There are many familiar building materials in the decoration process. For example, cement is a kind of building material that we are very familiar with, and its application range is very wide. For the use of cement, the proportion must be appropriate before use. So the proportion of polypropylene rubber powder and cement is very common. But many people are not familiar with polypropylene rubber powder and don't know how to mix it with cement. Then, residential online will explain how polypropylene rubber powder and cement are matched.
1. How does polypropylene rubber powder mix with cement?
The so-called polypropylene rubber powder is actually a very professional rubber powder for bonding polypropylene cloth, which can be mixed with cement in a certain proportion to achieve a good bonding effect. Polypropylene rubber powder is a refined polymer material. Generally, polypropylene rubber powder with good quality is tasteless, nontoxic and non-irritating. It can be quickly dissolved in water, and can quickly form a transparent solution, which reacts with cement to enhance the strength and viscosity of cement. However, the specific ratio of polypropylene rubber powder to cement needs to be determined according to the thickness of cement mortar layer, so the ratio will be different. Generally speaking, if you use one kilogram of polypropylene rubber powder, you need to prepare two bags of cement. Generally, the weight of each bag of cement is 50 kg, which means that one kilogram of rubber powder needs to be mixed with 100 kg of cement, which is the most suitable viscosity.
Second, what should be paid attention to in the construction of polypropylene rubber powder?
1. Design or construction standards shall meet certain standard requirements.
2. Before the completion of polypropylene rubber powder, it is necessary to formulate a certain completion plan, review drawings, understand certain design intentions, and formulate a waterproof project construction plan.
3. If polypropylene rubber powder construction is needed, the waterproof layer should avoid bad weather and rainy days, and the protective layer of the waterproof layer should be formulated according to the engineering design.
4. The proportion of polypropylene rubber powder binder needs to adjust the concentration of binder according to the wet and dry conditions of the substrate.
5. The humidity range of polypropylene rubber powder should be between 0 and 30 degrees. If it exceeds the specified humidity range, special insulation or cooling measures must be taken.
