Abstract

The invention discloses an enhanced dry ice formula applied to burrs of a middle frame of a mobile phone and a production process of enhanced dry ice. The enhanced dry ice comprises dry ice and salt,wherein the ratio of the dry ice to the salt is 1:30; through the processing technology of enhanced production equipment, the dry ice particles and the micro-salt particles are fully mixed; the formeddry ice blocks contain harder micro-salt particles, and the mixing ratio is controllable, so that the dry ice for removing the burrs of the middle frame of the mobile phone has higher impact force, the removal effect is better, the consumption of the dry ice is reduced, the cost is reduced, and the enhanced dry ice has the advantages of low cost, large market space, reduction of the reject ratioof products and remarkable burr removal effect.

Description

technical field [0001] The invention relates to the technical field of dry ice production, in particular, the design relates to an enhanced dry ice formula and production process applied to burrs in the middle frame of mobile phones. Background technique [0002] With the development of dry ice technology, the application scenarios of dry ice are becoming more and more extensive. Among them, in the mobile phone case burr grinding process, the block dry ice is scraped into small particles with a scraper, and then the small particles are impacted on the mobile phone case under the action of airflow. On the surface, micro blasting occurs to achieve the purpose of removing the burrs on the mobile phone case. [0003] The dry ice used in this burr removal process is directly transported from the high-pressure side of the storage tank to the low-pressure tablet press through liquid carbon dioxide. Under the compression of the tablet press, the liquid carbon dioxide is directly com...
