PVC plastic floor it is necessary to detect the ground conditions before construction and project standard assessment, mainly to do the following several aspects: 1) The intensity of fine stone concrete leveling layer ( Or cement mortar) Strength grade is more than C20, hardness tester is used to inspect the result should be not less than 1 floor surface hardness. 2 million mpa. Fine stone concrete leveling layer, Or cement mortar) Must not be empty drum, crack, sand. 2) The ground roughness within the scope of 2 m height error within 3 mm ( 2 m long detection rule) 。 3) Dry degree before construction should make sure that the ground is dry, concrete or cement mortar screed-coat at least more than the final set maintenance period of 28 days, the CNN moisture content tester were used to detect the moisture content of grassroots should be less than 3%. 4) Waterproof bathroom, washing, boiling water may be the site of contact with water for a long time, such as wall ground should do the waterproof layer ( The wall on the waterproof layer height not less than 30 cm) 。 Toilet, washing, boiling water on the ground level should be lower than other parts of the ground level 3 - 5cm。 The bottom floor floor, civil parties ( Or decorate party) Should do moistureproof layer. 5) And other materials at the junction of the elevation difference of ground material junction (other Carpet, marble, wood floor, floor tile, etc. ) Elevation difference should be in negative Within 6 mm. Linseed oil ground material laying bottom of the door leaf to the ground before H seam is 10 mm or greater. 6) Cross the work material construction forbidding overlapping construction. All materials in the construction, should be arranged in the early stage of the process have been completed after or before the final coating. 7) Construction material construction time limit for a project, each working procedure has certain curing period, and later construction is fine. In order to guarantee the construction quality, must ensure that sufficient construction period.
