- Q: What are the application fields of waste tire rubber powder?
- Waste tire rubber powder modified asphalt for highway, waterproofing materials, modified concrete, modified coating, railway sleepers, rubber brick, machine pad, cushion, cushion and other types of subgrade gasket and fenders, sound-absorbing materials, road sealant, shoes, carpet padding, tire pad, car body, bottom sealing rings miscellaneous pieces of rubber, etc..
- Q: How to make mobile phone rubber coat non stick ash?
- Stained with ash is not terrible, with a period of time you can use clean water with a small amount of detergent, wash it; if the stain is very serious, you can use alcohol wipe, and then clean with water.
- Q: What advantage does ethylene propylene rubber with three yuan compare to two yuan ethylene propylene rubber?
- In recent years, the third monomer and new technology development, foreign developed 1 7- octadienoic, 6, 5, two 10- methyl -1, 9- eleven, 7- two three ene 3, methyl -1, 6- octadienoic, 5 7-, two methyl -1, 6- octadienoic, 7- methyl -1, 6- octadiene as the three EPDM third monomer, the performance of three Yuan rubber has been enhanced. The monomer and content of third monomer in three yuan ethylene propylene rubber have direct influence on vulcanization rate and vulcanizate property. Among them, dicyclopentadiene (DCPD) as the third monomer, although the price is low, but the three Yuan rubber vulcanization speed is slow, difficult and high degree of unsaturation diene rubber and use; to ethyiidenenorbomene (ENB), 6 10-, two methyl -1, 5, third monomer three Yuan rubber vulcanization speed 9- eleven three ene as fast, the former has become the main varieties of three yuan of ethylene propylene rubber. The third monomer content in iodine said three EPDM iodine value is generally 6-30, mostly around 15. The iodine value is 6-10, curing speed is slow, difficult and high unsaturated rubber; iodine value is 25-30, for ultra high speed curing type, available in any proportion and high unsaturated diene rubber and use. Therefore, three yuan ethylene propylene rubber and other rubber in use, should pay attention to choose the appropriate three yuan ethylene propylene rubber varieties.
- Q: How to test the abrasion resistance of rubber?
- As long as the amount of carbon black is added, the wear resistance will be increased. Have the Akron abrasion resistance test (the rubber disc shape small rubber wheels on the wheel rotating friction, turn a lap after the contrast test before and after the rubber wheel quality, poor quality of smaller, better resistance).
- Q: How can rubber and mould not be bonded when producing rubber products?
- Rubber is soft nature of the product, the draft (draft angle) is not to die. In other words, theoretical deduction is possible. However, the complex structure, a little larger, and often die adhesion is difficult to remove, and part of the solution can be solved with release agent.
- Q: Aging of rubber parts for automobiles
- Due to the comprehensive effect of various internal and external factors, rubber products will deteriorate the chemical properties and mechanical properties of this kind of phenomenon is realized by rubber aging, cracking, sticking, hardening, powder, mold. Shute rubber reminder, especially the rubber parts on the vehicle, due to the complex use of the environment, aging accelerated more obvious.
- Q: Is the odour emitted by industrial rubber poisonous?
- The rubber shaped blank after extruding; and then the textile materials and rolled hanging glue or glue (or metal) together formed into semi-finished products; finally after vulcanization will have final semi-finished products made of high elastic plastic.Most of the ingredients are organic substances, volatile, containing toxic, harmful and highly carcinogenic NOBS.
- 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: How to clean rubber products?
- Rubber products are made of rubber raw materials and made from mixing rubber and mixed rubber as raw materials. When the rubber is mixed, the formula is designed according to the characteristics of the required rubber products, and the hardness of the products is determined. The product is made and molded by rubber flat vulcanizing machine. Finally, the product is processed by flying edge, and the surface of the product is treated smoothly without burrs.
- Q: What's the difference between natural rubber and three yuan ethylene propylene rubber?
- Vulcanized natural rubber elastic rubber and its crosslinking density is not too high, the elasticity is high. For example, in the range of 0-100 DEG C, elasticres at 50-85 DEG C, the elastic modulus of steel is only 1/3000, the tensile elongation is up to 1000%, to 350%, after retraction of permanent deformation is only 15%, a higher elasticity of natural rubber in the general rubber after polybutadiene rubber.
