Natural latex recycled rubber has good elasticity and high mechanical strength, and can replace natural rubber in whole or in part to produce hair removal machine sticks. Compared with natural rubber, natural recycled rubber has low price, good plasticity, more uniform dispersion of compounds, small vulcanization return, good vulcanization flatness, small expansion and contraction of unvulcanized rubber, good aging resistance, and can replace natural rubber to produce hair removal machine sticks can not only reduce the cost of glue, but also improve the performance of processing technology and reduce production energy consumption.
1. Latex regeneration rubber index for hair removal machine glue sticks
The core requirements of hair removal machine glue sticks are high elasticity and wear resistance, temperature and water resistance, tear resistance and other characteristics, and the middle and high-end hair removal machine rubber sticks with strict requirements such as elasticity, resilience, tear resistance, and hand feel generally use natural rubber. When using latex recycled rubber E5LYY918 replace natural rubber to produce this type of hair removal machine glue stick, it is recommended to choose latex recycled rubber with a tensile strength of ≥8MPa, a tear elongation ≥of 350%, and a hardness of 50±5, which can quickly rebound and grasp feathers, reduce bird damage, have a low wear rate during continuous operation, and do not crack or degumming after repeated bending impact.
According to the color of the glue stick of the hair removal machine, choose the appropriate latex regeneration glue, generally choose white latex regeneration glue for light-colored glue sticks, easy to color matching; The black hair kneading machine glue stick uses black latex recycled glue, which is cheaper.
2. Precautions for hair removal machine glue stick manufacturers to purchase latex recycled glue
When using latex recycled rubber to reduce costs, it is recommended to purchase from a recycled rubber factory with a certain scale, with large inventory and stable quality, so as to avoid affecting normal production due to fluctuations in latex recycled rubber indicators or sudden shortages and out-of-stock; It is recommended to purchase high-quality latex recycled rubber with high glue content and few impurities, and avoid using inferior recycled rubber containing heavy metals, toxic chemicals, or too many non-rubber components.
3. Latex regenerated rubber production hair removal machine glue stick formula design points
When using latex recycled rubber to produce hair removal machine sticks, add 20-40 parts of natural rubber to improve the elasticity of the sticks; The sulfur-accelerator system can be selected for the vulcanization system, and the accelerators CZ, M, TMTD, etc. are combined with sulfur, and the dosage of the vulcanization system compound needs to be increased by about 20% compared with the pure natural rubber formula. Carbon black N330/N550 is preferred for the reinforcement system, and silica and light calcium carbonate can be used for light colors. Anti-aging agents RD, 4010NA, 4020, etc., light-colored products choose non-polluting anti-aging agents 2246, MB, 264, etc., which can effectively improve the resistance of latex regeneration rubber hair removal machine sticks to heat oxygen, water resistance, and fatigue resistance.
4. Precautions for the compounding and vulcanization process of latex recycled rubber production hair removal machine glue rods
(1) Compounding: When using latex regenerated rubber to produce hair removal machine sticks, latex regenerated rubber and natural rubber must be mixed evenly and then filler must be added to avoid over-refining and high-temperature mixing, to ensure that the compounding rubber has no particles, no white spots, and a smooth surface, avoiding the surface of the rubber hair removal stick is rough, hair removal and scraping; When mixing, the temperature of the opener is generally controlled at 35°C-55°C, and the temperature of the mixer is controlled at 105°C-120°C.
(2) Vulcanization: When latex recycled rubber and natural rubber are used together to produce hair removal machine sticks, the glue sticks are required to be dense and free of bubbles, and the vulcanization temperature, time and pressure need to be strictly controlled during vulcanization. Insufficient vulcanization temperature can easily cause the rubber rod to become soft and wear-resistant, and persulfurization will cause the rubber rod to become hard, brittle, and easy to break.
The hair removal machine glue stick is the core component of poultry slaughter hair removal equipment, and its performance directly affects the hair removal effect and the service life of the equipment. When using latex regenerated rubber to reduce the production cost of hair removal machine sticks, rubber product manufacturers must choose the appropriate latex recycled glue, reasonably determine the mixing ratio of recycled rubber and adjust the formula appropriately, and share with you the low-cost vulcanization formula of latex regenerated rubber to produce hair removal machine sticks.
