(1) Compar\u00e9 \u00e0 l'\u00e9ther de cellulose, l'\u00e9ther de guar est plus soluble dans l'eau. Les performances de l'\u00e9ther de guar pH n'ont pratiquement pas \u00e9t\u00e9 affect\u00e9es.
\n(2) Dans des conditions de faible viscosit\u00e9 et de faible dosage, la gomme de guar peut remplacer l'\u00e9ther de cellulose dans la m\u00eame quantit\u00e9 et a une r\u00e9tention d'eau similaire. Cependant, la consistance, la r\u00e9sistance \u00e0 l'affaissement et la thixotropie sont nettement am\u00e9lior\u00e9es.
\n(3) Dans des conditions de viscosit\u00e9 \u00e9lev\u00e9e et de dosage important, la gomme de guar ne peut pas remplacer l'\u00e9ther de cellulose, et l'utilisation mixte des deux permet d'obtenir d'excellentes performances.
\n(4) L'application de la gomme guar dans le mortier \u00e0 base de gypse peut r\u00e9duire consid\u00e9rablement l'adh\u00e9rence pendant la construction et rendre la construction plus lisse. Aucun effet n\u00e9gatif sur le temps de prise et la r\u00e9sistance du mortier de gypse.
\n(5) Lorsque la gomme guar est utilis\u00e9e dans le mortier de ma\u00e7onnerie et de pl\u00e2trage \u00e0 base de ciment, elle peut remplacer l'\u00e9ther de cellulose en quantit\u00e9 \u00e9gale et conf\u00e9rer au mortier une meilleure r\u00e9sistance \u00e0 l'affaissement, une meilleure thixotropie et une meilleure fluidit\u00e9 de construction.
\n(6) La gomme de guar peut \u00e9galement \u00eatre utilis\u00e9e dans les adh\u00e9sifs pour carreaux de c\u00e9ramique, les agents autonivelants pour sols, les mastics r\u00e9sistants \u00e0 l'eau, le mortier polym\u00e8re pour l'isolation des murs et d'autres produits.
\n(7) Le prix de la gomme de guar \u00e9tant nettement inf\u00e9rieur \u00e0 celui de l'\u00e9ther de cellulose, l'utilisation de la gomme de guar dans le mortier r\u00e9duira consid\u00e9rablement le co\u00fbt des formulations de produits.<\/p>\n
