The principle of this equipment is based on the property that polymer is cracked and coked at the temperature of 300⁰C, when isolated from air, and completely oxidized at the temperature of above 400⁰C in a small amount of air and certain vacuum environment. The cleaning process is as follow. First heating these parts up to 300⁰C in order to make polymers melt and drip to the lower chamber of collection container in the hearth, then increasing the temperature up to 400-500⁰C, in the meanwhile, turning on vacuum pump and inhaling small amount of fresh air in order that the remain polymers can be completely oxidized. After spraying water, carbon dioxide generated will be discharged out of the furnace with water.

 

The equipment is automatically controlled with the alarm function of over-temperature, lack of water or water less than standard.

 

 

 

 

The principle of the equipment is based on the property that Triethylene Glycol TEG, a kind of colorless and transparent neutral oily liquid, can alcoholysis and dissolve polymer by heating TEG in the cleaning tank up to around 280C in order to clean spinneret, spin pack, filter core, etc..

                                                        TEG Cleaning Furnace-Single Tank

                                                        TEG Cleaning Furnace-Double Tanks

                                                       TEG Cleaning Furnace-Triple Tanks

 

The process is as follow. First putting spinnerets/spin pack/filter core,etc.. in boiling solution whick contents NaOH(15-20%) for 2 to 3 hours to remove most polymer, then in TEG bath at the temperature up to 280C for about 12 hours. After cooling it, it is rinsing sequentially in alkaline solution, water and ultrasonic tank before drying and storing it up.

 

Single, double or muti-tanks are provided. The platform is equipped when using large tank diameter and high operation height. There are three choices for open/close furnace cover: pneumatic, heavy lifting device and screw device. Temperature automation control device is equipped with Japan Fuji temperature control unit and solid-state relay. All the controlling parts are made according to the requirements of anti-explosion in order to guarantee stable and reliable performance.

                                                         Water-Alkali Cleaner

 

We also provide sequential rinsing equipments, such as water cleaner, alkali cleaner, ultrasonic cleaner, etc..

 

 

 

 

The principle and process of this equipment is as follow. At the temperature of 450-5000C, aluminum oxide powder is fluidified by hot air stream and scour spinnerets, spin pack, filter core, etc.. Polymer is detached and decomposed (about 70% polymer decomposed, the rest becoming CO), including inorganic, such as TiO2, are discharged into the air.
