1、 Price trendAccording to the monitoring data of the toodudu, the price of caustic soda went down. At the beginning of last week, the average market price in Shandong was about 1272 RMB/ton. At the end of last week, the average market price in Shandong was 1250 RMB/ton. The price fell by 1.73%, and the price increased by 159.07% compared with the same period last year.2、 Market analysisAccording to the survey data of toodudu, the price of domestic caustic soda fell this week. The price of caustic soda in Shandong has been lowered slightly. The average market price in Shandong is about 1150-1250 RMB/ton. The mainstream ex factory quotation of 32% liquid caustic soda in Hebei is about 1200-1400 RMB/ton. The supply of enterprises is relatively stable. After the price of caustic soda has been lowered, downstream enterprises mainly take a wait-and-see attitude. There is little change in the overall trading of the market. The inventory of alumina manufacturers is high, there is a heavy wait...

Q how to keep pvc glue from drying out

To keep PVC pipe from bending, several strategies can be implemented. First, selecting the correct thickness or schedule of PVC is crucial; thicker pipes are less prone to bending. Use Schedule 40 or 80 for applications requiring structural strength. Second, provide adequate support along the pipe’s length. This can include installing support brackets or a frame that holds the pipe firmly in place at regular intervals. Third, consider using a PVC insert, especially for longer spans of pipe; a wooden dowel or metal rod inserted into the pipe can significantly increase its rigidity and resistance to bending. Also, avoid exposing PVC pipes to excessive heat, as high temperatures can soften the material, making it more susceptible to deformation. Lastly, for critical applications, consider using pipe made from more rigid materials or reinforced PVC to ensure maximum stability and prevent bending.

Q can you paint pvc

Yes, you can paint PVC, but preparation is key to ensure good adhesion and a lasting finish. PVC surfaces are non-porous and slick, which makes them challenging for paint to adhere to. Start by cleaning the PVC with a solution of water and mild detergent to remove any grime or grease. After drying, lightly sanding the surface with fine-grit sandpaper can help create a texture for the paint to grip onto. Applying a primer designed for use on plastic surfaces is crucial; it provides a suitable surface for the paint to adhere to. Once the primer is dry, you can apply acrylic or latex-based paint, preferably with a spray for a smooth finish. Multiple thin coats are recommended for the best results. Always allow ample drying time between coats.

Q connect pvc pipes together

The cure time for PVC cement varies based on the product and environmental conditions but typically ranges between 15 minutes for initial set-up to 48 hours for full-strength bonding. PVC cement works by chemically fusing the PVC pipes and fittings together, so ensuring sufficient cure time is crucial for a reliable seal and pressure resistance. The temperature and humidity levels can significantly affect the cure time; warmer and more humid conditions can accelerate the curing process, while cooler or drier conditions can extend it. It’s essential to check the manufacturer’s instructions for specific cure times and recommendations. For projects under pressure systems, a minimum of 24 hours cure time is often advised before testing the system. Ensuring proper cure time is not only about the bond’s strength but also about safety, especially in potable water and gas applications.
