PBS yog cov khoom siv biodegradable yas uas muaj ntau yam kev siv, uas tuaj yeem siv rau hauv ntim, cov tais diav, lub fwj tshuaj pleev ib ce thiab tshuaj fwj, cov khoom siv kho mob pov tseg, cov yeeb yaj kiab ua liaj ua teb, tshuaj tua kab thiab cov chiv, cov ntaub ntawv tso tawm qeeb, biomedical polymers thiab lwm yam. .
PBS muaj kev ua tau zoo tshaj plaws, tsim nyog tus nqi ua haujlwm thiab kev cia siab rau daim ntawv thov. Piv nrog rau lwm yam biodegradable plastics, PBS muaj cov khoom siv zoo heev, ze rau PP thiab ABS yas; Nws muaj cov cua kub zoo, nrog rau qhov kub thiab txias distortion ze li ntawm 100 ℃, thiab hloov kho qhov kub ntawm ze li 100 ℃, uas tuaj yeem siv rau kev npaj cov pob khoom kub thiab txias thiab cov thawv noj su, thiab kov yeej cov kev tsis txaus ntawm lwm cov khoom siv biodegradable. nyob rau hauv cov nqe lus ntawm tsawg tshav kub kuj kub;
PBS kev ua tau zoo heev, tuaj yeem ua tau nyob rau hauv cov khoom siv dav dav siv rau txhua yam kev ua molding, PBS yog tam sim no qhov zoo tshaj plaws degradation ntawm plastics processing kev ua tau zoo, tib lub sij hawm tuaj yeem ua ke nrog ntau cov calcium carbonate. , hmoov txhuv nplej siab thiab lwm cov khoom ntim, kom tau txais cov khoom lag luam qis; PBS ntau lawm tuaj yeem ua tiav los ntawm kev hloov pauv me ntsis ntawm cov khoom siv dav dav ntawm cov khoom siv polyester uas twb muaj lawm, cov khoom siv polyester hauv tsev tam sim no tsim muaj peev xwm ntawm qhov loj tshaj, kev hloov pauv ntawm cov khoom siv PBS rau cov khoom siv polyester zoo tshaj plaws muab lub sijhawm zoo rau production PBS. Tam sim no, cov khoom siv polyester hauv tsev yog overcapacity tiag tiag, kev hloov pauv ntawm PBS ntau lawm rau cov khoom siv polyester ntau dua muab kev siv tshiab. Tsis tas li ntawd, PBS tsuas yog degraded nyob rau hauv tej yam kev mob microbiological xws li composting thiab dej, thiab nws cov kev ua tau zoo heev ruaj khov thaum lub sij hawm cia thiab siv.
PBS, nrog aliphatic dibasic acid thiab diols ua cov ntaub ntawv tseem ceeb, tuaj yeem ua tau raws li qhov xav tau nrog kev pab ntawm petrochemicals los yog tsim los ntawm bio-fermentation txoj hauv kev los ntawm cellulose, cov khoom noj los ntawm cov khoom noj, qabzib, fructose, lactose thiab lwm yam kev tsim dua tshiab. qoob loo cov khoom, yog li realizing lub ntsuab recycling ntau lawm ntawm xwm thiab rov qab mus rau xwm. Ntxiv mus, cov khoom siv raw uas tsim los ntawm cov txheej txheem bio-fermentation tuaj yeem txo tus nqi ntawm cov khoom siv raw, yog li txo tus nqi ntawm PBS.
