Description
The spinnerets are first placed in a boiling solution containing 15-20%NaOH
for 2 to 3 hours to remove most of the polymer on the plate.The plate is placed
in a triethylene glycol solution at 260-280C,keeping for 12 hours, and then
cooled.After cooling,the spinnerets should also be processed by lye,water,
ultrasonic cleaning and drying.The advantage of this method is that the
operating temperature will not be too high,and it can be suitable for cleaning
various stainless steel spinnerets.The disadvantage is the longer cleaning
time.
Stainless steel basket for holding spinnerets.
Working Principle
Tri Ethylene Glycol (TEG) is a colorless, transparent, neutral oil liquid.
When being heated to the boiling temperature, there will be a effect of melting
and alcoholysis to the polymers. As of this characteristic, put the parts to be
cleaned into the TEG solution, heat the TEG solution to 275 °C (limit boiling
point of 286 °C ), the polymers attached to the parts will be melted.

Features
Cleaning Pot – made of stainless steel, with a cooling jacket wrapping the
barrel for cooling the temperature of TEG solution after the claening by putting
in the cooling water to the jacket and drain out in the other side.
Cover – elliptic, for gathering the vapor of TEG, intergrated with a
condenser which actually is a tube type heat exchanger. The cooling water flow
through the shell side and the vapour of TEG go through the tube side, after the
cooling, changed into the TEG solution again, and then back to the cleaning pot
from the upper flexible metal tubing.
Electric Heater– flanged type, installed at the bottom of the cleaning pot,
directly contact with the TEG solution.
Basket – made of stainless steel, customized to the parts to be cleaned,
perforated, multi-tire, and so on.
Control Panel – independent operation, auto logic programmed control of
individual cleaning pots. PID temperature control, SSR drive for heater
control.
