PU ni iki?

I. Intangiriro ya PU

PU, cyangwa polyurethane, ni ibikoresho by’ubukorikori bigizwe ahanini na polyurethane. Uruhu rwa sintetike rwa PU ni ibikoresho by’uruhu bifatika kandi bifite imiterere myiza kandi biramba kurusha uruhu rusanzwe.

Uruhu rwa PU rukozwe mu buryo bwa sintetike rufite ibintu byinshi bitandukanye, birimo gukora intebe z'imodoka, sofa, amasakoshi, inkweto, n'imyenda, n'ibindi. Ruraryoshye mu buryo bwiza, rworoshye, rworoshye gusukura no kubungabunga, kandi rugabanya ikenerwa ry'uruhu rw'inyamaswa, bityo rukaba rwujuje ibisabwa ku bidukikije bibuza inyamaswa guhohotera.

II. Isesengura ry'ibikoresho bya PU

1. Imiterere

Igice cy'ingenzi cy'uruhu rwa sintetike rwa PU ni polyurethane, ikorwa no gukorana kwa polyether cyangwa polyester na isocyanate. Byongeye kandi, uruhu rwa sintetike rwa PU rufite kandi ibikoresho byo kuzuza, pulasitiki, irangi, n'ibindi bikoresho by'inyongera.

2. Isura

Uruhu rwa PU rukozwe mu nganda rufite imiterere n'amabara menshi, kandi rushobora kwigana imiterere itandukanye y'uruhu nk'ingona, inzoka, n'ibishishwa by'amafi kugira ngo ruhuze n'ibyo ibicuruzwa bitandukanye bisaba.

3. Imiterere ifatika

Uruhu rwa sintetike rwa PU rufite imiterere myiza cyane nko gukomera, kudashira, kudashira amazi, no koroha. Nanone biroroshye gusukura no kubungabunga kurusha uruhu rusanzwe, bigatuma ruramba.

4. Agaciro k'ikoreshwa

Ugereranyije n'uruhu rusanzwe, uruhu rwa PU rufite ibyiza bimwe na bimwe nko kugabanuka kw'igiciro, ikiguzi gito cyo gukora, no kudakenera uruhu rw'inyamaswa, bigatuma ruhinduka amahitamo meza mu buzima bw'imijyi ya none.

Muri make, uruhu rwa sintetike rwa PU ni ikintu cyiza cyane kandi gifite ubwiza, imikorere myiza, n'igiciro cyiza, bigatuma rukundwa cyane ku isoko. Uko ikoranabuhanga ritera imbere n'ibikenewe ku isoko bihinduka, uruhu rwa sintetike rwa PU ruzagira akamaro kanini mu gihe kizaza mu nzego zitandukanye nko mu modoka, mu bikoresho byo mu nzu, mu myenda no mu masakoshi, n'ibindi byinshi.
