- Kusafisha kwa Joto:<\/strong> <\/a>Kusafisha kwa joto kuna jukumu muhimu katika mchakato wa urejelezaji wa PET kwani unahusisha kusafisha vunjiko vya chupa kwa kutumia maji ya moto yenye joto zaidi ya 80\u00b0C. Njia hii huondoa kwa ufanisi mafuta, madoa, na vitu vingine vya kikaboni kutoka kwenye uso wa vunjiko vya chupa, kuathiri moja kwa moja usafi na ubora wa PET uliorejeshwa.<\/li>
- Utenganishaji wa Mzunguko:<\/strong> Utenganishaji wa mzunguko hutumia nguvu ya mzunguko inayozalishwa na mzunguko wa kasi kubwa ili kutenganisha nyenzo za uzito tofauti. Nyenzo zilizo na uzito mkubwa zaidi huenda nje kwa sababu ya nguvu ya mzunguko, wakati uchafu wenye uzito mdogo huendelea ndani au huondolewa. Njia hii mara nyingi hutumika kwa kutenganisha chembe ndogo ili kuhakikisha usafi wa bidhaa ya mwisho.<\/li>
- Njia ya Kupiga Mbizi:<\/a><\/strong> Njia ya kuondoa kwa kupiga mbizi huwatenganisha nyenzo na uchafu kulingana na tofauti za uzito wao. Katika maji au vyombo vingine, nyenzo zilizo na uzito mkubwa zaidi zitazama, wakati uchafu wenye uzito mdogo utapanda juu ya uso. Katika mchakato wa urejelezaji wa PET, utenganishaji wa uzito mara nyingi hutumika kuondoa uchafu wenye uzito mdogo, kama vile vifungashio, lebo, na nyenzo nyingine za plastiki, kutoka kwa vunjiko vya chupa za PET.<\/li> <\/ul>
