Kufotokozera
Tributyl citrate (TBC) ndi pulasitiki wabwino wosamalira zachilengedwe komanso mafuta. Ndiwopanda poizoni, wofewa, wopanda mtundu komanso wowoneka bwino wamafuta amadzimadzi otentha kutentha. Kuwirako ndi 170°C (133.3Pa), ndipo kung’anima (chikho chotseguka) ndi 185°C. Zosungunuka m'ma organic solvents. Ili ndi kusakhazikika kochepa, kumagwirizana bwino ndi utomoni, komanso kugwiritsa ntchito bwino kwa pulasitiki. Amaloledwa kugwiritsidwa ntchito pakupanga chakudya ndi mankhwala ndi mankhwala ku Ulaya ndi United States ndi mayiko ena, komanso zoseweretsa zofewa ana, mankhwala, mankhwala mankhwala, zokometsera ndi zonunkhira, zodzoladzola kupanga ndi mafakitale ena. Imatha kupatsa mankhwala ndi kukana kuzizira bwino, kukana madzi komanso kukana mildew. Pambuyo popangidwa ndi pulasitiki ndi mankhwalawa, utomoniwo umasonyeza kuwonekera bwino komanso kutsika kwa kutentha kwapakati, ndipo imakhala ndi kusinthasintha kochepa komanso kutsika kochepa muzofalitsa zosiyanasiyana, kukhazikika kwabwino kwa kutentha, ndipo sikumasintha mtundu ukatenthedwa. Mafuta opaka mafuta okonzedwa ndi mankhwalawa ali ndi mafuta abwino.
Chemical Properties
Mafuta amadzimadzi opanda mtundu komanso onunkhira pang'ono. Insoluble m'madzi, sungunuka mu methanol, acetone, carbon tetrachloride, glacial acetic acid, mafuta a castor, mafuta amchere ndi zosungunulira zina.
Kugwiritsa ntchito
- Ntchito ngati gasi chromatography fixative, toughening wothandizira mapulasitiki, chochotsa thovu ndi zosungunulira kwa nitrocellulose;
- Pulasitiki wa polyvinyl chloride, polyethylene copolymer ndi cellulose resin, plasticizer yopanda poizoni;
- Amagwiritsidwa ntchito popanga granulation yopanda poizoni ya PVC, kupanga zida zoyikamo chakudya, zoseweretsa zofewa za ana, mankhwala azachipatala, mapulasitiki a polyvinyl chloride, vinyl chloride copolymers, ndi ma cellulose resins.
