Silicone foam strip production process

by:Kenna     2021-07-12
Silicone foam strip production process, the sealing strip is a very important part of doors and windows. It can not only ensure the watertightness of the doors and windows, but also reduce the sound insulation. At the same time, it can also be protected by external forces. However, due to the usual sun exposure, it will cause aging, shrinkage or The phenomenon of deformation, therefore, we have to check regularly and look at the specific gravity. If it is of good quality, the weight will be lighter, if it is a defective product, the weight will be heavier. This is because the regular manufacturers use calcium carbonate as a filler and some manufacturers use talcum powder to increase it. The weight of the product, so we can easily distinguish good products from inferior products by looking at the specific gravity when buying. Automobile product rubber formula and its preparation method and process Background technology: At present, the low temperature performance of rubber products used in automobiles on the market is generally around -25°C, but the rubber parts on automobiles cannot withstand cold air in a harsh climate. The airflow caused the product life to be greatly reduced. The performance of rubber products used in automobiles directly affects personal safety. For example, the recall of some of the cars sold by Toyota in the past few years caused serious reputational consequences. Therefore, all automobile manufacturers need a long-term stable performance. Adequately safe rubber products. The production process of silicone foam strips is durable. It maintains stable performance and long service life in different environments. It is anti-aging, wear-resistant, does not wrinkle, stretch, and does not stick to the paint surface, and is not subject to high temperature and dust. Influencing, non-mildew and anti-ultraviolet and ozone erosion, our value to you starts from your experience. It is durable and new forever. It is the real experience of users. The beautiful coated PU sealing strip is green and environmentally friendly, and it is stylishly sealed; perfect Solve the contradiction between sealing and sound insulation, and realize the dual effect of sealing and sound insulation; doors and windows are perfectly matched with products. Among them, metal-rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be removed from the car with the same and appropriate force. The two sides of the window glass touch the glass, 3) It has an independent open-cell bubble structure, and the appearance of the special-made joint board is a honeycomb-shaped hole evenly distributed. It can be tightly bonded with cement/sealant without being roughened, and it can adapt to natural expansion. The shrinkage changes and changes to enhance the sealing, expansion, and water-stop effect of the joint. Humanization 'In the past, the tradition has always paid more attention to materials and workmanship, ignoring the attention to humanization in use. What are the performance advantages of coated seals? 1. Compression deformation test: 50% compression rate at 70°C continues to compress 22 hours, deformation rate≤10%2, compression force test, under 25% compression rate, apply a force of 15N/100mm, compression rate≤10N3, temperature range test: from -40℃ to 90℃, the sealing performance is not obvious Change 4. Heat conduction K value test: K value ≤ 0 at 0°C. Technical realization elements: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof, which has good low temperature performance and is relatively harsh in weather. Under the local environment, it can withstand the invasion of cold air and ensure good performance, thereby ensuring personal safety. Technical realization elements: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof.

Among the production process of silicone foam strips, metal rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design It is very important. First of all, the shape and size of the sealing lip should be designed. The sealing lips on both sides should contact the glass from both sides of the window glass with the same and appropriate force. 3) It has an independent open bubble structure and a special type of connection. The appearance of the seam plate is a honeycomb-shaped hole evenly distributed, and it can be tightly bonded with cement/sealant without being roughened. It adapts to changes in natural expansion and contraction and enhances the effect of seam sealing expansion and water stop. Suitable for all kinds of doors, Window, etc. 2. Cabinet sealing strip. Based on the use of electric cabinets, based on 20 years of experience in the development of sealing strips, we have developed an electrical cabinet sealing strip with its own characteristics. It has good sealing, waterproof, fireproof, and insect-proof , Windproof, light-proof, anti-collision and long service life, etc. 1. The steel frame is three-composite, not easy to deform and shrink, and the assembly is firm, and the sealing is good. 2. The sealing strip for doors, windows and curtain walls has good elasticity and durability. Migration can effectively block noise, dust, and weather. For car sealing strips, more attention should be paid to maintenance, and the correct maintenance method must be mastered, otherwise the maintenance effect will not be achieved. Let us understand together The importance of car sealing strip maintenance, the characteristics of the product The elasticity and pressure resistance of the car sealing strip are very good, and it also has good resistance to aging, ozone and chemical effects, etc., making the product in the process of use , It is very sturdy and durable, and it is also very convenient to install.
