Home Appliance PPGI Steel Sheet

Home Appliance PPGI Steel Sheet

Homeappliance PPGI steel sheet refers to the prepaintedgalvanized steel sheet used for home appliance exterior decoration. It is alsocalled home appliance precoatedsteel, and coil coated steel, etc. PPGI steel sheet is a type of high gradecolor coated steel sheet.

As compared with construction color coated steel sheet, the home appliance PPGIsteel sheet has higher requirement on its external quality such as colordifference and surface flatness, etc. Hence, during the production of householdappliance PPGI steel sheet, there are special requirements on substratematerial, painting material, production equipment and production techniques,etc.

Our home appliance PPGI steel sheet utilizes home appliance standard hot-dipgalvanized steel plate as the basic substrate material, and is coated withorganic coating. Home appliance PPGI requires high flatness zinc coating, soits zinc coating thickness is smaller than that of construction galvanizedsteel. Therefore, home appliance PPGI steel sheet is not suitable for outdoorwall cladding and roof construction uses.

With elegant appearance,high flexibility, superior corrosion resistance and processing capability, homeappliance PPGI steel sheet provides an environmental friendly material forindoor architectural decoration and external decoration of piano, varioushousehold appliances and electrical appliances, and more. To illustrate, it canbe used in manufacture of refrigerator, washing machine, microwave oven, airconditioner, water heater, water dispenser, computer case, and more.

Home Appliance PPGISteel Sheet Processing Requirements
When processing home appliance PPGI steel sheet intodesired home appliance housing shape, please pay attention to the followingrequirements.
1. Environmental requirement
Before processing homeappliance galvanized steel sheet, please make sure the surface of die andprocessing equipment is clean.
2. Mould exactness
High exactness die should be used. The die, which directlycontacts with the PPGI steel sheet’s coating material, is recommended to bechrome plated and finely polished.
3. Accuracy
The die should come with correct amount of clearance between the punch and die,so as to ensure accurate end product size and shape. The clearance can beadjusted according to the total thickness of substrate, paint coating, and 70%thickness of protection membrane.
4. Lubrication and heating up processing
Lubricating the die and protection membrane of the home appliance PPGI steelsheet, and heating up the steel sheet, can greatly improve the product surfacequality and entire processing effect.
