求翻译：添加Na3PO4•12H2O后，聚氨酯硬泡材料的燃烧时间明显缩短，阻燃性能提高，正交试验确定Na3PO4•12H2O添加量4%；Na3PO4•12H2O烘干温度50℃；催化剂辛酸亚锡加入量0.4%；催化剂三亚乙基二胺加入量0.7%时，聚氨酯材料的最高蓄热温度降低了12℃，是最佳添加方案。是什么意思？

Rigid polyurethane foam material to add na3po4 • 12h2o, burning time was significantly shorter, flame-retardant performance, orthogonal experiment to determine na3po4 • 12h2o added 4%; na3po4 the • 12h2o drying temperature of 50 ° C; the catalyst bitterness Ya Xijia intake 0.4% ; catalyst Sanya ethy

Add Na PO 4 •12 3 2 H O, polyurethane rigid foam material of the burn time significantly reduced, flame retardant performance increase, the Q-tests to determine PO Na 3 4 12 2 O H added 4 per cent; Na PO 4 •12 3 2 H O drying temperature 50 °; Catalyst C bitterness to the tin catalyst 0.4 %; 3 in the

Increases Na3PO4•After 12H2O, the polyurethane soaks the material the combustion time to reduce obviously hardly, the being flame-resistant performance enhances, the orthogonal experiment determines Na3PO4•12H2O recruitment 4%; Na3PO4•12H2O drying temperature 50℃; The catalyst bitter divalent tin jo
