Another essential chemical in sewage treatment is alum, or aluminum sulfate. Alum is a coagulant used in the primary treatment phase to facilitate the removal of suspended solids and colloidal particles. By causing these particles to clump together, or coagulate, alum aids in their subsequent removal through sedimentation. This is particularly important in reducing the turbidity of wastewater, thus improving the efficiency of subsequent treatment processes. The addition of alum not only enhances removal rates but also aids in the stabilization of organic matter.

Innovations in Biodegradable Additives for Plastics

1. Stabilizers One of the most critical functions of additives in plastics is to protect the material from degradation due to exposure to environmental factors, such as heat, light, and oxygen. Stabilizers, such as antioxidants, UV stabilizers, and thermal stabilizers, are incorporated into plastic formulations to extend their lifespan. For example, ultraviolet (UV) stabilizers prevent discoloration and brittleness that can occur when plastics are exposed to sunlight.


Manufacturing of APIs


Ammonium thiocyanate can be synthesized through various methods. A common route is the reaction between ammonium sulfate and sodium thiocyanate. Another method involves the reaction of ammonium carbonate with carbon disulfide, producing both ammonium thiocyanate and ammonium sulfide. The production process can be optimized based on the desired purity and application requirements.


1. Primary Anti-Static Additives These are often surfactants or conductive polymers that provide immediate anti-static effects by forming a conductive layer on the surface of the plastic. They reduce surface resistivity and dissipate electrostatic charges effectively. Common primary agents include ethylene glycol, glycerol, and quaternary ammonium compounds, which can be mixed with polymers during the manufacturing process.

  • Lock sewing is much more than just a simple technique; it is an essential skill that every sewist should master. Its blend of strength, aesthetic appeal, and versatility makes it a staple in the fabric of sewing artistry. Whether you are sewing a pair of trousers, crafting a quilt, or upholstering a chair, understanding and utilizing lock sewing will undoubtedly enhance your projects. Embracing this technique can elevate your sewing repertoire, allowing you to create durable and beautifully finished pieces that stand the test of time. So, pick up your sewing machine, thread your needles, and let the art of lock sewing empower your creative endeavors!


  • At the heart of long arm sewing is the long arm quilting machine, which typically features a large table or frame and a specialized sewing mechanism. Unlike standard sewing machines, long arm machines allow for the movement of the fabric while the sewing head remains stationary, or vice versa, depending on the design. This setup gives users the ability to quilt large quilts without the struggle of maneuvering tons of fabric through the small throat space of a regular machine.


  • Preparation is key to successful sewing. It is essential to properly align the fabric and ensure that both needles enter the material at the right points. This can be achieved by using pins or fabric clips to hold layers in place. Additionally, adjusting the machine’s tension and stitch length can help achieve optimal results. A slightly longer stitch length is often recommended for fabrics with more stretch, allowing for flexibility.


  • In the realm of industrial sewing, cylinder bed sewing machines have carved out their niche due to their unique design and versatility. These machines are particularly favored for sewing cylindrical or tubular items such as sleeves, cuffs, and pant legs. However, when considering the adoption of such equipment, potential buyers often find themselves wondering about the price range and what factors can influence these costs.


  • Besides edge finishing, overlockers can also perform various stitches, including flatlock and chain stitches. Flatlock stitching is especially beneficial for activewear, as it lies flat against the skin and reduces irritation, while chain stitching offers flexibility and strength, making it suitable for stretchable fabrics. Many modern overlockers also come with adjustable settings, allowing users to customize the stitch width, length, and tension to suit different fabric types and project needs.


  • 1. Tension Settings Adjusting your sewing machine's tension settings may be necessary when using heavy-duty thread. A loose tension can cause loops and poor seam quality, while too much tension can break the thread. Perform a test stitch on a scrap piece of canvas to find the right balance.


  • 3. Enhanced Stitch Quality The dual needles create a distinct and appealing stitch line, enhancing the aesthetic quality of your finished garments. Additionally, the walking foot reduces the risk of thread breakage, particularly when working with challenging fabrics like knits or dense materials.


  • - Canvas and Outdoor Gear For items exposed to the elements, such as tents, tarps, or outdoor gear, using heavy duty needles ensures that stitches remain intact and secure.


  • Thread Choice Considerations

  • Correct Angle and Positioning


  • Applications of Lockstitch Seam


  • Another important aspect of maintenance is keeping your machine properly adjusted and calibrated. Check the tension of the thread regularly and make any necessary adjustments to ensure that your stitches are even and balanced. Additionally, keep an eye on the condition of your needles and replace them as needed to prevent skipped stitches or damage to your fabrics.

  • When using heavy duty thread for sewing leather, it is important to choose the right type and weight of thread for the job. There are several different types of heavy duty thread available, including nylon, polyester, or even waxed thread. The weight of the thread can also vary, with heavier weights being better suited for thicker leather and lighter weights being better for thinner leather.
