1.0 fundamental importance

1.1 coagulating cement earth foundations, label is not less than C25, and thickness is not less than 150mm, advises lay damp-proof course in concrete foundation structure, and surrounding must have escape canal, and concrete surface can not iron trowel troweling, and the common texture face that wooden trowel closes up is ideal.The actual conditions casting plain concrete built according to place or steel concrete, and should at cutting shrinkage joint, appropriate position.

1.2 as not having damp-proof course in concrete pedestal structure, and confirm that basis does not exist phenomenon of turning one's coat, and constructs after suitably can processing to basis.

1.3 extremely frigid zones then should be considered in infrastructure layer, to add warming layer to resist sternly freezing of winter.

1.4 basic technologies require:

1. planeness: four meters of ruler discrepancy in elevation are no more than four millimeters.

2. the gradient: control between 5 ‰ to 8 ‰, wherein tennis court can only adopt use one-way slope.

3. cement concrete mark is not less than C25.

4. maintenance 28 days ability must construct in principle after cement concrete completion, but just can construct about general maintenance fortnight.

Based process before 1.5 constructions

1.5.1 comprehensive inspection of mass of foundation:

, can not there be greasy dirt on basis before construction, can not have loosening, the position of ghost, and grass roots or other foreign matter that may affect bonding force can not be had to exist.Exist once find that there is above-mentioned phenomenon, must be processed.Cleaning greasy dirt, destroys the weeds and digs up the roots, and loosens and will cut with the position of ghost, until whole place presents closely knit, smooth and hard surface.Cement concrete must be polished and pickling, after using industrial phosphoric acid or hydrochloric acid to be diluted with water, waters on concrete surface and soaks after 15 minutes, rinse well with giant.

1.5.2 the polishing of concrete pedestal:

Concrete foundation always has laitance on the surface, dust or earth, even leaf birds droppings, the pore in these foreign matters from being blockeds concrete, as removed obstruction acryhic material penetrated in concrete pore and go, this reason place that will be acrylic acid coatings peeling, delamination in the future.Therefore any foreign matter likely affecting acrylic acid and base bond power on concrete pedestal must be cleared up.The method of thorough removing uses levigator to polish exactly, not only will polish and remove foreign matter, also eminence lofty in place will be polished flat simultaneously.

1.5.3 the pickling of concrete pedestal:

After having polished, pickling must be carried out to concrete.The object of pickling is the concrete alkalescence of neutralization on the one hand, is the surface of further hacking and purification concrete pedestal on the other hand.The industrial phosphoric acid of 85% or the hydrochloric acid of 37% can be used, water after it and clear water are diluted and be sprinkled upon on cement surface, allow it fully corrode cement surface, after 15 minutes, with giant, whole place is cleaned up.Pickling adds high pressure the flushing of hydraulic giant, and make concrete pedestal by acid corrosion hacking, the foreign material simultaneously in pore are also cleaned as much as possible, make concrete pedestal basal plane not only clean, coarse, and no-sundries blocking in pore.

As what foreign matter concrete pedestal surface does not have really, after construction master worker accreditation, also can polish, but the consumption of the acid of pickling to suitably increase.But in any case, still advise polishing to concrete pedestal.

Must note: place must thoroughly clean up, definitely can not a little acid residual, otherwise, there will be the serious quality problems of acrylic acid coatings and concrete pedestal layering in the future.Acrylic acid, though acid by name, what in fact it presented on Acidity of Aikalinity is weak alkalescence.Basal plane has acidic residual, and run into the acrylic acid of alkalescence, consequently coating is peeled off from basis.

During the construction of fine grained elastic layer, suggestion adopts and uses orthogonal direction construction, like this to raising is smooth and compactness is all beneficial.

7.5 dryings are scraped and are taken time

The dry relative time of solidification of elastomeric material is longer, and generally need ability solidification at least 16 hours, the weather of low temperature and high relative humidity, hardening time can be longer.Before uncured, please don't enter into.

