In a rainy and humid climate, the chassis of your beloved car is most vulnerable to being eroded by rainwater and becoming rusty. Most car owners have some understanding of car chassis protection, but how to choose a chassis armor construction shop and how to identify the quality of construction are issues that广大 car owners are very concerned about.
Chassis armor construction, material and technology are the key. At present, ordinary chassis plastic sealing treatment generally only uses a single flexible resin material or asphalt material. The professional chassis armor material of 3M is composed of four products with different characteristics, and the multi-layer spraying and covering method is adopted to realize the protection of multiple functions. It has comprehensive functions of high adhesion, high wear resistance, impact resistance (high elasticity), rust and corrosion prevention, and noise reduction.
In construction, chassis armor is also particular. Whether it is a new car or an old one, first of all, it is necessary to comprehensively check the condition of the chassis, clean up dirt, rust and grease layers; use compressed air to dry the chassis; do a good job of covering the body. Covered parts: exhaust pipe, brake drum, brake, shock absorber, fuel tank pipeline, engine bottom, detachable bolts, rear axle bolts of four-wheel drive vehicles. Then start spraying construction. When it comes to spraying, it is the most critical. The distance between the nozzle of the spray gun and the construction surface of the chassis should be kept at about 25 centimeters, and move slowly and evenly to ensure the uniformity of the sprayed coating. According to different selected processes, materials with high adsorption, high strength and high wear resistance are sprayed successively. The number of times the entire chassis is sprayed is 4 to 12 times, and the drying interval time for each time is 15 to 30 minutes. After spraying is completed, the next step is to remove the cover and restore. After the chassis armor construction, driving safety and comfort can be improved, and the comprehensive functions of the beloved car can be fully reflected.
