The biggest source of pollution for changing lead production is the tetraethyl lead additive in lead smelters and automotive gasoline. At present, the sintering-blast furnace reduction process mainly used in each lead smelter releases a large amount of sulfur dioxide and lead vapor in the production process, causing environmental damage. Serious pollution. Although some manufacturers have invested heavily in making significant improvements on dust collection equipment, lead pollution is still serious. Some new fire method lead-smelting technologies introduced in recent years have alleviated lead pollution to a certain extent, but because of the high temperature operation, the hazard of lead cannot be eradicated. To completely eradicate lead pollution, it is necessary to change the lead production process and replace the current pyrometallurgical lead with wet method lead. With the use of leaded gasoline additives, the contamination of lead contained in automotive exhaust will be controlled.
Existing lead smelters to transform existing lead smelters must increase sulfur dioxide recovery and high-efficiency dust collection devices to achieve lead and sulfur dioxide levels in the emitted flue gas. Lead smelters that fail to pass the dust collection device should be resolutely banned.
Improve the lead workshop environment Lead workshops for lead melting, lead storage battery production, lead salt production, cable production, etc., must use natural ventilation and ventilation facilities, isolated from other workshops, melting lead pots must have temperature control devices, lead liquid temperature Can not exceed 55,000, all kinds of products should be placed in a certain place, the scum should be placed in a special container. The Barton furnace and the ball mill used in the production of lead salt must be completely sealed and equipped with two or more dust collecting devices, and the exhaust gas emission must meet the standard. The floor of the lead salt production workshop shall be a screen type ground, and the screen shall be easy to clean under the screen.

Polypropylene is a kind of thermoplastic synthetic resin with excellent performance. It is a colorless and translucent thermoplastic lightweight general plastic. It has chemical resistance, heat resistance, electrical insulation, high strength mechanical properties and good high wear-resisting processing properties. It is widely used in the production of fiber products such as clothing, blankets, medical devices, automobiles, bicycles, parts, transportation pipes, chemical containers, etc., as well as food and drug packaging
