Plastic Sprayers Manufacturer -Plastic Spray Bottle Product Features, Nozzle Properties

Nowadays, plastic spray bottles are widely used in the plastic packaging industry. What are the characteristics of plastic spray bottles and spray heads? Here is the answer from the    Plastic Sprayers Manufacturer    :

1. Plastic spray bottle is beautiful and smooth inside and outside, seamless without welding, light weight, good strength, impact resistance, corrosion resistance, non-toxic and tasteless, and convenient transportation.

2. Long service life, under normal filling, transportation and loading and unloading conditions, the shelf life is 1.5 years.

3 The technical parameters of the product strictly follow the guo standard. The product design and product size can also be tailored according to needs.

4. Can be used for hot filling, the general temperature should not exceed 60 ℃. After hot filling, the lid should be closed and stacked after the contents have cooled down sufficiently to room temperature.

5. If it contains easily dispersible chemicals, it can be equipped with a cover with a vent function to avoid the danger of overpressure during transportation, and at the same time to ensure the sealing performance to liquids.

Spray bottle product features: storage and stacking, canning, the entire process greatly saves space and material. Light weight, low temperature resistance, corrosion resistance, reduced pollution, super clean, at the same time, it has acid resistance, alkali resistance, high temperature resistance, non-toxic, sterile, odorless, and has excellent resistance to stretching and impact in accordance with the requirements of medical testing .
  
 The spray head of the spray bottle is made of polyvinyl chloride, and its production type is mass production. The spray nozzle material of polyvinyl chloride is a thermoplastic.
   
From the perspective of performance, PVC materials have flame retardancy, self-extinguishing properties, and no dripping properties. In addition, they also have high strength, good weather resistance, and good geometric stability. From the perspective of dielectric properties, polyvinyl chloride has good electrical insulation and chemical stability. From the perspective of molding, polyvinyl chloride has good water absorption, poor melt flow, low shrinkage, and molding is not easy. . In addition, spray bottles are prone to defects such as insufficient pouring and shrinkage when molding. When the molding temperature is relatively high, it is easy to decompose hydrogen chloride, and the injection speed is too fast to cause shrinkage. Therefore, care should be taken to control the molding temperature and residence time during molding. The injection system should be thick and short, the cross section of the inlet should be larger, and the cooling time should not be too fast. A large-diameter nozzle should be selected.
