compacting conditions 中文意思是什麼
-
The reduced minimum cement contents shall only be used when trial mixes have verified that concrete with a maximum free water / cement ratio not greater than that given for a particular condition can be consistently produced and it is suitable for the conditions of placing and compacting
只有經過試拌證實，可以持續不斷地生產出最大水灰比不大於某一特定工況給定值的混凝土，而且這種混凝土適合於攤鋪與夯實，在這種情況下，才可以使用這一縮減的最低水泥用量。 -
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 % 。
