In the working process, the water hammer pump generates the water hammer effect through the mechanical action and the running water as the power. The rubber buffer block can relieve the external stress in the water hammer pump, thereby prolonging the applicable performance of the water hammer pump, generally with natural rubber. As the main raw material. The tread reclaimed rubber in tire reclaimed rubber has high rubber content and good compatibility with natural rubber. It can replace some natural rubber to produce water hammer pump buffer block and reduce raw material cost.
1. Water hammer pump buffer block formula
100 parts of natural rubber, 100 parts of tread reclaimed rubber, 4 parts of sulfur, 2 parts of accelerator, 4 parts of zinc oxide, 3 parts of stearic acid, 1.3 parts of antioxidant, 0.5 part of paraffin, 35 parts of carbon black, 70 parts of light calcium 15 parts of rubber oil; total: 334.8 parts.
2. The amount of tread reclaimed rubber in the water hammer pump buffer block
When the tread reclaimed rubber is used to reduce the raw material cost of the water hammer pump buffer block, the rubber product manufacturer can reasonably adjust the amount of the tread reclaimed rubber according to the actual demand and the specific index of the tread reclaimed rubber. Generally, 100 parts of the natural rubber can theoretically be used. -200 parts of tread reclaimed rubber, the type and amount of compounding agent in each formula are adjusted accordingly.
3. Water hammer pump buffer block formula adjustment skills
When the tread reclaimed rubber and natural rubber are used together to produce the water hammer pump buffer block, in order to further improve the physical and mechanical properties of the buffer block, the rubber product manufacturer can appropriately increase the amount of sulfur 1JLYY1025, together with an appropriate amount of accelerator D, accelerator Mzsj and rubber accelerator. DM, wherein the accelerator M can be used as a main accelerator; in the reinforced filling system, the grooved carbon black can be used together with the semi-reinforcing carbon black, and the vulcanizate vulcanizate vulcanized by the high-stretching semi-reinforcing carbon black is more elastic. Good, lower heat generation and good dynamic performance.
In the formulation of tread reclaimed rubber/natural rubber and rubber, the combination of chemical anti-aging agent and physical anti-aging agent can significantly prolong the anti-aging performance of the water hammer pump buffer block. The anti-aging agent A can be used for heat, oxygen, flexing, weathering, Fatigue has a good protective effect, and anti-aging agent D has a good protective effect on heat, oxygen and flexion and general aging.
When the tread reclaimed rubber is used to reduce the production cost of the water hammer pump buffer block, the rubber product manufacturer must select the most suitable tread reclaimed rubber product, and reasonably determine the proportion of the reclaimed rubber in the natural rubber buffer block, and appropriately adjust the regeneration. The glue water hammer pump buffer block formula strictly controls each production process, and as much as possible, the raw material cost is as simple as possible while ensuring the performance of the water hammer pump buffer block.
