0010010 nbsp; 0010010 nbsp; 0010010 nbsp; the viscosity isAcrylic emulsionA very important performance indicator, do you know what factors affect the viscosity of the emulsion? Next, let's take a look!

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; When the solid content of acrylic emulsion is <35%, the="" viscosity="" of="" the="" emulsion="" does="" not="" change="" with="" the="" solid="" content,="" when="" the="" solid="" content=""> {{ 3}}%, the viscosity increases with the increase of solid content, when the solid content> 55%, the viscosity increases greatly with the increase of solid content.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; The viscosity decreases as the emulsion particle diameter increases, and when the particle size reaches a certain level, the emulsion viscosity will decrease.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; When the latex particles are oval, rod, strawberry, snowman and other irregular shapes, the viscosity is higher than the spherical .

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; When many latex particles are grouped together and dispersed in groups, the viscosity of the emulsion is relatively high.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; When using polyvinyl alcohol, sodium polyacrylate, hydroxypropyl cellulose, etc. as the protective colloid of acrylic emulsion, the viscosity and protection of the emulsion The type, function and molecular weight of the glue are related.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Pure Acrylic Emulsion: The trend of China ’s pure acrylic emulsion market is relatively stable in 2015 year, except for raw materials affected by Low prices and weak downstream demand have affected the price decline to a large extent, and maintained a relatively stable level throughout the year. Compared with 2015 annual price trends 2013 and 2014 annual price trends, overall The price is lower, and the price of pure acrylic emulsion is less affected by the raw materials. 0010010 nbsp;

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Styrene-acrylic emulsion: The overall average price of styrene-acrylic emulsion in China in the year 2015 is low, as can be seen from the figure on the left, { {3} Since the beginning of the year, the price curve has been at a relatively low level, mainly affected by low raw material prices and low downstream demand, and the market has been weak. 0010010 nbsp;

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; China ’s acrylic emulsion production capacity continues to grow

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 2015 China ’s acrylic emulsion production capacity is 295. {{5}} tons 2014 year-on-year increase of {{7}. 5%, but the operating rate has dropped significantly, and it is expected that the average operating rate for the whole year of 2011 5 will only remain {{10 Within}}, the estimated total output in 201 5 is around 200,000 7 tons.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; From the statistics of the production capacity, output and operating rate of acrylic emulsion in recent years, it can be seen that although the production capacity of acrylic emulsion continues to increase, the operating rate has been increasing year by year The decline indicates that the acrylic emulsion production capacity is facing surplus.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; However, some analysis predicts that there will still be room for growth in China ’s acrylic emulsion production capacity in 2016 years, and that in 2016 Will continue to grow to around 320 tons. 0010010 nbsp;
