In the coating process of epoxy floor coating system, various coating film problems often occur shortly after coating or early in use, collectively referred to as early damage phenomenon, mainly means that foaming occurs within several months after the floor is put into use. Loss of light from the skin delamination phenomenon or some properties of the film can not achieve the goal. The following are some of the common construction processes and solutions.
Foaming problems with epoxy floor paint:
The blistering of epoxy floor paint is divided into two types: blistering on the surface of the coating and osmotic pressure blistering. The bubbling of the coating surface is mainly the presence of moisture and volatile liquids, the coating film is in the course of drying or at high temperature and high humidity. There are many uneven sizes on the lower surface. The phenomenon of blister-like irregularities in the shape of a circular bubble is mainly caused by water vapor in concrete. Small air bubbles produced when small bubbles escape during film cure. During the curing reaction, the fine pores of the pores do not close due to the increased viscosity of the coating and eventually remain in the dried paint film. To achieve the lacquer table, there is no residual air or, first, a good construction method is selected to reduce the air intake. However, in practice, the construction method has been determined by actual application conditions for most of the time. The method has a limited effect. The second is to reduce or eliminate microbubbles by adjusting the paint formulation. Specifically, the foam problem can be significantly reduced by selecting a low foaming raw material or adjusting the optimal viscosity, but this method is often limited by the predetermined performance specifications of the coating and the viscosity specifications during construction.
Epoxy paint bleed problem:
Bleeding refers to the phenomenon that when a paint of another color is coated on a paint film, the bottom portion penetrates into the paint film of the top layer and the paint film of the top layer changes color. The main causes of bleed are: 1 primer does not dry, 2 primer and topcoat color difference, 3 no primer or substrate contains color substances, 4 primer contains organic pigments.
Epoxy floor paint problem:
Hair flower is the uneven color of the coating film, and there are spots, stripes and hue. Generally, it is caused mainly by improper application of paint and deterioration of paint components.
Epoxy floor paint quit reason analysis:
There are roughly the following points:
1, Epoxy floor paint is not correct ratio, if the curing agent plus more and less there will be some problems, it is recommended that the ingredients must be used with electronic scales to match
2. Look at what you said. The surface is 24H or sticky. It looks like it will never dry. Tell you a way. Immediately use a solvent-free epoxy resin to scratch the surface. Wait until it is dry and then roll it. Layer paint.
Epoxy floor paint whitening problem:
Whitening is the phenomenon that the coating on the surface of the ground coating during construction or just after construction is milky white, and it turns white and loses light. The main causes are as follows: 1 The paint has a low boiling point and it volatilizes too quickly, which lowers the surface temperature of the coating and causes some of the water vapor to condense on the surface. 2 The air humidity is too high over 80. 3 A large amount of low-boiling quick-drying agent is used.
Epoxy floor paint wrinkle fisheye problem:
Wrinkle is a phenomenon in which the surface of the coating film shrinks and shrinks upwards due to the difference in the drying speed between the inner layer and the outer layer during the drying process of the coating, causing wrinkles or irregular lines on the surface of the coating film. Fisheye is a part of the coating after the coating is applied. Foreign matter that is present on or mixed in with the coating affects the uneven adhesion of the paint and causes shrinkage to expose the surface being coated. It is caused by the rapid volatilization of the solvent after the coating to make the paint less ready to replenish to form a large number of round beads or leather-like rings. The phenomenon of acicular holes like pores.
Epoxy floor paint bite orange peel bite bottom problem:
Pitches are localized shrinkages that appear on the surface of the coating after the coating is applied to form spots. Spots The surface of the coating produces a crater-like shape with a diameter of 0.5-3 mm. The surface of the uncoated surface is recessed: The orange peel is due to improper construction or high Volatile solvents evaporate violently, causing the surface of the coating film to show orange-striped phenomenon: discoloration is a phenomenon in which paint changes from one color to another in storage, construction, and use. : Bite at the end is the paint that softens and inflates the coating of the primer and bites and wrinkles and blisters.
Epoxy floor paint falls out of the bottom of the fullness problem:
The shedding is due to the fact that the floor cracking loses the original adhesion of the substrate. Under the action of the external force, the coating film is formed into a small part or the entire peeling skin is separated from the object surface. The phenomenon of insufficient exposure and fullness is the problem of raw materials and the cause of construction. In short, if you want to do epoxy floor paint, you must use good materials and use a professional construction team because professional is the guarantee of quality.
Epoxy floor paint loses light, sticky, rough, cracking problems:
Loss of light is just after the varnish or paint has been applied. The gloss of the paint film is full, but the gloss will gradually disappear after a long time. Stickiness means that after the paint is dry, it will stick or be sticky after some time. Sexual phenomena: Roughness is the phenomenon of irregularly protruding particles appearing on the surface or the entire surface of the coating after the coating is dried. It is generally caused by foreign matter in the coating and dust in the air: Cracking is commonly referred to as cracking. The floor is affected by various factors, resulting in hair-like cracks, fine cracks, coarse cracks, cracks and other phenomena.
