Now with the continuous advancement of the production process of latex reclaimed rubber, the quality of latex reclaimed rubber products is getting better and better. More and more enterprises are using latex reclaimed rubber instead of natural rubber to produce rubber products, which can not only guarantee the quality of rubber products, but also Reduce the cost of raw materials, why not? However, careful friends will find that the index of summer latex reclaimed rubber is different from that of latex reclaimed rubber in winter. Why?
The main factors causing the change of latex reclaimed rubber in winter and summer are the changes of ambient temperature and humidity. The following three indicators will change:
1. The hardness of latex latex in summer is low, and the hardness of latex latex in winter is high. (In actual storage, all the hardness of reclaimed rubber will change within a certain range, but the hardness of latex reclaimed rubber changes most obviously).
2. Tensile strength is the ultimate ability of reclaimed rubber products to resist tensile damage. Generally, the higher the rubber content, the greater the tensile strength of latex reclaimed rubber. For example, Hongyun black natural reclaimed rubber with Malaysian latex yarn and variegated waste latex gloves. As raw materials, the tensile strength of the product is about 16.5Mpa; but the tensile strength of latex latex in summer will be about 1Mpa lower than that of winter products.
3. The elongation at break of reclaimed rubber refers to the ratio of the elongation of the test piece to the original length until the breakage. The elongation at break of the latex reclaimed rubber is not only related to the raw materials and formula, but also related to the season. The elongation at break of reclaimed rubber will be about 10% higher than in winter.
In addition to the differences in indicators, summer latex rejuvenation adhesives will have a stronger rubber smell due to the hot weather, while cold winter latex rejuvenation adhesive smells will be relatively light. These are the differences between summer latex reclaimed rubber and winter latex reclaimed rubber. According to the different characteristics of the two seasons of latex reclaimed rubber, we need to timely adjust the formula of reclaimed rubber products, mainly from the following aspects:
1 The amount of fat in the summer reclaimed rubber formula can be appropriately reduced, and the amount of fat in the winter reclaimed rubber formula is increased in an appropriate amount; 2 The content of carbon black in the summer reclaimed rubber formula is slightly increased, and the content of light calcium carbonate can also be increased in an appropriate amount. In addition to the recipes, since the temperature difference between warehouses and production workshops in winter and summer is relatively large, it is best to use latex reclaimed rubber in advance to park the latex reclaimed rubber in a warm room for a period of time in advance, and adjust the rubber production appropriately. Vulcanization temperature and curing time.
Hebei Hongyun reclaimed rubber production of latex reclaimed rubber containing high amounts of rubber, the price concessions, the replacement of natural rubber production of rubber products can guarantee product quality, can also reduce raw material costs, improve processing performance, improve the rubber product's own anti-aging properties, quickly Hey!
