Can bentonite be used as rubber powder?
Fillers mainly play the role of filling, commonly used calcium carbonate, talc and quartz sand. Attention should be paid to the use of filler fineness.Additives include thickeners, water retaining agents, etc.. Thickening agents and water retaining agents play an important role in water conservation, storage and construction. Cellulose is generally usedBentonite in the putty powder can replace 30% base material and 30% filler and 50% additives. Why not add water less bentonite caused by shrinkage cracks.
Base material, also known as binder, is the most important component of putty, mainly from the role of bonding and so on. Putty is the most commonly used cement and organic polymer, organic polymer and emulsion and latex powder. Cement is a binder with good cohesiveness, durability and reasonable cost performance, but its tensile strength and crack resistance are poor. Organic polymers can be modified and toughened to improve the properties of putty.
Putty powder is usually composed of base materials, fillers and additives.
