Imiyoboro y'Ubuhanga yo Kwagura Beto Ifite Ibifunga bya Polyurethane
Inyubako za sima zikomeza kwaguka no gucikagurika bitewe n’ihindagurika ry’ubushyuhe, impinduka z’ubushuhe, imitwaro y’imodoka, n’ingendo z’inyubako. Iyo hatabayeho kwaguka neza, ibyuma binini bya sima biracika, bigatuma amazi yinjira, ibyuma bikomeza kwiyongera bikangirika, kandi inyubako ihenze ikangirika.
Ifu ifunga polyurethane ikora neza cyane ku ngingo za beto ni imwe mu ngamba nziza zo kurinda ingingo zagutse mu gihe ikomeza koroha mu gihe cy'impinduka zihinduka.
Iyi mfashanyigisho ya tekiniki isobanura byose injeniyeri, ba rwiyemezamirimo, abakwirakwiza ibicuruzwa, n'abayobozi b'imishinga bagomba kumenya ku bijyanye no guhitamo no gushyiramo ibifunga bya polyurethane mu miyoboro yo kwagura sima, harimo uburyo bwo kuyishyiraho, ubushobozi bwo kuyitwara, uburyo bwo kuyitunganya, uburyo busanzwe bwo gucika intege, n'uburyo bwiza bwo kuyibungabunga.
Waba urimo gufunga imihanda minini, ububiko, aho imodoka zihagarara, ibibuga by'indege, hasi mu nganda, cyangwa mu nyubako z'ubucuruzi, iyi nyandiko izagufasha kugera ku nyubako ziramba kandi zidashobora kugwa amazi kandi zimara imyaka myinshi.
Impamvu ibifunga bya Polyurethane ari byo bipimo ngenderwaho bya zahabu mu kwagura imiyoboro ya beto
Imiyoboro ya sima isaba byinshi kuruta kuzuza icyuho gusa.
