How to Deal with Windshield Oil Film?

Removing oil film involves three steps: First, use household soapy water to scrub the windshield once, which removes the actual oil film layer on the glass surface and also washes away ordinary dust layers. If ordinary cleaning is not sufficient, then hot water should be used for soaking and cleaning. The first layer can be cleaned off with regular cold water, while the second layer consists of physical adhesion or van der Waals force adsorption layers, which require hot water to be cleaned thoroughly. Hot water provides thermal energy to molecules, causing them to move more vigorously, which disrupts van der Waals forces and breaks hydrogen bonds, ultimately removing this physical adsorption layer. If there are still residues, soak the glass surface with acetic acid mixed in water and then clean it. The third layer is a chemical bond adsorption layer, usually composed of calcium-containing ash deposits or connections on the glass surface. Acetic acid, being a weak acid, can decompose most calcium deposits, finally cleaning the glass oil film completely.

What is the difference between q345a and q345b?

q345a and q345b mainly differ in their impact temperatures. Here are the specific details: 1. Grading: Q345A grade does not undergo impact testing; Q345B grade is tested at room temperature (20°C); Q345C grade is tested at 0°C; Q345D grade is tested at -20°C; and Q345E grade is tested at -40°C. The impact values vary at different testing temperatures. 2. Low-alloy steel plate: This material belongs to the low-alloy series in steel plates. Among low-alloy materials, this is the most common type. Q345 was previously known as 16Mn. The external standard for Q345 is GB709, and the internal standard is GB/T1591-94. Due to these standards, this type of steel plate is allowed to be delivered with negative tolerance.

Why does a car pull to one side?

Car pulling to one side is mainly caused by uneven road surfaces, tire pressure issues, or wheel alignment problems. If the pressure in one of the side tires is significantly low, the car will noticeably pull to that side. Other common causes include issues with front wheel toe-in and alignment angles. Below is more information about wheel misalignment: 1. When driving with the steering wheel held steady, the car should generally move straight. If it deviates to the left or right, this is referred to as pulling to one side. 2. Minor misalignment can lead to uneven tire wear or tire damage, while severe cases may result in dangerous situations such as tire blowouts or loss of vehicle control.

Are the Engines of Joint Venture Cars All Imported?

The engines of joint venture cars are not necessarily imported. With the improvement of domestic manufacturing technology, even luxury car brands such as Mercedes-Benz, BMW, Audi, and Jaguar Land Rover have embarked on the path of localization, achieving domestic production of engines and transmissions. Original imported or purely imported engines are becoming increasingly rare, and domestically produced ones are not inferior. More details are as follows: 1. The engines used in joint venture cars mainly depend on the vehicle's positioning strategy and cost considerations. Some engines are original imports, but they account for a relatively small proportion. Most involve importing original parts for domestic processing and assembly, with the final step being local procurement of joint venture brand engines. 2. Currently, domestic parts manufacturers can meet the production needs of most joint venture cars. However, for core components, joint venture companies still prefer to import parts from abroad, as it is both convenient and cost-effective.
