Epoxidized Soybean Oil (ESBO): Kev Pom Zoo
Epoxidized Soybean Oil yog dab tsi?
Epoxidized Soybean Oil (ESO lossis ESBO) yog ib qho khoom noj khoom haus zoo ib puag ncig uas tau los ntawm cov taum roj los ntawm cov txheej txheem epoxidation. Nws feem ntau muaj unsaturated glycerol esters nrog cov lej ntawm cov xim, phospholipids, thiab lwm yam impurities. Paub txog nws txoj kev sib raug zoo, kev ruaj ntseg, thiab cov khoom siv hauv eco, ESBO tau siv dav hauv kev lag luam.
Qhov sib txawv ntawm ESBO thiab Soybean Roj
Kev siv
Soybean Roj: Cov roj siv tau siv rau kev ua noj thiab ua zaub mov.
ESBO: Muaj tshuaj siv los ua plasticizer, stabilizer, thiab lwm yam kev siv hauv kev lag luam. Nws yogtsis noj.
Kev ua haujlwm
Soybean roj tau ua tiav tsawg kawg rau kev siv zaub mov.
ESBO yog tsim los ntawm cov tshuaj tiv thaiv, xws li epoxidation, kom ua tiav nws lub cev tshwj xeeb thiab tshuaj lom neeg.
Physical and Chemical Properties of ESBO
Qhov tshwm sim: Lub teeb rau tsaus daj kua nplaum
Qhov ntom: ~0.985 g/cm³ (25 degree)
Txias Point: -10 mus rau 5 degree
Flash Point: 280-310 degree
Solubility: Soluble nyob rau hauv feem ntau cov organic solvents, insoluble nyob rau hauv dej
ToxicityLD50> 22.5 mL / kg (qhov ncauj, nas), cais raws li kev xyaum tsis muaj tshuaj lom
Cov qauv molecular ntawm ESBO nta cov epoxy active pawg uas tuaj yeem hnov mob nrog amines, hydroxyl, thiab lwm pab pawg ua haujlwm los tsim cov polymers sib txawv nrog cov khoom tshwj xeeb.
Cov txheej txheem tsim khoom
Kev tsim khoom ntawm ESBO suav nrog epoxidation ntawm cov roj taum pauv. Cov txheej txheem muaj xws li:
Txoj kev Peroxidation
Cov tshuaj tiv thaiv ntawm cov roj taum pauv thiab peroxyacids (xws li formic lossis acetic acid nrog hydrogen peroxide) ua rau ESBO. Txoj kev no yog ncaj nraim thiab tso cai rau automation.
Ion-Exchange Resin Catalysis
Siv ion-exchange resins ua ib qho catalyst rau hnyav-dawb epoxidation. Nws yog ib puag ncig tus phooj ywg tab sis yuav tsum tau siv sijhawm ntev dua.
Phase-Transfer Catalysis
Siv cov theem-hloov catalysts los txhim kho cov txheej txheem epoxidation, txo cov khoom los ntawm cov khoom thiab txhim kho cov khoom zoo.
Cov ntawv thov tseem ceeb ntawm ESBO
1. Plasticizer thiab Stabilizer rau PVC
ESBO yog siv dav hauv kev ua cov khoom siv PVC:
Plasticization: Txhim kho qhov yooj yim thiab ntws cov khoom ntawm PVC.
Stabilization: Absorbs HCl tso tawm thaum lub sij hawm PVC degradation, prolonging khoom lifespan.
Cov ntawv thov uas muaj xws li:
Zaj duab xis, cov ntawv, thiab cov kav dej
Synthetic tawv thiab cov ntaub ntawv cable
Lub tub yees gaskets, flooring, thiab wallpapers
2. Eco-Friendly Plasticizer
Ua raws li FDA, RoHS, thiab REACH cov cai, ESBO yog ib qho kev lees paub tsis muaj tshuaj lom thiab eco-friendly plasticizer rau:
Khoom noj khoom haus thiab tshuaj ntim khoom
Cov menyuam yaus cov khoom ua si thiab cov khoom siv kho kom zoo nkauj
Pob tshab fwj thiab ntim
3. Kev hloov kho rau cov txheej txheem thiab cov nplaum nplaum
ESBO muaj nuj nqis hauv cov txheej thiab cov nplaum rau nws cov molecular yooj thiab viscosity tsawg. Cov ntawv thov suav nrog:
Acrylate epoxy systems
Cationic UV-curable txheej
Low-VOC alkyd resin coatings, qhov twg ESBO ua raws li reactive diluent
Xaus
Epoxidized Soybean Roj sawv tawm rau nws qhov tshwj xeeb thermal thiab UV stability, tsis tshua muaj kev tsiv teb tsaws, thiab eco-friendly yam ntxwv. Raws li lub hnub qub khoom nyob rau hauv PVC ua thiab ntsuab plasticizer daim ntaub ntawv, ESBO tsis tsuas yog txo cov nqi tsim khoom tab sis kuj txhim khu kev zoo thiab kev ua tau zoo ntawm cov khoom kawg. Nws ua piv txwv txog kev sib xyaw ntawm tshuaj lom neeg tshiab thiab kev txhim kho kom ruaj khov hauv kev lag luam niaj hnub no.
