Rubber threading coil and rubber threading sheath are two common products in rubber products: rubber threading coil, also known as rubber threading ring, is a ring-shaped rubber seal, and the hollow ring part is used for socketing and Seal the wire or cable; the inner diameter of the rubber threading coil matches the outer diameter of the wire, which can be waterproof and play a role of protection and insulation. The rubber threading sheath is a rubber product that is wrapped around the wire or cable for protection and insulation; the rubber threading sheath is generally in the shape of a round tube with a certain length and wall thickness. When producing rubber threading coils and rubber threading sheaths, some tire reclaimed rubber is added to reduce costs, but when tire reclaimed rubber is used to produce rubber threading coils, the following items need to be paid attention to:
1. Quality of recycled materials: Due to the uneven source and quality of recycled materials, strict screening is required when selecting raw material suppliers, and testing and analysis of incoming raw materials are required.
2. Formulation design: According to the product performance requirements and the use environment and other factors, the formula is reasonably designed. At the same time, it is also necessary to properly adjust the composition ratio for different types of rubber threaded coils to ensure that its mechanical strength, corrosion resistance, and oxidation stability perform well.
3. Production process control: In the process of processing, temperature, time, pressure and other parameters should be strictly controlled to ensure stable and reliable product quality.
4. Quality monitoring: conduct a comprehensive test on each batch of seals produced and record relevant data, including visual defect inspection, physical performance testing (such as hardness, tensile strength and tear resistance), chemical characteristic evaluation (such as hydrolytic stability) and other indicators to ensure that the product meets the standard requirements.
5. Safety protection: Pay attention to safety protection during operation, such as wearing gloves, goggles, etc., to avoid injury caused by material splashing.
In the process of manufacturing rubber threaded coils, it is necessary to pay attention to the quality of raw materials, formula design and production process control to ensure stable and reliable product quality; if the products are exported to EU countries, they must also meet the requirements of relevant standards.
Formulation of tire reclaimed rubber to produce rubber threading coil or sheath 29E3Y5y:
Mixing mixer: 5kg styrene-butadiene rubber, 35kg reclaimed tire top tire rubber, 3.5kg N330 carbon black, 15kg light calcium carbonate, 0.2kg paraffin, 0.4kg stearic acid, 0.6kg polyethylene glycol , 4010 anti-aging agent 0.25kg; Coumarone 1kg
Mixing mill feeding: zinc oxide 0.7kg (can also be added at the end of banburying), CZ accelerator 0.18kg, DM accelerator 0.18kg, TMTD accelerator 0.04kg, sulfur 0.4kg
Pay attention to controlling the temperature after feeding the internal mixer, preferably around 80°C for internal mixing; the vulcanization temperature is 145°C, and the vulcanization time is adjusted according to the product model size.
Compared with natural rubber and synthetic rubber, the production of tire reclaimed rubber for rubber coiling has the following advantages HYZSJ:
1. Environmental protection: recycled rubber processed from recycled materials such as waste tires can effectively reduce resource consumption and environmental pollution.
2. Lower cost: The use of tire recycled rubber materials can reduce costs to a large extent and improve economic benefits on the premise of ensuring quality.
3. Good quality stability: The regenerated tire rubber after fine treatment by modern equipment has stable quality and reliable performance, and it performs well in terms of mechanical strength, corrosion resistance and oxidation stability under appropriate conditions.
4. Better plasticity: tire reclaimed rubber has a certain degree of plasticity after multi-channel crushing, screening, desulfurization and other methods. It does not need to be masticated like the original rubber, saving electricity costs.
In practical application, tread reclaimed rubber to make rubber coils has certain advantages in terms of cost, environmental protection and stable quality, and it is widely used in the field of ordinary rubber products.
