In fine grained elastic layer when construction,, suggestion is adopted and is used the orthogonal direction construction, like this to improving smooth and compactness all is beneficial to.
7.5 scraping, drying takes time
The dry relative time of the curing of elastomeric material is longer, generally needs at least 16 hours ability to solidify, the weather of low temperature and high relative humidity, and hardening time can be longer.Before uncured, please don't enter into.
7.6 points for attention
The fine grained elastic material is the water-based material, and it solidifies drying is exactly the volatilization of moisture.It is pointed out that must not be for working to tight deadlines, with two-layer elastic material one-off construction.It is as a result the time, and elastic layer is too thick to cause forming behind the surface cure film of one deck densification, and the inside then exists a large amount of moisture to volatilize, never can be dry, and final whole elastic layer is not do in the surface drying forever, has only whole shovels to fall at last.
8.0 elastic material sealant
8.1 the effect of elastic material sealant
The construction of acrylic acid elastic layer, though thickness collocation construction smoothly from level to level comes up, even if after two-layer fine grained elastic layer is finished, its surface is still coarse relatively.The effect of elastic material sealant is the matsurface of thorough smooth elastic layer on the one hand, 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 characteristics of " band is hard in soft; have gentle just " that it has, it is played forms a connecting link, the effect of buffering transition, can effectively absorb the impact from the upper strata coating, avoid the excessive VERTICAL DEFORMATION of upper strata coating and produce a large amount of random segmentation cracks.Say that in essence sealant also can be considered a kind of texture layer, it also has raising 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 the sealant material is made up of acrylic acid elastomeric sealant, refining quartz sand 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.
Because the void condition difference of the final basal plane that forms of elastic layer, the quartz sand of selecting for use is also corresponding different.Cross to adopt when thick and use low mesh number quartz sand, otherwise, use high order to count quartz sand.General construction gets final product for 1 layer.The construction number of plies is too much, will offset the elasticity of elastic layer.
For improving flowability and the color representation power of material, also can suitably add some prestige acrylic acid and concentrate fabric.Like this, sealant then no longer is linen after solidifying, but the acrylic acid that adds 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 formation and is uniformly dispersed, and compound good leveling property, that be easy to construct can be added some clear water during hot weather in right amount.
8.4 construction
With the sealant mixed material linear windrow of growing up along the place, take off with glue and to 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 form " sand drift line ".The most crucial effect of sealant just is the matsurface of smooth elastic layer, makes it more closely knit and smooth, the basal plane that provides for the construction of acrylic acid texture layer.After sealant solidifies, whole audience inspection that micelle probe phenomenon in the nonelastic layer is arranged, namely indivedual micelles penetrate sealant, if having, then with grinding machine its polishing back are removed totally.The chip that polishing produces don't fail to be removed totally, otherwise residual chip can cause the acrylic acid coatings of follow-up construction the phenomenon of " shrinkage cavity " to occur, influences attractive in appearance.
Simultaneously, notice that setting up period has no-sundries to drop into the place, have, after the curing, must remove.
8.5 solidify drying time
The sealing material is at least 4 hours ability dryings generally, and thickness is more thick, and hardening time is more long, the weather of low temperature and high relative humidity, and drying time can be longer.
8.6 note explanation
Sealant is be laid on elastic layer lip-deep, so its material unit's amount ratio is bigger.The elastic layer finished surface is more coarse, and sealing material consumption is more big, and the quartz sand that contains is just more many, and rigidity is more strong, to the elastic reaction of elastic layer offset more many.Therefore, the construction quality of elastic layer (as surface roughness) must be controlled well.
9.0 acrylic acid texture layer construction
9.1 the effect of acrylic acid texture layer
The acrylic acid texture layer is the coloured coating that contains sand; it is the protective mulch of sealant; be again wearing layer and the ball velocity modulation ganglionic layer of whole acrylic acid coatings, can satisfy the client to the thickness requirement of place finished surface and the requirement of ball speed speed to texture layer adjustment according to requirement of client.The acrylic acid texture layer is emphasis and the key of whole acrylic acid structure.
9.2 material mixture ratio
The used material of texture layer is by the colored fabric that concentrates of acrylic acid, the mixed thing that 60～80 order quartz sands and clear water are formed, and its material configuration is as follows:
The colored fabric that concentrates of acrylic acid: 60～80 order quartz sands: clear water=10 gallon: 50kg:10 gallon.
9.3 stir explanation
Texture layer concentrates the mixture that fabric, refining quartz sand and clear water are formed by colored acrylic acid, can use mechanical agitator to stir, could blade coating after each component fully is uniformly dispersed.During the blade coating, after compound leaves standstill a bit of time, also need stir to guarantee uniformity and the levelability of compound when going again to carry material, be convenient to construction.
9.4 construction
With the texture layer compound that mixes along place length or the width linear windrow of growing up, take off with glue and to strike off drawout, scrape to take off when walking about and walk in step with each other, avoiding speed differs, it is even to hold the dynamics of taking off, guarantee that coating thickness is even, simultaneously, try not to form the husky trace line (being slight " windrow ") that is piled by the grains of sand.
No admittance before the texture layer drying.Will check have the place of husky trace line to root out with perching knife after the drying, interior other foreign material such as leaf that descend slowly and lightly also will be removed in the lump comprehensively.
The two-layer good performance in place that just can show of the general construction of acrylic acid texture layer.The two-layer texture layer blade coating of can orthogonal direction constructing respectively.
9.5 solidify drying time
Texture layer construction back generally needs curing in 4 hours dry, and low temperature and high relative humidity weather is then longer.
