Storage of Tungsten Wire for Glass Heating 5

The storage of tungsten wire for glass heating requires special attention to its physical and chemical properties to ensure that its performance is not damaged and its service life is extended. 1. Storage in a Dry Environment Tungsten wire is sensitive to moisture and humidity. Long-term exposure to a humid environment may cause oxidation, affecting its conductivity and high temperature resistance. Therefore, a dry, well-ventilated environment should be selected for storage to avoid high temperature and high humidity. It is…

Transportation of Tungsten Wire for Glass Heating 14

The transportation of tungsten wire for glass heating needs to pay special attention to its physical properties and safety requirements. The following are relevant suggestions: 1. Packaging Requirements: Shock protection: Tungsten wire is brittle and easily broken by vibration or impact. It should be wrapped with foam, bubble film or special shockproof materials to avoid collision. Sealed packaging: Tungsten wire is easy to oxidize and needs to be sealed in a vacuum or inert gas (such as nitrogen, argon) environment,…

Packaging of Tungsten Wire for Glass Heating 18

The packaging of tungsten wire for glass heating usually needs to consider factors such as high temperature tolerance, oxidation resistance, moisture resistance, and transportation safety. The following are some common packaging methods and precautions: 1. Vacuum Packaging: Tungsten wire is easy to oxidize at high temperatures, so vacuum sealed packaging (such as vacuum plastic bags or vacuum aluminum foil bags) is often used to isolate the air and prevent oxidation and moisture intrusion. This packaging can effectively extend the shelf…

Production Steps of Tungsten Wire for Glass Heating 8

Tungsten wire is an ideal choice for glass heating applications due to its high melting point and high temperature resistance. The following is a brief overview of the main production steps for producing tungsten wire for glass heating: 1. Tungsten Ore Extraction and Refining: Tungsten trioxide (WO?) is extracted from tungsten ore (such as wolframite or scheelite). Impurities such as sulfur and arsenic are removed through chemical treatment (such as acid leaching and solvent extraction) to obtain high-purity tungsten trioxide.…

What Is Tungsten Nail Sinker? 5

Tungsten nail sinker is a fishing tool crafted from metal tungsten as the primary material, processed into a slender needle-like shape, and categorized as a subset of “sinkers” in fishing accessories. Its core feature leverages tungsten’s high density (approximately 19.3 g/cm3), achieving significant weight in a small volume while optimizing hydrodynamic performance post-entry into water. Compared to iron sinker: 1) Tungsten nail sinker has a higher specific gravity, resulting in a smaller volume at the same weight, reducing wind resistance…

Differences Between Tungsten Sinker and Lead Sinker 5

Tungsten sinker and lead sinker are both common fishing weight tools, available in shapes like teardrop, cylindrical, and olive forms. However, they differ across multiple dimensions, including production costs, materials, performance, and manufacturing processes. I. Material Aspects Tungsten sinker is an alloy primarily composed of tungsten (85%–99%) with small amounts of nickel, iron, and other metals, designed for fishing. Lead sinker, also known as a lead weight, is made mainly of lead or lead-tin alloys and is an essential auxiliary…
