Description

A kind of grinding renovation pad for stone material

Technical field

The utility model relates to stone material grinding tool, pad is renovated in especially a kind of grinding for stone material.

Background technique

The country has many buildings to mat formation using stone material, these stone materials in use by sole friction and moisture, All kinds of dirty erosions, can generate scratch, aging, loss of gloss, pollution phenomena such as, very influence stone material decorative effect, so stone Material in use, needs periodically to be maintained, and to maintain its beautiful aesthetic feeling, stone material nursing industry is started late in China, The stone material of most domestic at present is all maintenance to be carried out by cleaning infrastructure management company, but there are technology shortcomings, labour The incomplete problem of shortage, tool；Traditional stone material nursing care mode has the following problems:

1, complex process, effect are poor:

Stone material nursing process traditional at present is mainly divided to two links: physical grinding+chemical polishing.

1. grinding: using large-scale grinder, perhaps single-deck machine arranges in pairs or groups 3 cun or 4 cun of diameter of grinding come to stone material progress Milled processed, so that the aging part of stone surface and scratch pit-hole etc. be ground off.

There are following two points in these grindings:

Corase grinding is not durable: traditional hard grinding, abrasive material are all embedded in the resin of thermoset forming, these resin hardness intensity Not enough, stone material difference of height, clip are being destroyed, when grinding away stone material aging layer, resin mass stress is crushed powder and splits, and can make a large amount of Buddha's warrior attendants Stone mill material is consumed, and grinding is caused not to be durable；

Fine grinding goes out light hardly possible: because being hard grinding, the hardness of resin is considerably beyond the stone material polished in grinding Hardness can cause duplicate scuffing on stone material.

Instead because resin hardness height is not out of light when needing to polish, this is industry chief drawback.So tradition is hard Stone material substantially can only achieve the glossiness of twenty or thirty degree after matter grinding grinding.

Minimum requirements of the industry to stone material glossiness: granite: 80 degree or more；Marble: 75 degree or more；Microlite: 80 Degree or more；Artificial compound stone: 70 degree or more.

By above-mentioned standard it is found that simple be not able to satisfy existing market to stone decoration effect by grinding glossiness on the market Requirement, it is necessary to the stone material after grinding is processed by shot blasting.

2. polishing: mostly using the mode of crystallization to polish stone material on the market at present, principle is using acid knot The calcareous ingredient of brilliant material and stone material itself reacts, and generates micro- theomorphism, shape by the gravity and high-speed rotation of machine At one layer of bright caliche.

Want to reach good effect, the pass of grinding, which generally requires, to be reached 9 times, the pass of polishing 2 to 3 times, even more It is more.Installation grinding is repeatedly dismantled in process of lapping, every time the grinding quantity of disassembly installation for 6 multiple, when installation it is noted that Grinding is same number section, also to carry out cleaning classification after grinding disassembly, to apply at any time in polishing process and spill medicament.Entire engineering It all does, need to expend for a long time, working efficiency is very low.

2, technical difficulty is high:

Grinding and the two links of polishing, not only require height to pass, the requirement to technology is higher.

Such as: stone grinding, all necessary well word of each number section intersects, grinds multipass, to guarantee any region of stone surface All be ground to, slightly it is slack be easy for grinding stone material scratch throughout, it is rugged, uneven, generate wave sense etc..

During devitrification stone, there are problems that a critical point.Chemical agent is during rubbing down on stone face, stone Material is gradually to go out light, but this glossiness is not to throw more long brighter, and stone material is just after glossiness reaches a point The unexpected loss of gloss of meeting is commonly called as throwing stone material and cover, this loss of gloss point is known as loss of gloss critical point by industry.Since medicament rubbing down goes out light Process is very fast, the only short several seconds time, it is desirable to this loss of gloss critical point in hand, extremely difficult, technical operation difficulty Greatly.

Some another other emergency situations, such as grinding ablation stone material, acid medicine corrode stone material etc..These problems, just The master craftsman of working many years at last, cannot guarantee that can completely avoid.

3, poor universality:

Crystallization polishing medicament used, each is only applicable to a kind of or a few stone material, commonly a medicament, Effect is pretty good on a kind of stone material, and changing a kind of stone material may be just without effect.Some medicaments, it is also necessary to which two or more collocation make With could effectively go out light, it is connected to a newly built construction, encounters a kind of new stone material, needed to prepare a variety of crystalline materials and attempt repeatedly, Suitable material can be found.

4, to mechanical requirements height:

It either grinds, or polishing, all has higher requirements to the weight of machine, horsepower and revolving speed.Clean property industry Indispensable floor-cleaning machine can not carry out stone grinding and polishing since weight and revolving speed are all insufficient.

5, equipment handling of goods and materials is difficult, has security risk:

The machine material needed in stone material nursing mentioned above is very many and diverse and expensive.Moreover, stone material protects Machine material used in industry etc. is managed, purposes is also very single, is only suitable for stone material nursing, use is little in another aspect, even Substantially useless, but have to buy also, not buying cannot work.