7.6 points for attention

Fine grained elastic material is water-based material, and its solidification drying is exactly the volatilization of moisture.It is pointed out that must not for working to tight deadlines, by two-layer elastic material one-off construction.During its result, elastic layer is too thick causes the rear film forming one deck densification of surface solidification, and the inside then exists a large amount of moisture and cannot volatilize, never can be dry, and final whole elastic layer is do not do in surface drying forever, finally only has all shovels to fall.

8.0 elastic material sealants

The effect of 8.1 elastic material sealants

The construction of acrylic acid elastic layer, although thickness collocation construction, smoothly from level to level to come up, even if after two-layer fine grained elastic layer completes, and its surface or relative coarseness.The matsurface of the thorough smooth elastic layer of effect one side of elastic material sealant, forms the topping of elastic layer on the one hand.Elastic sealing layer is another technological core place of whole elastomeric propylene acid structure, the feature of " soft middle band is hard; have soft just " that it has, make it play to form a connecting link, the effect of buffering transition, effectively can absorb the impact from upper strata coating, avoid the excessive VERTICAL DEFORMATION of upper strata coating and produce a large amount of random segmentation crack.Essentially, sealant also can be considered a kind of texture layer, and it is also improved thickness, regulates the effect of ball speed and surface roughness.

General two-layer elastic sealing layer just can produce splendid effect.

8.2 material mixture ratio

The mixture that sealant material is made up of acrylic acid elastomeric sealant, purity quartzite and clear water, material mixture ratio is as follows:

Acrylic acid elastomeric sealant: 40 ~ 70 order quartz sands: clear water=10 gallon: 50kg:10 gallon.

Due to the void condition difference of the basal plane that elastic layer is finally formed, the quartz sand selected is also corresponding different.Adopt when crossing thick and use low mesh number quartz sand, otherwise, use high order number quartz sand.General construction 1 layer.The construction number of plies is too much, will offset the elasticity of elastic layer.

For improving mobility and the color representation power of material, also suitably can add some prestige acrylic acid and concentrating fabric.Like this, be no longer then linen after sealant solidification, but the acrylic acid added concentrates the color of fabric, but color and luster is more shallow.

8.3 stir explanation

The abundant stirring of compound is absolutely necessary, and uses machine mixer fully to stir until is formed and be uniformly dispersed, good leveling property, the compound that is easy to construction, some clear water can be added in right amount during hot weather.

8.4 construction

Sealant mixed material is changed into long linear windrow along place, take off with glue and strike off evenly, scrape that taking off walks about wants paces even, avoid and neglect fast neglecting slowly, make sure to keep in mind not formed " sand drift line ".The most crucial effect of sealant is just the matsurface of smooth elastic layer, makes it more closely knit and smooth, the basal plane that the construction for acrylic acid texture layer provides.After sealant solidification, whole audience inspection to have micelle probe phenomenon in nonelastic layer, namely indivedual micelle penetrates sealant, if having, then after polish with grinding machine, removing totally.The chip that polishing produces don't fail to be removed totally, otherwise residual chip can cause the acrylic acid coatings of subsequent construction to occur the phenomenon of " shrinkage cavity ", affects attractive in appearance.

Meanwhile, notice that setting up period has no-sundries to drop into place, some words, after solidification, must remove.

8.5 solidify drying time

General at least 4 hours ability drying of sealing material, thickness is thicker, and hardening time is longer, the weather of low temperature and high relative humidity, and drying time can be longer.

8.6 note explanation

Sealant is laid on the surface of elastic layer, therefore its material unit amount ratio is larger.Elastic layer finished surface is more coarse, and sealing material consumption is larger, and the quartz sand contained is more, and rigidity is stronger, to the elastic reaction of elastic layer offset more.Therefore, the construction quality (as surface roughness) of elastic layer must be controlled well.

