Construction technology: anti-static pvc floor
1. Material composition:
The pvc resin, plasticizer, stabilizer, filler, conductive material and color mixing material are scientifically proportioned and polymerized and thermoplastically formed.
a, beautiful appearance, can provide a variety of colors for users to choose;
b. Elasticity and good foot feel;
c, wear-resistant, low dust generation, durable and flame retardant;
Requirements for the ground:
The ground should be flat and dry (the surface of the cement floor should be white), without obvious unevenness, and the surface unevenness should be less than 2/1000mm.
Construction materials and tools:
a. Construction materials;
b, the floor, the use of anti-static semi-rigid PVC block plastic floor,
c. Conductive adhesive, the resistance value should be less than 104Ω;
d, copper foil (or aluminum foil) thickness 0.01-0.05mm width 20-40mm;
e, alcohol, industrial grade;
f, electrode, diameter 2-5mm.
a, scraper, used for coating conductive adhesive;
b. The rubber throwing head is used to hammer the plastic floor to make it fully bond with the ground;
c. Megohmmeter, voltage 100 volts, used to measure electrical conductivity;
d. Blades for cutting plastic floors;
e, welding gun, used for welding the floor.
1. Clean the ground and find the center line:
First clean the ground slag, then use a tool to find the center of the room, draw the center cross line, and ask the cross line to be divided into vertical equal parts.
2. Lay copper foil (or aluminum foil) network:
a. Paste the copper foil strips on the ground according to the specified size to form a mesh. The intersections of the copper foils need to be bonded with conductive glue to ensure the conduction between the copper foils;
b. Use a megohmmeter to measure the resistance between adjacent copper foils, and the resistance value should be less than 105Ω. If there is a problem, find the reason and re-paste it to ensure continuity between the copper foils;
c. At least four points per 100 square meters in the pasted copper foil network are connected to the ground wire.
3. Laying the floor:
a. Use a scraper to apply conductive adhesive on part of the ground;
b. Start laying the floor when the conductive adhesive feels sticky and non-sticky. When laying, it starts from the center position and spreads out to the surrounding area one by one, and taps it with a rubber hammer. Keep a distance of 1.5-2.0mm between the floor and the floor;
c. Continue to apply conductive adhesive with the trowel and cover the floor until the entire floor to be constructed is covered.
d. In the process of laying the floor, it must be ensured that the copper foil passes under the floor
e. Use the welding torch to soften the electrode at high temperature and fill the gap between the floor and the floor.
f. Cut the protruding part of the electrode with an art knife to complete the entire ground construction
g. During the construction process, a megohmmeter is often used to test whether there is continuity between the floor surface and the copper foil. If there is no connection, it is necessary to find out the reason and re-paste it to ensure that the ground resistance of each floor is between 105-108Ω.
h. After the floor is laid, the surface must be cleaned.
Construction quality requirements:
A. The ground resistance of the floor surface should be 105-108Ω.
B. There is no bubble on the surface and no shelling phenomenon.
C. After the construction is completed, weld the gap and clean it.
A. When placing items on the floor, avoid dragging heavy objects on the floor, and the contact surface should not be too small. If necessary, use a wooden block liner.
B. When walking on the floor, do not wear shoes with metal nails, let alone scratch and knock on the floor surface with sharp or hard objects.
C. Often use a squeezed wet mop to mop the floor, and the dirty places can be cleaned with solvents such as alcohol.
