The National Cancer Institute tested TiO2 for possible carcinogenicity by the oral route of exposure by feeding rats and mice with TiO2 (size not specified) at doses 25,000 or 50,000 ppm TiO2 for 103 weeks. They concluded that TiO2 was not carcinogenic.Also, the study with rats fed diets containing up to 5 % TiO2 coated mica for 130 weeks showed no treatment-related carcinogenicity. Since the size and other TiO2 properties were not specified or determined, we cannot generalize this conclusion and we have to take into account other possible outcomes of this scenario in different exposure conditions (other size/crystalline structure of TiO2 etc.).
This article reviews the uses, benefits, and safety of titanium dioxide.
A 2023 study published in the journal Particle and Fibre Toxicology set out to examine the impact of titanium dioxide nanoparticles in mice “on the course and prognosis of ulcerative colitis,” by creating an ulcerative colitis disease model. Researchers found that the titanium dioxide nanoparticles significantly increased the severity of colitis. They also “decreased the body weight, increased the disease activity index and colonic mucosa damage index scores, shortened the colonic length, increased the inflammatory infiltration in the colon.” Researchers concluded: “Oral intake of TiO2 nanoparticles could affect the course of acute colitis in exacerbating the development of ulcerative colitis, prolonging the ulcerative colitis course and inhibiting ulcerative colitis recovery.”

Bromsskivor är utsatta för konstant friktion och värme varje gång bilen bromsar. När bromspedalen trycks ned pressas bromsbeläggen mot skivorna, vilket skapar det nödvändiga greppet för att sakta ner fordonet. Denna process leder till en gradvis nedbrytning av både bromsbelägg och bromsskivor. Bromsskivorna kan slitas ut av flera anledningar, inklusive överhettning, kontaminering av olja eller smuts, och ojämn förslitning.
The brake drum is a cylindrical component that houses the braking mechanism. It is typically made of cast iron or aluminum, designed to withstand the high temperatures generated during braking. Brake shoes, on the other hand, are curved pieces of friction material that press against the inner surface of the brake drum to create the necessary friction to slow down or stop the vehicle.
Yeni fren diskinizi alın ve dikkatlice yerine oturtun. Diskin doğru yerleştiğinden emin olduktan sonra vidaları tekrar sıkın. Vidaları sıkarken, çapraz şekilde sıkmaya özen gösterin, böylece disk düzgün bir şekilde yerleşir.

The braking system of any vehicle is crucial for maintaining safety and control. One key component of this system is the brake drum, which plays a vital role in the braking mechanism, especially in vehicles equipped with drum brakes. Understanding the concept of maximum allowable brake drum diameter is essential for mechanics, vehicle manufacturers, and drivers alike, as it has significant implications for vehicle safety and performance.

Калі барабан зняты, вы можаце прыступіць да замены тормазных калодак. Знайдзіце замковае весло і акуратна зніміце старыя калодкі. Устаньце новыя калодкі, пераканаўшыся, што яны ўстаноўлены правільна і зафіксаваны на сваіх месцах. Затым пастаўце новы барабан на месца, упэўніўшыся, што ён добра прылягае.
3. Apply Penetrating Oil Spray a generous amount of penetrating oil around the drum where it meets the spindle. Allow it to soak for a few minutes to loosen any rust.

Il est important de prendre en compte le coût de l'entretien préventif. D'autres éléments du système de freinage, comme le liquide de frein, doivent également être vérifiés régulièrement pour garantir un fonctionnement optimal. Ignorer ces contrôles peut entraîner des coûts plus élevés à long terme si des réparations majeures deviennent nécessaires.

5. Locate the Adjusting Mechanism In most drum brake systems, there is an adjuster that can be accessed through a slot in the drum or between the brake shoes. This adjuster is typically a star wheel or a ratchet mechanism.

Tóm lại, việc thay đổi từ phanh trống sang phanh đĩa là một quyết định đúng đắn nếu bạn quan tâm đến độ an toàn và hiệu suất của xe. Mặc dù chi phí có thể cao, nhưng lợi ích mà nó mang lại thường xứng đáng với số tiền bạn bỏ ra.
5. Locate the Adjusting Mechanism In most drum brake systems, there is an adjuster that can be accessed through a slot in the drum or between the brake shoes. This adjuster is typically a star wheel or a ratchet mechanism.
6. Adjust the Brake Shoes Using a screwdriver, rotate the adjusting mechanism. Turning it “up” or “clockwise” usually expands the shoes and increases contact with the drum. Make small adjustments, checking the feel of the shoe engagement frequently. You want the shoes to engage firmly without dragging against the drum.
After completing your maintenance or repairs, reinstalling the brake drum is straightforward. Adjust the shoes slightly if needed for a snug fit, then reattach the wheel and lug nuts. It’s essential to torque the lug nuts to the manufacturer’s specifications for safety.

그러나 이러한 다양한 유형의 드럼 중에서 일반적으로 사용되지 않는 한 가지는 디스크 드럼입니다. 디스크 드럼은 실제로 존재하지 않는 개념입니다. 브레이크 시스템에는 디스크 브레이크와 드럼 브레이크 두 가지 주요 유형이 있습니다. 디스크 브레이크는 회전하는 디스크가 브레이크 패드와 접촉하여 제동력을 생성하는 방식으로, 고속 주행 시 효과적인 제동을 제공합니다. 반면 드럼 브레이크는 내부에 있는 드럼이 브레이크 신호에 의해 외부에서 밀려 들어오는 패드와 접촉하여 제동하는 방식입니다.
Painting brake drums black is a simple yet effective way to enhance not just the aesthetics of a vehicle, but also its performance and longevity. By protecting these critical components from corrosion, improving heat dissipation, and allowing for easier wear monitoring, car owners can ensure their vehicles remain safe and optimized for the road. Whether you are an everyday driver or a dedicated car enthusiast, investing time in maintaining your brake drums can pay off significantly in the long run.

If brake drums are found to be in poor condition, they may need to be resurfaced or replaced entirely. Resurfacing involves machining the drum to restore its smooth surface, while replacement is necessary when the drum has reached its wear limit. Regular maintenance not only enhances safety but can also prolong the life of other braking components, reducing overall operating costs.
