Product Description

The Impregnation Line is for (Applications):

 

The Impregnation line is for gluing melamine on the decorative paper to make the melamine paper.

 

Paper Impregnation line is used for decorative paper with Urea or Phenol or Melamine resins.

 

Such impregnated paper is used for making laminates or in pre-lamination of particle boards overlaying.

 

The resin gives the impregnated material strong mechanical properties, making it ideal as decorative laminates, industrial laminates, and laminates for melamine faced chipboards.

 

Types of paper used include Decor, Kraft, glass fiber, overlay, etc.

There are series one and two step impregnation line, 4' 5' 6' 7' and 8' paper width, biggest size of phenolic line at 12ft. it is the biggest size in the world.
 

1.1 Applications

The paper impregnation line use urea formaldehyde resin, phenolic adhesive to impregnate, coat, dry and stack paper base material.

With the decorative paper impregnation line, for the production of:

Melamine resin impregnated papers, for the Low-Pressure Laminates (LPL).

Melamine resin impregnated overlay paper, decorative paper and balance paper for flooring.

Melamine resin impregnated overlay paper for the High-Pressure Laminates (HPL)

Phenolic resin impregnated paper for plywood lamination.

1.2 Scope of application

The production line use fixed amount 40 ~ 250g/ square meters, width 900~1400 mm melamine/phenolic paper. The wet strength of melamine/phenolic paper is not less than 0.75kgf/15m.

1.3 Environment for line running

This production line is suitable for no corrosion and water soluble resin (Like urea resin, melamine and phenolic resin)

High-temperature resistant requirement: F level, Explosion-proof grade

Environment temperature: 10~40ºC

Relative humidity ≤90% (Temperature at 20ºC)

Altitude not more than 1000m

Part 2: Impregnation line parameters

2.1 General parameters

Model	NTC1500A-2-3 Two Steps Line
Width of raw paper	900~1400 mm
Max. roller width	1500 mm
Mechanical speed	4~100 m/min
Working line speed	15~18 m/min for melamine resin
Working height	1350 mm
Heating method	Thermal oil
Dryer working temperature	120~180ºC

2.2 Dimensions

Raw paper roll diameter	φ1100 mm
Weight of roll paper	1200 kg
In-diameter of paper axis	3''(76mm)
Dryer length	3750 mm
Effective drying length	(2+3)× 3750=18750 mm
Effective drying width	1500 mm
Total line length	~44,000 mm
Total line width	~3800 mm
Total line height	~4500 mm
Total line weight	~46,000 kgs
Operating area	On the right side, run along paper
Driving area	On the left side, run along paper

2.3 Power and energy consumption

Driven power	3 phase,380V,50Hz
Control power	2 phase,220V,50Hz
Total installation power	~125 KW
Heating medium	Thermal oil
Compress air pressure	0.5~0.7 Mpa
Compressed air consumption	~8 m^3/h as the installation volume
Cooling water pressure	0.2~0.4 Mpa
Cooling water consumption	~8 m^3/h at 45 degree temperature weather which means biggest volume, This is calculated by 60m/min speed volume, if line speed is 30m/min then means only consumption 4m^3/h

Remark: Compressed air volume means max. Demand which means at maintaining when all the cylinders are open need 8m3/h also means installation volume. While the normally running consumption is 0.5 m3/h. But when paper is broken or changing paper, need to open all the doors then that time consumption is 2m3/h. So to make sure the line can be worked at all conditions, need to prepare the 8m3/h compressor.

 

2.4 Line capacity calculation

The real capacity of this model impregnation line not only depends on the design of the machine, but also depends on the glue mixed, paper quality, and the temperature of working environment, wind capacity of recycling fan, the mature operation of the workers etc.

Calculation is based on:

Resin	Melamine
Temperature inside oven	120~180ºC
Raw paper density	80 g/m^2
Raw paper width	1300 mm
Resin contain of impregnated paper	130%~150%
Volatility of resin	6~7%
Working line speed	20 m/min
Working time	330 days/year x 3 shifts/day x 8 hours/shift

Production capacity per day for 4x8 feet paper:

15 m/min / 2.5 m  x 60 mins x 20 hours = 7200 sheets papers per day at least.
