The quality of agricultural vehicle running-in has a significant impact on the power, economy, reliability and service life of agricultural vehicles. Therefore, the following requirements must be met.

Reduce the load. During the running-in period, the load of the agricultural vehicle shall not exceed 80% of its rated load, and no trailer or other implements shall be towed. It is best to drive first within a few tens of kilometers of use, and then gradually increase the load. The gears used for driving under various load capacities must be upgraded from low to high step by step, and each gear should be run-in, and the common gears should be more wear-in.

Choose high quality fuel and lubricants. During the running-in of agricultural vehicles, diesel with higher cetane number and lubricating oil with low viscosity and good quality should be used to improve the lubrication conditions of various parts and prevent the engine from working rough.

Control the speed of the car. The maximum speed of general agricultural vehicles should not exceed 40km/h, and the speed limit device must not be removed.

Control engine operating temperature. When the agricultural vehicle is running in winter, the engine should be preheated to above 40 °C before starting. During driving, the temperature of the cooling water should always be maintained within the range of 75 to 95 °C.

Choose a good road. Agricultural vehicles should not be driven on poor quality roads during the running-in period. Do not climb steep slopes to reduce the vibration and impact of the parts and prevent excessive load.

Do not slam the throttle when starting the engine and parking. Start and accelerate slowly, shift gears in time, try not to use emergency braking.

Strict implementation of the maintenance period of the running-in period. In order to ensure the running-in quality, before the start-in, the whole car should be cleaned, the lubricating oil, grease and special liquid of each part should be inspected and supplemented, and the fasteners of each part should be checked. After driving for 500km, clean the engine lubrication system and the chassis gearbox, and replace the lubricating oil; lubricate the lubrication points of the entire vehicle, check the braking performance and the technical status of the various piping and fasteners, and tighten if necessary. Solid adjustment; tighten the bolts and nuts of the cylinder head and the intake and exhaust pipes, check and adjust the valve clearance.

Anti-oxidant Raw Material

What antioxidant ingredients are included in cosmetics?

Antioxidants are a class of chemical substances that can delay or prevent oxidation reactions and can effectively protect ingredients in cosmetics from oxidative damage. Oxidation is a chemical reaction caused by free radicals, which can lead to quality changes, color changes, odor changes and even spoilage of ingredients in cosmetics. The role of antioxidants is to maintain the stability and quality of cosmetics by trapping free radicals and inhibiting the occurrence of oxidative reactions.

Common antioxidants include vitamin C, vitamin E, polyphenolic compounds, and flavonoids. Vitamin C (ascorbic acid) is a water-soluble antioxidant that reacts with free radicals to inhibit oxidative reactions. Vitamin E (tocopherol) is a fat-soluble antioxidant that traps free radicals in the lipid environment and protects lipids from oxidation. Polyphenolic compounds and flavonoids are a class of natural antioxidants that can be derived from plants and have strong antioxidant capacity.
In cosmetics, antioxidants are often added to products such as skincare, sunscreen, and anti-aging products to slow down the oxidation process and maintain their stability and effectiveness. Antioxidants can also provide additional skin care benefits such as anti-inflammatory, anti-aging, and blemish reduction. However, antioxidants need to be used with caution and overuse may lead to irritation or allergic reactions. Therefore, when using antioxidants in cosmetics, the amount of antioxidants used needs to be rationally selected and controlled according to the formulation of the product and the purpose of use.
