How to use

Note: The operator wears a self-absorbing filtered dust mask, chemical safety glasses, toxic-proof work clothes and rubber gloves.

A: Preparation of triethylene glycol diacetate plasticizer

2022051702 2Take 54.95% of triethylene glycol, 45% of acetic acid, 0.05% of sulfuric acid or p-toluenesulfonic acid, put it in the sandwich reactor and heat esterification, the temperature is 90-130℃ under normal pressure, dehydrate continuously, add 2-5% of acetic anhydride, react again for 30 minutes, evaporate its water and acetic acid under reduced pressure, reduce the reaction solution to 30 -40℃, add 10-15% sodium carbonate aqueous solution to neutralize to pH7.0-7.5, then add 30-50% salt water, stir and leave to stratify, separate out the triethylene glycol diacetate layer, dehydrate under reduced pressure, add 1 – 8% activated carbon is added to decolorize the product, and then pressed and filtered to obtain triethylene glycol diacetate used as plasticizer for vinegar fiber filter nozzle.

B: Preparation of high-matching quality melt by alcoholysis of waste polyester textiles with triethylene glycol

2022051702 3The melt viscosity of the melt from the screw extruder is 0.40~0.50dl/g, and then the melt viscosity of the melt from the tempering and viscosity adjusting device is 0.620dl/g~0.685dl/g. The melt viscosity of the melt from the tempering and viscosity adjusting device is 0.620dl/g~0.685dl/g. The melt viscosity is 0.620dl/g~0.685dl/g, and the melt viscosity is 0.620dl/g~0.685dl/g. The melt viscosity is 0.620dl/g~0.685dl/g.

C: Preparation of a triethylene glycol diisooctanoate

2022051702 4Triethylene glycol diisooctanoate is a solvent-based cold plasticizer with excellent low-temperature properties, durability, oil resistance, UV irradiation resistance and antistatic properties, and low viscosity and certain lubricity. Its molecular structure can make plastic products with good color and transparency. Its similar polarity with resin makes it well soluble with resin, so it is widely used in many fields such as PVB safety film, synthetic rubber, vinyl resin, PVC, industrial coating and sealing material.
