Complete Coating Equipment

In a long time, coatings equipment is mark upof disperse machine, sand mill machine and 3-roller machine. That coatingequipment has the different functions for different needing, but they are allhaving the limitations. Such as:

For disperse machine, when producing the middle and high grade coatings, itcould only serve for pre-disperse and could not add up to the requiring crusheffect.

For sand mill machine, it could production continuously, but it is not suitablefor apply in hard disperse materials. When the material is high viscidity, itis hard to process, hard to clean and high reminds.

For 3-roller machine, it is suitable for hard disperse and high visciditymaterials, but its open type operation brings to bad work circumstance, badsafety and high material lost, it also has disadvantages such as: complexconstruction, hard adjust and low production efficiency.

From the middle nineties of last century, some of the domestic factory appliesthe high-shear emulsification equipment in coatings production which appliesmainly in liquid mix field in overseas to replace those national dispersingmachine, sand mill machine and 3-roller machine. Those factories profess thatit is the once and for ever solution for coatings productions.

However, the following one by one bad market news relapse those factories intotrouble. The main defect of this new machine is: as to high and middle gradecoatings, this high-shear emulsifier could not reach the fine degree thatfactory request at all. As a company who process of 7 items of nationalhigh-shear technology, our company had also been disturb by this trouble. Thefine degree defect is the reason why high-shear emulsifier could not dominatein the world coatings equipments market and could not been recognize by theinternational academe field.

Therefore, almost all the high-shear manufacturer to mill it more by horizontalsand mill machine besides the high-shear emulsifier. This coatings makingmethod puzzled those factories: the fine grade is settle still by thosetraditional sand mill machine, the hard clean, hard color-change and highremains problems are still on, the emulsifiers price is many times than thetraditional disperse machine, how can we call this high-shear coatings makingmethod as the advanced one?

Above all, though the traditional coatings equipment has apply for years, it islimitation still obviously. The high-shear coatings making method is followthe high-shear emulsifier plus sand mill machine method in essential, it alsocould not solute the traditional coating equipments limitation.
