蒸压养护后为什么会出现裂纹?

在蒸压养护后会因为水料比的原因出现裂纹问题,导致在蒸压养护后出现裂纹的还有其他方面的原因,只有它的安全性得到保障才能更好的为广大用户做好服务,也为厂家带来更宽阔的市场。
  
蒸压浇注温度过高:容易引起成型后期坯体产生裂纹,这类裂纹主要发生在模具中部热量集中的部位;
Autoclaved pouring temperature is too high: the latter body prone to cracks forming such cracks occurred in the middle of the heat concentrated mold parts;  
蒸压配合比中:常由于石灰等钙质材料使用过多而引起坯体总的发热量过大、坯体过早失去流动性,从而造成裂纹,这类裂纹基本类似于水料比过小和浇注温度过高造成的裂纹;
Mix in autoclaved: often due to excessive use of lime and other calcareous materials caused by excessive total body heat, body premature loss of mobility, resulting in cracks, crack such basic material similar to water ratio is too small and cracks caused by the pouring temperature is too high;
坯体的停放环境也是造成坯体裂纹的一大因素:其原因主要为环境温度和湿度过低,使坯体周围因温度差或快速失水造成裂纹,这也是制品缺棱掉角的原因之一。
Body of the park environment is also a major cause body cracks factors: The main reason for the ambient temperature and humidity is too low, so that the temperature around the body due to dehydration caused by poor or rapid crack, which is product missing edge off angle reasons one.  
还有与蒸压养护没有直接关系的,如负压吊的吊运破坏,翻转裂纹,发气时憋气裂纹等。都已在前面作了讨论。值得提出的是,裂纹的反面就是粘连。因此,必须综合考虑各种因素,从多方面入手,寻找合适的平衡点,实现生产质量目标。
There is no direct relationship with the autoclave curing, such as the destruction of vacuum lifting crane, flip crack, crack breath when fat gas. Have been discussed in front. It is noteworthy that the crack is the opposite of adhesions. Therefore, we must consider a variety of factors, from a multi-pronged approach, finding the right balance, production quality objectives.  
当蒸压养护操作不规范时解决方法:抽真空。及时放冷凝水。保证恒温温度和时间。
