Kutengera kusiyana kwakukulu pakati pa njira yogwiritsira ntchito polyester yobwezeretsedwanso ndi polyester yachikale, zomwe zimapangitsa kuti pakhale makhalidwe osiyanasiyana, chitsanzocho chimakonzedwa motsatira mikhalidwe yomwe yatchulidwa ndikuyesedwa pa chromatograph yamadzimadzi yogwira ntchito bwino. Malinga ndi kusiyana kwa dera lapamwamba la chitsanzocho pansi pa nthawi zosiyanasiyana zosungira, kuti akwaniritse cholinga chozindikiritsa khalidwe.

1. Methanolysis

2. Kutupa-Kuchotsa

3. Kuzindikira kwa chromatography yamadzimadzi yogwira ntchito bwino kwambiri

Madzi oyeretsera omwe akonzedwa mu 1 ndi 2 pamwambapa amayesedwa kuti aone ngati ali ndi mphamvu zambiri.

4. Kukonza ndi kuzindikira deta

Polyester yobwezeretsedwanso idzasintha zomwe zili mkati ndi kufalikira kwa ma macromolecular heterogeneous chain links ndi oligomers panthawi yokonzekera, zomwe zingagwiritsidwe ntchito ngati maziko ozindikiritsa polyester yobwezeretsedwanso ndi polyester ya virgin.

Chidziwitso chenicheni cha malo otsetsereka ndi kuchuluka kwa malo otsetsereka chikuwonetsedwa mu tebulo ili m'munsimu.

Chifukwa cha kuchuluka kwa anthu omwe amagwiritsa ntchito polyester komanso kuzindikira kwawo za kuteteza chilengedwe, chidwi chachikulu chikuperekedwa pakugwiritsanso ntchito zinyalala za polyester. Kugwiritsa ntchito zinyalala za polyester popanga ulusi wa polyester wobwezeretsedwanso kungachepetse ndalama, kuchepetsa kugwiritsa ntchito mafuta, komanso kupititsa patsogolo phindu lazachuma, zomwe ndizofunikira kwambiri pakukula kokhazikika kwa makampani opanga ulusi wa mankhwala.
Nthawi yomweyo, chifukwa cha kuchuluka kwa polyester yobwezeretsedwanso, nkhani yosintha polyester yobwezeretsedwanso ndi polyester yoyambirira yakopa chidwi chachikulu kuchokera ku makampani opanga zinthu. Mitengo ya zinthu ziwirizi ikuwonetsanso mgwirizano wabwino, ndipo kuzindikira kusiyana pakati pa zinthu ziwirizi kukuchulukirachulukira.
