When it comes to display technology, in addition to the traditional LCD and LED liquid crystal display screen, OLED (organic light emitting diode) display technology has become a new mainstream.…
Polycarboxylate superplasticizer is the third generation of high performance superplasticizer after common superplasticizer and superplasticizer.…
Because the steric hindrance of the extended polymer side chain effectively hinders the secondary agglomeration between cement particles, so the product has high dispersion performance and can maintain this performance for a long time to realize the…
Common superplasticizers include lignosulfonates and their derivatives, advanced polyols and polyol complexes, hydroxy carboxylic acids and their salts, polyvinyl ethers and their derivatives, etc.…
Titanium Dioxide nanoparticle is a pigment with strong coloring power and strong hiding power in white coatings, so it is very familiar in the coating industry.…
In the summer when the temperature is high and the air humidity is low, due to the accelerated hydration reaction at high temperature, the moisture is easy to evaporate, the mortar fluidity loss is fast and the setting time is shortened, the construc…
Graphene is a two-dimensional crystal, which consists of carbon atoms with sp2 hybrid orbitals to form two-dimensional carbon nanomaterials with hexagonal honeycomb lattice.…
Polycarboxylate superplasticizer has more advantages than traditional naphthalene and aliphatic superplasticizer in mixing high strength grade concrete, but its advantages of high water reduction cannot be brought into full play when the strength is…
In order to improve the early strength of concrete, some manufacturers will add triethanolamine, calcium chloride and industrial salt to the superplasticizer, especially in winter or prefabricated component factories and cement products factories tha…
If the compatibility of polycarboxylate superplasticizer and cement is not good, the concrete mixture is prone to some problems, such as segregation, bleeding, greater slump loss, shorter setting time and so on, so that the concrete mixture can not b…
The wide application of mineral admixtures mainly derived from industrial solid wastes diversifies the composition of cementitious materials, which is one of the main characteristics of modern concrete.…
Adding polycarboxylate superplasticizer can make the compressive strength of precast concrete reach 40MPa grade at 8h to 18h.…
Water-based defoamer is mainly used for foam treatment in water-based systems such as water-based coatings and water-based inks. Easy to operate, with excellent defoaming and anti-foaming performance.…
Chile's government is considering phasing in a proposed ban on glacial mining to limit projects high in the Andes by some big copper companies. Chile's constitutional assembly has approved a proposal to ban mining in glaciers, protected areas, and ar…
The global shift to cleaner , greener energy appears to be accelerating agai n While the world focus on climate change has been taken a back seat to the COVID - 19 pandemic for most of the past 18 months , it has begun to return in a powerful way. In…
