Awọn iru ẹrọ meji, ga-iyara aladapo ati simenti aladapo, ti wa ni lilo fun ṣiṣe foomu pẹlu ga-iyara aladapo abẹfẹlẹ.Firstly, ojutu oluranlowo foomu ti a pese sile ni ibamu si iwọn kan ti wa ni afikun si alapọpo iyara-giga, ati pe a ti pese foomu precast labẹ iyara iyara ti abẹfẹlẹ naa.Fọmu ti o yọrisi lẹhinna ni a da sinu aladapọ simenti lati yọ ration naa kuro., foomu ati slurry ti wa ni adalu lati ṣe cellular concrete.The ọna ti ṣiṣe foomu pẹlu ga-iyara saropo abẹfẹlẹ ni o rọrun ati ki o reproducible, eyi ti o le ṣe afihan awọn ohun-ini ifofo ti aṣoju ifofo.Sibẹsibẹ, due to uneven size of the upper and lower bubbles, a gauge is needed in the process of pouring the foam into the cement mixer, and the foam burst will inevitably occur, resulting in waste.
Compressed air foam method, which is mainly made of special foam cylinder this key equipment.The compressed air is mixed with the foaming agent solution in the special equipment, and the resulting foam is exhaled from the bubble cylinder through the compressed air. Níkẹyìn, the produced foam is transferred to the cement mixer for mixing, and then the cellular concrete is made.Foamed tube internal materials available for use are magnetic disk, glass ball, copper and so on.
Combining with the using of foreign legal system of compressed air and the domestic high-speed stirring blades dip process, according to the characteristics of two different after comparison found that the legal system of compressed air foam equipment used, though a bit complicated, but the legal system of compressed air foam advantage is high speed mixing blade bubble method cannot reach, it effectively prevents the foam waste phenomenon.On the one hand, there is no uneven diameter of foam produced by compressed air after passing through the foam cylinder.On the other hand, the foam made is blown directly into the cement slurry, reducing the intermediate flow process;Jubẹlọ, slurry mixing and foaming are carried out simultaneously, so quantitative foaming can avoid the problem of excessive foaming.
2 Preparation technology
There are two methods of preparing cellular concrete: pre-foaming method and mixed foaming method.
