Do you know the best way to convey concrete admixtures?

Keywords:CR, peristaltic pump


oncrete admixtures are chemical substances added in the mixing process of concrete, accounting for less than 5% of the cement quality, but can significantly improve the performance of concrete.
 
Concrete admixtures are characterized by large variety, small amount, large impact on concrete performance, with less investment, quick effect, significant technical and economic benefits.With the continuous progress of science and technology, admixtures have been applied more and more. Admixtures have become the fifth important component of concrete besides the four basic components.
 
Admixtures can improve the carbonation resistance of concrete. There is a linear relationship between the carbonation depth and porosity of concrete.Admixtures have a great influence on the frost resistance of concrete, and the concrete with aerated water reducer has better frost resistance...
  
Peristaltic pump plays an important role in the production of accurately measured admixtures:
Peristaltic pump concrete admixtures have the advantages of uniform feed, accurate measurement, easy to adjust the ratio of admixtures and improve the quality of finished products.Peristaltic pump by hose extrusion flow.The solution only flows through the hose and does not touch the pump body, effectively preventing the solution from corroding the pump body and blocking the pump body.Peristaltic pump has the advantages of simple cleaning, corrosion resistance, high temperature resistance and high cost performance.
 
Polycarboxylate superplasticizer is a new generation of high-performance superplasticizer and a cement dispersant in cement concrete.
Concrete mixed into the product, slump to maintain high performance, half an hour slump without loss, 1h slump loss is very small, with a low amount of admixtures, water reduction rate high, such as the advantages of shrinkage.Th
e addition of this product can greatly improve the fluidity of concrete, so that the condensate can maintain long-term construction performance;At the same time, the workability, physical and mechanical properties of concrete can be improved, and the engineering quality can be improved.It is widely used in precast cast-in-situ concrete, reinforced concrete and prestressed concrete of high-speed railway, passenger dedicated line, civil and industrial construction, highway, bridge, port, wharf, airport and other projects.
 
Acrylic acid is one of the important raw materials of water-soluble polymer.
The graft copolymerization with starch can produce high water absorbent.Widely used in medicine, leather, textile, chemical fiber, building materials, water treatment, oil extraction, paint and other industries.
 
The polypropylene solution is delivered stably to the reaction vessel through a peristaltic pump.
According to different requirements of production capacity and process, the conveying flow is generally 2-10 l/h in production, and 0.5-2cc /min in small tests.The completion time of each production or test is generally 2-4 hours.
  
Matters needing attention
Peristaltic pump and transmission hose need to resist acrylic corrosion;
The production workshop has high temperature and humidity, which requires high durability of peristaltic pump.
In small scale test, peristaltic pump is needed to drop materials smoothly and accurately.


 
High precision CR peristaltic pump
The calibration function ensures the filling precision of each injection, and the backdraft function prevents liquid backflow: in the distribution mode, after the direct circulation ends, the backstroke is started to prevent liquid from flowing out of the pump tube when stopping.
CR peristaltic pump no pollution: the fluid is only in contact with the pump pipe, not the pump body;
CR peristaltic pump is a multifunctional pump, can be used with a variety of products, can be used in a variety of industries.
CR peristaltic pump works simply. After the power is turned off and on, the control system keeps the current setting (pump head tubing model and other parameters).
CR peristaltic pump with good seal: it has good self-suction ability and can be idled to prevent reverse flow
Low shear CR peristaltic pump: ideal for conveying shear sensitive and corrosive fluids
