Ibisobanuro
Tributyl citrate (TBC) ni plastiki nziza yangiza ibidukikije hamwe namavuta. 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 n'ibicuruzwa by'ubuvuzi n'ubuzima mu Burayi no muri Amerika ndetse no mu bindi bihugu, ndetse n'ibikinisho byoroheje by'abana, imiti, ibikomoka ku buvuzi, uburyohe n'impumuro nziza, gukora amavuta yo kwisiga n'inganda. Irashobora guha ibicuruzwa kurwanya ubukonje bwiza, kurwanya amazi no kurwanya indwara. Nyuma yo guhindurwamo plastiki niki gicuruzwa, resin yerekana neza neza nubushyuhe bwo hasi yubushyuhe 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 nibicuruzwa afite ibintu byiza byo gusiga.
Ibikoresho bya Shimi
Amazi adafite amavuta afite impumuro nke. Kudashonga mumazi, gushonga muri methanol, acetone, karubone tetrachloride, acide glacial acetic acide, amavuta ya castor, amavuta yubutare nandi mashanyarazi.
