Igihe cy'itumba, twese tuzi ko iki kintu kuri plastiki nyuma yimbeho kizacika intege, niyihe mpamvu?

Plastike nikintu nyamukuru kigizwe na macromolecular, macromolecules irangwa nubushyuhe buke iyo kugenda gahoro, ubushyuhe bwinshi, kugenda byihuse.Mu gihe c'itumba, ingendo ya molekile iratinda, iyo plastike ikoresheje imbaraga zo hanze, guhindura ibintu, bitewe na molekile igenda gahoro, imbaraga zo hanze ntizoroshye guhita (kuringaniza imihangayiko y'imbere) cyangwa zikoreshwa (friction ya molekulari), bityo bikunda guhangayikishwa cyane, Iyo guhangayika kwimbere kurwego runaka, macromolecules kumenetse, gukurura ibice, ibice bizagaragazwa no guhangayikishwa no gukwirakwiza plastike kumenetse.

Inzira: Muri rusange, ubwinshi bwamazi yatewe mumufuka arashobora kugabanya kuvunika.

Ikoreshwa cyane mu nganda za elegitoroniki, moteri, kumurika, insinga za mudasobwa, ibikinisho bya elegitoroniki nibindi bicuruzwa, gutunganya imirongo ya kabili kumato, gutunganya imiyoboro ya peteroli yibikoresho bya mashini, no gupakira amagare cyangwa guhuza ibindi bintu.Igishushanyo mbonera cyumubiri, igihe kirekire cyo gukora.Santimetero 7.Kurwanya ruswa nziza, kubika neza, ntibyoroshye gusaza, no kwihangana gukomeye.Oval, umutwe muto ukuraho inzitizi kandi byoroshye kunyura mubice bitagira impande zikarishye.

Ibyiza ni:

1. Indobo yuzuye, isesengura ryimbere yimbere, imwe kandi ikomeye, imbaraga zo kuruma.

2. Gukomera karuvati, niko karuvati ntoya, hamwe nigishushanyo mbonera cyumuntu gihagarika ibintu kugwa.

3. Impera ya karuvati ya kabili ifite ibikoresho byambukiranya amenyo anti-skid, byoroshye kuyishyiraho no kuyitwara.

4. Ubuso bwa karuvati ya kabili nugufunga biroroshye, nta burr bigaragara, kandi ntibyoroshye gushushanya uruhu.

5. Ikariso ya kabili ikanda hamwe nubuhanga buhanitse, ibikoresho birasobanutse, gukomera birakomeye, ntabwo byoroshye kurekura iyo byometse, ntibyoroshye kunyerera, ntibyoroshye kumeneka
