Ukuleles are the smallest guitars, and Ukulele has three size, soprano, concert, and tenor.
Soprano is for children, concert and tenor are for teenagers and adults.
Ukuleles have different quality.
The color ukuleles are for children, can be offered as gift.
Mahogany and spruce ukuleles are more professional, and the sound is better than color ukuleles.

Exterior wall paints are rich in color, flexible and diverse in decoration, capable of expressing rich and colorful architectural styles, simple in construction, light in weight, safe and reliable, especially with the promotion of building energy-saving and exterior wall thermal insulation technology, exterior wall coatings have become China's The main product of exterior wall decoration.
The lack of stain-resistance ability of the coating is a common problem common to external wall coatings, and it is also a prominent technical problem that restricts the popularization and application of external wall coatings in China. With the acceleration of industrialization, air pollution in cities and towns has become increasingly serious. The disadvantages of poor anti-fouling performance of products such as elastic paints, real stone paints, and embossed hairs are particularly prominent. At present, the production company mainly adopts the principle of hydrophobicity to modify the coating and emulsion system (the so-called "Lotus effect"). However, the practice of the application proves that its effect is not ideal and does not fundamentally solve the problem. The main reason is that the hydrophobic product is generally lipophilic, and existing atmospheric dust contains quite a lot of N0x and S0x organic substances. It is easier to adhere to ash on summer and low elasticity coatings with low glass transition temperature, and it is difficult to remove. Second, use nanometers. The grades of additives that modify the micron-sized emulsions and coatings, but also to surface functional effects in the coating, difficult, high cost, from the perspective of product design is not entirely reasonable.
The main functions of Minggu external wall self-cleaning coating material are as follows:
In the laboratory, according to the national standard method, through the coating treatment on the surface of the coating, the stain resistance index of the elastic coating and the embossed elastic coating can be reduced from 25% to about 10%, and the improvement effect is more than 60%. The improvement effect of C, pure C, and real stone paint is also about 40%.
The comparative test of exposure in the natural environment (3 to 9 months) has proved that the actual improvement effect of superior grade silicone-acrylic coating with a stain resistance index of 9 is greater than 60%. The product also has ultraviolet absorption, color retention, antibacterial and anti-algae activity. , air purification and other functions, the coating is colorless, transparent, no film, can maintain the permeability of the material, does not change the structure and appearance of the coating. Neutral water base, non-toxic and harmless, safety and environmental protection, convenient and efficient construction, and reasonable price.
The project and its core technologies were investigated by statutory bodies as the first in the country. It was listed as the key project of the company's 2007 annual corporate technological innovation and innovation fund support project. Its products have been accepted by large-scale domestic paint companies and exterior wall coating companies. good.
This technology provides new ideas for coating product development and can be used as an accessory product for exterior wall coatings and exterior wall thermal insulation coating systems. It is also entirely possible to be the best way to solve the problem of coating stain resistance and self-cleaning and color retention. And methods, have a good market development prospects and promote the application of value.
The self-cleaning effect of light energy is the most attractive method for preparing self-cleaning coatings in the contemporary world. It absorbs the ultraviolet light in the sunlight to produce a decomposition and superhydrophilic effect on the surface oil, thereby producing a self-cleaning function. Such technologies and products have been successfully applied in the fields of automobiles, glass, ceramics, and lamps. Fuzhou Minggu Nanotechnology Co., Ltd., with the cooperation of the Chinese Academy of Sciences and other units, successfully applied it to the self-cleaning protection of exterior wall coatings, and established a relatively complete performance evaluation system, and has a set of construction application methods.
