Influence of Material Properties on Service Life of Sealers
The material properties has direct influence on the sealing effect.This paper expatiates the influence of material properties,including anti-friction,stability,technicality and economy,on the sealer's service life.
Abstract The feasibility of using a silicone rubber membrane to separate mixtures of isopropyl alcohol and water, including the azeotropic composition, has been demonstrated and a quantitative measure of efficiency of separation has been developed. One of the problem areas in studying liquid permeation is the variability in the polymer membrane structure. Such factors as the presence of solvents and plasticizers, previous thermal history, previous solvent history, and the degree of crystallinity of the polymer behavior affect membrane behavior. However, as the polymers are better understood, these drawbacks for the researcher may be of advantage to those tailoring a polymer to a specific use.