9.0 acrylic acid texture layer constructions

The effect of 9.1 acrylic acid texture layers

Acrylic acid texture layer is the coloured coating containing sand; it is the protective mulch of sealant; be again wearing layer and the ball velocity modulation ganglionic layer of whole acrylic acid coatings, client can be met according to the requirement of client to texture layer adjustment and the thickness of place finished surface be required and the requirement of ball speed speed.Acrylic acid texture layer is emphasis and the key of whole acrylic acid structure.

9.2 material mixture ratio

Texture layer material used is by the concentrated fabric of acrylic acid colour, the mixed thing of 60 ~ 80 order quartz sands and clear water composition, and its material configuration is as follows:

The concentrated fabric of acrylic acid colour: 60 ~ 80 order quartz sands: clear water=10 gallon: 50kg:10 gallon.

9.3 stir explanation

Texture layer concentrates by colored acrylic acid the mixture that fabric, purity quartzite and clear water form, and mechanical agitator can be used to stir, until each component could blade coating after being fully uniformly dispersed.During blade coating, after compound leaves standstill a bit of time, more also need when going to carry material to stir with the uniformity and the levelability that ensure compound, constructability.

9.4 construction

The texture layer compound mixed is changed into long linear windrow along place length or width, take off with glue and strike off drawout, scrape to take off when walking about and walk in step with each other, avoid speed to differ, hold the dynamics of taking off even, guarantee that coating thickness is even, meanwhile, try not to form the husky trace line (namely slight " windrow ") piled by the grains of sand.

Before texture layer drying, no admittance.Will check after drying, have the place perching knife of husky trace line to root out, other foreign material such as the leaf descended slowly and lightly in field also will be removed in the lump comprehensively.

Acrylic acid texture layer is generally constructed and two-layerly just can be shown the excellent performance in place.Two-layer texture layer can be constructed blade coating by orthogonal direction respectively.

9.5 solidify drying time

Generally need solidification in 4 hours dry after texture layer construction, low temperature and high relative humidity weather is then longer.

9.6 points for attention

Meticulousr during texture layer construction, there is not husky trace line as far as possible, reduce and root out this procedure, the construction of acrylic acid surface layer will be met with the basal plane of a complete smooth no color differnece.If the effect of texture layer is bad, as out-of-flatness, aberration is obvious, even if after so acrylic acid surface layer completes, the effect presented also is had a greatly reduced quality.

During temperature height, some clear water can be added in right amount.

10.0 acrylic acid surface construction

The effect of 10.1 acrylic acid surface layers

Acrylic acid surface layer has decoration function to the color and luster of acrylic acid texture layer and surface, thus make the final finished surface color of acrylic acid evenly, thickness is more consistent.

10.2 material mixture ratios

Acrylic acid surface layer material used concentrates by acrylic acid the mixture that fabric and clear water form, and its material configuration is as follows:

Acrylic acid concentrates fabric: clear water=10 gallon: 7 ~ 10 gallons.

10.3 stir explanation

Acrylic acid surface layer is the mixture being concentrated fabric and clear water by colored acrylic acid, uses mechanical agitator to stir, until acryhic material and clear water are fully uniformly dispersed.During blade coating, compound leaves standstill little going again after the meeting and also needs during feeding to stir with the uniformity ensureing compound in right amount, avoids the uneven surface material caused of material to occur aberration, during temperature height, can add some clear water in right amount.

10.4 constructions

The surface material mixed is changed into long linear windrow along place length or width, scrapes to take off it to take off with glue and flatly take off even, scrape to take off when walking about and walk in step with each other, avoid sometimes fast and sometimes slow, hold the dynamics of taking off and the not too big change of angle, ensure that thickness is even.

Make sure to keep in mind blade coating and must not form linear windrow trace.Can not root out again after surface layer completes, otherwise the uniformity consistency of place color and luster can be damaged.

One deck acrylic acid surface layer can present good effect.For ensureing the friction on surface and avoiding surface too smooth, the surface layer number of plies is too much unsuitable, maximum blade coating two layers.

