早在60年代初期,我们在新乡化纤厂工地曾把菱镁制品代木制成门窗框用于建筑上,但由于制品脆性大,经不起门窗扇的反复启闭运动,导致合页脱落而未被推广。现在提出把菱镁制品用于制作机械装箱,其用途虽不同,但应考虑的共性问题只有一个,那就是菱镁制品的脆性。这个脆性在装箱中会出现于受弯与受压部位,尤以前者为甚。故当机械装入后,在运输、卸车过程中,箱
As early as the early 1960s, we had used mahogany products as a door and window frame on the construction site of the Xinxiang Chemical Fibre Plant. However, due to the fragility of the products, they could not withstand the repeated opening and closing motions of the door and window sashes, causing the hinges to fall off. Not promoted. It is now proposed to use the magnesite products for mechanical packing. Although their use is different, there is only one common problem that should be considered. That is the brittleness of magnesite products. This brittleness appears in the flexure and compression areas during packing, especially in the former. Therefore, when the machine is loaded, the box is transported and unloaded.
