How to Remove Old Paint?

Methods for removing old paint from cars include sandblasting, manual removal, mechanical removal, chemical removal, electric sanding, and flame scraping. Among these, manual removal, mechanical removal, and chemical removal are more commonly used. More details are as follows: 1. Chemical removal involves using paint strippers to eliminate old paint films. Commonly used strippers in the past were T-1 and T-2. T-1 stripper is a milky white paste-like liquid composed of ketones, alcohols, benzene, ester solvents, and an appropriate amount of paraffin. It is mainly used to remove old paint films of oil-based paints, ester gum paints, and phenolic paints. T-2 stripper is a mixture of ketones, alcohols, esters, and benzene solvents, with stronger paint film swelling ability and faster removal speed than T-1. It is primarily used for removing old paint films of oil-based paints, alkyd paints, and nitrocellulose paints. 2. Manual removal is a common method in painting work and the only method for partially removing old paint films. It mainly relies on tools like scrapers, knives, wire brushes, and sandpaper to remove old paint from the surface of car body components. This method is simple but labor-intensive and inefficient. 3. Mechanical removal uses electric or pneumatic tools, such as wire wheels, wire sanders, and dry/wet sandpaper sanders, to replace manual scraping and sanding. This method not only improves efficiency but also reduces labor intensity, making it widely used in the car body repair industry.

What's the reason why the Fengguang 580 won't start?

The reasons why the Fengguang 580 won't start are as follows: 1. Circuit or electronic failure: The phenomenon occurs very suddenly without any warning. Circuit failures include: blown fuse, open circuit in the high-voltage coil, open circuit in the low-voltage circuit, detached central ignition wire, leaking distributor rotor, damaged spark plug. Electronic failure mainly refers to the malfunction of the central computer control board. 2. Fuel system failure: Possible locations of fuel system failures include: malfunctioning fuel pump, blocked fuel line, clogged fuel filter, carbon buildup on spark plugs, damaged fuel injectors, etc. 3. Mechanical failure: Common mechanical failures include: broken timing belt (chain), cylinder leakage with no pressure, etc.

Which is more fuel-efficient, 1.5L or 1.6L?

1.6L is more fuel-efficient. Below is a comparison between 1.5L and 1.6L engines: 1. The difference between 1.5L and 1.6L lies in power output, with 1.6L generally being more fuel-efficient. The 1.5L engine offers stronger power, while handling depends on the vehicle's suspension tuning. Quality depends on the engine and cannot be generalized. Under the same conditions, the 1.5L engine consumes slightly more fuel, while the 1.6L is more fuel-efficient. 2. The numbers 1.5 and 1.6 refer to the engine displacement, which is the difference in engine size. Displacement is the total volume swept by all the engine's cylinders, calculated as the volume swept by the piston from top dead center to bottom dead center multiplied by the number of cylinders. Displacement is a crucial structural parameter that comprehensively measures engine size. Engine performance indicators are closely related to displacement—the larger the displacement, the higher the power output. Unit displacement is commonly used to compare different engine sizes. 3. A 1.6L vehicle has a larger displacement, which typically means higher fuel consumption per 100 kilometers, but it also provides faster acceleration. While a 1.5L vehicle may not accelerate as quickly as a 1.6L, the difference in fuel consumption is minimal, with only a 0.1-liter difference in displacement.

Can a pure water vehicle be licensed?

Pure water vehicles can be licensed. The registration steps are as follows: 1. After entering the licensing point, park the vehicle in the designated area in an orderly manner. 2. Obtain the "Application Form for Motorcycle, Light Motorcycle, and Fuel-Powered Vehicle Permit" (hereinafter referred to as the Application Form), fill it out as required, and then wait in line at the review window along with the licensing documents. 3. After passing the review, proceed to the vehicle inspection window with the Application Form and relevant licensing documents to wait in line for vehicle inspection. 4. Once the vehicle passes inspection, go to the recheck window with the Application Form and relevant licensing documents to wait in line for recheck. After passing the recheck, receive the "Installation Notice for Motorcycle, Light Motorcycle, and Fuel-Powered Vehicle Permit" (hereinafter referred to as the Installation Notice). 5. Take the vehicle to the permit installation area with the Installation Notice and wait for the call to install the permit.

What Causes Car Fuses to Blow Frequently?

Here are the reasons why car fuses blow: 1. When cleaning the engine compartment, due to improper sealing of the fuse box, remember not to rinse the fuse box directly with water, as this can easily cause a short circuit in the fuse, leading to failure of the vehicle's electrical components. Most fuse boxes have a clear icon prohibiting water rinsing. 2. When replacing headlights, excessive power can easily blow the fuse. It is advisable to promptly replace the fuse with a higher current rating and upgrade the power cables to prevent excessive current and overheating. 3. High-power audio systems can also cause fuses to blow. When installing high-power electrical devices, always pay attention to the current level and replace the corresponding fuse in time.

What Are the Reasons for Motorcycle Stalling During Cold Weather Starts?

Motorcycle stalling during cold weather starts can be attributed to the following reasons: 1. Engine oil issues: In most cases of cold-start difficulties, engine oil is the primary consideration, especially in northern regions. If the wrong engine oil is selected, it can lead to hard cold starts. The viscosity of the oil is crucial, and when choosing oil, people often prioritize cost-effective products, which can result in substandard oil entering the engine. 2. Air filter problems: Due to lack of timely maintenance, the air filter may become partially or fully clogged. The air filter functions like a human nose—once blocked, it causes breathing difficulties. As the only air intake channel, a clogged air filter not only makes cold starts difficult but also significantly reduces the engine's overall lifespan. 3. Valve clearance issues: For motorcycles that have recently undergone maintenance, cold-start difficulties are often caused by mechanics using incorrect valve clearance adjustment methods. Many mechanics rush the process and overlook a critical detail: valve clearance must be adjusted only when the engine is cold. Adjusting it while the engine is hot will have the opposite effect. Insufficient valve clearance reduces cylinder pressure, making cold starts problematic. 4. Improper carburetor adjustment: For older motorcycle models, repeated cleaning and adjustments of the carburetor can lead to accumulated issues over time, especially in the float chamber. Many riders request mechanics to tune their bikes for better fuel efficiency during maintenance. 5. Human factors: Some cold-start issues are self-inflicted. In cold northern regions, where motorcycles are often left outdoors in temperatures below -10°C, many riders use improper starting methods, such as revving the throttle excessively. During the first ignition attempt, excessive throttle can cause overly rich fuel atomization, flooding the spark plug and preventing startup.
