GRC manufacturers tell you GRC line maintenance methods

GRC line maintenance method:

1 Before and during demoulding

After modification, the mold is usually wrapped with a clean and high-quality polyethylene film, which prevents the evaporation of the water contained in the GRC and is affected by wind, while also helping to maintain the hydration heat. In the early stage of maintenance, GRC products should have sufficient strength so that they will not be damaged during demoulding and handling. At temperatures below 20 ° C, GRC products need to be heated, and steam can be used for heating.

2 Main maintenance

This main maintenance stage is to make the GRC line continue to be protected from the influence of sunlight, wind and low humidity of the air, and in general, the local humidity can be maintained by spraying wet fog.

3 Post maintenance

Protected from direct sunlight during storage. Accelerated curing is effective, including GRC low pressure steam curing and the use of chemical early strength agents.

Low pressure steam maintenance: in cold days, the method is economical for the turnover of the mold, and the temperature should not exceed 50 ° C, otherwise it is unfavorable to long-term strength. The use of chemical early strength agents: this admixture can mainly improve the early strength, is useful in cold conditions, and can make the product earlier release.

Product loading and transportation:

When loading and handling products, they must be carried lightly and throwing is strictly prohibited. Transport should be fixed firmly, to prevent the GRC line shaking, if necessary in the products with straw MATS separated, products placed shall not exceed the length of the carriage.
