natural colored sand, lacquer colored sand, Hangzhou saling

  Lacquer has a decorative effect, exactly like marble, granite. It is mainly made by a variety color of natural colored sand power. Building which is decoratived by lacquer has a natural real natural color, give the elegant, harmonious, dignified of beauty,  suitable for all types of indoor and outdoor decoration of buildings.  Lacquer particularly use for the surface buildings decoration, can receive vivid and return to nature effect. Lacquer with fireproof, waterproof, bear acid and alkali, resistant to pollution. Non-toxic, tasteless, adhesive power, never fade and so on, can effectively prevent erosion of the external harsh environment to the building, so that extend the life of the building, the lacquer with good adhesion and resistance to freezing and thawing properties; therefore particularly suitable for In cold regions. Lacquer construction is simple, easy to do time-saving, and easy construction. Lacquer coating is very hard and con not be pulled by the nail, if the general good lacquer after three days can be pulled by the nail after three days in good weather conditions construction, we can think is that the coating is too soft,mainly because of  choosen emulsion is inappropriate.

  Them in the preparation of Real mineral varnish, adopt the emulsion which is the same as preparation paint, which led to that the content of emulsion is low in the formulation of Real mineral varnish, the coating is not tight enough due to the presence of a large number of gravel when filming. The study by  coatings researchers found: the preparation emulsion's bond strength use for Real mineral varnish should not be less than the  3MPa, the minimum film forming temperature should not lower than 15 ℃. Higher minimum film forming temperature may cause  not easily film's shortcomings in low temperatures, we can solve it through add appropriate film-forming agent.Film additives can completely volatile after the coating drying, generally does not affect the performance of the coating. Real mineral varnish chose emulsion, which has the higher bond strength and the higher minimum film forming temperature, which has fundamentally solved the problem that coating is too soft.
