STAT - conductive

STAT - conductive Product Fact sheet

Some bulk materials can create static energy during filling and discharging, which may cause an electrostatic discharge in the bag or on its surface. If, there is a flammable dust or gas present within the atmosphere during the filling and discharging process, there is a risk of fire or explosion. To prevent this hazard, a groundable FIBC’s is the ideal solution. Groundable FIBC’s are also classed as Type C bags.

The conductivity of these units is usually provided by carbon tapes which are woven into the fabric and the webbing. Silver tapes are used instead of carbon for food applications. The body construction of the FIBC can be produced out of a flat or circular fabric either coated or uncoated. Conductive liners are also available for use if waterproof applications are required. Type C FIBC’s must be grounded during the filling and discharging process and every groundable bag produced is 100% checked and labelled accordingly for its conductivity.

Today, type D bags have become more familiar to the groundable bag users, as a challenging alternative for Type C bags.

The usage of Type D bags are much more practical than the groundable bags and they avoid operator errors. The special construction of the Type D fabric eliminates the need of an earth connection during the filling and discharging of materials.

Crohmiq® is the first true Type D fabric to appear in the market place since the early 1990’s. The fabric was developed to cover a growing need for an ungrounded static protective solution for bulk packaging.

Due to its reputable safety record, as of today, over 500 leading companies worldwide prefer FIBCs manufactured from Crohmiq® fabric for their static bulk bag packaging requirements.

Today Crohmiq® is the only Type D fabric in the market which complies with the IEC standards.

Why type D?

• Unlike Type C FIBC's, Type D FIBC's do not require grounding.
• Can be used for the transportation of flammable powders, or when flammable solvents or gases are present around the FIBC.
• It provides safety equal to a grounded Type C FIBC without the human error risk factor.
• Type D fabric permits the dissipation of the charges in to the atmosphere by corona discharge.
• A corona discharge is one form of an electrostatic discharge with a low energy, unlike sparks or brush discharges, it does not give way to ignition of flammable or explosive atmospheres.

Why crohmiq?

• Only CROHMIQ® 's patented technology provides a level of safety equal to a properly grounded Type C FIBC, but without the risks of human error. For these reasons, leading global companies continue to switch from Type C FIBC to the optimum safety of CROHMIQ® FIBC.
• CROHMIQ® 's properties are permanent, therefore, its static dissipative performance does not decay with time nor wash off during wet reconditioning processes as many pseudo Type D FIBC's do.
• CROHMIQ® fabric is FDA compliant.
• Internationally recognised as the leading Type D static protective FIBC fabric.
• It is the only Type D fabric that will comply to the IEC61340 - 4 - 4 : 2005 standards.

Warnings:

If the surface of the Type D FIBC is contaminated or coated by any conductive material (such as water, oil etc) then spark discharges may occur.

Therefore

Precautions should be taken in order to prevent the surface contamination. No conductive object (such as metal items and tools) should be placed on the FIBC. All conductors in the presence of flammable or explosive atmospheres should be grounded.
