Denetlenen Tedarikçi Raw material: Resin or recycled PET, PA6, PA66, PTT
The solid state viscosity increasing device consists of: drum reactor, thermal oil heating and cooling system, vacuum system, electrical PLC (or DCS) control, etc.
And optional: automatic feeding and conveying, pre-crystallization system, automatic discharging and conveying, raw material dust removal and screening, nitrogen protection, etc.
The increase in IV(Intrinsic Viscosity) is based on the molecular characteristics of the copolymer. At the critical temperature, thanks to the special extreme vacuum technology and high-precision temperature control, small molecular weight chemicals will be extracted along with the vacuum pipeline and the copolymer molecular chain will be extended so that In order to meet the requirements of increasing viscosity, IV(Intrinsic Viscosity) can be steadily increased and high-purity and high-viscosity PET can be obtained, which can be used in spinning, industrial yarn, POY, FDY, packaging sheet, preform production and bottle-to-bottle recycling.
Machine model: From 5 L to 46 cubes, Customized according to production capacity
Out-put capacity: From 1Kg/ batch to 23000kg/ batch
One batch time: 26 hours to 36 hours (Depends on target IV and original IV)
