Rubber plucking rod is made of rubber as the main raw material, mainly used to remove poultry feathers of rubber products, using the elasticity and friction of rubber to pull out feathers, generally with natural rubber, styrene-butadiene rubber and other main raw materials processing. Latex reclaimed rubber is waste natural rubber, waste latex and its products are manufactured by sorting, crushing, desulfurization, filtration and other processes, the main component is rubber hydrocarbons, which can replace natural rubber for the production of rubber plucking rods, effectively reducing the cost of raw materials.
1. The application of latex reclaimed rubber in rubber dehairing rods
Latex reclaimed rubber has good compatibility with natural rubber and styrene-butadiene rubber; Compared with natural rubber, latex reclaimed rubber has better plasticity and fluidity, and good aging resistance. Latex reclaimed rubber/styrene-butadiene rubber, latex reclaimed rubber/styrene-butadiene rubber/natural rubber combined rubber can be used for the production of plucking rods. The combination of natural reclaimed rubber and styrene-butadiene rubber to produce rubber plucking rods can effectively reduce the cost of raw materials and improve the wear resistance, aging resistance, flexural resistance and heat resistance of the plucking rods; The appropriate amount of natural rubber can further improve the elasticity and flexibility of the plucking rod.
2. Rubber plucking rod with latex reclaimed rubber selection skills
The rubber plucking rod needs to be repeatedly deformed during use, and the raw materials are required to have good elasticity and flexibility to ensure that the feathers can be effectively clamped and smoothly removed during the plucking process; The plucking rod will frequently rub the feathers and skin during use, and the rubber material is required to have a certain degree of wear resistance.
When using latex reclaimed rubber to replace part of natural rubber to produce rubber plucking rods, it is recommended to choose latex reclaimed rubber with high rubber content, such as Hongyun 100% black latex reclaimed rubber, which has high effective rubber hydrocarbon content, high strength, good elasticity, wear resistance and flexural resistance, which can provide better elasticity and wear resistance for plucking rods. Compared with the white latex reclaimed rubber with the same index, the price of black natural reclaimed rubber is lower, and it can reduce the cost of more raw materials when used in the processing of black rubber plucking rods.
3. Latex reclaimed rubber / styrene butadiene rubber / natural rubber and use the production of rubber plucking rod formula adjustment skills
When latex reclaimed rubber replaces part of natural rubber to produce plucking rods, it is recommended to appropriately increase the amount of vulcanizing agent and accelerator in the formula to ensure that the rubber is fully vulcanized; Appropriate use of high wear-resistant carbon black to improve the wear-resistant performance of the plucking rod (the hardness of the plucking rod needs to be moderate, too hard is easy to damage the skin of poultry, too soft to effectively pluck the feathers, so the amount of carbon black should not be too high); Choose the right antioxidant to prolong the life of the plucking stick.
4. The effect of vulcanization time on the performance of rubber plucking rods
The vulcanization time is too short, the cross-linking density is low, and the cross-linking structure among rubber molecules is insufficient, resulting in insufficient strength, hardness, elasticity and flexibility of the plucking rod, which is easy to tear or deform, and it is difficult to effectively pluck the hair; If the vulcanization time E4LYY715 is too long and the cross-linking structure is too long, the rubber may become too hard, and the elasticity and flexibility of the plucking rod will be reduced, resulting in the plucking rod being easy to break when used. Improper vulcanization time may lead to cracks, bubbles or uneven vulcanization on the surface of the plucking rod, affecting product quality.
When using latex reclaimed rubber/styrene butadiene rubber, latex reclaimed rubber/styrene butadiene rubber/natural rubber and glue to produce plucking rods, the vulcanization time directly affects the performance of the finished product. A reasonable vulcanization time is the key to ensure the performance of the plucking stick. The determination of the vulcanization time needs to be combined with the vulcanization temperature and pressure to ensure that the positive vulcanization state is reached; In the future, Xiaobian will share with you the key points of the mixing and vulcanization process of latex reclaimed rubber production.
