Being possible not only to realize Automated condtrol, meanwhile, equipment therefor and simple in construction, operation and maintenance is convenient, and manufacturing cost is more automatically controlled
Device is much lower, and practicality is stronger；
2, the resistance to erosion layer of the present invention uses special compound polyurethane material, is uniformly coated with by the compound polyurethane material of the present invention
Applying after the inwall of conveyance conduit, first mortar produces impact wear to coating, and the polyurethane adhesive in coating is the most bonding
Living silica dioxide granule, adhesive strength is high, and silica dioxide granule difficult drop-off, when polyurethane adhesive is further worn out brokenly
Split when even peeling off, owing to silica dioxide granule hardness is far above polyurethane hardness, polyurethane-base know from experience worn and torn by selectivity and
Make silica dioxide granule gradually show especially, as the silica dioxide granule of high-abrasive material, be highly resistant to sand grains wedge angle in mortar
Cutting and ditch dug with a plow effect, stop coating to be further worn out, and the silica dioxide granule shown especially forms one layer of heavily fortified point at coating surface
The most wear-resisting silicon dioxide layer, and then make coating have outstanding flushing resistance, substantially increase the wearability of conveyance conduit
Can, meanwhile, the mode using coating is more much lower than the mode input cost selecting antifriction metal (AFM), efficiently solves conveying pipe
The problem that road is the most wear-resisting；
3, the conveyance conduit of the present invention, strong adaptability, only need to reequip existing conveyance conduit, the conveying pipe of coating resistance to erosion layer
Road, its wearability is greatly improved, and the use cycle significantly extends, and has saved material cost and maintenance cost for enterprise, is worth big rule
Mould popularization and application.
