PROCEDURE FOR CLEANING A RUBBER BELT

 

A general cleaning of any Rubber Belt (RB) is advised periodically for the following reasons:

 

To remove any chemical build-up (e.g., finish, resins, sizing, color, etc.) that, if left on the surface, would degrade the rubber and lower its durometer, necessitating shorter grinding intervals.
To aid the RB in its ability to recoil and smoothly slip against the steam cylinder. A build-up of material on the RB face and/or steam cylinder may prevent this from occurring.
To relieve surface tension on the belt's face, particularly after grinding. Otherwise, the cooling water may not adhere as well to the face of the belt. This, in turn, may affect the belt's ability to successfully process certain fabrics.
To aid general housecleaning and inspection procedures. Through vigilant care the RB will last longer. Use this time to thoroughly inspect the RB for any tell tale signs of trouble, e.g., cracking, uneven or low durometer readings, tacky surface, resin build-up on the selvages, etc., and resolve any problems found while still young and, hopefully, insignificant.
As a safety precaution. Cleanliness promotes safety.

(Note: The cleaning frequency will vary depending upon many variables. The spectrum is daily to quarterly, sometimes less. Our advice is to wash more often than not enough. Experience is the best guide).

PROCEDURE

Substantially cool the steam cylinder from its operating temperature or start with a completely cold cylinder. (Note: This is to prevent potential damage from occurring to both the RB and steam cylinder).
The compression roll should be set to "0" (no compression) and the water removal rolls open. (Note: It may become necessary to apply a small amount of compression to prevent the RB from slipping against the steam cylinder, but it should remain minimal).
Turn on both the inside and outside water pipes. Turn the RB approximately (5-10) meters per minute while both surfaces become wet.
Continue rotating the RB, but turn the water flow down to a minimum, both inside and out. This is done so the soap, applied next, is not prematurely removed.
Sprinkle some non-chlorinated soap, e.g., Borax, (Rubber Belt Maintenance Products) on the inside and outside surface until uniformly covered.
Turn off all water, allowing the RB to continue turning at (5-10) meters per minute.
As the RB turns, the soap/water mixture will begin to foam.
During this period, remove any stubborn chemical build-ups from the steam cylinder using a copper sponge or scraper. Copper should be used so as not to damage the steam cylinder.
Depending on the severity of the chemical build-up, it is usually sufficient to turn on the water sprays after (10-15) minutes. The water will then flush the loose chemicals, soap, etc., from the RB and steam cylinder surfaces. In extreme cases, it may be necessary to repeat this procedure and/or use a medium-stiff bristle brush to successfully clean either surface.

            Assuming a correct durometer and the removal of any blemishes, the RB should now be ready for production.
