Description
Technical field
The present invention relates to a kind of flexible high pressure utricules and preparation method thereof more particularly to one kind to be able to bear 10MPa high pressure
Flexible utricule, can be widely used for pressure detecting, resistance to compression shock resistance detection etc. fields.
Background technique
The purposes of utricule is numerous, and existing utricule uses the thermoplastic materials such as woven fabric coating polyester, PVC by simple substantially
Suture is prepared or is bonded after preparing sheet material using vulcanized rubber technique through adhesive, using the preparation of simple sewing process
Utricule intensity is low, and suture is easy gas leakage, and poor air-tightness, the working time is short, and uses the utricule of vulcanized rubber technique preparation same
Sample intensity is low, not withstand pressure, and safety is poor, and thickness is big after vulcanized rubber, not foldable, and storage is difficult, and there is also ageing of rubber
The disadvantages of, it is difficult to be applied to it is high-strength it is high pressure resistant, wear-resistant, air-tightness is excellent, damping, buffering performance is good, it is foldable, using the longevity
The fields such as life length.
Flexible high pressure utricule can be used for investigating the stress and strained situation of structure.Traditional anti-internal pressure test, water-filling can only
It surveys all, part cannot be surveyed, symmetrical press cannot be surveyed, big to local failure according to jack, stress is excessively concentrated, damage
Inner wall.The overall situation can not only be surveyed using flexible high pressure utricule, but also part can be surveyed, binding face consolidation, measurement result is accurate.However it is general
Logical flexible high pressure utricule usually only can provide 0.5 MPa pressure below, and application surface is relatively narrow.
Therefore it needs to prepare a kind of flexible high pressure utricule, high pressure can be provided and is able to maintain good sealing, anti-deformation behavior
Energy.
