when your car need to painting what are you do?
when the car need to painting, i thinks as below:
The first is to purify the construction site
Before painting the car, the construction site must be inspected and treated to keep the ground clean and the wall hygienic. If it is an open-air construction site, it must be sprinkled with water to avoid the invasion of foreign sand and dust during the construction, resulting in paint film gloss and weather resistance. Sexually affected situations.
Second clean construction tool
Check the surface quality and cleanliness before painting. Before painting the car, the tools used in the construction, such as brushes, Rongpeng spray guns, paint buckets, stirs, etc., must be kept highly clean, and must not be contaminated with oil, dust, water marks, and old paint Substances that are contaminated with paint fluids. The surface quality of the car before painting must meet the specified process standard: the whole car table
Third choice of matching paint materials
When inspecting the quality of paint materials and choosing supporting materials for car painting, it is necessary to consider from many aspects: after the completion of the car product, most of the working time is outdoors, and the car paint layer must have higher protection and more Nice decoration. Therefore, it is necessary to choose high hardness, high gloss, bright colors, weather resistance, heat and humidity resistance, salt spray resistance, mildew resistance and other good performance. The choice of supporting system should be different with the main requirements of the purpose of painting. Various paints have different matching requirements, and the following two conditions must be met when considering: ① There should be good binding ability between the primer and the topcoat ② The primer and the topcoat should be adapted, that is, they must be compatible with each other.
The fourth color mixing paint and paint mixing
Dilute filtration If you need to adjust the color before construction, try a small amount of samples first. After meeting the standard color plate, expand the mix according to the proportion of the trial adjustment. You should master the gap between the wet and dry samples based on experience.
Fifth shield protection
When use Rongpeng hvlp spray gun to painting a car, most of the paint materials contain various volatile solvents that are harmful to the human body. When the concentration of these solvents is high, the nerves of the solvent have a serious stimulating and damaging effect on the human nerves, which is easy to cause poisoning. Therefore, the workplace must have good ventilation, lighting, dust removal, anti-virus equipment, and wear a variety of protective equipment, such as work clothes, gloves, masks or gas masks and protective glasses.
Heavy duty pneumatic air impact wrench tool for car wheel
In today’s world of Air tools, When you look at two impact drivers with the same price tag and one has more power than the other, you want more power, right?
High-Torque Impact Driver Pros
High-torque impact drivers can replace the need for a light-duty impact wrench
Perfectly capable of general screw driving in lower speeds
High-Torque Impact Driver Cons
Requires an adapter that breaks easily on hard metal fastening
More Torque Means More Jobs with One Tool
The most powerful impact drivers in our shootout crushed 2656 in-lbs of fastening and 4200 in-lbs of breakaway torque. A quick conversion to ft-lbs puts those figures at 221 and 350 ft-lbs, respectively.
In other words, they’re putting out light-duty impact wrench numbers. With that kind of power, you can skip the 3/8″ impact wrench and just keep a 1/2″ on hand for larger fasteners. There’s no doubt that replacing a tool increases your impact driver’s value.
The Problem With Too Much Torque
The bolt have has the certain locking force, If the powerful too big, The bolt will be broken .hurt the bolt.
When chose impact wrench , You need check the Bolt size first . check what torque you will need .Not the powerful the good
Are you think so?
