(1) Techniques and techniques for automatic mixing of printing and mixing The ratio of printing paste is also called printing and mixing. After using automatic matching technology, we also call automatic pulping. The automatic pulping system combines the printing and dyeing process, applies computer database technology and network technology to realize the management of the formula database for printing and dyeing, and then controls the pulping pump and valve through the industrial control computer to realize the process of automatic pulping. The whole system is to establish a database management system to use the computer to manage and control the system. The accuracy of the measurement is ensured by the 1g precision large scale electronic scale and the 0.1g precision sample electronic scale. The system is divided into a paste modulation system and a mother color modulation system.
(2) Basic principle and process flow of pre-treatment additive distribution system Using network technology, embedded system and automatic control technology, dyeing machine, desizing machine, scouring machine, bleaching machine (or de-cooking and bleaching machine), In the process of mercerizing machine, the temperature, steam pressure, vehicle speed, alkali concentration sensor, servo control, database and mathematical model are combined to effectively control the temperature, speed, solution concentration and reactor time of the whole production process. Get up, meet the requirements we need, ensure the stability of product quality, improve the efficiency of the machine and reduce production costs.
The change of the concentration of deoiled and bleached alkali and the concentration of hydrogen peroxide in the pretreatment line will affect the whiteness, colorability, hair effect, fabric finish and shrinkage of the grey fabric. Therefore, the quality of the bleached fabric is controlled by the process. keep it steady.
For the centralized distribution of lye, hydrogen peroxide and various other auxiliaries, the concentration of the mother liquor is first tested, and the distribution plan is based on the required concentration and the consumption forecast of the grey fabric.
During the operation, the distribution scheme is finely adjusted according to the concentration change measured by the actual dynamics, so that a certain concentration is maintained in the tank.
The same is true for other production lines, such as mercerizing production lines: it is required to maintain a constant concentration of strong alkali and control the alkali content of the fabric.
(3) Technology and process of dyeing scale material color matching system The dyeing scale material color matching system is basically the same as printing and mixing in machine realization. The main difference lies in the difference of formula library management and process flow. Recipe management is designed according to the needs of the process.
(4) Dyeing laboratory drips technology and process flow Before the dyeing order is made, the formula must be made first, and an order is often carried out for dozens or even dozens of experimental production analysis, and the drip system is to solve Designed and manufactured with thousands of experimental analyses. The system consists of a dye bottle (1000 ml), a stirring device, a dropping tube, an electronic scale, a control unit and a database computer.
Each dye bottle is filled with a different dye which is stirred by a stirrer to prevent precipitation. Each dye bottle is connected with a separate pipe. The pipe is equipped with a miniature solenoid valve. When a certain dye ingredient is selected, the corresponding solenoid valve is opened, and the dye is sent to the measuring cup of the electronic scale by the siphon principle. The entire system completes database optimization and batching control through the database management system.
3100 Reflective Film For Advertising
Reflective film, is a film has been made directly applicable retroreflective material. Made using glass bead technology, microprism technology, synthetic resin technology, thin film technology and coating technology and microreplication technology. Usually there are white, yellow, red, green, blue, brown, orange, black.
The Advertising reflective film belongs to economic grade reflective film, different from general engineering grade. It can replace multicolor lettering signs, and can silk-screen printing. It consists of catadioptric glass beads which are embedded in a transparent layer of plastic material. The smooth surface has a high scratch resistance and a good printability. Self-adhesive retroreflective films with an excellent adhesion on metallic surfaces as aluminum and zinc coated steel plate.
>waterproof,sun-resistant >less working procedure and low cost >excellent corrosion and solvent resistance >scratch resistance and a good printability