Various grindings, pulvis slurry cream, machine material are a lot of, have used big money when buying, and must specially prepare an a room Between go to put them.Area is small not all right, because machine is mostly also big；It is stuffy not all right, because crystallization has centainly with chemical agent Volatility and corrosivity, influence environment；Light-exposed also not all right, because some medicaments and material are also easy to spontaneous combustion, there are safety Hidden danger；Must also inspect periodically, some medicaments, which are not sealed or have crossed the shelf-life, to fail, only this, machine material is deposited Storage just needs a large number of expense with management.6, the maintenance frequency is high:

The glossiness that crystalline material is worked it out is not wear-resisting.In use, it can be seen that just work it out it is very beautiful, step on couple of days effect Fruit is just decreased obviously, and once the loss of gloss that gets wet.It maintains repeatedly, it is with high costs.

It is to pass through machine because what crystalline material utilized is that acid ingredient reacts with the calcareous ingredient inside stone material Gravity and high-speed rotation generate micro- theomorphism and form one layer of bright caliche, to form light-out effect.It is calcareous at sub-prime Ground is inherently softer, and soluble easily in water.Once coming into operation, in the case where major pedestrian movement tramples or contacts water, being exactly can Rapid loss of gloss, therefore the glossiness crystallized is not wear-resisting.

7, side effect is big, waste of resource:

It is crystallized after grinding and maintains stone material by the way of polishing, it is found that it is unglazed that stone material the more maintains the more dim, just starts to protect Feeding glossiness is also very beautiful, and that does often just can not do light.This is because stone material, which does maintenance by the way of crystallization, to be had Following side effect:

1. fast stone material dusting:

This is because crystalline material be it is acid, in crystallization process, acidic materials be used for a long time, can corrode marmorean soft Matter part (calcium carbonate) and cement.Cement is in marble forming process, and under high temperature, condition of high voltage, formation is played The part of cementation.Long-term acid effect, so that marmorean binding material is exposed outside, equal to accelerating its dusting Process.

2. orange peel phenomenon:

The long-term corrosion function of crystalline material middle acid substance can be such that marmorean hole and crack increases, visual effect It is exactly that stone surface crackle is very deep, there is apparent small rut.It that is to say the orange peel phenomenon for the marble surface that we are commonly called as.

3. collapsing hole phenomenon:

The salts such as the oxalates generated in crystallization process remain in stone material hole, continuous moisture absorption water suction and dried Journey causes stone material and collapses hole phenomenon.

4. causing color difference:

The salt that crystallization process generates causes stone material to be difficult to expect color change, out with protective agent ingredient repeated action Existing color difference.There are many people to find the stone material of oneself, originally carefully, but while using, there have been indescribable color difference to show As reason is just this.

5. ablation plate:

Crystallization technique, it is also relatively high to the skill requirement of material and worker, if control is bad, it is existing to be easy to happen burning plate As.

Above-mentioned side effect is not only to have an impact to the dicoration and durability of stone material, and many places are asked in stone material When topic, solution, which is often pounded, changes new, the duplication of production of stone material, and serious mineral resources is caused to waste.

8, it pollutes:

1. polluting stone material:

It crystallizes in polishing process, needs largely to use steel wool.Steel wool is that mild steel is made to 0.125~0.189 milli The filament of rice and a kind of polishing material for forming, this filament are also much thinner than hairline, during the polishing process, produced with ground Raw friction, it is easily scaling-off.Steel wool disintegrating slag is difficult to clean up due to too tiny, since disintegrating slag main component is iron, and it is very tiny, It pierces in stone material pore, encounters aquatic rust and turn yellow, influence stone material beauty, it is particularly evident on white stone material.

2. polluting environment:

Steel wool pollution: the usable floor area of steel wool is smaller, and each steel wool can only throw 8 square meters or so, and cannot weigh It is multiple to use.One engineering is got off, and a lot of wastes are generated, and discarded steel wool, fiber is very tiny, so easily raw It becomes rusty, become a rust powder for sticking together yellow powder, be difficult to clean up.And steel wool belongs to combustibles, there are security risks.

Crystalline material pollution: crystalline material itself be it is acid, deal with improperly and also pollute the environment, and be harmful to the human body, Cannot odor road not directly or for a long time directly and skin contact be gone to nose.

Grinding pollution: grinding the 3 cun of 4 cun of grindings used in traditional stone material nursing care mode, will be through thermosetting in structure The molding abrasive material of method is fixed on sticky cloth with glue.What is played a role in process of lapping is abrasive material, and glue and sticky cloth only serve fixation The effect of abrasive material, when abrasive material is used to 2/3rds, grinding just cannot be used, and be constructed every time, have a large amount of grindings to be given up Abandon, be ground the sticky cloth and glue used, not can be recycled, also can not natural degradation, certain pollution is caused to environment.

9, the wasting of resources:

Mineral resources waste: traditional crystallization polishes mode, will cause stone material ablation, orange peel, collapse hole, color difference, dusting etc. Phenomena such as, shorten stone material service life, and mineral resources be it is non-renewable, the exploitation of rough stone block can cause very serious Environmental disruption.

Waste of material: traditional stone material nurses complex operation, and machine material used is very many and diverse, this intermediate presence Many wastes.Such as: the manufacture craft and action principle of conventional sheet cause a large amount of glue, resin, sticky cloth, diamond abrasive Waste, handling of goods and materials be not good at caused by go bad, volatilization, corrosion etc. waste；The idle waste etc. of machine.
