Materials for various antistatic products
How to choose anti-static gloves anti-static fabric?
Faults and disasters caused by static electricity generated by friction also occur from time to time. Therefore, the improvement of the antistatic property and the durability of antistatic properties of knitwear have attracted widespread attention. The application of antistatic fabric is one of the effective means of electrostatic protection. The fabric of antistatic gloves mainly uses synthetic fiber.
Anti-static gloves fabrics containing conductive fibers are made of electrostatic induction, corona discharge, leakage and other electrical effects to achieve antistatic properties. The process is as follows: the fabric is electrostatically charged by friction → the electric charge generated in the fabric is collected into the conductive fiber → the conductive fiber induces a charge opposite to the charge symbol on the fabric → an electrostatic field is induced near the conductive fiber, and the surrounding air is subjected to the electric field. The ions in the positive and negative ions generated by the ionization→corona discharge are opposite to the charge property of the fabric, and the ions are moved to the fabric and neutralized by the charge of the fabric → static electricity is eliminated.
Antistatic gloves Antistatic fabrics are available in four types: finishing, fiber chemical modification, conductive fiber blending, and conductive fiber embedding. The finishing type process is simple and low in cost, but not resistant to washing, and is greatly affected by the relative humidity of the air; the black of the fiber chemically modified antistatic fiber itself cannot be concealed in the light color fabric, affecting the appearance; and the conductive fiber blending type And conductive fiber embedded fabrics are widely used in antistatic fabrics because of their good electrical conductivity and excellent washing resistance.
Generally, fibers (20 ° C, 65% R.H) having a resistivity of 108 Ω/cm or less are collectively referred to as conductive fibers. Antistatic Gloves Conductive fibers are fibers that are electronically conductive and therefore have no humidity dependence and have much higher performance than the elimination of antistatic fibers and the prevention of static electricity. Mixing 0.5%-5% of conductive fiber in the fabric can solve the electrostatic problem of the fabric.
2. How to choose the antistatic hollow board of the hollow turnover box?
With the rapid development of the economy, hollow boards have gradually replaced traditional paper packaging. Because the hollow board is a green material, waterproof, shockproof, non-toxic, non-polluting, anti-aging, etc., it is used more and more widely in our daily life. Therefore, when we buy a hollow board, we must look at its quality, color, and reasonable price.
No matter how it changes, you need to choose the hollow board products that you use. In terms of thickness, it is usually the most used from 2 mm to 7 mm, which is determined by the cost and performance problems.
There are many indicators for selecting hollow plates, such as price, color, hygiene, safety, service life, bending, load bearing, flexing force, and cost performance. The overall summary has the following aspects:
1. Sealing test, this is the most basic and most important part.
2. Environmental protection of materials
3. Convenience of use
4. Cost of transportation and storage
5. Cost of packaging
6. The barrier to light and gas, the size of the headspace
When choosing a hollow board, we must first understand the knowledge of the hollow board. It is a green and environmentally friendly material. In this era of environmental protection, this material has certain advantages. In other places, it is called a hollow partition board. There are also different titles called Wantong board, corrugated board, etc. Although the titles are different, the actual nature is the same. If you want to buy hollow boards, how to choose the right one. (Note: Hollow panels refer to hollow panels produced at the factory, or hollow panels that appear in the market)
For the question of how to choose correctly, the purchaser must determine the target of selection before purchasing. Choose a manufacturer of hollow board that can produce the highest quality, or choose the brand of hollow board sales point. The target is confirmed. It is guaranteed to purchase a high quality hollow board. In addition, the quality of the hollow board must have a certain ability to distinguish.
For example, when you get a hollow board, judge its hardness resistance by its hardness. Of course, the machine inspection is the most reasonable, and its material is judged from its color. Some hollow boards also need For the box-breaking test, these strict requirements require the purchaser to have certain discriminating ability. If the purchaser is not clear about the identification method, he can quickly make up for his own shortcomings by reading some knowledge, which can also play a certain role in the selection.
The above is a few indicators for selecting hollow plates. When selecting hollow plates, special attention must be paid to the problem of sealing. This is especially important. Poor sealing will cause leakage of packaging, so special attention must be paid to the lack of sealing. Good must not be.
