Tributyl citrate (TBC) yog ib qho zoo ib puag ncig zoo plasticizer thiab lubricant.Nws yog non-toxic, fruity, colorless thiab pob tshab oily kua nyob rau hauv chav tsev kub.Kub taw tes yog 170 ° C (133.3Pa), thiab lub teeb nyem (qhib khob) yog 185 ° C.Soluble nyob rau hauv feem ntau cov organic solvents.Nws muaj tsawg volatility, zoo compatibility nrog resins, thiab siab plasticizing efficiency.Nws raug tso cai siv rau hauv cov khoom ntim khoom noj thiab cov khoom siv kho mob thiab kev noj qab haus huv hauv Tebchaws Europe thiab Tebchaws Meskas thiab lwm lub tebchaws, nrog rau cov menyuam yaus cov khoom ua si mos, tshuaj, khoom siv kho mob, tsw thiab tshuaj tsw qab, kev tsim tshuaj pleev ib ce thiab lwm yam lag luam.Nws tuaj yeem muab cov khoom lag luam nrog kev ua haujlwm txias txias, dej tsis kam thiab mildew tsis kam.Tom qab plasticized los ntawm cov khoom no, cov resin pom zoo transparency thiab qis-kub dabtsi yog khoov kev ua tau zoo, thiab muaj tsawg volatility thiab tsis tshua muaj extraction nyob rau hauv txawv xov xwm, zoo thermal stability, thiab tsis hloov xim thaum rhuab.Cov roj lubricating npaj nrog cov khoom no muaj cov khoom zoo lubricating.
Xim oily kua nrog me ntsis tsw.Insoluble hauv dej, soluble hauv methanol, acetone, carbon tetrachloride, glacial acetic acid, castor roj, ntxhia roj thiab lwm yam organic solvents.
-Siv raws li cov roj chromatography fixative, ib tug toughening neeg sawv cev rau yas, ua npuas ncauj tshem tawm thiab ib tug hnyav rau nitrocellulose;
- Plasticizer rau polyvinyl chloride, polyethylene copolymer thiab cellulose resin, non-toxic plasticizer;
-Siv rau cov tsis muaj tshuaj lom PVC granulation, ua cov khoom ntim khoom noj, cov khoom ua si me nyuam mos, cov khoom siv kho mob, cov yas yas rau polyvinyl chloride, vinyl chloride copolymer, thiab cellulose resins.
