In the field of bag type dust, if you have to use a bag to collect dust, it is necessary to make a dust bag filter with anti-static properties, which is   called antistatic filter bag .   General concentration of industrial dust to some extent (explosion limit) can easily lead to explosion and fire if subjected to electrostatic discharge of spark or external combustion and other factors. Such as: surface dust, chemical dust, coal dust, etc., if exposed to electrostatic discharge, an explosion or fire may occur.

Features of antistatic filter bag

• 1. High refined filter efficiency: reach 99.5
• 2. Excellent anti-wear
• 3. Stable working time: maximum more than 4000 hours. Can be used cyclically.
• 4. Quality and cost-effective

Mainly research shows, manufacturer of filter cloths and filter bags, dust filter products and other comprehensive environmental protection products are used as dust collection and treatment bags. Particles that pile up and increase in size tend to  use antistatic filter bags  . Large particles are easily filtered and some particles have an electric charge and can absorb the opposite charge, and if the charge of the particles and the fibers are the same, the electrostatic charges have a negative effect.

When the dust of common industrial powders approaches a certain density in the air such as flour dust, industrial powder dust, coal dust, etc., if there is a static flame or spark, it can easily lead to fire. .

In that part of the bag dust collection, if the dust needs to be filtered or collected, the filter media used for the dust filter bags should be anti-static and we should use an  anti-static filter bag  .

In order to produce an antistatic filter bag fabric, we   need a technology of mixing anti-static fiber yarns, or a base fabric yarn used to make perforated felt fabrics, or a mixture of conductive fibers and chemical fiber conductors.

An anti-electric bag is used to store electronic components, which are prone to damage due to electrostatic discharge. (ESD)

Static anti-electric bags, as the name implies, are made of standard polyethylene with a static coating or a layer on plastic. This prevents a static load from forming on the surface of the bag, as it drops the load to the ground (ie any other surface it touches). In this sense, it is really “static anti-electricity” because it prevents the formation of static charges. However, it is not resistant to electrostatic discharge.

If something else touches the bag at once (such as a person’s hand), the cost is easily transferred through the bag and its contents. These bags are usually pink or red due to the chemical layer of expansion. There are also black bags, in which polyethylene is made, which contains small amounts of carbon.

Conductive antiperspirant bags are made with a layer of conductive metal, often aluminum, and a plastic dielectric layer coated in a static expansion coating. It forms both a shield and a non-conductive barrier. These bags are preferred for sensitive areas, but can also be used in areas where hazardous sparks are present, such as oxygen-rich areas on airplanes and in hospitals. Metal bags are more fragile than their asymmetrical counterparts, however, because of each hole, the correctness of the shield is compromised. In addition, they have a limited shelf life, as the metal substrate can deteriorate over time. These bags are often dark due to the gray or silver metal layer, while still being somewhat transparent.

Foam is also available in both pink (differential) and black (conductive), which is used to store lead components separated by perforating pipes into the floor.

 Specifications of antistatic filter bag

• Low temperature resistance
• It is very resistant to hydrolysis, acids and alkalis
• Smooth surface, more defined pore size and good air permeability
• Less fiber secretion, low density, high mechanical properties

Advantages of antistatic filter bag

1. Antistatic dust collection bag is  carefully made and the size is determined for ease of installation.

2. Antistatic filter bags  are designed to collect dust in such a way that you have to put a strong band, cord band, or clamp in place to ensure a firm seal of dust.

3. Various coatings and finishes can be applied on both sides  of the antistatic filter bag  to enhance cleanliness and efficiency as well as extend service life.

4. Ground rings, anti-fall rings and other options can be easily included in the construction  of antistatic filter bags  .

Polyester fibers

Polyester fibers are the most widely used fibers for the production  of antistatic filter bags  . The main feature of these fibers

Proper stability is high abrasion resistance to acids. Among the features of this filter is resistance to solvents and oxidants. During the production process, we can implement countless functional cases on it, one of which includes the application of anti-electricity polyester, which has an anti-static primer.
