1.Strength test: gypsum-based hydroxypropyl methyl cellulose has good tensile bonding strength and compressive strength.
2.Sagging resistance test: no sagging in single construction when draped in thick layers, no sagging when draped in more than two times (above 3cm), good plasticity.
3.Wall draping test: draping light, smooth, can be formed at once, the surface is delicate and soft, with brightness.
4.Coating rate test: gypsum-based coating rate refers to the result obtained by measuring the wet weight of the gypsum-based conversion. One ton of gypsum-based products can be applied to a 10mm thick wall area.
5.Water retention rate test: The water retention rate refers to the standard GB/T28627-2012 "Plastering Gypsum", the water retention rate of light weight base layer plaster is greater than or equal to 60%. The gypsum-based hydroxypropyl methyl cellulose has good water retention performance when added at 0.2% and 0.25%.

The production process of hydroxypropyl methylcellulose is mainly a polysaccharide-based ether product produced by alkalinisation and etherification of cotton fibres (domestic). It is not charged itself and does not react with the charged ions in the gelling material, making it stable.The price is a
Hydroxypropyl methyl cellulose is a tasteless, odorless and non-toxic white powder that dissolves in water to form a transparent, viscous liquid. Hydroxypropyl methyl cellulose with adhesion, thickening, emulsification, dispersion, film forming, adsorption, gelling, surface moisture and protective c
