In the construction process of epoxy floor paint, it is a powerful weapon to create excellent floor paint projects with advanced base treatment equipment, painting construction tools and quality control instruments. Epoxy floor paint, common construction tools and equipment of epoxy floor paint, according to the introduction, mainly includes the following aspects:
1. prime processing
(1) based on cement powder or grindstone,
(2) The vegetable land should be kept in good health for more than 28 days, and the water content should be less than 8% before it can be removed if there is unevenness or empty drum in the construction of the vegetable land.
Third, use epoxy mortar to patch the ground.
4. The oil pollution of prime land must be cleaned thoroughly.
Before construction, it is necessary to keep the construction site dry and clean.
2. bottom coating
1. Keep clean before construction. If there is any debris adhesion, remove the main agent and hardening agent according to the correct proportion and mix them fully.
Second, it is necessary to adjust the proper viscosity and finish the material within 4 hours according to the ground conditions.
3. The curing time of the bottom coating is about 8 hours.
3. medium coating
(1) Before construction, it is necessary to keep clean. If debris adheres, it is necessary to remove and mix the main agent and hardening agent according to the correct proportion and mix them fully.
(2) adding proper amount of resin to the quartz sand.
3. Use the trowel to evenly coat the material.
(4) the mixture should be completed within 30 minutes.
(5) handle the handover at the construction junction.
The curing time of middle coating is about 8 hours.
4. batches of soil
1. Mix the main agent and hardener in proper proportion and stir well.
Second, use the batch knife to coat the material evenly.
(3) the mixture will be completed in 30 minutes.
(4) soil curing time is more than 8 hours.
(5) according to the actual needs, the construction requirements of the construction must be smooth and no holes, and no batch cutter and sand print shall prevail.
5. surface coating
1. Keep clean before construction;
The main agent should be mixed before use.
Third, mix the main agent and hardener in the right proportion and stir well.
(4) use the roller or trowel to evenly coat the material and complete the material in 30 minutes.
(5) the handover should be done well at the construction junction.
_After the completion of construction, people can enter the building 24 hours later, and heavy pressure can be applied 72 hours later (based on 250C, the opening time should be prolonged at low temperature). 环氧地坪漆，环氧地坪涂料常用施工工具与设备
Epoxy floor paint, commonly used construction tools and equipment for epoxy floor coatings
Epoxy floor paint is made of solventless high quality epoxy resin and curing agent. Smooth, beautiful, mirror effect, with strong acid, alkali, salt, oil medium corrosion resistance, strong alkali resistance, excellent wear resistance, pressure resistance, impact resistance, high cleanliness and so on. It is suitable for highly clean, beautiful, dust-free, sterile electronics and microelectronics industries, pharmaceuticals and blood products industries that implement GMP standards, as well as floors of schools, offices and families.
1. Base surface processing equipment
1. Grinding machine: assemble diamond grinding tool for grinding concrete, terrazzo, hardened wear-resistant ground, marble and other base materials.
2. Portable grinder: It is used for grinding small area of concrete, terrazzo, hardened wear-resistant ground, marble and other base material surfaces or corners. It can also be used to remove small areas of old paint and paint layer.
3, milling machine: for milling, remove old paint layer, oil pollution layer.
4. Shot blasting equipment: used for large area of concrete, terrazzo, hardened wear-resistant ground, marble and other base material surface shot blasting treatment.
5. Vacuum cleaner: remove dust from the ground.
Two. Coating construction tools
1. Sawtooth trowel, nail shoe, nail roller: Sawtooth trowel is used for trowelling self-leveling floor paint, and then the air inside the film is released by roller pressing with nail. For local coating defects, the nail shoe can be worn to repair before the film surface is dry.
2. Flat-bottomed scraper: It is used for scraping thick floor coatings such as primer, mortar, putty, etc. It is suitable for scraping close to the ground.
3. Rollers and brushes: Excellent quality, non-hair loss roller and brush can get a good appearance, usually short hair roller has better operability.
4. Air-free spraying machine: It is used for spraying floor topcoat, with high efficiency, easy to obtain good decorative effect and easy to control paint consumption; spraying pump and nozzle should be selected according to paint viscosity and service life in order to obtain suitable fluid pressure and flow rate. Usually high-pressure airless spraying machine driven by electric or internal combustion engine is widely used because of its good portability.
5. Air spraying equipment: including air compressor and air spraying gun, which can be used for spraying low-viscosity floor coatings.
6. Mortar mixer, paver and polisher: used for construction of thick layer (> 3mm) resin mortar. The evenly mixed resin mortar is spread on the floor with paver and polished with polisher.
7, defoaming drum brush: applicable to floor paint construction, can eliminate bubbles, roll leveling effect is good.
8. Floor paint flat mouth, round mouth trowel: Made of manganese steel, suitable for floor paint, epoxy floor paint construction.
Three. Medium grinding equipment
1, large grinding machine: efficient and fast medium coating grinding equipment.
2. Polishing machine and abrasive belt machine: with 80-120 mesh abrasive discs and belts, we can polish the mortar or putty layer before finishing paint to obtain a smooth and delicate surface; with coarse (20-40 mesh) abrasive discs and belts, we can also use them for simple polishing of the surface of concrete and other substrates.
Four. Testing and testing equipment
1. Substrate Surface Temperature and Ambient Temperature and Humidity Meter: Determine the ambient temperature and humidity of the coating and the surface temperature of the substrate to determine whether it meets the coating requirements.
2. Substrate moisture content tester: used to determine the moisture content of the substrate to determine whether it meets the coating requirements.
3, conductive electrostatic resistance tester: used to measure electrostatic conductivity of anti-static floor. 五、其它辅助工具
Five. Other auxiliary tools.
1. Sewing machine and glue gun: for the treatment of cracks, the cutting machine is used to cut and modify the cracks into V-shaped or trapezoidal (5-10mm wide) for easy filling and filling; and the glue gun is used for filling polyurethane elastomer.
2. Weighing and mixing tools: Higher precision weighing tools are conducive to the accurate preparation of multi-component floor coatings in proportion, and the use of electric agitators to mix and mix sufficiently and quickly.
