【Background technique】

The production process of latex products is the process of converting the fluid latex into solid products through gelation and film formation. Coagulant is an indispensable link in the process of producing latex medical gloves. The most commonly used gelling methods include ion deposition gelation, heat-sensitized gelation, sodium silicofluoride slow gelation, electro-precipitation stain gelation and micro The hole model is gelled. Ion deposition gelation is the use of a coagulant to form a film of latex rubber. The most widely used coagulants for ion deposition are calcium chloride and calcium nitrate. Since natural rubber latex has better self-adhesiveness after film formation, a certain amount of release agent, such as calcium stearate, calcium carbonate, etc., is added to the coagulant.

In the prior art, the coagulant tank all adopts a propeller stirring paddle, and the coagulant mixed solution around the impeller is stirred by the rotation of the stirring blade, so as to achieve the purpose of no precipitation. However, due to the influence of the tank structure, the propeller stirring blade cannot effectively make the coagulant mixed solution flow in the mixing tank from vertical to horizontal, resulting in a small convection range of the coagulant mixed solution in the tank, resulting in the solidification of the upper layer of the tank The surface of the coagulant mixed solution has a gentle convective circulation, and the bottom layer of the coagulant mixed solution is basically still, causing the temperature of the coagulant mixed solution in the tank to be different; and because the solubility of the solute dissolved in water is related to temperature and molecular motion, Low temperature and small external mechanical force are easy to cause precipitation, especially calcium stearate suspension, which is more likely to cause stratified precipitation when standing still.
