High Accuracy Spinneret Plate Stainless Steel For Hollow Fiber
----- product related to various precision machining technology
By application of comprehensive precision machining technology , we
are promoting our products to superior finish and accuracy.
----- how can we supply you with spinnerets of high quality and low
combining our high precision and high efficient manufacturing
system with excellently skilled personnel , our products have won a
growing share both on domestic and abroad market due to their
----- developing new profiled hole-not- only for chemical fiber
Beginning from simple equipment made by ourselves in early years,we
never give up our effort in research for new profiled hole
processing method . today you can find us at a top position among
profiled hole spinneret suppliers.
----- Attractive capillary processing technology
Persisiting in accumulating our experience in spinnerets
manufacture for over 30 years , we have formed our own style in
capillary processing and established our advantages in this filed.
----- tool making--more accurate than others
up to now ,standardization and generalization are becoming more and
more popular. but in spinnerets manufacturing factories, how to
make special tool is still regarded as their highest secret . our
expertised tool makers provide almost all tools for ourselves.
----- smooth and finished surface processing
Surface status of spinneret contribute very much to its performance
. when you have opportunity to use our spinneret which doubtlessly
with fine surface quality, you may feel especially relaxed and
----- Strict demand on cleanning forms one fo the characteristics
in spinnerets manufacture.
Any oil stains and metal or non-metal particles remaining on
spinneret are absolutely not permitted. Our feeicient cleaning
machines can be seen at every corner in our workshop.
----- Inspection--more than recealing defects
As an important link in our quality assurance system , we
introduced numerous and various kinds of inspection instrument into
----- keeping ectending our business area
Based on our powerful capability and long period accumulated
ecperience on precision machining , we have extended our business
to the areas including electronics ,chemical engineering,etc.
cleaning of the spinnerets for melt spinning ,to clean spinnerets,
you may choose one of the following methods which we recommend:
------ Calcination: In automatic box type furnace,the spinnerets
are heated to 450-480℃.when temperature is over 480 ℃, a superheated steam will blown out the flames to lower the
temperature so that the spinnerets can be prevented from being
----- Salts Bath:Formed by NaNO3(45%)-NaNO2(45%)-NaOH(10%)in
mixture ,salts bath acts as strong oxidant at its operating
temperaturem,i.e.,450-500℃,the polymer is decomposed to CO2 and H2O
within 60 to 90 mintutes. after processed, remaining salts on
spinnerets can be washed out by hot water and oxide removed by thin
----- Procedyne fluid bed : at temperature of 450-500℃,aluminium
oxide ooeder is fludifird by hot air stream and scour the
spinnerets.polymer is detached and decomposed . carbon becomes co.
all these including inorganic substances ,such as TiO2, are
discharged in the air.
----- TEG: first put spinnerets in boiling solution which contents
NaOH(15-20%)for 2 to 3 hours to remove most of the polymer , then
in TEG bath at 260-280℃ for about 12 hours. After cooled,
spinnerets should still be washed sequentially in alkaline solution
, water and ultrasonic tank before they can be dried and stored up
.this process can avoid overheat and is suitable for any type of
stainless steel ,but need rather long time.
----- Vacuum calciner: Burning in low pressure and vacuum , most of
the polymer can be decomposed . Remaining substances are washed out
by water in the same furncace. The whole process can be auto
matically controlled and easily operated.
