Tlhaloso e Khutšoanyane:

Tharollo bakeng sa mohala oa granulating oa rPET Extrusion ( Viscosity degration e ka bang 0.028)

Ho omisa le ho kristale ha rPET Bottle Flake ka mohato o le mong ho ≤30ppm ka 20mins

Ho qala hang-hang le ho koala kapele, ha ho hlokahale ho omisa esale pele

Melt strips ha e fetohe mosehla hobane nako ea ho omisa e fokotsehile

 

 

 


  • Ho omisa & Crystallization : Ka mohato o le mong
  • Mongobo oa ho qetela : ≤30ppm
  • Theko ea matla: 0.06-0.08kwh/kg
  • Nako ea ho omisa : 20metsotso
  • Ho eketseha ha sekhahla sa letlapa: 15-20%
  • Ho senyeha ha viscosity ka mor'a extrusion: hoo e ka bang 0.028

P: Mongobo oa ho qetela oo u ka o fumanang ke ofe? A na u na le meeli ho mongobo oa pele oa thepa e tala?

A: Mongobo oa ho qetela oo re ka o fumanang ≤30ppm (Nka PET e le mohlala). Mongobo oa pele o ka ba 6000-15000ppm.

 

P: Re sebelisa Double parallel screw extruding le vacuum degassing system bakeng sa PET Extrusion granulating line, na re ntse re hloka ho sebelisa pre-dryer?

A: Re fana ka maikutlo a ho sebelisa Pre-dryer pele ho extrusion. Hangata sistimi e joalo e na le tlhoko e tiileng ea mongobo oa pele oa lisebelisoa tsa PET. Joalo ka ha re tseba PET ke mofuta oa thepa e ka monyang mongobo o tsoang sepakapakeng e tla etsa hore mohala oa extrusion o sebetse hampe. Kahoo re fana ka maikutlo a ho sebelisa pre-dryer pele ho sistimi ea hau ea extrusion:

>> E fokotsa ho senyeha ha hydrolytic ea viscosity

>>Thibela ho eketseha ha maemo a AA bakeng sa lisebelisoa tse amanang le lijo

>> Ho eketsa bokhoni ba mohala oa tlhahiso ho fihla ho 50%

>> Ntlafatso le ho etsa hore boleng ba sehlahisoa bo tsitsitse-- Mongobo o lekanang le o phetoang oa thepa

 

P: Nako ea ho fana ka Ird ea hau ke mang?

A: Matsatsi a 40 a ho sebetsa ho tloha ha re fumana depositi ea hau akhaonteng ea rona ea k'hamphani.

 

P: Ho thoe'ng ka ho kenya IRD ea hau?

Moenjineri ea nang le boiphihlelo a ka u thusa ho kenya sistimi ea IRD bakeng sa hau fekthering ea hau. Kapa re ka fana ka litšebeletso tsa tataiso inthaneteng. Mochini oohle o sebelisa plug ea sefofane, e bonolo bakeng sa khokahano.

 

P: IRD e ka sebelisoa bakeng sa eng?

A: E ka ba pre-dryer bakeng sa
