полиакриламид порошок / гель

Hydroxypropyl methyl cellulose(HPMC) is a material widely used as thickener,emulsifier,film former,binder,dispersion agent,protective colloid,etc.In building materials,paint,paper,printing,synthetic resin,ceramics,textiles,agriculture and other industries widely used as thickener,emulsifier,film former,binder,dispersion agent,protective colloid,etc...and we suupply of agood quality and low price for a long-term,welcome new and old come negotiate clients. Especial Character Dissolve in the water and the part organic solvent: Hydroxypropyl methyl cellulose(hpmc) can dissolve in cool water.Its concentration depends on viscosity.The solubility changes along with its viscosity.If the viscosity is lower,the solubility can be bigger.Some product may dissolve in the dual organic solvent and the organic solvent-water system. Salt-tolerance:Harvecell is non-ionic cellulose ether is not electrolyte,Hydroxypropylmethy cellulose tends to be steady in metallic salt or organic electrolyte aqueous solution.But if the content of electrolyte is continued to increase,it can gelate and percipitate. Surface-active:The aqueous solution of the product is surface-active,so it can be used for colloid protecing agent,emulsified and dispersing agent. Hpt gelatin:When the Harvecell water solution is heated to the certain temperature,it will become opaque and form the precipitation.But when solution becomes cool,it restores to the original solution.The certain temperature at which gelatin and the precipitation form is mainly decided by their lubricant,the deflocculated,protective colloid,emulsifier and so on. Mold resistance:For it has the quite good anti-mildew ability,it has good stability after long-term storage. PH value stability:The Harvecell aqueous solution couldn't be influenced by acid and alkai.It is steady when its PH value of aqueous solutions is between 3.0-11.0. Water preserving capability:Compared with other polymer aqueous solution,the Harvecell's high concentration aqueous solution has special viscoelasticity,this characteristic can improve the shape of the extrusion porcelain and so on. Water preserving capability:Its aqueous solution is hydrophilic and high viscous,so it is effective at water retention. Other characteristic:Thickening,film forming bond,tubrification,the deflocculating,protecting colloid,emulsifier and so on. .
