Rubber cork liner could be a common subway waterproof material. typically placed within the slot position of the tube. which might maintain the permanent elastic state and enough pressure . Bearing capability of the joint of the tube to accommodate an explicit. quantity of settlement of the tunnel and long crawl. The joint gap and dislocation caused by the state ensures. The waterproof impact of the joint of the section. And not solely has the perform of filling the seam however additionally relieves the native stress.
The color of the rubber sheet is black. the aim is to create varied seals and gaskets . for acid and alkali corrosion, pipes for chemical firms. Storage and waterproofing protection, and desktop birth of laboratory worktables. Dingqing rubber sheet has smart heat resistance. And its heat resistance is best than natural rubber. hydrocarbon rubber and styrene-butadiene rubber. The long use temperature will reach 100oC, and 120oC will used for forty days.
1, gas resistance is worse than atomic number 24, higher than NR
2, Through the reinforcement to offer the rubber higher physical and mechanical properties.
3. once the content of synthetic rubber is thirty ninth. The air tightness is adequate to that of IIR rubber, and therefore the air tightness is best.
4, cold flexibility
5, glorious antistatic performance
6, victimization polar lipids, plasticizing impact is best
7, smart compatibility with polar substances, like PVC, acid resin, nylon
8. The package isn’t smart. The self-adhesiveness is low. and therefore the heat generation throughout the blending method is massive.
