Roller lagging Belt machine drum lagging
There are currently two main forms of drum lagging in China, one is hot vulcanization lagging, and the other is cold lagging. Drum cold lagging is the more popular drum lagging at present. method, but whether the cold lagging of the roller is good or bad is determined by many factors. Industrial and mining enterprises must choose carefully when choosing
At present, there are several modes of cold lagging of the roller
,
Hot vulcanized adhesive semi-vulcanized layer of imported wear-resistant rubber sheets. The cold vulcanized adhesive is a hot vulcanized agent imported from Germany as the main representative product. Therefore, the glue and layer Wear-resistant rubber sheets are known for their ability to react chemically. Imported wear-resistant rubber sheets have been praised by many industrial and mining enterprises due to their excellent wear resistance, simple and fast operation. This roller cold lagging method is currently the most durable, has a long service life, and has good effects.
,
Hot vulcanization adhesive domestic rubber sheet This roller lagging method is not allowed within the technical scope of German standards, because
Hot vulcanization
Adhesives and rubber cannot react chemically, and domestic rubber sheets do not have a semi-vulcanized layer. Such combination bonding is only the adhesive force of the glue itself, which reduces the overall bonding effect of the roller lagging and its service life. Short, it is easy for the rubber plate to fall off.
, cold adhesive domestic rubber sheet, this drum encapsulation method is an economical encapsulation method in the drum cold encapsulation method, but it is also not suitable for the drum cold encapsulation construction mode. Durable, mainly due to the uneven quality of domestic rubber sheets. There is no unified standard for the rubber sheets used for roller lagging in China, and the bonding strength of the cold adhesive is not strong, causing the rubber sheets to fall off easily. Opening glue, etc.
