Inganda zongera gutunganya inganda zigera kuri 1-3% mu turere twinshi, munsi yikigereranyo cya aluminium na PET.

Nigute polypropilene ikora hanze?

Polypropilene idahindagurika yangirika vuba iyo ihuye nimirasire ya UV, igacika intege kandi igahinduka ibara mumezi. Nyamara, ibikoresho bya UV stabilisateur byongerera ubuzima hanze imyaka 5 - imyaka 10 cyangwa irenga bitewe nikirere nikirere. Carbone umukara itanga ikiguzi cyiza cya UV kurinda porogaramu yihanganira ibara ry'umukara. HALS.

Niki gitera polypropilene gucika cyangwa kunanirwa?

Uburyo bukunze kunanirwa harimo guhangayikishwa n’ibidukikije biturutse ku guhura n’imiti hamwe no guhangayikishwa n’ubukanishi, kunanirwa ingaruka ku bushyuhe buke aho ibikoresho bigenda bisenyuka, kwangirika kw’ubushyuhe bitarenze ubushyuhe bwa serivisi busabwa, hamwe no kwangirika kwa UV mu bikorwa byo hanze bidahagaze neza. Guhitamo ibikoresho neza, gushushanya igice, no kugenzura imikorere igabanya ingaruka ziterwa no gutsindwa.

Ese polypropilene irimo imiti yangiza?

Amababi meza ya polypropilene agizwe rwose na atome ya karubone na hydrogen nta nyongeramusaruro. Ibicuruzwa byarangiye birashobora kuba birimo ibikoresho byo gutunganya, amabara, UV stabilisateur, flame retardants, cyangwa ibindi byongeweho bikora bitewe nibisabwa. Amabwiriza yubahirizwa hamwe nimpapuro zumutekano inyandiko zongeweho zose zihari. Ibiryo - kuvugana nubuvuzi - urwego polypropilene ikorerwa ibizamini bikomeye kugirango umutekano ukoreshwe.

Ibyingenzi

Polypropilene iri ku mwanya wa kabiri ku isi - plastiki yakozwe cyane, hamwe na toni zirenga miliyoni 70 zakozwe buri mwaka, zikurikirana polyethylene gusa mububyaza umusaruro wisi yose mugihe zitanga ubushyuhe bukabije hamwe n’imiti ihuza imiti.

Imiterere ya termoplastique yibikoresho ituma ubushyuhe bwinshi kandi buvugururahatabayeho kwangirika kwumutungo uhambaye, gushyigikira uburyo bunoze bwo gutunganya ibicuruzwa nuburyo butandukanye bwo gukora harimo kubumba inshinge, gusohora, no guhumeka.

Imiti irwanya aside, ibishingwe, hamwe nudukoko twangiza umubiri itandukanya polypropilene nubundi buryo, kuyigira nkenerwa mububiko bwimiti yinganda, gusukura ibikoresho, nibikoresho bya laboratoire aho guhuza ibikoresho bigaragaye ko ari ngombwa.

Porogaramu itangirira mubipfunyika (30% yumusaruro) ukoresheje ibinyabiziga (20%)kubikoresho byubuvuzi, imyenda, nibicuruzwa byabaguzi, hamwe na buri murenge ukoresha inyungu zumutungo wihariye ibikoresho bidashobora guhura nigiciro cyagereranijwe.
