China Unique Wear-Resistant Rubber by Liquid Phase
Wide Application in Pumps, Valves and Cyclones
Equipment Service Life Prolonged Greatly
Slurry pump---light rubber impeller, energy saving and low power consumption; rubber wet parts,
prolonging equipment service life
Valve---high elastic rubber liner, gate valve and gate plate coupling tightly, strong sealing, and
long service life
Cyclone---lined with Xinhai wear-resistant rubber which prolongs the service life more than 1
times
The Wear-resistant rubber Test Room of Xinhai Group Rubber Institute comprehensively tests properties of
rubber
Abradability Test
A Comprehensive Testing of Rubber Wear-resistant Performance
Abradability is directly related to the service life of rubber and the first index of rubber
performance
Test results: Xinhai wear-resistant rubber life is several times longer than other rubber life
Tensile Test
Test the Limit Tensile Performance of Rubber
Rubber tensile performance is an important index to judge the quality of rubber
Tensile test result
Elongation：825%
Tear strength：75dN/mm
Rubber hardness：37 Shore A
Special Rubber Process by Liquid Phase
Liquid Phase Nanometer Compounding•Normal Temperature High – frequency Curing
Xinhai Group Rubber Institute successfully developed the technology named Liquid phase nanometer
compounding•normal temperature high – frequency curing after continued efforts which broke up more
than 80 years' monopoly in rubber field by a foreign company.
Xinhai wear-resistant rubber produced by this process takes the leadership in wear-resistance,
resilience and tear resistance etc.. This process is involved in the science and technology
development plan of Yantai city by Yantai Science and Technology Bureau in 2013.
Xinhai Wear-resistant Rubber Liquid Phase
Every Advanced Step Creates the Best Quality Wear-resistant Rubber
The natural latex and Xinhai liquid nanometer additives are mixed in liquid to guarantee the minimal
additives keep the content of natural rubber.
② Normal temperature liquid mixing
Fully mixing in normal temperature and liquid, no mechanical cutting, ensuring the structural
completeness of rubber molecular!
③ Mixing rubber blank
High quality rubber blank without solidification drying, banburying and mixing process which damage
rubber molecular chains
④ Normal temperature and high frequency vulcanizing
Xinhai has China maximum custom high-frequency vulcanizing machine (9.26 * 1.26), vulcanizing more
uniform in room temperature and shorter time taken, which guarantee the quality of rubber!
⑤ Rubber product
China unique wet type rubber, the international advanced quality, natural rubber content up to 97%,
slurry environment preferred!
⑥ Rubber roughening
Professional rubber roughening machine independently researched and developed by Xinhai ensures
wear-resisting rubber liners and equipment bond more tightly.
Rubber Honors
China Unique Wear-resistant Rubber by Liquid Phase
Xinhai wear-resistant rubber has been widely recognized by the society by unique rubber
international leading technology. On September 28, 2013, the scientific and technological
achievements appraisal conference about this process was held in Yantai Economic and Technological
Development Zone, and at the same time, the technology has been involved in the science and
technology development plan of Yantai.
On October 22, 2013 the Trelleborg Group Australia President Bruce Cage, the Holland area technical
director Gert Smit and Trelleborg engineer systems (Qingdao) Limited General Manager Huang
Shaoxiong, visited the Xinhai Group to investigate wear-resistant rubber, hydrocyclone and other
rubber products. The Trelleborg Group has become an important cooperative partner of Xinhai
wear-resistant rubber!
