Description

Technical Field

[0001] This utility model belongs to the technical field of general drying equipment, specifically relating to a flame-retardant coating drying device with detachable heat-conducting plates. Background Technology

[0002] Achieving flame retardancy in fabrics through spraying flame-retardant materials is a common surface treatment technology suitable for the rapid and low-cost flame-retardant retrofitting of existing ordinary fabrics. This involves uniformly spraying a liquid flame retardant (containing flame-retardant components such as phosphorus, nitrogen, and boron) onto the fabric surface to form a flame-retardant protective film. Its mechanisms of action include: 1. Isolating oxygen: The coating expands at high temperatures to form a char layer, preventing oxygen from contacting combustibles; 2. Absorbing heat and lowering temperature: The flame retardant decomposes and absorbs heat, reducing the surface temperature of the material; 3. Inhibiting free radicals: Interfering with the combustion chain reaction (e.g., phosphorus-based flame retardants generate phosphoric acid, inhibiting flame propagation).

[0003] When applying flame-retardant materials to fabrics, multiple layers are typically required. Multi-layer spraying significantly improves the stability, uniformity, and durability of the flame-retardant effect compared to single-layer spraying. Therefore, multi-layer spraying offers considerable advantages. Each layer must be dried after spraying (at room temperature or 60-80℃), and typically 2-3 layers are needed to achieve the standard flame-retardant effect. Drying each layer after spraying greatly reduces the waiting time between spraying operations.

This patent discloses a fixed arc-shaped heating element structure to significantly improve the heating efficiency of the heating element. However, this structure also has significant drawbacks.
