The use of tire reclaimed rubber to produce rubber products can significantly reduce the cost of raw materials, in which the production of ordinary rubber hose is a major application of tire reclaimed rubber. Whether it is the use of reclaimed rubber or raw rubber production of rubber hose often appear shiny surface phenomenon, affecting the appearance of the product. When using rubber reclaimed rubber hoses, how to make the hose products shine bright and shiny is a problem that many hose manufacturers consider. If you have time, let's see how our technicians make the hoses “bright”!
Usually caused by the rubber reclaimed rubber produced by the surface of the hose is not enough gloss, or even bumps, there are three main reasons: First, tire reclaimed rubber product mold is not smooth. Second, the fineness of the tire reclaimed rubber products is not enough, and then the problem is that the ratio of the tire reclaimed rubber hose formula is incorrect, which leads to unsatisfied vulcanization. We can analyze the specific problems specifically, according to its law.
1, choose a high degree of smooth mold, and timely cleaning, conservation, to ensure the smoothness of reclaimed rubber product mold to avoid the production of the surface of the hose because the mold is not smooth or contain impurities and uneven phenomenon, the smooth surface of the hose appearance, "sell" more it is good.
2, from the point of view of the production process, for the tire reclaimed rubber hose in the larger particle size of the compounding agent in advance grinding, and reasonable control of the processing temperature; commonly used high-temperature curing hose surface is more smooth.
3, from the raw material point of view, in the cost allows the conditions, as far as possible the use of finer tire reclaimed rubber products. General thickness of the hose in the 3-5MM to use more than 60 mesh of tire reclaimed rubber, if 2MM at least with the 80-head tire reclaimed rubber production of the hose is bright, the thinner the hose used tire reclaimed rubber fineness requirements high. The tire reclaimed rubber hose products produced from high-quality, high-quality tire reclaimed rubber products are even brighter and brighter.
4, from the formulation point of view, by adjusting the formula in the mix to increase the brightness of the hose, such as increasing the rubber hose (you can use the tire reclaimed rubber containing the highest amount of tire top reclaimed rubber, can also be used in tire reclaimed rubber hose A small amount of natural rubber) or increase the amount of resin added, increase the density of carbon black and so on.
5, in the above conditions are available, reclaimed rubber hose product gloss is still not enough, we must consider adding a small amount of rubber brightener in the production process of the hose, increase the surface of the hose light, can significantly improve the surface gloss of the hose, and Hose performance does not have any effect.
Is there any better way to improve the brightness of rubber reclaimed rubber hose?
