Our factory sales staff reaction, many customers use tire reclaimed rubber are used to ask the tire reclaimed rubber black content and particle size problems. In the production of reclaimed rubber products, carbon black can improve the properties of the vulcanizates and improve the hardness, modulus, breaking energy, tensile strength, tear resistance, fatigue resistance and wear resistance of the compounds; however, Screen residue, ash and moisture content of the physical properties of reclaimed rubber will have a certain impact, so the production of tire reclaimed rubber should be within a reasonable range of carbon black.
If the tire reclaimed rubber carbon black is too high, the impurity mass fraction remained within the lower range will affect the tire reclaimed rubber flex cracking resistance; carbon black water quality will affect the scorch And curing speed, so tire reclaimed rubber carbon black content should not be too high. Rubber products manufacturers in the purchase of reclaimed rubber tire, pay attention to its mechanical properties and indicators at the same time, it is best to consult the issue of carbon black content, do not plan for their follow-up procedure error incentives.
Tire reclaimed rubber carbon black content test common detection methods are nitric acid oxidation, tubular pyrolysis method, thermogravimetric analyzer, microwave cracking method, metathesis degradation method, Hongyun reclaimed rubber use professional waste tire carbon black / Carbon black content tester detects different raw materials of tire reclaimed rubber in the carbon black content.
Hongyun recycled rubber factory tire reclaimed rubber content test is through the sample under nitrogen protection, after pyrolysis gravimetric analysis obtained. After I plant (Hongyun reclaimed rubber) technical personnel testing showed that:
900 tire reclaimed rubber content of about 25% carbon black, 1200 tire reclaimed carbon content of 27%; 900-1200 tire reclaimed rubber black particle size of about 250-330.
Different brands of tires produced tire reclaimed rubber content is slightly different. (Note: The above determination of the structure for Bridgestone and Michelin tires test average, for reference purposes only.) Rubber products manufacturers in the choice of tire reclaimed rubber best time to understand the reclaimed rubber factory is used in what type of waste tires, Based on this preliminary assessment of tire reclaimed rubber carbon black content.
Hebei Hongyun reclaimed rubber factory production of recycled rubber tires, including 80 mesh ultra-fine reclaimed rubber, certified by the EU environmental protection reclaimed rubber, 16Mpa high strength reclaimed rubber, rubber products companies can choose the most suitable tire reclaimed rubber according to their own product needs Products, under the premise of ensuring the quality of rubber products significantly reduce the cost of raw materials, electricity and electricity savings.
