Igice cya 1: Ibisobanuro Ibisobanuro - Ibisobanuro na Scope
1.1 Uruhu rwa PU: Uruhu rwa kera rushingiye ku buhanga
Igisobanuro: Uruhu rwa PU, cyangwa uruhu rwa polyurethane, ni ibikoresho byakozwe n'abantu bikozwe hamwe na polyurethane (PU) nk'igitambaro cyo hejuru, gifatanye na substrate zitandukanye (cyane cyane polyester cyangwa ipamba). Nibicuruzwa byihariye, bisobanuwe mubuhanga.
Indangamuntu yibanze: Nijambo rya tekiniki ryerekana neza ibintu bigize imiti (polyurethane) nuburyo (ibikoresho bifatika).
1.2 Uruhu rwa Vegan: Guhitamo Abaguzi
Igisobanuro: Uruhu rwa Vegan ni ijambo ryo kwamamaza no kwitwara neza, ntabwo ari tekiniki. Yerekeza ku kintu icyo ari cyo cyose cy’uruhu kidakoresha ibikoresho cyangwa ibikomoka ku nyamaswa. Impamvu nyamukuru itera ni ukwirinda kugirira nabi no gukoresha inyamaswa.
Indangamuntu yibanze: Nijambo ryumutaka ryerekana icyiciro cyibicuruzwa byubahiriza amahame y’ibikomoka ku bimera. Ingano yacyo ni ngari cyane; igihe cyose cyujuje amahame mbwirizamuco ya "idafite inyamaswa," uruhu urwo arirwo rwose rushobora gufatwa nkibikomoka ku bimera, hatitawe ku kuba ibikoresho shingiro ari polymer yimiti cyangwa ibikoresho bishingiye ku bimera. 1.3 Itandukaniro ryingenzi: Ikoranabuhanga nimyitwarire
Ngiyo urufatiro rwo gusobanukirwa itandukaniro ryombi. Uruhu rwa PU rukubwira "icyo rukozwe," mugihe uruhu rwibikomoka ku bimera rukubwira "icyo rubuze n'impamvu rwakozwe."
Igice cya 2: Uburyo bwo gukora ninkomoko yibikoresho - Kuva kuri molekile kugeza kubikoresho
2.1 Gukora uruhu rwa PU: Igicuruzwa cyinganda za peteroli
Gukora uruhu rwa PU ni inzira igoye ya chimique, ikomoka ku bicanwa bya peteroli (peteroli).
Gutegura Substrate: Icya mbere, substrate yimyenda, mubisanzwe polyester cyangwa ipamba, irategurwa, isukurwa, kandi iravurwa.
Gutegura ibishishwa: Ibice bya polyurethane bishonga mumashanyarazi (gakondo DMF-dimethylformamide, ariko bigenda byiyongera, bishingiye kumazi) hamwe namabara, inyongeramusaruro, nibindi byongeweho kugirango bibe bivanze.
Gupfundikanya no Gukomera: Ibishishwa bifatanyirijwe hamwe kuri substrate, hanyuma bigakurikirwa no kwiyuhagira mu bwogero bw’amazi (solvent no guhana amazi), bigatuma PU resin ikora firime yoroheje ifite imiterere ya microporome.
Nyuma yo gutunganywa: Nyuma yo gukaraba no gukama, gushushanya (gukora uruhu rwuruhu), gucapa, no gutwikira hejuru (kugirango wongere amaboko no kwambara birwanya) birakorwa, hanyuma ibicuruzwa byarangiye bikarangizwa.
Inkomoko Incamake: Ibikoresho bya peteroli bidasubirwaho nibikoresho byibanze byuruhu rwa PU.

Ubwumvikane: Kuri uru rwego, uruhu rwa PU nimpu zose zikomoka ku bimera nizo zatsinze neza. Birinda rwose kubaga no gukoresha inyamaswa mu nganda z’uruhu kandi bagahuza n’ibisabwa n’imyitwarire y’ibikomoka ku bimera.
4.2 Ingaruka ku bidukikije (Kuramba) - Isuzuma ryubuzima bwuzuye ni itegeko
Uruhu rwa PU (rushingiye kuri peteroli):
Ibibi: Ibikoresho byibanze byingenzi ni peteroli idasubirwaho. Umusaruro ukoreshwa cyane kandi ushobora kuba urimo imiti yangiza imiti (nubwo PU ishingiye kumazi igenda ikundwa cyane). Ikibazo gikomeye nuko idashobora kubora. Nyuma yigihe cyibicuruzwa, bizaguma mumyanda mumyaka amagana kandi birashobora kurekura microplastique. Ibyiza: Ugereranije n’umusaruro gakondo w’uruhu (uhumanya cyane, utwara amazi menshi, kandi usaba ubworozi), uburyo bwo kububyaza umusaruro busanzwe bufite imyuka mike ya karuboni, ikoreshwa ry’amazi, n’imikoreshereze y’ubutaka.
Uruhu rwa Bio rushingiye ku bimera:
Ibyiza: Gukoresha imyanda iva mu buhinzi (nk'amababi y'inanasi na pomasi ya pome) cyangwa biomass ishobora kuvugururwa vuba (mycelium na cork) bigabanya gushingira kuri peteroli kandi bigafasha gutunganya umutungo. Ibidukikije byangiza ibidukikije muri rusange biri hasi. Ibikoresho byinshi byibanze birashobora kubora.
Inzitizi: "Biodegradability" ntabwo ari byimazeyo. Impu nyinshi zishingiye kuri bio zisaba bio-ishingiye kuri polymer kugirango igere kuramba, akenshi bivuze ko ishobora kuba ifumbire mvaruganda gusa aho kubora vuba mubidukikije. Umusaruro munini w'ubuhinzi urashobora kandi gukubiyemo ibibazo bijyanye nudukoko twangiza udukoko, ifumbire, n’imikoreshereze yubutaka.
Ubushishozi bw'ingenzi:
"Ibimera" ntibingana "bitangiza ibidukikije." Isakoshi ya PU ikozwe muri peteroli, mugihe ibikomoka ku bimera, birashobora kugira igiciro kinini cyibidukikije mubuzima bwayo bwose. Ku rundi ruhande, umufuka wakozwe mu myanda yinanasi, nubwo udushya twangiza ibidukikije, ntushobora kuba igihe kirekire nkumufuka wa PU, biganisha kujugunywa vuba n’imyanda isa. Ibicuruzwa byose byubuzima bigomba gusuzumwa: kugura ibikoresho fatizo, kubyara umusaruro, gukoresha, no guta ubuzima bwa nyuma.
