Base material of polyethylene / carbon black composite material characteristics of PTC
Material differences in Division PTC properties. Figures 6 and 7 combined with easy to see, HDPE crystallinity, crystal integrity, and only when the temperature reaches the melting point. Phase was changed. Therefore, below the melting point, little of resistance change with temperature in the melting point, phase change dogs, which PTC intensity is also large. The branched-chain LDPE as many low crystallinity, crystal phase is not complete. Therefore, the temperature reached the melting point beam, some will not complete phase change in t result is increased system resistance with temperature also increased significantly. Melting point, relatively little change in phase, and thus lower PTC intensity. LLDPE structure in between, but also between the PTC characteristics of the smell. 4.2 Recovering PTC thermal repeatability from Figure 3, Figure 4 and Figure 5 shows the relative HDPE and LLDPEt tLDPE its PTC properties of composite materials have better thermal repeatability. 433 Figure 6 emblem mirror with partial view of seven were split into 3 and PE crystallization deter (a) LDPE (b) LLDPE (c) HDPEoJthreePEypotarlzingmieroscope material has obvious Pr (, properties of materials IIDPE 『t do very sentence.

Pinene thermal cycles in the process of (1) the structural stability of polymer-based material; (2) conductive filler (carbon black) is assumed by the stability of the distribution of the history of United. 3 the structure of polyethylene-based material is relatively stable, NA me, the stability of the distribution of embedded particles is the most critical factor is the carbon particle volume distribution of the boat-like stability, depends on the carbon particle interactions with the polyethylene phase. The stronger, more stable distribution of carbon particles. For LDPE, the molecular abundance of multi-branched chain, dendritic,MAC 120 color eyeshadow, and the molecular chain of HDPE rarely branched, to linear structure, and in order. Therefore, LDPE strong interaction with carbon particles, carbon particles more easily dispersed in LDPE in the \better thermal repeatability. LLDPE cluster j Tho boat in LDPE and HDPE structure between the solid and its thermal repeatability t also intervenes. enhance the stability of this interaction is to improve the pathway in Figure 3, Figure 4 and Figure 5. the first cycle and second cycle PTC characteristics different than where he Fong. is because after the first cycle, eliminating r J-cream inside the material force and uneven bore, base aggregate structure has caused significant changes 5 Conclusion ¨ 3 种 hexene as the base polymer material and carbon black compound time. composite material 1 'references IFrydn ~, nI-1 ¨ nlSl'IlI】 【i ...
