What are the construction steps for polyurethane screens? Polyurethane screen has the characteristics of high wear resistance, strong flexing resistance, high screening accuracy and screening rate, low noise, light weight, simple installation and high comprehensive efficiency. There are universal applications in our production and life, detailed construction and usage methods are as follows:
The polyurethane screen can be constructed outside the site or inside the factory. It should be carried out in accordance with the principle of first outside and second. The correct method can make the construction completed first used in advance to ensure the timely need of the materials in the factory supply. The strict control of the construction process and the required materials can strengthen the quality of the entire project and reduce the construction period and construction costs.
Polyurethane screen construction requirements
1. It is required that the base surface is flat, clean, free of sand and loose.
2. During the construction, the base surface should be checked and accepted to ensure that it meets the requirements. First, apply a layer of primer, which must be even.
3. After the primer is cured, apply the second brush, and the brushing direction must be perpendicular to the previous one to prevent leakage, and apply three to five times in sequence.
4. After completion, before the waterproof layer is not cured, no one can get on the person, and the next procedure is not allowed, so as not to damage the waterproof layer.
1. Construction requirements:
① During the construction of polyurethane screen, the base surface should be flat, clean, free of sand and loose.
②The base surface should be checked during construction to ensure that it meets the requirements, and a layer of primer should be applied first. The primer needs to be even.
③ After the polyurethane screen primer is cured, apply the brush again. The direction of the brush needs to be perpendicular to the previous one to prevent leakage, and apply three to five times in sequence.
④ After the construction is completed, before the waterproof layer is not cured, no one is allowed to go on, and the next procedure is not allowed to avoid damage to the waterproof layer.
2. Construction sequence:
①Add the dry powder to the appropriate water and mix it to form a paste.
② The construction wall must be brushed first.
③ Use the pallet and trowel directly to the wall.
④ During construction, it is necessary to apply uniform pressure and compaction, and the surface flatness reaches the design standard.
⑤ After air-drying, other decoration processes can be carried out.
Under certain special conditions, the construction steps of polyurethane screens may change, but generally follow the above procedures. The previous construction link must create conditions for the latter link to be smoothly applied in various industries and strictly follow the method. To avoid errors.
