Floor QiChang share floor lacquer surface bubbles causes and prevention measures

Floor QiChang family share the causes and the prophylactic measures of floor lacquer surface blister

because of the existence of moisture and volatile liquid coating or surface under high temperature and high humidity in drying process in many big disparity, irregular round vesicular muster the phenomenon, referred to as the blister. Blister mainly is caused by improper construction.

the causes and the prophylactic measures of floor lacquer surface blister

and floor lacquer coating surface bubbles very similar ills is coating & other; Prickly heat & throughout; Because & other; Prickly heat & throughout; Are similar in shape and sparkling, but generally smaller, cause have something similar.

the cause of the heat rash

A, paint on the substrate wetting ability is not enough, or substrate processing not net;

B, solvent volatilization too fast, using fast thinners or heat up too fast;

C, too thick or single layer construction each interval time is too short;

D, polyurethane paint containing water or dry in moist environment;

E, the lacquer that bake under 5 ℃ construction;

F, coating (not completely dry or exposure to moist environment Also may be completely dry) 。

the formation of prickly heat

the formation of prickly heat is more complex, the most likely cause is the solvent retention of prickly heat and moisture.

A, in the high temperature environment, severe solvent volatilization and strong solvent retention will cause the vapor were stranded in the film, to form A heat rash;

B, at a lower temperature, wet coating illiquid, especially the bottom surface due to solvent evaporation temperature, less liquidity, a more appropriate solvent steam stranded;

C, moisture also easy cause prickly heat, water and moisture in the environment construction in the paint miliaria evenly, and coating eroded by the moisture and heat rash often uneven, such as insect climbing generally have a certain pattern.

the sparkling preventive measures

A, improve the coating is dry, so as to improve the coating solvent release;

B, avoid dry bottom temperature under construction;

C, to reduce the solvent polarity, which reduces the coating's ability to retain the solvent;

D, use the correct surface additives, improve surface permeability;

E, use the right thinner and hardener.
