Intego n'impinduka mu gushushanya umupira w'ingufu

Rubber ifite ubushobozi bwo guhindagurika neza, ariko iyi mitungo y'agaciro itera ingorane zikomeye mu gukora ibicuruzwa. Iyo ubushyuhe bwa rubber idatangiye kugabanuka, ingufu nyinshi za mashini zikoreshwa mu guhindura ubushyuhe mu gihe cyo kuyitunganya, kandi imiterere ikenewe ntishobora kuboneka. Ikoranabuhanga ryo gutunganya rubber rifite ibisabwa kugira ngo rubber idahindagurika, nko kuvanga, muri rusange bisaba ubushyuhe bwa Mooney bwa dogere 60, no guhanagura rubber, bisaba ubushyuhe bwa dogere 40, Bitabaye ibyo, ntibizashoboka gukora neza. Amwe mu mavuta adashyushye arakomeye cyane, afite ubushyuhe bwinshi, kandi nta miterere y'ibanze kandi ikenewe mu buryo bwo kuyitunganya - ubushyuhe bwiza. Kugira ngo yuzuze ibisabwa mu buryo bwo kuyitunganya, rubber idashyushye igomba gushyirwa muri pulasitiki kugira ngo igabanye umuyoboro wa molekile kandi igabanye uburemere bwa molekile munsi y'ibikorwa bya mashini, ubushyuhe, imiti n'ibindi. Ibigize pulasitiki bitakaza ubushyuhe bwabyo by'agateganyo kandi bikaba byoroshye kandi bishobora guhindurwa. Dushobora kuvuga ko gushushanya rubber idashyushye ari ishingiro ry'izindi nzira z'ikoranabuhanga.
Intego yo gushushanya rubber mbisi ni uku: icya mbere, kubona urwego runaka rwa plasticity kuri rubber mbisi, bigatuma ikoreshwa mu kuvanga, guterura, gusohora, gushushanya, gukurura, ndetse n'ibisabwa mu bikorwa nk'urusyo rwa rubber n'ikorwa rya rubber ya sponge; Icya kabiri ni uguhuza plasticity ya rubber mbisi kugira ngo hakorwe ibikoresho bya rubber bifite ubuziranenge bungana.
Nyuma yo guhindurwa pulasitiki, imiterere y’umubiri n’imiti bya rubber mbisi nayo irahinduka. Bitewe n’imbaraga zikomeye za mekanike na ogisijeni, imiterere ya molekile n’uburemere bwa molekile bya rubber bizahinduka ku rugero runaka, bityo imiterere y’umubiri n’imiti nabyo birahinduka. Ibi bigaragazwa no kugabanuka k’ubudahangarwa, kwiyongera kwa pulasitiki, kwiyongera k’ubushonge, kugabanuka k’ubushyuhe bw’umuti wa rubber, no kunoza imikorere y’ibikoresho bya rubber. Ariko uko ubushyuhe bw’urubber mbisi bwiyongera, imbaraga za mekanike za rubber mbisi zigabanuka, guhinduka guhoraho kuriyongera, kandi ubushobozi bwo kudashira no kudasaza byombi biragabanuka. Kubwibyo, guhindurwa kwa rubber mbisi ni ingirakamaro gusa mu gutunganya rubber, kandi ntabwo bifasha imikorere ya rubber mbisi.
