Product Description

Chemical Nature
 

Sodium nitrite is a more widely used antifreeze component that can be used when the hardening temperature of concrete is not lower than -16ºC. Soluble in water, sodium nitrite can be used as early strength agent to improve the early strength of concrete; As a rust inhibitor to prevent corrosion of steel bars;

Typical Properties

 

Appearance	White crystalline powder
Insoluble  in water	≤0.10
Sodium nitrate content	≤1.90
Loss on drying%	≤2.5
Assay%	≥98.0

Features of application

1. The anti-freezing effect is mainly to solve the damage effect of low temperature freezing damage on concrete engineering in winter.
2. The early strength effect can accelerate the condensation of concrete materials to a certain extent
3. Anti-rust action, sodium nitrite can be used in the construction material ratio process to prevent corrosion of steel bars

    Sodium nitrite is a sodium salt, will bring a lot of sodium ions into the concrete, there is a risk of triggering alkali aggregate reaction, should not be used in important structural concrete
 

Usage

The dosage can be adjusted according to engineering requirements after testing.

Storage

Products should be stored in a dry, clean environment, in their original packaging and away from heat sources. This product is not easy to fail, but it is a hydrophilic product, if the storage environment is poor, it will slowly inhale water, it is recommended to follow the principle of first in first out when using. If the product is not used up, the packaging must be tightly sealed to prevent moisture intrusion.
