2019-12-20[1] The difference in Mooney viscosity of the elastomer used is too large; [2] Inappropriate selection of plasticizer and rubber; [3] Too much granules; [4] Small partic......
2019-12-19[1] Rubber has expired and is partially gelled; [2] EPDM or butyl rubber is too cold; [3] frozen natural rubber; [4] Insufficient pre-plasticization of natural rubber; &......
2019-12-19[1] Invalidation of temperature control of the internal mixer; [2] Insufficient pressure on the upper plug; [3] Excessive wear of the welding layer in the mixing room; [......
2019-12-19[1] Failure to follow the established mixing process; [2] Aggregates of oily and dry materials stick to the top pin and the side of the feed hopper [3] Improper rotor speed [4] Th......
2019-12-19[1] Insufficient mixing time; [2] Draining temperature is too low or too high; [3] At the same time add acidic and alkaline complexing agents (such as adding stearic acid and scorch inhibitor ESEN t......
2019-12-19A. The main reasons for the agglomeration of the compounding agent are: insufficient raw rubber mastication; excessive roller distance; excessively large rubber loading capacity; excessively high roll......
2019-12-19It is closely related to groups. All rubbers with nitrile (-CN) hydroxyl (-OH) and carboxyl (-COOH) groups have strong polarity, which is called polar rubber. They have good bonding with metals, and r......
2019-12-18Different groups on the rubber monomer bring different characteristics to the rubber. Such as: -COOH (carboxyl): can give good viscosity;-CL: polar and electronegative; phenyl: large volume can block ......
