Cyera, cyiza, cyoroshye, kandi cyiza, kigereranywa.
Abantu benshi bakunda ibintu byera, nibicuruzwa byabaguzi bikunze gukorwa byera. Mubisanzwe, abantu bagura ibintu byera cyangwa bambara imyenda yera bazitondera kutareka uruzitiro. Ariko hariho amagambo avuga ati: "Muri iyi isanzure ako kanya, wange ubuziraherezo." Nubwo washyizeho imbaraga ushyira mugumana ibyo bintu byanduye, bazahita bahinduka umuhondo bonyine. Mu cyumweru, umwaka, cyangwa imyaka itatu, wambara urubanza rwa terefone kugirango ukore buri munsi, kandi ishati yera utarambarwa muri wardrobe ituje ihindura umuhondo wenyine.
Mubyukuri, umuhondo wimyambarire ya fibre, inkweto za elastike, hamwe na terefone ya plastike nigaragaza gusaza Polymer, uzwi nkumuhondo. Umuhondo bivuga phenomenon yo gutesha agaciro, gutondeka, cyangwa kwambukiranya ibicuruzwa byibicuruzwa bya polymer mugihe cyo gukoreshwa, biterwa nubushyuhe, imirasire, ibitekerezo, bikavamo gushiraho amatsinda yimikorere yagiranye.
Aya matsinda y'amabara asanzwe ya karubone karubone inshuro ebyiri (c = c), amatsinda ya karubonyl (c = o), amatsinda ya Imane (C = N), nibindi. Iyo umubare wa karubone yahagaritswe karubone inshuro ebyiri ebyiri zigera kuri 7-8, zigaragara yumuhondo. Mubisanzwe, iyo ubonye ko ibicuruzwa bya polymer bitangiye guhindura umuhondo, igipimo cyumuhondo ukunda kwiyongera. Ni ukubera ko kwangiza polymers ari urunigi, kandi iyo gahunda yo gutesha agaciro itangira, gusenyuka kw'iminyururu ya molekile ni nka domino, hamwe na buri gice kigwa kuri umwe.
Hariho inzira nyinshi zo gukomeza ibikoresho. Ongeraho titanium dioxyde na fluostcent byera birashobora kuzamura neza ingaruka zera zibikoresho, ariko ntishobora kubuza ibikoresho kumurika. Kutinda umuhondo wa polymers, intagaro yoroheje, ibyuma byoroheje, abakozi bahingana, nibindi barashobora kongerwaho. Ubu bwoko bwinyongera irashobora gukuramo ingufu zakozwe numucyo wa ultraviolet mumirasire yizuba, uzana polymer gusubira muri leta ihamye. Kandi kurwanya ubushyuhe burashobora gufata imiti yubusa byakozwe na okiside, cyangwa guhagarika gutesha agaciro iminyururu ya polymer kugirango uhagarike urunigi rwo gutesha agaciro Polymer. Ibikoresho bifite ubuzima bwubuzima, kandi inyongera kandi zifite ubuzima bwubuzima. Nubwo inyongeramusaruro zirashobora gutinda neza igipimo cyumuhondo wa polymer, bo ubwabo bazananirwa buhoro mugihe cyo gukoresha.
Usibye kongeramo inyongera, birashoboka kandi gukumira polymer umuhondo uva mubindi bice. Kurugero, kugabanya gukoresha ibikoresho mubushyuhe bwinshi kandi bikaba ari ngombwa gushyira mu bikorwa urumuri rukurura ibikoresho mugihe ubikoresha hanze. Umuhondo ntugire ingaruka gusa kubigaragara, ariko nanone ukora ikimenyetso cyibikoresho byo gutesha agaciro cyangwa gutsindwa! Iyo wubatse ibikoresho birimo umuhondo uhagaze, abasimbuye bashya bigomba gusimburwa vuba bishoboka.
