The foamed concrete foaming agent can make concrete appear a lot of foam to accelerate the formation and use of foamed concrete. Use efficiency and speed up the progress of the entire construction project. Foamed concrete foaming agents are available
There are mainly three indicators: foamability, foam toughness, and bleeding, to measure the quality of foaming agents.
Cement foaming agent refers two kinds: plant cement foaming agent and polymer foaming agent.
The properties of the cellular concrete are strongly influenced by the type of foaming agent used.
Foaming agents are substances that make the target material pores. It can be divided into three categories: chemical foaming agents, physical foaming agents and surfactants. Chemical foaming agents are compounds that can release gases such a
The invention discloses a method for preparing a calcium stearate water-based dispersion liquid. The method comprises the following steps: adding water and an emulsifier, dispersant, and 20-40% of the total content of a defoaming agent in a reaction kettle in a certain proportion, stirring until the emulsifier is dispersed uniformly, then stopping stirring, adding calcium stearate into the reaction kettle, then rapidly stirring until calcium stearate is completely wetted, then reducing the stirr
Glass powder itself is non-toxic, but if inhaled into the lungs, it can cause silicosis. Silicosis is a severe occupational disease that endangers health. It is mainly caused by long-term inhalation of silica dust, leading to pulmonary interstitial fibrosis and silicotic nodules. In extreme cases, it can affect lung function, cause loss of labor ability, and even develop into cor pulmonale, heart, and respiratory failure. The main glass component is silicon dioxide.. Glass powder harms the human
The touch screen digitizer is a thin layer of transparent plastic that reads the signal from the touch and transmits it to the processing unit.
