摘要

在美国，环境保护局已就推定最大可用控制技术提出了临时建议。其中两种选择--变压发泡（V.P.F.）和液态 C02 喷射工艺--在以下基础上进行了比较：V.P.F. 和液态 C02 均符合《蒙特利尔议定书》的要求。比较结果表明，液态 C02 是解决环境问题的部分方案，而 V.P.F. 则是更全面的方案。

Comparison of the VPF and Liquid C02 Foaming Processes

A number of technologies are now available to replace ozone depleting chemicals and hazardous air pollutants in the manufacture of flexible polyurethane slabstock.In the U.S.A. the Environmental Protection Agency has made provisional recommendations regarding the Presumptive Maximum Available Control Technology. Two of the options - Variable Pressure Foaming (V.P.F.) and the Liquid C02 Injection process are compared on the following basis: Production Range; Economics of Production; Process Improvements; Environmental Considerations; Capital Costs Both V.P.F. and Liquid C02 fulfil the requirements of the Montreal Protocol.The comparisons illustrate that Liquid C02 is a part solution to the Environmental problem, V.P.F. is the more complete solution.

期刊介绍： Cellular Polymers is concerned primarily with the science of foamed materials, the technology and state of the art for processing and fabricating, the engineering techniques and principles of the machines used to produce them economically, and their applications in varied and wide ranging uses where they are making an increasingly valuable contribution. Potential problems for the industry are also covered, including fire performance of materials, CFC-replacement technology, recycling and environmental legislation. Reviews of technical and commercial advances in the manufacturing and application technologies are also included. Cellular Polymers covers these and other related topics and also pays particular attention to the ways in which the science and technology of cellular polymers is being developed throughout the world.
