Perent Polymers - Polymers iyo Balance Zvivakwa zvemuviri uye Zvemamiriro ekunze - Hauna kuvapo, asi Polybutylene Terephthalate (PST) iri pedyo nekukwana kupfuura mazhinji.
Mushure memakumi emakore ekutadza kumisa zvigadzirwa zvavo zvinopera mumanyorero nemakungwa, vagadziri vechiSynthetic, vagadziri vekumanikidza vari pasi pekumanikidzwa kutora mutoro. Vazhinji vari kuendesa kuedza kwavo kusimudzira kudzokorodza kuti varege kutsoropodzwa. Mamwe makambani ari kuyedza kugadzirisa dambudziko rekurara nekudyara muBiodegradable Bio-Plastics akadai saPolylacticic acid (Playhydroxy Fatty Acters
Asi zvese zviri zviviri uye biopoplymers inotarisana nezvipingamupinyi. Semuenzaniso, kunyangwe makore ekuedza, United States ichiri kudzokorora zvisingasviki gumi muzana yemapurasitiki. Uye bio-based polymers - kazhinji zvigadzirwa zvekufemerwa - vari kunetseka kuzadzisa kuita uye chiyero chevaridzi vechiSynthetic vanoitirwa kutsiva.
PBAT inosanganisa zvimwe zvezvinhu zvinobatsira zvevakareva uye bio-based polymers. Iyo inotorwa kubva kune yakajairika petrochemical zvigadzirwa - yakanatswa terephthaal acid (pta), butanediol uye adipic acid, asi iri bioderable. Semanyama anogadzira, inogona kuve yakagadzirwa zvakanyanya-kugadzirwa, uye ine zvivakwa zvemuviri zvaidikanwa kuti zviite mafirimu anochinjika akafanana neaya enyama dzechinyakare.
Kufarira pabhat kuri kuwedzera. Vanogadzira zvigadzirwa zvakaita seGermany Basf neChigamo's Laars vari kuona zvakawedzera kudiwa mushure memakore ekurera musika. Vakabatanidzwa nehafu kupfuura gumi nemaviri vaAsia vafambi vanotarisira bhizinesi rePolymer kuti vawedzere kuhurumende dzedunhu vanosundira pakuraramisa.
Marc Verbruggent PBS) uye pha inokwikwidza. Uye ingangodaro yekukwira padivi paPlises maviri akakosha biodegradable mapurasitiki, ayo anoti ari kuita chigadzirwa chakakura chechigadzirwa chekuomarara.
Ramane narayan, purofesa wemakemikari engineering University Zvisungo zvesimba zviri nyore hydrolyzed uye zvakakuvadzwa nema enzymes.
Semuenzaniso, polylactic acid uye pha ndeye polysters inosvibisa kana yavo ester zvisungo zveshuwa zvinotyora. Asi iyo inonyanya kujairika polyester - polyethylene terephthalate (pet), inoshandiswa mumachira uye soda mabhodhoro - haatyisi zviri nyore. Izvi zvinodaro nekuti chinonhuwira chinonhuwira mumhino yayo kubva paPTA. Sekureva kwaNarah, zvindori zvinopa zvimiro zvemhando zvakare zvinoita kuti pet hydrophobic. "Mvura haisi nyore kupinda uye inoderedza mamiriro ese eHydrolysis," akadaro.
Basf inoita polyutyley terephthalate (PBT), polyester yakagadzirwa kubva kuButanedol. Vatsvagiri vekambani vakatsvaga polymeri bolommeri vanogona kugadzira nyore nyore. Ivo vakatsiva imwe PTA muPBT neAditi Dicid glycolic acid. Nenzira iyi, zvinetso zvekunhuhwirira kwemapolymeri zvakaparadzaniswa kuitira kuti vave bioderable. Panguva imwecheteyo, yakakwana pta inosara kuti ipe iyo polymer yakakosha zvivakwa zvemuviri.
Narayan anotenda phat iri zvishoma bioderdable kupfuura pla, inoda maindasitiri compost yekuora. Asi haigoni kukwikwidza neyekutengeswa maPhiya, ayo ari biozozandable mumamiriro ezvinhu echisikigo, kunyangwe munzvimbo yemaraki.
Nyanzvi dzinowanzoenzanisa zvivakwa zvepanyama zvePbat kuderera-density polyethylene, polymer yakashandiswa kuita mafirimu, senge marara emarara.
PBAT inowanzo kusanganiswa ne pla, polymer ine polystyrene-kunge zvivakwa. Basf's Ecario Brand yakavakirwa pachibatanidza ichi. Semuenzaniso, verbrugggen vanoti bhegi rekutenga rinotenga kazhinji rine 85% PHAT uye 15% Pla.
Novamont inowedzera imwe danho kune iyo nzira yekubheka. Iyo kambani inosanganisa PHBA uye imwe biodegradable aliphatic polysters ine starch yekugadzira resins kune zvakanyatso.
Stefano Facco, Iyo New New Bhizinesi Development Manager, akati: "Kwemakore makumi matatu apfuura, Makore makumi matatu apfuura "
Musika mukuru wePBhat ari mulch, iro rinopararira zvirimwa zvekudzivirira masora uye kubatsira kuchengetedza kunyorova. Kana polyethyle firimu rinoshandiswa, rinofanira kudhonzwa uye rinowanzovigwa mumarara. Asi mafirimu epaliodems anogona kuvandudzwa zvakananga muvhu.
Imwewo misika mikuru ndeyemaruva marara emarara ebasa rekudya uye imba yekuunganidza chikafu neyadhi.
Mabhegi kubva kumakambani akadai saBiobag, achangobva kuwanikwa naLovamont, akatengeswa kune vatengesi kwemakore.
