How to better maintain the quality of concrete pipes during the production process is a concern for many manufacturers. Today, XiaoHere are a few points summarized for you:

Knowledge Point 1: Pre-De-molding Preparation

During the peak temperature rise period of cement products, the products are experiencing intense heat, and it is not advisable to remove the molds at this time. We must wait until the cement products naturally cool down.The body temperature must drop to 40℃ before the film can be removed. If the environmental temperature for the production of cement products is below 10℃, then we must wait until it dropsRemove the film after room temperature, to prevent concrete products from cracking.

   Knowledge Point 2: Peel Film Maintenance

After the cement products have been molded for 24 hours, the demolding process should be conducted 12 hours later, and it must be done within 8 hours of the cement products' shaping.Can be de-molded. If the temperature of the cement products differs by more than 20℃ from the ambient temperature, do not use accelerators or heat to accelerate the setting to avoid producing poor-quality cement products.After demolding, cement products must be insulated. After controlling moisture and timely demolding, they also require continued maintenance. Cement products cannot be sprinkled with water after demolding.Moisture or bubble preservation methods for maintenance, film, damp cloth, and wet reed curtain covering techniques.

Knowledge Point 3: Arrangement

Do not use steam curing, autoclave curing, or hot-press molding to ensure the strength and other properties of cement products. Remove the mold from the cement products.Stack neatly, strictly prohibited from placement on uneven surfaces. Especially ensure stable positioning for irregularly shaped products.
