What kind of paint won't peel off when sprayed on plastic?

Plastic sprayed with air-drying acrylic paint won't peel off. This is commonly known as plastic paint. Air-drying acrylic coatings are mainly used in architectural coatings, plastic coatings, electronic coatings, road marking paints, etc. They have the advantages of rapid surface drying, easy application, and obvious protective and decorative effects. The disadvantages are that the solid content is not easy to be too high, hardness and elasticity are difficult to balance, a thick coating film cannot be obtained in one application, and the fullness of the coating film is not ideal. Characteristics of automotive paint: Automotive paint must not only have good mechanical properties, good fullness, and high gloss, but also have good adhesion, high hardness, and strong scratch resistance. At the same time, it must have good weather resistance, scratch and wear resistance, gloss durability, and excellent resistance to gasoline, alcohol, acid, alkali, and salt spray. Function of automotive paint: Automotive paint coating involves applying a film on the car's paint surface to protect the gloss of the paint from fading and to provide a physical protective film on the paint surface, thereby achieving the purpose of protecting the paint.

What Causes Low Oil Pressure at Idle Speed?

The reasons for low oil pressure at idle speed include: Malfunctioning oil pump: Insufficient oil level in the crankcase. The oil does not meet the required specifications, with viscosity being too low, meaning the oil is too thin. Effects of overly thin oil: The oil fails to meet specifications due to excessively low viscosity, or the oil level in the crankcase is too low. When the engine is idling, if the oil pressure is too low, it can lead to semi-dry or dry friction between the surfaces of moving parts, accelerating wear and tear, increasing clearance between components, and even causing bearing alloy to melt or peel off, resulting in abnormal noises. Introduction to engine idle: The oil pressure gauge reading during engine idle represents the idle working pressure of the fuel supply system, typically 0.25MPa or as specified by the vehicle's technical requirements. When testing idle working pressure, removing the vacuum tube from the fuel pressure regulator should cause the oil pressure to rise to 0.3MPa; otherwise, the oil pressure regulator should be replaced.

What is the reason for the failure of the spring brake after being flooded?

The reason why the spring brake cannot be used after being flooded: Generally, it is caused by the adhesion of the brake disc and brake pads, or rust at the fixed pin position of the brake caliper. Introduction to air brakes: Air brake is a braking method. On automobiles, a series of specialized devices used to apply a certain force from the external environment (mainly the road surface) to certain parts of the automobile (mainly the wheels), thereby imposing a certain degree of forced braking, are collectively referred to as the braking system. Automobile braking systems can be divided into service brakes (air brakes), parking brakes, emergency brakes, and auxiliary brakes according to their functions. Parking brakes can be further divided into central disc brakes and spring brakes, with the spring brake commonly known as the "spring brake". Composition of air brakes: A standard air brake system consists of the brake control mechanism, dual-circuit brake mechanism, central disc brake mechanism, brake, and air compressor. The brake control mechanism includes the brake pedal, pedal hanger, etc.; the dual-circuit brake mechanism includes the air reservoir, brake valve, low-pressure alarm, pressure regulator, brake pipe, directional valve, relay valve, safety valve, and drain valve; the central disc brake mechanism includes the parking brake control handle, brake cable, and central disc brake.

Can a Motorcycle Air Filter Be Washed with Water?

Motorcycle air filters made of sponge material can be washed with water, then dried, and a small amount of engine oil should be applied to the outer side to enhance dust filtration. However, if the filter is made of paper (some underbone motorcycles use this type), it cannot be washed. Instead, use a high-pressure air pump to blow dust from the inside out. When it reaches a certain level of dirtiness, simply replace the filter. The function of the air filter: The air cleaner consists of the filter element and the housing, with the filter element responsible for filtering the air. It removes dust and sand particles from the air, ensuring that sufficient clean air enters the cylinder. However, in many areas, the air contains high levels of dust and sand, which can easily clog the air cleaner. This may lead to symptoms such as difficulty starting the engine, poor acceleration, unstable idle, and increased fuel consumption. In such cases, replacing the air filter becomes necessary. Method for replacing the air filter: Open the car's engine hood and locate the air filter box. Some boxes are secured with screws, while others use clips. For those with screws, use a screwdriver to open them. Remove the old filter from the box, replace it with a new air filter, and fasten the clips securely.

What are the causes of rear axle hub oil leakage?

The causes of rear axle hub oil leakage include the following points: External oil leakage: Pay special attention to whether the oil seals at the front and rear ends of the crankshaft are leaking. If the front oil seal of the crankshaft is cracked, damaged, aged, or if the contact surface between the crankshaft pulley and the oil seal is worn, it can cause oil leakage at the front end of the crankshaft. If the rear oil seal of the crankshaft is cracked or damaged, or if the oil return hole of the rear main bearing cap is too small, obstructing oil return, it can cause oil leakage at the rear end of the crankshaft. Additionally, check whether the oil seal at the rear end of the camshaft is leaking. If the oil seal is aged or cracked, it should be replaced promptly. Furthermore, inspect all components of the engine lubrication system for any signs of external leakage. Oil leakage at the front and rear oil seals: If oil is seeping from multiple areas such as the front and rear cylinder head covers, front and rear valve lifter chambers, oil filter, and oil pan gasket, but no obvious leakage point can be found, check the crankcase ventilation system. Clean the crankcase ventilation pipes, especially inspecting whether the PCV valve is malfunctioning due to carbon buildup and gumming. Poor crankcase ventilation can significantly increase the pressure inside the crankcase, leading to oil seepage in multiple areas.

What are the new regulations for vehicle annual inspection?

New regulations for vehicle annual inspection: Starting from November 20, 2020, non-operational mini and small passenger vehicles with 7-9 seats (excluding minivans) within 6 years are included in the exemption range; for non-operational mini and small passenger vehicles (excluding minivans) over 6 years but under 10 years, the inspection cycle is relaxed from once a year to once every two years, meaning private cars only need to undergo on-site inspection twice within 10 years, specifically in the 6th and 8th years. Contents of the annual inspection: Check whether the engine, chassis, body, and their auxiliary equipment are clean, complete, and effective, whether the paint is uniform and aesthetically pleasing, whether major assemblies have been replaced, and whether they match the initial inspection records; Inspect whether the vehicle's braking performance, steering control, lights, exhaust, and other safety performance meet the requirements of the "Technical Conditions for Safe Operation of Motor Vehicles"; Check whether the vehicle has been modified, remodeled, or altered, whether the driving license, license plate, and all vehicle file registrations match the actual condition of the vehicle, whether there are any changes, and whether approval and alteration procedures have been completed; Check whether the license plate, driving license, and the enlarged license plate characters printed on the vehicle are damaged, altered, or illegible, and whether they need to be replaced; For large vehicles, check whether the unit name or the name of the street, township, or town where the vehicle is located and the maximum seating capacity in the cab are printed in Chinese imitation Song font on both sides of the door as required; For trucks, check whether the rear fender (including the rear fender of the trailer) is printed with the license number enlarged 2-3 times as required, and whether the word "individual" is printed on both sides of the door for individual or joint-operation vehicles; the characters must be clear, and unit codes or other patterns are not allowed (special cases require approval from the vehicle management office).
