लेटेक्स दस्तानों की उत्पादन लाइन की गति को कैसे समायोजित करें

The speed of a disposable glove production line is influenced by various factors, but the main factors include latex coagulation time, drying and vulcanization temperature, and demolding success rate. The following details how to optimize the production line speed for latex gloves.

1. Dipping Speed: Must match the viscosity and coagulation time of the latex solution, with the formula ratio determined through testing. Typically, the dipping time for latex solution is 3–10 seconds.

2. Drying/Vulcanization Speed: Determined by the degree of vulcanization. When the temperature is increased, the production line speed can be appropriately increased, but the vulcanization degree must be verified through glove tensile testing. The typical vulcanization conditions are 110–130°C for 20–60 seconds.

3. Adjustment Range and Quality Monitoring

The recommended adjustment range for production line speed is ≤5% each time, followed by checks for:

(1)Uniform glove thickness

(2)Presence of defects

(3)Whether tensile strength and elongation meet requirements.

4. After each speed adjustment, check whether the conveyor belt speed is consistent to prevent stretching or accumulation.

Potential Issues After Speed Increase

• Uneven Glove Thickness

Increased production speed shortens dipping time, leading to uneven thickness.

Poor latex fluidity may also cause this issue, requiring adjustment of thickener dosage.

• Demolding Difficulties

Insufficient vulcanization due to low temperature or short time—requires increasing vulcanization temperature or time.

Uneven release agent spraying may also cause demolding issues—check the spraying system.

• Bubbles on Glove Surface

Excessive speed traps air in the latex solution, forming bubbles.

Solution: Reduce speed or add a defoaming process.

• Sticky Gloves After Drying

Incomplete vulcanization due to excessive speed.

Solution: Increase vulcanization temperature or reduce speed to ensure full vulcanization.

Conclusion:

Increasing speed improves production efficiency but may accelerate wear on chains and molds. Additionally, higher speeds may increase defect rates, so cost-benefit analysis is essential.

Recommendation:

Before speeding up, manufacturers should prioritize glove quality stability, shorten machine maintenance cycles, and continuously optimize formula parameters (e.g., speed + temperature + dipping time) to adapt to speed changes.
