Nowadays, unscrupulous manufacturers can artificially inflate the density of garbage bags, but they are quite easy to deduce. clean water. For this you will need simple tools and our table for calculating the correct weight of the bag at its declared density by the seller.

Let's understand what micronism is and why it is so important.

What is micronization of packages

Have you ever wondered why garbage bags from one manufacturer leak and break, while another can withstand heavy loads and tension, but remain just as strong and intact? All this thanks to different density bag: how much material the manufacturer will spend, how much polyethylene will stretch - the bag will have such strength. But how is this density measured? In millimeters? In grams per millimeter? In what degree?

So, to determine the thickness, there is a parameter - micronity (µm).

What is a micron?

A micron (µ, µ, µm, µm) is a unit of measurement taken as 10 −6 meters (1 µm = 0.001 mm = 0.0001 cm = 0.000001 m).

Why do you need to know the micron size of the package?

The indicator of micronity (thickness) of HDPE and LDPE packages will allow you to accurately determine what load the package can withstand, its load capacity.

What's wrong with garbage bags

Today, garbage bags are produced with a micron size of 4 microns and above. Some manufacturers indicate the density on the labels of their products, but it rarely reflects the actual thickness of the bag. In order to accurately determine the thickness of the goods, we offer on our website an accurate standard definition of the micron size of HDPE and LDPE garbage bags, which is calculated based on four parameters:

• Weight.
• Density.
• Areas (length, width).
• The coefficient for the type of raw material.

The micron index is important when we want to know exactly what load the packages are designed for. The lower the indicator, the less load the package can endure, and, conversely, the higher the micronization, the higher its load capacity.

How to independently determine the density of the bag

You will need the following things:

• Rubbish bag.
• Kitchen scales.
• Ruler.

Measure the width and height of the bag, write it down in our formula. Check the density of the bag with the seller - the density is measured in micrometers (µm). Substitute the resulting values ​​in our calculation table and check the resulting weight.

Now fold the bag compactly and weigh it on a household scale. If the seller is respectable, then the resulting value in the formula will not differ from the value on the scales.

You can use our weight formula:

More about length and distance

General information

Length is the largest measurement of the body. In three dimensions, length is usually measured horizontally.

Distance is a measure of how far two bodies are from each other.

Distance and length measurement

Distance and length units

In the SI system, length is measured in meters. Derived quantities such as kilometer (1000 meters) and centimeter (1/100 meter) are also widely used in the metric system. In countries that do not use the metric system, such as the US and the UK, units such as inches, feet, and miles are used.

Distance in physics and biology

In biology and physics, lengths are often measured much less than one millimeter. For this, a special value, a micrometer, has been adopted. One micrometer is equal to 1×10⁻⁶ meters. In biology, micrometers measure the size of microorganisms and cells, and in physics, the length of the infrared electromagnetic radiation. A micrometer is also called a micron and is sometimes, especially in English literature, denoted Greek letterµ. Other derivatives of the meter are also widely used: nanometers (1×10⁻⁹ meters), picometers (1×10⁻¹² meters), femtometers (1×10⁻¹⁵ meters), and attometers (1×10⁻¹⁸ meters).

Distance in navigation

Shipping uses nautical miles. One nautical mile is equal to 1852 meters. Initially, it was measured as an arc of one minute along the meridian, that is, 1/(60 × 180) of the meridian. This made latitude calculations easier, since 60 nautical miles equaled one degree of latitude. When distance is measured in nautical miles, speed is often measured in nautical knots. One knot is equal to one nautical mile per hour.

distance in astronomy

In astronomy they measure long distances, therefore, special values ​​are taken to facilitate calculations.

astronomical unit(au, au) is equal to 149,597,870,700 meters. The value of one astronomical unit is a constant, that is, a constant value. It is generally accepted that the Earth is located at a distance of one astronomical unit from the Sun.

Light year equals 10,000,000,000,000 or 10¹³ kilometers. This is the distance that light travels in a vacuum in one Julian year. This value is used in popular science literature more often than in physics and astronomy.

Parsec approximately equal to 30,856,775,814,671,900 meters or approximately 3.09 × 10¹³ kilometers. One parsec is the distance from the Sun to another astronomical object, such as a planet, star, moon, or asteroid, with an angle of one arcsecond. One arc second is 1/3600 of a degree, or about 4.8481368 mrad in radians. Parsec can be calculated using parallax - the effect of a visible change in the position of the body, depending on the point of observation. During measurements, a segment E1A2 (in the illustration) is laid from the Earth (point E1) to a star or other astronomical object (point A2). Six months later, when the Sun is on the other side of the Earth, a new segment E2A1 is drawn from the new position of the Earth (point E2) to the new position in space of the same astronomical object (point A1). In this case, the Sun will be at the intersection of these two segments, at point S. The length of each of the segments E1S and E2S is equal to one astronomical unit. If we postpone the segment through the point S, perpendicular to E1E2, it will pass through the intersection point of the segments E1A2 and E2A1, I. The distance from the Sun to point I is the SI segment, it is equal to one parsec when the angle between the segments A1I and A2I is two arcseconds.

