Hamwe n’umwanda w’umwanda “umwanda wera”, ibihugu byo ku isi byatangije itegeko rikaze rya plastike, rishobora kubora imifuka ya pulasitike kugira ngo ifate amaduka manini n’ibigo by’ubucuruzi.Urebye neza uzasanga iyi mifuka ya pulasitike yangirika hafi ya yose ari hafi yubwoko bwose.Pbat + PLA + ST.None ni izihe nyungu za PBAT + PLA + ST?
Imwe: ibinyamisogwe
Ibinyamisogwe bikwirakwizwa cyane mu mbuto cyangwa imbuto z'ibiti, imizi cyangwa amababi.Hano hari toni zigera kuri miriyoni amagana yumusaruro wa krahisi buri mwaka.Nimwe mubintu byinshi bishobora kuvugururwa kandi bigashobora kwangirika.Ifite ibyiza byamasoko yagutse nibiciro biri hasi.Nyamara, kubera ko ibinyamisogwe bisanzwe bifite imiterere ya microcrystalline nuburyo bwa granulaire, ntabwo ifite imikorere yo gutunganya thermoplastique, kandi igomba guhinduka muburyo bwa armoplastique kugirango ibashe gukora thermoplastique.
Babiri: PBAT
Acide Polycolike / fenyl -dysic aside dysol (PBAT) ni ubwoko bwa polyester yangirika yakwegereye abantu benshi.Kandi guhindagurika birashobora kandi kugabanuka kumazi na karuboni ya dioxyde de carbone mubihe bisanzwe.
Nyamara, igiciro cyibi bikoresho kiri hejuru, kigabanya imikoreshereze yacyo ku isoko;kubwibyo, igiciro cyacyo gito kandi cyangirika krahisi niyo guhitamo neza hamwe na PBAT.
Icya gatatu: PLA
PLA (Acide Polylactique) izwi kandi nka polystumin.Umusaruro wa polystumin ni umwanda, kandi ibicuruzwa birashobora kwangirika, bigaragarira muri kamere.Kubwibyo, nibintu byiza byicyatsi kibisi.imwe.
Nubwo bimeze bityo ariko, hari byinshi bitagenda neza mubikorwa bifatika: PLA ifite ubukana bubi, kubura ubworoherane nubworoherane, imiterere ikomeye nubukonje, ugereranije imbaraga nke zishonga, umuvuduko muke wa kristaline, nibindi. Inenge zavuzwe haruguru zagabanije gukoresha mubikorwa byinshi.
Imiterere y’imiti ya PLA irimo ubwinshi bwa ester bonds, itera hydrophilicitike mbi nigipimo cyo kwangirika bigomba kugenzurwa.Byongeye kandi, igiciro cya PLA kiri hejuru, cyongera igiciro cyibikoresho fatizo kandi kigabanya kuzamura ubucuruzi bwacyo.Kubwibyo, PLA yahinduwe kubintu byinshi byavuzwe haruguru.
PBAT ifite imiterere yoroshye, ihindagurika rikomeye, hamwe nigihe gito cyo kwangirika;PLA ifite imiterere yoroheje, ubukana bubi, hamwe nigihe kirekire cyo gutesha agaciro.Kubwibyo, kuvanga byombi nuburyo bwiza cyane bwo kunoza imikorere.
Bane: Intangiriro y'ibikoresho bya PBAT / PLA
Gushonga kwa PBAT na PLA nuburyo bwo guhindura umubiri.Ingingo y'ingenzi ni ugusaba guhuza neza.Nyamara, gukemura kwa PBAT na PLA ni binini, bityo guhuza ni bibi, kandi biragoye kuvanga kimwe.
Kunoza ubwuzuzanye bwa PBAT na PLA nikibazo cyibanze.Igikoresho kimwe cyangwa byinshi bigomba kongerwaho kuvanga kuvanga kugirango tunoze neza imiterere ya PBAT na PLA.Ibikoresho bisanzwe bikoreshwa ni: plasitike, reaction, reaction, na polymer polymer ikomeye.
PLA na PBAT bifite imikorere yuzuzanya, hagomba rero kubaho igipimo cyiza cyiza cyimikorere yuzuye.
1. Umubare wa PLA uzamuka kugera kuri 40% kuri node.Kurambura ubukana bwibikoresho bigabanuka mbere hanyuma byiyongera.
2. Niba ibikubiye muri PLA birenze 70%, ibikoresho biroroshye cyane kandi ntibishobora guhurizwa muri firime.Kubwibyo, igipimo cya PLA na PBAT kigomba kugumaho nka 1: 1 ukurikije imiterere yinyongera.
Performance Imikorere itesha agaciro】
Igisubizo cyambere cyo kwangirika kwibintu ni uko hydrolyzed igisubizo cya molekile zamazi zinjira.Niba ari ibikoresho bya PBAT bitandukanye, biragoye kuyitesha agaciro kuko imiterere ya molekile ifite ester ikomeye.Molekile ya PLA irashobora kwangirika imbere mumazi.Kubwibyo, urwego rwo hejuru rwa PLA, niko kwangirika kwibintu byihuse.
