Naizvozvo, makambani eChinese akagadzira uye kugadzira tekinoroji-okisijeni biodegradation tekinoroji yezvigadzirwa zvepolymer (senge mapurasitiki, rabha, uye makemikari fibers), ayo anogona kuwana marara biodegradation uye compost degradation.

Photo-oxygen biodegradable masterbatch ndiyo yepedyo biodegradation tekinoroji kusvika kushatisa nekukurumidza munzvimbo yechisikigo.Kuwedzerwa kwe1% kunogona kukurumidza kuparara pasina kuchinja zvinhu, zvigadzirwa zvekugadzira, maitiro ekugadzira uye kuita kwese kwechinyorwa.

Nekudaro, mutengo weiyo yechinyakare polylactic acid PLA, PBAT, PBS, PHA uye humwe hutekinoroji hwakakwana hunowedzera ne100% kusvika 200%, uye kuita kwakazara hakugone kusvika pakuita kwemapurasitiki echinyakare, saka zviwanikwa, zvigadzirwa zvekugadzira uye maitiro ekugadzira. inoda kuchinjwa.

Iyo foto-okisijeni biodegradation tekinoroji yemafirimu epurasitiki senge PE uye sarin inogona kushandiswa mukugadzira mapepa akavharidzirwa nekukurumidza chikafu pamusika mumusika weChina.#PE yakavharwa bepa roll

Tekinoroji musimboti wepikicha-okisijeni biodegradation tekinoroji

Iyo kambani yeChinese firimu repurasitiki refoto-oxidative biodegradation tekinoroji imhando yehunyanzvi hwekuvandudza iyo biodegrades zvachose zvichienderana nefirimu repurasitiki rakaraswa munzvimbo yechisikigo.Iyo tekinoroji yakagadzirirwa kuchengetedza hupenyu hwayo hunobatsira sechinhu uye michina yayo, mechanika, chipinganidzo, pachena uye zvimwe zvekutengesa zvinhu mukati mehupenyu hwayo hwese, uye inobvumira mafirimu epurasitiki ku biodegrade pasi pemamiriro echisikigo mushure mekuraswa.

Iyo tekinoroji ndeyekuwedzera mufananidzo-okisijeni biodegradable masterbatch kufirimu repurasitiki kuti riite semufananidzo-okisijeni biodegradable epurasitiki olefin firimu.Kuvandudza kumhanya kunopinzwa maatomu eokisijeni mumaketani epolymer emapolymer epurasitiki.Iwo epurasitiki ma polymers akaputswa kuita madiki mamorekuru zvinhu munzvimbo ine aerobic, uye obva aora ne microorganisms ubiquitous munzvimbo yechisikigo.#PE yakavharwa bepa rezasi roll

Maitiro ekushatisa emafirimu epurasitiki achishandisa mufananidzo-okisijeni biodegradation tekinoroji inogona kukamurwa kuita nhanho mbiri.
Danho rekutanga: Iyo firimu repurasitiki rakawedzerwa neiyo photo-oxygen biodegradable masterbatch inopindirana neokisijeni mumhepo, zvichiita kuti chiwedzere kurwisa kabhoni cheni yepolymer, uye kabhoni musana unoiswa oxidized kuumba zvimedu zvemamolecular zvine hushamwari hwema molecular mass. isingasviki 10,000 kana zvishoma ( Masayendisiti muEurope neJapan anotenda kuti oligomers ane hukama hwema molecular mashoma pasi pe400,000 anogona kumedzwa ne microorganisms).

Muchikamu chino, kushatisa iabiotic process, inosimudzira kuiswa kwemaatomu eokisijeni mumusana wecarbon apo polima inotsemuka kuita mapoka akasiyana anoshanda (senge carboxylic acids, esters, aldehydes, uye madoro).

Iyo yakakwira molecular polymer inoshanduka kubva kune hydrophobic macromolecule cheni kuenda kune hydrophilic diki molecular cheni, iyo inoita kuti zvimedu zvemolecular cheni zvive nyore kukukurwa uye kugaya nemabhakitiriya.# Raw material bepa cup fan

Danho rechipiri: ma microorganisms anowanikwa kwose kwose (mabhakitiriya, fungi uye algae) mumasikirwo anoodza firimu repurasitiki sechinhu chinovaka muviri, uye rinopedzisira raora kuita carbon dioxide, mvura uye biomass.Kudzikira padanho iri kunonzi biodegradation process.

Ingave mumhepo yakavhurika kana murabhoritari, chiyero chekuora chehunyanzvi uhu hunogona kusvika kupfuura 60%.Munyika yangu yenyika zviyero GB/T 20197-2006 uye GB/T 19277.1-2011, iyo yepamusoro-soro yekuyedzwa kweiyo biodegradation rate i60%.

Munzvimbo yerabhoritari, kumafirimu ane hukobvu husingasviki 15 μm, vanogona kupinda muchikamu che biodegradation mushure mekuenzanisa mwedzi mitatu yekuchembera kwepanyama.Simulated kuchembera anogona kusarudza UV kuchembera kana xenon rambi kuchembera.

Kupinda munhanho ye biodegradation, iyo yepamusoro-soro yepololefin yekudzikisira mwero munyika (PAS 9017: 2020) inoda mwero wekuderedzwa unodarika makumi mapfumbamwe muzana mukati memazuva mazana manomwe nemakumi matatu, uyo wakakwira zvakanyanya kupfuura mwero wenyika munyika yangu.

Iyo tekinoroji mwero weiyo photo-oxidative biodegradation tekinoroji yepurasitiki firimu inodarika mwero yenyika, inofambirana neyakaomesesa polyolefin degradation standard munyika (PAS 9017: 2020).

Mushure mekusanganisa iyo pikicha-okisijeni biodegradable masterbatch mumapurasitiki emarara sePE nesarin, zvigadzirwa zvinogadzirwa zvine biodegradable zvimiro, uye yavo yemazuva-180 biodegradation rate inogona kusvika makumi matanhatu muzana, ichisangana nenyika standard GB/T 38082- 2019 inodiwa biodegradation rate.Inogona kuve yakazara biodegraded pasi pemamiriro ekuvhurika mhepo yekurasa, ivhu kana aerobic composting.# PE yakavharwa bepa pepa

Photo-oxygen biodegradation tekinoroji inogona kupasa kuyedzwa kweanotevera Chinese nyika mwero: GB/T 20197-2006, GB/T 19277.1-2011, GB/T 38082-2019.Zvinoenderana neyazvino mbiri kabhoni mutemo uye huzivi.
