Hamwe nabantu ba none bahuze mubuzima hamwe numuvuduko mwinshi wakazi, ireme ryibitotsi rirakomeye.Abantu benshi bibasiwe cyane n’umwanda w’urusaku kubera ikibazo cy’imibereho yabo, kandi biragoye kwemeza ireme ryibitotsi, bizagira ingaruka kumirimo yabo ya buri munsi nubuzima bwabo mugihe runaka.Guhitamo kwambara urusaku-guhagarika gutwi biroroshye kandi byoroshye, bituma uhitamo abantu benshi.
Hamwe niterambere ryibikoresho bishya, gutwi kwa PVC impumu na silicone yamatwi byagaragaye kandi byihuse byamamaye kumasoko.Nyuma, byagaragaye ko ibigize PVC birimo ibintu bifite uburozi, bidakwiriye gukora ibicuruzwa byegereye umubiri wumuntu.Kwambara igihe kirekire biroroshye guteza ingaruka mbi kumubiri wumuntu.Gukoresha ibi bikoresho birabujijwe rwose.Amatwi ya silicone aracyakoreshwa ku isoko muri iki gihe.Amatwi yakozwe mubikoresho bya silicone arashobora gukoreshwa inshuro nyinshi kandi akagira ubuzima burebure.Zikoreshwa cyane cyane mubwishingizi bwumurimo wumurimo utumva urusaku kugirango urinde abakozi kumva, cyangwa nkibikoresho bitagira amazi.Ariko, kubera ubworoherane bwabo bubi, kwambara igihe kirekire gutwi bizatera kubyimba no kubabara., ntibikwiriye gukoreshwa ibitotsi.Ibikoresho bya PU byahindutse ibikoresho byingenzi kubakora mu gihugu no hanze kugirango bakore urusakuugutwi.
Abantu bahitamo ibipapuro bisanzwe byoroshye byoroshye bifite uburemere butandukanye bwa molekile, bakongeramo ubwoko bwihariye bwa catalizator hamwe na stabilisateur ya furo, bakabivanga neza ukurikije igipimo runaka, bavanga TDI yashyutswe muri polyeter yoroshye, hanyuma bakabisuka mubibumbano nyuma yo kubyutsa neza.Gusaza bikorwa muburyo bwo kubona polyurethane sponge yo gukoraamatwi arwanya urusaku.
Urusaku-rusiba gutwi bikozwe muri polyurethane ifuro bifite ibyiza byinshi.
Mbere ya byose, kubera ibyiza byayo bigaruka buhoro, birashobora guhuza neza imiyoboro yabatwi kandi bikagira uruhare runini rwo kugabanya urusaku.Urashobora gukora gusa ikizamini cyo kwisubiramo gahoro kumatwi, gukanda cyane, hanyuma ukareba buhoro buhoro ugutwi nyuma yo kurekura.Irashobora kwagurwa no kugarurwa mugihe gito.Kugirango ugere ku ngaruka nziza yo kugabanya urusaku no gutanga umukino wuzuye kubiranga buhoro buhoro, bigomba guhuzwa nuburyo bukwiye bwo kwambara.Kwinjiza gusa gutwi mu gutwi ntibizagabanya ihumure gusa, ariko kandi ntibizatandukanya neza amajwi kubera ko hari icyuho gito.Uburyo bukwiye nugukubita igice cyo hejuru cyamatwi, gukuramo inguni zo mumatwi yo hejuru, hanyuma ugashyiramo ugutwi mumatwi, hanyuma ugakanda kumatwi kugeza igihe yagutse kandi ahuza numuyoboro w ugutwi.Gusa murubu buryo hashobora kugerwaho ingaruka nziza yo kugabanya urusaku.
Icya kabiri, ugereranije na silicone, amatwi yakozwe muri sponge ya polyurethane afite ubworoherane no guhumeka neza, kandi byoroshye kwambara.Birakwiriye gusinzira amatwi yo gukoresha igihe kirekire.
Icya gatatu, polyurethane sponges ifite umutekano kuyikoresha, itagira ingaruka muburyo butaziguye numubiri wumuntu, kandi ifite akaga gake.Indi ngingo ugomba kwitondera ni uko imiterere yubuso bwamatwi izaba itandukanye bitewe nuburyo butandukanye bwibigize ibintu hamwe nibibazo bitunganijwe, kandi ugutwi kwiziritse ku gukoraho birashoboka ko kwizirika ku ruhu.Fata ugutwi kwi matwi hamwe hanyuma uyatandukane mugihe gito gishoboka.
Kugira ngo wirinde ingaruka z’urusaku, nuburyo bworoshye kandi bworoshye bwo guhitamo amatwi yumwuga kandi yizewe arwanya urusaku.Ni ngombwa cyane guhitamo ibikoresho byo gukora ugutwi.Binyuze mu kugereranya hejuru, ugutwi kwakozwe muri sponge ya polyurethane bifite imiterere myiza yo gusubira inyuma buhoro buhoro, uburyo bwiza bwo guhumeka neza no koroshya umutekano, umutekano muke, birashobora kugabanya urusaku neza, kandi ni amahitamo meza nko kurwanya urusaku.
