Most manufacturers in the production of heat resistant conveyor belt, often encountered with body foaming problem, of course, we are no exception, but we have found the cause of the bubble, and find the solution

Way. Now mainly to talk about the causes of bubbling, hope to provide help to other manufacturers. In general, the common appearance quality defects for three main reasons:

(1) the canvas rolling was not dry or the water is too large. Cotton canvas rolling brush glue, should be dried then spreader frictioning and adhesive plaster. If you have not yet dry, water is too large, then curing water vaporizing

A bubble. EP fabric and nylon fabric without drying, opened after the glue should immediately, in order to avoid exposure to atmospheric moisture absorption, especially in rainy days the air humidity is big, rolling good canvas storage time should not be too long; molding

Should immediately put the cover rubber core zone, which can avoid the wick moisture foaming. Therefore, in the process of forming coated side glue or white coated mortar should be solvent dry glue, glue the wet curing can cause

Bubble.

(2) with a core or rubber covered with debris. In rolling out the procedure, molding process, if the belt core or cover, because the work environment is not clean, or improper operation will sometimes mixed with impurities. At the same time interval

From the cloth not clean enough stick in the debris belt can also cause blistering, so the production of each link in the process should pay attention to the environment clean, well civilized production.

(3) curing plate cylinder cooling water temperature is too high, the control is not good. Plate vulcanizing machine cylinder inlet temperature should be controlled well, can not be too low, too low viscose; more can not be too high, too high cylinder mouth parts easily

Foaming, so the control cylinder temperature is an important content of sulfide workers should pay attention to. Especially the EPDM tape, if the curing time is long, the temperature is too high, membrane when the cylinder mouth blister easily.

Three the above is the main cause of heat resistant conveyor belt foaming, remind you again in, buy a conveyor belt is the note body is formed, it will be very easy to shorten the service life of the conveyor belt. If there are other
