“Kuvugururwa” na “gusubiramo” ni ibintu bibiri by'ingenzi ariko bikunze kwitiranya kurengera ibidukikije. Iyo bigeze ku ruhu rwa PU, uburyo bwibidukikije hamwe nubuzima bwubuzima buratandukanye rwose.
Mu ncamake, Kuvugurura byibanda kuri "ibikoresho fatizo biva mu isoko" - aho biva kandi niba bishobora guhora byuzuzwa. Recyclable yibanda kuri "ibicuruzwa birangira-ubuzima" - niba bishobora kongera gukoreshwa mubikoresho fatizo nyuma yo kujugunywa. Ubu tuzajya tuvuga birambuye kubyerekeye itandukaniro ryihariye riri hagati yibi bitekerezo byombi nkuko bikoreshwa ku ruhu rwa PU.
1. Uruhu rushya rwa PU (uruhu rwa bio rushingiye ku ruhu).
• Niki?
'Bio-ishingiye kuri PU uruhu' ni ijambo ryukuri kubijyanye nimpu za PU zishobora kuvugururwa. Ntabwo bivuze ko ibicuruzwa byose bikozwe mubinyabuzima. Ahubwo, bivuga ko bimwe mubikoresho fatizo bya chimique bikoreshwa mugukora polyurethane bikomoka kuri biomass ishobora kuvugururwa aho kuba peteroli idasubirwaho.
• Nigute 'gusubirwamo' bigerwaho?
Kurugero, isukari iva mubihingwa nkibigori cyangwa ibisheke bisemburwa hakoreshejwe ikoranabuhanga kugirango habeho imiti ishingiye kuri bio, nka propylene glycol. Aba bahuza noneho bahindurwamo polyurethane. Uruhu rwa PU ruvuyemo rurimo igipimo runaka cya 'bio-ishingiye kuri karubone'. Ijanisha nyaryo riratandukanye: ibicuruzwa kumasoko biri hagati ya 20% kugeza hejuru ya 60% bio-ishingiye kuri bio, bitewe nimpamyabumenyi yihariye.
2. Uruhu rwa PU rusubirwamo
• Niki?
Uruhu rwa PU rushobora gukoreshwa bivuga ibikoresho bya PU bishobora kugarurwa hakoreshejwe uburyo bwumubiri cyangwa imiti nyuma yo kujugunywa hanyuma bigakoreshwa kugirango bitange ibicuruzwa bishya.
• Nigute "recyclability" igerwaho?
Isubiramo ryumubiri: Imyanda ya PU irajanjagurwa hanyuma igahinduka ifu, hanyuma ikavangwa nkuzuza muri PU nshya cyangwa ibindi bikoresho. Nyamara, ibi mubisanzwe bitesha agaciro ibintu bifatika kandi bifatwa nkibimanuka byongeye gukoreshwa.
Gutunganya imiti: Binyuze mu buhanga bwa depolymerisation ya chimique, molekile ya PU ndende-iminyururu igabanyijemo imiti yumwimerere cyangwa shya nka polyoli. Ibi bintu birashobora gukoreshwa nkibikoresho byisugi byinkumi kugirango bikore ibicuruzwa byiza bya PU. Ibi byerekana uburyo buhanitse bwo gufunga-gusubiramo.
Isano Hagati Yombi: Ntibisanzwe, Birashobora guhuzwa
Ikintu cyiza cyane cyangiza ibidukikije gifite ibintu byombi "bishobora kuvugururwa" na "recyclable". Mubyukuri, ikoranabuhanga riratera imbere muri iki cyerekezo.
Urugero rwa 1: Gakondo (Ntisubirwamo) Nyamara irashobora gukoreshwa
Yakozwe hifashishijwe ibikoresho fatizo bishingiye kuri peteroli ariko ikorwa muburyo bwo gutunganya imiti. Ibi bisobanura uko ibintu bimeze muri iki gihe "impu za PU zishobora gukoreshwa."
Urugero rwa 2: Kuvugururwa ariko ntibisubirwe
Yakozwe hifashishijwe ibikoresho fatizo bio, ariko imiterere yibicuruzwa bituma gutunganya neza bigoye. Kurugero, ihujwe rwose nibindi bikoresho, bigatuma gutandukana bigoye.
Urugero rwa 3: Isubirwamo kandi risubirwamo (Leta idasanzwe)
Yakozwe hifashishijwe ibikoresho fatizo bio kandi bigenewe gukoreshwa neza. Kurugero, ibikoresho-bimwe bya termoplastique PU bikozwe mububiko bushingiye kuri bio bigabanya imikoreshereze yumutungo wimyanda mugihe winjiye mumashanyarazi nyuma yo kujugunywa. Ibi byerekana paradigima yukuri "Cradle to Cradle".
Incamake n'ibyifuzo byo guhitamo ：
Mugihe uhisemo, urashobora guhitamo ukurikije ibidukikije byihutirwa:
Niba uhangayikishijwe cyane no kugabanya ikoreshwa rya lisansi y’ibicuruzwa n’ibyuka bihumanya ikirere, ugomba kwibanda ku “ruhu rushya / bio rushingiye ku ruhu rwa PU” hanyuma ukareba ibyemezo byarwo bishingiye kuri bio.
Niba uhangayikishijwe cyane n’ingaruka ku bidukikije nyuma yubuzima bwibicuruzwa kandi ukirinda kujugunya imyanda, ugomba guhitamo “uruhu rwa PU rusubirwamo” kandi ukumva inzira zabwo zikoreshwa kandi birashoboka.
Guhitamo kwiza cyane ni ugushakisha ibicuruzwa bihuza byombi bio-ishingiye ku bintu hamwe n'inzira zisobanutse neza, nubwo ubwo buryo bukomeza kuba buke ku isoko rya none.
Twizere ko, ibi bisobanuro bigufasha gutandukanya neza ibi bitekerezo byombi byingenzi.
