  Function of Pillow Hot Melt Glue Packaging Machine Automatically fill molten hot melt glue into packaging film (PE film/composite film) to form pillow-shaped packages. Replaces traditional cutting method to avoid adhesive block adhesion and contamination, beautiful packaging, easy storage and transportation. Maintains colloid activity and stable performance to prevent secondary contamination. Pillow Hot Melt Glue Packaging Machine Working Principle 1. Colloid melting & insulation From hot melt glue reactor or storage tank, the material is kept at 160-200℃. 2. Automatic bag making The roll film is folded by the former to form a pillow bag shape. 3. Quantitative filling The screw pump or gear pump measures and injects hot melt glue into the bag. 4. Heat sealing High temperature sealing to ensure that the seal is firm and leak-free. 5. Cooling and shaping The pillow-shaped hot melt glue block is formed through the cooling conveyor belt or water cooling tank. Technical Features o...

JCT provides hot melt glue production line turnkey project. Factors affecting the color of hot melt glue Raw material color: Some base resins (such as rosin modification, SBC, EVA) are slightly yellow or amber. Tackifying resin: Phenolic modified resin or rosin ester is darker in color, which will cause the finished product to be yellowish. Antioxidant: Added stabilizers such as BHT and IRGANOX are light yellow to brown at high temperatures. Fillers are additives: Some plasticizers, waxes, and ingorganic fillers may make the colloid milky or opaque. Whether it has been bleaches: Raw materials that have been bleaches or refined can improve transparency. Color Characteristics Common uses Transparent / white Beautiful appearance, high purity Electronic products, plastic packaging, fabric lamination, etc. Yellow / amber Strong viscosity, wide adaptability, relatively low cost Corrugated boxes, book binding, labels, ...

  What is dental resin vertical kneader? Dental resin  vertical kneader  is a high-precision, high-cleanliness, high-viscosity material mixing equipment, suitable for pre-mixing and degassing of composite resin, denture restoration resin, light-curing restoration resin, 3D printing dental resin, etc. in dental materials. Vertical Kneader Structure Vertical kneading cylinder: Jacket structure, supports electric heating or heat transfer oil circulation, temperature control within ±1℃. Z-shaped hollow blades: Kneading, stirring and mixing, suitable for medium and high viscosity systems. Vacuum system: Negative pressure reaches -0.095MPa, effectively removing bubbles and preventing oxidation. Hydraulic lifting cylinder: Easy to clean and replace raw materials to prevent cross contamination. Screw extrusion/bottom discharge design: Smooth discharge, suitable for paste and semi-fluid resin system. Stainless steel contact material (SS304/316): Meets medical standards, resi...
