Thermal Insulation Panel Machines

Sinowa is a thermal insulation panel machines factory in china, manufacturing pu insulation panel machine, rock wool insulation panel machine, phenolic insulation panel machine. In the field of building insulation materials, polyurethane insulation board, rock wool insulation board, and phenolic insulation board are the three mainstream products, each with their own unique production equipment.

sandwich panel machine

Polyurethane insulation board production machine

The pu insulation panel machine is a complete set of equipment specifically designed for producing polyurethane rigid foam insulation boards. Its core technology lies in precise raw material ratio and foam control.

The polyurethane insulation board production line mainly consists of the following systems:

• Raw material storage and metering system: including constant temperature storage tanks and high-precision metering pumps for polyols and isocyanates
  

• High pressure foaming machine: The working pressure is usually between 100-200 bar, and the mixing head adopts a self-cleaning design
  

• Continuous molding production line: composed of double track press, temperature control system, and automatic cutting unit
  

• Exhaust gas treatment device: for volatile organic compounds that may be generated during the foaming process

Technical features: The most significant feature of pu panel sandwich manufacturing line is the ability to achieve "online foaming", which means injecting the mixture directly between the two layers of material and completing the foaming and curing process within 30-60 seconds. The production speed of modern advanced equipment can reach 6-10 meters per minute, and the density of the board can be precisely controlled within the range of 30-60 kg/m ³.

Rock wool insulation board production machine

The core of the rock wool insulation panel machine lies in mineral melting and fibrosis technology, and the entire equipment presents the characteristics of high temperature and heavy industry.

The rock wool insulation board production line includes:

• Melting system: Cupola or electric furnace, working temperature can reach 1500 ℃ or above
  

• Centrifugal fiber forming equipment: Four roll centrifuge with a speed of 3000-5000rpm
  

• Cotton Collector: Forming preliminary cotton felt, equipped with negative pressure adsorption system
  

• Curing oven: temperature 200-250 ℃, containing formaldehyde removal device
  

• Vertical and horizontal cutting machine: diamond cutting tool, cutting accuracy ± 1mm

Production advantage: The most prominent capability of rock wool board manufacturing line is the ability to convert basalt and other ores into fine mineral fibers, with fiber diameters typically ranging from 4-7 μ m. The advanced pendulum method technology can achieve a three-dimensional distribution of fibers, significantly improving the strength of the product. The environmentally friendly equipment also integrates phenolic resin replacement technology and waste gas and heat recovery system.

Phenolic insulation board production machine

The phenolic insulation panel machine combines chemical reaction and board forming technology, and the equipment design needs to consider the resin curing characteristics.

The main equipment components of the phenolic insulation board production line are:

• Resin preparation system: phenol formaldehyde reaction kettle and pH adjustment device
  

• Pre mixed foaming section: including foaming agent injection and high-speed stirring equipment
  

• Compression molding machine: multi-layer hot press machine, pressure adjustable range 5-15MPa
  

• Post curing chamber: temperature gradient control accuracy ± 2 ℃
  

• Surface treatment line: including sanding machine and interface agent coating equipment

Process features: The key to phenolic board manufacturing machine lies in precise control of the condensation reaction. The latest technology adopts a second-order curing process, which first pre solidifies at low temperatures (60-80 ℃) and then solidifies at high temperatures (120-150 ℃), resulting in an oxygen index of over 36% for the product. Some high-end equipment has achieved fluorine free foaming technology, using environmentally friendly foaming agents to replace traditional HCFCs.

Based on the characteristics of the terminal product, equipment selection should consider:

• Building exterior wall insulation: Products produced by polyurethane board machine have the lowest thermal conductivity, making them more suitable for projects with high energy-saving requirements
  

• Fireproof isolation belt: A-level non combustible product of rock wool board machine is the only choice
  

• Special environmental applications: The boards produced by phenolic board machine have both B1 level flame retardancy and low smoke toxicity, making them suitable for places such as subways and tunnels
