Descripción del producto
Features:
Polyurethane foaming filling piece can prevent materials such as
coal, coal gangue falling into the needling of hydraulic
support’s big pillar, ensuring normal raise and fall and swing
the hydraulic support, helping normal repair and maintenance of
hydraulic support, and plays a good role to ensure coal mine
safety, high production and efficiency.
The product has good flexibility, surface strength and impact
toughness, with direct molding and on-site installation
available.
The core layer has good toughness and excellent compression
deformation performance, guarantee the pillar swing easily, and
can restore elastic deformation in time. The core heart’s
average density: 0.*5 g/cm3, tensile strength: **0 KPa,
elongation: **5%, 4% compression strength value: *8 KPa,
compression deformation: 8% or less.
Good impact resistances, high tear strength, and good elasticity.
The crust is about 1.**2 mm thick, under which is porous
structure. Crust density is 1.**1.2 g/cm3, whose mechanical
energy is equal to olefin plastic cortex, and puncture resistance
better than same-type plastic products. The tensile strength of
crust: ***0 KPa, breakage elongation: **0%, tear strength: 5.2
kN/m.
