聚氨酯发泡剂（PU-88）在石油管道应用

Application of PU Foaming Agent （PU- 88 ） on Oil Pipeline

自主创新聚氨酯发泡剂的生物、结构、功能、组装、应用技术，开发了聚氨酯发泡剂（Pu-88）。天然的物质是最好的，我们采用提倡“回归自然”的生产方式，使用天然生物高分子材料，环保、节能、减排、安全、无污染、无毒性，无燃烧爆炸性。用量少，经济效率高，社会效率好。为了保护好大气臭氧层，节能减排，使人类生存环境更舒适更美好，我们的未来必将是绚烂多彩的美好世界。

The independent innovative technology on the biology, structure, function, assembly and application of new polyurethan foaming agent is presented and PU - 88 polyurethan foaming agent is intro- duced. The natural material is the best choice and we advocate the production mode of ＂back to nature＂ and use the natural biological high molecular materials as they feature enviropnmentally friendly, energy conservation, emission reduction, safety, no pollution, no toxicity, and no combustion and no explosion. It enjoys its advantages such as less usage, high economic benefits and perfect social efficiency. It is useful to protect the atmospheric ozone layer, save energy and reduce the emission and it will make the living environment of human beings more comfortable and make our future much better.
