Prof. Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), wrote of the decision: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive. A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body.”
Resumen–En este artículo se discute el descubrimiento del litopón fosforescente en dibujos a la acuarela por el artista americano John La Farge, fechados de 1890 a 1905, y la historia del litopón en la industria de los pigmentos a finales del Siglo XIX y principios del Siglo XX. A pesar de tener muchas cualidades deseables para su uso en pintura para acuarela o pinturas al óleo blancas, el desarrollo del litopón como pigmento para artistas fue obstaculizado por su tendencia a oscurecerse con la luz solar. Su disponibilidad para los artistas y su adopción por ellos sigue siendo poco clara, ya que por lo general los catálogos comerciales de los coloristas no eran explícitos al describir si los pigmentos blancos contenían litopón. Además, el litopón se puede confundir con blanco de plomo durante el examen visual, y su fosforescencia de corta duración puede ser fácilmente pasada por alto por el observador desinformado. A la fecha, el litopón fosforescente ha sido documentado solamente en otra obra mas: una acuarela por Van Gogh. Además de la historia de la fabricación del litopón, el artículo detalla el mecanismo para su fosforescencia, y su identificación con la ayuda de espectroscopía de Raman, y de espectrofluorimetría.
When it comes to vehicle maintenance, ensuring the braking system is in optimal condition is paramount for safety. Among various brake systems, drum brakes are still prevalent in many vehicles, particularly in older models and some budget-friendly options. For anyone looking to perform their own brake maintenance or repairs, having a dedicated drum brake tools kit is essential.

In addition to functional benefits, brake drum covers offer aesthetic advantages as well. Available in a variety of designs and finishes, these covers can give a vehicle a polished and customized look. Whether a vehicle owner prefers a classic, understated appearance or a more aggressive, sporty style, there are brake drum covers that can complement their specific taste. For car enthusiasts, these covers can be a simple yet effective way to enhance the overall look of their vehicle, contributing to its uniqueness.
The cost of replacing rear drum brake shoes can vary significantly based on several factors
First and foremost, it’s important to understand the symptoms of seized drum brakes. You may experience a grinding noise, a burning smell, or your vehicle may pull to one side when braking. In some cases, the drums may not release the brakes even when you’re not pressing the pedal. If you suspect your drum brakes are seized, the first step is to safely lift the vehicle and secure it on jack stands.
En resumen, el mecanizado de tambores de freno es un proceso esencial que no solo mejora la seguridad de los vehículos, sino que también prolonga la vida útil de los componentes del sistema de frenos. Con la tecnología actual y técnicas avanzadas, este proceso se vuelve cada vez más preciso y eficiente, lo que contribuye a una conducción más segura y confiable.

Når du opplever støy fra bakbremstromlene, er det viktig å ta dette på alvor. Støyen kan være et tidlig varselsignal om et underliggende problem som kan forverres over tid. Det anbefales å oppsøke en kvalifisert mekaniker for en grundig sjekk av bremsesystemet. De kan identifisere kilden til støyen og anbefale nødvendige reparasjoner eller bytter for å sikre at bremsene fungerer optimalt.
One of the primary benefits of rear drum brakes is their cost-effectiveness. They are generally less expensive to manufacture and replace than disc brakes, making them a popular choice for budget-friendly vehicles, particularly for older models. Additionally, drum brakes provide a larger surface area for braking, which can result in effective braking performance. They also tend to have better holding power, making them advantageous for vehicles that require reliable parking brake functionality.
Finally, measure the brake shoes. Check both the thickness and the length. The thickness should be measured at the shoe's center, ensuring it has enough padding left for effective braking. If the shoes are nearing their minimum thickness, they should be replaced to maintain optimal braking performance.

یکی دیگر از نشانههای واضح نیاز به تعویض ترمزهای درام، روشن شدن چراغ هشدار ترمز در داشبورد است. اگر این چراغ روشن شد، به احتمال زیاد مشکلی در سیستم ترمز وجود دارد که نیازمند بررسی و تعمیر فوری است.
When the brake pedal is pressed, hydraulic fluid is sent to the wheel cylinders, pushing the brake shoes outward against the drum. This action generates friction, which slows the rotation of the wheels, thereby bringing the vehicle to a stop.
Daarnaast is het belangrijk om te benadrukken dat de keuze van materialen ook invloed heeft op de uiteindelijke kwaliteit van de remtrommels. Hoogwaardige legeringen die speciaal ontwikkeld zijn voor gebruik in remsystemen worden vaak ingezet. In combinatie met de precisie van de forge stand zorgt dit voor remtrommels die niet alleen langer meegaan, maar ook beter presteren in kritieke situaties.

Always remember to consult professional resources or seek expert help if you encounter difficulties during the conversion process. Happy driving!
1. Worn Components As brake shoes and drums wear down over time, they may no longer fit securely, leading to lift.
Drum brakes are the traditional braking system, comprising a drum that rotates with the wheel and brake shoes that press against the inner surface of the drum to create friction. This system has been widely used due to its cost-effectiveness and simplicity. However, drum brakes do have some limitations, particularly in terms of heat dissipation and performance under heavy loads.
Một trong những yếu tố quan trọng nhất làm tăng chi phí là loại phanh đĩa được sử dụng. Trên thị trường hiện nay, có nhiều loại phanh đĩa với các mức giá khác nhau.

Unlike disc brakes, which have a rotor and a caliper, drum brakes consist of a cylindrical drum and brake shoes. This design is particularly effective for heavy-duty applications, as it provides a larger surface area for friction, which is crucial for slowing down large vehicles. In most semi trucks, the rear wheels utilize brake drums, while the front typically feature disc brakes, combining the strengths of both systems.

Maraming dahilan kung bakit nagiging sanhi ng paghahatak ang mga drums ng preno. Ang isa sa mga pangunahing dahilan ay ang hindi wastong pagsasaayos ng preno. Kung ang mga pad ng preno ay hindi maayos na nakaposisyon, maaari silang manatiling naka-contact sa drum kahit na ang preno ay hindi ginagalaw. Bukod dito, ang kontaminasyon mula sa langis o tubig sa mga pad ng preno ay maaari ring magdulot ng pagkakadulas, na nagreresulta sa paghahatak.
Understanding Aircraft Drum Brakes A Comprehensive Overview
One of the most significant advantages of disk brakes is their superior heat dissipation. When brakes are applied, friction generates heat, which can lead to brake fade—a reduction in braking effectiveness due to overheating. Disk brakes, with their open design and larger surface area, are better at dissipating heat. As a result, they maintain consistent performance even under heavy braking conditions. In contrast, drum brakes trap heat within the drum, making them more susceptible to overheating and fade.
