The bristles are an important part of the paintbrush, which is directly related to the use, effect and service life of the paintbrush. When Pengyu Tool purchases this part of the raw materials, it strictly follows the demand standards, and does not make false or shoddy products. The bristles used for brush making by Pengyu Tool generally refer to the bristles that grow over 4 cm on the neck and back of the pig. They are rigid, flexible, not easily deformed, resistant to moisture, and not affected by heat and cold.
Boiling is an indispensable process for processing bristles. The purpose is to deodorize, degreasing and disinfection. Before boiling, there is also a process of loading the semi-finished bristles (which meet the standard requirements of semi-finished products) into aluminum cans. The reason for this is to pave the way for the next step of boiling. The pig bristles loaded into the aluminum cans should be flush and straight at both ends, without curved bristles, so as to ensure the straightness after being boiled and shaped.
Put the sieve that has been installed in the aluminum can into the water (wooden tank, preset tank, iron can), and then put clean water to submerge the bristles to a depth of 10cm, and put steam appropriately. After the water temperature reaches 100 degrees Celsius, keep the constant temperature not low. in 4 hours, then add ammonia water with a concentration of 24% to 25% to shape the bristles.
After completing the most important part of the bristle processing process - boiling, the next step is drying. The bristles put into drying should be arranged in batches and layers and neatly arranged in the drying room for drying, and the drying temperature and time should be flexibly controlled according to different colors and specifications. Under normal circumstances, the drying temperature should be 80 degrees Celsius to 90 degrees Celsius for 24 hours.
Spread the dried bristles on the chopping board, mix and blend one to three times to make the tips of the bristles even. After such a fine peak matching treatment, the bristles will achieve 100% Soft and Flexible. When you paint with Pengyu Bristle Paint Brush, the peaks of the hairs are neat, the peaks are closed, the thickness is uniform, and the bristles are not split or bristled.
