丙凝是以丙烯酰胺为主体的一种化学灌浆材料,由于近年来广泛应用于水电、石油、交通、煤炭、冶金,国防等工程中的防渗和堵漏,需要量日益增加,面目前国内仅有几个厂家生产,因此供不应求。为了满足水利电力建设的需要,丹江口管理局化工厂从去年开始批量生产这种化灌材料,今年质量大有提高。为了对该厂产品进行鉴定,丹江口水利枢纽管理局受水电部科技委和基建司的委托,于1978年11月26日至
Propane condensate is a kind of chemical grouting material based on acrylamide. Due to its wide application in seepage prevention and plugging in hydropower, petroleum, transportation, coal, metallurgy, national defense and other projects in recent years, its requirement is increasing day by day. Currently, Only a few manufacturers, so in short supply. In order to meet the needs of water conservancy and power construction, Danjiangkou Authority chemical plant began mass production of this irrigation material last year, this year the quality has greatly improved. In order to identify the plant products, Danjiangkou Water Conservancy Authority commissioned by the Ministry of Science and Infrastructure and Infrastructure Commission commissioned on November 26, 1978 to
