10%V is pressed after liquid mist1The volumetric rate of/min is passed through until mixed solution PH6-6.5, is opened after dripping flower bulb aqueous alkali
Begin to heat up, start to keep the temperature when until being warming up to 80 DEG C -90 DEG C, be kept stirring rate and temperature 40min-50min, then filter out and returns
Liquid is received, Solid content is retained, which is required Special grinding material.
2. a kind of dedicated micro-crystalline ceramic abrasive material of machine tool industry, it is characterised in that: the Special grinding material is made of two parts, and first
It is divided into 30 parts -35 parts of alumina powder, 2 parts -2.5 parts of lanthanum nitrate hexahydrate, 3 parts -5 parts of the hydroxyapatite crystallite sintering in shuttle kiln
Made of 34 parts -42 parts of micro-crystalline ceramic；Second part is that three component polymerization reactions obtain, and wherein component A is by weight
45 parts -50 parts of vinyl ethylenically unsaturated monomer, 0.1 part -0.2 part of phosphorus bidentate ligand, acute 15 parts -18 parts of sawdust powder, glass
2 parts -3 parts of glass micro mist, the mixture that 8 parts -10 parts of withered stalk powder is raw material；Component B is with acrylate-based olefinic insatiable hunger
With 26 parts -28 parts of monomer, the second component that 0.2 part -0.3 part of collagen activation enzyme aqua is raw material；Component C is containing Solute mass point
The flower bulb aqueous alkali of number 10%, the component relationship of second part are with acute sawdust, glass micro mist, withered stalk in collagen activation
Glass micro mist of the indissoluble cellulosic and adhesive curing obtained under enzyme effect in cellulosic is core, and micro silicic acid gel is glue
The polymer of viscous medium, vinyl ethylenically unsaturated monomer and acrylate-based ethylenically unsaturated monomer is the microcapsules knot of formwork
Structure.
