914mm-1250mm PPGL steel coi / Weathering heat reflective color plate
PPGL Steel coil introduction :
PPGL steel coil usually the galvanized steel,GL after
surface treatment on their surfaces coated with a certain thickness
of the adhesive coating or layer of organic film,after
curing,become a color plate,with excellent corrosion
resistance,molding,decoration in the building,home appliances,light
industry,transportation and other industries widely used as an
ideal composite material.
The production of weather-resistant heat-reflective color coated
plate to solve the common color coated plate to absorb high heat
and reduce the service life of the problem is eco-friendly products
and energy saving products pioneer, while making the roof is called
"cold roof."
Product performance indicators in:
The initial solar reflectance (TSR)> 0.25 for all colors, and
the sunlight reflectivity (TSR)> 0.15 for three years;
Most of the products (except for a few dark products) of the sun
reflection coefficient SRI ≥ 29, part of the light-colored products
SRI ≥ 78;
The product has excellent scratch resistance, the use of probe
scratch tester test load 1500 grams, the film is not Li broken;
Resistance to heat and humidity, after non-condensing hot and humid
test chamber placed 1000 hours, the product without bubbles,
cracks, paint peeling, no color, gloss and hardness changes;
Resistance to boiling water, the product in 100 ℃ boiling water
bath for 24 hours, no loss of light, discoloration, cracking,
blistering, shedding and so on;
