\u4e00\uff0ePropri\u00e9t\u00e9 du produit<\/h3>\n

L'\u00e9ther monom\u00e9thylique du poly\u00e9thyl\u00e8ne glycol (MPEG) est un agent de surface non ionique. Il se pr\u00e9sente sous la forme d'un liquide incolore \u00e0 jaune p\u00e2le ou d'un solide p\u00e2teux. Ce produit pr\u00e9sente une excellente solubilit\u00e9 dans l'eau et une grande stabilit\u00e9 chimique. Les groupes m\u00e9thoxy et hydroxyle aux extr\u00e9mit\u00e9s mol\u00e9culaires lui conf\u00e8rent une excellente r\u00e9activit\u00e9. Le MPEG est peu toxique et non irritant, r\u00e9pondant aux normes de s\u00e9curit\u00e9 des industries pharmaceutiques et cosm\u00e9tiques. Il poss\u00e8de \u00e9galement de multiples caract\u00e9ristiques fonctionnelles telles que le mouillage, l'\u00e9mulsification et la dispersion. En fonction des sp\u00e9cifications de poids mol\u00e9culaire, il peut \u00eatre largement utilis\u00e9 dans des domaines tels que les vecteurs de m\u00e9dicaments, les additifs de rev\u00eatement et les auxiliaires textiles, r\u00e9pondant aux besoins de diverses applications allant des solvants aux \u00e9paississants.<\/p>\n

\u4e09\uff0eApplication du champ d'application et utilisation<\/h3>\n

Il est utilis\u00e9 dans l'industrie des mat\u00e9riaux de construction comme mati\u00e8re premi\u00e8re pour r\u00e9duire la teneur en eau du ciment et am\u00e9liorer ses propri\u00e9t\u00e9s. Le r\u00e9ducteur d'eau de type polycarboxylique \u00e0 haut rendement synth\u00e9tis\u00e9 avec cette mati\u00e8re premi\u00e8re a une forte capacit\u00e9 \u00e0 disperser les particules de ciment et \u00e0 maintenir la dispersion. Par cons\u00e9quent, le produit pr\u00e9sente les avantages suivants : faible dosage, taux de r\u00e9duction d'eau \u00e9lev\u00e9, bon effet de renforcement, bonne durabilit\u00e9, r\u00e9sistance \u00e0 la corrosion des barres d'armature et respect de l'environnement. Il peut \u00eatre utilis\u00e9 dans les b\u00e9tons commerciaux \u00e0 haute performance et \u00e0 haute r\u00e9sistance (sup\u00e9rieure \u00e0 C60) pour le m\u00e9lange sur site et le transport sur de longues distances.<\/p>\n

Soluble dans l'eau, l'\u00e9thanol et les solvants organiques. Faible pression de vapeur, stable \u00e0 la chaleur. Utilis\u00e9 comme \u00e9paississant et lubrifiant dans l'industrie de l'impression et de la teinture des textiles ainsi que dans l'industrie cosm\u00e9tique.<\/p>\n
