household electric appliancesolutions

with the continued development of the domestic economy, improving people's living standards, consumer goods and household appliances requires not only more convenient and more comprehensive update function, but also for home appliances, environmental protection, quality and decorative appearance also put forward higher requirements, as a leading home appliance appearance of the surface coating surface treatment means, enjoy the opportunities but also facing unprecedented challenges. people are increasingly concerned about environmental protection and other aspects, hazards and damage to the living environment and the behavior of the industry will be subject to supervision and condemnation. household appliances industry, especially the coating on the plastic parts used in the paint is still present, most solvent-based coatings, the coating process will produce a lot of voc emissions, pollute the surrounding environment, the impact on people's health and safety , the state has introduced relevant policies on polluting industries will be mandatory implementation of cleaner production.

household electric appliance waterborne coating solutions

haolisen has developed a complete set of applicable solutions for various materials, requirements and processes through many years of research and practice in the household electric appliance industry. the solutions mainly include:
  • upgrade solution of household electric appliance metal powder coating
    e p coating upgrade process
  • one-step coating forming solution for household electric appliance aluminum alloy pieces
    application of nano-ceramics electrophoretic coating
  • ousehold electric appliance plastic parts waterborne coating solution
    application of waterborne plastic coating
  • coating solution of household air conditioning core parts
    application of low curing temperature electrophoretic coating
  • high corrosion prevention upgrade solution for central air-conditioning core components
    application of high performance waterborne coating

comparison between traditional powder coating process and e p coating process

in terms of process complexity, the electrophoretic coating saves many processes of draining and drying and greatly saves energy.
the overall coating after workpiece assembly is fully automatic, improving the overall efficiency.

e p upgrade process fills the traditional powder coating gaps for you
making your product coating more perfect

traditional powder coating process insufficiencies (p process) haolisen electrophoresis process complement (e process)
uneasy powdering and painting in the cavity and workpiece dead angles and poor hiding effect uniform internal and external cavity coating without dead angles and good hiding effect
thick film and poor physical and chemical properties moderate film and strong detection performance
low production process efficiency one-stage forming in coating assembly process and high efficiency
high production cost waste production recovery by 99% and low cost waste
mechanized artificial cooperation and high manual manufacturing cost mechanization management, stable quality and low personnel cost
waste dust affects the environmental safety zero fire point and safety without pollution (powder used in e p)

household electric appliance plastic parts waterborne coating solution
application of waterborne plastic coatings

currently, the plastic parts coating in the household electric appliance industry is faced with many challenges, mainly including environmental protection challenges, new material challenges and labor cost rise challenges. if effective coating solutions cannot be found under such challenges, the plastic parts coating in the household electric appliance industry will be undoubtedly headed into extinction. in the face of above challenges, it is required to replace traditional labor with popularization and application of waterborne plastic coatings and automatic spraying of manipulators from technical and process innovation to defend the position of the traditional coatings in the household electric appliance appearance decoration technology.

advantages of waterborne plastic coating

  • 01 no solvent or
    little solvent evaporation
  • 02 high effect
  • 03 high first pass yield
  • 04 low paint consumption
  • 05 high substrate defect
    hiding power
  • 06 no lifting, whitening or
    other poor coating phenomena
  • 07 non-flammable and no special
    requirements for fire protection

coating solution of household air conditioning core parts
application of low curing temperature electrophoretic coating

the epoxy resin used by conventional electrophoretic coatings is characterized by strong cohesion, corrosion resistance and good chemical stability. the traditional epoxy electrophoretic coatings, with the curing temperature of 170—200℃, can no longer meet the requirements for environmental protection and low energy consumption and are restricted in terms of the use of electrophoretic coatings of heat sensitive materials, to meet the needs for low temperature curing in current market and the basic requirements for low temperature curing in the future market, haolisen has taken many improvement measures, broken through traditional curing technique through independent research & development and reached 120℃ full curing.
  • level, smooth and fine film appearance; good bath solution stability and adaptability to long replacement cycle; adaptability to cold and hot rolled steel sheets and galvanized substrates and strong shrinkage cavity resistance; high throwing power, good internal and external homogeneity and little film thickness difference; strong rust protection and good secondary adhesion after salt spray on workpiece; good film fullness and good substrate hiding power; excellent film leveling property and good binding force and matching with floating coat and finishing coat; ultra low curing temperature and full curing at 120-140℃. as an energy conservation and emission reduction project absolutely valued and supported by the national government, it can save about 60% energy consumption in the coating process and benefit the nationa, the people and the enterprises; particularly apply to the workpiece that cannot be baked at high temperature, especially the binders of rubber and metal as well as zinc-aluminum alloy materials, such as refrigerator and air conditioner compressors, automobile absorbers and all kinds of steel pieces.

high corrosion prevention upgrade solution for central air-conditioning core components
application of high performance waterborne coating

the central air conditioning unit has more severe operating environment than the household air conditioner. the unit has high value, long service life and higher requirements for corrosion resistance. the core parts can be subject to corrosion prevention treatment to increase the service life. the high performance waterborne coating painting used meets the development trend of current coating technology.
more and more successful application examples prove that haolisen high performance waterborne coatings can provide good corrosion resistance performance for steel even under severe conditions. the waterborne coating is healthy, safe and environmentally friendly. with short drying and coating time, low insurance costs and without diluent cost, the waterborne coating is characterized by high coating performance and low cost caused by efficient construction.
