Polyurethane Flame Retardant Foam Sandwich Panel Machine

The polyurethane flame-retardant foam sandwich panel machine is a professional production line integrating machinery, chemical industry and automatic control. Its core is to realize the accurate proportion of polyurethane raw materials, efficient foaming and the composite process with surface materials.

The polyurethane flame-retardant foam sandwich panel machine is usually composed of main modules such as foaming system, conveying system, composite system, cutting system and control system. It completes the whole production process from raw materials to finished products through highly automated processes.

PU flame-retardant foam sandwich panel machines are mainly divided into continuous production line and intermittent production line.

• The continuous pu flame-retardant foam sandwich panel production line adopts the flow process mode, which can achieve uninterrupted production, high efficiency, stable product quality, and is suitable for large-scale industrial production;

• The intermittent polyurethane sandwich panel production line is more suitable for flexible production needs of small batches and multiple varieties.

In terms of achieving flame retardant performance, modern production lines mainly use three technological paths:

• Using additive flame retardants, the flame retardant components are mixed into the polyurethane raw material system before foaming;
  

• Using reactive flame retardants to make them part of the polyurethane molecular chain;
  

• Flame retardant treatment is applied to the formed board through post-processing technology.

The core technology of polyurethane flame-retardant foam sandwich panel equipment is embodied in three aspects: foaming system, composite process and control system. The performance of the foaming system directly determines the quality of foam. Modern high-pressure foaming machines use multi-component precise metering technology to ensure thorough mixing of raw materials. Intelligent control system is a hallmark feature of modern equipment. A control system based on PLC and industrial PC has achieved closed-loop control of multiple variables such as foaming parameters, temperature, and speed.

Polyurethane flame retardant foam sandwich panel has been widely used in many fields due to its excellent performance. The construction industry is the largest market, with products used for walls and roofs in large factories, cold storage facilities, clean workshops, etc.
