First, industrial floor standards and treatment methods
1. In order to achieve the perfect effect of painting, our company recommends: For the leveling ground, our company participates in the leveling treatment of the cement screed at the construction site. When the civil works are leveled, the ground surface of the company is ground with our company's professional ground machinery when the cement is first set. Based on this, the surface effect of the epoxy coating layer will be smoother and brighter, and the service life will also be improved.
2. After the cement layer is dry (approximately 28 days), use a grinding machine to grind the ground as a whole, so that the surface is flat and all the cement pores open.
3. For oily dirt (oil, engine oil) on the concrete floor, first wash the surface with a special lotion and scrub it repeatedly until no oil is left.
4. If the floor is too alkaline (PH>8), use a special material to neutralize it, then rinse with water;
5. For wet ground, absorb water. Dry, sun light, hot air blow drying, burning, drying it to meet the construction requirements.
6. For the ground with old paint (such as emery ground and old paint ground), first remove the old paint with a special machine, and then treat the bad cement and corundum ground and coat the ground. After such treatment on the ground, the unstable old cement and corundum surface is removed and a rough surface is formed, thereby improving the adhesion of the new coating and increasing the service life of the coating floor.
(1) First master the size and quantity of the workpiece to be coated.
(2) According to the workpiece surface rust, the degree of oil pollution, calculate the basic working hours required for each workpiece surface treatment.
(3) According to the coating quality level requirements, determine the total number of man-hours required for the number of workpieces to be puttyed, the number of grindings, and the number of spray-painted layers.
(4) Determine the dryness of the putty, primer, and topcoat, and whether the “wet-on-wet†process is used (not recommended, and natural drying is preferred). Calculate the number of hours required for drying time.
(5) According to the size and quantity of the workpiece, determine the single operation or collective operation, grasp the single and a small number of workpieces, and the man-hours required for different conditions of single operation and collective operation. Generally large batches of workpieces can be properly reduced by 2% to 5% of the man-hours.
(6) For the fixed-type batch production with pipeline operation, the man-hours can be estimated according to the degree of division. According to the degree of complication of each process, working hours are estimated. Finally, a special temporary consumption of 5% to 8% of compensation time is added, which is the total amount of work required for a batch of products.
Second, epoxy floor construction process
A. Preliminary work
a) The surface water content of the construction floor shall be less than %;
b) The air humidity in the construction environment shall be less than 75%;
c) measuring the construction environment temperature, should be greater than 00C;
d) measure the flatness of the construction floor;
e) Measure the actual construction area of ​​the construction floor.
B. Grassroots treatment
a) remove old paint and paint spots;
b) remove concrete spurs and other projections from the original floor;
c) Remove the original ground oil pollution;
d) remove the damp part of the original floor;
e) to fill empty shells from the original floor;
f) squabble processing;
