It has been reported by research data that in terms of friction loss alone, about 20% ~ 25% of the energy released by fuel combustion is consumed by the friction between parts under the working condition of the engine.Therefore, by improving the lubricati

Main factors affecting the thermal insulation performance of building self-insulated block and improvement measures.
We all know that foam concrete itself has low strength, bulk density is not easy to control, and porosity problems. These problems make foam concrete in the application process will have some limitations. Then the high performance foam concrete in the str
Foam concrete foam stabilizer refers to the material that can improve the bubble stability and prolong the half-life of foam bursting can be called foam stabilizer. Foam stabilizer has high surface activity, can effectively reduce the liquid in the liquid
Lightweight porous concrete mainly includes foamed concrete and aerated concrete, with the characteristics of light weight, heat preservation and insulation, sound absorption and sound insulation, fire prevention and non-combustion, etc., it is a kind of
