Background technology
Construction Party at some emphasis venues is more and more higher in the face of the requirement of exterior coating, and strict day by day to the requirement of building coating, especially aspect the anti-pickup of exterior wall, particularly anti-rainprint aspect especially comes into one's own.
Therefore, this area needs a kind of film experimental provision of anti-rainprint quality of coating of measuring.By assessment to the anti-rainprint quality of a coating products, can be evidence-based, more convenient and effective when new product development and product improvement.
But, lack unified approach and standard that rainprint is identified in the market.For this reason, this area presses for the apparatus that can quick and precisely judge the anti-rainprint that coating is filmed.
The utility model content
The purpose of this utility model is to provide a kind of film device of anti-rainprint of coating of measuring, and is beneficial to implement unified approach and the standard that rainprint is identified.
Measure the film device of anti-rainprint of coating, be characterized in, comprise pedestal, model fixed support and pollution source platform, pedestal has installed surface, the installed surface of pedestal has a setting height(from bottom) with respect to base bottom, the pollution source platform flatly is provided with and above the installed surface of pedestal, be formed with many parallel grooves on the pollution source platform, both sides along the pollution source platform of the bearing of trend of groove respectively are connected with described model fixed support, the relative horizontal direction of this model fixed support has the angle of inclination, and the fixed support upper end connects the pollution source platform, and the lower end connects the installed surface of pedestal.
The film device of anti-rainprint of described mensuration coating, its further characteristics are that described angle of inclination is 15 degree.
The film device of anti-rainprint of described mensuration coating, its further characteristics are that described pollution source platform is a corrosion resistant plate.
The film device of anti-rainprint of described mensuration coating, its further characteristics be, the position that described model fixed support is used to contact model is antirust position.
The film device of anti-rainprint of described mensuration coating, its further characteristics are that described pedestal is the stainless steel pedestal.
The passive platform level prevents, go up fluted, dust stratification easily, easily produces current like this, arranged the model fixed support respectively in platform groove bearing of trend both sides, the current that the produce model on the model fixed support of flowing through, the tracking of the open air by a period of time so just can be used to judge the anti-rainprint of coating products, thereby can effectively guarantee the anti-rainprint of product so that evidence-based when the improvement of new product development and product.
