The preferred plan of the present invention wherein weight proportion of each raw material is:
55 parts of 37 parts of quartz sands of ordinary Portland cement
3 parts in 1.7 parts of flyash of aluminosulfate cement
0.4 part in 0.7 part of dihydrate gypsum powder of latex powder
0.4 part of 2 parts of water reducer of silicon dioxide powder
0.16 part of the polypropene staple of 0.15 part of length 1-3mm of ether of cellulose.
Described water reducer is a naphthalene sulfonic acidformaldehyde condensation product.The length of described polypropene staple is 1-3mm.The above-mentioned material that provides has been realized purpose of the present invention.
The present invention has following advantage:
1, the present invention is applied widely, easy construction, swift to operate, be easy to grasp, can be easily and the protection configurations of different shape.Can be widely used in the liner wearing-resistant layer of sluice in metallurgy, the mine system, ore deposit groove, feed bin etc., the liner wearing-resistant layer in the groove of unloading coal in coal system, fuel-burning power plant, the coke-oven plant, coal hopper, barrel storehouse etc., liner wearing-resistant layers such as the tower silo of system such as cement, chemical industry, hopper, storehouse wall, water conservancy and hydropower, port and pier etc. has the concrete wearing-resistant layer of antiscour, wear-resistant requirement.
Scene of the present invention adds water and stirs and can use; easy construction, swift to operate, construction workability is good, forms certain thickness wearing-resistant layer by manually plastering at protection surface of base such as feed bin or ore deposit grooves; can reach technical requirements through normal and maintenance, result of use is good.And traditional ceramic plate, glass cermaic plate, polyethylene board, nylon sheet, rubber plate and calendering crystallite plate all need be protected on the basis with inorganic or organic binding bonding, and use bolting, and be assembled, needs the professional construction personnel operation; Iron-filing mortar, iron-aggregate concrete need to build with formwork, smear with the steel spatula again, numerous rope trouble of constructing.
2, the invention solves the ultimate compression strength of traditional wear-resistant material low, high temperature resistant and wear resisting property is poor, easy to crack, easily aging, work-ing life is short, easily distribute the high deficiency of toxic gas, not environmental protection and cost.
Technical indicator of the present invention is as follows:
| Project | Unit | Technical indicator |
| Ultimate compression strength | MPa | ≥60 |
| Abrasion loss | kg/m 2 | ≤0.1 |
| Young's modulus | MPa | ≥4.0×10 4 |
| Heat resistance | ℃ | ≤500 |
| With substrate bonding intensity | MPa | ≥1.5 |
| Construction temperature | ℃ | ≥5 |
| Unit weight | kg/m 3 | 2200～2400 |
The present invention compares with traditional iron-filing mortar, iron-aggregate concrete has the resistance to abrasion height, and erosion resistibility is strong, and the bonding strength height between base concrete, the ultimate compression strength height, and wear resistance is good, high-time characteristics.
The present invention compare with traditional ceramic plate, glass cermaic plate and calendering crystallite plate have the construction simple, high efficiency; The workmen is not had any toxic side effect, belong to Green Product, meet the growth requirement of contemporary green building; Overall cost is low, greatly reduces engineering cost, and the high advantage of shock resistance is arranged.And ceramic plate, glass cermaic plate and calendering crystallite plate fragility are big, and impact resistance is poor, are difficult for the protection configurations with different shape.
The present invention compares with traditional nylon sheet, polyethylene board and rubber plate has high temperature resistance, the advantage of good flame resistance.And traditional nylon sheet, polyethylene board and rubber plate belong to organic wear-resistant material, the wearing-resistant layer in the bunker that poor, inflammable, the uncomfortable cooperation sulphur content of resistance to elevated temperatures is high, coal charge storehouse etc.
The present invention compares with stainless steel plate, cost is lower, and shock resistance is good.
3, the present invention also has simple manufacturing process, and water-intake rate is low, and anti-oil oozes, anti-high and low-temp, and overall performance is good, is easy to repair, difficult drop-off, material is easy to get, and is beneficial to the advantage of utilization and extention.
