Two measures to prevent foaming on epoxy resin floor

人气: Article Source: Unknown Popularity: 发表时间:2019-01-04 -Published time: 2019-01-04
1: Do a good job in the storage of epoxy flooring materials, strictly control the moisture content of the pigments, fillers and solvents used; in the primer formula, try to prevent the use of soluble fillers; the use of solvents must coordinate its transpiration balance to prevent excessive solvents Residual; in high humidity environments, use low-permeability binders.
 
Two: Start from every link of the floor construction and pay close attention to details. During construction, it is necessary to prevent adverse weather conditions such as high temperature and humidity. The surface temperature of the construction should be maintained at a dew point of 3 ° C and the relative temperature should not be higher than 85%. If the coating is exposed to rain or condensation, frost, etc. before construction, it should be dull Before painting the next floor material; before construction, the floor material should be diluted and mixed and left to stand for a period of time before painting, especially the two-component floor material should have a certain maturation period, and then prevent mixing Evenness and reaction to the onset of heat, causing bubbles.
 
Control the thickness of the coating to reduce its water permeability; control the degree of sample survey on the surface, the roughness is too easy to leak coating, cavitation, and bubbles; after the substrate is pretreated, the surface must be kept clean and no electrolytes or dust can be left Impurities such as oil and grease that affect the adhesion of flooring materials; When using and storing products, try to prevent high temperature and high humidity environments, and reduce the chance of direct contact with water; When painting porous substrates, first apply a good permeability Seal the primer to remove as much air, solvent and other residues as possible from the holes.
