Polystone test guides
Non-water-absorption
Polystone's water absorption is 0.03%, which is 1/300 of that of natural marble.
Ultraviolet resistance
There is no crack, bubble and color change on Polystone after 200-hour continuous intense ultraviolet radiation in artificial fast aging test. Its natural aging period is about 15 years.
High-temperature resistance
There is no change after a hot pan containing 180¡æ glycerine has been placed on Polystone panels for 20 minutes.
Pollution resistance
Nothing penetrates Polystone panels after lipsticks, shoeshine, hair oil, ink and crayons have been placed on Polystone panels for 16 hours.
Corrosion resistance
There is no change after citric acid, ammonia, iodine, gasoline, alcohol, acetone, sodium hydroxide, hydrochloric acid, gentian, hydrogen peroxide solution, urine, methylbenzene, acetic acid and amyl ester have been placed on Polystone panels for 16 hours.
Shock resistance
There is no change after a 210g steel ball with a diameter of 55mm has fallen freely from a place 60cm high and impacted Polystone panels.
Large load
There is no change after a 135kg load has been placed on a hung Polystone panel with the dimension of 610mm¡Á19mm.
Non-shrinking
There is no change after 250 times of 90-second impact on Polystone's surface with 88¡æ hot water, and 90-second impact with 21¡æ cold water successively.
Incombustible
Polystone panels do not burn and no flame appears after a lit cigarette has been placed on them for 2 minutes.
Use iron sharp-pointed object to squeeze the plate and observe the damaged point.
Mar resistance
¡ï¡ï¡ï
¡ï¡ï¡ï
¡ï¡ï¡ï¡ï
Use a heavy hammer to scrub surface of the materials and observe the mar.
Heat resistance
¡ï¡ï¡ï
¡ï¡ï¡ï
¡ï¡ï¡ï¡ï
Place a stainless-steel cup full of boiling water on the surface of table for 30 minutes and observe.
Yellowness resistance
¡ï
¡ï¡ï
¡ï¡ï¡ï¡ï
Expose a piece of small white plate to the sunshine for 3 days and then observe yellowness of materials.
Water resistance
¡ï
¡ï¡ï¡ï
¡ï¡ï¡ï¡ï
Spray some water on the surface of the table and after 24 hours, observe the albescent condition of the materials.
Pollution resistance
¡ï¡ï
¡ï¡ï¡ï
¡ï¡ï¡ï¡ï
Drip some soy bean sauce, vinegar, coffee on the surface of the table and after 24 hours, observe off-color condition of the materials.
Fire resistance
¡ï
¡ï¡ï¡ï¡ï
¡ï¡ï¡ï¡ï
Put the small strips of 10mm ¡Á 300mm on the fire for combustion test.
Break resistance
¡ï
¡ï¡ï¡ï
¡ï¡ï¡ï¡ï
Drop in full force the square pieces of 200mm ¡Á 200mm onto hard floor at a height of 1.5m from the floor surface and observe the break condition of materials.
Deformation resistance
¡ï¡ï¡ï
¡ï¡ï¡ï
¡ï¡ï¡ï¡ï
Fasten the two ends of the strip of 50 ¡Á 500, put heavy objects of 1000 gram on the middle of the surface and after 8 hours, observe the deformation condition of materials.
Resistance to heat variation
¡ï
¡ï¡ï¡ï
¡ï¡ï¡ï¡ï¡ï
Heat the small strips of 10mm ¡Á 200mm to the 130 ¡æ and after 30 minutes, conduct bending comparison .
Workability
¡ï
¡ï¡ï¡ï¡ï¡ï
¡ï¡ï¡ï¡ï¡ï
Use cutting machine to cut the plate and observe condition of pushing and plate slices.
Fineness
¡ï¡ï¡ï
¡ï¡ï¡ï¡ï
¡ï¡ï¡ï¡ï¡ï
Use fine abrasive paper of 1000 # to conduct sanding in the water respectively and then compare their fineness.
Appearance
¡ï
¡ï¡ï¡ï
¡ï¡ï¡ï¡ï¡ï
