Curing steps, post-treatment

How can we minimize the damage to the environment Common sense says that prevention is better than cure. If one can use an environmentally friendly solvent in the processing step, the discharge of hazardous chemicals and the need for environmental post-treatment can be avoided. This is an approach that is currently being explored in polymer processing as well as in other manufacturing technologies (DeSimone et al. 1994). In the case of the... 

Mechanical loss also varies with the cord construction variables such as denier per yarn strand, number of strands and number of twists per unit length ( 2 ). Significant changes In mechanical loss are also observed during the post treatments of grelge tire cords. These Include the steps of cord ten-slllzatlon, application of the adhesives and curing of tires. 

Excellent transport characteristics, solubilization power, and sensitivity to process variables all contribute to the success of the methodology. The generic scheme involves homogenization, impregnation, deposition, and optional post treatment steps such as curing reactions. The mechanism of transport in the porous matrix is permeation and diffusion while the primary mechanisms for deposition are pressure reduction, temperature swing, sorption, and reaction (i.e., polymerization).

Finally, it was deduced that the crossUnking mechanism for aliphatic and aromatic containing amine and diamine was slightly the same and took place in three steps. Aliphatic diamines are more reactive than aliphatic amines and the most used diamine is HMDA-C and its derivatives (N,N -dicinnamyfidene-l,6-hexanediamine and bis-peroxycarbamates). During the post-cure treatment, two different mechanisms of bond making and bond breaking were evidenced, as explained in Sect. 3.1.4.
