Iriburiro:
Plastike ikoreshwa cyane mu nganda zitandukanye bitewe nuburyo bwinshi kandi bukoresha neza.Nyamara, gutwikwa kwabo bishobora guteza akaga, bigatuma kutagira umuriro ari igice cyingenzi cyubushakashatsi.Ubu bushakashatsi bwubushakashatsi bugamije gukora ubushakashatsi ku mikorere y’umuriro utandukanye mu kongera umuriro wa plastiki.
Uburyo:
Muri ubu bushakashatsi, twahisemo ubwoko butatu bukoreshwa cyane muri plastiki: polyethylene (PE), polypropilene (PP), na chloride polyvinyl (PVC).Buri bwoko bwa pulasitike bwakoreshwaga hamwe n’umuriro utandukanye w’umuriro, kandi ibintu birwanya umuriro byagereranijwe n’intangarugero zitavuwe.Ikirimi cya flame kirimo ammonium polyphosphate (APP), hydroxide ya aluminium (ATH), na melamine cyanurate (MC).
Uburyo bw'igerageza:
1. Gutegura Icyitegererezo: Ibigereranyo bya buri bwoko bwa plastike byateguwe ukurikije ibipimo bisanzwe.
2. Kuvura Flame Retardant: Guhitamo flame retardants (APP, ATH, na MC) byavanze na buri bwoko bwa plastike bukurikira ibipimo byasabwe.
3. Gupima umuriro: Ingero za pulasitike zavuwe kandi zitavuwe zakorewe umuriro ugurumana ukoresheje icyotezo cya Bunsen.Igihe cyo gutwika, ibirimi byakwirakwiriye, hamwe no kubyara umwotsi byaragaragaye kandi byandikwa.
4. Ikusanyamakuru: Ibipimo byarimo igihe cyo gutwika, igipimo cyo gukwirakwiza umuriro, no gusuzuma neza umusaruro w’umwotsi.
Ibisubizo:
Ibisubizo byibanze byerekana ko ibyuma bitatu byumuriro byazamuye neza umuriro wa plastiki.Ingero zavuwe zerekanye igihe kirekire cyane cyo gutwika kandi umuriro ugenda ukwirakwira ugereranije nicyitegererezo kitavuwe.Mubadindiza, APP yerekanye imikorere myiza kuri PE na PVC, mugihe ATH yerekanye ibisubizo bitangaje kuri PP.Kubyara umwotsi ntarengwa byagaragaye mu ngero zavuwe muri plastiki zose.
Ikiganiro:
Iterambere ryagaragaye mu kurwanya umuriro ryerekana ubushobozi bwaba barinda umuriro kugirango bongere umutekano wibikoresho bya plastiki.Itandukaniro ryimikorere hagati yubwoko bwa plastike hamwe na retardants ya flame bishobora guterwa nuburyo butandukanye mubigize imiti n'imiterere.Ubundi isesengura rirakenewe kugirango dusobanukirwe nuburyo bwibanze bushinzwe ibisubizo byagaragaye.
Umwanzuro:
Ubu bushakashatsi bwakozwe bushimangira akamaro ko kutagira umuriro muri plastiki kandi bugaragaza ingaruka nziza za ammonium polyphosphate, hydroxide ya aluminium, na melamine cyanurate nkibishobora gukumira umuriro.Ibyavuye mu bushakashatsi bigira uruhare mu iterambere ry’ibikoresho bya pulasitiki bitekanye bikoreshwa mu buryo butandukanye, kuva mu bwubatsi kugeza ku bicuruzwa by’abaguzi.
Ubundi bushakashatsi:
Ubushakashatsi bw'ejo hazaza bushobora gucukumbura uburyo bwiza bwo kugereranya umuriro, guhagarara igihe kirekire kwa plastiki zavuwe, hamwe n’ingaruka ku bidukikije by’abafite umuriro.
Mugukora ubu bushakashatsi, dufite intego yo gutanga ubumenyi bwingenzi mugutezimbere plastike yumuriro-retardant, guteza imbere ibikoresho bitekanye no kugabanya ingaruka ziterwa no gutwika plastike.
