Description
Sodium salt of polynaphthalene sulphonic acid, also known as Sodium polynaphthalene sulfonate, is a chemical additive with superplasticizing properties that is widely used in various industries. It is known for its ability to reduce the amount of water required in construction and concrete applications, resulting in more durable and resistant products. As a high-efficiency water reducer, it contributes to significant cost savings. Additionally, it is used as a dispersant in the dye industry. It is typically available in a yellow-brown powder or liquid form and is soluble in water. However, it may cause irritation to skin and eyes, and proper precautions should be taken if ingested.
Uses
Used in Construction Industry:
Sodium salt of polynaphthalene sulphonic acid is used as a superplasticizer for improving the workability and reducing the water content in concrete mixtures. This results in a more durable and resistant final product, contributing to cost savings and enhanced structural integrity.
Used in Concrete Applications:
Sodium salt of polynaphthalene sulphonic acid is used as a high-efficiency water reducer, which allows for a reduction in the amount of water needed in the concrete mix. This leads to a stronger and more resilient concrete, ultimately improving the overall quality and performance of the construction material.
Used in Dye Industry:
Sodium salt of polynaphthalene sulphonic acid is used as a dispersant, which helps in the even distribution of dye particles in the dyeing process. This ensures a more uniform and consistent color application, improving the quality of the final product.
Check Digit Verification of cas no
The CAS Registry Mumber 36290-04-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,2,9 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 36290-04:
(7*3)+(6*6)+(5*2)+(4*9)+(3*0)+(2*0)+(1*4)=107
107 % 10 = 7
So 36290-04-7 is a valid CAS Registry Number.
