2、 Performance

 

Fluorescent brightener 33 # is a kind of excellent whitening agent which is considered to be used in printing and dyeing and detergent. Many properties of morpholine gene were introduced into the whitening agent. For example, the acid resistance is increased, but the perborate performance is also very good, which is suitable for the whitening of cellulose fiber, polyamide fiber and fabric. The ionization of fluorescent brightener 33 # is anion, and the fluorescence color is blue light. The chlorine bleaching resistance of fluorescent brightener 33 #is better than VBL and 31 # the pH of the best dye bath is 7-10, and the fastness to the sun is 4. The main characteristics of the application in washing powder are: high coordination quantity, high accumulated whiteness, and can meet any requirement of detergent industry.

 

3、 Purpose

 

1. It is suitable for detergent, and is added into synthetic detergent and soap soap, which can make its appearance white and pleasing to the eyes, crystal clear and full.

 

2. It is used for whitening cotton fiber, nylon and other fabrics; It has excellent whitening effect on artificial fiber, polyamide and vinylon; It also has a good whitening effect on protein fiber and amino plastics.

 

4、 Usage:

 

The solubility of fluorescent brightener 33 # in water is lower than that of VBL and 31 μ g, and can be used by hot water to about 10% suspension. When preparing solution, it is advisable to use it with the solution. The solution should avoid direct sunlight. The amount of fluorescent whitening agent 33 # in washing powder is 0.1-0.5%; The consumption of printing and dyeing industry is 0.1-0.3%.

 

5、 Packaging and storage

 

Packed in plastic bags lined with iron or paper drums, with a net weight of 25kg or 50kg per barrel. It can also be packed according to the requirements of customers. Hard collision and sun exposure shall be avoided during transportation of the product. The product shall also be stored in a cool, dry and ventilated warehouse for a period of two years.