10.5 solidify drying time

Need within 4 hours, solidify after surface construction.In low temperature and high relative humidity situation, hardening time president a bit.Definitely can not enter into before confirmation drying.

10.6 points for attention

Acrylic acid surface layer is the face of whole acrylic acid coatings, guarantees bright in luster, solid colour.Be sure not construction when temperature is too high, weather of blowing also please postpone construction and borrow wind-force to blow in admission to prevent foreign material outside the venue, thus damages acrylic acid facing surface.

Rule construction in vain in 11.0 courts

According to actual conditions, 1 ~ 2 layer, the general brush of chalk just can produce splendid visual effect.

11.1 stir explanation

Acrylic acid white line paint, generally without the need to adding water, only need slightly stir evenly.

11.2 burst at the seams in court

Boundary line marks out by the international standard according to place graticule size on the basal plane of the acryhic material that completes, and sections out with wood bucket line bullet.Afterwards, the snap the line that U.S. line paper sections out along bullet is sticked, U.S. line paper must be pasted closely with acrylic acid face, can not have wrinkles or separation.

11.3 line

Burr is there is for avoiding white line, can by inside U.S. line paper while brush upper homochromy acryhic material, thus avoid the burr that the infiltration of white line oil is formed, after its drying, white line covered with paint or varnish on the region, boundary line being coated with or being sprayed between U.S. line paper by hairbrush or spray gun or other professional spray planning tool.

White line oil generally needs 4 hours drying times, and in low temperature and high relative humidity situation, drying time can corresponding prolongation.

11.4 points for attention

When mark draws court white line, likely careless red stain is dripped to green area, or green material instillation red area, once find that wettable cloth is wiped away, as can not be thoroughly wiped away, available small brushes point dips in the acrylic acid do not added water and concentrates fabric and brush one times gently.

12.0 remarks explanation

12.1 base description

The present invention is only applicable to bituminous concrete basis and coagulating cement earth foundation, for other basis then not recommendation.

12.2 cracks cannot overcome

Lay acryhic material provided by the invention and fundamentally can not ensure that crack problem does not occur or do not come up from basic crack reflection.In fact, acryhic material itself can't split cruelly, and its crack is all upwards reflected acrylate layer drawing crack by basic crack.

12.3 batchings add water explanation

1. the configuration of acryhic material all needs to add water, once add dilutional hyponatremia, material concentration is too rare just occurs that aberration, foam, bonding force weaken, the phenomenon such as dusting and abrasion resistance reduction.

If 2. acryhic material amount of water deficiency, compound viscosity increases, and can reduce the mobility of compound, can produce " traction " during construction, causes compound to occur " windrow ", finally causes the became uneven of coating.

3. added clear water must be drinkable water, does not use well water, river or seawater etc.

12.4 batchings add sand explanation

1. acryhic material all needs to dose quartz sand at construction levelling blanket, sealant or texture layer, and adding sand amount must in strict accordance with requiring configuration.Once it is too much to add sand amount, the ratio of acrylic based emulsion and quartz sand is too little, and the compound viscosity of generation increases, mobility reduces, can produce " traction " during construction, cause compound to occur " windrow ", final produce that bonding force weakens, the phenomenon such as dusting and abrasion resistance reduction.Also there will be the coarse and scratch of coating surface simultaneously.

If 2. acryhic material adds sand quantity not sufficient, coating layer thickness can be caused inadequate, structural capacity and strength deficiency, abrasion resistance reduces, corresponding shortening in application life.

12.5 antifreeze explanation

Acryhic material is environment-friendly water-based material, must carry out antifreezing measures in storage and transportation, under continuing to be exposed to freezing environment for a long time, can cause that material is freezing cannot be used.

12.6 insolation proof explanation

Acryhic material, in storage or job site, should be avoided being exposed to the sun in the sun, should be placed on shady and cool place or cover overcover, avoiding direct sunlight.

The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
