發(fā)布時間:2018-11-10 22:53
【摘要】:以國家知識產權局公布的中國專利數據庫為數據源,設定關鍵詞進行檢索,分析國內公開的磷酸銨鹽滅火劑專利的申請趨勢、申請人、技術領域、專利法律狀態(tài)等,揭示磷酸銨鹽滅火劑的競爭態(tài)勢及發(fā)展方向。對比美國專利數據庫、歐洲專利數據庫、德溫特專利數據庫、日本特許廳公布的專利信息,重點對磷酸銨鹽滅火劑的構成成分進行研究。磷酸銨鹽滅火劑的研究正在向改變主要原料、改變產品粒度的方向發(fā)展。
[Abstract]:Taking the Chinese patent database published by the State intellectual property Office as the data source, setting key words for retrieval, analyzing the application trend, applicants, technical fields, patent legal status, etc., of the open domestic ammonium phosphate fire extinguishing agent, The competition situation and development direction of ammonium phosphate fire extinguishing agent are revealed. Comparing with the patent database of USA, Europe, Derwent, and the patent information published by the Japan franchise Agency, the composition of ammonium phosphate extinguishing agent is studied. The research of ammonium phosphate fire extinguishing agent is developing towards changing the main raw material and changing the particle size of the product.
