Stat - Conductible

STAT - Conductible Fiche produit

Certains produits vrac peuvent créer de l’électricité statique pendant le remplissage ou la vidange, qui peut provoquer une décharge électrostatique dans le sac ou à sa surface. En présence de poussière ou gaz inflammables dans l’atmosphère pendant les opérations de remplissage ou vidange, il y a risque de feu ou d’explosion. Afin de prévenir ce risque, la solution idéale est un GRVS conductible, communément nommé TYPE C.

La conductibilité est en général obtenue par des fils de carbone tissés dans la toile et les sangles. Des fils d’argent sont utilisés pour une application alimentaire. Le GRVS peut être construit à partir d’une toile à plat ou circulaire, laminée ou nue. Une doublure conductible peut également être insérée si nécessaire. Les GRVS TYPE C doivent être connectés à la terre pendant les opérations de remplissage et vidange. La conductibilité de chaque sac est contrôlée en fin de production, et les sacs étiquetés individuellement.

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.


Safe use of different FIBC types
