1. Kushandisa mumunda wekuchengetedzwa kwezvakatipoteredza
Pakuferefetwa kwenzvimbo yemvura yakawana kuti tsvina zuva nezuva, kazhinji yakakamurwa kuita naironi, polyethylene, polyester uye zvichingodaro.Iyi tsvina haigoni kuderedzwa zvachose munzvimbo yemvura, uye sezvo mari yacho inova yakakura uye yakakura, kukuvadza kwavo kunozviratidza.Kana midziyo yekushatisa ikashandiswa, inogona kuderedzwa kuita yakaderera mamorekuru makomisheni pasi pechiito che microbial secretory enzymes, uye wobva waita kabhoni dhaimoni nemvura kuburikidza nehutachiona hwemetabolism.
2. Chikafu chigadziko uye kurongedza indasitiri zvikumbiro
Biodegradable packaging zvinhu zvinowanzo shatisa mapolymer anowedzerwa kune laminate firimu kana kusanganiswa zvakananga nelaminate zvinhu kugadzira firimu.Mumidziyo yekurongedza, kutsvagisa kwakawanda ndiko kushandiswa kwestarch, cellulose, chitin uye zvimwe zvechisikigo zvepolymer zvinhu pachazvo kana kuchinjirwa mumidziyo yechikafu nemafirimu ekurongedza.Kambani yeBritish PORVAIR yakagadzira polyurethane chibage starch epurasitiki zvimiro zvezvinhu zvakakosha, kukurumidza kukanganisa, starch yakawedzera huwandu hwe50%, inofema uye inogona kupeperetswa kuita firimu, rinoshandiswa zvakanyanya mukurongedza chikafu.
3. Kushandisa mune zvekurima
Biodegradable zvinhu zvinonyanya kushandiswa mukurima semurimi mulch uye midziyo yekukura kwembesa.Agricultural mulch yakagadziridzwa zvakanyanya uye inoshandiswa kumba nekune dzimwe nyika.Iyo biodegradable concentrated master batch ine N\P\K uye zvimwe zvinhu zvemakemikari yakagadziriswa neBeijing Plastics Research Institute ichishandisa polyethylene seyakanyanya mbishi zvinhu uye kuwedzera photocatalyst nekuora.Yakashandiswa munzvimbo dzakasiyana-siyana dzekurima uye yakawana migumisiro yakanaka.
4. Mukushandiswa kwezvokurapa
Kana izvo zvinhu zvapedza basa rekurapa, mune imwe nguva inogona kuve hydrolyzed kana enzymolysis kuita mamorekuru madiki kutora chikamu mune yakajairika metabolic kutenderera, kuitira kuti inyudzwe kana kuburitswa nemuviri wemunhu.Biodegradable zvinhu zvakashandiswa mukuvhiya vascular, orthopedic kuvhiyiwa, in vivo drug release matrix, absorbent sutures nedzimwe nzvimbo dzekurapa.
