Utilize
sack cleaner deal with containing dust gas of heavy or viscidity
relatively heavy, The dust is apt to seize the sack to be a a
troublesome problem of dust removal circle al the time. Try to cover
membrane filter bag and to filter material surface carried on
waterproof to solve preventing dew and sack pasting difficult
problem have got obvious result.

Our company
has been devoted to develop after disposing technology in recent
years, has deployed the most advanced equipment of after
disposing,the products are dealt with the crafts of buring
hair,roll,coating,drying,finalizing,etc. The after disposing level
is in a leading position at home. Waterproofly and oil-resisting
acupuncture felt produce procedure are as follows:
The fibre opens
loose-Comb-Complement net-Sting in advance-Direct thorn-Become
felts-Burns hair-Roll-Soak PTFE(waterproof pharmaceutical)-Stoving-finalize
design-Roll-Coil load .

Filter
cloth after waterproofly processing can make it water-resisting and
prevent pasting bag in using, unlikely hole blocked up and apt to
clear dust havingproperty
of acid-resisting and alkali-reisiting
|
|
The filter bags
through waterproof and oil-resisting are applied to wet quantity
heavy occasion compared with ordinary filter bag as filter material
is difficult to block up pasting bag,so service life lengthens and
clear gray cycle can be lengthened of the sack,the flow of gas
passed is strengthened too, so can save a large amount energy
consumption and safeguard expenses, increased the output at the same
time.

The after disposing technology of our company
can no only process the ordinary acupuncture felt(suck as
Dacron,polypropylene fibre,defend static,meishida), but also
waterproof and oil-resisting of the dacron 208 flannel,729 cloth,
etc. of machine material
