Ndi kupita patsogolo kosalekeza kwaukadaulo wopanga nsalu, ulusi watsopano wochulukirachulukira wasanduka zida zopangira nsalu. Lero, ndikudziwitsani zaukadaulo wozindikiritsa ulusi wopangidwanso wa polyester.
Zikumveka kuti m'mbuyomu, chifukwa cha kusowa kwa njira zoyendera komanso kulephera kwa mabungwe oyesera kupereka malipoti oyenerera, mabizinesi sakanatha kusangalala ndi mfundo zadziko zoyenera, ndipo nthawi yomweyo zidayambitsa chisokonezo pakulemba zinthu zina za polyester.
Kodi fiber recycled polyester (PET) ndi chiyani?
Ndiko kuti, zotayidwa za polyester (PET) polima ndi zinyalala za polyester (PET) zopangira nsalu zimasinthidwanso ndikusinthidwa kukhala ulusi wa polyethylene terephthalate.
M'mawu a anthu wamba, ulusi wa poliyesitala wobwezerezedwanso (omwe tsopano umatchedwa poliyesitala wobwezerezedwanso) amatanthauza poliyesitala yobwezerezedwanso (monga ma flakes a mabotolo, thovu, silika, zinyalala, nsalu zotayidwa, ndi zina zotero) zopangidwa ndi njira zobwezeretsanso. Ester fiber.
Mfundo Yodziwika
Kutengera kusiyana kofunikira pakati pa njira yopangira zobwezerezedwanso poliyesitala ndi namwali poliyesitala, zomwe zimabweretsa mikhalidwe yosiyana, chitsanzocho chimakonzedwa molingana ndi zomwe zatchulidwa ndikuyesedwa pa chromatograph yamadzi ambiri. Malinga ndi kusiyana pachibale pachimake m'dera la chitsanzo pansi osiyana posungira nthawi , Kukwaniritsa cholinga chizindikiritso Mkhalidwe.
Gawo lachizindikiritso
1. Methanolysis
2. Kutupa-Kuchotsa
3. High ntchito madzi chromatography kuzindikira
Zakumwa zochizira zomwe zakonzedwa pamwambazi 1 ndi 2 motsatana zimayang'aniridwa ndi chromatography yamadzimadzi kwambiri.
4. Kukonza deta ndi kuzindikira
Zobwezerezedwanso poliyesitala zidzachititsa kusintha zili ndi kugawa macromolecular heterogeneous unyolo maulalo ndi oligomers pa ndondomeko kukonzekera, amene angagwiritsidwe ntchito ngati maziko a chizindikiritso cha zobwezerezedwanso poliyesitala ndi namwali poliyesitala.
Chisomo cha malo enieni komanso chidziwitso chazomwe zili m'munsimu.

Yang'anani m'tsogolo
Ndi kuchuluka kwa kugwiritsidwa ntchito kwa poliyesitala komanso kuzindikira kwa anthu zachitetezo cha chilengedwe, chidwi chochulukirapo chimaperekedwa pakukonzanso zinyalala za polyester. Kugwiritsa ntchito zinyalala za polyester kupanga ulusi wobwezerezedwanso wa poliyesitala kumatha kuchepetsa mtengo, kuchepetsa kugwiritsa ntchito mafuta, komanso kupititsa patsogolo phindu lazachuma, zomwe ndizofunikira kwambiri pakukula kosatha kwamakampani opanga mankhwala.
Pa nthawi yomweyo, ndi kuwonjezeka kuchuluka kwa poliyesitala zobwezerezedwanso, nkhani ya m'malo mwa poliyesitala zobwezerezedwanso ndi namwali poliyesitala wakopa chidwi kwambiri makampani. Mitengo yamtengo wa awiriwa ikuwonetsanso mgwirizano wina wabwino, ndipo kuzindikira kusiyana pakati pa zamakono zamakono kukupeza chidwi kwambiri.
