Sodium for matehydrate: High-Purity Industrial Chemical Solution for Drilling, De-icing & Environmental Applications
Sodium for matehydrate (HCOONa·2H₂O) is a white crystalline powder. Its purity level fits industrial use. Plenty of plants depend on this formate salt for various processing jobs. Shanxi Zhaoyi Chemical Co., Ltd. has made acetate and formate chemicals since 1988. Industrial chemical solutions from this company stay stable and cost less. That solves everyday headaches in oilfield work. It helps with winter road upkeep too. Environmental treatment gets the same benefits. Every batch goes through quality control. ISO certification standards are what we follow, along with KOSHER and HALAL ones. Our plant takes up 27,000 ㎡ and puts out 150,000 tons a year. Storage and transport are where this dihydrate version holds up well, unlike anhydrous formate products. Caking and moisture sensitivity no longer cause trouble. A standard molecular weight of 68.01 g/mol lets you measure amounts accurately. It also keeps chemical reactions steady in all kinds of industrial formulations.

Key Features & Benefits
Thermal Stability: Downhole heat can reach 150°C. Even at that point, the dihydrate molecule keeps its shape. Heat resistance is strong, and breakdown stays very low. Drilling fluid viscosity stays where it should. The wider system keeps working too. High-temperature oilfield projects can then run without interruption.
Rapid Dissolution Profile: In water at room temperature (25°C), this product dissolves fully within three to five minutes. Urgent jobs suit this product best. Clearing snow and ice off roads during an emergency is one example. On-site mixing takes far less time, because the powder dissolves so fast.
Non-Corrosive Formulation: This product keeps metal structures safe. Drilling gear stays protected too, and so do car undercarriages. The reason is simple. No corrosive elements sit inside it. Chloride-based chemicals are the ones that carry those elements. Field data shows upkeep costs for equipment drop over time. Industrial assets also last 40% to 60% longer.
Eco-Friendly Biodegradability: Give it 14 days, and the product breaks down completely. What remains is carbon dioxide and safe water. Low toxicity and biodegradability make that happen. Companies find green manufacturing rules easier to meet. Pressure around trash disposal drops as well. Strict rules on environmental protection in North American and European markets get full compliance.

How It Works
Applied across multiple industrial fields, this product delivers targeted functional effects through stable physical and chemical mechanisms, adapting to diverse working conditions and production requirements.
In oilfield drilling operations, it acts as a professional density regulator and shale stabilizer. After dissolving in drilling mud, released formate ions form an effective inhibition environment to prevent clay hydration and swelling. This reduces bit friction during drilling and boosts overall penetration efficiency by 15%-20%.
The product uses a dual operating mechanism of latent heat release and freezing point depression for winter road de-icing and anti-icing. It provides 30% greater clearing efficiency than conventional rock salt for quicker road reopening by lowering the ice melting threshold to -15°C and speeding up the dissolving of ice layers.
It acts as an effective pH buffer during the pickling phase of the leather tanning process. It consistently preserves the ideal pH range of 2.8–3.2, encouraging consistent absorption and penetration of chromium agents, which significantly enhances the final leather goods' softness, texture, and durability.
Applications
Oilfield Development: A core additive for drilling fluids, workover fluids and completion fluids. It maintains stable performance in high-pressure and high-temperature oil and gas wells where conventional chemical additives fail easily, with a usable concentration range of 3%-8% adjustable according to actual formation conditions.
Winter Road Maintenance: Municipal maintenance departments in North America and Scandinavia know it well and use it. Preventive anti-icing is one use. Emergency de-icing is another. The standard dosage is 50-120 g/m². Compared with calcium chloride, it does far less damage to concrete infrastructure.
Leather Industry: In pickling and tanning baths, the dose is 0.5%-2.0%. Chrome tanning agents then absorb and get used much better. COD emissions in wastewater drop by 35%. That means lower sewage treatment costs for manufacturers.
Mining Operations: Here it acts as a flotation aid and also keeps pH in check during mineral separation. Sulfide minerals get activated, and that activation is selective. Recovery from copper and molybdenum ores climbs by 8%-12%. Mine economics improve as a result.
Reducing Agent Synthesis: It acts as a key precursor for sodium hydrosulfite. Textile printing and dyeing plants, along with paper mills, use that compound as a high-efficiency reductive bleaching agent.

Certifications & Compliance
The plant is certified to ISO 9001:2015 for quality management. So each batch comes out the same as the one before it. Our food-grade Sodium for matehydrate holds KOSHER and HALAL approval. That lets it serve pharmaceutical intermediate work and food auxiliary material uses. Every export shipment leaves with an official SGS inspection report. An MSDS that follows GHS Rev.7 goes with it. These two documents cover the rules for safety assessment and for reaching markets worldwide.

Packaging Options
Standard Industrial Grade: the product goes into three-layer woven bags. Each bag holds 25kg. A moisture-proof liner sits inside every one of them. One standard pallet carries 40 bags, so the total comes to 1000kg. Shrink wrap is then wrapped around each pallet. That way it travels safely inside a container.
Bulk Supply: the material is packed in 1000kg FIBC jumbo bags. Each bag comes fitted with discharge spouts. Buyers who order in bulk and restock often, such as large-scale oilfield enterprises, get a steady flow this way.
Customized Packaging: We provide 500kg IBC containers and personalized custom packaging services for orders over 20 tons to match diverse customer logistics and storage demands.

Manufacturing Process
Carbon monoxide is handled by our own production technology. Industrial sodium hydroxide meets carbon monoxide inside stainless steel reactors. There the temperature is held at exactly 160°C. Pressure stays at 0.6 MPa. The crude formate solution then passes through centrifugal impurity removal. Multi-stage crystallization comes next. Purity ends up at 98% and higher.
Quality control is tight. It covers the full production process. Food-grade batches also go through microbiological testing. Heavy metals are picked up by automatic X-ray fluorescence detection. pH is checked in real time. The closed-loop system reuses 92% of process water. Efficiency is kept high. The effect on the environment stays small.

FAQ
Q: How does Sodium Formate Dihydrate differ from anhydrous sodium formate?
A: A1: Sodium formate dihydrate carries about 22% crystal water. That water is what makes the product last longer in storage. Dust is lower too, so people handling it breathe in less. Now the anhydrous grade behaves the other way. Moisture goes into it fast. Damp air turns it into a caked lump. Long-term stock, then, suits it much less.
Q: Can this product go into food-grade applications?
A: A2: Yes. We do run custom food-grade batches for customers. Every batch comes with full KOSHER certification. Used as a preservative, the material meets E237 food additive standards. Local rules in your market still apply.
Q: How long does it keep, and how do I store it?
A: A3: Leave the bag closed. Warehouse humidity needs to stay below 60%. Do that and the shelf life goes up to 24 months. Damp air can make the powder cake a little. The main chemical performance of the product does not change. The way it applies stays the same too.
Q: What is the total lead time for a 20-ton shipment going to Los Angeles?
A: A4: From start to finish, the whole cycle runs about 30 days. Ocean freight takes eighteen to twenty-two days once payment is confirmed. Loading the container takes two days. Production and quality inspection need five to seven days.
Q: Do you have professional technical data you can give us for drilling fluid formulation?
A: A5: Sure. We provide scientific materials. They include density tables and viscosity curves at different concentrations. Compatibility info for common drilling additives like barite and xanthan gum is also part of it.
