Materials and properties

 

General purpose plastic nozzles are made of glass fiber reinforced polypropylene (PP1), polyoxymethylene (POM), and polyvinylidene fluoride (PVDF). These three materials have excellent chemical resistance and their maximum operating temperatures are 92. °C, 90 ° C, 150 ° C. Glass fiber reinforced polypropylene (PP1) material is the first choice for common applications, the most cost-effective; polyoxymethylene (POM) material has a better wear life; polyvinylidene fluoride (PVDF) is a super tough fluoropolymer It has excellent chemical corrosion resistance, is resistant to various acid groups, bases, amine groups and various halides, and has excellent anti-aging properties, and is especially suitable for production processes requiring ultra-purity.

 

Available in 1/8", 1/4" and 3/8" inlet thread sizes, the universal plastic nozzles are suitable for most common pipes and are available in a variety of flow and spray angles to suit a variety of needs.

 

Universal plastic nozzles provide two different types of spray patterns, fan and solid cone

 

Application range:

 

1. Printed circuit board solder mask cleaning 2. Circuit board development and etching process 3. Nameplate etching process 4. Other low pressure chemical syrup distribution 5. Humidification 6. Chemical manufacturing 7. Dust control

 

Applicable industry:

 

Industrial production areas of electronics, chemical, environmental protection, steel, machinery, painting, electroplating, textile, automotive, paper, medicine, food, etc.

 

1. Design features of the nozzle:

 

Quick-release nozzles enable effortless separation of the nozzle body and nozzle without the need for any tools; this convenient and efficient design allows for quick nozzle change, thus significantly reducing maintenance downtime in production.

 

The quick-release nozzle has an automatic and accurate alignment function, and the nozzle is automatically locked in the correct position when it is installed in the nozzle body, completely avoiding free time.

 

2. Types of etching machine nozzles

 

a. Yellow fan nozzle: characterized by strong impact

 

b. Yellow cone nozzle: characterized by a wide diffusion area

 

c. White fan nozzle: characterized by strong impact force and large flow

 

d. White cone nozzle: characterized by wide diffusion area and large flow rate

 

3. Arrangement of the etching machine nozzle

 

The arrangement of the nozzles of the etching machine corresponds to the type of the nozzles. It can be seen from the following figure that the nozzles of the etching machine nozzles are fan-shaped regardless of the fan shape or the cone spray. The difference is the difference in flow rate and pressure. , then we should be combined with flow and pressure to distribute. We can arrange the dispersion point for large pressure and flow. We can arrange a small amount of pressure and flow. The pressure and flow rate are determined according to the type of product. For deeper products, we choose a custom way of high pressure and flow; for products with deeper fine lines and fine sanding, we choose the most suitable method for small flow and pressure.

 

4. Number of etching machine nozzles

 

When the etching machine manufacturer customizes the etching machine to reinforce the etching machine nozzle, the etching machine nozzle is fixed on the swinging nozzle of the etching machine, and the arrangement position of each etching machine nozzle is distributed on the whole nozzle, then the arrangement position is We have already explained in three points. According to the third point, the number of the nozzles of the etching machine can be determined by combining the size of our nozzles. For example: 800mm feed width corrosion machine single nozzle etching machine nozzle number is 60, 7*8 cross-arranged on 8 nozzles; 1300mm feed width corrosion machine single nozzle etching machine nozzle number is 135 The granules were arranged in a 13*14 crossover on 8 nozzles.
