Sponge strips play an insulating, sealing, shock-proof, dust-proof, filling, sound-insulating, fixing and landscaping role in products from all walks of life. Sponge columns: This material is soft and flexible, has good hand feel, and can be adjusted in soft hardness. Any color and aperture The specifications can be customized. In the usual maintenance process, the following items are included. First, the detergent must be cleaned. After cleaning, it is not complete. You must also apply a layer of protective agent to prevent aging and prevent aging. dust-proof.
Liquid elastomer sealants generally have a service life of 15 to 20 years. These sealants have high adhesion and shear strength, and good softness at room temperature. The disadvantage is that the price is high, and primers are usually required. The two-component sealant is inconvenient to mix on site, sensitive to temperature and humidity during vulcanization, etc. Appearance: The surface of the high-quality NBR rubber strip is smooth and bright, the hand is soft and has strong elasticity, and the elongation is large; The appearance is average, soft to the touch, poor resilience, and low elongation.
Good air permeability ?? 6, using high-quality silicone raw materials, and after strict testing, in line with environmental standards, suitable for high temperature, high humidity, low temperature conditions, its recyclability is the main reason to be promoted, rubber and plastic Ding Qing Application and installation method of butyl rubber strip for doors and windows in rubber strips Application and installation method of butyl rubber strip for doors and windows in rubber and plastic strips: Ding Qing rubber strip is to seal a thing and make it It is not easy to open, and it has the functions of shock absorption, waterproof, sound insulation, heat insulation, dust prevention, and fixing. The effect of traction speed and flow on the state of extrusion. The analysis results of the sealing strip show that the state of the wall EtAila has a great influence. The smoother the inner wall surface of the die, the easier it is to slip. The larger the traction speed, the smaller the extrusion section, the larger the flow rate, and the larger the extrusion section. If you want to extrude a section of the same size, the adjustment of the flow rate and the traction speed conforms to a proportional linear relationship, which has important guiding significance for the actual production debugging. Although the PTT viscoelastic model is more realistic than the Bird-Carreau pure viscous model, the proportion of changes due to elasticity is small, so it is used in practical applications. Through the extrusion simulation of rubber seals with different structures, the wall slip has been analyzed in detail and important results have been achieved for complex calculation models. For example, in the optimization design of the small head, a new direction in the application of computer simulation in the field of rubber extrusion processing has been created in the domestic automotive seal industry. Under the conditions of ozone concentration pphm and elongation%, the yuan ethylene propylene rubber sealing strip can not crack for more than h. , Weather resistance (use temperature range-℃-℃), chemical resistance. After adding flame retardant, it has good fire resistance and flame retardancy. The product is processed and formed by microwave continuous vulcanization process. The surface is smooth and beautiful.
