Calculation method of cluster density of artificial turf
We buy the grass when the usual 16800 needle is how to calculate it? I below for everyone to bring a point of artificial turf cluster density calculation of the way to explain:
Turn to the back of the lawn, which is called a cluster of each needle. "Cluster density" refers to the number of grass per square meter, usually 16800 needles / m2, 18900 needles / m2,22050 needles / m2.
"Cluster density" is how to calculate it? We all know that the area of the rectangle is multiplied by the width, so the "cluster density" is calculated in the same way.
The length of the "cluster density" calculation is called "number of stitches", and the number of stitches is 10 cm in length, usually 16-pin, 18-pin, 21-pin.
The width of the "cluster density" calculation is called "pitch", since the beginning of the lawn production machine is imported, so the unit is feet. Normally kindergartens use a lawn of 3/8 feet, or 0.9525cm.
To give an example, take the length of each 1m piece of "needle" for the 16-pin, line spacing of 3/8 feet of the lawn, it is 1 square meters. 1m is equal to 100cm, so the length of a meter with 160 needles. Width divided by 100 by 0.9525 for about 105 knots. So the cluster density is 105X160 = 16800 needles / m2
