Putty powder is a surface leveling powder for surface prtreatment before paint construction, the main purpose is to fill the pores on the construction surface and rectify the curve deviation of construction surface, in order to obtain uniform, smooth finish lay.
Putty powder is generally composed of base material, filler, water and additives and other components. The base material (also known as binder) is the most critical component of putty, mainly bonding, most commonly used binder is cement and organic polymers; filler mainly from the role of filling, commonly used calcium carbonate, talc and quartz sand and so on. Therefore, the composition of putty's grinding fineness, the degree of uniformity will be directly related to putty powder can achieve uniform, smooth finish effect.
The commonly used putty powder production equipment is:
MTW European type trapezium mill
: it uses bevel gear overall transmission, internal thin oil lubrication system, curved duct and many other patented technologies. It has the advantages of stable performance, high grinding efficiency, low energy consumption, finished product particle size controllable (0.2-0.033mm / 80-425 mesh). The model MTW215T European type grinding mill's capacity is up to 50t/h to meet the large-scale putty powder grinding requirements.
