Atlanta, GA - Kuva ku ya 30 Nzeri kugeza 2 Ukwakira, Hotel ya Omni muri Centennial Park izakira inama ya tekinike ya Polyurethanes 2024, izahuza abanyamwuga n’inzobere mu nganda za polyurethane ku isi. Iyi nama yateguwe n’ikigo cy’abanyamerika gishinzwe ubutunzi mu kigo cy’inganda za Polyurethanes (CPI), iyi nama igamije gutanga urubuga rw’amasomo y’uburezi no kwerekana udushya tugezweho muri chimie polyurethane.

Polyurethanes izwi nkimwe mubikoresho byinshi bya pulasitiki biboneka muri iki gihe. Imiterere yihariye yimiti ibemerera guhuza ibikorwa byinshi, gukemura ibibazo bigoye no kubumbabumbwa muburyo butandukanye. Uku guhuza n'imihindagurikire y’ibicuruzwa n’inganda n’abaguzi, byongera ihumure, ubushyuhe, no korohereza ubuzima bwa buri munsi.

Umusaruro wa polyurethanes urimo reaction yimiti hagati ya polyole-alcool ifite amatsinda arenga abiri ya hydroxyl-reaction na diisocyanates cyangwa polymeric isocyanates, byoroherezwa na catalizator hamwe ninyongeramusaruro. Ubwinshi bwa diisocyanates iboneka hamwe na polyole bifasha abayikora gukora ibintu byinshi byerekeranye nibikorwa byihariye, bigatuma polyurethanes ihuzwa ninganda nyinshi.

Polyurethanes iragaragara hose mubuzima bwa kijyambere, iboneka mubicuruzwa bitandukanye kuva kuri matelas no kuryama kugeza kubikoresho byo kubika, gutwika amazi, no gusiga amarangi. Zikoreshwa kandi muri elastomers iramba, nk'ibiziga bya roller, ibikinisho byoroshye byoroshye, hamwe na fibre yoroheje. Kuba bariho cyane bishimangira akamaro kabo mukuzamura imikorere yibicuruzwa no korohereza abaguzi.

Ubuhanga bwa chimie inyuma yumusaruro wa polyurethane burimo cyane cyane ibikoresho bibiri byingenzi: methylene diphenyl diisocyanate (MDI) na toluene diisocyanate (TDI). Izi mvange zifata amazi mubidukikije kugirango zibe inert polyureas ikomeye, yerekana ibintu byinshi kandi bihuza na chimie polyurethane.

Inama ya tekinike ya 2024 Polyurethanes izagaragaramo amasomo atandukanye agamije kwigisha abitabiriye iterambere rigezweho muri urwo rwego. Impuguke zizaganira ku buryo bugenda bugaragara, uburyo bushya bwo gukoresha, hamwe n’ejo hazaza h’ikoranabuhanga rya polyurethane, ritanga ubushishozi bw’inzobere mu nganda.

Mugihe inama yegereje, abayitabiriye barashishikarizwa kwishora mu rungano rwabo, gusangira ubumenyi, no gushakisha amahirwe mashya mu rwego rwa polyurethane. Iki gikorwa gisezeranya kuba igiterane gikomeye kubagize uruhare mugutezimbere no gukoresha ibikoresho bya polyurethane.
