Product Description: Factory-Use 220V 50W Maintenance-Free Explosion-Proof LightPreviously, in petrochemical enterprises, explosion-proof lighting fixtures were primarily used in hazardous areas. With the application of increased safety electrical equipment in Zone 2 hazardous locations, increased safety and composite lighting fixtures are increasingly being utilized. Increased safety fixtures, while offering certain explosion-proof performance, are lighter in weight, lower in cost, easier to install and maintain, and have a longer service life compared to explosion-proof fixtures. The commonly used composite electrical equipment in petrochemical enterprises is the increased safety-explosion proof composite explosion-proof electrical equipment, generally consisting of three parts: explosion-proof components, increased safety terminals, and an increased safety enclosure. It combines the safety performance of explosion-proof types with the advantages of increased safety types. In daily maintenance, the following points should be noted.The explosion-proof light should automatically cut off power before the lampshade is opened. However, due to the complexity of setting up interlock devices, this is not easily achievable, so most fixtures only have a warning sign with words like "Do not open when powered" in a conspicuous place on the enclosure. Additionally, since the surface temperature of the bulb remains high after power-off, immediately opening the lampshade could still risk igniting explosive gas mixtures (mainly referring to explosion-proof structures). Therefore, for light sources with high surface temperatures like incandescent, high-pressure mercury, and high-pressure sodium lamps, and fixtures that can be opened quickly, this point must be noted. The CeY-1 explosion-proof fluorescent lamp, widely used in the author's unit, features an interlock mechanism that cuts power when the cover is opened, providing convenience and safety for maintenance work. As fluorescent lamps are cold light sources, they do not have high surface temperatures, allowing the cover to be opened immediately after power-off.Factory-Use 220V 50W Maintenance-Free Explosion-Proof Light Waterproof and Dustproof Factory Lighting Super Bright: Applicable Scope:◆ Suitable for explosive gas mixture temperature groups T1 to T6.◆ Suitable for hazardous areas with explosive gas mixtures: Zone 1, Zone 2.◆ Suitable for combustible dust areas: Zone 21, Zone 22.◆ Suitable for hazardous areas with explosive gas mixtures of Class IIA, IIB, IIC.◆ Suitable for fixed lighting in workshops or plants such as chemical plants, warehouses, boiler rooms, storage areas, tank farms, steel plants, etc.Structural Performance:◆ This product is designed and manufactured in full compliance with explosion-proof requirements, offering excellent explosion-proof effects and safe, reliable operation in various environments.◆ The enclosure is made of high-quality aluminum alloy die-cast, offering high strength and surfaceTechnical Parameters:Parameter Name ValueLight Source Type LED Light SourceLight Source Process SMD Surface-MountEnclosure Protection Rating IP65Enclosure Corrosion Resistance Rating WF2Power Factor ≥0.95Power Supply Efficiency ≥0.88Inlet Specification G3/4" (Φ6～Φ12mm)Light Source Color Temperature 5500K～6500KDimensions Φ205×115mmFixture Weight 2.8KgRecommended Installation Height 2m～5mRecommended Installation Distance 2m～3mExplosion-Proof Mark Exde IIC T6 Gb/Ex tD A2IP65 T80℃Power: 5W 10W 20W 30W 40W 50W 60W 70W 80W 90W 100W 110W 120W130W 140W 150W 160W 180W 200W 220W 240W 260W 300WInstallation Methods Ceiling-mounted (x), Pole-mounted (g), Wall-mounted (b30°/b90°), Guardrail-mounted (h), Flange-mounted (f) more>

Product Description: Indoor non-intumescent steel structure fireproof coating; Indoor non-intumescent fireproof coating; Xinguida Sales Representative: (Manager Zheng: 199-2310-0068). Xinguida Company provides honest services throughout the entire process of paint selection, matching, and construction; throughout every stage of quality control, inspection, and after-sales service; allowing customers to deeply experience the consistent high-end and premium quality demonstrated by Xinguida coatings! In our operations, we continuously deepen internal management, pursue reform and progress, advance our global market presence, and follow an industrial direction to make coating materials and chemicals benefit humanity and promote social progress.In construction projects, fireproof coatings are often required. Depending on their performance, there are two types: intumescent and non-intumescent. Let’s take a look at non-intumescent fireproof coatings.Non-intumescent fireproof coatings are generally made from inorganic materials, primarily thermal insulation materials. During application, the coating is relatively thick, and it does not expand or foam when exposed to fire. Instead, it relies on the inherent properties of the thermal insulation material to block heat. Due to the thick coating, direct flame exposure may cause some material components to decompose and evaporate, with the resulting reactions absorbing heat, thus providing a longer fire resistance duration.I. Types of Non-Intumescent Fireproof CoatingsThese include indoor non-intumescent fireproof coatings (thin and ultra-thin types), outdoor non-intumescent fireproof coatings (thin and ultra-thin types), market-type protective coatings, and cable fireproof coatings, among others. Non-intumescent fireproof coatings function by providing fire insulation and heat resistance during a fire incident. Since they do not expand and have low thermal conductivity, they effectively extend fire resistance time, thereby offering fire protection.II. How Non-Intumescent Fireproof Coatings Provide Fire Protection:1. The coating itself is flame-retardant or non-combustible.2. Under flame or high-temperature conditions, the coating releases fire-extinguishing gases and forms an inorganic "glaze" layer that isolates air.With socio-economic development, ultra-high-rise steel structures, large-span steel factories, civil buildings, and general industrial steel structures increasingly use thick fireproof coatings. By innovating and developing traditional application methods for thick steel structure fireproof coatings, and clarifying requirements for interlayer intervals and mix ratios, we better address issues such as hollowing, cracking, and detachment that occur in general spray application projects. This improves project quality, shortens construction time, and ensures that the fire resistance performance of thick fireproof coatings in steel structures meets design and regulatory standards.III. Recommended Measures for Natural Environmental Conditions:(1) For areas near doors, windows, and peripheral sections, use colored tarps for protection. In conditions with strong wind and air humidity below 40%, control the application time for each coat to no more than 2 hours, then proceed immediately to the next layer following the first layer’s spraying sequence. Ensure all three coats are applied continuously in this cycle until completed. When air humidity is above 70%, appropriately extend the interval between coats, allowing the surface to reach 30-40% dryness (approximately 4 hours apart).(2) After application, maintain the steel structure by wrapping it in plastic film for 12 hours. The curing period is generally 3-4 days.(3) For detailed treatment of corners, special-shaped components, and joints that are not timely or dense, take the following measures: * Seal gaps in steel structure joints, carefully spray detailed areas, and apply alkali-resistant fiberglass mesh.(This article is from the internet, intended for display purposes only.
