liquid filter bags used in Machine Coolant Filtration
As filtration
specialist, SIIC team from Shanghai Filterworkshop Co., Ltd(Shanghai Indro
Industry Co., Ltd) is very glad to share with about “SIIC liquid filter bags used in Machine Coolant Filtration”:
Old system process:
Skimmer tank—Melt
blown filter---Melt blown filter---String wound filter---CNC machine---Skimmer
tank
New system process:
Skimmer tank—Coolant
Pre Filter—Skimmer tank
In new system, during
coolant pre filter process, SIIC extend life 1 micron POXL liquid filter bags are used.
Application: Machine Coolant Filtration
Purpose of Filtration: Removal of ultra-fine glass particles, oil and other
residue
Application: CNC machining centers are used to cut laser glass for use
in defense and commercial systems. The glass must be very smooth, clean and
clear as to not distort the laser beam.
Old System: The machine coolant went to a skimmer tank to remove
oils. From there three stages of filtration were used; 50 micron melt blown
cartridge, 10 micron meltblown cartridge, 0.3 micron stringwound. The skimmer
plate was cleaned once a month and the filters were changed every day. However,
the reject rate on the glass was more than 10%.
New System: The three stages of filtration were replaced with a
single stage using SIIC extend life 1 micron POXL liquid filter bags. Filtration
life increased to 5 days.
Benefit:
--Improved yield to 95+%
--Eliminated 2 stages of
filtration – cost savings
--Extended life from 1
to 5 days
