Munguva yakapfuura, iyo perfluorinated substance PFAS yakavharwa mukati memukati mevamwekurongedza chikafu vaive nehumwe carcinogenicity, saka vagadziri vazhinji vebepa chikafu chinokurumidza kurongedza vakashandura kupeta pamusoro pebepa nerunyoro rwePE, PP, EVA, sarin uye mamwe resin epurasitiki firimu kuti vazadzikise chinangwa chekusapinda mvura nemafuta, uye kudzivirira. kukuvadza kwezvinhu zvine perfluorinated kuhutano hwevanhu. Nekudaro, munzvimbo yechisikigo, sePFAS, chimiro chemolecular yemafirimu epurasitiki akagadzikana uye haagone kudzikiswa, nekudaro achikonzera kusvibiswa kwepurasitiki chena.
Naizvozvo, mamwe makambani akagadzira (anaerobic + marine) biodegradation tekinoroji yezvigadzirwa zvepolymer (senge mapurasitiki, rabha, kemikari fibers), iyo inogona kuwana ivhu biodegradation, marine biodegradation, uye compost degradation.
(Anaerobic + marine) biodegradation tekinoroji ndiyo yakaderera mutengo, iyo yekuwedzera mari ingori 1%, mutengo unongowedzerwa ne20% -30%, uye zvekutanga zvekugadzira zvinhu, zvigadzirwa zvekugadzira, maitiro, uye yakazara midziyo yezvinhu inoda kuchinjwa. Kusiyana neizvi, mutengo wehunyanzvi hwekuita biodegradable tekinoroji sePLA, PBAT, PBS, uye PHA ichawedzera nekanenge ka1-2, uye kuita kwese kwechigadzirwa chakapedzwa hakugone kusvika pakushanda kwemapurasitiki echinyakare. Mukuita kwekugadzira, zvigadzirwa, zvigadzirwa zvekugadzira, maitiro ekugadzira, nezvimwe zvinoda kushandurwa zvakanyanya uye kugadziridzwa.
Anaerobicbiodegradable masterbatch is organic masterbatch inogona kupinza mapurasitiki muchikamu che microbial degradation kuburikidza nemakemikari zviitiko zvinokonzerwa nebhakitiriya (kunyanya anaerobic bacteria), ichisiya chete carbon dioxide, methane uye humus, pakati peiyo methane inoshandiswa sesimba rakachena Rinodzokororwa, humus inogona kushandiswa se fetereza. Mushure mekuwedzera anaerobic biodegradable masterbatch kupurasitiki, inogona kuve yakasvibiswa mumarara kuburikidza neanaerobic reaction, uye inogona zvakare kuderedzwa mumvura yegungwa.
Anaerobic microbial degradation inoitika nguva dzese mumasikirwo, uye nekuti maitiro acho anononoka, hazvisi nyore kuona. Nekudaro, kuwedzera anaerobic biodegradable masterbatch kunogona kukurumidzira zvakanyanya kushatisa maitiro eakasimba organic mapurasitiki. Anaerobic biodegradable masterbatch inobvumira plastiki kuti ipedze matanho mana ekuderera pamwero wepamusoro.
Zvimiro uye zvakanakira zvakanakira (anaerobic + marine) biodegradation tekinoroji yebepa rakavharwa:
1. Yakachena uye yakachengeteka. Iyi tekinoroji inogona kushandiswa senge kabhoni sosi yeanaerobic microorganisms munzvimbo yeanaerobic, mushure mekuita enzymatic, kusvika iyo organic solid kabhoni sosi yagayiwa, inosangana zvizere neyakasvibira chigadzirwa zvinodiwa pakurongwa kwemarara.
2. Hapana chikonzero chekutsiva michina yekugadzira, hapana chikonzero chekuisa mari mune chero mitsva mitsva yekugadzira michina.
3. Haisi kukanganisa kushanda kwezvinhu zvepakutanga uye haiwedzere mari yakawanda.
4. Haisi kuganhurirwa nehupenyu hwesherufu yechigadzirwa uye nguva yekuchengetedza.
5. Rinogona kushandiswazve.
