FAQ

Main construction method of EPDM rubber particle square

1, the bottom line of the test
Reasonable arrangements for paving work, must first on the basis of measured on a set of scheme delimit good line, the site will be divided into slices, then according to the block by block paving.
2, basic brush coating
After passing the acceptance of foundation, in order to strengthen the foundation and surface material layer of adhesive, first on the basis of scraping a layer of special glue and diluent according to a certain proportion of mixed solution, with the rolling brush dipped in glue evenly coated, to be dry after start paving bottom black particles. 3, the underlying spread
Black rubber particles and special glue according to 6.5:1 weight ratio, with stirring device in the stir zone stirring evenly, used to send the skip sent to pre mark the boundary and scraping feet paving, rolling roller compaction. To be the bottom of the ground after curing layer spread. After a two to three hour cure again with rolling roller compaction, uneven places with a trowel pat flat, such as trowel, rolling roller sticky granules, dip a little thinner to smooth.
4, face layer spread
EPDM granule and special glue 4:1 ratio of weight, with stirring device in the stir zone stirring evenly, used to send the skip sent to pre mark the boundary, scraping feet paving, rolling roller compaction, should pay attention to the compactness, smooth degree, thickness, repeated rolling. After a two to three hour cure again with rolling roller compaction, uneven places with a trowel pat flat, such as trowel, rolling roller sticky granules, dip a little thinner to smooth.
5, marking the line of the survey
Draw the pitch mark line as required. After the line must be reviewed by the sports technician. Steel tape with straight part of the identification of the review, confirm, be required to sign painting.
EPDM plastic runway construction process description
The main raw material for the gas permeable plastic runway is adhesive and rubber particles, EPDM or PU particles, the product characteristics, the basic bottom surface and the construction process is more stringent requirements. Use my company's products should pay attention to the following points:
First, the basis of the requirements of the bottom
1, can be used for asphalt concrete or cement concrete pavement, and the requirements of a certain strength and stability (cement concrete foundation need to cut and expansion joints, can not do waterproof layer).
2, is strictly prohibited cracks and due to uneven frost caused by freezing.
3, the foundation must have a good degree of flatness and the provisions of the slope.
4, the surface must be flat, to ensure drainage.
5, the basic surface should be kept clean and dry, after the completion of the foundation, strict requirements for more than 21 days of the maintenance period.
Two, construction technology requirements
1, construction and classification of two kinds of construction technology, mechanical paving and manual pavement.
2, the surface pre treatment in conforms to the request in the foundation, first with the clean surface of butyl cannot have any dirt, dust, water (including watermark) and grease. After cleaning in based on uniform smear base glue (the thinner: glue according to the 3 - a ratio of 4:1 Mix), enhanced with the bonding capacity of the ground, to avoid cause irreparable consequences.
Must pay attention to the following questions, 3 sample test before construction
A: the use of materials, such as material ratio, material curing time is normal.
After b:24 hours to observe whether there is no solid phenomenon, as well as adhesion, strength and other properties to meet the requirements.
4, the preparatory work before the (manual) materials, tools, equipment (finalized, rollers, soap water, car, harrow, mixer, etc.), accessories and catalyst preparation.
5, the construction personnel requirements (manual) standard field runway construction personnel at least no fewer than eight: preparation, transport material two, paving two, assisting a.
6, construction (manual): material proportionally mixing, into the venue paving, heating (heating blowtorch) or stained with soap and water after the clappers patted, pat flat seam to keep overall smooth.
7, the site thickness requirements are generally divided into two times the construction, in order to 13mm as an example: the general bottom 10mm rubber particles and surface layer spray 3mmEPDM or PU particles.
8, construction matters needing attention (manual)
1) the best construction temperature 1535 C, high or low temperature, influence of construction.
2) use of stalls shop tools (commonly known as rake) must adjust the accurate scale (actual Mm1.5-2mm) according to the requirements, should be uniform.
3) mixing must be fully uniform mixing.
4) each batch of material should be connected, otherwise the connection is not good will have a joint.
5) must be neatly trimmed.
6) must be strictly in accordance with the proportion of ingredients. Depending on the particle situation, good with less glue, poor use of glue more; large amount of less, a small amount of. Rubber particle at the bottom: glue = 6 - 8:1; surface layers of EPDM or PU particles + powder glue paste = 1 + 0.3:1: (0.05-0.08), catalyst in general do not need to increase, if the environment temperature is lower than 10 DEG C, can be appropriate to add 5-10 per thousand.
7) surface to be sprayed with special spraying equipment (general spray two times).
8) surface layer of glue is divided into two kinds: one is a rubber with EPDM or PU particles +: glue = 1 + 0.3:1 spraying; the second is with EPDM or PU particles: (3:1) paving materials = 1:1 spraying.
