dryer screen is a high-breathing fabric applied to the dryer
section of the long-wire paper machine and the board machine. It is
made of various plastic synthetic fibers as the main raw material,
and is processed by weaving and heat setting. Special resin
treatment is carried out as needed, and the joints of the net are
also advanced. This fabric has heat resistance, abrasion resistance
and high air permeability. It has obvious effects on saving energy
and increasing vehicle speed. The dry mesh is highly adaptable and
can be used from tissue paper to cardboard.Spiral dry mesh is made
by using the latest international non-woven technology and
equipment. mainly used in the dryness part of paper-making
machines, drying process of printing and dyeing and other
industrials.Polyester is one of the most advanced drying and filter
materials in the world. The polyester spiral dry mesh produced by
our company uses high-quality hydrolysis-resistant polyester
monofilament, which is been formed, woven, finished and
shaped.Feature1) - Polyester spiral link dryer fabric belt with
high strength,good permeability,so this fabric belt is also used
forhigh-pressure press-filter water,horizontal belt
washer,pulp-liquor separator and mesh belt coal-washer etc.2) -
This fabric belt is widely used in all kinds of industries,such as
printing and dying,food,salt
industry,pharmacy,environmentprotection etc.3) - Polyester spiral
link dryer fabric belt is also used in papermaking industry,such as
paper pulp drying,forming,and papermaking sewage treatment
etc. Polyester spiral dryer screenPolyester spiral dryer
screen can be divided into three type: 1.Small loop,
suitable for fine paper .2.Midium loop, suitable for board &
packing paper .3.Large loop, suitable for board & packing paper
. Features1. Long service life, wear resistance and low net
consumption.2. High fatigue resistance, acid and alkali
resistance.3. The surface is flat, the tensile strength
is high, the gas permeability is good, and the heat transfer
efficiency is high.4. Easy to install and use, no trace on the
interface, not easy to deform during use. UseGenerally, the
drying part of the paper machine adopts a double-row drying
cylinder arrangement.The upper and lower dryingcylinders are
equipped with a dry screen, it will presses the paper against the
surface of the drying cylinder and leads the paperruns around the
dryer.By using the temperature of the dryer to evaporate the
moisture on the surface of the paper, and then takesthe wet air
away with natural ventilation or necessary mechanical ventilation,
so the paper is dried. MaintenanceIf the paper pulp contains
a large amount of waste paper, then the cleanliness of the dry web
is very important. Some impuritiescan adhere to the dry web so that
the ability to evaporate water is limited. Make the paper web
thinner and even appears paperholes. It is recommended to clean it
in time with high pressure or with professional cleaning
equipment.Detailed Photos Company
