PEG-400 kua CAS NO.25322-68-3
Khoom Description
- PEG-400 tsis muaj tshuaj lom, tsis ua rau khaus, iab me ntsis hauv saj, muaj dej solubility zoo, thiab muaj kev sib raug zoo nrog ntau cov khoom siv organic. Lawv muaj lubricity zoo heev, dispersibility, adhesives thiab softeners thiab yog dav siv nyob rau hauv cov tshuaj pleev ib ce, tshuaj, tshuaj fiber, roj hmab, yas, papermaking, xim, electroplating, tshuaj tua kab, hlau ua thiab zaub mov industries.
- PEG-400 yog soluble nyob rau hauv dej thiab ntau yam organic solvents, tab sis insoluble nyob rau hauv aliphatic hydrocarbons, benzene, glycol, thiab lwm yam yuav tsis hydrolyzed thiab deteriorated. Nws muaj kev ruaj ntseg zoo, lubricity, dej solubility, noo noo tuav, adhesion thiab thermal stability. Yog li ntawd, raws li lubricants, humectants, dispersants, adhesives, excipients, thiab lwm yam, nws yog siv nyob rau hauv cov tshuaj, tshuaj pleev ib ce, roj hmab, yas, chemical fiber, ntawv, xim, electroplating, tshuaj tua kab, hlau ua thiab zaub mov industries. Ntau yam kev siv.
- PEG-400 ruaj khov thiab tsis yooj yim deteriorated. Kev txhaj tshuaj uas muaj PEG muaj kev nyab xeeb thiab ruaj khov thaum kub txog 150 degrees Celsius. Tsis tas li ntawd, nws tuaj yeem sib xyaw nrog qhov hnyav molecular hnyav (PEG), tab sis xya qhov sib xyaw muaj qhov zoo solubility thiab zoo sib xws nrog cov tshuaj.
