Carbomer 940 ua
Carbomer 940 ua
Carbopol 940, tseem hu ua Carbomer los yog Carboxypoly-methylene yog lub npe generic rau hluavtaws siab molecular hnyav polymers ntawm acrylic acid siv ua thickening, dispersing, ncua thiab emulsifying cov neeg ua hauj nyob rau hauv kws tshuaj thiab tshuaj pleev ib ce.Lawv yuav yog homopolymers ntawm acrylic acid, crosslinked nrog ib tug allyl ether pentaerythritol, allyl ether ntawm sucrose los yog allyl ether ntawm propylene.Carbomers pom nyob rau hauv kev ua lag luam raws li cov hmoov dawb thiab fluffy.Lawv muaj peev xwm nqus tau, khaws dej thiab o mus rau ntau zaus lawv cov ntim qub.Carbomers codes (910, 934, 940, 941 thiab 934P) yog qhov qhia txog qhov hnyav molecular thiab cov khoom tshwj xeeb ntawm cov polymer.
Cov khoom no yog acrylic bonded allyl sucrose los yog pentaerythritol allyl ether polymer.Muab xam rau ntawm cov khoom qhuav, suav nrog pawg carboxylic acid (-cooh) pawg - yuav tsum yog 56. 0 % ~ 68. 0 %.
