Clock；
4) dry mash, mixed imports finished product homogenizing storehouse；
5), electronic measurement is packed automatically；
6), finished product warehouse-in.
The operation principle of the present invention and process prescription:
1, selecting superfine cement and slag micropowder as Binder Materials, its total surface area is much larger than the summary table of aggregate
Area, studying and putting into practice the most fully proves, " total surface area of adhesive material is more than the total surface area of aggregate,
I.e. can be made into oil-proof concrete ", this is the basis that resistance to oil sand slurry stops all kinds of fat migration.And, slag is micro-
Powder also has the function of filling fine pore and capillary tube concurrently.
2, the introducing of compounding compacting agent, introduces alunite [aluminum potassium sulfate KAl (SO in this resistance to oil sand slurry4)2]、
Formation entringite (C is reacted with hydrolysis product of cement3A·3CaSO4·32H2O), wet mortar is by crystallographic expansion
Stress effect, on the one hand compensate for shrinking, eliminates crackle and make again Behavior of Hardened Cement Paste more they tend to densification.Research and practice
Prove: the pore of ferric hydroxide gel blocking hydration and hardening body, it is possible to stop the infiltration of each quasi-grease；Add
Various gels, are more than 280 μ apertures in hydrated calcium silicate gel (C-S-H) further fill concrete
Harmful hole, mortar watertightness, impermeability are improved.
3, the interpolation of redispersable latex powder, hardened mortar pore structure forms the continuous thin film closed, and (what is called has
Machine inorganic crosslinking structure) so that the corrosion resistance of mortar hydration and hardening body is greatly strengthened, and mixes with basic unit
The cohesive force of solidifying soil strengthens at double, improves corrosion resistance and the durability of resistance to oil sand slurry.
4, early strength agent calcium formate makes this hydration and hardening of resistance to oil sand slurry process accelerate.
5, this resistance to oil sand slurry selects quartziferous graded sand as aggregate, meets closestpacking principle so that
Hydration and hardening body is more densely cross-linked.
6, thixotropic agent and water-retaining admixture (HPMC) so that this resistance to oil sand slurry workability and cracking resistance
It is greatly improved.
7, electronic computer controls lower factorial praluction, and proportioning is precisely consistent, and quality is the neatest.
The medicine have the advantages that compared with existing like product and technology, this resistance to oil sand slurry resists each quasi-grease
Infiltration, has good workability, and strong with basic unit cohesive force, hollowing does not ftractures.This product adds 20%～30%
It is dried 5～35mm closely knit grating stones, can be made into oil-proof concrete.It addition, have the further advantage that
1, this resistance to oil sand slurry have employed compounding compacting agent, and anti-all kinds of fat migration performances are remarkable.
2, this resistance to oil sand slurry have employed Germany's import redispersable latex powderModification,
Organic material and the cross-linked structure of inorganic material is formed after mortar hardening, the most more densely cross-linked, more impervious.
3, this resistance to oil sand slurry is high with basic unit cohesive force, and workability is excellent, not hollowing, do not ftracture.
4, this resistance to oil sand slurry interpolation 20%～30% is dried closely knit 5～35mm grating stone, can make
Become oil-proof concrete.The premixing large-scale production of this resistance to oil sand slurry factory, product quality is the most stable.
