Kugwiritsa ntchito pulasitiki zochokera ku petroleum kumatsutsidwa chifukwa cha zinthu zodziwika bwino za kuwonongeka kwa oyera. Kufunafunanso mabotolo okhazikika ngati njira inayake kwakhala kofunika kwambiri komanso mwachangu. Polylactic acid (pl) amadziwika kuti ndi ena omwe angakhalepo m'malo mwazinthu wamba zochokera ku petroleum. Monga momwe zinthu zosinthira zimachokera ku biolucass yovomerezeka, zinthu zabwino, komanso kuwonongeka kwa msika wowuma mu mapulagisi, zida zam'matawuni, zopangidwa ndi mafakitale ogwiritsa ntchito mafakitale. Komabe, kutentha kwake kochepa komanso kulimba pang'ono kumachepetsa ntchito zosiyanasiyana.
Kuphatikizika kwa polylactic acid (plu) ndi thermoplastic siconen polyurethane (TPIUU) Elastomer adachitidwa.
Zotsatira zake zinawonetsa kuti TPIUU inali bwino kwambiri mu pla, koma palibe mankhwala omwe amachitika. Kuphatikiza kwa tsiyiu kunalibe zotsatira za kutentha kwagalasi ndikusungunuka kutentha kwa pla, koma pang'ono kuchepetsedwa malemu a plapleyi.
Ma morphology ndi mphamvu yowunikira yowunikira kuwonetsa kuphatikizidwa kwa thermodynamic pakati pa pla ndi tpsiu.
Maphunziro a RHHOOGOLACE Mkhalidwe adawonetsa kuti Pla / TPIU imasungunuka inali preeudoplactic madzimadzi. Monga zomwe zili ku TPIU zimanjenjemera, kuwoneka ngati mafayilo a plab / tpsiu kumawonetsa kukweza koyamba kenako ndikugwa. Kuphatikiza kwa Tykiu kunali ndi mphamvu kwambiri pa makina opanga a pla / tpsiu kuphatikiza. Mukakhala kuti TPIUU idalipo 15 wt%, malo okwirira ku Ruble Plassion 22.3% (ma 5.0) kutanthauza kukoma kosangalatsa.
Poyerekeza ndi TPU, TPIU ili ndi vuto lalikulu pagombe mbali imodzi komanso kukana kutentha kwabwino mbali inayo.
Komabe,Siltike Si-TPVndi mphamvu yovomerezeka ya Thermoplain-elastone yochokera ku Slasmone. Ikujambula nkhawa zambiri chifukwa chokhala ndi khungu lopanda khungu komanso lapadera, kukana kwabwino, kukana kupusa ndi mafuta onunkhira, palibe kutulutsa magazi / zopanda pake.
Komanso, zosokoneza bwino pa pla.
Zinthu zotetezekazi ndi zachilengedwe, zimapereka kuphatikiza kwa katundu ndi mapindu kuchokera pa a thermoplastics ndi mphira wolumikizidwa ndi silika yolumikizidwa ndi silikane. Ma suti owoneka bwino, pulasitiki yazithunzi, zinthu zopanda pake, zopangidwa, ntchito zamafashoni.
Pamwambazi, zochokera ku polima (Basel). 2021 Jun; 13 (12): 1953. ndipo, Super Moly Wovuta (Lactic acid) amaphatikizananso kwambiri "(RSC Act.
