Vacuum spray UV products and traditional PU product performance ratio
A. dosage contrast
Square meter of unit area.
1 PU product solid content: (paint: curing agent: =1:0.5:0.8)
2 paint solid content is 70%, the curing agent is: 45%.
3 the distribution of the paint is as follows: 41%. (1*0.7+0.5*0.45+0.8*0 = 0.925/2.3 = 0.4)
1 UV product solid content 100%.
2 utilization rate: PU product with spray paint as the standard, line and painting utilization rate is: 40%, waste 60%.
UV products without loss of waste for recycling, the conclusion of the same film PU products for the 6.25 times the amount of UV paint. That is, the UV product unit area supplies 30g, PU paint for 190g.
(1/0.4*0.41 = 6.25)
B. cost comparison
1.PU product price is 13.5 yuan / kg, curing agent 22 yuan /kg, the day of the water 12 yuan / kg, the proportion of mixed liquor at 15 yuan / kg.
2.PU product: 15 yuan /kg*190g = 2.85 yuan /m2
Class UV: average price 56 yuan *30 = 1.68 yuan //m2
3 conclusions: the cost of the PU class is nearly 2 times the cost of the UV product.
C. efficiency comparison
Class 1.PU: artificial paint, paint a two handling unit, 1 minutes 15m. The three person (excluding paint time per minute 15m products).
Class 2.UV 22~25 meters per minute, two individual operation can be. Eliminating human resources and improving the efficiency of 50%.
3 other PU class to be dry for at least 4 hours, and UV need to be reduced to two times to reduce manpower, improve work efficiency, accelerate the production cycle.
D. energy consumption contrast
PU class requires a row of wind, drainage, and UV no, UV has a vacuum pump and ultraviolet light, the energy consumption of the two flat.
E. environmental protection contrast
Modulation of PU lacquer VOC is far greater than 60%, and VOC national the the people's Republic of China air pollution prevention and control law "maximum allowable emission concentration shall not be higher than the 60mg/m3, the pollution to the environment has great influence, in the manufacturing industry in the future, there must be one day be strictly limited cannot continued survival and damage of the organic solvent to the operator, will cause no one is willing to engaged in this type of work. The UV product is closed cycle construction, without any leakage, almost reached the pure environmental protection, zero pollution. Such products is also the government support, employee satisfaction, enterprise development will be the way to go.
F. security comparison
1. PU products and traditional varieties mainly to organic flammable compounds of, belonging to CPI hazardous chemicals, the explosion-proof electrical site management has strict requirements, thus caused by fire and other accidents not pan paradigm.
2. UV products, non flammable, explosive, direct contact with the skin will not be in danger, there need not be explosion-proof facilities and down at the end of the fire and investment management, greatly reduces the production risk, increase safety.
To sum up a few points of two kinds of products, UV product price is superior to the traditional products, and calculated according to the stand-alone one-time investment of 25 million yuan every day single class production 8 hours calculation of production lines developed area to be 250px length, 25 meters per minute meter 0.1m*25=2.5m*60*8 hours = 1200m2, per square metre save 1.5 yuan, every single class save 1800 yuan, five months can save investment. Excluding the cost of the space occupied by the human resources.
The above data is only for reference, the actual data is calculated as the standard.
