1. Daim ntawv thov hauv kev tiv thaiv ib puag ncig
Nyob rau hauv kev tshawb fawb ntawm cov dej ib puag ncig pom tias pov tseg ib hnub twg, feem ntau muab faib ua nylon, polyethylene, polyester thiab lwm yam.Cov khib nyiab no tsis tuaj yeem degraded tag nrho nyob rau hauv ib puag ncig dej, thiab raws li tus nqi yuav loj thiab loj, lawv qhov kev puas tsuaj yog qhov tseeb.Yog tias siv cov ntaub ntawv degradation, lawv tuaj yeem degraded rau hauv cov tebchaw uas tsis muaj molecular nyob rau hauv qhov kev ua ntawm microbial secretory enzymes, thiab tom qab ntawd ua carbon dioxide thiab dej los ntawm microbial metabolism.
2. Cov thawv ntim khoom noj thiab kev lag luam ntim khoom siv
Biodegradable ntim cov ntaub ntawv feem ntau degradable polymers ntxiv rau laminate zaj duab xis los yog ncaj qha tov nrog cov khoom laminate los ua ib zaj duab xis.Hauv kev ntim khoom, kev tshawb fawb ntau dua yog siv cov hmoov txhuv nplej siab, cellulose, chitin thiab lwm yam khoom siv ntuj tsim nws tus kheej lossis hloov kho rau hauv cov thawv ntim khoom noj thiab ntim cov yeeb yaj kiab.British PORVAIR lub tuam txhab tsim polyurethane pob kws hmoov txhuv nplej siab cov khoom siv tshwj xeeb, degradation ceev, hmoov txhuv nplej siab ntxiv 50%, breathable thiab tuaj yeem tshuab rau hauv zaj duab xis, dav siv hauv ntim khoom noj.
3. Daim ntawv thov hauv kev ua liaj ua teb
Cov ntaub ntawv biodegradable feem ntau yog siv hauv kev ua liaj ua teb ua liaj ua teb mulch thiab ntim rau kev loj hlob qoob loo.Agricultural mulch tau dav tsim thiab siv hauv tsev thiab txawv teb chaws.Lub biodegradable concentrated master batch uas muaj N\P\K thiab lwm yam tshuaj tau npaj los ntawm Beijing Plastics Research Institute siv polyethylene ua cov khoom siv raw thiab ntxiv photocatalyst los ntawm degradation.Nws tau raug siv nyob rau hauv ntau hom kev ua liaj ua teb thiab ua tiav cov txiaj ntsig zoo.
4. Hauv daim ntawv thov kev kho mob
Thaum cov khoom ua tiav kev kho mob, nyob rau hauv ib lub sij hawm muaj peev xwm yuav hydrolyzed los yog enzymolysis rau hauv me me molecules los koom nyob rau hauv lub cev metabolic voj voog, thiaj li yuav absorbed los ntawm tib neeg lub cev.Cov ntaub ntawv biodegradable tau siv rau hauv kev phais vascular, phais orthopedic, hauv vivo tshuaj tso tawm matrix, nqus sutures thiab lwm yam kev kho mob.
