Guanding Customized Anti-Corrosion Spray Oven: Addressing the Diverse Challenges of Anti-Corrosion Scenarios

Anti-corrosion needs in the industrial sector have never been a "one-size-fits-all" solution. Municipal pipelines must resist soil corrosion and temperature fluctuations, chemical storage tanks need to withstand acid-base medium erosion, and marine components have to endure seawater salt spray impact. Significant differences exist in workpiece dimensions, coating types (epoxy, polyurea, fluorocarbon, etc.), and curing requirements across different scenarios. General-purpose anti-corrosion spray ovens often suffer from insufficient coating adhesion, uneven curing, and even shortened anti-corrosion service life of workpieces due to "fixed parameters and rigid structures".

The core value of customized anti-corrosion spray ovens lies in "taking customer scenarios as the core and creating truly adaptive anti-corrosion curing solutions based on coating characteristics, workpiece shapes, and working condition requirements". Shanghai Guanding Industrial Equipment, deeply engaged in the industrial anti-corrosion field, has developed a three-stage customization system of "coating process customization + workpiece structure customization + working condition compliance customization". This system ensures that each anti-corrosion spray oven accurately matches production needs, becoming a core equipment for customers in different industries to guarantee anti-corrosion quality.

I. Coating Process Customization: Anchoring Curing Characteristics of Anti-Corrosion Coatings to Avoid "Parameter Mismatch"

The chemical properties of different anti-corrosion coatings determine their unique requirements for drying temperature, heating rate, and constant-temperature duration—this is the technical starting point of customized anti-corrosion spray ovens. In the early stage of customization, Guanding first conducts an in-depth analysis of the technical parameters of the coatings used by customers, then reversely designs the temperature control system of the oven. The core customization points include:

Customization for Epoxy Coatings: Aiming at epoxy anti-corrosion coatings (requiring medium-temperature slow baking for cross-linking and curing) commonly used in municipal pipelines and steel structures, a curve of "80℃ preheating for moisture removal - 120℃ constant-temperature curing - 60℃ slow cooling" is customized. This avoids pinholes in the coating caused by sudden heating and cracking due to excessive cooling speed.

Customization for Polyurea Coatings: For polyurea coatings (needing high-temperature rapid curing to enhance medium resistance) used in chemical storage tanks and waterproof projects, a scheme of "150℃ high-temperature constant temperature + short-term curing" is customized. It is equipped with a high-frequency response heating module to ensure temperature fluctuation is controlled within ±3℃.

Customization for Fluorocarbon Coatings: For fluorocarbon coatings in outdoor high-weather resistance scenarios (such as bridge components), a process of "180℃ high-temperature curing + long constant-temperature shape retention" is customized. A PID dynamic adjustment algorithm is used to maintain stable furnace temperature, preventing the weather resistance attenuation of fluorocarbon resins caused by insufficient temperature.

This customization logic of "coating characteristics → process parameters → oven configuration" fundamentally avoids the quality risk of "using general parameters to adapt to multiple coatings", ensuring that each anti-corrosion coating can fully exert its performance.

II. Workpiece Structure Customization: Adapting to Workpiece Shape and Production Rhythm to Break "Structural Limitations"

The differences in the shape of anti-corrosion workpieces (long pipelines, large tank heads, irregular hardware) and production modes (batch continuous production, small-batch multi-batch production, single-piece large-size processing) are the core basis for structural design in customized anti-corrosion spray ovens. Through modular and adjustable structural design, Guanding solves the pain point of "workpieces adapting to equipment" in traditional ovens:

Customization for Long-Size Workpieces: For 6-12 meter long pipelines in municipal and oil transportation fields, a "segmented furnace chamber + continuous conveying system" is customized. The furnace length is designed according to the pipeline size, and the conveyor belt adopts a high-temperature resistant chain structure. Equipped with feeding and discharging guide devices, it ensures stable transportation of pipelines without collision. Meanwhile, an interface for the pipeline rotation mechanism is reserved to meet the demand of "360° uniform curing".

Customization for Large-Size Workpieces: For chemical tank heads and large steel structures, an "openable furnace chamber + hoisting inlet" is customized. The side door of the furnace is hydraulically driven and can be fully opened to facilitate workpiece hoisting. The inner wall of the furnace is made of high-temperature resistant stainless steel to avoid coating damage caused by friction between the workpiece and the furnace wall. The furnace volume is designed according to the maximum outer diameter of the workpiece to ensure hot air can evenly wrap the workpiece.

Customization for Small-Batch Multi-Batch Production: For small-size workpieces such as auto parts and hardware accessories, a "multi-layer drawer-type furnace chamber + rapid model change system" is customized. Each drawer can independently control temperature, supporting simultaneous drying of different coatings. It is equipped with a parameter storage function, allowing one-click retrieval of preset temperature curves during model changes to reduce debugging time, adapting to the production rhythm of multi-variety and small-batch.

In addition, for special workpieces (such as thin-walled parts and deformable parts), a "flexible hot air system" is customized. By adjusting the angle and speed of the air nozzles, it avoids workpiece deformation caused by excessive local air pressure, truly realizing "equipment adapting to workpieces rather than workpieces compromising to equipment".

III. Working Condition Compliance Customization: Balancing Regional Environmental Protection and Industry Safety to Eliminate "Compliance Risks"

Working condition requirements of different industries (chemical explosion-proof, municipal environmental protection, marine high temperature) and regional environmental protection standards (e.g., Shanghai has stricter requirements for VOCs emissions and energy consumption control) are indispensable links in customized anti-corrosion spray ovens. In customization, Guanding deeply integrates compliance requirements into equipment design:

Customization for Explosion-Proof Working Conditions: To meet the explosion-proof needs in chemical and oil-gas fields, "explosion-proof heating tubes + anti-static furnace chambers" are customized. The heating tubes adopt an explosion-proof structure, the control system uses an explosion-proof PLC, and the furnace grounding resistance is ≤4Ω, avoiding safety hazards caused by volatile coating gases.

Customization for Shanghai Regional Environmental Protection: In response to the environmental protection requirements of local enterprises in Shanghai, an "integrated system of VOCs collection + waste heat recovery" is customized. The air outlet of the oven reserves an interface for connection with RTO (Regenerative Thermal Oxidizer), ensuring efficient waste gas collection that meets Shanghai’s "Special Emission Limits for VOCs in Key Areas". At the same time, a waste heat exchanger is equipped to reduce the exhaust gas temperature from above 200℃ to below 80℃, reducing energy consumption.

IV. "Full-Cycle Implementation" of Customization Services: From Demand Research to Post-Service Adaptation

Guanding’s customization of anti-corrosion spray ovens is not a "one-time order" but covers the full cycle of "preliminary research - mid-term testing - post-service support":

Preliminary Research: The technical team visits customers to understand their coating types, workpiece sizes, and production rhythms. They even conduct on-site inspections of workshop layouts (such as door height and floor load-bearing) to ensure the customized equipment can be smoothly delivered and connected to the existing production line.

Mid-Term Testing: After the equipment is produced, small-batch workpiece test drying is first conducted. Parameters are adjusted based on coating adhesion testing (cross-cut method) and curing degree detection results until they fully meet the customer’s quality requirements.

Post-Service Support: Exclusive spare parts (such as heating tubes and air nozzles of customized sizes) are provided for the customized equipment. Local customers in Shanghai can enjoy 24-hour on-site debugging and maintenance services, while customers in other regions receive remote parameter optimization services to ensure long-term stable operation of the equipment.
