查询词典 reducer

On the other hand, having greater absorptivity is the key factor for filtrate reducer to control water filtering, for filterability can not be materially controlled by macromolecular being unable to be effectively absorbed on the surface of cement granules.

在水泥颗粒表面有较强的吸附能力是降失水剂形成堵塞失水通道机制的关键因素，不能有效吸附在水泥颗粒表面的高分子，无法实质性控制体系的失水。

TH-904 is used as chelant in papermaking coating, building coating, concrete retarder, water reducer, woven and dyeing. Its performance can reach to that of SN-5040. Adding TH-904 to slurry during grinding process of bolus alba, lime carbonate, pottery clay, titanium pigment, French chalk, barium sulfate, coal-water slurry, etc., the viscosity can be largely reduced and the dispersed slurry is stable.

TH-904水性分散剂广泛用做造纸涂料及建筑涂料的分散剂、混凝土缓凝剂、减水剂以及纺织印染等行业作螯合分散剂，性能达到SN-5040水平，在高岭土、碳酸钙、陶土、钛白粉、滑石粉、硫酸钡、水煤浆及水泥等浆料的研磨加工过程中加入TH-904分散剂能极大地降低被加工物料的粘度，便于物料的加工，且分散后浆料粘度稳定。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