On the image:

• A1, A2: apparent star position
• E1, E2: Earth position
• S: position of the sun
• I: point of intersection
• IS = 1 parsec
• ∠P or ∠XIA2: parallax angle
• ∠P = 1 arc second

Other units

league- an obsolete unit of length used earlier in many countries. It is still used in some places, such as the Yucatan Peninsula and rural areas of Mexico. This is the distance a person walks in an hour. Marine League - three nautical miles, approximately 5.6 kilometers. Lie - a unit approximately equal to the league. AT English language both leagues and leagues are called the same, league. In literature, the league is sometimes found in the title of books, such as "20,000 Leagues Under the Sea" - the famous novel by Jules Verne.

Elbow- an old value equal to the distance from the tip of the middle finger to the elbow. This value was widespread in the ancient world, in the Middle Ages, and until modern times.

Yard used in the British imperial system and is equal to three feet or 0.9144 meters. In some countries, such as Canada, where the metric system is adopted, yards are used to measure the fabric and length of swimming pools and sports fields and grounds, such as golf and football courses.

Meter Definition

The definition of the meter has changed several times. The meter was originally defined as 1/10,000,000 of the distance from the North Pole to the equator. Later, the meter was equal to the length of the platinum-iridium standard. Later, the meter was equated to the wavelength of the orange line of the electromagnetic spectrum of the krypton atom ⁸⁶Kr in vacuum, multiplied by 1,650,763.73. Today, a meter is defined as the distance traveled by light in a vacuum in 1/299,792,458 of a second.

Computing

In geometry, the distance between two points, A and B, with coordinates A(x₁, y₁) and B(x₂, y₂) is calculated by the formula:

How to determine the film thickness for a greenhouse

The main indicator when choosing a greenhouse film is the density, calculated in microns (µm). The fewer of them, the thinner the film, respectively, and its cost is lower.

But sometimes sellers are cunning, placing price tags with large numbers next to a thin "greenhouse". So, a very common option is when the “thickness” of 120 microns is sold at the price of a “thickness” of 150 microns.

Unfortunately, the forgery cannot be detected by touch: the density of the greenhouse film is determined only with the help of a special device - a micrometer. But there is a way out. We need to balance the weight with the footage.

1 mm contains how many microns

A linear meter of a film with a density of 80 microns should weigh 210 grams, a density of 100 microns - 260 grams, a density of 120 microns - 320 g, 150 microns - 400 g, 200 microns - 530 g. (Calculations are presented on standard width one and a half meters, "sleeve").

Let's count. If you buy ten running meters with a "declared" density of 150 microns, then total weight purchases should be equal to four kilograms (10X400 \u003d 4000g).

"Micron" redirects here; see also other meanings.

Micrometer(Russian designation: micron, international: mm; from Greek μικρός "small" + μέτρον "measure, measurement") is a long unit of length in the International System of Units (SI). Equal to one millionth of a meter (10−6 meters or 10−3 millimeters): 1 µm = 0.001 mm = 0.0001 cm = 0.000001 m.

micron (µm)

In 1879-1967 the name was officially used micron(mk, µ), which was then canceled by the decision of the XIII General Conference on Weights and Measures (1967/68).

The prefix micro-, which is used in the SI to form submultiple units, was adopted by the XI General Conference on Weights and Measures in 1960, simultaneously with the adoption of the SI as a whole.

Application

The micrometer is a standard unit of measurement in which the tolerance of deviations from a given size is expressed ( according to GOST) in mechanical engineering and in almost any production where exceptional dimensional accuracy is required. Micrometers also measure the wavelength of infrared radiation.

To better represent this unit of length, the following examples can be given:

micrometer, or micron(Russian brand micron, international - microns) - a measurement of the length of a unit in the International System of Units (SI).

A micrometer is one million meters or thousands of millimeters: 1 µm = 10-6 m = 10-3 mm.

The name "micrometer" comes from the Greek words μικρός - "small" and μέτρον - "measurement", "measurement".

Between 1879 and 1967, the name "micron" (μ, μ) was officially used and then it was annulled by the XIII General Conference on Weights and Measures.

Some facts:

• a person can detect light waves with a length of 0.38 to 0.78 microns;
• erythrocyte diameter is 7 µm;
• The thickness of a human hair ranges from 80 to 110 microns.

For mechanical engineering requiring exceptional dimensional accuracy, the micrometer is the standard deviation for deviations from a specific size.

A micrometer is used to measure the wavelength of infrared radiation.

Formally, the abolished metric unit is equal to 10 -6 (one millionth) of a meter. Notation µ. The name and symbol were adopted in 1879 by the International Committee for Weights and Measures (CIPM) and reapproved by Resolution 7 at the 9th General Conference on Weights and Measures (CGPM) in 1948. In 1967, the 13th CGPM conference abolished the unit "micron" (Resolution 7) and recommended the use of the term "micrometer" instead. For this unit of length in the SI system, the term "micrometer" is adopted (notation µm, µm). However, the term "micron" continues to be widely used in some areas, including the semiconductor industry. The term is often used to describe the size of particles trapped in air and water filters, the wavelength ranges to which optical instruments respond, and in machining. One of the uses where the use of this unit is currently legalized state standards, is a description of the quality of wool and other textile products (see www.ymccoll.com/micron_reports.html).

A micron is often found in the word millimicron = 10 -9 meters or 1/1000 of a micron. Notation mµ. Like the micron, the millimicron is an obsolete unit. The modern unit of the SI system, which has the same value, is the nanometer (designation nm, nm).
