The construction of the runway is very important. As an important project in life, the quality of the construction directly affects the later use effect. PTJ-120 Sprayer Machine manufacturers believe that it is also very important to strengthen the maintenance and protection of the stadium runway roads, so Today, PTJ-120 Sprayer Machine manufacturers talk about the issues that need attention in runway maintenance?
1. For the formed rubber pavement, the PTJ-120 Sprayer Machine manufacturer recommends that it should be covered and watered after the pouring is completed (when the average temperature on the day is lower than 5 °, watering is not allowed).
2. The curing time of watering is as follows: The manufacturer of PTJ-120 Sprayer Machine introduces the concrete made of Portland cement, ordinary Portland cement or slag Portland cement. The curing time should not be less than 7 days; Type admixtures or rubber materials with impermeability requirements, the curing time shall not be less than 14 days;
3. The PTJ-120 Sprayer Machine manufacturer believes that during the curing period, it is advisable to keep the rubber material in a wet state every day with watering. Depending on the environmental conditions such as temperature and air humidity, the curing water should be the same as the mixing water.
4. When the plastic cloth is used for covering and curing, the exposed surface of the rubber material (including the surrounding sides) should be tightly covered with plastic cloth. Condensation should be kept in the plastic cloth.
5. Large-area structures (such as floors, roof panels, etc.) can be stored with water. The manufacturer of PTJ-120 Sprayer Machine introduced that a class of projects such as storage tanks can be filled with water after the inner mold is removed and the concrete has reached a certain strength. Some underground structures or foundations can be painted on the surface instead of watering.
