Ludox used in the present invention is the glue that the silicon dioxide colloid particulate of 10nm~20nm uniformly diffuses to form in water
Liquid solution, there is sizable specific surface area, has fairly good permeability, and the permeable place of water can be permeated when it, have
Certain viscosity.During Ludox moisture evaporation, colloidal particle is securely attached to body surface, and forming silica between particle combines,
With certain caking property, can not only be formed with specific surface area is big and the gel of uniform pore, but also can dispersed powder.The present invention
Dispersant and bonding i.e. by the use of its good permeability, caking property, film forming, dispersiveness and adsorptivity as molecular sieve powder
Agent.
Molecular sieve powder and Ludox solid-liquid ratio are extremely important during present invention grinding.Ludox content is low, and viscosity is small, glues
Attached force difference, the molecular sieve amount being adhered on base material is few, influences absorption property；Ludox content is high, system viscosity increase, molecular sieve
Disperse in Ludox uneven.In addition, as grinding carries out, system viscosity can gradually increase, and excessive Ludox is easy to cause
Pulp gel.Molecular sieve content is low, and the quantity of sorbent for causing to be adhered on base material is few, and adsorption efficiency is low；And molecular sieve content is high,
Stronger bonding force is needed, and makes substrate deformation, dry linting phenomenon also easily occurs.And excessive molecular sieve is deposited on base material not
It is easily scattered, mass-transfer efficiency can be caused to reduce.So molecular sieve quality fraction about 15%~45%, is advisable with 20%~30%.
Liquid-phase system used in the present invention is Ludox, sensitive to surrounding environment, during grinding material in machine cavity with grinding
Grinding media high velocity impact, high-speed circulating, produces substantial amounts of heat, necessarily causes the lifting suddenly of Ludox temperature, or even can cause
Material gel, this is very unfavorable to subsequent operation.As grinding carries out, material is tapered, and viscosity can increase therewith, heat
The accumulation of amount easily causes material gel plus the lifting of system viscosity, or even blocks machine, it more difficult in progress subsequent operation.Institute
With the present invention uses air-cooled water cooling machine persistently to provide cooling circulating water for sand mill process of lapping.Ensure material drop temperature
Between 15 DEG C~25 DEG C, assist process of lapping to produce heat and scatter and disappear in time, prevent material gelation.
