A metal bonder diamond tool is matched with a grinding material with relatively large granularity to primarily roughly grind and level the terrace; the terrace is subjected to post precise polishing by a resin bonder diamond tool; meanwhile, in the technical process, according to needs, the terrace is treated by using an infiltration hardener and a sealing agent. The technical method provided by the invention has the advantages of convenience in construction, operation time saving property, low cost, energy conservation, environment friendliness and the like, the terrace treated by the method is high in hardness, very long in service life, high in degree of finish and good in flatness, and the decorating effect is greatly improved.
Description
Technical field
The present invention relates to concrete floor processing technology, particularly a kind of concrete floor abrasive polishing process method.
Background technology
Concrete floor has compared with ceramic tile terrace, stone material terrace that flexibility of constructing is large, low cost and other advantages.But the planeness of concrete floor terrace when constructing is difficult to ensure, needs to carry out grinding and polishing to new concrete floor, improves its intensity, hardness, planeness and glossiness; Old concrete floor is due to the problem such as environmental factor of terrace paver quality or use procedure, and the phenomenon such as breakage, dusting may appear in terrace, need carry out repairing, renovating.Existing conventional abrasive polishing process is: corase grind, fine grinding, ground cleaning, wax, existing technique can play a role to ground, but intensity, hardness are poor, ground is shorter for application life, simultaneously, fineness effect is relative with planeness poor, thus makes it use class lower, and range of application is restricted.In prior art, also exist, adopt the mode of water mill, but water mill can produce a large amount of waste muds, cleaning is inconvenient, not energy-conserving and environment-protective.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide one can obtain good combination property and more high gloss, and concrete floor abrasive polishing process method that is convenient, that save activity duration and cost of constructing.
Object of the present invention is achieved through the following technical solutions: a kind of concrete floor abrasive polishing process method, comprises following steps successively:
(1) use terrace polishing machine to carry out grinding leveling to concrete surface, select granularity be 20 metal-bonded diamond milling tool, tool shelf rotating speed is 600 ~ 800rpm;
(2) use terrace polishing machine join granularity be 60 metal-bonded diamond milling tool the concrete surface after step (1) process is further ground, tool shelf rotating speed is 600 ~ 800rpm;
(3) industrial dust collector cleaning floor is used; Cleaning is carried out to the concrete surface after step (2) process, use industrial dust collector, know powder, the particle left over after falling step (1) and step (2) leveling, for the enforcement of step (3) provides better execution conditions, powder when ensureing step (3) filling eye and gap is fine powder;
(4) evenly spray gap filler on ground, use terrace polishing machine to join the metal-bonded diamond milling tool that granularity is 120, tool shelf rotating speed is 600 ~ 800rpm simultaneously;
(5) after step (4) is air-dry, use watering can be sprayed on by compact agent on the concrete floor that process through step (3), compact agent consumption is about 0.25 liter of every square meter, carries out placement 6 ~ 12 hours after densified, natural air drying solidification;
(6) resin bonding agent diamond instrument is used to carry out grinding and polishing to concrete surface, carry out 5 ~ 7 grinding and polishings, metal-bonded diamond milling tool fine size selected by the front grinding and polishing of metal-bonded diamond milling tool fineness ratio selected by a rear grinding and polishing, metal-bonded diamond milling tool granularity is: 50 ~ 60,80 ~ 100,170 ~ 200,325 ~ 400, W20, W10, W5, the rotating speed of instrument rotating disk is 800-1000rpm; Wherein, the grinding and polishing number of times of this step is determined according to concrete surface state, general needs advanced person uses and carries out 2 ~ 3 fine lappings compared with the diamond disk of coarseness, selected diamond grit is 50 ~ 60 or 80 ~ 100 or 170 ~ 200, then use the diamond disk of fine particle size to carry out the polishing of 3 ~ 5 times, selected diamond grit be 325 ~ 400, W20, W10, W5.
(7) evenly spray one deck protective agent on ground, natural air drying is after about 2 hours, and use the terrace polishing machine being provided with polishing pad to carry out polishing encapsulation process to concrete surface, instrument rotary speed is 800-1000rpm.
Further, the Concrete Filled agent consumption that step (4) is added is about 0.25 liter every square metre, step (4) in sprinkling or smear Concrete Filled agent, with this simultaneously, carry out grinding and be evenly coated with sweep grinding the powder produced, joint filling filling-up hole, take full advantage of the fine powder that grinding produces, with gap filler by powder consolidation, keep the material of joint filling filling-up hole and the maximum similarity of former concrete floor material, joint filling filling-up hole is effective, improves the intensity of concrete floor.
Further, to the concrete surface after step (4) process, after air-dry, watering can is used to be sprayed on by compact agent on the concrete floor that processed through step (4), compact agent consumption is about 0.25 liter of every square meter, reusing watering can after 15 ~ 20 minutes is sprayed on concrete floor by compact agent, compact agent consumption is about 0.1 ~ 0.25 liter of every square meter, then spontaneous curing is carried out after 6 ~ 12 hours, carry out step (6) again, wherein, smear the densified that compact agent carries out in this step and can carry out 1 ~ 3 time, basis for estimation is, smear compact agent, after natural air drying 15-20 minute, concrete floor has the even tiny globule of one deck, it is moist feeling that hand touches ground, show that densified effect puts in place, on the contrary, after natural air drying 15-20 minute, there is not this phenomenon, then need again to carry out densified, this process can obtain good fine and close effect, greatly improve intensity and the hardness of concrete floor.
The present invention has the following advantages: the present invention adopts metal-bonded diamond milling tool, and abrasive polishing process step is few, simple to operate, saves the activity duration, meanwhile, also greatly reduces cost; After twice corase grind, and then joint filling filling-up hole technique and compactness treatment process, achieves good joint filling filling-up hole effect and compactness effect, substantially increases intensity and the hardness of concrete floor; What adopt resin bonding agent diamond polishing tool and polishing pad carries out concrete fine lapping and glossing, can obtain the terrace surface that glossiness is high, gloss is evenly bright, good decorating effect.
