Q:What kind of rubber coated aluminum alloy (metal) better
This is still a problem, the metal is with the rubber, and what rubber can wrap metal, regardless of which kind of metal can and rubber good bonding, the key is what your customers need to use what kind of rubber
Q:What is the difference between a thermoforming machine and an injection molding machine in a rubber plant?
The products produced by the thermoforming machine have low deformation rate and fixed shape. The products produced by injection molding machine have high deformation rate and have slightly different shapes.
Q:What is food grade natural rubber?
Standard rubber, natural rubber latex concentrate only and solid and liquid substances is concentrated latex by high-speed centrifuge after processing, required special barrel plus fresh, dry rubber content is 60%; the standard is a standard solid rubber rubber good solidification, machining, drying, packaging, which according to the impurity content to several levels and it has international standards, countries also have the corresponding standard.
Q:How can rubber products prevent fading?
For example, footwear product quality inspection process found in the yellowing resistance of some poor performance materials, shallow white soles during the experiment; and meet many enterprises in the production of light, white shoe sole in the process of use and storage in color yellowing phenomenon; even found some enterprises in the production of light, white sole test HG/T3689-2001 "footwear yellowing resistance test method" to determine the material in the approximation of the sun light, ultraviolet radiation resistance to yellowing ability, the observed color change of sample surface degree of occurrence is not large, but the sole is made into shoes in the process of use and storage is prone to yellow phenomenon.
Q:What kind of rubber is suitable for waterproof aprons?
The vulcanized rubber is a linear or branched structure, because of its low strength, little elasticity, hardening of the cold, softening of the heat, dissolution of the solvent, etc., which makes the products useless. Therefore, the rubber products must be vulcanized, deformed, meshed or of a shape structure to be of practical value.Proper vulcanization of the rubber can maintain the high elasticity of the rubber and the strength of the rubber. At the same time, in order to increase product hardness, strength, wear resistance and tear resistance, while adding inert filler in the process (such as Zinc Oxide, clay, chalk and barite etc.) and reinforcing filler (such as carbon black).
Q:What is the relationship between the hardness and tensile strength of rubber pad?
The molecular weight increases, increasing the fan Edward force, the chain segment is not easy to slip, the equivalent of molecules formed between physical crosslinking points with the molecular weight increased, the tensile strength increased to a certain extent reached equilibrium; the microstructure of the molecule, such as the effect of CIS and trans type structure; crystallization and orientation.
Q:Rubber and metal have to be sealed before they are too strong
Different materials and O-ring O-ring compression the change of general material such as NBR, NR, nitrile rubber, natural rubber, chloroprene rubber CR, EPDM three EPDM, HNBR hydrogenated nitrile rubber, silica gel SILICOME SBR Buna, styrene butadiene rubber, SBR, acrylate rubber ACM, compression O-ring or the 20% to calculate. If it is a special material FKM, VITON, PU, FLS silicon fluorine rubber, fluorine rubber, polyurethane, compression of these materials is calculated by 15% o ring.
Q:How to distinguish between silicone hose and rubber tube by appearance?
Smell, silicone no flavor, rubber flavor, silicone general flexibility better, rubber mechanical better
Q:What are the forming methods of rubber products?
Calendering is the process in which material is subjected to elongation. The main equipment for rolling forming is three roller or four roller calender. The three roller calender is achieved by rotating the pressure of the two roller. When the rubber material passes through the roller gap, the rubber strip is expanded into a certain sectional shape under the action of pressure, or the process of gluing is realized on the fabric. It is used for sizing, pressing, spinning, gluing and gluing of textile and steel cord, as well as the laminating of film and film, film and adhesive fabric.The basic procedure of calendering process includes: mixing and preheating glue; fabric guiding and drying (and sometimes dipping); rubber sheeting in four roll and three roll calender on or in textile and rubberized calendering semi-finished products cooling, crimping, cutting and placing etc..In rolling before the need to preprocess the rubber and textile, rubber calender before entering, to turn it in the hot refining mill, this process is called thermal refining or preheating, the purpose is to improve the mixing uniformity of refined rubber material, further increase the plasticity, increasing the temperature increase high plasticity. In order to improve the bonding performance of rubber and textile, ensure the rolling quality, need drying of the textile fabric, moisture content control in 1% ~ 2%, the moisture content is too low, the textile hardens, easily damaged during the calendering, high water content, poor adhesion.
Q:Is mixed silicone rubber dangerous?
With excellent thermal stability, high and low temperature resistance, can -60 to +250 DEG C under the condition of long-term work, ozone resistance, weatherability and good electrical properties, corona resistance, electric arc, electric spark is extremely strong, with chemical stability, weathering resistance, radiation resistance, physical inertia and good air permeability.
