1.
After pouring, the water conservation curing shall not be less than 7 days, and the overall curing curing curing period shall not be less than 28 days (ensure the cement curing time, so that the white powder produced by the cement during curing can completely precipitate out of the foundation surface).
The products meet the requirements of gb36246-2018 and local standards, It can provide partners with bidding assistance, technical guidance for site foundation construction, stadium runway materials, plastic surface construction and other services.
Features of breathable runway: the bottom layer is made of adhesive bonded waste rubber particles, and the surface layer is sprayed with several particles of polyurethane mixed with Wang glue..
(d) joint filling on the surface strength of the foundation: after the primer of the plastic runway is cured, dilute it with the joint sealant and add 10% – 20% diluent (xylene or ethyl acetate) and brush it on both sides of the temperature joint with a brush, Then, the caulking foam is folded in half and gently filled with the temperature seam (the caulking foam is stretchable and compressible, which effectively reduces the influence of the change of basic thermal expansion and cold contraction on the surface appearance).
“So can it be constructed? We should also consider several points: is there any limit on the construction temperature of plastic runway? 1.
After washing and drying, the base surface shall be of the original color of cement without white powder and loose matter.
Foundation requirements: solid and flat (flatness requirements: the error of 3M ruler shall not be greater than 5mm), with a certain drainage slope of 0.4%, and the strength shall meet the C25 strength of building concrete standard.

(the function of primer is to penetrate into the micro holes of the foundation, block underground water and gas and strengthen the foundation surface after curing; the formation of bright film is to ensure that the micro holes of the foundation are completely blocked), Construction in the hot sun or high foundation temperature (> 450C) shall be avoided to ensure the permeability of primer (morning or evening without fog and rain is more appropriate).
If the temperature joint must be cut between the plates poured by plates, the width of the cutting temperature joint shall be 6 ~ 8mm and the depth shall not be less than 30mm (ensure that the thermal expansion and cold contraction of the foundation can be concentrated in the temperature joint and will not lead to cracking in other parts of the foundation).
4.
In principle, it shall be cut with a block of no more than 6x10m.
As long as there is no ice and the temperature is above 0 °, according to the manufacturer, they can be constructed However, the temperature close to 0 ℃ will also bring trouble to the construction, greatly increase the construction period, and make the site quality after the runway construction relatively poor.
2.
These materials cannot be constructed when the temperature is too low.
2.
pickling: wet the foundation with clean water (prevent dilute hydrochloric acid from penetrating into the foundation), evenly sprinkle and wash the base surface with dilute hydrochloric acid with a concentration of about 8%, and then rinse it with clean water (generally twice).
Foundation treatment: (joint grinding – acid pickling – primer – joint filling – leveling and repair) A.
Proper elasticity: porous molding material with moderate elasticity and rebound to reduce sports injury.
Professional construction machinery is applied to shorten the construction time.
It can be used after rain to improve the utilization rate.
Remarks: site design, materials and construction integration service manager Wu 18971153177 plastic runway course material manufacturer specializes in the production of plastic runway, new national standard plastic runway, EPDM plastic surface, silicon Pu course, acrylic course, artificial turf and silicon Pu course materials.
5.
Fast construction: due to the use of special materials, the construction does not have high requirements for the weather.
After the new cement foundation is poured, the expansion joint with reasonable temperature must be cut.
joint grinding: grind the base surface on both sides of the temperature joint into a width of 40 ~ 50mm and a depth of 3mm, so that the surface of the temperature joint becomes a “V” shape, (the width of 40 ~ 50 is to improve the bonding area between the sealant and the base surface and increase its bonding force.
Under what circumstances can the plastic runway be constructed? We heard many school principals say: “the temperature in winter is too low to be constructed.
primer: after the foundation is dry enough, use special primer to roll on the foundation surface in multiple passes.
3.
For more information, please consult: 18971153177 plastic runway course material manufacturer Wu Xinlong (wechat same number) sports ground material manufacturer.
Is there any limit on the construction temperature of plastic runway? Youzheng sports 18971153177 plastic runway course material production and sales + supporting professional construction.
The exposed part of the caulking foam is ground flat with a portable grinder, and then the “V” groove is filled with caulking glue in more than two layers (the thickness of one filling is not more than 1.0mm, too thick will foam and affect the performance of caulking glue).
2.
B.
Strong weather resistance: the special rubber particle surface can resist the pollution of ultraviolet ozone, sulfite and gas and prolong the service life.
In principle, the foundation surface forms a bright film after brushing, and the deficiency must be repaired until it is enough.
The depth of 3mm is to ensure the thickness of the sealant without occupying the position of the elastic layer, and ensure good overall cushioning, so that the thermal expansion and cold contraction of the foundation will not affect the surface of silicon PU).
During pickling, the accumulated water level shall be circled and marked.
Some plastic runway materials are liquid, such as glue for construction and PU materials.
High cost performance: no particles on the surface, easy maintenance and saving management costs.
Therefore, Xiaobian recommends here that the construction of plastic runway should try to choose a period with mild climate.
