Design Basis
(1) Cleanliness requirements
1. For places with high requirements for cleanliness, self-leveling floors should be used. The higher the cleanliness requirements, the thicker the self-flow plane layer design should be.
(2) Physical and mechanical performance requirements
1. What vehicles are used during the use of the floor, how much load it is subjected to, how much impact it will be subjected to, and how much wear is suffered.
(3) Chemical resistance requirements
1. The type, concentration and contact time of chemical media that will be contacted during use (short-time contact, long-term immersion, etc.).
(iv) Flatness and appearance requirements
1. The flatness depends on the condition of the substrate, the thickness of the floor coating and the construction process; 2. The thicker the design of the floor coating, the easier it is to obtain better flatness; 3. The self-leveling and topcoat are easier to use. Get excellent flatness.
(5) Color design
1. The choice of color should consider the functions of each area, such as green channel, red forbidden channel and sign, yellow mark line, etc.; 2. High-purity requirements can choose bright colors (such as green, blue, etc.) In order to find dust and clean in time; 3, please refer to the "paint film color standard sample card" for color determination.
(6) Surface gloss
1. Select highlight (≥80%), semi-light (30-60%) or matte (≤30%) according to your needs.
(7) Other special requirements
1, non-flammability requirements 2, anti-static implementation standards and resistivity requirements.
(viii) Financial budget
1. Choose the right variety according to the budget.
(IX) Safety requirements
1. In the wet and slippery places or slopes with oil and water, you can choose anti-slip floor.
(10) Construction conditions restrictions
1. If the solvent is not allowed to be volatilized in the construction site, the solvent-free or water-based coating system can be selected. 2. The completely closed and non-ventilated place, considering the safety of the construction personnel, it is advisable to choose a solvent-free or water-based coating system.
Precautions
a, at room temperature, dry, ventilated place to store; b, avoid direct contact with skin, eyes; c, flammable products, not near heat source, fire source.
