What are the precautions for the feed color printing woven bag during ultrasonic detection?

When the feed color printing and weaving bags, you need to pay attention to many details when performing ultrasonic detection.

These problems involve the operation of the instrument, the quality of the bag, and the standards for detection.

This article will introduce the precautions of color printing bags during ultrasonic detection.

1. Ultrasonic test introduction

Ultrasonic detection is a technology that uses sound waves to determine the internal defects of the measured object.

In the process of spreading, ultrasonic waves will be affected by the structure and defects of the measured objects.

By analyzing the changes in sound waves, the defects inside the measured object can be obtained.

At present, ultrasonic detection has been widely used in the field of defect testing in machinery, electronics, automobiles, aviation and other industries.

2. What is a color printed woven bag

Color seal weaving bags are a common packaging bag, which are mainly used in product packaging in agricultural products, toys, chemical industry and other fields.

Because color printing woven bags have the characteristics of low price, stable quality, and reusable use, etc., they are widely praised by users.

The material of the color printing woven bag is generally polypropylene. Polypropylene has the advantages of abrasion resistance, excellent cold resistance, and acid and alkali corrosion.

It is very suitable for products that need special requirements such as insulation and moisture -proof special requirements.

Third, the precautions of color printing and weaving bags during ultrasonic detection:

1. The quality of the bag

The quality of coloring and weaving bags is the basis for ensuring the accurate ultrasonic detection.

If the bag itself has quality problems, even after the ultrasonic detection, it is still impossible to rule out the possibility of defects in the bag.

Therefore, before the ultrasonic detection, the quality of the bag is needed to strictly control the quality of the bag.

Generally speaking, the higher the density of the bag, the better the quality, and the waterproofness and abrasion resistance of the bag will be better.

2. The standard for detection

When performing ultrasonic detection, corresponding detection standards are required according to different requirements of different bag types and uses.

For the detection standards for color printing woven bags, the corresponding standards can be developed in accordance with the size, material, use environment, size, shape, etc. of the bag.

If more accurate detection standards are needed, you can use the chemical composition analysis of raw materials,

Physical properties testing, molding process testing and other methods to formulate more diversified testing standards.

3. Operation debugging

When the coloring and weaving bags are detected in the ultrasonic inspection, a certain operation debugging is required to obtain accurate detection data.

You need to check whether the power supply, probes, display, computer, and writing board of the equipment need to be checked.

The permeability, sensitivity, strong sound, audio and scanning of the probe of the probe need to be performed.

Tracking management is required to perform operating records and archives to ensure the accuracy and controllability of detection accuracy and quality.

4. Safety measures

When performing ultrasonic detection, you need to pay attention to relevant safety measures to avoid accidents or damage equipment.

Generally speaking, the electromagnetic radiation of ultrasonic detection is relatively small and has little impact on the human body.

However, during testing, the cleaning and hygiene of the test site need to be guaranteed to avoid pollution or damage to equipment and probes.

In addition, to ensure that the operator can use the equipment correctly, it is not allowed to operate without professional guidance.
