Mubisanzwe, ni ubuhe bwoko bwa maquillage dushobora kugura mububiko?Ikozwe mu mpu zinyamanswa, PU uruhu rwubukorikori, PVC uruhu rwimbaraga？
Yego, mubyukuri bikozwe muri ibyo bikoresho.Ariko - PVC ni plastiki cyane, uruhu rwinyamaswa ruhenze kandi ntabwo ari ubugome;Isuzuma ryuzuye, uruhu rwa PU nuguhitamo neza kubiciro buke;Nubwo PU ifite inyungu igereranya, abakobwa ntibasa nkaho bahitamo kimwe gusa kandi abaguzi bashaka kugura ibintu byinshi byangiza ibidukikije kandi bifite ubuzima bwiza.Dufite amahitamo meza?
Igisubizo ni yego.Mu myaka yashize, uruhu rw’ibikomoka ku bimera rwatoneshejwe n’ibicuruzwa n’abacuruzi.Uruhu rushya, ibikomoka ku bimera hamwe n’ibicuruzwa bitunganijwe neza byerekana uruhu rwiza kandi rwiza mugihe bigabanya kwangiza ibidukikije.Kandi igiciro kiri hasi cyane kurenza uruhu rwinyamaswa
Rivta yunganira abaguzi benshi gukoresha ibikoresho byuruhu rwibikomoka ku bimera.Urugero:PVB.PVB isubirwamo (RPVB), izwi kandi ku izina rya Recycled Polyvinyl Butyral, ikoreshwa mu kirahure cyanduye (nk'amadirishya y'imodoka) nk'ibikoresho fatizo by'ibicuruzwa byabo. Ni uruhu rukora rukora rukozwe mu gutunganya ibirahuri by'ibirahure biva mu modoka zatawe zubaka ikirahure.
Hano hari imyanda myinshi ya PVB iboneka kwisi yose.Mu Burayi honyine, iki kirundo cy'imyanda ipima ibiro birenga miliyari 1.5, ibyo byiyongera hamwe n'uburemere bumwe buri mwaka, bisa n'iminara 150 ya Eiffel.Buri mwaka, imodoka zirenga miriyoni 25 zigera ku ndunduro yazo zikoreshwa ku isi yose, iyi myanda y’inganda yahoze itabwa cyangwa igatwikwa, ikaba imaze igihe ari ikibazo cy’ibidukikije, hanyuma igahindura kandi igakoresha ibyo bikoresho byahoze bitavugwa mu rwego rwo hejuru ibikoresho fatizo nintererano nini mubukungu bwizunguruka.
Bigereranijwe ko buri modoka ishobora gutanga hafi 2,6 kg ya PVB.Kuri buri tone ya RPVB, irashobora kuzigama toni 17 za CO2, na toni 53 zo gukoresha amazi.
Uruhu rwa PVB rwongeye gukoreshwa ntabwo rufite uburozi, imiterere yihariye itanga ibintu byinshi muburyo bukoreshwa.Ibara ryiza ryamabara yakozwe muri PVB itunganijwe neza irasa neza cyane, igororotse, nziza, itagira amazi kandi iramba, yakiriwe neza mumitako yacu, imitako yo kwisiga yo mu rwego rwo hejuru.
Dutangiza izi manza zakozwe muri Recycled PVB, ariko uburyo buratandukanye rwose:
1.Mini yerekana ibara ry'umuhondo igaragara neza;Imiterere ya shell irashobora kugabanya ingano yo hanze no kwagura umwanya wimbere;Bihujwe nubushobozi bworoshye kandi bunini ingingo ebyiri;Icy'ingenzi ni uko ari nziza cyane.
2. Ikariso nini yerekana umuhondo yerekana idirishya risobanutse.ikidasanzwe nuko twagerageje igicucu cyicyatsi kibisi mbere yo gutura kuri uyu muhondo wera;
3.Ibara ryambaye imyenda yijimye yambaye imyenda ibiri yo kwisiga.Hano hari imirongo ibiri yuzuye yimifuka yubugari butandukanye kugirango ufate urwego rutandukanye rwo kwisiga, ndetse n'amakaramu y'ijisho, ijisho, n'ibindi. Hepfo, hari umwanya uhagije wo kubika amacupa manini, igitambaro, masike nibindi bintu;
