Itandukaniro ryingenzi cyane hagati ya plastiki na reberi nuko ihindagurika rya plastike ari ihindagurika rya plastike, naho reberi ni ihindagurika.Muyandi magambo, plastike ntabwo yoroshye kugarura uko yari imeze nyuma yo guhinduka, mugihe reberi yoroshye.Elastique ya plastike ni nto cyane, mubisanzwe munsi ya 100%, mugihe reberi ishobora kugera 1000% cyangwa irenga.Byinshi mubikorwa byo kubumba bya plastiki birarangiye kandi ibicuruzwa birarangiye, mugihe uburyo bwo kubumba reberi busaba inzira yibirunga.
Plastike na reberi byombi ni ibikoresho bya polymer, bigizwe ahanini na atome ya karubone na hydrogène, kandi bimwe birimo ogisijeni nkeya, azote, chlorine, silikoni, fluor, sulfuru nandi atome.Bafite ibintu byihariye nibikoreshwa bidasanzwe.Plastike ku bushyuhe bwicyumba Irakomeye, irakomeye cyane, kandi ntishobora kuramburwa no guhindurwa.Rubber ntabwo iri hejuru mubukomere, bworoshye, kandi irashobora kuramburwa kugirango ibe ndende.Irashobora gusubizwa kumiterere yumwimerere iyo ihagaritse kurambura.Ibi biterwa nuburyo bwabo butandukanye.Irindi tandukaniro nuko Plastike ishobora gukoreshwa kandi igakoreshwa inshuro nyinshi, mugihe reberi idashobora gukoreshwa neza.Irashobora gutunganyirizwa gusa muri reberi yagaruwe mbere yuko ikoreshwa.Imiterere ya plastike irenga dogere 100 kugeza kuri dogere 200 nuburyo bwa reberi kuri dogere 60 kugeza 100.Mu buryo nk'ubwo, plastiki ntabwo irimo reberi.
Nigute dushobora gutandukanya plastiki na plastiki?
Duhereye ku gukoraho, reberi ifite gukorakora byoroshye, byoroshye kandi byoroshye, kandi bifite urwego runaka rwa elastique, mugihe plastiki idakomeye rwose kandi ifite urwego runaka rwo gukomera kuko birakomeye kandi byoroshye.
Uhereye kumurongo uhangayitse, umurongo wa plastike werekana modulus yo hejuru murwego rwo gutangira impagarara.Umurongo utambitse ufite izamuka ryinshi, hanyuma umusaruro, kurambura no kuvunika bibaho;reberi isanzwe ifite intambwe ntoya.Imihangayiko igaragara irazamuka, hanyuma ikinjira mucyiciro cyoroheje cyo kuzamuka, kugeza igihe umurongo-uhangayikishije umurongo werekana ahantu hahanamye cyane iyo bigiye gucika
Urebye kuri termodinamike, plastike iri munsi yubushyuhe bwikirahure bwibintu mubipimo byubushyuhe, mugihe reberi ikora muburyo bworoshye cyane hejuru yubushyuhe bwikirahure.
