- Product Description
Industrial Grade Sodium Acetate Trihydrate - High-Purity Chemical Solution for Industrial Applications
SHANXI ZHAOYI CHEMICAL CO., LTD. makes industrial chemicals. We started in 1988. R&D has been a main focus since then. So has large-scale output of raw materials you can count on. Our standardized workshop takes up 27,000 ㎡. Output holds at 150,000 tons a year. That capacity sends Industrial Grade Sodium Acetate Trihydrate to industrial buyers around the world. Every batch goes through strict refining and processing. Purity comes in at 58-60%. Impurity levels stay very low. Chloride sits at ≤0.03%. It dissolves well in water. The material is mildly alkaline and buffers well. Sewage treatment uses it. So do textile processing and fine chemical synthesis. Other core industrial fields rely on it too. Buyers get a chemical solution that costs less and stays consistent.

Key Features & Benefits
Tough, complicated plant conditions are what we had in mind when we built our this product. Every part of the domestic industrial production standards is met. White crystals come out, and they are uniform. Effective content stays at 58-60%. Impurity control is tight. So run after run of continuous operation gives the same reliable performance.
Water dissolves it fully. No solids settle out. It will not crystallize while you mix and run the material. That cuts a few steps from on-site work. Alkalinity stays mild and stable. Its buffering effect holds pH adjustment accurate for a long time. Process parameter needs differ from plant to plant. Every one gets covered. Flow is good. The powder fights caking. Long storage will not leave lumps. Plants that buy it find storage and handling much easier.
Value for money is strong here. Industrial sewage plants pick it first when they need a carbon source. Municipal plants do the same. Moisture stays where it is. It does not drift. Put it in water and you get a mild alkaline solution. Those two traits fit many industrial jobs. Each production line draws something different from it.

How It Works
A steady neutralization reaction does most of the work, and acid-base buffering helps too. Those two mechanisms are what produce the industrial effects. Drop it into water and you get a mildly alkaline solution. The mix stays the same all the way through. Acid-base swings in the system get evened out as they happen. Over the long run, pH values hold steady, across many industrial processes.
Once it dissolves, the acetate ions go to work. They count as organic carbon. That carbon breaks down easily and stays active. Denitrifying microbes take it in right away. Nitrogen removal speeds up because of that. Sewage plants can then meet their discharge limits, and the readings stop bouncing around.
In textile dyeing and leather processing, it acts as a steady pH regulator and buffer. Sudden pH jumps no longer turn up in dyeing and tanning. Raw materials stay safe from damage. The drop in processing efficiency that comes with that damage gets avoided too. Output holds steady, and the finished goods come out reliable.
Applications
Wastewater Treatment: Municipal and factory sewage works use it as the main carbon source for biological denitrification. Nitrogen removal rises because of it. Treatment results stay more stable as well.
Textile & Dyeing: It acts as a professional pH buffer and a mordant in fabric dyeing. Dye pickup improves. Colour lands on the cloth evenly and with consistency.
Leather Processing: It serves as a supporting tanning agent and keeps pH at an exact level while hides are processed and finished. The tanning reaction conditions hold steady.
Chemical Synthesis: Many organic chemicals get made with it. Here it acts as a chemical intermediate, Industrial Grade Sodium Acetate Trihydrate, and helps catalysts do their job. Synthetic reactions then run efficiently.
Concrete Additives: Mixed into concrete, it holds back setting and works as an antifreeze part of the mix. Winter pours and cold-weather builds are where it fits. Construction quality stays where it should be.
Heat Storage Materials: Thermal energy storage systems rely on it as a key phase change material. Phase change behaviour holds steady. So does the heat storage behaviour.
Electroplating: It goes into buffer solutions for electroplating. pH stays steady in the bath and around it. The plating layer then builds up evenly and reliably.

Certifications & Compliance
All production procedures strictly comply with our enterprise standard Q/140902ZYH002-2020. Every batch of products will undergo comprehensive laboratory testing covering effective content, chloride ions, water-insoluble substances, iron ions and other core indicators to ensure full compliance with industrial standards.
We hold complete ISO quality management system certification to realize standardized and normalized full-process quality control. Meanwhile, we have obtained KOSHER and HALAL certifications to meet diverse compliance requirements for global export trade. We support SGS and Intertek third-party authoritative testing, with all technical indicators clearly specified in contracts, and provide unconditional return and exchange guarantees for non-compliant products.

Packaging Options
Standard Packaging: It comes in 25kg plastic woven bags. Inside each bag is a polyethylene liner. Two layers like that keep moisture out well. Storage from day to day is simple. Shipping is simple too. Lifting by hand on small and medium batch orders is no trouble either.
Bulk Packaging: For industrial users who need large volumes, 1000kg ton jumbo bags are on offer. Packaging waste goes down, and so does the transport cost per unit. Automated loading and unloading equipment handles these bags, which suits mass production.
Both packaging types feature durable and airtight structure to prevent moisture ingress and product deterioration during long-distance transportation and long-term storage. We also provide customized packaging solutions according to customers’ exclusive usage and shipping requirements.

Manufacturing Process
We adopt high-purity national standard acetic acid and sodium hydroxide as core raw materials. Through precise temperature and pressure control, stable neutralization reaction is carried out to generate qualified sodium acetate stock solution, ensuring raw material purity from the source.
The stock solution goes through multi-stage concentration, constant-temperature crystallization, high-speed centrifugation and precise drying processes. By optimizing drying temperature and centrifugal parameters, we accurately control the product’s crystal water content at around 40% to ensure stable product indicators.
We adjust the product crystal structure through professional technology to endow it with excellent anti-caking performance. Multiple rounds of sampling and inspection are implemented in each production link to strictly comply with enterprise standards, ensuring stable and consistent performance of every batch of finished products.

FAQ
Q: What is the smallest order you will accept for these products?
A: A1: Order quantities are flexible. A trial order can be just single bags. At the other end, large bulk container loads are also fine. That can fully meet the procurement needs of different customers.
Q: How should this item be stored?
A: A2: Store it in a dry, cool place. Airflow around it should be good. Moisture must not get anywhere near it. Strong heat causes trouble too. So do strong acids and oxidizing agents. Bring any of these close and the product will not work as well.
Q: Do you offer items made to custom specifications?
A: A3: Yes. We can adjust product indicators and provide tailored customized solutions according to customers’ specific industrial application scenarios and process requirements.
Q: How long does this product keep before it stops being usable?
A: A4: Leave the product sealed and dry when you store it as usual. Under those conditions, its chemical performance holds steady, and so does its quality, for as long as 24 months.
Q: Do you give technical after-sales support from professionals?
A: A5: Definitely. Our professional technical team provides free application guidance, parameter debugging and on-site problem troubleshooting support for all cooperative customers.
