Nigute imyenda ya RPET ikorwa?

RPET isubirwamo polyethylene terephthalate, nikintu cyangiza ibidukikije.

Igikorwa cyo gukora RPET gikozwe mumibabi ya polyester yataye, nkamacupa ya plastike yimyanda. Ubwa mbere, sukura imyanda neza kandi ukureho umwanda. Noneho kumenagura no gushyushya kugirango uhindure uduce duto. Ibikurikiraho, ibice byashongeshejwe kandi bigashya, ifu yamabara yongeweho, kandi irambuye kandi inonosorwa binyuze mumashini izunguruka kugirango itange fibre ya RPET

Umusaruro wa t-shati ya rPET urashobora kugabanywamo ibice bine byingenzi: gutunganya ibikoresho bibisi → kuvugurura fibre → kuboha imyenda → gutunganya-kwambara.

1. Kugarura ibikoresho bibisi no kwitegura

• Icyegeranyo cy'amacupa ya plastike: Kusanya amacupa ya PET ukoresheje imyanda itunganyirizwamo abaturage, supermarket revers logistique cyangwa ibigo byabigize umwuga byo gutunganya ibicuruzwa (toni zigera kuri miriyoni 14 z'amacupa ya PET bikorerwa ku isi buri mwaka, kandi 14% gusa ni byo byongera gukoreshwa).

• Isuku no kumenagura: Amacupa ya pulasitike yongeye gukoreshwa atondekwa mu ntoki / mu buryo bwa mashini (kuvanaho umwanda, ibikoresho bitari PET), kuvanaho ibirango hamwe na capita (cyane cyane ibikoresho bya PE / PP), koza kandi ukureho amazi asigaye hamwe nibara, hanyuma ubijanjagure mo ibice 2-5cm.

2. Kuvugurura fibre (umusaruro wa RPET)

• Gushonga gushonga: Nyuma yo gukama, ibice bya PET bishyushye kugeza 250-280 ℃ kugirango bishonge, bigizwe na polimeri ishonga.

• Gushushanya kuzunguruka: Gushonga bisohoka mu mugezi mwiza unyuze ku isahani ya spray, hanyuma nyuma yo gukonjesha no gukira, ikora fibre ngufi ya polyester yongeye gukoreshwa (cyangwa igahita ihindurwamo filime ikomeza).

• Kuzunguruka: fibre ngufi ikozwe mumyenda ya RPET binyuze mu guhuza, gusibanganya, ubudodo bubi, ubudodo bwiza nibindi bikorwa (bisa nuburyo bwa mbere bwa PET, ariko ibikoresho bibisi byongeye gukoreshwa).

3. Kuboha imyenda no gutunganya imyenda

• Ububoshyi bw'imyenda: Urudodo rwa RPET rukozwe mu mwenda uboshye binyuze mu mashini izenguruka / kuboha imashini ihinduranya (ijyanye n'inzira y'imyenda isanzwe ya polyester), ishobora gukorwa mu ngingo zitandukanye nk'ibisanzwe, pique, urubavu, n'ibindi.

• Nyuma yo gutunganya no kudoda: bisa na T-shati isanzwe, harimo gusiga irangi, gukata, gucapa, kudoda (urunigi rw'urunigi / inkombe), ibyuma hamwe nizindi ntambwe, hanyuma ugakora T-shati ya RPET.

RPET T-shirt nigicuruzwa gisanzwe cyo kugwa "ubukungu bwa plastiki butunganya". Muguhindura imyanda ya plastike mumyambaro, hitabwa kubikenewe byo kurengera ibidukikije nagaciro keza.
