Today, the editor will tell you how to solve the sticking and punching problem of the automatic high-pressure tablet press:
1. The surface of the punch of the automatic high-pressure tablet press is damaged or its surface finish is reduced. There may also be anti-rust oil or lubricating oil, the surface of the new die is rough or the lettering is too deep with edges and corners. The punch can be cleaned, the non-standard die can be replaced, or a small amount of liquid paraffin can be used to wipe on the surface of the lettering punch to lubricate the words. In addition, if it is caused by mechanical heating, check the cause and repair the equipment.
2. The design of engraving and punching characters is unreasonable. Change the punch or character design accordingly.
3. The particles have too much water content or uneven dry and wet particles, resulting in stickiness and impact. Solution: control the moisture content of particles at about 2%~3%, and strengthen the dry particle inspection.
4. The amount of lubricant is insufficient or the type selection is improper, and there is too much fine powder. The amount of lubricant shall be appropriately increased or new lubricant shall be replaced to remove excessive fine powder.
5. The large difference in fineness of raw and auxiliary materials causes uneven mixing or improper mixing time. Solution: Crush and sift the raw and auxiliary materials to make their fineness meet the quality requirements of the variety, and master and control the mixing time.
6. The adhesive strength is poor due to the low concentration of the adhesive or the quality of the adhesive. The fine powder is too much (more than 10%) and the adhesive is washed. Solution: use a 40-mesh screen to screen out fine powder for re-granulation, drying, granulation, and then mix evenly in the whole batch before tabletting.
7. Sticky impact is caused by the raw material itself (such as wettability). Solution: add a quantitative absorbent (such as 3% calcium hydrogen phosphate) to avoid sticking.
8. The ambient humidity is too high and too high to reduce the ambient humidity.
9. Too high temperature in the operating room is easy to cause stickiness and impact. Pay attention to reducing the temperature of the operating room.
