title: [On analysis of interrelation of the composition, structure and crack problem of plastics slice material].
abstract: In this paper, we analyse the composition, structure and property of two kinds of slice materials by FTIR spectrometer, X-ray fluorometer and tension test device. Results show that: 1) K thin slice consists of PVC resin, plasticizer(15.5%) and a little additive. Its structures look like woollen blanket. Its property is good. 2) L thin slice consists of PVC resin, the plasticier (13.2%), CaCO3 (6.59%) and little additive. There is a little crack on its structure. On these bases, the rupture problem of thin slice is discussed by the theory of the freedom volume and of the boundary chemistry. Research shows that the keys to question are the composition of the thin slices and the quantity of plasticizer.
