hanzarta hydration na tricalcium silicate, wanda zai iya rage ruwa zuwa wani matsayi. Bugu da ƙari, abubuwan da ke cikin jiki na calcium formate sun kasance barga a dakin da zafin jiki. Ba shi da sauƙi don agglomerate kuma ya fi dacewa da aikace-aikacen a cikin busassun busassun turmi.
6. Mai rage ruwa
Wakilin rage ruwa yana nufin ƙari wanda zai iya rage adadin haɗakar ruwa a ƙarƙashin yanayin kiyaye daidaiton turmi daidai yake. Mai rage ruwa gabaɗaya shi ne surfactant, wanda za'a iya raba shi zuwa na yau da kullun na ruwa, masu rage ruwa mai inganci, masu rage ƙarfi da wuri, masu rage ruwa, masu rage ruwa mai inganci da jawo masu rage ruwa gwargwadon ayyukansu. .
Ana buƙatar mai rage ruwa da ake amfani da shi don haɗakar turmi ya zama foda da bushewa. Irin wannan mai rage ruwa za a iya tarwatsawa daidai gwargwado a cikin busassun busassun turmi ba tare da rage rayuwar shiryayye na turmi da aka shirya ba. A halin yanzu, aikace-aikace na ruwa rage wakili a shirye-mixed turmi ne kullum a ciminti kai matakin, gypsum kai matakin, plastering turmi, waterproof turmi, putty, da dai sauransu Zabi na ruwa rage wakili dogara a kan daban-daban albarkatun kasa da daban-daban turmi Properties. Zabi.
