Niki PVB？ & Niki PVB ikoreshwa?
Polyvinyl butyral (cyangwa PVB) ni resin ikoreshwa cyane mubisabwa bisaba guhuza bikomeye, kumvikana neza, guhuza ahantu henshi, gukomera no guhinduka.Itegurwa muri alcool ya polyvinyl ukoresheje reaction na butyraldehyde.Porogaramu nyamukuru ni ikirahure cyumutekano cyikirahure cyimodoka.Amazina yubucuruzi kuri PVB-firime arimo KB PVB, Saflex, GlasNovations, Butacite, WINLITE, S-Lec, Trosifol na EVERLAM.PVB iraboneka kandi nka 3D printer ya filament ikomeye kandi irwanya ubushyuhe kuruta aside polylactique (PLA) .Polyvinyl butyral (PVB) ifatwa nka acetal kandi ikorwa mubitekerezo bya aldehyde n'inzoga.Imiterere ya PVB irerekanwa hepfo, ariko muri rusange ntabwo yakozwe muburyo bwiza.Yakozwe muburyo buryo polymer ari uruvange rwa PVB, inzoga za polyvinyl (PVOH), hamwe na polyvinyl acetate nkuko bigaragara ku gishushanyo.Umubare ugereranije nibi bice bigenzurwa ariko mubisanzwe bigabanywa binyuze mumurongo wa molekile.Imiterere ya polymers irashobora gutezimbere mugucunga ibipimo byibice bitatu.
PVB isubirwamo (RPVB), izwi kandi ku izina rya Recycled Polyvinyl Butyral, ni uruhu rukomatanya rukozwe mu gutunganya ibirahuri by’ibirahure biva mu modoka zatawe zubaka ibirahure.Nkibikoresho bya polymeriki, uruhu rwa PVB nyuma yumuguzi rukoreshwa cyane cyane no gufunga, gupakira, ninganda zitwara ibinyabiziga.
Ni ukubera iki PVB itunganyirizwa ibikoresho biramba?
1.Icyuma cya PVB cyongeye gukoreshwa ibirenge bya karuboni bikubye inshuro 25 kurenza inkumi PVB.Ongera ubuzima bwibintu byibicuruzwa byacu.Amazi make, nta miti yuburozi, hamwe no kugenzura ibidukikije byiyemeje.
2.Mu gutandukanya, kweza, no guhindura, PVB yongeye gukoreshwa irashobora guhinduka mubikoresho byarangiye.Binyuze mu bundi buryo bwo gukora, hakozwe firime zitandukanye zoroshye, imyenda isize, hamwe nibikoresho byinshi.
3.Gukoresha ibi bikoresho bigabanya ikirere cya karubone ya precoat 80% ugereranije na latex gakondo.Amabati yose ya micro tuff yamashanyarazi ubu yakozwe na precoat yayo, bigabanya ingaruka kubidukikije cyane.
4. PVB isubirwamo ikozwe mugutunganya ibirahuri byumuyaga mumodoka yataye yubaka ikirahure.Guhindura rero ibi bintu bitigeze bisubirwamo mubintu byiza byibanze.Ibyo bivuze kugabanya imyanda yumuyaga, nibyiza kubidukikije.Mugihe kimwe, hindukira kumyanda kubikoresho, ibyo nabyo nibyiza kumubumbe wacu.
Kuki duhitamo ibikoresho bya PVB byongeye gukoreshwa?
1. Ibikoresho bya PVB nibidafite umwanda kandi birinda ubuhehere, biroroshye cyane koza imifuka yacu.
2. Kubera ko ibikoresho bya PVB bikomeye.Ibicuruzwa bikozwe muri PVB byongeye gukoreshwa birakomeye kandi birashobora kugwa.
3.Icyuma cyihariye cya PVB cyuruhu rwihariye rutanga ibintu byinshi muburyo bwagutse, kandi nuburyo bwiza kuri PVC.
4. PVB itunganijwe neza yangiza ibidukikije kandi ntacyo yangiza kubantu mugabanya ibirenge bya karubone mugihe byongera ubuzima bwibintu byibicuruzwa.Ntabwo ikubiyemo imiti yuburozi nka Dimethylformamide (DMF) na Dimethylfumarate (DMFu).
5. PVB yongeye gukoreshwa irimo Oya BPA, Nta Plastiseri, Nta Phthalates, ni umutekano.
6. PVB isubirwamo yongeye kwangirika, ni ibikoresho byangiza ibidukikije.
7. Ibicuruzwa bikozwe muri PVB byongeye gukoreshwa bisa neza cyane, bigororotse, byiza, birinda amazi kandi biramba.Abantu benshi bakunda ibi bikoresho.
8. Igiciro cya PVB cyongeye gukoreshwa ntabwo kiri hejuru cyane.Abaguzi benshi rero barashobora kwemera igiciro cyibicuruzwa bikozwe muri PVB yongeye gukoreshwa.
