Performance and Causes of Insufficient Floor Strength of Double-Propyl Polyurethane Sealant
- 2019-05-09-

Because of the good wear resistance, anti-seepage, application of gloss and easy construction, the double-propylene polyurethane sealing floor is deeply loved by the construction workers and is widely used in food factories, beverage factories, warehouses, machinery workshops. Printing workshops and other places. However, there will be a series of problems in the construction process, such as lack of strength, what is the lack of strength of the double-propylene polyurethane sealant, and what kind of reason is caused?

Double propylene polyurethane sealant floor strength lack performance

1. Reduce the structural strength and straight fall.

2. The deformation of the component is too large to affect the normal operation.

3. Poor crack resistance and a large number of wide cracks.

Then, directly inducing the landing of its impermeability, the durability will be greatly reduced, and it will affect the bearing capacity of the structure.

What is the reason for the lack of strength of the double-propylene polyurethane sealant floor? The analysis of the construction experts in Zhengzhou pointed out that the main reason is that the concrete mix ratio is not good and the quality of the original data is poor. In detail:

Improper concrete mix ratio

1. Inadequate measurement of sand and stone and lack of cement.

2. Improper use of admixtures.

3. Feel free to apply the mix.

4. The amount of admixture is not accurate.

5. Increased water consumption: It is more common to install water on the mixer and the metering is not allowed; the water content in sand and stone is not deducted; and water is added in the watering place.

Poor quality of original data

1. Abnormal quality of aggregate (sand, stone): low stone strength; poor stone volume stability; poor stone shape and appearance; high content of organic impurities in sand and stone, high dust content, high mica content in sand.

2. The quality of the admixture is unqualified or the composition ratio is unqualified.

3. Poor cement quality: cement stability is unqualified; cement practice activity is low.

4. The quality of the mixed water is unqualified. Rate, because email and chat only require very low bandwidth.
