Ibisobanuro
Tributyl citrate (TBC) ni plastike nziza kandi yangiza ibidukikije.Ntabwo ari uburozi, imbuto, ibara ritagira ibara kandi rifite amavuta meza mubushyuhe bwicyumba.Ahantu ho gutekera ni 170 ° C (133.3Pa), naho flash point (igikombe gifunguye) ni 185 ° C.Gukemuka mumashanyarazi menshi.Ifite ihindagurika rito, ihuza neza na resin, hamwe na plastike ikora neza.Biremewe gukoreshwa mu gupakira ibiryo no mu buvuzi n’ubuzima mu Burayi no muri Amerika ndetse no mu bindi bihugu, ndetse n’ibikinisho byoroheje by’abana, imiti y’imiti, ibikomoka ku buvuzi, uburyohe n'impumuro nziza, gukora amavuta yo kwisiga n'inganda.Irashobora gutanga ibicuruzwa hamwe no kurwanya ubukonje bwiza, kurwanya amazi no kurwanya indwara.Nyuma yo guhindurwamo plastiki niki gicuruzwa, resin yerekana neza neza no gukora ubushyuhe buke bwo hasi, kandi ifite ihindagurika rito hamwe no gukuramo bike mubitangazamakuru bitandukanye, ubushyuhe bwiza bwumuriro, kandi ntabwo bihindura ibara iyo bishyushye.Amavuta yo gusiga yateguwe niki gicuruzwa afite ibyiza byo gusiga.
Ibikoresho bya Shimi
Amavuta adafite ibara afite impumuro nke.Kudashonga mumazi, gushonga muri methanol, acetone, karubone tetrachloride, acide glacial acetike, amavuta ya castor, amavuta yubumara nibindi bimera.
Gusaba
