Butadiene Rubber and Styrene Butadiene Rubber Hardness and Abrasion Resistance Test

Selection of rubber species: General butadiene rubber, natural rubber, styrene-butadiene rubber and isoprene rubber can be used. Using them together is more effective than using them alone. If cis-butadiene rubber or styrene-butadiene rubber is used together, although good wear resistance can be obtained, the performance is very poor, and when cis-butadiene rubber (or styrene-butadiene rubber) is used together with natural rubber, satisfactory wear resistance can be obtained. Comprehensive practical effect. Polyurethane rubber is also a kind of rubber with excellent wear resistance, which can be selected for higher wear resistance hoses. Litong has more than 10 branch service agencies in the country, not only has a service system centered on the Beijing-Tianjin-Hebei region, but also focuses on setting up offices in the Yangtze River Delta and an operation center in the Pearl River Delta, creating a market centered on engineering projects. The sales guarantee system provides exclusive products for major projects. As long as there is customer satisfaction, the team will serve you. As long as it involves fluid technology, you can see the shadow of Litong. On August 12, 2019, Luohe Litong Hydraulic Press successfully obtained the ABS product certification issued by foreign shipping companies, usually 7K, 16C, 16D qualification certificates related to oil drilling plastic hoses. Lautaro Shipping Company is one of the earliest established shipping companies in the world and has the most stringent revision standards. Everyone in the world’s South China Sea Fleet industry knows that its rigorous testing and manipulation to validate new products has achieved high worldwide results. Approved. 

 On January 6, 2020, MBA students gathered in the company’s restaurant early to participate in the recent Early childhood education theme activities. The CEO Zhao Hongliang pays attention to the company’s new year development strategy: “Management innovation, quality wins; lock first-class, education and teaching ability is above everything else; finely crafted, full of whale power; kindness and mellow, ugly words.” Yuanfa Lean Production Teacher Fan Haitao Liked the seven ways of efficient leaders: “1. Active; 2. Start over; 3. Prioritize. 4. Be able to think; 5. Understand each other; 6. Interdependence and collaboration; 7. Update again. “< /div>

PTFE is a durable consumer product with relatively low frictional resistance among all additives. The PTFE molecular structure polished in the sliding friction process will produce a smooth film on the surface of the part. It has good wettability and wear resistance in friction cutting, and PTFE is a good additive in long-term load applications. Applications for this long-term load include hydraulic piston rings, hydraulic seals, thrust washers. Moderate polytetrafluoroethylene composition is: amorphous plastic is 15% polytetrafluoroethylene, crystalline plastic is 20% polytetrafluoroethylene. The maintenance and inspection of plastic hoses for oil pipelines need to pay attention to the following matters. If there are plastic hoses that meet one of them, they should be damaged: 1. The surface is dented or distorted. 2. The stainless steel wire moves inside and outside. 3. The outer stainless steel wire is corroded or damaged. 4. The connector has fallen off or leaked. 5. Use a multimeter or a voltmeter to check the different paths on both sides of the plastic hose. 6. The connector is corroded, damaged or damaged by other external forces.
