compacting pressure 中文意思是什麼
-
Experimental study on the lateral pressure coefficient of friable rock during compacting
鬆散巖塊側壓系數的試驗研究 -
Powder metal is often used instead because it is undesirable or impractical to join the elements through alloying or to produce parts by casting or other forming consists of producing small particles, compacting, and sintering. the squeezing pressure with added heat bonds the metal powder into a strong solid. powdered metals can be ferrous, nonferrous or a combination of ferrous and nonferrous elements
金屬合金一般是無孔隙固體；因為煉制出的合金的實際效果不理想，或者通過鑄造和其他成型方式對小的顆粒進行壓制，燒結出來的產品零件無法滿足需求，因而人們常常使用粉末金屬來代替金屬合金。 -
The optimum conditions for air electrode preparation were shown as follows : active carbon which was baked for 15 min in 900 as carrier for catalyst, bond is 60mass % polytetrafluoroethylene ( ptfe ) liquor, 20 % ptfe in waterproof layer, 10mass % pore - making in waterproof layer thickness of waterproof layer 0. 30mm, 10mass % ptfe in catalysis layer, nickel screen for current collector, compacting pressure 6mpa
確定製備空氣電極的最佳工藝條件為:催化劑載體的處理條件為在900下灼燒15min ，粘結劑為60mass % ptfe的水溶液。防水層中pefe含量為20mass % ，造孔劑含量為10mass % ，其厚度為0 . 3mm 。催化層中ptfe含量為10mass % 。 -
