Hamwe niterambere ryiterambere ryibihe, ubuzima bwabantu bwarahindutse cyane, kandi gukoresha ibikoresho bishya bitandukanye byarushijeho kwiyongera. Kurugero, PVC naEVAibikoresho bikoreshwa cyane mubuzima bwubu, ariko abantu benshi byoroshye kubitiranya. . Ibikurikira, reka twumve itandukaniro riri hagati yibikoresho bya PVC na EVA.
1. Kugaragara nuburyo butandukanye:
PVC ku mugabane w'Ubushinwa irashobora kugabanywamo ubwoko bubiri: uburozi buke kandi butangiza ibidukikije kandi butagira uburozi kandi bwangiza ibidukikije. Ibikoresho bya EVA nibikoresho byose byangiza ibidukikije. Ubuso bwa EVA bworoshye; ubukana bwayo bukomeye burakomeye kuruta ubwa PVC, kandi yumva ifatanye (ariko nta kashe iri hejuru); ni cyera kandi kibonerana, kandi kibonerana Hejuru, ibyiyumvo no kumva bisa cyane na firime ya PVC, bityo rero hagomba kwitonderwa kubitandukanya.
2. Inzira zitandukanye:
PVC ni thermoplastique resin polymerized na vinyl chloride ikorwa nuwatangije. Ni homopolymer ya vinyl chloride. Vinyl chloride homopolymer na vinyl chloride copolymer hamwe hamwe bita vinyl chloride resin. PVC yahoze ikorwa cyane muri plastiki rusange-yisi yose kandi yarakoreshejwe cyane. Inzira ya molekuline ya EVA (Ethylene vinyl acetate copolymer) ni C6H10O2 naho uburemere bwayo ni 114.1424. Ibi bikoresho bikoreshwa nka firime zitandukanye, ibicuruzwa byinshi, ibishishwa bishyushye hamwe na polymer modifiseri.
3. Ubwitonzi butandukanye nubukomere: Ibara risanzwe rya PVC ni umuhondo muto, byoroshye kandi birabagirana. Gukorera mu mucyo biruta polyethylene na polystirene, ariko birutwa na polystirene. Ukurikije ingano yinyongera, igabanijwemo chloride yoroshye kandi ikomeye. Ibicuruzwa byoroshye biroroshye kandi birakomeye kandi byunvikana, mugihe ibicuruzwa bikomeye bifite ubukana burenze ubwinshi bwa polyethylene. , kandi munsi ya polypropilene, kwera bizabera aho bihurira. EVA (Ethylene vinyl acetate copolymer) yoroshye kuruta PVC.
4. Ibiciro biratandukanye:
Ibikoresho bya PVC: Igiciro kuri toni kiri hagati ya 6.000 na 7,000. Ibikoresho bya EVA bifite ubunini butandukanye nibiciro. Igiciro ni metero 2000 / kubic.
5. Ibintu bitandukanye biranga:
PVC ifite ibikoresho byiza byo gukwirakwiza amashanyarazi, birashobora gukoreshwa nkibikoresho bito bito, kandi imiti ihamye nayo ni nziza. Bitewe nubushyuhe buke bwumuriro wa polyvinyl chloride, gushyushya igihe kirekire bizatera kubora, kurekura gaze ya HCl, no guhindura amabara ya chloride polyvinyl. Kubwibyo, ikoreshwa ryayo riragufi, kandi ubushyuhe bwo gukoresha buri hagati ya dogere -15 na 55. EVA irakomeye mubushyuhe bwicyumba. Iyo bishyushye, bishonga kurwego runaka bigahinduka amazi ashobora gutemba kandi akagira ububobere runaka.
