Which specification do buyers overlook when sourcing compressor oil additives? Water separation. In metallurgy, mineral processing, and mica production, water-contaminated oil accelerates wear and forces unplanned downtime. DL32, a polyether polymer…
Applications & Markets
In metallurgical plants, mineral processing circuits, and mica beneficiation, air compressors are often the hidden backbone of operations. They drive pneumatic controls, flotation cells, and conveying systems. But compressor oil is vulnerable to water ingression from condensation, process moisture, and seal leaks. Water emulsifies with oil, reduces film strength, promotes rust, and can trigger varnish formation that clogs filters and valves. For sourcing teams, demulsibility—the ability of an oil to separate from water—is a specification that often gets overlooked until a compressor fails.
Against that backdrop, DL32, a polyether polymer demulsifier from Liaoning Hongyi Chemical Co., Ltd., enters the market as an industrial lubricant additive targeted at compressor oil formulations. The company lists the product under categories including Metallurgy, Mineral & Energy, Nonmetallic Minerals, and Mica, signaling its intended use in heavy-industry lubrication systems.
Application Scenarios
Metallurgy: In steel and non-ferrous metal plants, screw compressors supply instrument air and process air. Water contamination from cooling system leaks or high humidity can quickly degrade oil. A demulsifier like DL32 helps water shed rapidly, allowing it to be drained from the reservoir instead of forming stable emulsions.
Mineral & Energy: Mining operations, including coal and mineral extraction, run compressors in dusty, humid environments. Quick water separation supports longer oil life and reduces the risk of microbial growth in the lubricant.
Nonmetallic Minerals & Mica: Processing mica and other nonmetallic minerals often involves wet grinding and classification, creating moist air that enters compressor intakes. The additive’s role is to maintain oil cleanliness and protect against corrosion.
Product Description
DL32 is a polyether polymer demulsifier offered as a brown transparent liquid. Its general composition is listed as additives, and it is branded under the Hongyi name with China as the place of origin. According to supplier data, the product is intended for use as an industrial lubricant additive, specifically in compressor oil, with a viscosity grade of SAE 10W-20.
Key technical parameters provided by Liaoning Hongyi Chemical Co., Ltd. are summarized below.
| Parameter | Value |
|---|---|
| Product name | Demulsifiers Lubricant Additive |
| Application | Industrial Lubricant |
| Type | Compressor Oil |
| Viscosity Grade | SAE 10W-20 |
| General Composition | Additives |
| Appearance | Brown trans-parent liquid |
| Kinematic Viscosity (100°C), mm²/s | 10 min (as listed) |
| Density (20°C), kg/m³ | 850–950 |
| Flash Point (COC), °C | 105 min |
| Water Content, wt% | 0.03 max |
| Acid Value, mgKOH/g | 50–70 |
The product is sold as a single item, and the supplier lists a default SKU price of 4000 (currency not specified; contact for a formal quotation). The acid value range of 50–70 mgKOH/g is typical for polyether-based demulsifiers, which rely on controlled acidity to destabilize water-in-oil emulsions. The low water content specification—0.03 wt% maximum—indicates the additive itself is supplied essentially dry, a practical consideration for formulators.
Company Profile
Liaoning Hongyi Chemical Co., Ltd. is a China-based supplier whose product range, according to company data, includes lubricating oil additives, testing instruments, and extreme-pressure and antiwear agents. The seller’s catalog also lists engine oil additives and packaging-related items, suggesting a broader focus on lubricant chemistry and quality control.
The company identifies DL32 as one of its demulsifier products. While no additional corporate details are provided in the current product listing, buyers can request company qualifications and production documentation directly through the sourcing platform.
Quality & Compliance
No third-party certifications such as ISO or REACH are listed in the product data for DL32. Buyers should therefore request safety data sheets (SDS), technical data sheets (TDS), and any relevant compliance documentation before incorporating the additive into formulations.
From a quality standpoint, the product’s listed specifications offer some reassurance: a flash point of at least 105°C reduces handling risk compared with low-flash solvents, and the 0.03% maximum water content is stringent for a liquid additive. The brown transparent appearance is consistent with typical polyether demulsifier chemistries, though visual inspection alone cannot confirm batch-to-batch consistency. Category managers should ask for certificates of analysis (COA) for each lot and, if possible, arrange a small-scale trial in their own base oil and additive package.
Next Steps for Buyers
For sourcing directors evaluating demulsifiers for industrial compressor oil lines, the next step is to request a sample batch and full specification sheet from Liaoning Hongyi Chemical Co., Ltd. Confirm compatibility with your current base oil, additive package, and operating temperature range. Ask about lead times, packaging options, and minimum order quantities, as these details are not included in the listing.
Because demulsifier performance is highly formulation-dependent, a side-by-side bench test against your incumbent additive is recommended. Direct inquiries can be made through the platform’s supplier contact function.
