The duty was first imposed on August 18, 2015 for five years. New Delhi: India extended anti-dumping duty on imports of caustic soda from China and Korea till November 2020. The duty was extended after considering the recommendations of the commerce ministry’s investigation arm Directorate General of Trade Remedies (DGTR), that had requested for extension of the existing anti-dumping duty on the chemical imported from China and Korea.”The anti-dumping duty imposed under this notification, with respect to People‟s Republic of China and Korea RP, shall remain in force up to and inclusive of the 17th November, 2020, unless revoked, superseded or amended earlier,” the Central Board of Indirect Taxes and Customs (CBIC) said in a notification on Monday. The duty was first imposed in 2012 on a different set of countries to protect local industry from cheap foriegn imports. The duty was then imposed on material coming from China and Korea in 2015 for a period of five years.

Blow molding is a manufacturing process used to create hollow plastic parts by inflating a heated plastic tube (parison) inside a mold. The process begins when a plastic parison, heated to a pliable state, is placed in a mold. Air is then blown into the parison, inflating it to fit the mold’s shape. Once the plastic cools and solidifies, the mold opens to release the formed part. This method is widely used for producing bottles, containers, and other hollow shapes. Blow molding offers advantages in terms of speed and cost, especially for high-volume production. However, the initial cost for molds and machinery can be high, making it less suitable for small-run items. The technique emphasizes efficiency and versatility, enabling manufacturers to produce a wide range of products with varying sizes, shapes, and specifications.

During mitosis and meiosis, kinetochore fibers, which are part of the spindle apparatus, play a crucial role in chromosome movement. They are thought to attach to the kinetochore, a protein structure on the chromosome’s centromere, ensuring accurate chromosome segregation. In mitosis, this process facilitates the even distribution of chromosomes into two daughter cells, maintaining genetic consistency. In meiosis, kinetochore fibers contribute to the separation of homologous chromosomes (meiosis I) and sister chromatids (meiosis II), essential for producing genetically unique gametes. The precise attachment and movement facilitated by kinetochore fibers are fundamental for genetic diversity and stability across generations.

Q what is functional fiber

While fiber does not completely eliminate carbohydrates, it does play a role in the way our bodies handle them. As a type of carbohydrate that cannot be digested, fiber does not break down into sugar like other carbs do. There are two types of fiber: soluble and insoluble. The former slows down the absorption of sugar and can impact blood sugar levels. Therefore, it can regulate the amount of carbs entering our system. For those monitoring their carb intake, fiber is helpful in calculating net carbs (total carbs minus fiber). However, it’s important to note that while useful in this aspect, fiber should not be considered a complete replacement for carbs. Its main function is influencing how our bodies process them.

Q does polypropylene breakdown

JayChristiana

RoderickAdam Release Time: May 14, 2024, 12:44 PM

Polypropylene (PP) is a durable plastic widely used in various applications, from packaging to automotive parts. However, like all plastics, it is not immune to breakdown over time. Under normal environmental conditions, polypropylene can take several hundreds of years to decompose, a significant environmental concern given its widespread use and disposable nature. The degradation process can be accelerated by exposure to UV radiation from sunlight, mechanical stress, or chemical attack. Recent research focuses on enhancing the biodegradability of PP through various means, such as incorporating biodegradable additives or through specific recycling processes. Nonetheless, the slow degradation rate of polypropylene in natural environments underscores the importance of responsible use, waste management, and recycling to mitigate its environmental impact.

RoderickAdam Release Time: May 8, 2024, 12:00 PM

High Density Polyethylene (HDPE) welding is a process used to join HDPE materials, common in various industries such as plumbing, automotive, and construction. This plastic welding technique usually involves methods like hot gas welding, extrusion welding, or butt fusion welding. Hot gas welding uses a heat gun that emits a jet of hot air to melt the surfaces to be joined, along with a filler rod. Extrusion welding employs a handheld extruder that emits molten plastic to fuse pieces together. Butt fusion involves heating the ends of the pieces and pressing them together. Proper cleaning and preparation of the surfaces, along with the correct temperature and pressure, are crucial for a strong and durable weld. HDPE welding is beloved for its simplicity and strength, but it requires expertise to ensure the welds are leak-proof and long-lasting.

Plastic properties refer to the behaviors and characteristics that define how plastic materials respond under various conditions. Key properties include malleability, allowing plastics to be molded into different shapes; durability, which makes them resistant to impact and wear; lightweight nature, facilitating ease in handling and transport; and chemical resistance, enabling their use in various environments without degrading. However, these same properties can contribute to environmental challenges, such as pollution and difficulty in degradation. Innovations in biodegradable plastics and recycling methods are being developed to address these issues. Understanding plastic properties is crucial for both maximizing their advantageous uses in society and mitigating their environmental impact.

Q heat capacity of hdpe

TammySidney

RoderickAdam Release Time: May 7, 2024, 3:23 AM

HDPE. or High Density Polyethylene. typically has a heat capacity ranging from 1.67 to 2.30 J/g C. In simpler terms. this is the amount of energy needed to increase its temperature by one degree Celsius. The specific formulation and processing conditions may cause slight variations in heat capacity for HDPE. With a relatively high heat capacity compared to other plastics. HDPE is highly sought after for its exceptional insulation and resistance to temperature changes. This makes it a popular choice for uses like hot and cold fluid piping and outdoor furniture. It’s crucial for engineers and designers to understand the heat capacity of HDPE in order to anticipate how it will behave under various environmental conditions and applications.

Q what dissolves polyester

ElroyShaw

RoderickAdam Release Time: April 25, 2024, 3:02 AM

Polyester, a synthetic polymer made from petroleum derivatives, is known for its durability and resistance to many chemicals. However, certain solvents can dissolve it. The most effective are aromatic hydrocarbons, such as benzene, toluene, and xylene. These solvents break down the polyester chains, leading to dissolution. Acetone can also affect polyester, especially in its uncured form, but is less effective on cured polyester fabrics. It’s important to use these chemicals with caution due to their potentially harmful effects on health and the environment. In practical applications, knowing which substances dissolve polyester is crucial for recycling processes or when needing to remove polyester-based adhesives or coatings.

RoderickAdam Release Time: April 24, 2024, 3:13 AM

Polyester capacitors, known for their high dielectric constant and stability, are widely used across various applications, including consumer electronics, power supplies, and automotive electronics. They offer an excellent balance between cost and performance, making them a preferred choice for applications where the high precision of film capacitors is needed, yet without the need for the extreme tolerance levels or environmental stability of ceramic or electrolytic capacitors. Polyester capacitors are beneficial in filtering applications where reliability and economy are crucial. They are ideal for coupling and decoupling applications due to their non-polarity and ability to operate over a wide range of temperatures and frequencies. Additionally, their compact size allows for easy integration into densely packed circuits, providing a reliable solution for smoothing out voltages, bypassing low-frequency noise, and in timing circuits where their known frequency characteristics can be u...
