The polycarboxylate water-reducing agent (powder) is the third-generation high-performance water reducing agent developed after the common water-reducing agent represented by wood calcium and the high-efficiency water-reducing agent represented by naphthalene series. It is currently the most in the world. A high-efficiency water reducer with cutting edge, highest technology content, best application prospect and best comprehensive performance. Polycarboxylate high performance water reducer is the most advanced water reducer product in the world. Compared with the performance of similar products at home and abroad, PC polycarboxylate high performance water reducer has reached the international advanced level in terms of technical performance index and cost performance. Polycarboxylate water reducing agent.
Features are as follows:
1. Low dosage and high water reduction rate: water reduction rate can be as high as 45%, which can be used to prepare high strength and high performance concrete.
2. The loss is small when the slump is light: the slump loss of ready-mixed concrete is less than 15%, which is very beneficial for long-distance transportation and pumping construction of commercial concrete.
3. Good workability of concrete: Concrete prepared with polycarboxylate water reducer will not have obvious segregation and bleeding phenomenon even in the case of high slump, and the appearance of concrete is uniform. It is very beneficial for the preparation of high-flow concrete, self-leveling cement, self-compacting concrete and clear water facing concrete. When used to prepare high-grade concrete, the concrete has good workability, good cohesiveness, and the concrete is easy to stir. .
4, small concrete shrinkage: can significantly reduce concrete shrinkage, significantly improve the volume stability and durability of concrete.
5. The alkali content is extremely low: the alkali content is ≤0.2%.
6, the product stability is good: no precipitation at low temperature.
7. Green and environmental protection products: The products are non-toxic and harmless, and they are green and environmentally friendly products, which are conducive to sustainable development.
8. Good economic benefits: The comprehensive cost of the project is lower than the use of other types of products. Application areas: self-leveling cement, grouting, grouting, high-flow concrete, self-compacting concrete, clear water facing concrete.
Fuse refers to an electric appliance that, when the current exceeds the specified value, melts the fuse and disconnects the circuit with the heat generated by itself.When the current exceeds the specified value for a period of time, the fuse melts and disconnects the circuit with the heat generated by the fuse itself.A current protector made from this principle.The fuse is widely used in high and low voltage power distribution system and control system as well as power equipment.
Ferrite is a metal oxide with ferrous magnetism.As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of single metal or alloy magnetic materials, and it has higher dielectric properties.Ferrite magnetic energy also shows high permeability at high frequencies.As a result, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current.Due to the low ferrite magnetic energy stored in the unit volume, saturated magnetic induction strength (Bs) and low (usually only pure iron 1/3 ~ 1/5), and thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.
