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 Sheet extrusion, 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: Re tlo sebelisa lisebelisoa tse ncha empa ha re na boiphihlelo ba ho omisa lintho tse joalo. O ka re thusa?
A: Feme ea rona e na le Setsi sa Teko. Setsing sa rona sa Teko, re ka etsa liteko tse tsoelang pele kapa tse sa khaotseng bakeng sa lisebelisoa tsa sampole tsa moreki. Thepa ea rona e na le theknoloji e felletseng ea automation le methalo.
Re ka bonts'a --- Ho fetisa / Ho Laola, Ho Omisa & Crystallization, Ho lahla.
Ho omisa le kristallise ea lintho tse bonahalang ho fumana mongobo o setseng, nako ea bolulo, ho kenya matla le thepa ea thepa.
Hape re ka bonts'a ts'ebetso ka ho fana ka likonteraka tse nyane bakeng sa lihlopha tse nyane.
Ho latela litlhoko tsa hau tsa thepa le tlhahiso, re ka etsa 'mapa oa moralo le uena.
Moenjiniere ea nang le boiphihlelo o tla etsa tlhahlobo. Basebetsi ba hau ba memeloa ka mofuthu ho nka karolo litseleng tsa rona tse kopaneng. Kahoo u na le monyetla oa ho kenya letsoho ka mafolofolo le monyetla oa ho bona lihlahisoa tsa rona li sebetsa.
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.
