When the ink and fountain solution are mixed, the fountain solution is evenly dispersed in the ink with tiny particles to form an emulsion. When the water content in the ink reaches about 20%, a "stable" emulsified state suitable for printing will be formed. If the water content is too high or the pH value of the fountain solution is too low, it will cause problems such as reduced ink dispersion ability, reduced fluidity, unstable emulsification, and ink accumulation. Different types of inks will produce emulsification in different conditions. Compared with general inks, synthetic inks, metallic inks, and fluorescent inks are more sensitive to water content and pH. The emulsified ink will delay the drying time and increase the risk of back printing.
Solution:
• Correctly set the water-ink balance and continuously monitor it throughout the production process. • When the ink has been emulsified, clean the ink roller and re-ink the ink according to the correct water-ink ratio. 8dH ～ 120dH, pH value 4.8 ～ 5.5, temperature 10 ℃ ～ 150 ℃)
• If you use Heidelberg continuous alcohol system, you should use water and ink separation printing or use ink roller to blow off to eliminate excessive water. Excessive amount of water • Correctly adjust the ink roller • When printing small ink levels, adding extra ink bars to the layout will help the ink balance
The Polypropylene Joint for Plastic Infusion Container is made of the imported medicalâ€class polypropylene; where the material complies with FDA rule and passes the USP CLASS VI test. Beneath the joint, itis a shipâ€shape, which will form a plastic liquid infusion bag after welding with nonâ€PVC coâ€extruded film; the top opening is the inlet for loading liquid medicine. After filling the liquid medicine, the top opening will be melted to seal with the composite cap, and then form a complete softâ€bag liquid infusion product. The joint is produced in the clean plant, with the overall plant reaching to Class 10,000 and some for Class 1,000,000. The main working procedures, such as the injection molding, inspection, cleaning, inner packing and so on, are designed and processed as per the cleanliness requirements at the partial level of Class 100 , which passes the GMP onâ€site certification and complies with the cleanliness requirements of high capacity injection medicine.
The surface of production equipment is smooth, flat, and easy to clean and sterilize, with sound corrosionâ€resistant property, and inert to make chemical reaction with packing material. The precision and sensitivity of test and inspection instruments comply with the test and inspection requirements of products.
The polypropylene joint for plastic infusion container is mainly used for the pipe of nonâ€PVC softâ€bag.
