NEW DELHI: Caustic soda prices drifted by Rs 50 per 50 kg in the national capital today owing to reduced offtake by consuming industries against fresh arrivals from producing regions. Caustic soda flake fell by Rs 50 to Rs 1,800-1,900 per 50 kg. Traders said subdued demand from consuming industries against increased arrivals from producing belts mainly pulled down caustic soda prices. The following are today’s quotations: Ammonium chloride (50 kg) Rs 1,100-2,400, Acetic acid (1 kg) Rs 40-50, Ammonia bicarb (25 kg) Rs 500-900, Boric acid technical (50 kg) Rs 4,500-5,200, Borex granular (50 kg) Rs 2,200-2,600. Caustic soda flake (50 kg) Rs 1,800-1,900, Citric acid (50 kg) (China) Rs 3,500-4,000, Citric acid deshi (50 kg) Rs 3,000-3,300, Camphor slab (1 kg) Rs 415, Camphor powder (1kg) Rs 335, Glycerine (1 kg) Rs 100-120, Hexamine (1kg) Rs 95, Hydrogen peroxide (1 kg) Rs 35-50, menthol bold crystal (per kg) Rs 1,075, menthol flake (1 kg) Rs 1,025 and mentha oil (1kg) Rs 895.

Q what is gabardine polyester

Synthetic oil and standard (conventional) oil are both used for engine lubrication, but they differ significantly in their formulation and performance. Synthetic oil is chemically engineered from petrochemicals with a controlled molecular structure that provides superior properties. It offers better temperature stability, reduced engine wear, and longer oil change intervals compared to conventional oil, which is refined from crude oil with more irregular molecular sizes. Synthetic oil also functions more effectively at both high and low temperature extremes. However, it is more expensive than standard oil, which might be a consideration for users. Given these advantages, synthetic oil is often recommended for newer, high-performance vehicles or in harsh driving conditions, while conventional oil might still be suitable for older cars or less demanding use cases.

Q how to clean fibers off surface of an iron

To clean glass without leaving fibers or streaks behind, begin by selecting a high-quality microfiber cloth or a squeegee–these tools are designed to limit fiber residue. Avoid paper towels or cotton cloths, as they tend to shed. Prepare a cleaning solution of equal parts distilled water and white vinegar; the vinegar will help dissolve grime without leaving residues. Apply the solution with a spray bottle, then gently wipe the glass in a Z-shaped pattern with the microfiber cloth or drag the squeegee from top to bottom for larger surfaces. If using a cloth, rotate to a clean section as it becomes saturated to avoid redepositing dirt. For optimal results, clean on an overcast day or when the glass is cool to touch to slow the evaporation rate, thus reducing streaks. Finally, buff any remaining streaks with a dry part of the cloth.

Q calorific value of polypropylene in btu

The calorific value of a material is a measure of the energy released during its combustion. Polypropylene, a commonly used plastic in various industries due to its properties, has a significant calorific value. Specifically, the calorific value of polypropylene is approximately 19,900 to 20,000 BTU/lb (British Thermal Units per pound). This high calorific value indicates that polypropylene can release a substantial amount of energy when burned, which is why it finds utility in waste-to-energy plants as a potential fuel source. However, it’s important to consider the environmental impact of burning plastics such as polypropylene, as it can lead to the release of harmful pollutants. Alternative disposal methods and recycling are recommended to minimize this impact.

Q structural difference between high density and low density polyethylene

The primary structural difference between high density polyethylene (HDPE) and low density polyethylene (LDPE) lies in the degree of branching. HDPE has a linear structure with minimal branching, which results in a tightly packed arrangement of polymer chains. This structure grants HDPE its high strength and density. In contrast, LDPE features a high degree of branching, with side chains extending from the main polymer chain. Such branching leads to a more loosely packed structure, rendering LDPE more flexible but with lower strength and density. This branching variation is a result of differing polymerization processes: HDPE is typically synthesized using low pressure and catalysts that promote linear growth, whereas LDPE is produced under high pressure, which encourages branching. As a result, HDPE is suited for products requiring rigidity and strength, like milk jugs and water pipes, while LDPE is preferable for applications needing flexibility, such as plastic bags and wrap.

Q what is woven polypropylene

JessicaClark

KerwinWindsor Release Time: May 4, 2024, 10:19 AM

Woven polypropylene (PP) is a durable, versatile plastic fabric made by interlacing polypropylene tapes in a weaving loom. This process creates a lightweight, yet incredibly strong material that resists tearing, stretching, and water damage. Its strength and resistance to chemicals, mildew, and moisture make it popular for bulk bags, tarps, and sacks used in agriculture, construction, and packaging industries. Woven PP can also be recycled, making it an eco-friendlier option for many applications. Its ability to be printed on makes it useful for branded packaging solutions, offering both practicality and promotional benefit.

Q reaction of zinc with caustic soda

PenelopeIrving

KerwinWindsor Release Time: April 25, 2024, 5:27 AM

Zinc reacts with caustic soda (sodium hydroxide, NaOH) to produce sodium zincate (Na2ZnO2) and hydrogen gas (H2). The reaction equation is Zn + 2NaOH + 2H2O → Na2ZnO2 + 2H2↑. This reaction is characteristic of an amphoteric metal, meaning zinc can react with both acids and bases. The production of hydrogen gas is a typical indicator of such reactions. This process is often utilized in laboratories to demonstrate the amphoteric nature of zinc and the production of hydrogen gas. Safety precautions are necessary to handle caustic soda and the hydrogen gas produced.

Polyester fiber is a synthetic material known for its durability, resistance to shrinking and stretching, and quick-drying properties. Microscopically, it appears as long, smooth, and straight filaments which can be woven together tightly or loosely, depending on the desired fabric texture. These fibers can vary in thickness and length, giving manufacturers flexibility in the types of fabric they produce, from sheer and lightweight to thick and heavy. To the naked eye, polyester fibers in fabrics can look glossy or matte, mimicking the appearance of natural fibers like cotton or silk, making it a versatile choice in the textile industry. Its ability to be dyed in a wide range of colors further adds to its appeal for various fashion and home furnishing applications.

Polyester and nylon are two different types of synthetic polymers widely used in the textile industry. Polyester is known for its durability, resistance to stretching, shrinking, and wrinkles. It is derived from petroleum and is used in a variety of applications, from clothing to home furnishings. Nylon, on the other hand, was the first fabric made entirely in a laboratory and offers exceptional strength, elasticity, and resistance to mildew. It is also quick-drying, making it popular for sportswear and outdoor gear. Both materials are often blended together to combine the best qualities of each, resulting in a fabric that is durable, stretchable, and easy to care for, making it an excellent choice for a wide range of applications.

KerwinWindsor Release Time: April 24, 2024, 10:02 AM

HP 63 ink cartridges come in two types: black and tri-color. The black ink in HP 63 cartridges is pigment-based, providing sharp and durable text prints, ideally suited for document printing. On the other hand, the tri-color cartridge uses dye-based ink, which delivers vivid and bright colors, making it perfect for printing photos and images. This combination of pigment and dye-based inks allows users to achieve a balance between durable text documents and vibrant colored prints. Thus, for users looking to make the most out of their printing, it’s beneficial to understand the specific properties and applications of the ink types in HP 63 cartridges.
