目前混凝土预制窗框在轻纺工业的锯齿形车间应用量较大,给预制窗框玻璃的安装带来了困难。市场上出售的商品油灰附着力不强,在短期内出现严重的开裂,不久便起翘和剥落。为了克服上述缺陷,我公司试制了一种新的嵌玻璃专用灰膏。经过几项工程的试用,效果较好。这种专用灰膏具有无臭、无毒、耐寒、耐热、耐老化以及附着力强的优点,而且操作方便、安全,材料来源广,比普通油灰材料降低成本64％。一、材料配比混凝土预制窗框专用玻璃灰膏的材料为325号或425号普通水泥、大白粉、木屑、水、107胶。其配合比(重量比)为水泥:大白
At present, the application of prefabricated concrete window frames in the sawtooth workshop of the textile industry is relatively large, which has brought difficulties to the installation of prefabricated window frames. The putty of merchandise sold on the market is not strong enough to adhere to, and there will be severe cracking in a short period of time. It will start to curl and peel off soon. In order to overcome the above defects, our company has trial-produced a new special paste for glass inlays. After several trials of the project, the effect is good. This special plaster has the advantages of odorless, non-toxic, cold-resistant, heat-resistant, aging-resistant, and strong adhesion. Moreover, it is easy to operate, safe, and has a wide source of materials, which reduces the cost by 64% compared with ordinary putty materials. First, the material ratio Concrete prefabricated window frame special glass plaster materials for the 325 or 425 ordinary cement, white powder, sawdust, water, 107 glue. Its mix ratio (weight ratio) is cement: big white
