制造钢丝网水泥农船,目前多用手工涂抹成型,也可用机械振压成型和压力喷浆成型。机械振压成型所需设备比较复杂,适于集中生产,不适于分散制作;压力喷浆成型,不易保证船体的密实度及船体壳板的厚度符合规定,同时砂浆损耗也较大。因此,这两种成型方法目前均尚未采用。手工涂抹成型,虽然所需设备简单,能适应船型的多变性,但由于砂浆系用手工在坡度很大的曲面上涂抹,不易严格控制砂浆水灰比,难于保证船体的密实度和强度符合规定,同时对船壳板的厚度也不易控制。为了改进钢丝网水泥农船的成型工艺,我们研究
The manufacture of steel wire mesh cement ships is currently applied by hand, and mechanical vibratory pressure forming and pressure spraying can also be used. The equipment required for mechanical vibratory pressure molding is relatively complex and suitable for centralized production. It is not suitable for dispersion production. Pressure spray molding does not easily ensure that the hull’s compactness and the thickness of the hull plating comply with the regulations, and the loss of mortar is also large. Therefore, these two molding methods have not yet been adopted. Hand-applied molding, although the required equipment is simple, can adapt to the variability of the ship type, but because the mortar is applied manually on a curved surface with a large slope, it is not easy to strictly control the mortar ratio, it is difficult to ensure that the ship’s compactness and strength in line with the provisions At the same time, it is not easy to control the thickness of the hull. In order to improve the molding process of steel mesh cement ship, we studied
