It not only has the advantages that Woven glass cloth high temperature resistant, corrosion-resistant, dimensionally stable, elongation shrinking percentage is minimum, intensity is high,
And carpet veneer fiber is in single fiber, and three-dimensional micropore structure, porosity is high, small to gas filtration resistance, is a kind of higher speed, efficiently
High-temperature-resistant filtering material.Compared with other high temperature resistant chemical fibre felts, heatproof more high special advantage low with price, but its
Running resistance is higher than general chemical fibre high temperature filter material.
The glass fiber single filament of fiberglass needled mat is unordered staggeredly interspersed, is in omnidirectional three-dimensional micropore structure, and gap is small,
Gap rule is big, has good sound-absorbing, damping, corrosion-resistant, insulation, high temperature resistant, fire-retardant performance.Porosity is high, gas filtration
Resistance is small, and filtration velocity is big, high dust collection efficiency, while having resistant to bending, and wear-resisting, dimensionally stable fiberglass needled mat is mainly made
For the enhancing base materials for manufacturing thermoplastic sheet moulding compound AZDEL and crystalline p p sheet (GMT).In the past, glass is mainly applied
Fiber continuous needle felt, but compared repeatedly and selection, it is believed that when using glass chopped Nomex, processing performance and make
It is more preferable using fiberglass continuous needle-punched felt with performance ratio, it is mainly reflected in glass chopped Nomex and polypropylene composite materials
When, mobility is more preferable.
There are many air pockets inside small, the outstanding heat insulation material matter of the pyroconductivity of gas.Glass fibre acupuncture cotton has
Countless fine gas, and irregular alignment is presented in fiber, is splendid heat-barrier material, coefficient of heat conduction 0.2-0.040kcal/
Between mhrc；The main component of glass fibre be silicide (accounting for 50% or more), have noninflammability, without deformation, without crisp
Change, high temperature resistant reaches 7000C；When sound wave invades glass fibre cotton, phase energy is understood because of the friction with fiber and air pocket of different sizes,
And it is largely sucked.In general, acoustic absorptivity is all up to 90% or more, it is the good ability for preventing noise from interfering；Glass fibre is resistant to
High temperature, mechanicalness is good, and chemical stability is high, is optimal insulating materials；Glass fibre is not afraid of strong acid, highly basic, for a long time
Its functional characteristic will not be lowered；Glass fibre includes countless fixed air pockets, and restoration is fabulous.It is not afraid of any impact endurance test shock, tension
The equal 1.0kg or more of intensity.Hydroscopicity is usually closer to zero.Compared with other heat-insulated materials, the quality of fiberglass needled mat is most
Gently, most soft, if installation is mechanically, it can reduce the load of its weight and vibration.
Fiberglass needled mat of the invention is prepared by the following method: glass fiber being prescinded rear shredding, is inputed to
Cotton machine is sent into carding machine by predetermined volumes or weight by cotton feeder；Chopping is combed into root root monofilament on the conveyor belt by carding machine
Mat net is formed to transfer out；Mat stratum reticulare layer laying is reached predetermined thickness by lapping machine；Needing machine carries out needle thorn to feltwork, makes fibre
Dimension is mutually linked, and becomes the fiberglass needled mat with intensity；Glass mat after needle is pierced heats hot split-phase, then
It is sent into leaching in strong acid groove；Glass mat after washing with water leaching, then by containing neutralization solution processing, drying；It will do
Glass mat after dry is heated to 500-650 DEG C by heat-treatment furnace, by fabric moisture and carbon remove；Continue to heat up
To 800-1000 DEG C, sintering.
Those skilled in the art is not under conditions of departing from the spirit and scope of the present invention that claims determine, also
Various modifications can be carried out to the above content.Therefore the scope of the present invention is not limited in above explanation, but by
The range of claims determines.
