Tsananguro
Tributyl Citrate (TBC) iri yakanaka yemamiriro ezvinhu epamoyo yeplasticzer uye lubricant. Haisi yehupfu, kudoma, isina ruvara uye yakajeka oiri mvura pamhepo tembiricha. Pfungwa yekubika ndeye 170 ° C (133.3pa), uye iyo Flash Pfungwa (Yakavhurika kapu) ndeye 185 ° C. Nyura mune yakawanda organic sols. Iyo ine yakaderera kusanyunyuta, kuenderana kwakanaka nemahara, uye nekukwira kwepamusoro pekushanda kwakanyanya. Inotenderwa kushandiswa pakudya kwekudya uye nezvekurapa uye hutano nezvigadzirwa muEurope uye nedzimwe nyika dzakapfava, uye zvigadzirwa zvekurapa, zvinonhuwira uye zvinyoronyoro uye mamwe maindasitiri. Inogona kupa zvigadzirwa nekudzikiswa kwakanaka kupesana, kuramba kwemvura uye kudzikisira. Mushure mekunge chigadzirwa ichi, iyo resin inoratidzira pachena zvakanaka Mafuta eLubricating akagadzirira neichi chigadzirwa ane yakanaka lubricating zvivakwa.
Zvemakemikari zvivakwa
Isina ruvara isairi inonamira nekunhuhwirira zvishoma. Insoluble mumvura, soluble in methanol, acetone, carbon tetrachloride, glacial acetic acid, castor oiri, mineral oiri uye mamwe organic sol sol.
Application
-Sakaita segasi chromatography fixative, kusimudzira mumiririri wePurasitiki, remoa remoever uye solvent ye nitrocellose;
- Plasticzez yePolyvinyl chloride, polyethylene copolymer uye cellulose resin, isiri-ine muchetura papasi;
-Kutora kwePocal PVC Granulation, kugadzira chikafu chekudya, zvevana zvakapfava, zvigadzirwa zvekurapa, mapurasitiki ePolyvinyl chloride, vinyl chlolmers, uye cellulose resins.
