How to make a silicone foam test report

by:Kenna     2021-07-12
How to make the test report of the silicone foam strip, the auxiliary seal of the compensation ring is a metal bellows, called the bellows mechanical seal, 2. The composition of the mechanical seal: There are mainly the following four types of parts, a, the main seal: moving ring and static Ring, b, auxiliary seal: sealing ring, c, compression element: spring, push ring, d, three, and put the PVC sealing strip and silicone rubber sealing strip in the freezer compartment of the refrigerator at the same time, leaving it for several hours, PVC sealing strip It will feel very stiff, easy to break, and the physical properties of the silicone rubber sealing strip will not change. 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. How to make the inspection report of silicone foam strips In the raw materials for the manufacture of sealing strips, EPDM rubber, the main raw material used in the past, is also constantly updated and developed. It has excellent physical properties and a new type of EPDM controllable molecule with good processing properties. The medium and long chain branching makes it better vulcanization performance, and can increase the extrusion speed and product output. These materials not only have the excellent engineering performance of elastomers, but also have the excellent characteristics of plastics, which are convenient for processing and recyclable. Utilization, these materials are gradually replacing EPDM products. Moreover, the design of this EPDM sealing strip is often more advanced. It has an independent bubble structure, so that it can form a good sealing bond rate, and all the bubbles have reached uniformity. The distribution of it can play a very good performance of expansion and contraction. It is precisely because of this that it can achieve the superior performance of no flow, no deformation, no cracking, etc. in use, except for the plane on the contact material used. , Can not be combined with many uneven materials. Doors and windows bring light and vitality to the room. Doors and windows extend the limited space infinitely. Said ternary bc sealing strip (rubber EPDM)-suitable for special environments at -40°C-+160°C, and has superior ozone resistance Characteristics and anti-purple light characteristics and chemical solvent resistance characteristics, far beyond similar products, widely used in vehicle seals and building seals, in addition to various physical and chemical performance indicators in the field, our company has developed and designed hardy and heat for different fields of use. It also delivers foam and solids, with special properties that can meet the needs of the application. Technical realization factors: 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, can withstand the attack of cold air in a local environment with relatively bad weather, and guarantees good performance. Ensure personal safety.

Ensure personal safety. How to make the test report of silicone foam strips. In addition, the material proportion of this type of product (above 1, 4) is equivalent to that of PVC (low-end vulcanized EPDM strips have a greater proportion). The window rate is similar to that of PVC strips, and the cost of use is Relatively high, it is difficult for door and window companies to accept. Sealing strips can be classified according to several methods such as cross-sectional shape, vulcanization method, application location and purpose, and materials used. Product characteristics 1) Light bulk density, high expansion and contraction strength, and no water absorption (instead of traditional Three oils and four felts, asphalt wood fir board and other materials). Where can it be used? Wooden windows, aluminum-clad wood, aluminum alloy doors and windows, wooden doors, wood-plastic doors, ecological doors, log doors, solid wood doors, painted doors, oak doors, composite doors, suit doors, security doors, sliding doors, wardrobe doors, cabinet doors, Bronze doors, cast aluminum doors, plastic steel doors and windows, etc., 035W/m2K; 5. Fatigue resistance test: imitating window opening and closing 500,000 times, no obvious change in shape 6. Sound insulation test: only IV68 windows with intermediate rubber strips, reducing noise 43 7. The IV76 window with intermediate and additional adhesive strips can reduce noise by 45 decibels. 8. Outdoor aging resistance test: It has been more than 20 years and the performance remains intact. The series of products are environmentally friendly products and do not contain CFC harmful substances. Wooden door, door and window sealing strip product features: self-adhesive wooden door sealing strip is made of EPDM rubber foam, which creates its excellent characteristics, door and window sealing strip characteristics, plastic steel door and window sealing strips are widely used in recent years, a new generation Doors and windows have better corrosion resistance, weather resistance, noise reduction and heat insulation than ordinary door and window sealing strips. The rubber materials of the sealing strips are more resistant to aging, low temperature, moisture, and chemical corrosion, especially ozone aging. Ethylene propylene diene rubber (EPDM). Technical features: 1. An automobile product rubber, characterized in that the automobile product rubber is composed of EPDM, carbon black, softening oil, processing aids, and accelerators.
However, rubber seal strip suppliers isn't the only producer in domestic, and many people feel that Guangzhou Kenna Rubber & Plastic Co., Ltd.'s service leaves much to be desired in terms of functionality and design.
If you have any issues with your rubber seal strip suppliers, you will have to call the experts at Kenna Rubber & Plastic to assist you. Any of your enquiry is warmly welcomed.
Guangzhou Kenna Rubber & Plastic Co., Ltd.’s model also predicts (i) a positive effect of management on firm performance; (ii) a positive relationship between product market competition and average management quality (part of which stems from the larger covariance between management with firm size as competition strengthens); and (iii) a rise (fall) in the level (dispersion) of management with firm age.
While the productivity and efficiency benefits of automation are unequivocal for manufacturing rubber seal strip suppliers, the need for skilled humans to operate, utilize and advance technologies is equally unmistakable.
