How to choose a carton testing instrument and what is the type of carton inspection

Carton testing instrument, I don't know the landlord's side, if it is moisture, you can choose Shenzhen Guanya SFY-60 carton rapid moisture detector, rapid sampling detection, a few minutes to complete the detection, in addition to the solid content of the pulp, moisture content can also be detected, suitable for a variety of samples, for the sample form particles, flakes, particles, pastes can be detected.

Summary. 1) Inspection of inner diameter size.

The first corrugated box is supported and formed, one end of the lid is closed, the angle of the adjacent surface is 90 close to the gauge, the inner cover is tightly attached with a pressing plate in the box, the outer cover of the top of the box is opened, the wooden ruler is placed horizontally on the inner cover, and then the distance of the bottom surface of the bottom of the wooden ruler is measured with an inner diameter ruler, which is the height of the inner diameter size. Use the inner diameter ruler to measure the distance between the two ends of the inner length direction of the box at 50mm from the mouth of the tongue or the middle of the first to second nails, which is the length of the inner diameter size. Use an inner diameter ruler to measure the distance between the two in the width direction of the box, that is, the width of the inner diameter size.

The use of the gauge is to ensure the squareness of the box placement. Under the weight of the platen, the box will not move and deform during inspection.

What are the types of carton inspections?

1) The inspection of the inner diameter size of the first corrugated box support molding, one end of the lid is closed, the angle of the adjacent surface is called 90 close to the gauge, the box is pressed with a pressure plate to make the inner shake cover close, the top of the box is opened, the wooden ruler is placed horizontally on the inner shake cover, and then the distance of the bottom surface of the bottom of the wooden ruler is measured with the inner diameter ruler, that is, the height of the inner diameter size barrier. Use the inner diameter ruler to measure the distance between the two ends of the inner length direction of the box at 50mm from the mouth of the tongue or the middle of the first to second nails, which is the length of the inner diameter size. Use an inner diameter ruler to measure the distance between the two in the width direction of the box, that is, the width of the inner diameter size.

The use of the gauge is to ensure the squareness of the box placement. Under the weight of the pressure plate, the sample box will not move and deform during inspection.

2) The inspection of moisture content At present, most of the tests of moisture content use needle-plug or silicone contact wood moisture meter. During the inspection, the test probe of the humidity meter is directly in contact with the surface of the corrugated box or inserted into the Wawu Pichangleng cardboard, and the arithmetic mean value is obtained by continuously measuring the sample, which is the test result. In order to ensure that the results of the hygrometer test are accurate and reliable, the results of the oven test and the hygrometer test can be compared.

3) Thickness inspection Measuring the distance between the planes on both sides of the corrugated cardboard, the value of the fifteen burning void obtained is the thickness of the corrugated cardboard. When measuring the thickness of corrugated cardboard, four pieces of 12 eggplant car specifications of 250mm and 200mm samples were taken from each sample box on the upper and lower shaking lids of the three sample boxes or the boxes without printing, indentation and damage as required, and the test was carried out after 24 hours under constant temperature and humidity environmental conditions. The environmental conditions of constant temperature and humidity are:

Temperature 23 2 , relative humidity 50 5 .

The inspection standards for packaging cartons are divided into three categories, namely, the dispatch of corrugated boxes for dust inspection, the performance test of Chunxun corrugated cardboard and corrugated boxes, and the type test of corrugated box dust.

I hope mine can help you and have a great day!

There are several ways to do this:

1. Measure its gravity on the earth with a spring dynamometer and divide it by the local gravitational acceleration.

2. On the earth (or any space where gravity exists), weigh the mass with a pallet balance.

3. In the weightless environment, the mass of the object with a known mass is calculated by the state before and after the collision with the measured object by using the momentum theorem.

4. If you consider the actual life, the carton is marked with the net content W, and the total mass G is measured, and G-W is the quality of the carton.

Yes? Carton? Don't look good at what it looks like?

Don't have to try to see if what's to be packed fits? Don't look at whether the pressure resistance or edge pressure is suitable for transportation and storage? Don't look at whether the burst resistance and puncture strength are strong enough to avoid accidental damage to the contents?

What are you worried about after these are qualified, and you don't have nothing to do to throw boxes to play, why do you fall?

The compressive strength of the carton is generally tested, and the edge pressure of the corrugated cardboard, the detection of the breaking resistance, and the fall. Piercing, waiting.

Generally, go to a third-party testing agency to do drop, puncture, pressure resistance and other physical properties testing.

We all hesitate for a long time before buying an item because we tend to choose the cheapest and the best quality. However, in the actual work, it is often caused by the company's budget, in fact, it is more difficult to choose paper packaging inspection instruments, especially in many businesses, I don't know, how to start to choose? I am also worried about the quality and after-sales problems.

Today, I will explain to you the issues that need to be considered when choosing paper packaging inspection instruments.

1. Is it a real manufacturer? Why this is very important, we all know in our hearts: the general factory direct sales of things are relatively cheap, because it eliminates some miscellaneous fees and freight costs from middlemen, and the cost is relatively low, so it is more preferential.

Second, how cost-effective paper packaging testing instruments: many users are very concerned about the quality of products, it is understood that Kunshan Haida paper packaging testing instruments are in line with many design standards at home and abroad, and many product parts are imported from abroad, such as carton compression testing machine computer servo, our motor generally uses foreign ones.

3. How about the after-sales service of the product? Many manufacturers often have a one-year warranty, but most of them are limited by time and geography, resulting in untimely after-sales service or after-sales service that cannot be guaranteed at all. Therefore, distance is also one of the most important factors when choosing.

Choose a close manufacturer after-sales service comparison***.

When we choose paper testing instruments, we consider the above three points, but the most important thing is to choose the best for yourself, so we must understand the needs of the product itself before purchasing.

7. Other tests:

1. Flat compressive strength test (ISO3035) (force per unit area) 2, bending stiffness test (IS05628) (four-point stiffness, calculated deformation force measurement) 3, surface water repellency (JIS-P8137) (refer to water repellency standard plate) 4, vertical compressive strength test (JIS-Z0403-2) (special fixture, special cutter) 5, moisture-proof performance test (GJB1109A) (250mm*250mm 4 pieces, 50 degrees 90% RH 48h, the difference between the front and rear moisture is not more than 5%)
