Tsanangudzo
Tributyl citrate (TBC) ipurasitiki yakanaka ine hushamwari kwezvakatipoteredza uye lubricant.Iyo isiri-chepfu, ine muchero, isina ruvara uye yakajeka ine mafuta mvura patembiricha yekamuri.Panofashaira i170°C (133.3Pa), uye panopenya (kapu yakavhurika) i185°C.Soluble mune zvakawanda organic solvents.Iyo ine yakaderera volatility, yakanaka kuenderana neresin, uye yakakwira plasticizing kunyatsoita.Inotenderwa kushandiswa mukugadzira chikafu uye zvigadzirwa zvekurapa uye zvehutano muEurope neUnited States nedzimwe nyika, pamwe chete nematoyi evana akapfava, mishonga yemishonga, zvigadzirwa zvekurapa, zvinonhuhwirira uye zvinonhuhwirira, kugadzira zvizorwa uye mamwe maindasitiri.Inogona kupa zvigadzirwa zvine kunaka kutonhora kupikisa, kusamira kwemvura uye huturu.Mushure mekugadzirwa kwepurasitiki nechigadzirwa ichi, resin inotaridza kujeka uye kudzika-tembiricha yekukotama kuita, uye ine yakaderera kunyungudika uye yakaderera kudhirowa mune akasiyana midhiya, yakanaka kugadzikana kwekupisa, uye haichinji ruvara kana yapiswa.Mafuta ekuzora anogadzirwa nechigadzirwa ichi ane zvinhu zvakanaka zvekuzora.
Chemical Properties
Mvura ine mafuta isina ruvara uye inonhuwa zvishoma.Isingasviki mumvura, soluble mu methanol, acetone, carbon tetrachloride, glacial acetic acid, castor mafuta, mineral oil uye mamwe organic solvents.
Application
