Analyze the current status of dry-mix mortar production equipment in the current market
现阶段主要存在以下几个方面的问题： As a building material, mortar has a history of thousands of years, but the production method of mortar has continued to use the traditional construction site mixing method. With the development of building technology, the requirements for construction efficiency and building quality continue to increase. The shortcomings of mortar making have gradually emerged. At this stage , dry mortar production equipment mainly has the following problems:
1. Randomness of matching design
Due to the large number of construction teams, the technical level of the construction units varies, often based on experience or borrowing formulas from other sources, the individuality analysis of the raw materials selected by them is insufficient, and the lack of systematic material performance inspection results in low mortar performance, which seriously affects the inherent quality of the material, and further Bring hidden dangers to project quality.
2.Inaccuracy of measurement control
The batching process of most on-site mortars is still at the stage of manual measurement, and the weighing error is very large. As a result, either less gelling material will cause the strength to decrease, or more gelling material will increase the cost. , And because of the shrinkage problem when the gelling material solidifies, cracks occur, which causes huge fluctuations in quality.
3. Heterogeneity of mixed mortar
On-site mixing of mortar is generally performed by manual or small mortar mixers , and uneven mixing often occurs.
4.Low production efficiency
的产能和效率很难有大幅度的提高。 Due to the relatively low degree of mechanization and automation using traditional operation methods, it is difficult to greatly increase the capacity and efficiency of dry-mixed mortar production equipment .
5.Instability of mortar performance
The impact of raw materials on mortar performance is large. Mortars for different uses need to be mixed from corresponding raw materials. However, traditional mortar production methods are limited by raw materials, mechanical equipment and other factors, which can only be caused by material construction, resulting in performance. Uncertainty.
6. Poor environmental protection
During the storage and production of raw materials, pollution sources such as dust, noise, and sewage will form, which will cause different degrees of pollution to the surrounding environment and urban sewage pipe network.
7, low quality, low security
Because there is no scientific empirical mathematical model guidance, the quality of mortar can only be controlled by making test pieces at the same time, and then verifying after the curing age, even if there are problems, it is difficult to make up.
也就应运而生。 The resulting wall cracking, water seepage, color difference, and emptying and falling off of the plaster layer occur from time to time, so the reform of the traditional mortar production method has become one of the urgent tasks in the field of current building materials. As a result, mixed mortar production equipment came into being.
