High-temperature Resistant Sealing and Locking Application Solution for Automobile Engine Repair
During automobile engine repair, parts such as cylinder block mating surfaces, oil circuit interfaces, and fixing screws often face problems of high temperature, high pressure, high-frequency vibration and oil contamination. Traditional sealing materials are prone to softening and cracking, and screws are easy to loosen and fall off, leading to faults such as oil leakage and air leakage, which are the core pain points in repair operations.
Pain Point Analysis of Application
- The engine operating temperature can reach 150-300℃, and ordinary sealant has insufficient temperature resistance and is prone to failure;
- The repair parts contact oil stains such as engine oil and fuel, and the adhesive force of ordinary glue decreases, leading to attenuation of sealing performance;
- Screws are affected by high-frequency vibration of the engine, and are prone to loosening and falling off, posing safety hazards;
- Fast curing is required after repair to shorten operation time and improve repair efficiency.
Adhesive Selection Guidelines
In response to the above pain points, it is necessary to select adhesives with excellent high-temperature resistance, oil resistance and locking performance. The product lines such as flange sealants and thread locking agents under Dongguan Airisen New Materials have the characteristics of long-term resistance to high temperatures above 200℃, engine oil corrosion resistance, locking and vibration resistance, and are suitable for the sealing and locking requirements of engine repair.
Construction and Testing Recommendations
Before construction, thoroughly clean the parts to be constructed, remove oil stains and dust, and ensure the surface is dry and free of impurities; select the corresponding adhesive type according to the repair parts, such as using flange sealant for flange sealing and thread locking agent for screw locking; after construction, cure as required to avoid premature stress; after repair, pressure tests and vibration tests can be conducted to initially check the sealing and locking effects, ensuring repair quality.
Purchase Communication Key Points
When purchasing, clearly inform the supplier of the specific working conditions of the repair parts, such as temperature range, vibration frequency, contact medium, etc., so as to recommend the suitable adhesive type; confirm parameters such as the curing time and temperature range of the adhesive to match the repair schedule; understand the product storage conditions to avoid adhesive deterioration affecting the use effect.
