一种新型氚防护服面料制备及性能研究
Preparation and performance study of a new type of tritium protective clothing fabric
摘要
Abstract
This paper designs and develops a new type of tritium protective clothing fabric—a PVC/EVA/PVDC/EVA/PVC composite fabric.This fabric uses PVDC,which has excellent tritium barrier properties,as the functional layer,EVA as the transition layer due to its high thermal compatibility with PVDC,and PVC as the outer layer for its superior processing performance.The fabric is manufactured using co-extrusion and bonding processes.The new fabric has excellent water vapor barrier properties,with its water vapor transmission being only 1/7.3 of times that of radioactive contamination protective clothing fabric(0.20 mm PVC).Studies on the barrier performance of fabric seams show that seams made by bonding and high-frequency thermal sealing processes have better barrier properties than seamless materials,with the main penetration path being vertical penetration.Tests on the mechanical properties and softness of the new fabric indicate that its abrasion resistance,flexural damage resistance,puncture resistance,tear resistance,and softness all meet usage requirements,with the flexural damage resistance and tear resistance significantly exceeding standard requirements.关键词
