How is the opening ratio of the perforated mesh calculated?
First of all, let's understand the concept of porosity
The opening rate is the effective sieve rate area. The scientific name is "screening rate", and it is also called "opening area" at home and abroad. A ratio of sheet area), expressed as a percentage. The size of the opening ratio represents the size of the available screening area.
The regular hexagonal hole can maximize the opening rate, so the regular hexagonal hole punching mesh is widely used in industrial production.
So how is the porosity calculated?
Let's take an example below, such as a circular mesh with a hole diameter of 2mm, a staggered arrangement of 60 degrees, a center distance of 4mm, and an overall size of 1mx2m. According to these information, we can conclude that the opening rate of the perforated mesh of this specification is about 23%, that is to say, the sum of the area of the punched holes is 0.46 square meters (1mx2mx23%).
This is the calculation method of the opening rate of the punching net.
