When the raw material exceeds the service life, the foaming agent in the EPS raw material will volatilize into the air, which cannot guarantee the correctness of the EPS raw material. If there is too much powder in the raw material, it will block the feed port of the EPS foam mechanical pre-expanding cylinder and the ventilation groove of the pre-expanding cylinder, so that the particles are easy to agglomerate and the foam cloth is uniform.
EPS mechanical steam saturated steam, if needed, whether the steam in the production process is more critical for saturated steam, if the steam pipe is too long, the steam pipe is too small, there is not enough steam pressure in the boiler, the steam can easily It is formed that affects the mechanical quality of the entire EPS product. If the required compressed air is purified, there is no water and dust-free gas. Be sure to prepare before using EPS machinery, otherwise EPS machinery will be easily damaged, and making corresponding preparations can reduce the probability of EPS machinery damage. Conducive to the promotion and application of EPS machinery.
The purpose of factory inspection of foam equipment is to verify the quality and structure of the equipment. All equipment must undergo strict factory inspection before leaving the factory. How to check eps foam equipment?
The appearance of Eps foam equipment is uniform in color, no exposed primer, good paint film adhesion, no flow marks, wrinkling, and slight paint bump defects. The opening and closing of the warehouse door should be flexible, and the power supply of a single device should be switched on and off multiple times to observe whether it can start normally and whether there is abnormal operation.
In functional test systems by stirring and pumping cement and other materials that are difficult to clean, water is usually added, as a solid, rather than the test test material, the foaming test system should use solid materials that foam in a dilute aqueous solution of the foam The size of the spray capsules should be uniform. Check the above aspects of the foaming equipment after coming to the factory.
