Waterborne coatings have three major advantages.
First, it is safer, healthier, and more environmentally friendly. The waterborne wood lacquer is non-flammable, basically odorless, and has a low content of VOC units, which reduces the risk of fire and the incidence of skin diseases.
Second, the film performance is good. In addition to all the properties of the traditional paint film, the water-based paint is more resistant to ultraviolet radiation, the color change is less, and the furniture items have a longer life.
Third, the construction performance is good, both in terms of dry time, construction temperature, recoating time, and filling properties, while waterborne wood paints can have up to 50% nonvolatiles, and traditional nitrocellulose paints are only 20%. Therefore, waterborne coatings can effectively reduce the occupational disease incidence of construction workers.
Although the waterborne epoxy floor has many advantages that ordinary epoxy floor does not have, it has been developing very slowly and has been in a buffer period. What is hindering its development?
In terms of price: Waterborne epoxy flooring is relatively expensive compared to ordinary epoxy flooring, and many consumers prefer to use solvent-free flooring.
Technological innovation: Many small and medium-scale paint manufacturers still have some obstacles in the mastery and development of water-based technologies, but these conditions have gradually been improved, and more and more domestic companies have already been able to develop water-based paints and R&D capabilities. It has reached the same level as foreign companies.
Policies and regulations: The laws and policies of the paint industry reflect the concept of environmental protection is still relatively limited, and some regulations currently in force are far out of date.
Consumer acceptance of cognition: Due to the low proportion of water-based epoxy floor applications, many consumers have lower awareness of it.
Concave Convex Drainage Board
Concave convex Drainage Board has a good drainage system of the civil construction period and normal use of structure in playing an important role. Drain and porous tubes an effective drain drainage system, cylindrical long-short drainage plate and Geotextiles is composed of a drainage system, thus forming the function of water seepage, water storage and drainage system.
Introduction:
Dimple Drainage Board is using blow molding method to produce high density polyethylene (HDPE) Geomembrane, pressed on geomembrane pressure after the special craft the closed swelled the frustum of a cone shape, having a three-dimensional space and some support stiffness, liquid, gas can flow excreted within its plate. This dimples which in spatial structure with certain height can resist long-term high pressure without deformation.
Concave convex drainage board instead of pebbles water drainage has the advantage of time saving, energy saving and saving investment, also can reduce the load of the building.
Drainage board plays an important role in good drainage system, the civil construction period and normal use of structure. Drain board and also called basement drainage is an effective drain drainage system, cylindrical long-short drainage plate and geotextiles is composed of a drainage system, thus forming a which has the function of water seepage, water storage and drainage system.
Advantages:
low-cost, high efficiency; durable; chemical resistance, resistance to puncture of plant roots; diverse application; simple installation and quality guaranteed.
Application:
Greening project: the garage roof greening, roof garden, vertical greening, roof greening, football pitches, golf course, etc.
2. Municipal engineering: airport, road embankment, subway, tunnel, landfill, etc.
3. Construction: the upper or lower building foundation, inside and outside the basement wall, floor and roof, roof seepage control and heat insulation layer, etc.
4. Water conservancy project: the reservoir seepage water, reservoir, lake water seepage control, etc.
5. Traffic engineering: highway, railway basement, roadbed, dam and slope protection layer, etc.
