Description
Technical field
The invention belongs to conveyer belt fields, and in particular to a kind of aramid fiber belt carcass used for conveyer belt.
Background technology
Aramid fiber has many advantages, such as that high temperature resistant, fire protection flame retarding, density are small, shrinking percentage is low, abrasion performance, resistant to chemical etching, is mesh
Strength is highest in the preceding organic fiber used, and intensity is 5-6 times of steel wire, and modulus is 2-3 times of steel wire or glass fibre, tough
Property is 2 times of steel wire, and weight is only 1/5 of steel wire or so, is the preferable framework material for preparing high-tenacity conveyer belt.At present,
Aramid fiber is mainly applied to by framework material of multilayer aramid fiber canvas in layering conveyer belt, and conveyer belt is in use, passes through
During driving drum, due to radius of curvature difference, the stress per layer material is different, so the conveyer belt number of plies the more more are susceptible to de-
Layer problem, service life is also shorter, and the bonding between aramid fiber canvas and rubber layer is more difficult.
Whole belt core conveyer belt because of its good integrity, have excellent performance, be mainly used for underground coal mine, harbour, cement, steel,
The fields transporting bulk material such as power plant.Unitary-core flame-resistant conveying belt when in use, bears load mainly belt carcass, the matter of whole belt core
Amount directly affects the quality of conveyer belt.At present, the framework material majority of whole belt core conveyer belt is the plying by terylene and cotton yarn
Line weaves for warp and weft, and longitudinal stress intensity is small；Amount containing cotton yarn is big in warp, weft, causes belt carcass thickness, inhales paste amount
Greatly, leaching paste band body thickness is big, waste of materials, while the fatigue performance of product, shock resistance, wear-resisting property are poor, make
Use short life.
