Iko kushandiswa kwemapurasiteti echiSynthetic kunobva kune petroleum kunonaka nekuda kwenyaya dzakanyatsozivikanwa dzechena kusvibiswa kwenhema. Kutsvaga nzvimbo dzekuvandudza kabhoni seimwe nzira yave yakakosha uye yekukurumidzira. Polylactic acid (Pla) yakafungidzirwa zvakanyanya ingano ingano yekutsiva zvakajairika petroleum-based zvigadzirwa. Sekushandiswa kwekuvandudzwa kunobva kune biomass ine michero yekukwira, uye kusvibiswa, Pla yakawana kuputika kwemusika mapurasitiki emapurasitiki Nekudaro, iyo yakaderera kupisa kupokana uye yakaderera kutama kudzikamisa kwakanyanya huwandu hwayo hwekushandisa.

Iyo nyungudutswa kusanganisa yePolylactic acid (Pla) uye Thipmoplastic Silitone polyurethane (TPSIU) Elasomer yakaitwa kuToughen Pla.

Mhedzisiro yacho yakaratidza kuti TPSIU yakave yakabatanidzwa zvakanyatsobatanidzwa muPla, asi hapana maitiro emakemikari akaitika. Kuwedzerwa kweTPSIU hakuna kujeka pane iyo girazi tembiricha tembiricha uye yekunyungudika tembiricha yePla, asi yakaderedzwa zvishoma crystallinity yePla.

Iyo morphology uye dynamic mechanical quanis mhedzisiro yakaratidza iyo isina murombo Thermodynamic kuwirirana pakati pokutanga pakati pePla uye tpsiu.

Rheological Deal fundo yakaratidza kuti Pla / TPSIU YELT YAKAITWA PSEUDOPLAPLATIST FLUID. Sezvo zviri mukati meTPSIU chakawedzera, iyo jekuvesa ratidziro yePla / TPSIU Blends yakaratidza maitiro ekusimuka kwekutanga uye obva adonha. Kuwedzerwa kweTPSIU kwakave nemhedzisiro yakakosha pazvinhu zvekushandisa zvePla / tpsiu. Kana zvirimo zveTpsiu zvaive gumi neshanu Kupa zano rekushomeka kwekushongedza.

Kuenzaniswa neTPU, TPSIU ine maitiro ari nani ekushongedza pane pla pane rimwe ruoko uye riri nani kupisa kupesana nerumwe ruoko.

Nekudaro,Silike Si-TPVIs denderedzwa rakazara vulcanized thermoplastic silicone-basks elastomers. Iyo yakakwevera kunetseka kwakawanda nekuda kweiyo nzvimbo yayo yakasarudzika uye yeganda-inoshamwaridzana yekubatira, isiri nani kupokana, isina mafuta ekunyepedzera, hapana njodzi / inonamira njodzi, hapana kunhuhwirira.

Uyezve, zvirinani kusimbisa maitiro paPla.

Iyi yakasarudzika yakachena uye ine hushamwari-inoshamwaridzana, inopa musanganiswa wakanaka wezvivakwa uye zvinobatsira kubva kuTernmoplastics uye kuyambuka zvizere-zvakabatanidzwa silicone rubber. Suits ye inorerally pamusoro, engineering plastics, biomeical zvinhu, machira, maindasitiri ekuputika mafirita.

Pamusoro peruzivo, yakajeka kubva phermers (basel). 2021 Jun; 13 (12): 1953. uye, Super yakaoma Poly (LATTCI ACID) YEMAHARA YEMAHARA "(RSC Adv., 2020,10,13316-13368)
