The rubber elastic body in butterfly valves is used continuously, it will produce tear, abrasion, aging, or even perforation shedding phenomenon. The conventional thermal curing process is difficult to adapt to on-site repair needs, when repairing, use specialized equipment consume large amounts of heat and electricity, it is a waste of time but also a waste of energy.
Today phased polymer composite material alternative to the traditional method, products have excellent adhesion and excellent abrasion resistance, tear resistance, ensure that meet or exceed the repair cycle of new components, greatly reducing downtime.
