Use: This product is mainly used as main raw material of cementconcrete admixture and can be

prepared to concrete antifreeze, rebar corrosioninhibitor, early strength agent, etc. This product can

also be used in heavyoil washing, lubricating oil emulsification, chemical organic synthesis andother

fields.
   

1. Antifreeze: Can reduce the freezing point of themixing concrete. Construction temperature can be

down to -25 °C. Negativetemperature can promote the hydration of mineral components in cement. It is a new generation of low-alkali chlorine-free antifreeze.


    2. Rebar corrosion inhibitor: It has excellentpassivation, rust resistance and protection effects.

Adding 2-3% calciumnitrite can prolong the life of buildings and structures for 20-50 years.


    3. Can prepare early strength agent to improve concretestrength, reduce cement consumption and

shorten construction period.


    This product fundamentally overcomes the defects ofconcrete alkali aggregate reaction and

electrochemical corrosion, improves thephysical and mechanical properties and durability of concrete

to get highquality concrete.


Packing: 25/40kg woven bag lined with plastic or according tocustomer requirements.


Q:citrate, What is the rationale for using a medium with this type of composition for the performance of the citrate utilization test?Thank you!
Simmons Citrate Medium
Q:Now need to determine the freezing point of inorganic salt solution, what kind of freezing point instrument is more accurate?
Because a large branch of antifreeze is with inorganic salt solution.
Q:I tried sodium and potassium carbonate and had little luck. Anyone know where to find the solubility data of inorganic salt in DMF?Thanks.
Sodium and potassium carbonate WILL dissolve in DMF. The best way to dissolve them is to... a) dry the solid inorganic salt in an oven (> 100 degrees C) overnight. b) pulverize the powder and grind several minutes with mortal and pestle. c) sonicate the mixture for several minutes...
