Paraffin oil (150﹟)	5
Total	108

Waste IIR Curing Bladder and Curing Bag Reclaiming Technique：

(1) First cut the bladder (curing bag) into large pieces about 15cm×20cm, then cut into particles about 10mm with knife breakdown mill ; as the IIR is easy to be heat and sticky, it is better to cut with water-cooled knife breakdown mill.

(2）Coarsely mill the 10mm particles 3-5 times on the open mill (the roll pitch of the open mill is 1.0mm—2.0mm), when it begins to sheet, add reclaiming agent RDS-IIR(II) and 5 parts by weight of paraffin oil, and continue to mill until it becomes even(about 5-10 times) and get down the open mill.

(3) Mill run 3 times on the second open mill (the roll pitch is 0.6mm—1.0mm) and get down the open mill.

(4) Refine twice on the refining mill (the roll pitch is 0.3mm—0.8mm) and sheet.

Note: The roll temperature of the open mill should be 60℃-70℃. The roll temperature of the refining mill should be below 90℃.

 

RDS-IIR(II) IIR curing bladder and curing bag reviving agent can also be used when the internal mixer is at high temperature
