Kufotokozera
Tributyl citrate (TBC) ndi pulasitiki wabwino wokonda zachilengedwe komanso wothira mafuta.Ndiwopanda poizoni, wofewa, wopanda mtundu komanso wowoneka bwino wamafuta amadzimadzi otentha kutentha.Malo otentha ndi 170 ° C (133.3Pa), ndipo kung'anima (chikho chotsegula) 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, oonetsera ndi onunkhira, zodzoladzola kupanga ndi mafakitale ena.Imatha kupatsa zinthu zotetezedwa bwino kuzizira, 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 muzojambula zosiyanasiyana, kukhazikika 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 organic.
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 zoyika chakudya, zoseweretsa zofewa za ana, mankhwala azachipatala, mapulasitiki a polyvinyl chloride, vinyl chloride copolymers, ndi ma cellulose resins.