9.6 points for attention
Meticulousr during the texture layer construction, husky trace line does not appear as far as possible, and reduce and root out this procedure, meet the construction of acrylic acid surface layer 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 etc., even if after the acrylic acid surface layer completed so, the effect that presents was also had a greatly reduced quality.
When temperature is high, can add some clear water in right amount.
10.0 acrylic acid surface construction
10.1 the effect of acrylic acid surface layer
The acrylic acid surface layer has decoration function to color and luster and the surface of acrylic acid texture layer, thereby makes the final finished surface color of acrylic acid more even, and thickness is more consistent.
10.2 material mixture ratio

Acrylic acid concentrates fabric: clear water=10 gallon: 7～10 gallons.
10.3 stir explanation
The acrylic acid surface layer is the mixture that is concentrated fabric and clear water by colored acrylic acid, uses mechanical agitator to stir, and fully is uniformly dispersed until acryhic material and clear water.During the blade coating, compound leaves standstill little reaching again after the meeting and also needs an amount of the stirring to guarantee the uniformity of compound when expecting, avoids the inhomogeneous surface material that causes of material aberration to occur, when temperature is high, can add some clear water in right amount.
10.4 construction
The surface material that mixes along place length or the width linear windrow of growing up, is scraped to take off it is taken off with glue and flatly taken off evenly, scrape to take off when walking about and walk in step with each other, avoid sometimes fast and sometimes slowly, hold the not too big variation of the dynamics of taking off and angle, guarantee 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 is finished, otherwise the uniformity consistency of place color and luster can be damaged.
One deck acrylic acid surface layer can present good effect.For guaranteeing surperficial friction and avoid the surface too smooth that the surface layer number of plies is too much unsuitable, two layers of maximum blade coatings.
10.5 solidify drying time
Needed solidify behind the surface construction in 4 hours.Under the low temperature and high relative humidity situation, hardening time the president a bit.Before the affirmation drying, definitely can not enter into.
10.6 points for attention
The acrylic acid surface layer is the face of whole acrylic acid coatings, guarantee bright in luster, solid colour.Be sure not construction when temperature is too high, the weather of blowing also please postpone constructing to prevent that foreign material borrow wind-force to scrape in the admission outside the venue, thereby the acrylic acid facing surface is damaged.
The construction 11.0 rule in vain in the court
According to actual conditions, chalk is generally brushed 1～2 layer just can produce splendid visual effect.
11.1 stir explanation
Acrylic acid white line lacquer generally need not to add water, only need slightly stir evenly to get final product.
11.2 burst at the seams in the court
International standard according to place graticule size marks out with the boundary line on the basal plane of the acryhic material that completes, and sections out with wood bucket line bullet.Afterwards, U.S. line paper is sticked along the snap the line that bullet sections out, U.S. line paper must be pasted closely with the acrylic acid face, and wrinkling or segregation phenomenon can not be arranged.
11.3 line
For avoiding white line burr to occur, the inboard brushing of U.S. line paper can be gone up homochromy acryhic material on one side, thereby the burr of avoiding white line oil infiltration to form, treat its drying after, draw an instrument with hairbrush or spray gun or other specialty spray white line covered with paint or varnish on the zone, boundary line that is coated with or is sprayed between the U.S. line paper.
White line oil generally needs 4 hours drying times, and under the low temperature and high relative humidity situation, drying time can corresponding prolongation.
11.4 points for attention
When mark is drawn the court white line, might because of carelessness red stain be dripped to green area, or green material splashes into red area, wipe away in case find wettable cloth, as can not thoroughly wiping away, available small brushes point dips in the acrylic acid that does not add water and concentrates fabric and brush one time gently and get final product.
12.0 remarks explanation
12.1 base description
The present invention is only applicable to bituminous concrete basis and coagulating cement earth foundation, does not then recommend to use for other basis.
12.2 the crack can't overcome
Laid that acryhic material provided by the invention can not guarantee fundamentally that crack problem does not occur or do not come up from the basic crack reflection.In fact, acryhic material itself can't split cruelly, its crack all by basic crack upwards in the reflection with the acrylate layer drawing crack.
12.3 batching adds the water explanation
1. the configuration of acryhic material all need add water, phenomenon such as in case add dilutional hyponatremia, material concentration is too rare just to occur that aberration, foam, bonding force weaken, dusting and abrasion resistance reduction.
2. as if acryhic material amount of water deficiency, the compound viscosity increases, and can reduce the flowability of compound, can produce " traction " during construction, causes compound " windrow " to occur, finally causes the became uneven of coating.
3. the clear water that adds must be drinkable water, does not use well water, river or seawater etc.
12.4 batching adds the sand explanation
1. acryhic material all need be dosed quartz sand at construction levelling blanket, sealant or texture layer, and adding the sand amount must be in strict accordance with requiring configuration.In case it is too much to add the sand amount, the ratio of acrylic based emulsion and quartz sand is too little, and the compound viscosity of generation increases, the mobile reduction, can produce " traction " during construction, cause compound " windrow " to occur, produce finally that bonding force weakens, phenomenons such as dusting and abrasion resistance reduction.Coarse and the scratch of coating surface also can appear simultaneously.
2. if acryhic material adds the sand quantity not sufficient, can cause coating layer thickness not enough, 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, store and transportation in must carry out antifreezing measures, continued to be exposed to for a long time under the freezing environment, can cause that material is freezing can't to be used.
12.6 the anti-explanation of being exposed to the sun
