Separating glued PVC pipe is challenging due to the chemical bond formed by the solvent glue, which essentially "welds" the pipe and fitting together. However, if disassembly is necessary, consider these methods: **Cutting and replacing** is the most straightforward approach, using a hacksaw or PVC cutter to remove the glued section and then installing a new pipe/fitting. **Heating** is another method, where applying controlled heat with a heat gun might soften the glue for separation, but this carries a risk of damaging the PVC if overheated. Lastly, there are **commercial PVC ungluing agents**, designed to dissolve the solvent weld, although their effectiveness may vary. Note that in many cases, cutting out the glued section and replacing it is the most reliable solution.

As of my last update in 2023, I cannot provide real-time current prices for polypropylene due to the dynamic nature of commodity markets. However, polypropylene prices are influenced by several factors, including crude oil prices (as polypropylene is a petroleum derivative), demand in consumer goods and automotive industries, and global supply chain conditions. Typical fluctuations are seen in response to changes in these areas. For current prices, it's best to consult a reliable financial news source or commodities market update. Additionally, subscribing to industry-specific newsletters or market analysis reports can provide regular updates and insights into price trends, helping businesses and consumers make informed decisions.

Yarn care symbols provide essential guidelines for washing, drying, ironing, and bleaching yarns or yarn-made items, helping maintain their quality over time. Each symbol represents a specific care instruction: a tub icon signifies washing conditions, with dots indicating temperature and lines beneath for recommended washing cycle strength. The triangle symbolizes bleaching instructions, where a plain triangle permits it, and a crossed-out one means bleach is not allowed. Ironing symbols look like an iron, with dots reflecting the maximum temperature allowed for ironing. For drying, the square icon is used; lines inside dictate whether flat or line drying is suggested, and circles inside indicate tumble drying conditions. Understanding these symbols is vital for preserving the texture, color, and structure of yarn crafts. It's advisable to always check the yarn label for these symbols before washing or caring for your yarn items, ensuring they stay beautiful and intact for as long as possible.
