Ceramic Fiber Products
Ceramic fiber product is manufactured
from high quality pure ceramic fiber. Which classify temperature included
1260¡ëC and 1430¡ëC. Series product from bulk, yarn, cloth, tape, round
braid, square braid, ladder tape, twisted rope, blanket, felt, paper,
board, module, tubing, sleeving, etc. they reinforced with glassfiber,
stainless steel wire or inconel wire.
All of them are free of asbestos.
Ceramic fiber is ideal product used in asbestos replacement, high
temperature furnace, flue line insulation and refractory.
Ceramic fiber contains approximately 18% organic fiber, which burns out at
high temperature. But has no effect on the properties of the products.
Applications:
1) Heat insulation materials for covering
2) Spark receiving sheet, protective clothing, gloves, helmet, boots
3) Heat insulation in industrial furnaces, furnace curtain, furnace door
gaskets
4) Composite friction brake liner
5) High temperature pipes and vessels insulation, Flue liners
6) Diesel engine exhaust wrap, vehicle engine heat insulation cover
7) Cable covers and cable tray insulation, electrical insulation
8) High temperature valves and flanges sealing
9) Fireproof door, fireproof curtain, Fireproof blanket
10) Molten metal filter
11) Extreme low-temperature containers heat insulation wrap
12) Aircraft heat insulation material
13) Substitutes for asbestos textiles and other similar products with
higher
temperature
14) Fireproof to be used in the kitchen
High Temperature Yarns
#
Fiberglass Yarns
E-glass single yarn is suitable the domain to include: electron insulation
material, electronic industrial fabric and other industry fabrics. It
represents the profession: the electron industrial glass fiber fabric (CCL,
PCB, PWB) and anti- burn insulating glass fiber fabric.
Silica yarns is a special fiberglass yarn which contains more than 96%
silicon dioxide, loss on Ignition <10%. With excellent heat resistance, it
can work at the temperatures of 1000 centigrade degrees for about an hour
and withstand at the temperatures of 1800 centigrade degrees for
short-time .
High temperature yarn is composed of amorphous silica continuous filament
fiber.
Applications:
Silica yarns is used in applications requiring small diameter materials
that resist high temperatures, electricity, and the effects of many
corrosive substances.
# Ceramic
Fiber Yarn
It is manufactured from high quality
ceramic fiber. It has been mechanical twisted to give it tensile strength.
Ceramic Fiber yarn is available as E-glass, stainless steel wire or high
temperature Inconel alloy wire reinforced yarn from 525 Tex up to 2500 Tex
in two or three plies of single yarn twisted together in order to form a
heavier yarn or higher strength.
# Carbon Fiber Yarn
Carbon tow; carbon fabric, chopped carbon fibers; milled carbon fibers,
carbon veil; carbon powders; Carbon fibers are made by converting
Polyacrylonitrile fibers under heat and pressure into high strength, high
modulus carbon fibers.
These carbon fiber are then further processed and converted into:
The carbon fibers contain high strength-to-weight and stiffness-to-weight
ratios, carbon fabrics are thermally and electrically conductive and
exhibit excellent fatigue resistance. When properly engineered, carbon
fabric composites can achieve the strength and stiffness of metals at
significant
weight savings. Carbon fabrics are compatible with various resin systems
including epoxy, polyester and vinyl ester resins.
Carbon fibres inherently are high in tensile and flexural strength,
tensile and flexural modulus, conductive, inert to most chemicals, light
weight, and as such, they are widely used in the following application:
Alumina-Silica Fiber Yarn is composed
of Al²O3(alumina) and SiO2(silica) which is available in combination of
A/S=60/40,72/28 & 80/20.
ALF Ceramic Fibers are refractory
alumina-silica fibers with diameters 7-10 microns.
A/S 60/40 can continuously withstand
temperatures up to 1200 º C.

Silicon Carbide Yarn Stimulates
Development of New Composites
The creation of new types of fibers has, in the past, stimulated the
development of equally new composites. Besides the most commonly used
glass and graphite fiber types, a number of newer ceramic fibers have been
introduced: Fiber FP by DuPont and 3M Company's Nextel are two recent
examples. In addition, a silicon carbide yarn is currently available from
the Nippon Carbon Company of Japan. This last fiber, called Nicalon, has
created a great deal of interest because of its unique suitability for
reinforcement of resin, metal, and ceramic matrix composites. I will
briefly describe some of the characteristics of this ceramic yarn and the
composites that have been fabricated with it. While these data are of
interest, it is probably more important that this fiber has stimulated
wide enthusiasm for fibers and ceramics created from organometallic
precursors.
