Product DescriptionHebei Yizhuo New Material Technology Co., LTD.,
after years of development, leading products are printing cots,
industrial cots, office automation cots three series, widely used
in printing, office automation, metallurgy, aluminum, wood,
leather, paper making, printing and dyeing industries. Our company
has 110 sets of production equipment such as mixer, dynamic
balancing machine, filter, CNC lathe and lathes, more than 800
pieces of testing equipment, rubber roller products have passed
ISO9002 quality system certification and ROHS environmental
protection certification.Industrial rubber rollers should be stored
in the temperature of 10-35ºC, the relative humidity of 50-80% of
the warehouse. The temperature is too high or too low, will cause
thermal cracking or thermal crosslinking of rubber, which will make
the rubber surface aging, hardening, loss of due elasticity,
cracking, resulting in a drop in energy; In addition, if the
humidity is too large, the damp air will cause the roller core
moisture absorption rust.Industrial rubber rollers production
processMixing is to control the content of each component, the
temperature of hot drying and so on, so that the hardness and
composition can be relatively stable. After mixing, the colloid is
not uniform due to impurities, which has to be filtered. Filtration
in addition to colloid without impurities, but also cots in the
operation of uniform force. The process of making cots and
filtering is particularly important for high-speed presses to
prevent expansion or contraction for various reasons.Then the cots
are heated, pressurized and vulcanized to stabilize the
plasticizer, so that once the rubber shrinks in the process of use,
it can reduce the shrinkage to a small degree. It can be softened
by curing, but without losing its softness, transferring ink.Then
there's the grinding and polishing. Do not require constant
temperature to perform these two steps. Otherwise, the temperature
is too low, local brittle, too high, the surface of the cots is
prone to carbonization, peeling phenomenon occurs when printing,
resulting in the decline of the cots quality, does not have its
good characteristics, can not be very good transfer of ink,
resulting in waste. These two steps are the key to determine the
quality of cots. Although the surface of the cots looks smooth,
there are still many small concave and convex parts on the surface.
Grinding and polishing is to make cots size surface smooth, so that
the ink transfer performance is good, printing quality is
high.Industrial rubber rollers storageGenerally speaking, cots
should be stored in the temperature of 10-35ºC, relative humidity
of 50-80% of the warehouse. The temperature is too high or too low,
will cause thermal cracking or thermal crosslinking of rubber,
which will make the rubber surface aging, hardening, loss of due
elasticity, cracking, resulting in a drop in energy; In addition,
if the humidity is too large, the damp air will cause the roller
core moisture absorption rust.Because the cots are covered with
rubber, in the process of transportation and storage, direct
sunlight should be avoided, rain and snow immersion, and acid,
alkali, oil and solvent contact should be prohibited, and 2m away
from the radiation heat source.Do not place in strong light and
ultraviolet light, ultraviolet light in addition to directly cause
the rubber molecular chain fracture and crosslinking, rubber
absorption of light energy and free radicals, trigger and
accelerate the oxidation chain reaction process. Ultraviolet light
acts as heating. Therefore, it is necessary to use thick paper and
black plastic cloth to cover the cots around the light protection
measures, otherwise it will cause aging, decolorization, cracking,
etc., reduce the service life of cots and affect the quality of
printing products.Cots in storage stacking, to support the shaft
storage, no extrusion stacking, roller and roller spacing should
not be less than 5mm. When handling and moving, it is necessary to
lift and hang the shaft part to prevent the rubber surface from
squeezing, knocking and scratching.If the new roller is not used
for the time being, please do not open the package, only before the
installation can take off the wrapping paper, because the wrapping
paper can play a protective role.In addition, cots should be kept
away from high-pressure equipment, motors and other places where
ozone may be produced. Because the chemical activity of ozone is
much higher than that of oxygen, it is also more destructive and
improper storage, which is easy to cause ozone cracking. For cots
stored over the standard period, check whether there are defects
before use, only in good condition can be used on the
machine.Product ParametersSizeAccording To Customer's
