Premium high-molecular polymers and advanced coagulants tailored for high-demand industrial processing, municipal wastewater, and advanced oilfield applications.
Foam generation in industrial fluid systems represents a critical physical chemistry challenge. It manifests as a dispersion of gas bubbles within a continuous liquid phase, stabilized by active surfactants present in the process media. Thermodynamically, foam is an unstable system with high surface free energy. Surfactants lower the surface tension of the liquid, forming elastic viscoelastic films at the gas-liquid interface that resist coalescence and bubble rupture (the Marangoni Effect).
To disrupt this stabilization, industrial operations rely on specialized Defoamer Liquids (also known as antifoams). Defoamer liquids must exhibit low surface tension and minimal solubility in the foaming medium, allowing them to penetrate and destabilize the surfactant-stabilized double layers. A highly effective defoamer performs three sequential actions:
The defoamer droplet enters the thin liquid film (lamella) between two adjacent gas bubbles. Because of its ultra-low surface tension, it spreads rapidly across the interface, displacing stabilizing surfactants.
As the defoamer spreads, it drags the underlying liquid away from the bubble junction, inducing local drainage and thinning the lamella below its critical rupture thickness.
The thinned film loses its mechanical integrity, leading to the rapid rupture of individual bubbles and the release of entrained gas, thereby eliminating surface foam.
Modern process chemistry classifies defoamer liquids based on their primary active carriers and hydrophobic components. Selecting the appropriate chemistry is essential to maximize efficiency and prevent downstream issues, such as silicone spotting in textile processing or paper sizing failures.
Established in 2011, Smedic Technology Co., Ltd. is a leading comprehensive solution provider specialized in environmental protection agents, integrating advanced research and development (R&D), large-scale production, global sales, and specialized engineering-related technical services. We are dedicated to providing global industrial and municipal clients with customized chemical products, high-efficiency technical formulations, and on-site engineering support.
Smedic's chemical production portfolio spans across multiple critical sectors, including municipal sewage treatment, high-concentration industrial wastewater, tap water purification, mineral processing agents, and specialized oilfield recovery chemicals. We offer a comprehensive suite of more than 80 different environmental protection products, with a consolidated annual production capacity exceeding 1 million tons.
Strategic regional positioning ensuring rapid logistical deployment and reliable chemical supply chain continuity for continuous process plants.
Our corporate headquarters is located in the political and technological center of Beijing. To ensure stable supply and minimize logistical costs, we operate multiple wholly-owned, state-of-the-art production bases in Hebei, Guizhou, Shanxi, and other resource-rich regions.
Furthermore, Smedic has established more than ten OEM partner factories and regional warehousing and logistics bases in key industrial provinces including Shandong, Shanxi, Anhui, Guangxi, and Sichuan. Our business and service network covers over 20 provinces across China, providing localized support to municipal and industrial customers.
To date, Smedic's environmental and process projects support more than 600 urban sewage treatment plants and over 1,000 end-users in heavy industrial wastewater treatment, mineral processing, and oilfield extraction operations. The daily liquid treatment capacity supported by Smedic chemicals exceeds 20 million tons.
Demonstrated commitment to innovation, quality control standards, and advanced chemical synthesis through deep academic collaborations.
Smedic has earned multiple highly prestigious national titles, reflecting our commitment to advanced technology development:
Our core technical team is composed of academic specialists, industry experts, university professors, and senior chemical engineers. We have built an R&D system centered around **one academy, three research institutes, and five bases**.
This structure is supported by the Hebei Provincial Enterprise Technology Center, the Advanced Water Treatment Chemicals Technology Innovation Center, and the Cangzhou Water Treatment Engineering Technology Research Center. We also operate a joint workstation with the Tsinghua University Association of Senior Scientists and Technicians, and maintain joint R&D laboratories with Shandong University and Beijing University of Technology.
We have been granted **over 60 Chinese patents**, including more than 40 core invention patents and 20 utility model patents. Smedic has led the drafting of **over 10 national and industry standards** for composite carbon sources, composite coagulants, sodium acetate, and specialized nitrifying bacterial agents.
Engineered defoamer formulations tailored to resolve foaming challenges and maintain hydraulic efficiency in high-shear, chemically active industrial environments.
Excessive foam in aeration basins and clarifiers disrupts microbial activity and causes structural overflow. Smedic's polyether defoamers provide targeted, temperature-dependent control, preventing biomass toxicity while reducing chemical oxygen demand (COD) loading on downstream processes.
Black liquor recovery, washing, and screening lines generate high foam volumes due to lignosulfonates. Our high-efficiency silicone and organic defoamer liquids accelerate drainage, prevent sheet breaks, and improve washing efficiency in pulp mills, reducing wash water consumption.
During drilling, cementing, gas-sweetening (amine units), and enhanced oil recovery (EOR), high temperatures and organic compounds generate persistent microfoam. Smedic's thermal-resistant defoamers maintain phase separation, protecting equipment and maximizing oil and gas throughput.
How Smedic's integrated manufacturing ecosystem and logistical footprint protect global operations from supply disruptions.
As raw material costs and global supply chain reliability fluctuate, Smedic utilizes its high-capacity production bases to provide clients with a highly resilient source of supply. Our primary facility operates under Industry 4.0 design standards, integrating automated batching systems, real-time reactor monitoring, and inline quality control analytics.
By directly purchasing primary chemical feedstocks and manufacturing core active ingredients in-house (such as silicone fluids, polyether block copolymers, and polyacrylamide structures), we isolate our customers from raw material market volatility.
Our decentralized warehousing infrastructure across major industrial shipping routes ensures that even during peak seasons or logistical disruptions, we maintain critical safety stocks. This allows us to offer short lead times for international deliveries out of major ports like Tianjin, Qingdao, and Shanghai.
Our quality assurance protocols cover three distinct phases to ensure reliable chemical performance in the field:
Maintaining compliance with chemical registrations and providing field engineering support to streamline international sourcing.
Deploying industrial process chemicals globally requires strict compliance with diverse regional regulatory frameworks. Smedic maintains full alignment with international chemical standards:
Recognizing that lab tests do not always predict performance in complex, dynamic industrial environments, Smedic provides comprehensive technical support:
Investing in sustainable, bio-based chemical platforms and smart dosing integrations to support green industrial initiatives.
To reduce dependence on petroleum derivatives, Smedic's R&D centers are developing defoamers based on natural vegetable oils and modified biopolymers. These offer high biodegradability and low environmental accumulation, meeting strict regulatory requirements for discharge water quality.
Traditional macro-emulsions can separate under high shear and temperature. Our research into nano-emulsion defoamers uses sub-micron active particles to deliver superior stability and consistent performance in challenging environments like high-speed paper machinery and textile dyeing.
We are partnering with automation companies to combine our chemical formulations with optical foam sensors and PLC units. These systems adjust defoamer dosing in real-time based on actual foam generation, reducing average chemical consumption by up to 30%.
